本实用新型属于音频输出设备技术领域，具体地说，是涉及一种无线耳机。The utility model belongs to the technical field of audio output equipment, in particular to a wireless earphone.
背景技术Background technique
无线耳机是一种以无线电波的形式接收音频信号源（主机）发射的音频数据，并处理成模拟音频信号，推动扬声器发声的音频播放设备。无线耳机相比于传统的有线耳机，其良好的便携性在日常生活中得到了广泛应用。例如，当人们正在开车、运动不方便接听电话时，可以使用无线耳机接听电话，通过解放人们的双手，使得驾车更加安全，运动更加自如。A wireless headset is an audio playback device that receives audio data emitted by an audio signal source (host) in the form of radio waves, processes it into an analog audio signal, and pushes the speaker to sound. Compared with traditional wired earphones, wireless earphones are widely used in daily life due to their good portability. For example, when people are driving and it is inconvenient to answer the phone when they are exercising, they can use wireless earphones to answer the phone. By freeing people's hands, driving is safer and movement is more free.
无线耳机通过内置电池为其供电，从佩戴方式上可分为头戴式无线耳机和入耳式无线耳机两种类型。对于入耳式的无线耳机，要求产品自身的体积应尽量做到非常小，因此目前市面上几乎所有的入耳式无线耳机都采用可充电的纽扣电池进行供电。由于纽扣电池的体积小，电量存储能力有限，为延长耳机的续航时间，当用户取下耳机时，最好使耳机能够自动进入暂停模式，以降低耳机功耗，节约电能。Wireless earphones are powered by a built-in battery, and can be divided into two types: head-mounted wireless earphones and in-ear wireless earphones. For in-ear wireless headphones, the volume of the product itself should be as small as possible, so almost all in-ear wireless headphones on the market are powered by rechargeable button batteries. Due to the small size of the button battery and limited power storage capacity, in order to prolong the battery life of the headset, when the user removes the headset, it is best to enable the headset to automatically enter the pause mode to reduce the power consumption of the headset and save power.
自从苹果公司推出具有佩戴检测功能的AirPods TWS耳机之后，各大耳机制造公司也都在研发类似的耳机产品。这种类型的耳机能够自动识别出用户佩戴和取下耳机的动作，继而根据用户的动作控制耳机自动播放与暂停，为用户的日常使用提供了极大地便利。为了在耳机上实现佩戴检测功能，目前最常采用的方法是在耳机中增设一个接近感应传感器P-Sensor，利用接近感应传感器感知耳机与人耳的接近状态，继而生成检测结果，控制耳机的工作状态。这种接近感应传感器是一个独立的部件，需要在耳机中为其单独分配一个容纳空间，这对于体积小巧的入耳式无线耳机而言，在空间分配上很难实现，而且在结构设计上，为满足接近感应传感器的工作要求，还需要在耳机外壳上开窗，不仅增加了耳机结构的设计难度，同时也导致耳机成本明显升高。Since Apple introduced the AirPods TWS earphones with wearing detection function, major earphone manufacturers are also developing similar earphone products. This type of earphone can automatically recognize the user's actions of putting on and taking off the earphone, and then control the earphone to automatically play and pause according to the user's action, which provides great convenience for the user's daily use. In order to realize the wearing detection function on the earphone, the most commonly used method is to add a proximity sensor P-Sensor to the earphone, and use the proximity sensor to sense the proximity state of the earphone and the human ear, and then generate the detection result to control the work of the earphone. state. This proximity sensor is an independent component, which needs to be allocated a separate accommodation space in the earphone, which is difficult to realize in terms of space allocation for small-sized in-ear wireless earphones, and in terms of structural design, it is To meet the working requirements of the proximity sensor, it is also necessary to open a window on the earphone shell, which not only increases the difficulty of designing the earphone structure, but also leads to a significant increase in the cost of the earphone.

具体实施方式Detailed ways
下面结合附图对本实用新型的具体实施方式作进一步详细地说明。The specific embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.
