Abstract
A MEMS microphone is disclosed. The MEMS microphone includes an encapsulation structure provided with an accommodation space; a MEMS chip for detecting sound signal accommodated in the accommodation space; an ASIC chip received in the accommodation space. The ASIC chip includes a signal processing module connected to MEMS chip for processing the sound signal detected by the MEMS chip and outputting the processed sound signal. The MEMS microphone further includes a temperature detection module for detecting temperature signal and outputting the temperature signal.
