Abstract
A drive circuit is provided, which is used for driving an electrostatic film actuator. The drive circuit includes an input end, an isolation capacitor and a diode. The input end is used for receiving an input signal. The isolation capacitor includes a first end and a second end. The first end is electrically connected to the input end, and the second end is electrically connected to the electrostatic film actuator. The diode is connected between a working voltage end and the second end in a forward-bias direction, and an output signal is generated at the second end to drive the electrostatic film actuator.