本实用新型为了在耳机上实现佩戴检测功能，基于静电感应原理，采用在耳机的内置电池上贴附多段金属层的方式，生成多个触摸感应区，利用金属层在接近人体时能够在其中产生感应电荷的特性，配合触控芯片对每一段金属层感应生成的电荷数量进行检测，通过数量对比，实现对用户佩戴/取下耳机动作的准确识别。In order to realize the wearing detection function on the earphone, the utility model adopts the method of attaching multiple metal layers on the built-in battery of the earphone based on the principle of electrostatic induction to generate a plurality of touch sensing areas, and the metal layer can be used to generate induction in it when it is close to the human body.

下面通过两个具体的实施例，对本实用新型的耳机结构设计及其工作原理进行具体阐述。The structural design and working principle of the earphone of the present invention will be described in detail below through two specific embodiments.
实施例一，如图1所示，本实施例的耳机为入耳式的无线耳机，包括外壳1和内置于外壳1中的电池2。所述电池2优选采用可充电电池，以方便用户的日常使用。考虑到入耳式耳机的尺寸普遍较小，为了便于将电池2安装在耳机小巧的外壳1中，所述电池2最好选择可充电的纽扣电池。目前最为常见的可充电纽扣电池2大多呈圆柱体结构，结合图2所示，包括顶面3、底面4和四周侧面5。考虑到耳机对续航能力的要求，耳机中所选用的可充电纽扣电池2的容量较大，电池一般较厚，其侧面5宽度D通常可达5mm-6mm，适于金属层6在其上布设。Embodiment 1, as shown in FIG. 1 , the earphone in this embodiment is an in-ear wireless earphone, which includes a casing 1 and a battery 2 built in the casing 1 . The battery 2 is preferably a rechargeable battery to facilitate the daily use of the user. Considering that the size of the in-ear earphone is generally small, in order to facilitate the installation of the battery 2 in the compact casing 1 of the earphone, the battery 2 is preferably a rechargeable button battery. At present, the most common rechargeable button batteries 2 are mostly cylindrical structures, and as shown in FIG. Considering the requirements of the earphones on the endurance, the rechargeable button battery 2 selected in the earphones has a large capacity, and the battery is generally thick. .
本实施例的金属层6优选采用铜箔，包括多段，贴附在纽扣电池2的侧面5，且环绕纽扣电池2一周，呈等间距圆周排布，如图2所示，继而在纽扣电池2的侧面5形成多个触摸感应区，用于感应人体的触摸方式。为了提高耳机佩戴检测的准确性，优选在电池2的侧面5均匀贴附至少三段铜箔6，每一段铜箔6的面积最好相等，铜箔6的宽度W可与电池侧面5的宽度D相等或者接近，例如可以设计铜箔6的宽度W略小于电池2的侧面宽度D，如小于电池侧面5的宽度1mm左右，在保证铜箔6具有稳固贴附力的同时，通过尽量增大铜箔6的面积，可确保耳机在佩戴后，一圈铜箔6均能与用户的耳廓相接近，继而在每一段铜箔6中感应出电荷数量相等或相近的电荷。The metal layer 6 in this embodiment is preferably made of copper foil, which includes multiple sections, is attached to the side 5 of the button battery 2 , and surrounds the button battery 2 , and is arranged in an equidistant circle, as shown in FIG. 2 , and then on the button battery 2 The side 5 of the device forms a plurality of touch sensing areas, which are used to sense the touch mode of the human body. In order to improve the accuracy of the earphone wearing detection, preferably at least three sections of copper foil 6 are evenly attached to the side 5 of the battery 2, the area of each section of the copper foil 6 is preferably equal, and the width W of the copper foil 6 can be the same as the width of the side 5 of the battery. D is equal to or close to, for example, the width W of the copper foil 6 can be designed to be slightly smaller than the side width D of the battery 2, for example, smaller than the width of the side 5 of the battery by about 1 mm. The area of the copper foil 6 can ensure that after the earphone is worn, a circle of the copper foil 6 can be close to the user's auricle, and then the same or similar charges are induced in each section of the copper foil 6 .
