Problems solved by technology

[0005] As mentioned in the previous case, the frame support body 110 is only used to support the fixed electrode 120, and there is no support body between the diaphragm 130 and the electrode 120, so it is impossible to prevent the electrode 120 and the diaphragm 130 from accidentally touching. body does not have a related design description
[0006] In addition, traditional electrostatic speakers are not capable of producing low-frequency (<500Hz) sounds, so most commercially available electrostatic speakers are equipped with dynamic speakers with low frequency response.

Embodiment Construction

[0042] The invention provides a support body design for a planar speaker, which solves the technical problem that the electrode and the diaphragm are in contact with each other due to electrostatic force and causes no sound, and at the same time improves the technical problem of insufficient low-frequency sound pressure of the traditional electrostatic speaker. Wherein, the structure of the supporting body is simple and can be manufactured in combination with existing technologies, and is suitable for mass production. The above-mentioned electrodes can be made of metal or other conductive materials, and holes can be opened on the electrodes so that sound can diffuse through the holes. The diaphragm at least includes an electret layer and conductive electrodes made of electret material.

[0043] If the conductive electrode is a metal electrode, in order not to affect the tension and vibration effects of the electret layer, it can be an extremely thin metal film electrode with a...

Abstract

The invention relates to a loudspeaker structure, which at least comprises a diaphragm, an opening electrode, a frame support body and a plurality of supporting bodies. The frame support body is used for forming the exterior structure of the loudspeaker structure and for fixing the diaphragm and an electrode on two corresponding sides. The supporting bodies are arranged between the non-opening area of the electrode and the diaphragm, and forms at least one annular geometric structure so as to prevent the diaphragm from being contacted with the electrode.

Description

technical field [0001] The present invention relates to the structure of an electrostatic speaker, and in particular to the design of the supporting member (Supporting Members) structure in a planar electrostatic speaker. Background technique [0002] The two most direct senses of human beings are vision and hearing, so for a long time, scientists have made great efforts to develop related components or system technologies. At present, electro-acoustic speakers are mainly classified into direct radiation type and indirect radiation type, and they can be roughly divided into dynamic, piezoelectric and electrostatic speakers according to the driving method. [0003] The current market for electrostatic speakers is mainly high-end (Hi-end) headphones and speakers. The working principle of traditional electrostatic speakers is to form two fixed electrodes (Electrode) with openings and a conductive vibrating film (Vibrating film). The capacitor, by supplying the diaphragm with D...
