Problems solved by technology

In order to pursue better sound quality, the diaphragms are thin and rigid. The market began to study metal diaphragms such as titanium alloy / beryllium alloy. The technical solutions of traditional alloy materials are relatively heavy and weak in corrosion resistance. Dirty foreign objects and cleaning are produced during the process. The degree difference will cause many defects in the subsequent processing, and the bonding force with PeeK is poor, the defect is high, and the price is high

Abstract

The invention discloses a manufacturing method of a light and thin alloy vibrating diaphragm, which comprises the following steps of: (a) pre-cleaning an alloy material, and softening, separating anddissolving pollutants on a workpiece by adopting an organic solvent coating and rolling method; (b) punching a product belt with a required structure by using a punching forming die; (c) removing oiland an oxide layer by using an organic solvent; (d) cleaning to peel off dirt on the surface of the workpiece; (g) secondary processing of the product from the product strip into a single piece. According to the light and thin alloy diaphragm manufacturing method, a small light and thin alloy anti-corrosion protection and decorative diaphragm production process is provided, the diaphragm is light,thin, high in rigidity and anti-corrosion protection, high in combination stability and decorative, the process method is relatively simple, operation is convenient, the yield is high, the cost is reasonable, and popularization and application are facilitated. The method is an efficient production process method of the light and thin alloy diaphragm with corrosion protection and decoration.

Description

Technical field [0001] The present application relates to a method for producing a diaphragm, and more particularly to a method of manufacturing a lightweight alloy diaphragm. Background technique [0002] Headphones can listen to wonderful music, with high quality horn units inside the headphones. There are many factors affecting the quality of the speaker unit, and the vibrating film is one of the most critical components that the speaker unit can make a good quality. [0003] Most of the market use plastic vibrating membranes (such as PET / PEN / PEEK ...) and other vibrating films (eg, xenophosm / biological vibrating membrane / paper vibrating film ...). [0004] Under the capability of maximum vibration, the thinner the thickness of the diaphragm is, the better the low frequency. If the rigidity of the vibration of the diaphragm is increased and the effective radiation area of ​​the increase of the diaphragm is increased, there is a certain improvement of the damping effect...
