Abstract

The embodiments of the present application provide a diaphragm in a sounding device, a preparation method thereof, and a sounding device. The method comprises the following steps: circularly arrangedgrooves on the inner side wall of the housing of the sounding device; sequentially adding a first solution and a second solution that are mutually incompatible in the housing of the sounding device, wherein the layered interface of the first solution and the second solution is located at the position of the grooves; causing polymerization of the first solution and the second solution at the layered interface to obtain a diaphragm, wherein the edges of the diaphragm are located in the grooves and fill the grooves. The preparation method provided by the embodiment of the present application cannot only avoid the problem of low product yield caused by the high temperature injection molding, but also avoid the toxic problem caused by the use of glue.

Description

technical field [0001] The present application relates to the technical field of electroacoustic conversion, and in particular to a diaphragm in a sound generating device, a preparation method thereof, and a sound generating device. Background technique [0002] Sound generators are electro-acoustic conversion devices commonly used in modern consumer electronics to convert electrical signals into sound. [0003] In the prior art, when the diaphragm in the sound generating device is assembled with the housing of the sound generating device, it is usually achieved by injection molding or glue bonding. [0004] However, the existing process faces problems such as low yield due to high injection molding temperature or toxic glue. Contents of the invention [0005] In view of the above problems, the present application is proposed to provide a diaphragm in a sound generating device, a manufacturing method thereof, and a sound generating device that solve the above problems or ...
