Abstract
A micro electro-Mechanical System (MEMS) microphone includes a first back plate positioned on top of a first moving plate, wherein the first moving plate flexes in response to changes in air pressure caused by audio signals. The MEMS microphone also includes a valve comprising a valve moving plate, wherein a first end of the valve moving plate is fixedly attached to a MEMS die and the valve moving plate flexes in response to high sound pressure levels such that a second end of the valve moving plate enables airflow to prevent audio signal distortion.
