Abstract
A microphone chip and a microphone are provided. The microphone chip includes a substrate and a capacitive system disposed on the substrate. The capacitive system includes a diaphragm and a back plate spaced from the diaphragm, and there is an air spacing defined between the diaphragm and the back plate. The diaphragm includes an inner membrane portion, at least one outer membrane portion, and at least one supporting portion. The microphone chip further includes a supporting member. In an operating state, the inner membrane portion is adsorbed on the supporting member, and the supporting member is configured to divide the inner membrane portion into at least two regions. The diaphragm in the operating state is divided by the supporting member into a plurality of floating regions separated from each other, such that the rigidity of the diaphragm can be effectively adjusted and enhanced according to requirements.
