Abstract
The present invention provides a capacitive microphone including a MEMS microphone. In the microphone, the movable or deflectable membrane/diaphragm moves in a lateral manner relative to the fixed backplate, instead of moving toward/from the fixed backplate. The squeeze film damping is substantially avoided, and the performances of the microphone is significantly improved.
