背景技术Background technique
随着用户对便携性要求的提高，无线耳机得到越来越多的用户的青睐。通常，无线耳机与耳机盒配合使用。耳机盒可以收纳无线耳机，并为无线耳机充电。As users have higher requirements for portability, wireless earphones are favored by more and more users. Typically, wireless headphones are used with a headphone case. The earphone box can store and charge the wireless earphones.
其中，无线耳机上以及耳机盒内可以分别设置有对应的电连接器，该电连接器用于导通和传输电流。当无线耳机收纳于耳机盒中，且无线耳机上的电连接器和耳机盒上的电连接器相接触时，耳机盒与无线耳机建立电连接。耳机盒通过该电连接为无线耳机充电。Wherein, corresponding electrical connectors may be provided on the wireless earphone and in the earphone box respectively, and the electrical connectors are used for conduction and transmission of electric current. When the wireless earphone is stored in the earphone box, and the electrical connector on the wireless earphone is in contact with the electrical connector on the earphone box, the earphone box and the wireless earphone are electrically connected. The earphone case charges the wireless earphones through this electrical connection.
现有技术中，无线耳机可以通过无线耳机是否与耳机盒建立电连接，检测无线耳机的出盒或入盒。具体的，如果无线耳机与耳机盒建立了电连接，无线耳机确定该无线耳机入盒；如果无线耳机与耳机盒断开电连接，无线耳机确定该无线耳机出盒。In the prior art, the wireless earphone can detect whether the wireless earphone is out of the box or in the box by whether the wireless earphone is electrically connected to the earphone box. Specifically, if the wireless earphone is electrically connected to the earphone box, the wireless earphone determines that the wireless earphone is in the box; if the wireless earphone is disconnected from the earphone box, the wireless earphone determines that the wireless earphone is out of the box.

发明内容Contents of the invention
本申请实施例提供一种无线耳机及无线耳机系统，可以提高无线耳机的出入盒检测的准确性。Embodiments of the present application provide a wireless earphone and a wireless earphone system, which can improve the accuracy of detection of a wireless earphone entering and exiting a box.
第一方面，本申请实施例提供一种无线耳机。该无线耳机包括处理器，以及与处理器耦合的磁传感器。其中，该无线耳机收纳在耳机盒的收纳腔内时，该无线耳机周围的磁场是第一磁场。磁传感器在该第一磁场检测的磁感应强度在第一强度区间。该无线耳机在耳机盒的收纳腔外时，该无线耳机周围的磁场是第二磁场。磁传感器在该第二磁场检测的磁感应强度在第二强度区间。该第一强度区间与第二强度区间没有交集。In a first aspect, the embodiment of the present application provides a wireless earphone. The wireless headset includes a processor, and a magnetic sensor coupled to the processor. Wherein, when the wireless earphone is stored in the storage cavity of the earphone box, the magnetic field around the wireless earphone is the first magnetic field. The magnetic induction detected by the magnetic sensor in the first magnetic field is in the first intensity interval. When the wireless earphone is outside the storage cavity of the earphone box, the magnetic field around the wireless earphone is the second magnetic field. The magnetic induction detected by the magnetic sensor in the second magnetic field is within the second intensity range. The first intensity interval does not intersect with the second intensity interval.
具体的，该磁传感器可以用于：检测无线耳机周围的磁场的磁感应强度；如果检测到磁感应强度在所述第一强度区间，向处理器输出第一信号；如果检测到磁感应强度在第二强度区间，向处理器输出第二信号。其中，上述第一信号是高电平，第二信号是低电平；或者，第一信号是低电平，第二信号是高电平。Specifically, the magnetic sensor can be used to: detect the magnetic induction intensity of the magnetic field around the wireless earphone; if it is detected that the magnetic induction intensity is in the first intensity range, output the first signal to the processor; if it is detected that the magnetic induction intensity is in the second intensity range interval, and output the second signal to the processor. Wherein, the above-mentioned first signal is at a high level, and the second signal is at a low level; or, the first signal is at a low level, and the second signal is at a high level.
示例性的，上述第一磁场可以包括无线耳机中的磁体产生的磁场和耳机盒中的磁体产生的磁场。上述第二磁场可以包括无线耳机中的磁体产生的磁场。也就是说，无线耳机在耳机盒内的磁场，与无线耳机在耳机盒外的磁场不同。因此，磁传感器在耳机盒内与耳机盒外可以检测到不同的磁感应强度。Exemplarily, the above-mentioned first magnetic field may include a magnetic field generated by a magnet in the wireless earphone and a magnetic field generated by a magnet in the earphone box. The above-mentioned second magnetic field may include a magnetic field generated by a magnet in the wireless earphone. That is to say, the magnetic field of the wireless earphone inside the earphone box is different from the magnetic field of the wireless earphone outside the earphone box. Therefore, the magnetic sensor can detect different magnetic induction intensities inside the earphone box and outside the earphone box.
一般而言，无线耳机中的磁体产生的磁场，以及耳机盒内的磁体产生的磁场都是相对固定的。因此，无论无线耳机在耳机盒内或者耳机盒外，磁传感器检测到的磁感应强度都可以在一定强度区间(如上述第一强度区间或第二强度区间)内的。因此，磁传感器可以根据检测的磁感应强度在第一强度区间或第二强度区间，向处理器输出高电平或者低电平。处理器可以根据磁传感器传输的高低电平的跳变，确定无线耳机的出盒或入盒。Generally speaking, the magnetic field generated by the magnet in the wireless earphone and the magnetic field generated by the magnet in the earphone box are relatively fixed. Therefore, no matter whether the wireless earphone is in the earphone box or outside the earphone box, the magnetic induction intensity detected by the magnetic sensor can be within a certain intensity interval (such as the above-mentioned first intensity interval or the second intensity interval). Therefore, the magnetic sensor can output a high level or a low level to the processor in the first intensity interval or the second intensity interval according to the detected magnetic induction intensity. The processor can determine the out-of-box or in-box of the wireless earphone according to the high and low level transitions transmitted by the magnetic sensor.
其中，无线耳机根据磁场的磁感应强度的变化检测无线耳机的出盒和入盒时，检测结果不会因为耳机盒和无线耳机的接触接触不良，而导致对无线耳机出盒或入盒的误判。上述检测方式是一种非接触是检测方式，可以提高无线耳机的出入盒检测的准确性。Among them, when the wireless earphone detects the out-of-box and in-box of the wireless earphone according to the change of the magnetic induction intensity of the magnetic field, the detection result will not cause a misjudgment of the out-of-box or in-box of the wireless earphone due to poor contact between the earphone box and the wireless earphone . The above-mentioned detection method is a non-contact detection method, which can improve the accuracy of detection of the wireless earphone in and out of the box.
在一种可能的设计中，上述第一磁场的磁场强度可能大于第二磁场的磁场强度。或者，上述第一磁场的磁场强度可能小于第二磁场的磁场强度。其中，第一磁场和第二磁场的磁场强度的大小决定于耳机盒和无线耳机中各个磁体的磁场的磁矢量的大小和方向。In a possible design, the magnetic field strength of the above-mentioned first magnetic field may be greater than the magnetic field strength of the second magnetic field. Or, the magnetic field strength of the above-mentioned first magnetic field may be smaller than the magnetic field strength of the second magnetic field. Wherein, the magnitudes of the magnetic field strengths of the first magnetic field and the second magnetic field are determined by the magnitude and direction of the magnetic vectors of the magnetic fields of the respective magnets in the earphone box and the wireless earphone.
在第一种情况下，上述第一磁场的磁场强度大于第二磁场的磁场强度；因此，第一强度区间的最小磁感应强度大于第二强度区间的最大感应强度。在这种情况下，上述处理器具体可以用于：在磁传感器检测的磁感应强度变小，由第一强度区间切换至第二强度区间时，确定无线耳机出盒；在磁传感器检测的磁感应强度变大，由第二强度区间切换至第一强度区间时，确定无线耳机入盒。In the first case, the magnetic field strength of the first magnetic field is greater than the magnetic field strength of the second magnetic field; therefore, the minimum magnetic induction intensity in the first intensity interval is greater than the maximum induction intensity in the second intensity interval. In this case, the above-mentioned processor can be specifically used to: determine that the wireless earphone is out of the box when the magnetic induction intensity detected by the magnetic sensor becomes smaller and switches from the first intensity interval to the second intensity interval; becomes larger, when switching from the second intensity range to the first intensity range, it is determined that the wireless earphone is in the box.
在第二种情况下，上述第一磁场的磁场强度小于第二磁场的磁场强度；因此，第一强度区域的最大磁感应强度小于第二强度区域的最小磁感应强度。在这种情况下，上述处理器具体可以用于：在磁传感器检测的磁感应强度变大，由第一强度区间切换至第二强度区间时，确定无线耳机出盒；在磁传感器检测的磁感应强度变小，由第二强度区间切换至第一强度区间时，确定无线耳机入盒。In the second case, the magnetic field strength of the first magnetic field is smaller than that of the second magnetic field; therefore, the maximum magnetic induction in the first strength region is smaller than the minimum magnetic induction in the second strength region. In this case, the above processor can be specifically used to: determine that the wireless earphone is out of the box when the magnetic induction intensity detected by the magnetic sensor becomes larger and switches from the first intensity interval to the second intensity interval; becomes smaller, when switching from the second intensity range to the first intensity range, it is determined that the wireless earphone is in the box.
在另一种可能的设计中，上述磁传感器可以是第一类磁传感器。该第一类传感器具备“在检测到磁感应强度大于一个磁感应强度门限时，向处理器输出第一信号；在检测到磁感应强度小于另一个磁感应强度门限时，向处理器输出第二信号”的特性。例如，该第一类磁传感器可以是霍尔传感器。该种可能的设计提供了磁传感器可能的产品形态。In another possible design, the above-mentioned magnetic sensor may be a first-type magnetic sensor. The first type of sensor has the characteristic of "outputting a first signal to the processor when detecting that the magnetic induction intensity is greater than a magnetic induction intensity threshold; outputting a second signal to the processor when detecting that the magnetic induction intensity is less than another magnetic induction intensity threshold" . For example, the first type of magnetic sensor may be a Hall sensor. This possible design provides a possible product form of the magnetic sensor.
结合上述第一种情况，上述第一强度区间的最小磁感应强度和第二强度区间的最大感应强度是该第一类磁传感器的两个磁感应强度门限。In combination with the above first case, the minimum magnetic induction intensity in the first intensity interval and the maximum induction intensity in the second intensity interval are the two magnetic induction intensity thresholds of the first type of magnetic sensor.
结合上述第二种情况，上述第二强度区间的最小磁感应强度和第一强度区间的最大感应强度是该第一类磁传感器的两个磁感应强度门限。In combination with the second case above, the minimum magnetic induction intensity in the second intensity interval and the maximum induction intensity in the first intensity interval are the two magnetic induction intensity thresholds of the first type of magnetic sensor.
在另一种可能的设计中，结合上述第一种情况，为了避免用户将无线耳机从耳机盒取出和放入的过程中，由于无线耳机没有完全取出或放入收纳腔而导致无线耳机检测到无线耳机频繁出盒/入盒。上述磁传感器(即霍尔传感器)还可以用于：在检测到磁感应强度在第一强度区间之后，如果检测到磁感应强度小于第一强度区域的最小磁感应强度，且大于第二强度区域的最大磁感应强度，则向处理器输出第一信号；在检测到磁感应强度在第二强度区间之后，如果检测到磁感应强度大于第二强度区域的最大磁感应强度，且小于第一强度区域的最小磁感应强度，则向处理器输出第二信号。In another possible design, in combination with the above-mentioned first situation, in order to prevent the wireless earphone from detecting the Wireless headphones come out of/in the box frequently. The above-mentioned magnetic sensor (that is, Hall sensor) can also be used: after detecting that the magnetic induction intensity is in the first intensity interval, if it is detected that the magnetic induction intensity is less than the minimum magnetic induction intensity of the first intensity area, and greater than the maximum magnetic induction intensity of the second intensity area intensity, then output the first signal to the processor; after detecting that the magnetic induction intensity is in the second intensity interval, if it is detected that the magnetic induction intensity is greater than the maximum magnetic induction intensity in the second intensity area and less than the minimum magnetic induction intensity in the first intensity area, then Output the second signal to the processor.
在另一种可能的设计中，结合上述第二种情况，为了避免用户将无线耳机从耳机盒取出和放入的过程中，由于无线耳机没有完全取出或放入收纳腔而导致无线耳机检测到无线耳机频繁出盒/入盒。上述磁传感器(即霍尔传感器)还可以用于：在检测到磁感应强度在第一强度区间之后，如果检测到磁感应强度大于第一强度区域的最大磁感应强度，且小于第二强度区域的最小磁感应强度，则向处理器输出第一信号；在检测到磁感应强度在第二强度区间之后，如果检测到磁感应强度小于第二强度区域的最小磁感应强度，且大于第一强度区域的最大磁感应强度，则向处理器输出第二信号。In another possible design, in combination with the above-mentioned second situation, in order to prevent the wireless earphone from being detected by the wireless earphone because the wireless earphone is not completely taken out Wireless headphones come out of/in the box frequently. The above-mentioned magnetic sensor (that is, the Hall sensor) can also be used: after detecting that the magnetic induction intensity is in the first intensity interval, if it is detected that the magnetic induction intensity is greater than the maximum magnetic induction intensity in the first intensity area and less than the minimum magnetic induction intensity in the second intensity area intensity, then output the first signal to the processor; after detecting that the magnetic induction intensity is in the second intensity interval, if it is detected that the magnetic induction intensity is less than the minimum magnetic induction intensity in the second intensity area and greater than the maximum magnetic induction intensity in the first intensity area, then Output the second signal to the processor.
