Embodiment

[0012] The invention relates to a carbon fiber cloth and paper pulp direct papermaking composite basin, which is formed after the carbon fiber woven cloth is impregnated with resin, and then placed on a papermaking mold, pressed and dried together with the papermaking wet pulp to form a composite paper basin. The weight ratio of the carbon fiber woven cloth to the pulp is 1:1.

[0013] The invention is a composite basin made of carbon fiber and paper pulp. The pulp is infiltrated into carbon fiber cloth and interwoven together without glue bonding. It has better firmness, has both the rigidity of carbon fiber and the damping of paper fiber, and can be adjusted at the same time. Pulp ratio, less distortion, more realistic sound reproduction.

Abstract

The invention relates to a paper cone in a loudspeaker. A carbon fiber cloth and paper pulp direct papermaking composite cone is formed by impregnating a carbon fiber woven fabric with resin; then placing the carbon fiber woven fabric on a papermaking mold, and drying the carbon fiber woven fabric together with the papermaking wet paper pulp to form a composite paper cone. Further, the weight ratio of the carbon fiber woven fabric to the paper pulp is 1:1 to 1:1.5. The invention relates to a composite cone composed of carbon fibers and paper pulp. The paper pulp penetrates into the carbon fiber cloth and interweaves with the carbon fiber cloth. Thus, glue bonding is not required and good firmness is achieved. The paper cone has both the rigidity of the carbon fibers and the damping of paper fibers. The paper pulp ratio can be adjusted to achieve an effect with less distortion and realistic reproduction of various sounds.

Description

technical field [0001] The invention relates to paper cones in loudspeakers. Background technique [0002] In the loudspeaker, the voice coil will vibrate strongly in the magnetic field after the audio signal is connected. The voice coil is fixed on the paper cone, and the vibration of the voice coil drives the vibration of the paper cone at the same time. sound. In order to achieve a good pronunciation effect, the paper cone is generally made into a cone shape, and the paper cone of some woofers is made into a flat type, called a flat panel speaker. [0003] Ordinary speaker cones are made of ordinary paper. With the continuous advancement of science and technology, people's requirements for audio quality continue to improve, and various sound cones have appeared one after another. It is no longer a material for paper cones, such as wool. Basin, metal basin. The different materials of the cones lead to differences in sound quality. At present, the speaker cones on the m...
