Problems solved by technology

[0005] In order to achieve the design purpose of the present invention, the present invention has gone through several years of repeated trials and tests on the material selection of the voice coil former, and found that glass fiber cloth and resin are used as the base material of the voice coil former, and are formed and removed after high temperature curing. The epoxy resin cloth voice coil frame made by the mold not only has a smooth appearance, good strength, and no loss of circle, but also has excellent insulation performance and is easy to install, which solves the problem that the background technology cannot solve, and it can vibrate freely in the speaker and has good elasticity. , reducing the trouble of the installers, fundamentally making up for the lack of voice coils for many years

Embodiment 1

[0008] Embodiment 1: with reference to attached figure 1 . The voice coil is made of epoxy resin cloth, the coil 1 is wound on the voice coil frame 2, and the voice coil frame 2 is a one-time molded epoxy resin cloth.

Embodiment 2

[0009] Embodiment 2: the preparation method of epoxy resin cloth voice coil frame, first on voice coil frame mold, be coated with wax, then glass fiber cloth is wrapped on voice coil frame mold and be coated with resin, then plastic film is wrapped on After it is put on, it is cured at a high temperature of 160°C to 200°C and demolded at one time to form an epoxy resin cloth voice coil frame. Resin is coated between the glass fiber cloth and the glass fiber cloth.

Abstract

The present invention is voice coil made with epoxy resin cloth and through once formation. The voice coil has the advantages of smooth appearance, high strength, high insulating performance, easy installation, free vibration in loudspeaker and high elasticity and good acoustic effect.

Description

Technical field: [0001] The invention relates to the use of epoxy resin cloth for making a voice coil frame and a voice coil, and belongs to the field of voice coil product manufacturing. Background technique: [0002] Publication number CN1172185A, titled "A Production Method for Voice Coil Paper", which includes hot melt adhesive coating, slitting and other processes, is characterized in that before coating, the paper substrate is subjected to super calendering treatment, increasing The tightness and elasticity of the paper substrate, and the paper substrate is in the shape of a cylinder or a disc in various processes such as super calendering, hot melt adhesive coating, and slitting. The existing shortcomings: first, poor strength, easy to lose roundness, second, easy to be affected by moisture deformation and affect the performance of the voice coil, third, poor elasticity, troublesome installation. [0003] At present, the voice coils sold on the market and used by ele...