在另一种可能的设计中，上述磁传感器是霍尔传感器时，该磁传感器可以通过输入/输出(Input/Output，IO)引脚或者中断引脚连接处理器。In another possible design, when the above-mentioned magnetic sensor is a Hall sensor, the magnetic sensor may be connected to the processor through an input/output (Input/Output, IO) pin or an interrupt pin.
该种可能的设计提供了磁传感器(如霍尔传感器)与处理器可能的耦合方式。This possible design provides a possible coupling mode between the magnetic sensor (such as a Hall sensor) and the processor.
第二方面，本申请实施例提供一种无线耳机。该无线耳机包括处理器，以及与处理器耦合的磁传感器。该磁传感器用于：检测无线耳机周围的磁场的磁感应强度；向处理器传输检测的磁感应强度。该处理器，用于在磁传感器检测的磁感应强度由第一强度区间切换至第二强度区间时，确定无线耳机出盒；在磁传感器检测的磁感应强度由第二强度区间切换至第一强度区间时，确定无线耳机入盒。In a second aspect, the embodiment of the present application provides a wireless earphone. The wireless headset includes a processor, and a magnetic sensor coupled to the processor. The magnetic sensor is used for: detecting the magnetic induction intensity of the magnetic field around the wireless earphone; and transmitting the detected magnetic induction intensity to the processor. The processor is configured to determine that the wireless earphone is out of the box when the magnetic induction intensity detected by the magnetic sensor is switched from the first intensity interval to the second intensity interval; when the magnetic induction intensity detected by the magnetic sensor is switched from the second intensity interval to the first intensity interval , make sure the wireless headset is in the box.
其中，由上述第一方面中的描述可知：磁传感器在耳机盒内与耳机盒外可以检测到不同的磁感应强度；无线耳机在耳机盒内时，磁感应强度在第一强度区间；无线耳机在耳机盒外时，磁感应强度在第二强度区间。因此，处理器可以根据磁传感器检测到的磁感应强度在第一强度区间和第二强度区间的变化，检测无线耳机的出盒和入盒。Among them, it can be seen from the description in the first aspect above that: the magnetic sensor can detect different magnetic induction intensities inside the earphone box and outside the earphone box; when the wireless earphone is in the earphone box, the magnetic induction intensity is in the first intensity range; When outside the box, the magnetic induction intensity is in the second intensity range. Therefore, the processor can detect the out-of-box and in-box of the wireless earphone according to the change of the magnetic induction intensity detected by the magnetic sensor between the first intensity interval and the second intensity interval.
其中，根据磁场的磁感应强度的变化检测无线耳机的出盒和入盒时，检测结果不会因为耳机盒和无线耳机的接触接触不良，而导致对无线耳机出盒或入盒的误判。上述检测方式是一种非接触是检测方式，可以提高无线耳机的出入盒检测的准确性。Among them, when the out-of-box and in-box of the wireless earphone are detected according to the change of the magnetic induction intensity of the magnetic field, the detection result will not cause a misjudgment of the out-of-box or in-box of the wireless earphone due to poor contact between the earphone box and the wireless earphone. The above-mentioned detection method is a non-contact detection method, which can improve the accuracy of detection of the wireless earphone in and out of the box.
在一种可能的设计中，在第一种情况下，第一磁场的磁场强度大于第二磁场的磁场强度。在第二种情况下，第一磁场的磁场强度小于第二磁场的磁场强度。其中，第一种情况和第二种情况下，第一强度区间和第二强度区间的详细描述，可以参考上述第一方面的可能的设计中的描述，本申请实施例这里不再赘述。In a possible design, in the first case, the magnetic field strength of the first magnetic field is greater than the magnetic field strength of the second magnetic field. In the second case, the magnetic field strength of the first magnetic field is smaller than the magnetic field strength of the second magnetic field. Wherein, for the detailed description of the first intensity interval and the second intensity interval in the first case and the second case, reference may be made to the description in the possible design of the first aspect above, and the embodiments of the present application will not repeat them here.
在另一种可能的设计中，上述磁传感器可以是第二类磁传感器。该第二类传感器不会判断检测到的磁感应强度是否大于某个磁感应门限或者判断磁感应强度是否在某个强度区间内；而是会直接向处理器传输检测到的磁感应强度。例如，该第二类磁传感器可以是磁力计。当然，可能还会有一部分霍尔传感器也属于第二类磁传感器，本申请实施例对此不做限制。也就是说，上述磁传感器具体可以有多种产品形态。In another possible design, the above magnetic sensor may be a second type of magnetic sensor. The second type of sensor will not judge whether the detected magnetic induction intensity is greater than a certain magnetic induction threshold or whether the magnetic induction intensity is within a certain intensity range; instead, it will directly transmit the detected magnetic induction intensity to the processor. For example, the second type of magnetic sensor may be a magnetometer. Of course, some Hall sensors may also belong to the second type of magnetic sensors, which is not limited in this embodiment of the present application. That is to say, the above-mentioned magnetic sensor may have various product forms.
在另一种可能的设计中，上述处理器还可以用于：在磁传感器检测的磁感应强度由第一强度区域切换至第三强度区间时，确定无线耳机收纳于耳机盒的收纳腔内；在磁传感器检测的磁感应强度由第二强度区域切换至第三强度区间时，确定无线耳机在耳机盒的收纳腔外。In another possible design, the above-mentioned processor can also be used to: determine that the wireless earphone is stored in the storage cavity of the earphone box when the magnetic induction intensity detected by the magnetic sensor is switched from the first intensity range to the third intensity range; When the magnetic induction detected by the magnetic sensor is switched from the second intensity range to the third intensity range, it is determined that the wireless earphone is outside the storage cavity of the earphone box.
结合上述第一种情况，上述第三强度区间的边界值为：第一强度区域的最小磁感应强度和第二强度区域的最大磁感应强度。结合上述第二种情况，上述第三强度区间的边界值为：第二强度区域的最小磁感应强度和第一强度区域的最大磁感应强度。该第三强度区间与第一强度区间没有交集，且该第三强度区间与第二强度区间没有交集。In combination with the above first case, the boundary values of the above third intensity interval are: the minimum magnetic induction intensity in the first intensity area and the maximum magnetic induction intensity in the second intensity area. In combination with the second case above, the boundary values of the third intensity interval are: the minimum magnetic induction intensity in the second intensity area and the maximum magnetic induction intensity in the first intensity area. The third intensity interval has no intersection with the first intensity interval, and the third intensity interval has no intersection with the second intensity interval.
可以理解，在用户将无线耳机从耳机盒取出和放入的过程中，磁传感器检测到的磁感应强度可能并不在上述第一强度区间或第二强度区间内。在上述取出的过程中，磁传感器检测到的磁感应强度可能会由第一强度区间先切换至第三强度区间，然后再切换至第二强度区间。在上述放入的过程中，磁传感器检测到的磁感应强度可能会由第二强度区间先切换至第三强度区间，然后再切换至第一强度区间。It can be understood that when the user takes out and puts the wireless earphone out of the earphone box, the magnetic induction intensity detected by the magnetic sensor may not be within the above-mentioned first intensity range or the second intensity range. During the above-mentioned taking-out process, the magnetic induction detected by the magnetic sensor may first switch from the first intensity range to the third intensity range, and then switch to the second intensity range. During the above-mentioned insertion process, the magnetic induction detected by the magnetic sensor may first switch from the second intensity range to the third intensity range, and then switch to the first intensity range.
采用该种可能的设计，可以避免上述取出和放入的过程中，由于无线耳机没有完全取出或放入收纳腔，使得磁传感器检测到的磁感应强度在第三强度区间而导致无线耳机检测到无线耳机频繁出盒/入盒。采用该种可能的设计，可以避免无线耳机检测到无线耳机频繁出盒/入盒，提高了无线耳机的出入盒检测的准确性。With this possible design, it is possible to avoid the above-mentioned process of taking out and putting in, because the wireless earphone is not completely taken out or put into the storage cavity, so that the magnetic induction intensity detected by the magnetic sensor is in the third intensity range, which causes the wireless earphone to detect the wireless Headphones come out/in the box frequently. With this possible design, the wireless earphone can be prevented from detecting that the wireless earphone is frequently out of the box or in the box, and the accuracy of the detection of the wireless earphone in and out of the box can be improved.
在另一种可能的设计中，上述磁传感器通过数据总线连接处理器。其中，该数据总线包括串行外设接口(serial peripheral interface，SPI)、集成电路(inter-integratedcircuit，I2C)接口或者改进的集成电路(improved inter-integrated circuit，I3C)接口。In another possible design, the magnetic sensor is connected to the processor through a data bus. Wherein, the data bus includes a serial peripheral interface (serial peripheral interface, SPI), an integrated circuit (inter-integrated circuit, I2C) interface or an improved integrated circuit (improved inter-integrated circuit, I3C) interface.
该种可能的设计提供了磁传感器(如磁力计)与处理器可能的耦合方式。This possible design provides a possible coupling mode between the magnetic sensor (such as a magnetometer) and the processor.
在第一方面或第二方面的另一种可能的设计中，结合上述第一种情况，第一强度区间的最大磁感应强度可以为无穷大，第二强度区间的最小感应强度可以为零。In another possible design of the first aspect or the second aspect, in combination with the above-mentioned first case, the maximum magnetic induction intensity in the first intensity interval may be infinite, and the minimum induction intensity in the second intensity interval may be zero.
也就是说，无线耳机在进行出入盒检测时，可以只使用两个磁感应强度门限(如第一强度区间的最小磁感应强度和第二强度区间的最大感应强度)来对比磁传感器检测的磁感应强度。That is to say, when the wireless earphone performs box entry and exit detection, it can only use two magnetic induction intensity thresholds (such as the minimum magnetic induction intensity in the first intensity interval and the maximum induction intensity in the second intensity interval) to compare the magnetic induction intensity detected by the magnetic sensor.
例如，上述第一类磁传感器可以用于：在检测的磁感应强度大于第一强度区间的最小磁感应强度时，向处理器输出第一信号；在检测的磁感应强度小于第二强度区间的最大磁感应强度时，向处理器输出第二信号。For example, the above-mentioned first type of magnetic sensor can be used to: output the first signal to the processor when the detected magnetic induction intensity is greater than the minimum magnetic induction intensity in the first intensity interval; when the detected magnetic induction intensity is less than the maximum magnetic induction intensity in the second intensity interval , outputting a second signal to the processor.
在第一方面或第二方面的另一种可能的设计中，结合上述第二种情况，第一强度区间的最小磁感应强度可以为零，第二强度区间的最大感应强度可以为无穷大。In another possible design of the first aspect or the second aspect, in combination with the above-mentioned second case, the minimum magnetic induction intensity in the first intensity interval may be zero, and the maximum induction intensity in the second intensity interval may be infinite.

在第一方面或第二方面的另一种可能的设计中，结合上述第一种情况，第一强度区间的最大磁感应强度可以为无穷大，第二强度区间的最小感应强度可以为零。并且，第一强度区间的最小磁感应强度可以等于第二强度区间的最大感应强度。In another possible design of the first aspect or the second aspect, in combination with the above-mentioned first case, the maximum magnetic induction intensity in the first intensity interval may be infinite, and the minimum induction intensity in the second intensity interval may be zero. Moreover, the minimum magnetic induction intensity in the first intensity interval may be equal to the maximum induction intensity in the second intensity interval.

为了使得无线耳机在盒内和盒外时，磁传感器检测到的磁感应强度的差异更加明显；上述耳机盒中还可以设置有第一磁体。In order to make the difference between the magnetic induction intensity detected by the magnetic sensor more obvious when the wireless earphone is inside and outside the box; the earphone box may also be provided with a first magnet.
其中，该第一磁体与无线耳机的磁传感器对应。其中，第一磁体与无线耳机的磁传感器对应可以体现在以下两个方面。Wherein, the first magnet corresponds to the magnetic sensor of the wireless earphone. Wherein, the correspondence between the first magnet and the magnetic sensor of the wireless earphone can be embodied in the following two aspects.
(一)：该第一磁体的设置是为了使无线耳机在盒内和盒外时，磁传感器检测到的磁感应强度的差异更加明显；而不是为了实现耳机盒的其他功能(如吸附无线耳机，实现盒身与盒盖之间闭合吸附或者增强充电引脚压力等功能)。(1): The setting of the first magnet is to make the difference between the magnetic induction intensity detected by the magnetic sensor more obvious when the wireless earphone is inside and outside the box; it is not to realize other functions of the earphone box (such as absorbing the wireless earphone, Realize the closed adsorption between the box body and the box cover or enhance the pressure of the charging pin, etc.).

