随着移动终端制造技术的快速发展，越来越多的移动设备开始注重语音交互功能，特别是在手机上，基本都会配备有多个麦克风进行不同场景下的语音输入，而麦克风采用内置方式，会在麦克风对应的手机表面上开孔，通过导管进行导通。由于用户使用的环境多样化，如也会有恶劣的环境等，因此常常会遇到麦克风管道孔会被堵住的问题。然而，用户自己本身并不能对麦克风进行检测，只有当用户发现麦克风采集的声音很小时才会想到去售后处，通过售后人员利用检测仪器对麦克风进行检测并清理或者更换，而用户自己不能对麦克风进行检测并做出相应的临时处理，从而影响用户的使用。With the rapid development of mobile terminal manufacturing technology, more and more mobile devices begin to focus on the voice interaction function, especially on mobile phones, which are basically equipped with multiple microphones for voice input in different scenarios, and the microphones are built-in. A hole will be opened on the surface of the mobile phone corresponding to the microphone, and the conduction will be conducted through the conduit. Due to the diversity of environments used by users, such as harsh environments, etc., the problem that the microphone pipe hole will be blocked is often encountered. However, the user himself cannot detect the microphone. Only when the user finds that the sound collected by the microphone is very small will he think of going to the after-sales office. The after-sales personnel use the detection instrument to detect and clean or replace the microphone. Detect and make corresponding temporary processing, thereby affecting the use of users.

下面参考附图描述本发明实施例的移动终端中麦克风的检测方法、装置以及移动终端。The method and device for detecting a microphone in a mobile terminal and the mobile terminal according to the embodiments of the present invention will be described below with reference to the accompanying drawings.
图1是根据本发明一个实施例的移动终端中麦克风的检测方法的流程图。需要说明的是，在本发明的实施例中，该移动终端可以是手机、平板电脑、个人数字助理等具有各种操作的硬件设备。可以理解，该移动终端可以有至少一个麦克风。Fig. 1 is a flowchart of a method for detecting a microphone in a mobile terminal according to an embodiment of the present invention. It should be noted that, in the embodiment of the present invention, the mobile terminal may be a hardware device with various operations, such as a mobile phone, a tablet computer, and a personal digital assistant. It can be understood that the mobile terminal may have at least one microphone.
如图1所示，该移动终端中麦克风的检测方法可以包括：As shown in Figure 1, the detection method of microphone in this mobile terminal can comprise:
S101，控制移动终端中的音频输出设备播放预设大小的超声波检测信号。S101. Control an audio output device in a mobile terminal to play an ultrasonic detection signal of a preset size.
其中，在本发明的一个实施例中，该音频输出设备可包括扬声器或受话器。例如，可控制移动终端中的扬声器或受话器播放超声波检测信号，该检测信号的声音大小可以根据实际需要进行设定。可以理解，上述超声波检测信号可以是预先存储于移动终端中，当对移动终端的麦克风进行检测时，可从移动终端中获取预先存储的超声波检测信号，并控制扬声器或受话器播放该超声波检测信号，该超声波检测信号的播放声音大小可以是上述的预设大小。Wherein, in an embodiment of the present invention, the audio output device may include a speaker or a receiver. For example, a loudspeaker or receiver in the mobile terminal can be controlled to play an ultrasonic detection signal, and the sound level of the detection signal can be set according to actual needs. It can be understood that the above-mentioned ultrasonic detection signal may be pre-stored in the mobile terminal. When detecting the microphone of the mobile terminal, the pre-stored ultrasonic detection signal may be obtained from the mobile terminal, and the speaker or receiver may be controlled to play the ultrasonic detection signal. The volume of the playing sound of the ultrasonic detection signal may be the above-mentioned preset volume.
在本发明的另一个实施例中，该音频输出设备可包括扬声器和受话器。其中，在本发明的实施例中，可控制扬声器和受话器同时播放预设大小的超声波检测信号。也就是说，在对移动终端的麦克风进行检测时，可控制扬声器和受话器同时播放相同大小的超声波检测信号。In another embodiment of the present invention, the audio output device may include a speaker and a receiver. Wherein, in the embodiment of the present invention, the loudspeaker and the receiver can be controlled to simultaneously play an ultrasonic detection signal of a preset size. That is to say, when detecting the microphone of the mobile terminal, the speaker and the receiver can be controlled to simultaneously play ultrasonic detection signals of the same size.
