Embodiment 1

[0009] Embodiment 1: get 10 kilograms of special ceramic fibers, 5 kilograms of carbon fibers, 5 kilograms of bullet-proof fibers, 10 kilograms of nylon fibers, and 70 kilograms of cotton fibers are mixed evenly to make non-woven fabrics, and the above-mentioned fabrics are dyed and dried as required, and then applied Add thermosetting glue and dry it, then cut the material and heat press to form it. It can be compounded with traditional (paper, etc.) sound cones as needed, or the surface of the sound cone can be glued as needed, and then punched and edged to make a sound. Finished basin.

Embodiment 2

[0010] Embodiment 2: get 20 kilograms of ceramic fibers, 80 kilograms of cotton fibers are mixed and made into non-woven cloth, and all the other are the same as embodiment 1.

Embodiment 3

[0011] Example 3: Take 50 kg of glass fiber and 50 kg of carbon fiber, mix and weave it into cloth, dye and dry the above cloth as required, then apply thermosetting glue and dry, then cut the material and heat-press molding, which can be combined with traditional (Paper, etc.) sound cones are compounded, and the surface of the sound cone can also be glued as required, and then punched and edged to make the finished sound cone.

Abstract

This invention disclose an unpulp basic material loudspeaker cone and its manufacturing technology. The basic material of the cone is an unwoven cloth, proportion of its weight percentage is: specific ceramic fiber 0-30, carbon fiber: 0-30, anti-bomb fiber 0-30, nylon fiber 0-20, cotton fiber 50-95. Its basic material can be woven cloth with the proportion of : specific ceramic fiber 0-30, glass fiber 0-100, carbon fiber 0-100, anti-bomb fiber 0-100. The manufacturing technology is :to be processed to cloth->dying->gluing->cutting the material to be formed by hot pressure->(compound)->(gluing)->cutting edge->lapping edge.

Description

1. Technical field [0001] The invention relates to a loudspeaker cone and a manufacturing process thereof, in particular to a non-pulp base material loudspeaker cone and a manufacturing process thereof. 2. Background technology [0002] With the rapid development of the electronic industry, people have higher and higher requirements for listening effects, and the electroacoustic conversion in various applications is developing in the direction of high, precise and sharp. The sound cone is the key functional part of the sound of the speaker, and its electroacoustic characteristics directly affect the acoustic performance of the speaker. The traditional sound basin mainly made of pulp can no longer meet the requirements of modern high-end speakers, and it consumes natural wood pulp, and pulp waste water is generated during the production process, polluting the environment. 3. Contents of the invention [0003] The object of the present invention is to provide a non-pulp bas...
