Abstract
A device and method controlling a speaker to emit a sound to protect a microphone is provided. An example device: determines, using a motion detector, when a drop is occurring. The example device, in response to determining that a drop is occurring: controls a speaker of the example device to emit a sound according to one or more predetermined drop parameters, the sound to apply an acoustic pressure at a membrane of the MEMS microphone of the example device to reduce a deflection thereof that results due to one or more of the drop and an impact which ends the drop.