举例而言，假设本发明实施例的移动终端中麦克风的检测方法可应用于移动终端，该移动终端可为用户提供检测麦克风是否发生异常的应用程序，当用户启动或运行该应用程序时，可控制移动终端中的扬声器和/或受话器播放预设大小的超声波检测信号。For example, assuming that the method for detecting a microphone in a mobile terminal according to an embodiment of the present invention can be applied to a mobile terminal, the mobile terminal can provide the user with an application program for detecting whether the microphone is abnormal, and when the user starts or runs the application program, it can Controlling the speaker and/or the receiver in the mobile terminal to play the ultrasonic detection signal with a preset size.
S102，获取麦克风所采集的声音信号，并将声音信号转换为对应的数字信号。S102. Acquire the sound signal collected by the microphone, and convert the sound signal into a corresponding digital signal.
具体地，在控制移动终端中的音频输出设备播放超声波检测信号时，可开启该移动终端的麦克风，并通过麦克风收集音频输出设备播放的超声波检测信号。当麦克风声音收集结束时，可获取该麦克风所收集到的声音信号，并通过模数转换器将该声音信号转换为对应的数字信号。可以理解，该数字信号为一个数值。Specifically, when controlling the audio output device in the mobile terminal to play the ultrasonic detection signal, the microphone of the mobile terminal can be turned on, and the ultrasonic detection signal played by the audio output device can be collected through the microphone. When the sound collection by the microphone is finished, the sound signal collected by the microphone can be obtained, and the sound signal can be converted into a corresponding digital signal by an analog-to-digital converter. It can be understood that the digital signal is a value.
作为一种示例，当音频输出设备包括扬声器和受话器时，麦克风收集声音时，可将收集到的扬声器播放的超声波检测信号和受话器播放的超声波检测信号合成一个信号，该合成信号即为上述声音信号。As an example, when the audio output device includes a speaker and a receiver, when the microphone collects sound, the collected ultrasonic detection signal played by the speaker and the ultrasonic detection signal played by the receiver can be synthesized into one signal, and the composite signal is the above-mentioned sound signal .
需要说明的是，上述麦克风可以是具有使用权限的麦克风，具有使用权限可理解为当前常被移动终端所使用、并起主导作用，如语音输入时使用该麦克风收集声音；上述麦克风还可以是移动终端中的所有麦克风，可以理解，当移动终端中有多个麦克风时，可对移动终端中的所有麦克风进行异常检测。It should be noted that the above-mentioned microphone may be a microphone with permission to use, which can be understood as being often used by mobile terminals and playing a leading role, such as using the microphone to collect sound during voice input; the above-mentioned microphone can also be a mobile For all the microphones in the terminal, it can be understood that when there are multiple microphones in the mobile terminal, anomaly detection can be performed on all the microphones in the mobile terminal.
S103，确定与麦克风对应的基准阈值，并根据数字信号和基准阈值检测麦克风是否发生异常。S103. Determine a reference threshold corresponding to the microphone, and detect whether the microphone is abnormal according to the digital signal and the reference threshold.
需要说明的是，在本发明的一个实施例中，基准阈值可预先通过以下步骤获得：在隔音屏蔽环境下，控制移动终端中的音频输出设备播放预设大小的超声波检测信号；获取移动终端中各个麦克风所收集的声音信号；将各个麦克风所收集的声音信号转换为对应的数字信号，并将各个数字信号的大小作为各个麦克风的基准阈值。It should be noted that, in one embodiment of the present invention, the reference threshold can be obtained in advance through the following steps: in a soundproof and shielding environment, control the audio output device in the mobile terminal to play an ultrasonic detection signal of a preset size; obtain the ultrasonic detection signal in the mobile terminal The sound signal collected by each microphone; the sound signal collected by each microphone is converted into a corresponding digital signal, and the magnitude of each digital signal is used as a reference threshold for each microphone.
