Abstract

The invention discloses a vibrating diaphragm preparation method and a vibrating diaphragm. The preparation method comprises the steps: adding a mica material into liquid silica gel and evenly mixing;performing cross-linking formation on the mixed materials to obtain the vibrating diaphragm. The liquid silica gel is modified by the mica material, so that the damping capacity and the elasticity modulus can be obviously improved, partition vibration of the vibrating diaphragm can be obviously reduced, and noise can be absorbed; thus, audition performance of a sound production device is improved, F0 (resonant frequency) of the vibrating diaphragm is adjusted, nonlinear distortion of the vibrating diaphragm is reduced, and the phenomenon of vibrating diaphragm rupture is reduced.

Description

technical field [0001] The present invention relates to the technical field of electroacoustic conversion, and more specifically, to a method for preparing a diaphragm and the diaphragm. Background technique [0002] Silicone rubber is composed of silicon-oxygen bonds, which has the characteristics of high bond energy, long bond length, high chemical stability, and good temperature resistance and molding performance. The silicone rubber diaphragm is formed by cross-linking liquid silicone after injection molding or molding. The silicone rubber diaphragm is a thermosetting material with high temperature resistance, good uniformity of diaphragm thickness and excellent acoustic performance. [0003] However, the damping performance of the existing silicone rubber diaphragm is poor, the effect of absorbing noise is poor, and it cannot meet the user's requirements for high damping and high listening performance of sound-producing products. Contents of the invention [0004] A...
