Graphene cone formula and production process

Abstract

The invention relates to the technical field of electrical sound, and discloses a graphene cone formula and a production process, the graphene cone formula comprises the following raw materials by weight: 30-40% of paper pulp board (EKB), 50-58% of paper pulp board (Beimu), 2-5% of kapok fiber, 8-12% of direct black-red light 3BG dye, 8-10% of aluminum sulfate, 8-12% of industrial salt, 0.2-1% of graphene, 40-50% of polypropylene raw material, 1-1.5% of lubricant, 4.5-3% of maleic anhydride, and 1-0.5% of white oil. According to the graphene paper cone formula and the production process, graphene is added in the manufacturing process of a loudspeaker paper cone, graphite paper composed of graphene sheets has many holes, so that the graphite paper is very brittle, however, functionalized graphene is obtained through oxidation, and then the graphite paper made of the functionalized graphene is very firm and tough, graphene has good toughness and good strength, the rigidity of the cone can be integrally improved without increasing the weight when the graphene is applied to the loudspeaker cone production process, and the purposes of obviously improving the low-medium-high frequency tone quality, increasing the power and improving the sound pressure are achieved.

Description

technical field [0001] The invention relates to the technical field of electroacoustics, in particular to a graphene paper cone formula and production process. Background technique [0002] The paper cone is an important core material of the speaker and has an irreplaceable position. The key point of the design of a satisfactory speaker is the paper cone. The paper cone is the soul of the whole speaker; the frequency response characteristics of the speaker depend on the paper cone. performance, and the performance of the paper cone depends on the material, geometry and processing technology of the paper cone; the following requirements are often put forward for the paper cone material in the production of paper cones: 1. The material density should be small, the quality should be small, and the high-frequency characteristics of the speaker The better the quality, the better the transient characteristics; 2. The Young's modulus E of the material should be large and rigid, whi...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a graphene paper cone formula and production process, which has the advantages of enhancing the rigidity of the paper cone without increasing the weight and enhancing the sound clarity, and solves the problem of insufficient rigidity. The method is to add glass fiber, carbon brazing fiber and other materials, but glass fiber, carbon brazing fiber and other materials have a certain weight, and will lose a certain sound pressure level.
