Background
In the prior art, detection of a microphone function in a mobile terminal (taking a mobile phone as an example) in a complete machine by a production line is generally simple loop detection, that is, a signal is sent from a microphone end and then comes out from a receiver or a loudspeaker, and as long as a sound is heard, the microphone function is judged to be normal. For a mobile phone with 2 microphones, 1 microphone is tested, and the other microphone is tested again, namely, the test is carried out for 2 times, and the efficiency is not high.
Meanwhile, due to structural limitation, the microphone at the top is often close to the receiver, part of sound emitted by the receiver leaks to the vicinity of the microphone, and is sent to the receiver end again after being picked up by the microphone, so that positive feedback is formed, and howling is caused; because the overall level of workers is not high, the howling is easy to make misjudgment, and even whether the function is normal or not cannot be judged, and the performance of the microphone device is influenced when the howling is severe. Some manufacturers change designs to allow signals sent by the microphones to come out of the loudspeakers, and although the loudspeakers are relatively far away from the top microphone, sound is still leaked to the top microphone due to the fact that the volume of the loudspeakers is usually large, howling cannot be avoided, and the probability can be reduced to a certain extent.
