Abstract
Provided is a diaphragm and a micro-electromechanical system (MEMS) microphone. The diaphragm includes a vibrating portion and a support structure. The support structure includes a cantilever portion. Lengths of the first and second anchoring portion both extend along a circumferential direction of the vibrating portion, and a length extension direction of the first anchoring portion is opposite to that of the second one. The lengths of the first and second anchoring portions both extend along the circumferential direction of the vibrating portion, and the length extension direction of the first anchoring portion is opposite to that of the second one, so that the first and second anchoring portions and the cantilever portion are connected in a T shape. A vibration displacement range of the diaphragm is larger, thereby improving sensitivity and compliance of the MEMS microphone.
