Abstract
(EN)
A sound producing device comprises: a magnetic circuit system (19) configured to form a magnetic field; and a vibration system comprising a voice coil (16), a diaphragm (11), and a reinforcement layer (15). One end of the voice coil (16) is connected to a center portion of the diaphragm (11), and the other end is located in a magnetic field. The reinforcement layer (15) is disposed in the center portion, and comprises a carbon fiber prepreg layer (26). The diameter of carbon fibers in the carbon fiber prepreg layer (26) is less than or equal to 7 μm. The carbon fibers located in the same layer are unidirectional and disposed side by side.

La présente invention concerne un dispositif de production de son comprenant : un système de circuit magnétique (19) conçu pour former un champ magnétique ; et un système de vibration comprenant une bobine acoustique (16), un diaphragme (11), et une couche de renforcement (15). Une extrémité de la bobine acoustique (16) est reliée à une partie centrale de la membrane (11), et l'autre extrémité est située dans un champ magnétique. La couche de renforcement (15) est disposée dans la partie centrale, et comprend une couche préimprégnée en fibres de carbone (26). Le diamètre des fibres de carbone dans la couche préimprégnée de fibres de carbone (26) est inférieur ou égal à 7 µm. Les fibres de carbone situées dans la même couche sont unidirectionnelles et disposées côte à côte.
