Embodiment Construction

[0036] The electrostatic loudspeaker constructed by the present invention is composed of the following parts:

[0037]1. Electrostatic speaker front plate a1, electrostatic speaker rear plate a2: The plates are made of plastic or other insulating and non-insulating materials, and are designed according to the present invention with a sub-window frame. If the material is made of non-insulator, the surface needs to be coated with an insulating layer capable of withstanding 3-5 kV, and the edge of the plate needs to be connected to one end of the step-up transformer through a terminal. If the plate material is made of an insulator, a conductive layer needs to be coated on the side of the plate facing the diaphragm a3, and an insulating layer capable of withstanding 3-5 kV is added on the conductive layer. The coated conductive layer needs to pass through The binding post is connected to one end of the step-up transformer.

[0038] 2. Polarized diaphragm a3: The surface of the di...

Abstract

The invention discloses an electrostatic flat panel speaker, which comprises a front pole plate (a1), a rear pole plate (a2) and a diaphragm (a3) positioned between the front and rear pole plates (a1 and a2). The pole plate is an integrated pole plate consisting of an array plate which is formed by staggering a plurality of child windows (2) and grids (3) and enclosed by an outer frame (1). A conductive layer and one or more insulating layers covering the conductive layer are covered on the face, facing the diaphragm (3), of the pole plate; or the material of the pole plate is a conductive layer on which the insulated layer is covered; mirror symmetry is formed between all child windows (2) on the front pole plate (a1) and corresponding child windows (2) on the rear pole plate (a2), namely the child windows (2) on the front and rear pole plates (a1 and a2) are aligned correspondingly on the faces of the diaphragm (4); the diaphragm (4) is required to be fixed on the outer frame (1) of one pole plate; and the child windows (2), at corresponding positions on the two faces of the diaphragm (4), of the front and rear pole plates (a1 and a2) have correspondingly consistent shapes.

Description

technical field [0001] The invention relates to the design and manufacture of electro-acoustic equipment, in particular to the design and manufacture of a high-fidelity and high-sensitivity electrostatic loudspeaker. Background technique [0002] An electrostatic speaker is an electroacoustic component that produces high-quality audio playback. The sounding mechanism is two parallel polar plates, and a layer of polarizable diaphragm generally made of polymeric material is applied in parallel in the middle of the polar plates. When an audio voltage with a peak-to-peak value of thousands of volts is applied to the two plates, the alternating electrostatic field force formed by the audio voltage will push the polarized diaphragm to vibrate and produce sound, completing the electroacoustic conversion. Due to the extremely light weight of the diaphragm, which is generally equivalent to the mass of an air layer with a thickness of several millimeters, electrostatic speakers can ...
