Abstract

Embodiments of the present application provide a diaphragm in a sound generating device, a manufacturing method thereof, and a sound generating device. Wherein, the method includes the following steps: the inner side wall of the shell of the sound generating device is provided with a groove, and a first solution and a second solution that are incompatible with each other are sequentially added into the shell of the sound generating device, and the first The layered interface of the solution and the second solution is located at the position of the groove; the polymerization reaction of the first solution and the second solution occurs at the layered interface to obtain the diaphragm, the The edges of the diaphragm are located in the groove and fill up the groove. The preparation method provided in the embodiment of the present application can not only avoid the problem of low product yield caused by high-temperature injection molding, but also avoid the problem of toxicity caused by the use of glue.

Description

Technical field

[0001] This application relates to the field of electro-acoustic conversion technology, and in particular to a diaphragm in a sounding device, a preparation method thereof, and a sounding device.Background technique

[0002] The sound generating device is an electro-acoustic conversion device commonly used in modern consumer electronic products for converting electrical signals into sound.

[0003] In the prior art, when the diaphragm of the sound generating device is assembled with the housing of the sound generating device, it is usually realized by injection molding or glue bonding.

[0004] However, this existing process faces problems such as low yield due to high injection temperature or poisonous glue.Summary of the invention

[0005] In view of the above-mentioned problems, the present application is proposed to provide a diaphragm in a sounding device that solves the above-mentioned problems or at least partly solves the above-mentioned problems, and a preparation method ther...
