Manufacturing method for preventing damper deformation

Abstract

The invention relates to a manufacturing method for preventing damper deformation. The manufacturing method comprises a providing step, an impregnating step, a drying step, a hot-pressing formation step and a cutting step, wherein a substrate is provided in the providing step; the substrate is provided with at least one pre-formed damper formation area; furthermore, the providing step is matched with the hot-pressing formation step; the dried substrate is put in a hot-pressing mould; after the substrate is warmed, pressurized and moulded, a brim part is formed on the outer periphery of the damper formation area; due to the brim part, the damper formation area can averagely bear hot-pressing formation shrinkage force; furthermore, the position of the damper formation area is kept same; the problem of unequal deformation of the substrate due to different shrinkage force can be avoided; and finally, a damper is obtained after the cutting step. Thereby, the damper having good quality can be manufactured through the manufacturing method in the invention.

Description

technical field [0001] The present invention relates to a manufacturing method of elastic waves for loudspeakers, in particular to a manufacturing method for preventing deformation of elastic waves. Background technique [0002] Press, Damper is one of the most important components in the horn or speaker structure. The damper with better elasticity and toughness characteristics not only provides better output power and audio characteristics of the horn or speaker, but also the speaker or speaker. When speaker manufacturers manufacture speakers or speakers, the basis of quality management can effectively increase the service life of speakers or speakers. [0003] However, the traditional manufacturing method of forming elastic waves mainly uses cotton cloth as the basic material, and then dips the cotton cloth in liquid synthetic resin to absorb the synthetic resin in the fibers of the cotton cloth, and the cotton cloth absorbing the synthetic resin will be woven after drying...

AI Technical Summary

Problems solved by technology

[0005] First, due to the elasticity of the cotton cloth, when each elastic wave shape is shrunk and formed from a flat elastic wave forming block, it will also be formed in waves due to the different shapes of the elastic waves when it is heated and pressed by the mold. The shrinkage force of the overall forming of the elastic wave is not uniform, so that the problem of incomplete formation of the elastic wave occurs

[0006] Second, when the elastic wave shrinks from a flat shape, the longitudinal and transverse fiber lines of the elastic wave body will be pulled by the shrinkage force and will also break, even causing the cotton cloth to be torn
