Embodiment Construction
[0038] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0039] At present, in order to improve call quality and manufacture higher-quality mobile phones, mobile phone manufacturers usually adopt a dual-mic design for the microphone in the mobile phone. Generally speaking, the user uses the microphone at the bottom of the phone when making a call, and uses the microphone at the top when the user turns on the speakerphone or makes a video call. Therefore, before the mobile phone leaves the fac...

The invention provides a double-microphone test method and device. The method comprises the following steps: obtaining a recording file which is obtained through the alternate storage of recording information at the same moment according to first sound channel data and second sound channel data, and the first sound channel data is recorded by a first microphone; wherein the second sound channel data is recorded by a second microphone; for any moment, extracting first sound channel data at the moment and second sound channel data at the moment from the sound recording file; comparing the firstsound channel data at the moment with the second sound channel data at the moment to obtain a recording comparison result at the moment; and determining whether the first microphone and the second microphone are in a normal working state or not according to the recording comparison results of the multiple moments. According to the scheme, the first sound channel data and the second sound channel data of the double microphones at multiple moments are compared, and whether the double microphones are in the normal working state or not can be determined according to the comparison result, so thata mobile phone with abnormal microphones can be detected by a production line in the microphone testing process.
Description
technical field [0001] The invention relates to the field of data processing, in particular to a double microphone testing method and device. Background technique [0002] At present, manufacturers of mobile phones need to conduct various tests on their mobile phones, one of which is the performance test of the left and right dual microphones built into the mobile phone. [0003] For the test of the left and right dual microphones of mobile phones, the industry mainly adopts a separate test method. Here we take the test of the left microphone as an example: first, let the left microphone enter the recording state and start recording; then, the software calculates the data volume of the left channel through an algorithm, when the volume value of the left channel data exceeds a certain threshold (such as can be 60DB), then stop the recording; finally, play the recording file, and manually check whether the recording content of the left microphone is correct. When the algorit...
