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.
