Abstract

The invention discloses a diaphragm and a diaphragm assembly, and preparation methods thereof. The preparation method for the diaphragm comprises the following steps: adding a coupling agent into silicone rubber and subjecting the silicone rubber and the coupling agent to physical coupling; adding a curing agent into the silicone rubber and allowing the curing agent to be uniformly dispersed in the silicone rubber; and subjecting the silicone rubber with the curing agent and the coupling agent to injection molding so as to form the diaphragm. The preparation method for the diaphragm is simple in process, easy to operate and suitable for large-scale production. Moreover, the preparation method can effectively improve the elasticity, structural strength and tear strength of the diaphragm.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, and more particularly, to a diaphragm, a diaphragm assembly, and a method for preparing the diaphragm and the diaphragm assembly. Background technique [0002] In the prior art, the diaphragm used for the loudspeaker is usually formed by direct thermocompression of plastic or silicone rubber. The structural strength and tear resistance of these diaphragms are relatively low. During vibration, the diaphragm is easily broken. [0003] In addition, due to the low structural strength of the diaphragm, the diaphragm is prone to split vibrations during large-amplitude vibrations. The sound from the speakers is poor. Contents of the invention [0004] In order to solve the above technical problems, embodiments of the present invention provide a diaphragm, a diaphragm assembly, and a method for manufacturing the diaphragm and the diaphragm assembly. [0005] According to a first ...
