The distance between the two plates changes due to vibration, that is, the capacitance C changes, while the electric quantity Q does not change, which will cause the change of voltage. The magnitude of voltage change reflects the strength of external sound pressure, This voltage change frequency reflects the frequency of external sound, which is the working principle of electret microphone.Capable of converting sound directly into electrical energy signalsCapacitive microphone is designed by using the principle of capacitive charge and discharge between conductors, using ultra-thin metal or gold-plated plastic film as vibrating film to induce sound pressure, so as to change the static voltage between conductors, directly convert it into electric energy signal, and obtain practical output impedance and sensitivity through electronic circuit coupling.
