Due to the free charge distributed on the electret film. When the acoustic wave causes the displacement of the electret film due to vibration; The distance between the two plates of the capacitor is changed, resulting in the change of the capacitance. Since the number of charges on the electret remains constant all the time, according to the formula: q = Cu, when C changes, it will inevitably cause the change of voltage u at both ends of the capacitor, so as to output electrical signals and realize acoustic electrical conversion. In fact, the internal structure of electret microphone is shown in Figure 3.What is the sound principle of microphoneThe microphone transmits the sound vibration to the diaphragm of the microphone and pushes the magnet inside to form a changing current. In this way, the changing current is sent to the rear sound processing circuit for amplification.
