Abstract

The invention discloses a diaphragm preparation method and a sounding device. The preparation method includecomprises the steps of adding a flaky filler into silicone rubber, and uniformly mixing theflaky filler with the silicone rubber; molding the mixed material to obtain a diaphragm. The diaphragm preparation method and the sounding device have the advantages that through modification of the silicone rubber by the flaky filler, the mechanical strength and the damping performance of the diaphragm can be enhanced, and accordingly, the listening performance of the sounding device can be improved.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a method for preparing a diaphragm and a sounding device. Background technique [0002] In the sound generating device, the diaphragm is a very important part, and its manufacturing material and process directly affect the acoustic effect of the sound generating device. The existing silicone diaphragm has good temperature resistance and thickness uniformity, and can improve the acoustic performance of the sound generating device during use. However, the mechanical strength of this silicone diaphragm is relatively low, and the diaphragm is prone to rupture during continuous vibration. Moreover, the damping performance of this silicone diaphragm is relatively poor, which cannot meet the requirements of the product for listening performance. Therefore, it is very necessary to develop a new diaphragm preparation technology to overcome the defects in the prior art. ...
