Abstract
A signal processing method and device of a MEMS microphone and a MEMS microphone are disclosed. The method comprises: acquiring a first electrical signal obtained by converting a received optical signal by an optical sensor disposed near a sound hole of the MEMS microphone; acquiring a second electrical signal output by the MEMS microphone; and judging that the second electrical signal is an interference signal when within a substantially overlapping time range, the first electrical signal acquired reaches a preset first threshold value and the second electrical signal acquired meets a preset condition.
