Cone of thin speaker

Abstract

The invention relates to a cone of a thin speaker, comprising a cone edge and a cone body. The cone is characterized in that the cone body is annular and provided with a cone central hole in the center, the cone edge central hole is in the shape of a wave having a central hole wave crest and a central hole wave trough which respectively radially extend towards the edge by taking the center of the cone body as a base point, and a body wave crest surface and a body wave trough surface are formed on the surface of the cone body; the cone has an annular edge which comprises a cushion edge and a deflector ring the shape of which is the extension of the shaped of the cone body which radially extends towards the edge from the center, and the deflector ring has a deflector ring wave crest surface and a deflector ring wave trough surface; the cone body is arranged on the cone edge, and the lower surface of the body wave crest surface and the lower surface of the body wave trough surface respectively cling to the upper surface of the deflector ring wave crest surface and the upper surface of the deflector ring wave trough surface. The invention has reasonable structure, low degree of distortion, excellent tone quality, preparation by traditional materials, convenient material obtaining, better rigidity, simple forming process and low cost.

Description

technical field [0001] The invention belongs to the technical field of sound and electricity, and relates to a loudspeaker component, in particular to a thin loudspeaker cone. Background technique [0002] The sound cone is also called the diaphragm or vibration plate, which is an important part of the speaker. Now the high-power speakers used in LCD, PDP and other flat-panel video equipment generally use flatter speakers in order to make the structure of the entire speaker unit thinner. Basin stand and cone. However, the traditional sound cone adopts a conical structure with a high overall height, which does not meet the requirements of thinning the speaker; while the flat sound cone can effectively solve the problem of thinning. General flat-panel cone materials are mainly composed of honeycomb panels, foamed metals, filled foamed plastic structures, NXT diaphragms, B.E.S diaphragms and other new and composite materials. The advantages are light, thin, good rigidity, and ...

AI Technical Summary

Problems solved by technology

However, most of these flat-panel sound cone materials rely on imports, and require multiple materials to be composited. The process is complex and expensive, which is not conducive to the large-scale adoption of speakers for flat-panel TVs such as LCD and PDP.
