Abstract

A MEMS microphone includes a backplate that has a plurality of open areas, and a diaphragm spaced apart from the backplate. The diaphragm is deformable by sound waves to cause gaps between the backplate and the diaphragm being changed at multiple locations on the diaphragm. The diaphragm includes a plurality of anchor areas, located near a boundary of the diaphragm, which is fixed relative to the backplate. The diaphragm also includes multiple vent valves. Examples of the vent valve include a wing vent valve and a vortex vent valve.