在将贴附有铜箔6的纽扣电池2安装在耳机外壳1中时，优选设计耳机外壳1在纽扣电池2的侧面5均匀包覆，如图1所示，且耳机外壳1包覆电池侧面5的部分在耳机佩戴到位后，均与用户的耳廓接近或贴合。可以将耳机外壳1包覆电池侧面5的部分直接与各段铜箔6相贴合，也可以与各段铜箔6间隔开等距离的间隙，以进一步确保耳机在佩戴后，各段铜箔6中能够感应出数量相当的感应电荷。When the button battery 2 attached with the copper foil 6 is installed in the earphone case 1, it is preferable to design the earphone case 1 to cover the side 5 of the button battery 2 evenly, as shown in FIG. 1, and the earphone case 1 covers the side of the battery The part of 5 is close to or fit the user's auricle after the earphone is put in place. The part of the earphone shell 1 covering the side 5 of the battery can be directly attached to each section of copper foil 6, or it can be spaced equidistant from each section of copper foil 6 to further ensure that after the earphone is worn, each section of copper foil A considerable amount of induced charges can be induced in 6.
入耳式耳机的外壳1一般分成前段11和后段12，如图1所示，前段11中通常内置有电声转换部件，在耳机佩戴时插入到用户的耳孔中，将声音传入用户的耳道。外壳1的后段12通常内置电路板和电池2，利用外壳1的后段12将电路板和电池2完全包覆，以使耳机电路与外界隔离。The shell 1 of the in-ear earphone is generally divided into a front section 11 and a rear section 12. As shown in Figure 1, the front section 11 is usually built with an electro-acoustic conversion component, which is inserted into the user's ear hole when the earphone is worn, and the sound is transmitted to the user's ear. road. The rear section 12 of the casing 1 usually has a built-in circuit board and a battery 2, and the circuit board and the battery 2 are completely covered by the rear section 12 of the casing 1 to isolate the headphone circuit from the outside world.
本实施例在电路板上布设有触控芯片Touch IC，如图4所示，连接所述铜箔6，用于检测每一段铜箔6产生的感应电荷，并根据每一段铜箔6产生的感应电荷的数量生成耳机佩戴状态检测结果。在本实施例中，所述触控芯片Touch IC具有多路电荷采集通道，所述电荷采集通道的数量应不少于所述铜箔6的段数。在每一段铜箔6上分别连接一根导线7，不同的铜箔6通过导线7与不同的电荷采集通道相连接。以三段铜箔6为例，选择触控芯片Touch IC中的三路电荷采集通道channel_l、channel_2、channel_3分别通过导线7与三段铜箔6一一对应连接，分别采集三段铜箔6中生成的感应电荷。In this embodiment, a touch chip Touch IC is arranged on the circuit board. As shown in FIG. 4 , the copper foil 6 is connected to detect the induced charge generated by each section of the copper foil The number of induced charges generates the detection result of the earphone wearing state. In this embodiment, the touch chip Touch IC has multiple charge collection channels, and the number of the charge collection channels should not be less than the number of segments of the copper foil 6 . A wire 7 is respectively connected to each section of copper foil 6 , and different copper foils 6 are connected to different charge collection channels through the wire 7 . Taking the three-segment copper foil 6 as an example, select the three-way charge collection channels channel_1, channel_2, and channel_3 in the touch chip Touch IC to connect with the three-segment copper foil 6 one-to-one through the wire 7 respectively, and collect the three-segment copper foil 6 respectively. generated induced charge.
