Zooming in to a MEMS microphone on an integrated circuit board from a mobile telephone. MEMS is a microelectromechanical system, comprising micrometre-scale components in a moving mechanical system. The microphone comprises a diaphragm and a flat plate, both of which act as the plates of a capacitor. As sound waves cause the diaphragm to vibrate, the changing capacitance produces an electric signal. | |
