Description

Technical Field

[0001] The present application relates to the field of audio, and in particular to an electrostatic audio device. Background Art

[0002] Electrostatic sound refers to a speaker in which an extremely thin diaphragm moves back and forth under the action of electrostatic force, which is different from an electric speaker that relies on electromagnetic force to move the diaphragm back and forth. The theoretical distortion of electrostatic sound is only about 0.02%, which is much lower than that of traditional electric speakers (distortion is usually as high as 3%). It is a HIFI (HIGH FIDELITY) speaker.

[0003] At present, electrostatic speakers are usually driven by high voltage. Electrostatic speakers need a separate high-voltage driving device to drive them, which is troublesome. In addition, the driving device needs to move with the movement of the electrostatic speaker, which is very inconvenient. Electrostatic speakers are integrated structures. When one of the components is damaged, it needs to be replaced as a whole.

[0004] Therefore, how to solve the above technical problems should be the focus of technical personnel in this field. Utility Model Content

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] As described in the background technology section, currently the electrostatic sound is an integrated structure and requires a separate high-voltage driving device to drive it. The driving process is troublesome, and the driving device needs to move with the movement of the electrostatic sound, which is very inconvenient.