当用户将耳机佩戴在耳朵上时，耳机的整个外壳1都比较靠近人体的皮肤，其中，外壳1包覆所述电池2的侧面5的部分完全与用户的耳廓贴合或接近，从而会在每一段铜箔6中分别感应出几乎数量相等的感应电荷。利用触控芯片Touch IC采集每一段铜箔6上感应生成的电荷数量，若电荷数量相等或接近，例如各段铜箔6上生成的感应电荷数量的差值在设定的阈值（所述阈值可以根据实验确定）范围内，则判定耳机处于佩戴状态，生成佩戴检测结果发送至耳机线路板上既有的处理器，以控制耳机中的各功能模块进入工作状态。若触控芯片Touch IC检测到每一段铜箔6上感应生成的电荷数量相差较大，例如各段铜箔6上生成的感应电荷数量的差值超过设定阈值，则判定耳机处于取下状态，生成佩戴检测结果发送至所述处理器，以控制耳机中的各功能模块进入暂停状态，以降低耳机功耗。由此，便在耳机中实现了佩戴检测功能。When the user wears the earphone on the ear, the entire casing 1 of the earphone is relatively close to the skin of the human body, wherein the part of the side 5 of the casing 1 covering the battery 2 is completely fitted or close to the user's auricle, so that the Almost the same amount of induced charges are induced in each section of copper foil 6 . Use the touch chip Touch IC to collect the amount of charges induced on each section of copper foil 6. If the amount of charges is equal or close, for example, the difference between the amounts of induced charges generated on each section of copper foil 6 is within a set threshold (the threshold It can be determined according to experiments), then it is determined that the earphone is in the wearing state, and the wearing detection result is generated and sent to the existing processor on the earphone circuit board to control each functional module in the earphone to enter the working state. If the touch chip Touch IC detects that the amount of charges induced on each section of copper foil 6 differs greatly, for example, the difference in the amount of induced charges generated on each section of copper foil 6 exceeds the set threshold, it is determined that the earphone is in the removed state , and the wearing detection result is generated and sent to the processor, so as to control each functional module in the headset to enter a pause state, so as to reduce the power consumption of the headset. Thus, the wearing detection function is implemented in the earphone.
实施例二，如图3所示，本实施例与实施例一的区别在于金属层的选择上。本实施例的金属层采用在FPC柔性板（又称柔性电路板）上刻蚀焊盘的方式形成。具体来讲，可以在电池2的侧面5包覆一圈FPC柔性板8，在FPC柔性板8上刻蚀多个金属焊盘9，所述多个金属焊盘9的面积相等，呈等间距圆周排布，且焊盘9的数量最好大于等于3个，以提高佩戴检测结果的准确性。Embodiment 2, as shown in FIG. 3 , the difference between this embodiment and Embodiment 1 lies in the selection of the metal layer. The metal layer in this embodiment is formed by etching pads on an FPC flexible board (also known as a flexible circuit board). Specifically, a circle of FPC flexible board 8 can be covered on the side 5 of the battery 2 , and a plurality of metal pads 9 can be etched on the FPC flexible board 8 , and the metal pads 9 have the same area and are equally spaced. Circumferential arrangement, and the number of pads 9 is preferably greater than or equal to 3, so as to improve the accuracy of wearing detection results.
在每一个焊盘9上分别焊接一根导线10，通过导线10分别与触控芯片Touch IC上的不同电荷采集通道一一对应连接。当用户将本实施例的耳机佩戴在耳朵上时，外壳1中包覆所述FPC柔性板8的部分均与耳廓贴合或接近，由此利用人体所带静电，可以在每一个焊盘9上感应生成数量相等或相近的感应电荷，触控芯片Touch IC通过采集每一个焊盘9上感应生成的电荷数量，并进行比较，若电荷数量接近，即可认为耳机处于佩戴状态；若电荷数量相差较远，则可认为耳机处于非佩戴状态。根据识别出的佩戴状态，触控芯片Touch IC生成检测结果发生至耳机中的处理器，所述触控芯片Touch IC和处理器也可以集成在一颗芯片中，继而根据检测结果即可控制耳机在佩戴时自动播放声音，而在取下时自动暂停，从而达到简化用户操作、降低耳机功耗的技术效果。A wire 10 is soldered on each pad 9 respectively, and the wires 10 are respectively connected to different charge collection channels on the touch chip Touch IC in a one-to-one correspondence. When the user wears the earphone of this embodiment on the ear, the part of the casing 1 covering the FPC flexible board 8 is in contact with or close to the auricle. The number of induced charges generated by induction on 9 is equal or similar. The touch chip Touch IC collects the number of charges induced on each pad 9 and compares them. If the number of charges is close, it can be considered that the headset is in the wearing state; If the number is far away, it can be considered that the headset is in a non-wearing state. According to the identified wearing state, the touch chip Touch IC generates the detection result and sends it to the processor in the earphone. The touch chip Touch IC and the processor can also be integrated in one chip, and then the earphone can be controlled according to the detection result. The sound is automatically played when it is worn, and automatically paused when it is removed, so as to achieve the technical effect of simplifying user operation and reducing the power consumption of the headset.
