Preparation method for horn vibrating reeds

Abstract

The invention provides a preparation method for horn vibrating reeds. The method comprises a step of mixing resin with elastic rubber material, wherein the resin and elastic rubber material are fully mixed and dispersed to form resin and rubber-material mixed slurry; an impregnation step, in which fabrics are impregnated with the resin and rubber-material mixed slurry so that the fabrics absorb the slurry; a baking step, wherein the fabrics absorbing the resin and elastic rubber material are dried via baking; a press-printing and shaping step, wherein the fabrics absorbing the resin and elastic rubber material are shaped into required shapes via hot press printing; and a shaping and cutting step, in which different vibrating reeds are separated from the fabrics after press printing. The fabrics absorb the resin and elastic rubber material via impregnation for once or for multiple times, and the horn vibrating reeds are softened via elasticity of the elastic rubber material, thereby improving ductility and anti-fatigue performance, reducing noises as well as fracturing, deformation and aging phenomena, and prolonging service life.

Description

technical field [0001] The invention relates to a method for manufacturing a horn vibrating piece, in particular to forming the horn vibrating piece with fabrics of absorbent resin and elastic glue. Background technique [0002] refer to figure 1 , figure 1 It is a side view of the internal structure of the horn in the prior art. Such as figure 1 As shown, the speaker internal structure 1 includes a housing 10 , a magnetic core 20 , a voice coil 30 and a speaker vibrating piece 40 (eg, elastic wave). The magnetic core 20 is arranged in the housing 10, the outer surface of the voice coil 30 is wound with a coil to connect to an external power source, and is connected to the magnetic core 20. When the current passes through, electromagnetic induction is generated to vibrate up and down. The speaker vibrating piece 40 is connected to the housing 10, and There is a central through hole 45 for connecting the voice coil 30 . The horn vibrating plate 40 must be light in weight,...

Problems solved by technology

[0004] However, the horn vibrating piece of the prior art only uses resin as a solid body to provide the hardness of the fabric, but when the horn vibrating piece is in use, the resin may be hardened and aged due to factors such as vibration, fatigue stress, heat, etc. The more serious problem is that because the material of the resin is different from the fabric, it is easy to generate noise that resonates with the vibration frequency of the fabric, which will directly affect the sound quality of the speaker, and then affect the value of the speaker. At the same time, it may be damaged, deformed, and cause peeling phenomenon, therefore, there is a need for a solution that can reduce the problem caused by resin hardening
