    摘要: 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.

    摘要: Devices related to digital MEMS loudspeakers are discussed. Such devices may include an air pressure source, MEMS valves coupled to the air pressure source, and an audio modulator coupled to the MEMS valve to receive an audio signal and to control the MEMS valves via a modulation signal to provide an acoustic output.
