Abstract
A micro-electro-mechanical system (MEMS) microphone is provided. The MEMS microphone includes a substrate, a backplate, an insulating layer, and a diaphragm. The substrate has an opening portion. The backplate is disposed on a side of the substrate, with protrusions protruding toward the substrate. The diaphragm is movably disposed between the substrate and the backplate and spaced apart from the backplate by a spacing distance. The protrusions are configured to limit the deformation of the diaphragm when air flows through the opening portion.