A storage cavity of the earphone box can be divided into two parts: a first cavity and a second cavity. Wherein, the first cavity is used for accommodating the earplug of the wireless earphone, and the second cavity is used for accommodating the rod body of the wireless earphone. When the magnetic sensor is arranged in the earplug of the wireless earphone, the first magnet can be arranged in the earphone box at a position close to the first cavity of the earphone box. When the magnetic sensor is arranged in the rod body of the wireless earphone, the first magnet can be arranged in the earphone box, close to the second cavity of the earphone box.

It can be understood that when the earphone body 41 is the earphone body 300 shown in FIG. 3 , the magnetic sensor 411 may be the magnetic sensor 307A shown in FIG. 3 , and the processor 412 may be the processor 301 shown in FIG. 3 .
示例性的，磁传感器411通过处理器412的IO引脚或者中断引脚与处理器412耦合。或者，磁传感器411可以通过数据总线与处理器412耦合。例如，该数据总线可以是SPI总线、I2C总线或I3C总线中的至少一个。上述处理器412可以是微处理器。微处理器是由一片或少数几片大规模集成电路组成的中央处理器。Exemplarily, the magnetic sensor 411 is coupled to the processor 412 through an IO pin or an interrupt pin of the processor 412 . Alternatively, magnetic sensor 411 may be coupled to processor 412 via a data bus. For example, the data bus may be at least one of an SPI bus, an I2C bus or an I3C bus. The aforementioned processor 412 may be a microprocessor. A microprocessor is a central processing unit composed of one or a few large-scale integrated circuits.
本申请实施例这里对上述磁传感器411进行说明。In this embodiment of the present application, the above-mentioned magnetic sensor 411 is described here.
上述磁传感器411可以是第一类磁传感器(如霍尔传感器)或者第二类磁传感器(如磁力计)。The above-mentioned magnetic sensor 411 may be a first-type magnetic sensor (such as a Hall sensor) or a second-type magnetic sensor (such as a magnetometer).
第一类磁传感器具备以下特性：(1)用于检测周围的磁场的磁感应强度；(2)在检测到磁感应强度大于一个磁感应强度门限(称为第一强度门限)时，向处理器输出第一信号；在检测到磁感应强度小于另一个磁感应强度门限(称为第二强度门限)时，向处理器输出第二信号；(3)第一强度门限和第二强度门限是固定的，由磁传感器的硬件结构决定。其中，上述第一信号是高电平，第二信号是低电平；或者，第一信号是低电平，第二信号是高电平。由于上述第一类磁传感器的磁感应强度门限由磁传感器的硬件结构决定；因此，第一类磁传感器也可以称为硬件门限磁传感器。The first type of magnetic sensor has the following characteristics: (1) for detecting the magnetic induction intensity of the surrounding magnetic field; (2) when the magnetic induction intensity is detected to be greater than a magnetic induction intensity threshold (called the first intensity threshold), output the first intensity threshold to the processor A signal; when detecting that the magnetic induction intensity is less than another magnetic induction intensity threshold (called the second intensity threshold), a second signal is output to the processor; (3) the first intensity threshold and the second intensity threshold are fixed, determined by the magnetic induction The hardware structure of the sensor is determined. Wherein, the above-mentioned first signal is at a high level, and the second signal is at a low level; or, the first signal is at a low level, and the second signal is at a high level. Since the magnetic induction intensity threshold of the first type of magnetic sensor is determined by the hardware structure of the magnetic sensor; therefore, the first type of magnetic sensor can also be called a hardware threshold magnetic sensor.
第二类磁传感器具备以下特性：(a)用于检测周围的磁场的磁感应强度；(b)向处理器传输检测到的磁感应强度。也就是说，第二类磁传感器检测到磁感应强度后，不会采用磁感应强度门限对磁感应强度的大小进行判定，而是直接向处理器传输检测到的磁感应强度。本申请实施例中，使用第二类磁传感器进行出入盒检测时，所采用的磁感应强度门限是通过软件设置的，与磁传感器的硬件结构无关；因此，第二类磁传感器也可以称为软件门限磁传感器。The second type of magnetic sensor has the following characteristics: (a) for detecting the magnetic induction of the surrounding magnetic field; (b) transmitting the detected magnetic induction to the processor. That is to say, after the second type of magnetic sensor detects the magnetic induction intensity, it does not use the magnetic induction intensity threshold to determine the magnitude of the magnetic induction intensity, but directly transmits the detected magnetic induction intensity to the processor. In the embodiment of the present application, when the second type of magnetic sensor is used for box entry and exit detection, the magnetic induction intensity threshold used is set by software and has nothing to do with the hardware structure of the magnetic sensor; therefore, the second type of magnetic sensor can also be called software Threshold magnetic sensor.

其中，耳机主体41收纳在耳机盒42的收纳腔内时，耳机主体41周围的磁场是第一磁场。磁传感器(如磁传感器411)在该第一磁场检测的磁感应强度在第一强度区间。Wherein, when the earphone main body 41 is stored in the storage cavity of the earphone box 42 , the magnetic field around the earphone main body 41 is the first magnetic field. The magnetic induction intensity detected by the magnetic sensor (such as the magnetic sensor 411 ) in the first magnetic field is within the first intensity range.
示例性的，该第一磁场至少可以包括：耳机本体41中的磁体产生磁场和耳机盒42中的磁体产生的磁场，即耳机本体41中的磁体和耳机盒42中的磁体产生的合磁场。Exemplarily, the first magnetic field may at least include: the magnetic field generated by the magnet in the earphone body 41 and the magnetic field generated by the magnet in the earphone box 42, that is, the resultant magnetic field generated by the magnet in the earphone body 41 and the magnet in the earphone box 42.
示例性的，耳机本体41中的磁体可以包括：扬声器(也称为“喇叭”)中的磁体。可选的，耳机本体41中的磁体还可以包括：用于吸附耳机盒42使得耳机本体41收纳于耳机盒42的收纳腔内的磁体。Exemplarily, the magnet in the earphone body 41 may include: a magnet in a speaker (also referred to as a "speaker"). Optionally, the magnet in the earphone body 41 may also include: a magnet for absorbing the earphone box 42 so that the earphone body 41 is stored in the storage cavity of the earphone box 42 .
耳机盒42中的磁体可以包括以下一个或多个磁体，如用于吸附耳机本体41使得耳机本体41收纳于耳机盒42的收纳腔内的磁体；用于盒身与盒盖之间闭合吸附的磁体；以及用于增强耳机盒42与耳机本体41充电引脚压力的磁体。其中，耳机盒42与耳机本体41充电引脚可以是耳机盒42与耳机本体41的电连接器。The magnets in the earphone box 42 may include one or more of the following magnets, such as magnets for absorbing the earphone body 41 so that the earphone body 41 is accommodated in the receiving chamber of the earphone box 42; Magnets; and magnets for enhancing the pressure on the charging pins of the earphone box 42 and the earphone body 41 . Wherein, the charging pins of the earphone box 42 and the earphone body 41 may be electrical connectors between the earphone box 42 and the earphone body 41 .
(2)第二强度区间。(2) Second intensity interval.
其中，耳机主体41在耳机盒42的收纳腔外时，耳机主体41周围的磁场是第二磁场。磁传感器(如磁传感器411)在该第二磁场检测的磁感应强度在第二强度区间。第一强度区间与第二强度区间没有交集。Wherein, when the earphone main body 41 is outside the storage cavity of the earphone box 42 , the magnetic field around the earphone main body 41 is the second magnetic field. The magnetic induction intensity detected by the magnetic sensor (such as the magnetic sensor 411 ) in the second magnetic field is within the second intensity range. The first intensity interval does not intersect with the second intensity interval.
本申请实施例中，当耳机本体41收纳在耳机盒42内时，称该耳机本体41处于盒内状态；当耳机本体41置于耳机盒42外时，称该耳机本体41处于盒外状态。In the embodiment of the present application, when the earphone body 41 is stored in the earphone box 42, the earphone body 41 is said to be in the box state; when the earphone body 41 is placed outside the earphone box 42, the earphone body 41 is said to be in the out-of-box state.
一般而言，耳机本体41处于盒外状态时，磁传感器411至少可以检测到耳机本体41中的磁体所产生的磁场(也可以是耳机本体41中的多个磁体产生的合磁场)的磁感应强度。也就是说，上述第二磁场至少可以包括：耳机本体41中的磁体所产生的磁场。Generally speaking, when the earphone body 41 is in the state outside the box, the magnetic sensor 411 can at least detect the magnetic induction intensity of the magnetic field generated by the magnet in the earphone body 41 (or the resultant magnetic field generated by a plurality of magnets in the earphone body 41). . That is to say, the above-mentioned second magnetic field may at least include: the magnetic field generated by the magnet in the earphone body 41 .
当然，当耳机本体41置于耳机盒42外，但耳机本体41与耳机盒42之间的距离较近时，耳机盒42中的磁体也影响耳机本体41周围的磁场，从而影响耳机本体41检测到的磁感应强度的大小。其中，相比于盒内状态，耳机本体41处于盒外状态时，耳机盒42中的磁体对耳机本体41周围的磁场的影响较小，从而对耳机本体41检测到的磁感应强度的大小的影响也较小，可以忽略不计。本申请实施例中，为了描述方便，当耳机本体41处于盒外状态时，忽略耳机盒42中的磁体对耳机本体41周围的磁场的影响。Of course, when the earphone body 41 is placed outside the earphone box 42, but the distance between the earphone body 41 and the earphone box 42 is relatively close, the magnet in the earphone box 42 also affects the magnetic field around the earphone body 41, thereby affecting the detection of the earphone body 41. to the magnitude of the magnetic induction. Wherein, compared with the state inside the box, when the earphone body 41 is in the out-of-box state, the magnet in the earphone box 42 has less influence on the magnetic field around the earphone body 41, thereby affecting the magnitude of the magnetic induction intensity detected by the earphone body 41. Also small and negligible. In the embodiment of the present application, for convenience of description, when the earphone body 41 is in the out-of-box state, the influence of the magnet in the earphone box 42 on the magnetic field around the earphone body 41 is ignored.
需要说明的是，无论耳机本体41处于盒外状态或者盒内状态，耳机本体41周围的磁场都会受到耳机本体41周围环境中各个磁体(如周围的电子产品中的磁体)所产生的磁场和地磁场的影响。本申请实施例中，为了描述方便，可以忽略地磁场和耳机本体41周围环境中磁体所产生的磁场对耳机本体41周围的磁场的影响。当然，实际产品的参数设置不会忽略上述磁体对耳机本体41周围磁场的影响。It should be noted that no matter whether the earphone body 41 is in the state outside the box or in the box, the magnetic field around the earphone body 41 will be affected by the magnetic field and ground generated by various magnets in the surrounding environment of the earphone body 41 (such as the magnets in the surrounding electronic products). The influence of the magnetic field. In the embodiment of the present application, for the convenience of description, the influence of the earth's magnetic field and the magnetic field generated by the magnets in the surrounding environment of the earphone body 41 on the magnetic field around the earphone body 41 can be ignored. Of course, the parameter setting of the actual product will not ignore the influence of the above-mentioned magnets on the magnetic field around the earphone body 41 .
综上所述，耳机本体41处于盒内状态时，磁传感器411可以检测到耳机本体41中的磁体和耳机盒42中的磁体所产生的合磁场的磁感应强度；而耳机本体处于盒外状态时，磁传感器411可以检测到耳机本体41中的磁体所产生的磁场的磁感应强度。由此可见，耳机本体41处于不同的状态(如盒内状态或盒外状态)时，磁传感器411检测到的磁感应强度不同。In summary, when the earphone body 41 is in the box state, the magnetic sensor 411 can detect the magnetic induction intensity of the resultant magnetic field produced by the magnet in the earphone body 41 and the magnet in the earphone box 42; , the magnetic sensor 411 can detect the magnetic induction intensity of the magnetic field generated by the magnet in the earphone body 41 . It can be seen that when the earphone body 41 is in different states (such as the state inside the box or the state outside the box), the magnetic induction intensity detected by the magnetic sensor 411 is different.
进一步的，为了使得耳机本体41处于盒内状态和盒外状态时，磁传感器411检测到的磁感应强度的差异更加明显。本申请实施例中，可以在耳机盒42中设置第一磁体。其中，耳机盒中可以设置一个或多个第一磁体。例如，如图4A或图4B所示，耳机盒42中设置有两个第一磁体421。该第一磁体421是区别于上述一个或多个磁体之外的磁体。该第一磁体421的设置是为了使耳机本体41处于盒内状态和盒外状态时，磁传感器411检测到的磁感应强度的差异更加明显；而不是为了实现耳机盒42的其他功能(如吸附耳机本体41，实现盒身与盒盖之间闭合吸附或者增强充电引脚压力等功能)。当然，该第一磁体也可以用于增强上述其他功能，如盒身与盒盖之间闭合吸附功能。Further, in order to make the difference of the magnetic induction intensity detected by the magnetic sensor 411 more obvious when the earphone body 41 is in the state of the box and the state of the outside of the box. In the embodiment of the present application, a first magnet may be provided in the earphone box 42 . Wherein, one or more first magnets may be arranged in the earphone box. For example, as shown in FIG. 4A or FIG. 4B , two first magnets 421 are disposed in the earphone box 42 . The first magnet 421 is a magnet different from the above one or more magnets. The setting of the first magnet 421 is to make the difference of the magnetic induction intensity detected by the magnetic sensor 411 more obvious when the earphone body 41 is in the state inside the box and the state outside the box; rather than for realizing other functions of the earphone box 42 (such as absorbing earphones) The main body 41 realizes functions such as closing and absorbing between the box body and the box cover or enhancing the pressure of the charging pin). Of course, the first magnet can also be used to enhance the above-mentioned other functions, such as the closed adsorption function between the box body and the box cover.

