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 to make non-woven fabrics, dye and dry the above-mentioned fabrics, and then apply thermosetting Glue and drying treatment, then cutting and hot pressing molding, can be combined with the traditional paper sound cone, or the surface of the sound cone can be coated with glue, and then punched and edged to make the finished sound cone.

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, apply thermosetting glue and dry it, then cut the material and heat press to form it, which can be compared with the traditional paper sound cone For compounding, glue can also be applied to the surface of the sound cone, 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...
