Abstract

The present invention discloses a non pulp base material speaker sound cone and a producing process thereof. The base material of the speaker sound cone is nonwoven fabric which has the percent weight proportion: 0 to 30 of special ceramic fiber, 0 to 30 of carbon fiber, 0 to 30 of bulletproof fiber, 0 to 20 of nylon fiber, and 50 to 95 of cotton fiber; the base material of the speaker sound cone can also be woven fabric which has the percent weight proportion: 0 to 30 of special ceramic fiber, 0 to 100 of glass fiber, 0 to 100 of carbon fiber, and 0 to 100 of bulletproof fiber. The producing process is that processing into fabric-> dyeing-> sizing-> material cutting-> thermoforming-> (combination)-> (sizing)-> die cutting and edge lapping. The present invention has the advantages of beautiful appearance, superior electroacoustic performance, environmental protection, wide adaptation range, etc.

Description

Non-paper Pulp Substrate Loudspeaker Sound Basin And Manufacture Process

One, technical field

The present invention relates to a kind of loudspeaker cone and manufacturing process thereof, especially relevant with Non-paper Pulp Substrate Loudspeaker Sound Basin And Manufacture Process.

Two, background technology

Along with developing rapidly of electronics industry, people are more and more higher to the requirement of hearing effect, and the electroacoustic conversion of various application scenarios all develops to the high, precision and frontier direction.The sound basin is the key functional members of loud speaker sounding, and its electroacoustic property directly has influence on the acoustical behavior of loud speaker.With paper pulp is main traditional sound basin of making, can not satisfy the requirement of modern high-grade loud speaker, and will expend natural timber paper pulp, also produces paper pulp wastewater, contaminated environment in the manufacturing process.

Three, summary of the invention

The purpose of this invention is to provide a kind of employing woven cloth or nonwoven cloth material is base material, good looking appearance, and electroacoustic performance is superior, and no paper pulp wastewater pollutes, Non-paper Pulp Substrate Loudspeaker Sound Basin And Manufacture Process applied widely.

For achieving the above object, technical solution of the present invention is: the base material of non-paper pulp base material loudspeaker cone is a kind of nonwoven fabrics, the proportioning of per hundred parts of weight of this nonwoven fabrics is: special cermacis fiber 0-30, carbon fiber 0-30, ballistic fiber 0-30, nylon fiber 0-20, cotton fiber 50-95, wherein special cermacis fiber and ballistic fiber are not 0 simultaneously in the proportioning of per hundred parts of weight.

The base material of non-paper pulp base material loudspeaker cone is a kind of woven cloth, the proportioning of per hundred parts of weight of this woven cloth is: special cermacis fiber 0-30, glass fibre 0-100, carbon fiber 0-100, ballistic fiber 0-100, wherein ballistic fiber proportioning lower limit does not comprise lower limit itself.

A kind of manufacturing process of non-paper pulp base material loudspeaker cone is: a) be processed into nonwoven fabrics or woven cloth cloth by said ratio, b) above-mentioned cloth is dyeed and dry, c) applying glue, above-mentioned cloth is applied thermosetting glue and dried, d) cut out material and hot-forming, e) carry out compoundly with traditionally on paper sound basin, f) gluing is carried out on sound basin surface, g) die-cut and scrap (bridge) is made sound Pengcheng product.

The present invention is owing to adopted above-mentioned technical solution, thereby have following beneficial effect: (one) is appearance looks elegant, widely applicable: product color, surface weave floral designs are various, the appearance requirement that can adapt to country variant, different nationalities, product is applicable to rise various medium-to-high grade loud speakers more than the sound to 20 inch from ball; (2) be that environment protecting is good: the present invention does not consume the nature wood pulp, adopts the heat pressing process straight forming, does not produce the paper pulp wastewater contaminated environment, is a kind of environmentally friendly machine; (3) be that tone color is abundant, have superior electroacoustic performance: product strength is big, good rigidly, and hardness is big, owing to adopt high Young's modulus materials such as special cermacis fiber, glass, carbon fibre, add that high-strength adhesive is hot-forming, product strength, elasticity, rigidity all are better than common sound basin, acoustic propagation velocity is greatly greater than common sound basin, cut apart vibration and be significantly smaller than common sound basin,, can bear high-power simultaneously so the distortion factor obviously descends; (4) be that hearing effect is good: owing to adopt rational formula and manufacture craft, so have superior internal damping and internal loss characteristic, improve tonequality and distortion and play good effect, its frequency response is wide after making loud speaker, frequency response curve rises and falls little, distortion factor is low, and tone color is abundant, has good hearing effect; (5) be superior weather resistance: because special cermacis, glass, carbon fibre etc. have than the better protection against the tide of paper pulp, water resistance and stable temperature coefficients, have good ageing-resistant performance, so the sound basin in various environment, use, stable and reliable for performance; (6) be of many uses: product of the present invention can be widely used in high-fidelity, high-grade loud speaker of high-power modern times, as professional sound equipments such as stadiums, music halls, high-fidelity such as radio station, recording studio is monitored sound equipment, high-grade automobile audio, multimedia sound equipment and high-grade home audio etc.

Four, embodiment

Below embodiments of the invention are described in further detail.

Embodiment 1: get 10 kilograms of special cermacis fibers, 5 kilograms on carbon fiber, 5 kilograms of ballistic fibers, 10 kilograms of nylon fibers, cotton fiber mix for 70 kilograms makes the nonwoven cloth, above-mentioned cloth is dyeed and drying, apply thermosetting glue and dried again, cut out material and hot-forming then, can carry out compound with traditionally on paper sound basin, also can carry out gluing to sound basin surface, die-cut then and scrap (bridge) is made sound Pengcheng product.

Embodiment 2: get 20 kilograms of ceramic fibres, cotton fiber mixes for 80 kilograms makes the nonwoven cloth, and all the other are with embodiment 1.

Embodiment 3: get 50 kilograms in glass fibre, 50 kilograms on carbon fiber, mixed weaving becomes cloth, above-mentioned cloth is dyeed and drying, apply thermosetting glue and dried again, cut out material and hot-forming then, can carry out compound with traditionally on paper sound basin, also can carry out gluing to sound basin surface, die-cut then and scrap (bridge) is made sound Pengcheng product.

Embodiment 4: get 80 kilograms of ballistic fibers, 20 kilograms of mixed weavings of carbon fiber are made knitted or woven fabrics, and all the other are with embodiment 3.