本实施例的耳机的其它结构设计可采用与实施例一相同的设计方式。Other structural designs of the earphones in this embodiment can be designed in the same manner as in the first embodiment.
本实用新型采用在耳机内置电池的外周贴附多段金属层的方式，形成多个触摸感应区，通过对各个触摸感应区的感应电荷数量进行监控，即可有效地识别出用户佩戴和取下耳机的动作，实现耳机对其佩戴状态的准确检测。具体来讲，若耳机正常佩戴在耳朵上，各段金属层均与耳廓接近，产生的感应电荷数量接近；若耳机拿在用户手中，无论是放在手掌上还是两指夹捏，只会有其中的一段或几段金属层接近人体，产生感应电荷，因此在对各个触摸感应区进行检测时，各触摸感应区生成的感应电荷数量不均等；若耳机放在桌子、椅子等远离人体的物体上，则各个触摸感应区无感应电荷生成。由此，通过对比各个触摸感应区感应生成的电荷数量，即可准确地判断出耳机的佩戴状态，且误判率较低。The utility model adopts the method of attaching multiple metal layers on the periphery of the built-in battery of the earphone to form a plurality of touch sensing areas, and by monitoring the number of induced charges in each touch sensing area, it can be effectively recognized that the user wears and takes off the earphone action to achieve accurate detection of the wearing state of the headset. Specifically, if the earphone is normally worn on the ear, each segment of the metal layer is close to the auricle, and the amount of induced charges generated is similar; if the earphone is held in the user's hand, whether it is placed on the palm of the hand or pinched with two fingers, only the One or several sections of the metal layer are close to the human body and generate induced charges. Therefore, when detecting each touch-sensitive area, the amount of induced charges generated by each touch-sensitive area is not equal; if the headset is placed on a table, chair, etc. On the object, no induced charge is generated in each touch-sensitive area. Therefore, the wearing state of the earphone can be accurately determined by comparing the amount of charges induced and generated by each touch sensing area, and the misjudgment rate is low.
此外，本实用新型的耳机结构设计简单，尤其适合应用在体积小巧的入耳式无线耳机中。在入耳式无线耳机中，电池基本上是其最大的部件，电池的大小决定了耳机的尺寸，必须单独设置容纳空间。该容纳空间正好可以作为多段金属层的安装空间，无需对耳机的内部空间结构重新进行分配，因此可以大大降低耳机结构的设计难度，节约设计成本。In addition, the earphone of the utility model has a simple structure design, and is especially suitable for application in a small-sized in-ear wireless earphone. In the in-ear wireless headset, the battery is basically its largest component. The size of the battery determines the size of the headset, and the accommodation space must be set separately. The accommodating space can just be used as the installation space of the multi-segment metal layers, and there is no need to redistribute the internal space structure of the earphone, so the design difficulty of the earphone structure can be greatly reduced, and the design cost can be saved.
当然，本实用新型提出的耳机结构设计在除了入耳式无线耳机以外的其他类型的耳机中同样适用。Of course, the earphone structure design proposed by the present invention is also applicable to other types of earphones except in-ear wireless earphones.