As shown in FIG. 4D , the earphone body 41 may include a rod body 4 a, and an earplug 4 b connected to the top of the rod body 4 a. The inside of the rod body 4a and the earplug 4b may include internal components such as circuit boards and batteries. Various components such as a processor 412 , a memory, and a charging circuit may be included on the circuit board to realize various functions of the above-mentioned earphone body 41 . For example, the battery can be arranged inside the cavity of the rod body 4a. The speaker assembly in the audio module can be arranged inside the cavity of the earplug 4b. When the user puts on the earplugs, he can hear the sound signal from the speaker assembly, so as to realize functions such as playing music and answering/calling for the user.
本申请实施例中，上述磁传感器411可以设置在图4D所示的耳机本体41的耳塞4b或者杆体4a中。例如，如图4A所示，磁传感器411可以设置在耳机本体41的耳塞中。又例如，如图4B所示，磁传感器411可以设置在耳机本体41的杆体中。In the embodiment of the present application, the above-mentioned magnetic sensor 411 may be arranged in the earplug 4b or the rod body 4a of the earphone body 41 shown in FIG. 4D . For example, as shown in FIG. 4A , the magnetic sensor 411 may be disposed in the earplug of the earphone body 41 . For another example, as shown in FIG. 4B , the magnetic sensor 411 may be disposed in the rod body of the earphone body 41 .
进一步的，为了使耳机本体41处于盒内状态和盒外状态时，磁传感器411检测到的磁感应强度的差异更加明显，第一磁体421在耳机盒42中的位置与磁传感器411在耳机本体41中的位置对应。Further, in order to make the difference between the magnetic induction intensity detected by the magnetic sensor 411 more obvious when the earphone body 41 is in the state inside the box and the state outside the box, the position of the first magnet 421 in the earphone box 42 is the same as that of the magnetic sensor 411 in the earphone body 41. corresponding to the position in .
如图4A或4B所示，耳机盒42的收纳腔可以包括第一腔体422和第二腔体423。其中，当耳机本体41收纳于耳机盒42内时，第一腔体422用于收纳耳机本体41的耳塞，第二腔体423用于收纳耳机本体41的杆体。例如，如图4A所示，磁传感器411设置在耳机本体41的耳塞中时，第一磁体421则可以设置在耳机盒42内、靠近耳机盒42的第一腔体422的位置。又例如，如图4B所示，磁传感器411设置在耳机本体41的杆体中时，第一磁体421则可以设置在耳机盒42内、靠近耳机盒42的第二腔体423的位置。As shown in FIG. 4A or 4B , the receiving cavity of the earphone box 42 may include a first cavity 422 and a second cavity 423 . Wherein, when the earphone body 41 is stored in the earphone box 42 , the first cavity 422 is used for accommodating the earplug of the earphone body 41 , and the second cavity 423 is used for accommodating the rod body of the earphone body 41 . For example, as shown in FIG. 4A , when the magnetic sensor 411 is disposed in the earplug of the earphone body 41 , the first magnet 421 can be disposed in the earphone box 42 near the first cavity 422 of the earphone box 42 . For another example, as shown in FIG. 4B , when the magnetic sensor 411 is disposed in the rod body of the earphone body 41 , the first magnet 421 can be disposed in the earphone box 42 near the second cavity 423 of the earphone box 42 .
由上述描述可知：如果耳机本体41处于盒内状态，磁传感器411检测的磁感应强度在第一强度区间；如果耳机本体41处于外状态，磁传感器411检测的磁感应强度在第二强度区间。因此，在磁传感器411检测的磁感应强度由第一强度区间切换至第二强度区间时，则表示该耳机本体41由盒内状态切换为盒外状态，处理器412可以确定耳机本体41出盒。在磁传感器411检测的磁感应强度由第二强度区间切换至第一强度区间时，则表示该耳机本体41由盒外状态切换为盒内状态，处理器412可以确定耳机本体41入盒。It can be seen from the above description that if the earphone body 41 is in the box state, the magnetic induction intensity detected by the magnetic sensor 411 is in the first intensity interval; if the earphone body 41 is in the outer state, the magnetic induction intensity detected by the magnetic sensor 411 is in the second intensity interval. Therefore, when the magnetic induction intensity detected by the magnetic sensor 411 switches from the first intensity interval to the second intensity interval, it means that the earphone body 41 is switched from the in-box state to the out-of-box state, and the processor 412 can determine that the earphone body 41 is out of the box. When the magnetic induction intensity detected by the magnetic sensor 411 switches from the second intensity interval to the first intensity interval, it means that the earphone body 41 is switched from the out-of-box state to the in-box state, and the processor 412 can determine that the earphone body 41 is in the box.
本申请实施例中，耳机本体41可以通过磁传感器411检测耳机本体41周围的磁场的磁感应强度；然后，根据耳机本体41周围的磁场的磁感应强度的变化，来检测耳机本体41的出盒和入盒。其中，根据磁场的磁感应强度的变化检测耳机本体41的出盒和入盒时，检测结果不会因为耳机盒42和耳机本体41的接触接触不良，而导致对无线耳机出盒或入盒的误判。上述检测方式是一种非接触是检测方式，可以提高无线耳机的出入盒检测的准确性。In the embodiment of the present application, the earphone body 41 can detect the magnetic induction intensity of the magnetic field around the earphone body 41 through the magnetic sensor 411; box. Wherein, according to the change of the magnetic induction intensity of the magnetic field, when the box-out and box-in of the earphone body 41 are detected, the detection result will not cause the wireless earphone out of the box or into the box due to poor contact between the earphone box 42 and the earphone body 41. sentenced. The above-mentioned detection method is a non-contact detection method, which can improve the accuracy of detection of the wireless earphone in and out of the box.
本申请实施例这里对上述第一强度区间和第二强度区间的取值进行说明。In this embodiment of the present application, the values of the above-mentioned first intensity interval and the second intensity interval are described here.
在第一种情况下，上述第一强度区间(如[B1，B2])的最小磁感应强度(如B1)可以大于第二强度区间(如[B3，B4])的最大磁感应强度(如B4)。也就是说，耳机本体41处于盒内状态时磁传感器411检测的磁感应强度，大于耳机本体41处于盒外状态时磁传感器411检测的磁感应强度。In the first case, the minimum magnetic induction intensity (such as B1) of the above-mentioned first intensity interval (such as [B1, B2]) may be greater than the maximum magnetic induction intensity (such as B4) of the second intensity interval (such as [B3, B4]) . That is to say, the magnetic induction intensity detected by the magnetic sensor 411 when the earphone body 41 is in the box state is greater than the magnetic induction intensity detected by the magnetic sensor 411 when the earphone body 41 is in the out-of-box state.
在第二种情况下，上述第二强度区间(如[Biii，Biv])的最小磁感应强度(如Biii)大于第一强度区间(如[Bi，Bii])的最大磁感应强度(如Bii)。也就是说，耳机本体41处于盒外状态时磁传感器411检测的磁感应强度，大于耳机本体41处于盒内状态时磁传感器411检测的磁感应强度。In the second case, the minimum magnetic induction intensity (such as Biii) of the above-mentioned second intensity interval (such as [Biii, Biv]) is greater than the maximum magnetic induction intensity (such as Bii) of the first intensity interval (such as [Bi, Bii]). That is to say, the magnetic induction intensity detected by the magnetic sensor 411 when the earphone body 41 is outside the box is greater than the magnetic induction intensity detected by the magnetic sensor 411 when the earphone body 41 is in the box state.
当然，第一强度区间和第二强度区间的取值范围包括但不限于上述[B1，B2]、[B3，B4]、[Bi，Bii]和[Biii，Biv]。例如，第一强度区间可以为(B1，B2)，第二强度区间为(B3，B4)；或者，第一强度区间可以为(Bi，Bii)，第二强度区间为(Biii，Biv)。Of course, the value ranges of the first intensity interval and the second intensity interval include but are not limited to the above-mentioned [B1, B2], [B3, B4], [Bi, Bii] and [Biii, Biv]. For example, the first intensity interval may be (B1, B2), and the second intensity interval may be (B3, B4); or, the first intensity interval may be (Bi, Bii), and the second intensity interval may be (Biii, Biv).
本申请实施例这里对产生上述两种情况的原理进行说明：The embodiment of this application here explains the principles of the above two situations:
由于磁场的磁场强度是一个矢量；因此，多个磁体产生的磁场的磁场强度可能会因为磁场的方向相反而相互抵消，使得多个磁体产生的合磁场的磁场强度小于一个磁体产生的磁场的磁场强度。当然，多个磁体产生的磁场的磁场强度可能会因为磁场的方向相同而相互增强，使得多个磁体产生的合磁场的磁场强度大于一个磁体产生的磁场的磁场强度。Since the magnetic field strength of a magnetic field is a vector; therefore, the magnetic field strengths of the magnetic fields generated by multiple magnets may cancel each other out due to the opposite directions of the magnetic fields, making the magnetic field strength of the combined magnetic field generated by multiple magnets smaller than that of the magnetic field generated by one magnet strength. Of course, the magnetic field strengths of the magnetic fields generated by multiple magnets may mutually reinforce each other due to the same direction of the magnetic fields, so that the magnetic field strength of the combined magnetic field generated by multiple magnets is greater than the magnetic field strength of the magnetic field generated by one magnet.
由此可见，上述第一磁场(即处于盒内状态时，耳机本体41周围的磁场)的磁场强度，可能会大于第二磁场(即处于盒外状态时，耳机本体41周围的磁场)的磁场强度，也可能会小于第二磁场的磁场强度。其中，第一磁场和第二磁场的磁场强度的大小决定于耳机盒42和耳机本体41中各个磁体的磁场的磁矢量的大小和方向。It can be seen that the magnetic field strength of the above-mentioned first magnetic field (that is, the magnetic field around the earphone body 41 when it is in the state inside the box) may be greater than the magnetic field of the second magnetic field (that is, the magnetic field around the earphone body 41 when it is in the state outside the box) The strength may also be smaller than the magnetic field strength of the second magnetic field. Wherein, the magnitudes of the magnetic field strengths of the first magnetic field and the second magnetic field are determined by the magnitude and direction of the magnetic vectors of the magnetic fields of the respective magnets in the earphone box 42 and the earphone body 41 .
但是，可以明确的是：上述第一磁场的磁场强度与第二磁场的磁场强度不同。从而，磁传感器411在第一磁场检测到的磁感应强度与磁传感器411在第二磁场检测到的磁感应强度也不同。也就是说，上述第一强度区间与第二强度区间没有交集。However, it is clear that the magnetic field strength of the first magnetic field is different from the magnetic field strength of the second magnetic field. Therefore, the magnetic induction intensity detected by the magnetic sensor 411 in the first magnetic field is also different from the magnetic induction intensity detected by the magnetic sensor 411 in the second magnetic field. That is to say, there is no intersection between the above-mentioned first intensity interval and the second intensity interval.
具体的，在第一磁场的磁场强度大于第二磁场的磁场强度的情况下，上述第一强度区间和第二强度区间符合上述第一种情况。也就是说，第一强度区间的最小磁感应强度大于第二强度区间的最大磁感应强度。Specifically, in the case where the magnetic field strength of the first magnetic field is greater than the magnetic field strength of the second magnetic field, the above-mentioned first strength interval and the second strength interval conform to the above-mentioned first situation. That is to say, the minimum magnetic induction in the first intensity range is greater than the maximum magnetic induction in the second intensity range.
在第一磁场的磁场强度小于第二磁场的磁场强度的情况下，上述第一强度区间和第二强度区间符合上述第二种情况。也就是说，第二强度区间的最小磁感应强度大于第一强度区间的最大磁感应强度。In the case that the magnetic field strength of the first magnetic field is smaller than the magnetic field strength of the second magnetic field, the above-mentioned first strength interval and the second strength interval conform to the above-mentioned second situation. That is to say, the minimum magnetic induction in the second intensity range is greater than the maximum magnetic induction in the first intensity range.
