Epoxy resin cloth coil and its making process

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

[0001] Technical field: The present invention relates to the use of epoxy resin cloth for making voice coils, which 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 electroacoustic fact...

Examples

Embodiment 1

[0007] Embodiment 1: with reference to attached figure 1 . The epoxy resin cloth voice coil, the coil (1) is wound on the voice coil (2), and the voice coil (2) is a one-time molded epoxy resin cloth.

Embodiment 2

[0008] Embodiment 2: the preparation method of epoxy resin cloth voice coil, at first be coated with wax on the voice coil mold, then wind glass fiber cloth on the voice coil mold and be coated with resin, after plastic film is wrapped on it again , After curing at a high temperature of 160 ° C to 200 ° C and demolding once, the epoxy resin cloth voice coil is formed. Resin is coated between the glass fiber cloth and the glass fiber cloth.
