Hyperelastic silica gel vibrating diaphragm materials

Abstract

The present invention discloses hyperelastic silica gel vibrating diaphragm materials. The hyperelastic silica gel vibrating diaphragm materials are made of silicone rubber and other auxiliary materials for mixing, upper and lower isolation membranes form a sandwich structure, a sandwich layer formed through hot press molding is the silica gel vibrating diaphragm materials through the hot press molding. The hyperelastic silica gel vibrating diaphragm materials are used for vibrating diaphragms of a loudspeaker and a receiver, are low in elasticity modulus and good in damping effect, and the made loudspeaker product is lower in the resonant frequency F0 compared to a loudspeaker made of other traditional materials, is better in the low-frequency distortion rate, and is lower than 10%.

Description

technical field [0001] The invention relates to a superelastic silicone diaphragm material. Background technique [0002] With the development of electronic products towards lighter and thinner, the volume of receivers and speakers must also become thinner and shorter. With the reduction of the speaker volume, maintaining and improving the sound quality and volume of the speaker has become a research and development goal pursued by manufacturers. As we all know, the diaphragm is one of the components most related to sound quality and volume in the speaker. The material selection of the diaphragm will directly affect the sound quality and volume performance of the speaker. Especially in today's micro-speaker architecture, the material of the diaphragm is almost the most critical factor affecting the sound quality and volume of the speaker. [0003] In order to improve the sound reproduction effect and optimize product performance, people have made many attempts to explore t...

For example, patent CN201520839998 proposes a silica gel diaphragm and a loudspeaker manufacturing method, a patent CN201320878219 describes a composite diaphragm and a diaphragm-applied loudspeaker manufacturing method, and the patent 201420142187.4 proposes a loudspeaker diaphragm. The above three utility model patents all propose The application of silica gel in the diaphragm, but the silica gel diaphragms proposed in the above utility model patents are all silica gel composite diaphragms made of PEEK or other materials and silica gel materials. The silica gel composite diaphragms described in the above patents have general performance. The realization process is complicated, the cost is high, and it is difficult to realize commercial production
