A certain permanent charge (q) is injected into the polymer polarization film during production. Since there is no discharge circuit, the amount of charge is constant. Under the action of sound wave, the polarization film vibrates with the sound, so the distance from the back electrode also changes, that is, the capacitance between the locking polarization film and the back electrode changes with the sound wave.

We know that the formula for the charge on the capacitor is q = C & MES; 5. On the contrary, v = q / C is also true. The total charge of the electret is constant. When the plate retreats under the acoustic pressure, the capacitance decreases and the voltage between the two poles of the capacitor will increase inversely. On the contrary, when the capacitance increases, the voltage between the two poles of the capacitor will decrease inversely. Finally, take out the voltage at both ends of the capacitor through the field effect with very high impedance and amplify it at the same time, and we can get the voltage corresponding to the sound. As FET is an active device, it needs a certain bias and current to work in the amplification state. Therefore, electret microphones need to add a DC bias to work.
