It can be seen from (Formula 1) that the electrostatic force is proportional to the product of the bias voltage and the audio voltage, and inversely proportional to the distance between the hole electrode plate and the electret diaphragm. Therefore, if the electrostatic speaker H can provide a high resident power at the same distance, the audio AC voltage can achieve the required electrostatic force with a relatively low voltage. In this implementation, the nano-hole electret piezoelectric composite material can provide a static force formula of a few hundred to an upper volt.

It can be reduced to ten volts' thus improving the courtesy of the planar speaker of the present embodiment. σ A According to the foregoing principle, the electret diaphragm is subjected to a push-pull electrostatic force under the positive 'negative bias of the two apertured electrode plates, causing the vibration of the electret to select the membrane and compressing the surrounding air.
