The diaphragm and backplane of the microphone are regarded as the two plates of the parallel plate capacitor. When the external bias voltage shown in the above figure is connected, the parallel plate capacitor composed of diaphragm and backplane begins to charge. The charging time may take a few seconds, which can be regarded as the startup time of the capacitive microphone.After charging, the parallel plate capacitor has charge accumulation, and the charge q = external bias voltage × Diaphragm backplane capacitance.

This makes the parallel plate capacitor work in constant charge mode.

When the acoustic pressure acts on the diaphragm, the distance d between the two plates of the parallel plate capacitor begins to increase or decrease. The relationship between the diaphragm backplane capacitance C and the distance d between the plates is as follows:
