Problems solved by technology

In the prior art, there are many kinds of diaphragm materials, including paper diaphragm materials, metal diaphragm materials (such as titanium, aluminum-magnesium alloy, etc.), polymer diaphragm materials (such as polypropylene, polyethylene, liquid crystal polymer, etc. ), inorganic non-metallic diaphragm materials (such as ceramics, diamond, boron carbide, etc.), etc., but the single-layer diaphragm made of the above materials has low strength and cannot meet the working needs of the speaker, so the diaphragm is usually made of the same material o

Abstract

The invention discloses a loudspeaker diaphragm preparation method, comprising: employing a high-molecular polymer as a base material; doping the base material with graphene materials through an in situ polymerization method or a solution mixing method to form a grapheme high-molecular polymer mixed material film; and preparing a loudspeaker diaphragm through laser cutting or punching. In the method, the graphene materials are introduced into the high-molecular polymer for mixing to form the grapheme high-molecular polymer mixed material film so as to prepare the loudspeaker diaphragm; because of the mechanical property of the graphene materials, the loudspeaker diaphragm has the characteristics of stronger robustness, shock resistance, abrasion performance and light weight.

Description

technical field [0001] The invention relates to the technical field of loudspeaker diaphragm manufacturing, in particular to a method for preparing a loudspeaker diaphragm. Background technique [0002] Loudspeakers are electroacoustic converters that can convert electrical signals into acoustic signals and radiate them into the air. They are widely used in electronic products. Loudspeakers usually include magnetic circuit systems, vibration systems, and support systems. The loudspeaker vibration system includes a diaphragm and a voice coil combined on one side of the diaphragm. The diaphragm is one of the most important components of the speaker and is mainly used to radiate sound. The selection of the material of the diaphragm has a great influence on the sound quality, tone, Timbre plays a vital role. [0003] The basic requirements for speaker diaphragm materials are: ①The density of the diaphragm material should be as low as possible to ensure that the speaker has high...