例如，在移动终端出厂前，首先移动终端中的扬声器、受话器和麦克风需要通过产线自动化测试标准，并满足产线上的主观功能测试，然后在隔音屏蔽环境下对移动终端中的各个麦克风进行校准，如控制扬声器和受话器输出相同大小的特定超声波检测信号，各个麦克风拾取到两个位置音源的合成信号，并通过模数转换器将各个麦克风采集到的声音信号转换为对应的数字信号。作为一种示例，可进行多次测量，并针对各个麦克风，将该多次测量得到的数字信号进行求平均，并将得到的平均值作为该麦克风发生堵孔等异常情况的参考值，并将该平均值作为该麦克风的基准阈值。For example, before the mobile terminal leaves the factory, the speakers, receivers and microphones in the mobile terminal first need to pass the production line automation test standard and meet the subjective function test on the production line, and then test each microphone in the mobile terminal in a sound-proof shielding environment. Calibration, such as controlling the speaker and the receiver to output a specific ultrasonic detection signal of the same size, each microphone picks up the composite signal of two sound sources, and converts the sound signal collected by each microphone into a corresponding digital signal through an analog-to-digital converter. As an example, multiple measurements can be carried out, and for each microphone, the digital signals obtained by the multiple measurements are averaged, and the obtained average value is used as a reference value for an abnormal situation such as a hole blocking of the microphone, and the This average value serves as the baseline threshold for the microphone.
在本发明的实施例中，确定与麦克风对应的基准阈值的具体实现过程可如下：获取麦克风的标识，并根据标识从各个麦克风的基准阈值中确定与麦克风对应的基准阈值。In the embodiment of the present invention, the specific implementation process of determining the reference threshold corresponding to the microphone may be as follows: obtain the identification of the microphone, and determine the reference threshold corresponding to the microphone from the reference thresholds of each microphone according to the identification.
具体而言，在本发明的一个实施例中，在确定麦克风对应的基准阈值之后，可判断上述数字信号是否满足基准阈值，如果该数字信号满足基准阈值，则可判定该麦克风正常，如果数字信号不满足基准阈值，则判定该麦克风发生异常，如发生堵孔、麦克风器件损坏等情况。Specifically, in one embodiment of the present invention, after determining the reference threshold corresponding to the microphone, it can be judged whether the digital signal satisfies the reference threshold. If the digital signal meets the reference threshold, it can be determined that the microphone is normal. If the digital signal If the reference threshold is not met, it is determined that the microphone is abnormal, such as hole blocking, microphone device damage, and the like.
需要说明的是，在本发明的实施例中，上述基准阈值可以是单个数值，还可以是由多个数值组成的范围值。当该基准阈值为单个数值时，可将上述得到的数字信号与该基准阈值进行大小比对，如果数字信号的大小大于或等于该基准阈值，则可判定对应的麦克风正常，如果数字信号的大小小于该基准阈值，则可判定该麦克风发生异常；当该基准阈值为范围值时，可判断上述数字信号是否在该基准阈值范围之内，如果该数字信号的大小在该基准阈值范围之内，则可判断该麦克风正常，如果该数字信号的大小不在该基准阈值范围之内，则可判断该麦克风发生异常。It should be noted that, in the embodiment of the present invention, the aforementioned reference threshold may be a single value, or may be a range value composed of multiple values. When the reference threshold is a single value, the digital signal obtained above can be compared with the reference threshold. If the size of the digital signal is greater than or equal to the reference threshold, it can be determined that the corresponding microphone is normal. If the size of the digital signal If it is less than the reference threshold, it can be determined that the microphone is abnormal; when the reference threshold is a range value, it can be judged whether the above-mentioned digital signal is within the reference threshold range, if the magnitude of the digital signal is within the reference threshold range, Then it can be judged that the microphone is normal, and if the magnitude of the digital signal is not within the reference threshold range, it can be judged that the microphone is abnormal.
还需要说明的是，为了提高准确度，还可对移动终端中的麦克风进行多次检测，如果该麦克风多次测试仍然不满足对应的基准阈值，则可判定该麦克风发生异常。It should also be noted that, in order to improve the accuracy, the microphone in the mobile terminal may be detected multiple times, and if the microphone still fails to meet the corresponding reference threshold after multiple tests, it may be determined that the microphone is abnormal.

If only the digital signal of the current microphone does not meet the reference threshold, it can be determined that the current microphone When the microphone is abnormal, select a normal microphone from other microphones, and then change the permission of the other normal microphone to use permission, such as using the other normal microphone to collect sound during voice input, and switch the abnormal microphone to Other normal microphones, and adjust the sensitivity of the other microphones and the corresponding audio parameters to ensure the sound input effect of the other microphones. As a result, by intelligently switching microphones at other locations when an abnormality occurs in the detection of the microphone component, the problem of temporarily dealing with the plugging of the microphone is solved, and the temporary use needs of the user are met.
