Abstract

The invention discloses carbon fiber paper. The carbon fiber paper comprises the following effective components in parts by weight: 40-50 parts of long-fiber paulownia pulp, 20-30 parts of short-fiberAyous wood pulp, 2-8 parts of sisal fibers, 5-12 parts of carbon fibers, 1-3 parts of kapok, 1-3 parts of Manila hemp, 1-2 parts of urea resin, and 8-12 parts of wool. The carbon fiber paper is prepared from the raw materials, and the prepared carbon fiber paper is used for preparing a loudspeaker vibrating diaphragm. The problems of layering and overweight of a paper vibrating diaphragm can be effectively solved, and the carbon fiber paper has the characteristics that the Young modulus reaches up to 4G and the sound propagation speed is twice that of a traditional paper vibrating diaphragm.

Description

technical field [0001] The invention relates to a carbon fiber paper, in particular to a carbon fiber paper, and a method for manufacturing the carbon fiber paper, and the prepared carbon fiber paper is used to make a vibrating membrane of a loudspeaker. Background technique [0002] As a common electro-acoustic transducer device that converts electrical energy into sound energy, the speaker plays an indispensable role in the sound reproduction system. The loudspeaker is the weakest component in the sound amplifier system, and it is the most important component for the sound amplifier effect. There are many kinds of loudspeakers, and the audio electric energy makes its paper cone or diaphragm vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. [0003] However, the vibrating diaphragms used for loudspeakers in the market are all made of packaging cardboard or traditional pulp. The produc...
