Title:
ELECTRONIC GENERATOR, NET CHARGE GENERATING DEVICE AND ELECTROSTATIC LOUDSPEAKER
Document Type and Number:
WIPO Patent Application WO/2019/218697
Kind Code:
A1
Abstract:
Provided by the present invention are a net charge generating device and an electronic generator used for the net charge generating device, and further provided is a diaphragm for use in an electrostatic loudspeaker. In existing technology, the electrostatic charge needed by an electrostatic loudspeaker diaphragm is injected by means of a high-voltage direct current power supply, and the large volume of a high-voltage direct current power supply makes the electrostatic loudspeaker unsuitable for use in portable electronic equipment, which is a disadvantage of the electrostatic loudspeaker. Provided in the present invention is a net charge generating device for replacing the high-voltage direct current power supply in the electrostatic loudspeakers of existing technology. The net charge generating device has a simple structure and is easily miniaturized, which greatly reduces the volume of an electrostatic loudspeaker designed therefrom and may meet the requirements of miniaturization and thinning of electrostatic loudspeakers in mobile portable devices.
