Embodiment 1

[0014] Example 1: 45 parts of methyl silicone rubber, 10 parts of white carbon black, 25 parts of methyl hydrogen-containing silicone oil, 5 parts of hydroxyl silicone oil, 5 parts of hydrogen-containing silicone oil, 2 parts of organotin and 1 part of toner Separately mix, stir evenly, apply on the isolation film on the coating machine, the coating thickness is 75um, and then attach the isolation film to make a sandwich structure, after 180 degrees, heat press for 3-5 minutes to form, take out the sandwich layer to get The thickness is 70um silicone rubber diaphragm material. Compared with other traditional materials, the loudspeaker products made of this material have a lower resonance frequency F0; the low-frequency distortion rate is 8%.

Embodiment 2

[0015] Example 2: 45 parts of methyl vinyl silicone rubber, 10 parts of white carbon black, 25 parts of methyl hydrogen-containing silicone oil, 5 parts of hydroxyl silicone oil, 5 parts of hydrogen-containing silicone oil, 2 parts of platinum complex and 1 part Mix the coloring components, stir evenly, and apply it on the isolation film on the coating machine. The core layer can be obtained with a thickness of 60um silicone rubber diaphragm material. Compared with other traditional materials, the loudspeaker products made of this material have a lower resonance frequency F0; the low-frequency distortion rate is lower than 9%.

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...
