Electret Condenser Microphone is divided into: audio microphone, infrasound microphone, ultrasonic microphone, array microphone, primary differential pressure microphone and so on
Its working principle is: as the electret film (usually in the form of 10 ~ 12 microns thick) on the free charge, as a result, when the effect of sound waves and make the diaphragm vibrates, capacitor between the poles had charge, then changed the static capacitance.The change of the capacitance results in the corresponding alternating voltage signal between the output terminals of the capacitor.
