Abstract

The invention discloses a diaphragm for a sounding device and a preparation method of the diaphragm. The preparation method comprises the following steps: adding a carbon fiber material into a siliconrubber raw material and uniformly mixing the carbon fiber material and the silicon rubber raw material; shaping the mixed materials to form a composite material film layer. In the preparation method,by adding the carbon fiber material into silicon rubber, the tearing strength, the elastic modulus, the heat resistance, the damping performance and the like of the formed diaphragm can be obviouslyimproved.

Description

technical field [0001] The invention relates to the technical field of material preparation, and more specifically, to a diaphragm used for a sound generating device and a preparation method thereof. Background technique [0002] The main chain of silicone rubber is composed of silicon-oxygen bonds with high bond energy, and the side chains are organic groups. Silicone rubber combines the characteristics of organic matter and inorganic matter, and has the advantages of excellent high and low temperature resistance, weather resistance, hydrophobicity and good resilience. Therefore, the diaphragm made of silicone rubber can make the speaker obtain excellent thermal stability and good waterproof performance. [0003] However, due to the symmetrical structure of silicone rubber and high tacticity, the steric hindrance of the symmetrically substituted methyl groups is small, resulting in low damping properties. In this way, the product distortion of the silicone rubber diaphrag...