需要说明的是，由于受到耳机盒42中设置的第一磁体421产生的磁场的影响，上述第一磁场的磁场强度与第二磁场的磁场强度的差异较大。从而，磁传感器411在上述第一磁场检测到的磁感应强度与磁传感器411在第二磁场检测到的磁感应强度也会存在较大差异。如此，在上述第一种情况下，第一强度区间的最小磁感应强度与第二强度区间的最大磁感应强度的差值较大。在第二种情况下，第二强度区间的最小磁感应强度与第一强度区间的最大磁感应强度的差值较大。这样，有利于提高无线耳机的出入盒检测的准确性。It should be noted that, due to the influence of the magnetic field generated by the first magnet 421 disposed in the earphone box 42 , the magnetic field strength of the first magnetic field is quite different from the magnetic field strength of the second magnetic field. Therefore, the magnetic induction intensity detected by the magnetic sensor 411 in the first magnetic field and the magnetic induction intensity detected by the magnetic sensor 411 in the second magnetic field also have a large difference. Thus, in the first case above, the difference between the minimum magnetic induction in the first intensity interval and the maximum magnetic induction in the second intensity interval is relatively large. In the second case, the difference between the minimum magnetic induction in the second intensity interval and the maximum magnetic induction in the first intensity interval is relatively large. In this way, it is beneficial to improve the accuracy of detection of the wireless earphone entering and exiting the box.

在该实施例中，磁传感器411可以用于：检测耳机主体41周围的磁场的磁感应强度；如果检测到磁感应强度在第一强度区间，向处理器412输出第一信号；如果检测到磁感应强度在第二强度区间，向处理器412输出第二信号。In this embodiment, the magnetic sensor 411 can be used to: detect the magnetic induction intensity of the magnetic field around the earphone main body 41; if it is detected that the magnetic induction intensity is in the first intensity interval, output the first signal to the processor 412; if it is detected that the magnetic induction intensity is in the first intensity interval In the second intensity interval, a second signal is output to the processor 412 .
处理器412可以用于：响应于磁传感器411传输的信号由第一信号变为第二信号，确定耳机本体41出盒；响应于磁传感器411传输的信号由第二信号变为第一信号，确定无线耳机入盒。The processor 412 may be configured to: in response to the signal transmitted by the magnetic sensor 411 changing from the first signal to the second signal, determine that the earphone body 41 is out of the box; in response to the signal transmitted by the magnetic sensor 411 changing from the second signal to the first signal, Make sure the wireless earphones are in the box.

Alternatively, the first signal is at low level and the second signal is at high level. In the following embodiments, the solutions of the embodiments of the present application will be described by taking the first signal at a low level and the second signal at a high level as an example.
示例性的，以下结合上述第一种情况和第二种情况，通过实现方式(1)和实现方式(2)，对第一类磁传感器(如霍尔传感器)与处理器412配合实现耳机本体41的出盒和入盒检测原理进行说明。Exemplarily, the first type of magnetic sensor (such as a Hall sensor) and the processor 412 cooperate to realize the earphone body through the implementation (1) and the implementation (2) below in combination with the above-mentioned first case and the second case 41 box out and box in detection principles will be described.
在实现方式(1)中，结合上述第一种情况，对耳机本体41的出盒和入盒检测原理进行说明。In the implementation mode (1), the principle of box-out and box-in detection of the earphone body 41 will be described in conjunction with the above first case.
在上述第一种情况中，假设第一强度区间为[B1，B2]，第二强度区间为[B3，B4]。如图5A或图5B所示，第一强度区间[B1，B2]的最小磁感应强度B1大于第二强度区间[B3，B4]的最大磁感应强度B4。上述第一磁场(即处于盒内状态时，耳机本体41周围的磁场)的磁场强度大于第二磁场(即处于盒外状态时，耳机本体41周围的磁场)的磁场强度。In the first case above, it is assumed that the first intensity interval is [B1, B2] and the second intensity interval is [B3, B4]. As shown in FIG. 5A or FIG. 5B , the minimum magnetic induction intensity B1 of the first intensity interval [B1, B2] is greater than the maximum magnetic induction intensity B4 of the second intensity interval [B3, B4]. The magnetic field strength of the first magnetic field (that is, the magnetic field around the earphone body 41 when it is in the box) is greater than the magnetic field strength of the second magnetic field (that is, the magnetic field around the earphone body 41 when it is out of the box).
请参考图5A，其示出耳机本体41出盒过程中，磁传感器411向处理器412传输的信号与磁感应强度变化示意图。Please refer to FIG. 5A , which shows a schematic diagram of the signal transmitted from the magnetic sensor 411 to the processor 412 and the change of the magnetic induction intensity during the process of the earphone body 41 being out of the box.
假设耳机本体41处于盒内状态。如图5A所示，磁传感器411检测的磁感应强度在第一强度区间[B1，B2]内，磁传感器411可以向处理器输出低电平(即第一信号)。Assume that the earphone body 41 is in a case. As shown in FIG. 5A , the magnetic induction detected by the magnetic sensor 411 is within the first intensity interval [B1, B2], and the magnetic sensor 411 may output a low level (ie, a first signal) to the processor.
可以理解，在耳机本体41出盒的过程中，可能会因为耳机本体41还未完全从耳机盒42的收纳腔中取出，而使得磁传感器411检测的磁感应强度在图5A所示的(B4，B1)内。基于这种情况，为了避免耳机本体41检测到耳机本体41频繁的出盒/入盒，磁传感器411还可以用于：在检测到磁感应强度在第一强度区间[B1，B2]内之后，如果检测到磁感应强度小于第一强度区域[B1，B2]的最小磁感应强度B1、但大于第二强度区域[B3，B4]的最大磁感应强度B4，则向处理器412输出低电平(即第一信号)。It can be understood that during the process of removing the earphone body 41 from the box, the magnetic induction intensity detected by the magnetic sensor 411 may be in the range (B4, within B1). Based on this situation, in order to prevent the earphone body 41 from detecting frequent out-of-box/in-box of the earphone body 41, the magnetic sensor 411 can also be used to: after detecting that the magnetic induction intensity is within the first intensity interval [B1, B2], if Detect that the magnetic induction intensity is less than the minimum magnetic induction intensity B1 of the first intensity area [B1, B2], but greater than the maximum magnetic induction intensity B4 of the second intensity area [B3, B4], then output a low level to the processor 412 (i.e. the first Signal).
例如，如图5A所示，磁传感器411在检测到磁感应强度在[B1，B2]之后，如果检测到磁感应强度在(B4，B1)内，仍然可以向处理器412输出低电平。For example, as shown in FIG. 5A , after the magnetic sensor 411 detects that the magnetic induction is within [B1, B2], if it detects that the magnetic induction is within (B4, B1), it may still output a low level to the processor 412.
耳机本体41出盒(即耳机本体41由盒内状态切换为盒外状态)之后，如图5A所示，磁传感器411检测的磁感应强度在第二强度区间[B3，B4]内，磁传感器411可以向处理器412输出高电平(即第二信号)。After the earphone body 41 is out of the box (that is, the earphone body 41 is switched from the state inside the box to the state outside the box), as shown in FIG. 5A , the magnetic induction intensity detected by the magnetic sensor 411 is within the second intensity interval [B3, B4]. A high level (ie, the second signal) may be output to the processor 412 .
综上所述，如图5A所示，在耳机本体41出盒(即由盒内状态切换为盒外状态)过程中，磁传感器411向处理器412传输的信号由低电平变为高电平。处理器412具体可以用于：响应于磁传感器411传输的信号由低电平变为高电平，确定耳机本体41出盒。In summary, as shown in FIG. 5A , during the process of the headphone body 41 being out of the box (that is, switching from the state inside the box to the state outside the box), the signal transmitted from the magnetic sensor 411 to the processor 412 changes from a low level to a high level. flat. The processor 412 may be specifically configured to: determine that the earphone body 41 is out of the box in response to the signal transmitted by the magnetic sensor 411 changing from a low level to a high level.
示例性的，处理器412可以实时监测磁传感器411传输的信号；当检测到磁传感器411传输的信号由低电平变为高电平时，可以确定耳机本体41出盒。或者，处理器412可以根据第一中断信号，确定耳机本体41出盒。其中，该第一中断信号可以是在磁传感器411传输的信号由低电平变为高电平时产生的。Exemplarily, the processor 412 can monitor the signal transmitted by the magnetic sensor 411 in real time; when it detects that the signal transmitted by the magnetic sensor 411 changes from a low level to a high level, it can determine that the earphone body 41 is out of the box. Alternatively, the processor 412 may determine that the earphone body 41 is out of the box according to the first interrupt signal. Wherein, the first interrupt signal may be generated when the signal transmitted by the magnetic sensor 411 changes from a low level to a high level.

As shown in FIG. 5B , the magnetic induction detected by the magnetic sensor 411 is within the second intensity interval [ B3 , B4 ], and the magnetic sensor 411 may output a high level (ie, a second signal) to the processor 412 .
可以理解，在耳机本体41入盒的过程中，可能会因为耳机本体41还未完全进入耳机盒42的收纳腔，而使得磁传感器411检测的磁感应强度在图5B所示的(B4，B1)内。基于这种情况，为了避免耳机本体41检测到耳机本体41频繁的出盒/入盒，磁传感器411还可以用于：在检测到磁感应强度在第二强度区间[B3，B4]内之后，如果检测到磁感应强度大于第二强度区间[B3，B4]的最大磁感应强度B4、但小于第一强度区域[B1，B2]的最小磁感应强度B1，则向处理器412输出高电平(即第二信号)。It can be understood that during the process of putting the earphone body 41 into the box, the magnetic induction intensity detected by the magnetic sensor 411 may be at (B4, B1) shown in FIG. Inside. Based on this situation, in order to prevent the earphone body 41 from detecting frequent out-of-box/in-box of the earphone body 41, the magnetic sensor 411 can also be used to: after detecting that the magnetic induction intensity is within the second intensity interval [B3, B4], if Detect that the magnetic induction intensity is greater than the maximum magnetic induction intensity B4 of the second intensity interval [B3, B4], but less than the minimum magnetic induction intensity B1 of the first intensity area [B1, B2], then output a high level to the processor 412 (i.e. the second Signal).
例如，如图5B所示，磁传感器411在检测到磁感应强度在[B3，B4]之后，如果检测到磁感应强度在(B4，B1)内，仍然可以向处理器412输出高电平。For example, as shown in FIG. 5B , after the magnetic sensor 411 detects that the magnetic induction is within [B3, B4], if it detects that the magnetic induction is within (B4, B1), it may still output a high level to the processor 412.
耳机本体41入盒(即耳机本体41由盒外状态切换为盒内状态)之后，如图5B所示，磁传感器411检测的磁感应强度在第一强度区间[B1，B2]内，磁传感器411可以向处理器输出低电平(即第一信号)。After the earphone body 41 is put into the box (that is, the earphone body 41 is switched from the state outside the box to the state inside the box), as shown in FIG. 5B , the magnetic induction intensity detected by the magnetic sensor 411 is within the first intensity interval [B1, B2]. A low level (ie, the first signal) may be output to the processor.
综上所述，如图5B所示，在耳机本体41入盒(即由盒外状态切换为盒内状态)过程中，磁传感器411向处理器412传输的信号由高电平变为低电平。处理器412具体可以用于：响应于磁传感器411传输的信号由高电平变为低电平，确定耳机本体41入盒。In summary, as shown in FIG. 5B , during the process of putting the earphone body 41 into the box (that is, switching from the state outside the box to the state inside the box), the signal transmitted from the magnetic sensor 411 to the processor 412 changes from a high level to a low level. flat. The processor 412 may specifically be configured to determine that the headphone body 41 is in the box in response to the signal transmitted by the magnetic sensor 411 changing from a high level to a low level.

Alternatively, the processor 412 may determine that the earphone body 41 is in the box according to the second interrupt signal. Wherein, the second interrupt signal may be generated when the signal transmitted by the magnetic sensor 411 changes from a high level to a low level.
需要说明的是，上述实现方式(1)中，第二强度区间[B3，B4]中的B4和第一强度区间[B1，B2]中的B1可以是上述霍尔传感器的两个磁感应强度门限，B1>B4。上述B2可以为大于B1的任一磁感器强度，上述B3可以为小于B4的任一磁感器强度。例如，B3可以为零，B2可以为无穷大。It should be noted that, in the above implementation (1), B4 in the second intensity interval [B3, B4] and B1 in the first intensity interval [B1, B2] can be the two magnetic induction intensity thresholds of the Hall sensor , B1>B4. The above-mentioned B2 can be any magnetic sensor strength greater than B1, and the above-mentioned B3 can be any magnetic sensor strength smaller than B4. For example, B3 can be zero and B2 can be infinity.
可以理解，在实际产品中，霍尔传感器判断磁感应强度时，可以只使用上述B4和B1。具体的，霍尔传感器可以在检测的磁感应强度大于B1时，向处理器412输出低电平(即第一信号)。如果霍尔传感器在检测到磁感应强度大于B1之后，检测到磁感应强度在(B4，B1)内，如图5A所示，可以输出低电平(即第一信号)。It can be understood that, in actual products, when the Hall sensor judges the magnetic induction intensity, only the above-mentioned B4 and B1 can be used. Specifically, the Hall sensor may output a low level (that is, the first signal) to the processor 412 when the detected magnetic induction intensity is greater than B1. If the Hall sensor detects that the magnetic induction is within (B4, B1) after detecting that the magnetic induction is greater than B1, as shown in FIG. 5A, it may output a low level (ie, the first signal).
