Abstract

An MEMS microphone is provided, including a base having a back cavity, and a capacitor system disposed on the base, the capacitor system including a backplate and a diaphragm disposed oppositely to the backplate. The diaphragm includes a body portion and a plurality of venting portions connected to the body portion, each of the plurality of venting portions includes a venting aperture penetrating through the diaphragm and a membrane flap partially fixed to the diaphragm and located in the venting aperture. The MEMS microphone further includes an insulation connecting pillar having one end fixedly connected to the backplate and another end fixedly connected to the membrane flap. Compared with the related art, the venting portion is fixedly connected to the backplate through the insulation connecting pillar, so that the venting portion is not easily warped, thereby improving reliability of the MEMS microphone.
