Description
Technical field
The present invention relates to technical field of mobile terminals, and in particular to a kind of detection method for preventing microphone whistle, movement
Terminal and storage medium.
Background technology
Producing line is to mobile terminal in the prior art（By taking mobile phone as an example）The detection of microphone function in complete machine, generally all it is letter
Single loop detection, i.e., send a signal from microphone end, allow signal to be come out again from receiver or loudspeaker, as long as hearing sound
Sound, that is, judge that microphone function is normal.For there is the mobile phone of 2 microphones, then tested 1 microphone, re-test another,
Test 2 times, it is inefficient.
Simultaneously because structure limits, the microphone at top is often close from receiver, and the sound that receiver issues has part again
Leak near microphone, after being picked up by microphone, be again sent to receiver end, be consequently formed a positive feedback, cause to utter long and high-pitched sounds；
Because worker's integral level is not high, utter long and high-pitched sounds easily allow its produce erroneous judgement, or even can not arbitration functions it is whether normal, severity of uttering long and high-pitched sounds
When, Mike's device performance can also be had an impact.Also the signal for having the change design of some manufacturers to allow microphone to send goes out from loudspeaker
Come, although loudspeaker are from top microphone relatively far away from, because horn volume is generally larger, still has sound and be leaked to top wheat
Gram wind, is not avoided that generation of uttering long and high-pitched sounds equally, can only reduce probability to a certain extent.
Therefore, prior art has yet to be improved and developed.
The content of the invention
The technical problem to be solved in the present invention is, for the drawbacks described above of prior art, there is provided one kind prevents microphone