霍尔传感器还可以在检测的磁感应强度小于B4时，向处理器412输出高电平(即第二信号)。如果霍尔传感器在检测到磁感应强度小于B4之后，检测到磁感应强度在(B4，B1)内，如图5B所示，可以输出高电平(即第二信号)。The Hall sensor can also output a high level (that is, a second signal) to the processor 412 when the detected magnetic induction intensity is less than B4. If the Hall sensor detects that the magnetic induction is within (B4, B1) after detecting that the magnetic induction is less than B4, as shown in FIG. 5B, it may output a high level (ie, the second signal).
在实现方式(2)中，结合上述第二种情况，对耳机本体41的出盒和入盒检测原理进行说明。In the implementation mode (2), in conjunction with the second case above, the principle of box-out and box-in detection of the earphone body 41 will be described.
在上述第二种情况中，假设第一强度区间为[Bi，Bii]，第二强度区间为[Biii，Biv]。如图6A或图6B所示，第二强度区间[Biii，Biv]的最小磁感应强度Biii大于第一强度区间[Bi，Bii]的最大磁感应强度Bii。上述第一磁场(即处于盒内状态时，耳机本体41周围的磁场)的磁场强度小于第二磁场(即处于盒外状态时，耳机本体41周围的磁场)的磁场强度。In the second case above, it is assumed that the first intensity interval is [Bi, Bii] and the second intensity interval is [Biii, Biv]. As shown in FIG. 6A or FIG. 6B , the minimum magnetic induction Biii of the second intensity interval [Biii, Biv] is greater than the maximum magnetic induction Bii of the first intensity interval [Bi, Bii]. The magnetic field strength of the first magnetic field (that is, the magnetic field around the earphone body 41 when it is inside the box) is smaller than the magnetic field strength of the second magnetic field (that is, the magnetic field around the earphone body 41 when it is out of the box).

As shown in FIG. 6A , the magnetic induction detected by the magnetic sensor 411 is within the second intensity interval [Biii, Biv], and the magnetic sensor 411 may output a high level (ie, a second signal) to the processor 412 .
可以理解，在耳机本体41入盒的过程中，可能会因为耳机本体41还未完全进入耳机盒42的收纳腔，而使得磁传感器411检测的磁感应强度在图6A所示的(Bii，Biii)内。基于这种情况，为了避免耳机本体41检测到耳机本体41频繁的出盒/入盒，磁传感器411还可以用于：在检测到磁感应强度在第二强度区间[Biii，Biv]内之后，如果检测到磁感应强度小于第二强度区间[Biii，Biv]的最小磁感应强度Biii、但大于第一强度区域[Bi，Bii]的最大磁感应强度Bii，则向处理器412输出高电平(即第二信号)。It can be understood that during the process of putting the earphone body 41 into the box, the magnetic induction intensity detected by the magnetic sensor 411 may be within (Bii, Biii) shown in FIG. Inside. Based on this situation, in order to prevent the earphone body 41 from detecting frequent out-of-box/in-box of the earphone body 41, the magnetic sensor 411 can also be used for: after detecting that the magnetic induction intensity is within the second intensity interval [Biii, Biv], if Detect that the magnetic induction intensity is less than the minimum magnetic induction intensity Biii of the second intensity interval [Biii, Biv], but greater than the maximum magnetic induction intensity Bii of the first intensity area [Bi, Bii], then output a high level to the processor 412 (i.e. the second Signal).
例如，如图6A所示，磁传感器411在检测到磁感应强度在[Biii，Biv]之后，如果检测到磁感应强度在(Bii，Biii)内，仍然可以向处理器412输出高电平(即第一信号)。For example, as shown in FIG. 6A, after the magnetic sensor 411 detects that the magnetic induction intensity is within [Biii, Biv], if it detects that the magnetic induction intensity is within (Bii, Biii), it can still output a high level to the processor 412 (that is, the first a signal).
耳机本体41入盒(即耳机本体41由盒外状态切换为盒内状态)之后，如图6A所示，磁传感器411检测的磁感应强度在第一强度区间[Bi，Bii]内，磁传感器411可以向处理器412输出低电平(即第一信号)。After the earphone body 41 is put into the box (that is, the earphone body 41 is switched from the state outside the box to the state inside the box), as shown in FIG. 6A , the magnetic induction intensity detected by the magnetic sensor 411 is within the first intensity interval [Bi, Bii]. A low level (ie, the first signal) may be output to the processor 412 .
综上所述，如图6A所示，在耳机本体41入盒(即由盒外状态切换为盒内状态)过程中，磁传感器411向处理器412传输的信号由高电平变为低电平。处理器412具体可以用于：响应于磁传感器411传输的信号由高电平变为低电平，确定耳机本体41入盒。To sum up, as shown in FIG. 6A, during the process of putting the earphone body 41 into the box (that is, switching from the state outside the box to the state inside the box), the signal transmitted from the magnetic sensor 411 to the processor 412 changes from a high level to a low level. flat. The processor 412 may specifically be configured to determine that the headphone body 41 is in the box in response to the signal transmitted by the magnetic sensor 411 changing from a high level to a low level.
请参考图6B，其示出耳机本体41出盒过程中，磁传感器411向处理器412传输的信号与磁感应强度变化示意图。Please refer to FIG. 6B , which shows a schematic diagram of the signal transmitted from the magnetic sensor 411 to the processor 412 and the change of the magnetic induction intensity during the process of the earphone body 41 being out of the box.
假设耳机本体41处于盒内状态。如图6B所示，磁传感器411检测的磁感应强度在第一强度区间[Bi，Bii内，磁传感器411可以向处理器输出低电平(即第一信号)。Assume that the earphone body 41 is in a case. As shown in FIG. 6B , the magnetic induction detected by the magnetic sensor 411 is within the first intensity interval [Bi, Bii, and the magnetic sensor 411 may output a low level (ie, a first signal) to the processor.
可以理解，在耳机本体41出盒的过程中，可能会因为耳机本体41还未完全从耳机盒42的收纳腔中取出，而使得磁传感器411检测的磁感应强度在图6B所示的(Bii，Biii)内。基于这种情况，为了避免耳机本体41检测到耳机本体41频繁的出盒/入盒，磁传感器411还可以用于：在检测到磁感应强度在第一强度区间[Bi，Bii]内之后，如果检测到磁感应强度大于第一强度区域[Bi，Bii]的最大磁感应强度Bii、但小于第二强度区域[Biii，Biv]的最小磁感应强度Biii，则向处理器412输出低电平(即第一信号)。It can be understood that during the process of removing the earphone body 41 from the box, the magnetic induction intensity detected by the magnetic sensor 411 may not be completely taken out from the storage chamber of the earphone box 42 because the earphone body 41 is not completely removed from the box (Bii, Biii). Based on this situation, in order to prevent the earphone body 41 from detecting frequent out-of-box/in-box of the earphone body 41, the magnetic sensor 411 can also be used: after detecting that the magnetic induction intensity is within the first intensity interval [Bi, Bii], if Detect that the magnetic induction intensity is greater than the maximum magnetic induction intensity Bii of the first intensity area [Bi, Bii], but less than the minimum magnetic induction intensity Biii of the second intensity area [Biii, Biv], then output a low level to the processor 412 (i.e. the first Signal).
例如，如图6B所示，磁传感器411在检测到磁感应强度在[Bi，Bii]之后，如果检测到磁感应强度在(Bii，Biii)内，仍然可以向处理器412输出低电平(即第一信号)。For example, as shown in FIG. 6B , after the magnetic sensor 411 detects that the magnetic induction intensity is within [Bi, Bii], if it detects that the magnetic induction intensity is within (Bii, Biii), it can still output a low level to the processor 412 (that is, the first a signal).

A high level (ie, the second signal) may be output to the processor 412 .
综上所述，如图6B所示，在耳机本体41出盒(即由盒内状态切换为盒外状态)过程中，磁传感器411向处理器412传输的信号由低电平变为高电平。处理器412具体可以用于：响应于磁传感器411传输的信号由低电平变为高电平，确定耳机本体41出盒。In summary, as shown in FIG. 6B , during the process of the headphone body 41 being out of the box (that is, switching from the state inside the box to the state outside the box), the signal transmitted from the magnetic sensor 411 to the processor 412 changes from a low level to a high level. flat. The processor 412 may be specifically configured to: determine that the earphone body 41 is out of the box in response to the signal transmitted by the magnetic sensor 411 changing from a low level to a high level.
需要说明的是，上述实现方式(2)中，第二强度区间[Biii，Biv]中的Biii和第一强度区间[Bi，Bii]中的Bii可以是第一类磁传感器(如霍尔传感器)的两个磁感应强度门限，Biii>Bii。上述Bi可以为小于Bii的任一磁感器强度，上述Biv可以为大于Biii的任一磁感器强度。例如，Bi可以为零，Biv可以为无穷大。It should be noted that, in the above implementation (2), Biii in the second intensity interval [Biii, Biv] and Bii in the first intensity interval [Bi, Bii] can be the first type of magnetic sensor (such as a Hall sensor ), Biii>Bii. The above-mentioned Bi can be any magnetic sensor strength smaller than Bii, and the above-mentioned Biv can be any magnetic sensor strength larger than Biii. For example, Bi can be zero and Biv can be infinite.
可以理解，在实际产品中，霍尔传感器判断检测的磁感应强度时，可以仅使用上述Bii和Biii。具体的，霍尔传感器可以在检测的磁感应强度大于Biii时，向处理器412输出高电平(即第二信号)。如果霍尔传感器在检测到磁感应强度大于Biii之后，检测到磁感应强度在(Bii，Biii)内，如图6A所示，可以输出高电平(即第二信号)。It can be understood that, in actual products, when the Hall sensor judges the detected magnetic induction intensity, only Bii and Biii above can be used. Specifically, the Hall sensor may output a high level (that is, the second signal) to the processor 412 when the detected magnetic induction intensity is greater than Biii. If the Hall sensor detects that the magnetic induction is within (Bii, Biii) after detecting that the magnetic induction is greater than Biii, as shown in FIG. 6A , it may output a high level (ie, the second signal).
霍尔传感器可以在检测的磁感应强度小于Bii时，向处理器412输出低电平(即第二信号)。如果霍尔传感器在检测到磁感应强度小于Bii之后，检测到磁感应强度在(Bii，Biii)内，如图6B所示，可以输出低电平(即第一信号)。The Hall sensor may output a low level (that is, a second signal) to the processor 412 when the detected magnetic induction intensity is less than Bii. If the Hall sensor detects that the magnetic induction is within (Bii, Biii) after detecting that the magnetic induction is less than Bii, as shown in FIG. 6B , it may output a low level (ie, the first signal).

在该实施例中，磁传感器411可以用于：检测耳机本体41周围的磁场的磁感应强度；向处理器412传输检测的磁感应强度。In this embodiment, the magnetic sensor 411 can be used to: detect the magnetic induction intensity of the magnetic field around the earphone body 41 ; and transmit the detected magnetic induction intensity to the processor 412 .
处理器412可以用于：在磁传感器411检测的磁感应强度由第一强度区间切换至第二强度区间时，确定耳机本体41出盒；在磁传感器411检测的磁感应强度由第二强度区间切换至第一强度区间时，确定耳机本体41入盒。The processor 412 can be used to: when the magnetic induction intensity detected by the magnetic sensor 411 is switched from the first intensity interval to the second intensity interval, determine that the earphone body 41 is out of the box; when the magnetic induction intensity detected by the magnetic sensor 411 is switched from the second intensity interval to In the first intensity interval, it is determined that the earphone body 41 is in the box.
示例性的，以下结合上述第一种情况和第二种情况，通过实现方式(a)和实现方式(b)，对第二类磁传感器(如磁力计)与处理器412配合实现耳机本体41的出盒和入盒检测原理进行说明。Exemplarily, in combination with the first case and the second case above, through the implementation (a) and the implementation (b), the second type of magnetic sensor (such as a magnetometer) cooperates with the processor 412 to realize the earphone body 41 The principle of box-out and box-in detection will be described.
在实现方式(a)中，结合上述第一种情况，对耳机本体41的出盒和入盒检测原理进行说明。In the implementation mode (a), the principle of box-out and box-in detection of the earphone body 41 will be described in combination with the first case above.
在上述第一种情况中，假设第一强度区间为[B1，B2]，第二强度区间为[B3，B4]。如图7A所示，第一强度区间[B1，B2]的最小磁感应强度B1大于第二强度区间[B3，B4]的最大磁感应强度B4。上述第一磁场(即处于盒内状态时，耳机本体41周围的磁场)的磁场强度大于第二磁场(即处于盒外状态时，耳机本体41周围的磁场)的磁场强度。In the first case above, it is assumed that the first intensity interval is [B1, B2] and the second intensity interval is [B3, B4]. As shown in FIG. 7A , the minimum magnetic induction intensity B1 of the first intensity interval [ B1 , B2 ] is greater than the maximum magnetic induction intensity B4 of the second intensity interval [ B3 , B4 ]. The magnetic field strength of the first magnetic field (that is, the magnetic field around the earphone body 41 when it is in the box) is greater than the magnetic field strength of the second magnetic field (that is, the magnetic field around the earphone body 41 when it is out of the box).
