Vibrating diaphragm for electro-acoustic system and preparation method of vibrating diaphragm

Abstract

The invention belongs to the technical field of acoustic materials and discloses a vibrating diaphragm for an electro-acoustic system. The vibrating diaphragm is prepared from a rubber mixed compound, wherein the rubber mixed compound is prepared by mixing raw rubber, a filling and an additive; the vibrating diaphragm is prepared from the rubber mixed compound through vulcanization; the rubber mixed compound is prepared by mixing raw rubber, the filling and the additive; the raw rubber contains nitrile groups and / or ester groups; the filling contains Si-O-Si groups; the additive contains a vulcanizing agent. The invention simultaneously provides a preparation method of the vibrating diaphragm. According to the preparation method, a rubber material is utilized for replacing a multi-layer resin composite film raw material to prepare the vibrating diaphragm, and distortion can be reduced by virtue of internal friction of the rubber, so that the nature of sound can be well restored by the prepared vibrating diaphragm; and besides, the material cost is low, the processing process is simple, the forming consistency is good, and the production efficiency can be substantially improved.

Description

technical field

[0001] The invention relates to the technical field of acoustic materials, in particular to an electroacoustic system material and a preparation method thereof. Background technique

[0002] Electro-acoustic devices refer to devices that convert electricity and sound, which use electromagnetic induction, electrostatic induction or piezoelectric effects to complete electro-acoustic conversion, mainly including speakers, earphones, microphones, cartridges, etc. As human beings enter the information age, information dissemination is inseparable from "seeing" and "listening", and "listening" cannot be separated from the electroacoustic industry. The adjustment of the electronic industry in today's world, the rapid development of information technology and communication technology have had a huge impact on the development of the electroacoustic industry, and the industry has developed rapidly. Both the domestic market and the international market show the charact...
