electrostatic loudspeaker

The structure of the electrostatic loudspeaker is the same as that of a capacitor. Here, the loudspeaker diaphragm can lie between the two electrodes

and be controlled by the electric field; however, it can also be one of the electrodes. In electrostatic operation, two electrodes with equal charge repel each other, while two electrodes with unequal charge attract

each other.If a voltage

is applied to the electrodes of an electrostatic loudspeaker, the voltage level is a measure of the deflection of the electrodes. A high voltage causes a large deflection, a low voltage causes a small deflection, and a reversed-polarity voltage causes a deflection in a different direction. The force acting on the electrodes depends on the electrostatic field constant, the plate area and is proportional to the square of the voltage.

Construction of the electrostatic loudspeaker

Electrostatic loudspeakers are often designed as tweeters. However, with the electrostats, there is a loudspeaker design that covers the complete audible frequency range.