首先，本申请实施例结合图7A对耳机本体41的出盒过程进行说明：First, the embodiment of the present application describes the out-of-box process of the earphone body 41 with reference to FIG. 7A:
如图7A所示，在t1时刻-t3时刻这段时间，磁传感器检测到的磁感应强度在第一强度区间[B1，B2]内，处理器412可以确定耳机本体41处于盒内状态。假设从图7A所示的t2时刻开始，用户从耳机盒42中取出耳机本体41。由于第二磁场的磁场强度小于第一磁场的磁场强度；因此，用户从耳机盒42中取出耳机本体41的过程中，磁传感器411检测到的磁感应强度会变小。例如，如图7A所示，从t2时刻-t4时刻这段时间内，磁传感器411检测到的磁感应强度逐渐变小。As shown in FIG. 7A , during the period from time t1 to time t3 , the magnetic induction detected by the magnetic sensor is within the first intensity interval [B1, B2], and the processor 412 can determine that the earphone body 41 is in the box. Assume that the user takes out the earphone body 41 from the earphone box 42 from time t2 shown in FIG. 7A . Since the magnetic field intensity of the second magnetic field is smaller than that of the first magnetic field; therefore, when the user takes out the earphone body 41 from the earphone box 42, the magnetic induction intensity detected by the magnetic sensor 411 will become smaller. For example, as shown in FIG. 7A , during the period from time t2 to time t4 , the magnetic induction detected by the magnetic sensor 411 gradually decreases.
本申请实施例中，在磁传感器411检测的磁感应强度由第一强度区域[B1，B2]切换至第三强度区间(如图7A所示的(B4，B1))时，处理器412可以确定耳机本体41处于盒内状态。例如，如图7A所示，在t3时刻-t4时刻这段时间，磁传感器411检测到的磁感应强度在(B4，B1)内，处理器412可以确定耳机本体41处于盒内状态。In the embodiment of the present application, when the magnetic induction intensity detected by the magnetic sensor 411 is switched from the first intensity range [B1, B2] to the third intensity range ((B4, B1) as shown in FIG. 7A ), the processor 412 may determine that The earphone body 41 is in the box state. For example, as shown in FIG. 7A, during the period from time t3 to time t4, the magnetic induction intensity detected by the magnetic sensor 411 is within (B4, B1), and the processor 412 can determine that the earphone body 41 is in the box state.
其中，用户从耳机盒42中取出耳机本体41后，从t4时刻开始(如t4时刻-t5时刻)，磁传感器411检测到的磁感应强度在第二强度区间[B3，B4]内，处理器412可以确定耳机本体41处于盒外状态。Wherein, after the user takes out the earphone body 41 from the earphone box 42, from time t4 (such as time t4-time t5), the magnetic induction intensity detected by the magnetic sensor 411 is within the second intensity interval [B3, B4], and the processor 412 It can be determined that the earphone body 41 is in an out-of-box state.
如图7A所示，从t2时刻开始截止t4时刻，磁传感器411检测到的磁感应强度从第一强度区域[B1，B2]切换至第二强度区间[B3，B4]。处理器412响应于磁传感器411检测的磁感应强度从第一强度区域[B1，B2]切换至第二强度区间[B3，B4]，可以确定耳机本体41出盒。即耳机本体41由盒内状态切换为盒外状态。As shown in FIG. 7A , from time t2 to time t4 , the magnetic induction intensity detected by the magnetic sensor 411 is switched from the first intensity range [ B1 , B2 ] to the second intensity range [ B3 , B4 ]. The processor 412 may determine that the earphone body 41 is out of the box in response to the magnetic induction detected by the magnetic sensor 411 switching from the first intensity range [B1, B2] to the second intensity range [B3, B4]. That is, the earphone body 41 is switched from the state inside the box to the state outside the box.
其次，本申请实施例结合图7A对耳机本体41的入盒过程进行说明：Secondly, the embodiment of the present application describes the box-entry process of the earphone body 41 in conjunction with FIG. 7A:
如图7A所示，在t4时刻-t6时刻这段时间，磁传感器检测到的磁感应强度在第二强度区间[B3，B4]内，处理器412可以确定耳机本体41处于盒外状态。假设从图7A所示的t5时刻开始，用户将耳机本体41放入耳机盒42。由于第一磁场的磁场强度大于第二磁场的磁场强度；因此，用户将耳机本体41放入耳机盒42的过程中，磁传感器411检测到的磁感应强度会变大。例如，如图7A所示，从t5时刻-t7时刻这段时间内，磁传感器411检测到的磁感应强度逐渐变大。As shown in FIG. 7A, during the period from time t4 to time t6, the magnetic induction detected by the magnetic sensor is within the second intensity range [B3, B4], and the processor 412 can determine that the earphone body 41 is in the out-of-box state. Assume that the user puts the earphone body 41 into the earphone box 42 from time t5 shown in FIG. 7A . Since the magnetic field strength of the first magnetic field is greater than that of the second magnetic field; therefore, when the user puts the earphone body 41 into the earphone box 42 , the magnetic induction intensity detected by the magnetic sensor 411 will become larger. For example, as shown in FIG. 7A , during the period from time t5 to time t7 , the magnetic induction detected by the magnetic sensor 411 gradually increases.
本申请实施例中，在磁传感器411检测的磁感应强度由第二强度区域[B3，B4]切换至第三强度区间(如图7A所示的(B4，B1))时，处理器412可以确定耳机本体41处于盒外状态。例如，如图7A所示，在t6时刻-t7时刻这段时间，磁传感器411检测到的磁感应强度在(B4，B1)内，处理器412可以确定耳机本体41处于盒外状态。在本申请实施例中，第三强度区间与第二强度区间没有交集，且第三强度区间与第一强度区间没有交集。例如，(B4，B1)与[B3，B4]没有交集，且(B4，B1)与[B1，B2]没有交集。In the embodiment of the present application, when the magnetic induction intensity detected by the magnetic sensor 411 is switched from the second intensity range [B3, B4] to the third intensity range (as shown in FIG. 7A (B4, B1)), the processor 412 may determine that The earphone body 41 is in an out-of-box state. For example, as shown in FIG. 7A , during the period from time t6 to time t7, the magnetic induction intensity detected by the magnetic sensor 411 is within (B4, B1), and the processor 412 can determine that the earphone body 41 is in the out-of-box state. In the embodiment of the present application, there is no intersection between the third intensity interval and the second intensity interval, and there is no intersection between the third intensity interval and the first intensity interval. For example, (B4, B1) has no intersection with [B3, B4], and (B4, B1) has no intersection with [B1, B2].
其中，用户将耳机本体41放入耳机盒42后，从t7时刻开始，磁传感器411检测到的磁感应强度在第一强度区间[B1，B2]内，处理器412可以确定耳机本体41处于盒内状态。Wherein, after the user puts the earphone body 41 into the earphone box 42, from time t7, the magnetic induction intensity detected by the magnetic sensor 411 is within the first intensity interval [B1, B2], and the processor 412 can determine that the earphone body 41 is in the box state.
如图7A所示，从t5时刻开始到t7时刻，磁传感器411检测到的磁感应强度第二强度区间[B3，B4]切换至第一强度区域[B1，B2]。处理器412响应于磁传感器411检测的磁感应强度从第二强度区间[B3，B4]切换至第一强度区域[B1，B2]，可以确定耳机本体41入盒。即耳机本体41由盒外状态切换为盒内状态。As shown in FIG. 7A , from time t5 to time t7 , the magnetic induction detected by the magnetic sensor 411 switches from the second intensity range [ B3 , B4 ] to the first intensity range [ B1 , B2 ]. The processor 412 may determine that the headphone body 41 is in the box in response to the magnetic induction detected by the magnetic sensor 411 switching from the second intensity range [B3, B4] to the first intensity range [B1, B2]. That is, the earphone body 41 is switched from the state outside the box to the state inside the box.
需要说明的是，上述实现方式(a)中，第二强度区间[B3，B4]中的B4和B3，第一强度区间[B1，B2]中的B1和B2可以是通过软件设置的。例如，耳机本体41可以统计耳机本体41处于盒内状态时磁传感器411检测到的磁感应强度，设置上述B1和B2。耳机本体41可以通过多次统计，得到耳机本体41处于盒内状态时的磁感应强度的最小值和最大值，并将该最小值设置为B1，最大值设置为B2。或者，B2可以为无穷大。It should be noted that, in the above implementation (a), B4 and B3 in the second intensity interval [B3, B4], and B1 and B2 in the first intensity interval [B1, B2] may be set by software. For example, the earphone body 41 can count the magnetic induction intensity detected by the magnetic sensor 411 when the earphone body 41 is in the box state, and set the above-mentioned B1 and B2. The earphone body 41 can obtain the minimum value and maximum value of the magnetic induction intensity when the earphone body 41 is in the box state through multiple statistics, and set the minimum value as B1 and the maximum value as B2. Alternatively, B2 can be infinite.
耳机本体41可以统计耳机本体41处于盒外状态时磁传感器411检测到的磁感应强度，设置上述B4。耳机本体41可以通过多次统计，得到耳机本体41处于盒外状态时的磁感应强度的最大值和最小值，并将该最大值设置为B4，最小值设置为B3。或者，B3可以为零。The earphone body 41 can count the magnetic induction intensity detected by the magnetic sensor 411 when the earphone body 41 is out of the box, and set the above B4. The earphone body 41 can obtain the maximum and minimum values of the magnetic induction intensity when the earphone body 41 is in the out-of-box state through multiple statistics, and set the maximum value as B4 and the minimum value as B3. Alternatively, B3 can be zero.
可以理解，在实际产品中，处理器412判断检测的磁感应强度时，可以仅使用上述B4和B1。具体的，处理器412响应于磁力计检测的磁感应强度由大于B1变为小于B4，则可以确定耳机本体41出盒；响应于磁力计检测的磁感应强度由小于B4变为大于B1，则可以确定耳机本体41入盒。It can be understood that, in an actual product, when the processor 412 judges the detected magnetic induction intensity, only the above-mentioned B4 and B1 may be used. Specifically, the processor 412 can determine that the earphone body 41 is out of the box in response to the magnetic induction detected by the magnetometer changing from greater than B1 to less than B4; in response to the magnetic induction detected by the magnetometer changing from less than B4 to greater than B1, it can be determined The earphone body 41 is put into the box.
在实现方式(b)中，结合上述第二种情况，对耳机本体41的出盒和入盒检测原理进行说明。In the implementation mode (b), in combination with the second case above, the principle of box-out and box-in detection of the earphone body 41 will be described.
在上述第二种情况中，假设第一强度区间为[Bi，Bii]，第二强度区间为[Biii，Biv]。如图7B所示，第二强度区间[Biii，Biv]的最小磁感应强度Biii大于第二强度区间[Bi，Bii]的最大磁感应强度Bii。上述第一磁场(即处于盒内状态时，耳机本体41周围的磁场)的磁场强度小于第二磁场(即处于盒外状态时，耳机本体41周围的磁场)的磁场强度。In the second case above, it is assumed that the first intensity interval is [Bi, Bii] and the second intensity interval is [Biii, Biv]. As shown in FIG. 7B , the minimum magnetic induction Biii of the second intensity interval [Biii, Biv] is greater than the maximum magnetic induction Bii of the second intensity interval [Bi, Bii]. The magnetic field strength of the first magnetic field (that is, the magnetic field around the earphone body 41 when it is inside the box) is smaller than the magnetic field strength of the second magnetic field (that is, the magnetic field around the earphone body 41 when it is out of the box).
首先，本申请实施例结合图7B对耳机本体41的出盒过程进行说明：First, the embodiment of the present application describes the out-of-box process of the earphone body 41 in conjunction with FIG. 7B:
如图7B所示，在t8时刻-t10时刻这段时间，磁传感器检测到的磁感应强度在第一强度区间[Bi，Bii]内，处理器412可以确定耳机本体41处于盒内状态。假设从图7B所示的t9时刻开始，用户从耳机盒42中取出耳机本体41。由于第二磁场的磁场强度大于第一磁场的磁场强度；因此，用户从耳机盒42中取出耳机本体41的过程中，磁传感器411检测到的磁感应强度会变大。例如，如图7B所示，从t9时刻-t11时刻这段时间内，磁传感器411检测到的磁感应强度逐渐变大。As shown in FIG. 7B , during the period from time t8 to time t10 , the magnetic induction detected by the magnetic sensor is within the first intensity interval [Bi, Bii], and the processor 412 can determine that the earphone body 41 is in the box. Assume that the user takes out the earphone body 41 from the earphone box 42 from time t9 shown in FIG. 7B . Because the magnetic field strength of the second magnetic field is greater than that of the first magnetic field; therefore, when the user takes out the earphone body 41 from the earphone box 42, the magnetic induction intensity detected by the magnetic sensor 411 will become larger. For example, as shown in FIG. 7B , during the period from time t9 to time t11 , the magnetic induction detected by the magnetic sensor 411 gradually increases.
