MICROPHONE SYSTEM COMPRISING A RESET CIRCUIT FOR MEMS CAPACITIVE MICROPHONES AND METHOD THEREFOR

摘要

A kind of initiation homing sequence MEMS capacitance microphones. This method includes that monitoring exports the silent condition of microphone detection for loudspeaker output instruction fault state. This method further include: activation timing circuit. Timing circuit is configured as instruction in certain time period since timing circuit starts to pass. Expire instruction by timing circuit in the time cycle, microphone resetting sequence is initiated.