本申请实施例中，在磁传感器411检测的磁感应强度由第一强度区域[Bi，Bii]切换至第三强度区间(如图7B所示的(Bii，Biii))时，处理器412可以确定耳机本体41处于盒内状态。例如，如图7B所示，在t10时刻-t11时刻这段时间，磁传感器411检测到的磁感应强度在(Bii，Biii)内，处理器412可以确定耳机本体41处于盒内状态。In the embodiment of the present application, when the magnetic induction intensity detected by the magnetic sensor 411 is switched from the first intensity range [Bi, Bii] to the third intensity range (as shown in FIG. 7B (Bii, Biii)), the processor 412 may determine that The earphone body 41 is in the box state. For example, as shown in FIG. 7B , during the period from time t10 to time t11, the magnetic induction intensity detected by the magnetic sensor 411 is within (Bii, Biii), and the processor 412 can determine that the earphone body 41 is in the box state.
其中，用户从耳机盒42中取出耳机本体41后，从t11时刻开始(如t11时刻-t12时刻)，磁传感器411检测到的磁感应强度在第二强度区间[Biii，Biv]内，处理器412可以确定耳机本体41处于盒外状态。Wherein, after the user takes out the earphone body 41 from the earphone box 42, from time t11 (such as time t11-time t12), the magnetic induction intensity detected by the magnetic sensor 411 is within the second intensity interval [Biii, Biv], and the processor 412 It can be determined that the earphone body 41 is in an out-of-box state.
如图7B所示，从t9时刻开始截止t11时刻，磁传感器411检测到的磁感应强度从第一强度区域[Bi，Bii]切换至第二强度区间[Biii，Biv]。处理器412响应于磁传感器411检测的磁感应强度从第一强度区域[Bi，Bii]切换至第二强度区间[Biii，Biv]，可以确定耳机本体41出盒。即耳机本体41由盒内状态切换为盒外状态。As shown in FIG. 7B , from time t9 to time t11 , the magnetic induction detected by the magnetic sensor 411 is switched from the first intensity range [Bi, Bii] to the second intensity range [Biii, Biv]. The processor 412 may determine that the earphone body 41 is out of the box in response to the magnetic induction detected by the magnetic sensor 411 switching from the first intensity range [Bi, Bii] to the second intensity range [Biii, Biv]. That is, the earphone body 41 is switched from the state inside the box to the state outside the box.
其次，本申请实施例结合图7B对耳机本体41的入盒过程进行说明：Secondly, the embodiment of the present application describes the box-entry process of the earphone body 41 in conjunction with FIG. 7B:
如图7B所示，在t11时刻-t13时刻这段时间，磁传感器检测到的磁感应强度在第二强度区间[Biii，Biv]内，处理器412可以确定耳机本体41处于盒外状态。假设从图7B所示的t12时刻开始，用户将耳机本体41放入耳机盒42。由于第一磁场的磁场强度小于第二磁场的磁场强度；因此，用户将耳机本体41放入耳机盒42的过程中，磁传感器411检测到的磁感应强度会变小。例如，如图7B所示，从t12时刻-t14时刻这段时间内，磁传感器411检测到的磁感应强度逐渐变小。As shown in FIG. 7B , during the period from time t11 to time t13, the magnetic induction intensity detected by the magnetic sensor is within the second intensity interval [Biii, Biv], and the processor 412 can determine that the earphone body 41 is in the out-of-box state. Assume that the user puts the earphone body 41 into the earphone box 42 from time t12 shown in FIG. 7B . Since the magnetic field intensity of the first magnetic field is smaller than that of the second magnetic field; therefore, when the user puts the earphone body 41 into the earphone box 42 , the magnetic induction intensity detected by the magnetic sensor 411 will decrease. For example, as shown in FIG. 7B , during the period from time t12 to time t14 , the magnetic induction detected by the magnetic sensor 411 gradually decreases.
本申请实施例中，在磁传感器411检测的磁感应强度由第二强度区域[Biii，Biv]切换至第三强度区间(如图7B所示的(Bii，Biii))时，处理器412可以确定耳机本体41处于盒外状态。例如，如图7B所示，在t12时刻-t14时刻这段时间，磁传感器411检测到的磁感应强度在(Bii，Biii)内，处理器412可以确定耳机本体41处于盒外状态。In the embodiment of the present application, when the magnetic induction intensity detected by the magnetic sensor 411 is switched from the second intensity range [Biii, Biv] to the third intensity range (as shown in FIG. 7B (Bii, Biii)), the processor 412 may determine that The earphone body 41 is in an out-of-box state. For example, as shown in FIG. 7B , during the period from time t12 to time t14, the magnetic induction intensity detected by the magnetic sensor 411 is within (Bii, Biii), and the processor 412 can determine that the earphone body 41 is in the out-of-box state.
其中，用户将耳机本体41放入耳机盒42后，从t14时刻开始，磁传感器411检测到的磁感应强度在第一强度区间[Bi，Bii]内，处理器412可以确定耳机本体41处于盒内状态。Wherein, after the user puts the earphone body 41 into the earphone box 42, from time t14, the magnetic induction intensity detected by the magnetic sensor 411 is within the first intensity interval [Bi, Bii], and the processor 412 can determine that the earphone body 41 is in the box state.
如图7B所示，从t12时刻开始到t14时刻，磁传感器411检测到的磁感应强度第二强度区间[Biii，Biv]切换至第一强度区域[Bi，Bii]。处理器412响应于磁传感器411检测的磁感应强度从第二强度区间[Biii，Biv]切换至第一强度区域[Bi，Bii]，可以确定耳机本体41入盒。即耳机本体41由盒外状态切换为盒内状态。As shown in FIG. 7B , from time t12 to time t14 , the magnetic induction detected by the magnetic sensor 411 switches from the second intensity range [Biii, Biv] to the first intensity range [Bi, Bii]. The processor 412 may determine that the headphone body 41 is in the box in response to the magnetic induction detected by the magnetic sensor 411 switching from the second intensity range [Biii, Biv] to the first intensity range [Bi, Bii]. That is, the earphone body 41 is switched from the state outside the box to the state inside the box.
需要说明的是，上述实现方式(b)中，第二强度区间[Biii，Biv]中的Biii和Biv，第一强度区间[Bi，Bii]中的Bii和Bi可以是通过软件设置的。耳机本体41设置Bi、Bii、Biii、Biv的方法可以参考上述实现方式(a)中的描述。不同的是，在实现方式(b)中，Bi可以为零，Biv可以为无穷大。It should be noted that, in the above implementation (b), Biii and Biv in the second intensity interval [Biii, Biv] and Bii and Bi in the first intensity interval [Bi, Bii] may be set by software. For the method of setting Bi, Bii, Biii, and Biv on the earphone body 41, reference may be made to the description in the above implementation (a). The difference is that in implementation (b), Bi can be zero, and Biv can be infinite.
可以理解，在实际产品中，处理器412判断检测的磁感应强度时，可以只使用上述Bii和Biii。具体的，处理器412响应于磁力计检测的磁感应强度由大于Biii变为小于Bii，则可以确定耳机本体41出盒；响应于磁力计检测的磁感应强度由小于B2变为大于Biii，则可以确定耳机本体41入盒。It can be understood that, in an actual product, when the processor 412 judges the detected magnetic induction intensity, only Bii and Biii above may be used. Specifically, the processor 412 can determine that the earphone body 41 is out of the box in response to the magnetic induction detected by the magnetometer changing from greater than Biii to less than Bii; in response to the magnetic induction detected by the magnetometer changing from less than B2 to greater than Biii, it can be determined that The earphone body 41 is put into the box.
需要注意的是，图7A或图7B仅以举例方式给出耳机本体41处于不同状态时，磁传感器411检测的磁感应强度的示意图。在实际产品中，耳机本体41处于对应状态时，磁传感器411检测的磁感应强度的大小和变化曲线包括但不限于图7A或图7B所示的磁感应强度。It should be noted that FIG. 7A or FIG. 7B is only an example showing the magnetic induction intensity detected by the magnetic sensor 411 when the earphone body 41 is in different states. In an actual product, when the earphone body 41 is in a corresponding state, the magnitude and change curve of the magnetic induction detected by the magnetic sensor 411 includes but not limited to the magnetic induction shown in FIG. 7A or 7B .
在另一些实施例中，在上述第一磁场的磁场强度大于第二磁场的磁场强度的情况下，第一强度区间的最小磁感应强度可以等于第二强度区间的最大磁感应强度。以第一强度区间是[Ba，Bb]，第二强度区间是[Bc，Bd]为例，Ba＝Bd。其中，Bb可以为无穷大，Bc可以为零。In some other embodiments, when the magnetic field strength of the first magnetic field is greater than the magnetic field strength of the second magnetic field, the minimum magnetic induction in the first strength interval may be equal to the maximum magnetic induction in the second strength interval. Taking the first intensity interval as [Ba , Bb ] and the second intensity interval as [Bc , Bd ] as an example,Ba = B d. Wherein, Bb can be infinite, and Bc can be zero.
例如，在该实施例中，以磁传感器411是第一类磁传感器(如霍尔传感器)为例。磁传感器411可以用于：检测耳机本体41周围的磁场的磁感应强度；如果检测的磁感应强度大于Ba(或Bd，Ba＝Bd)，向处理器42输出第一信号；如果检测到的磁感应强度小于Ba，向处理器42输出第二信号。For example, in this embodiment, it is taken as an example that the magnetic sensor 411 is a first-type magnetic sensor (such as a Hall sensor). The magnetic sensor 411 can be used to: detect the magnetic induction intensity of the magnetic field around the earphone body 41; if the detected magnetic induction intensity is greater than Ba (or Bd ,Ba = Bd ), output the first signal to the processor 42; if detected If the magnetic induction intensity is less than Ba ,a second signal is output to the processor 42 .
处理器412可以用于：响应于磁传感器411传输的信号由第一信号变为第二信号，确定耳机本体41出盒；响应于磁传感器411传输的信号由第二信号变为第一信号，确定无线耳机入盒。The processor 412 may be configured to: in response to the signal transmitted by the magnetic sensor 411 changing from the first signal to the second signal, determine that the earphone body 41 is out of the box; in response to the signal transmitted by the magnetic sensor 411 changing from the second signal to the first signal, Make sure the wireless earphones are in the box.
需要说明的是，上述第一信号，第二信号，以及处理器412根据第一信号和第二信号的变化确定耳机本体41出盒或入盒的方法，可以参考上述实施例中的相关描述，本申请实施例这里不予赘述。It should be noted that, for the above-mentioned first signal, second signal, and the method for the processor 412 to determine whether the headphone body 41 is out of the box or into the box according to the changes of the first signal and the second signal, you can refer to the relevant description in the above-mentioned embodiment, The embodiment of the present application will not be described in detail here.
又例如，在该实施例中，以磁传感器411是第二类磁传感器(如磁力计)为例。磁传感器411可以用于：检测耳机本体41周围的磁场的磁感应强度。For another example, in this embodiment, it is taken as an example that the magnetic sensor 411 is a second type of magnetic sensor (such as a magnetometer). The magnetic sensor 411 can be used for: detecting the magnetic induction intensity of the magnetic field around the earphone body 41 .
处理器412可以用于：在磁传感器411检测的磁感应强度由大于Ba切换为小于Ba时，确定耳机本体41出盒；在磁传感器411检测的磁感应强度由小于Ba切换为大于Ba时，确定耳机本体41入盒。The processor 412 can be used to: when the magnetic induction intensity detected by the magnetic sensor 411 is switched from greater thanBa to less thanBa , determine that the earphone body 41 is out of the box; when the magnetic induction detected by the magnetic sensor 411 is switched from less thanBa to greater thanBa , it is determined that the earphone body 41 is put into the box.
在上述第一磁场的磁场强度小于第二磁场的磁场强度的情况下，第二强度区间的最小磁感应强度可以等于第一强度区间的最大磁感应强度。以第一强度区间是[BA，BB]，第二强度区间是[BC，BD]为例，BC＝BB。其中，BD可以为无穷大，BA可以为零。In the case that the magnetic field strength of the first magnetic field is smaller than the magnetic field strength of the second magnetic field, the minimum magnetic induction in the second strength interval may be equal to the maximum magnetic induction in the first strength interval. Taking the first intensity interval as [BA , BB ] and the second intensity interval as [BC , BD ] as an example, BC =BB . Among them, BD can be infinite, and BA can be zero.
在这种情况下，耳机本体41对比周围磁场的磁感应强度与BB(或者BC，BC＝BB)，确定耳机本体41出盒或入盒的方法，可以参考上述“第一磁场的磁场强度大于第二磁场的磁场强度”的情况下，耳机本体41对比周围磁场的磁感应强度与Ba，确定耳机本体41出盒或入盒的方法。本申请实施例这里不再赘述。In this case, the earphone body 41 compares the magnetic induction intensity of the surrounding magnetic field withBB (orBC ,BC =BB ), and determines the method for the earphone body 41 to go out of the box or into the box. If the magnetic field strength is greater than the magnetic field strength of the second magnetic field", the earphone body 41 compares the magnetic induction intensity of the surrounding magnetic field with Ba to determine the method for the earphone body 41 to go out of the box or into the box. The embodiment of the present application will not be repeated here.
