Abstract

The invention relates to the technical field of electroacoustic devices, in particular to a carbon fiber dome and a loudspeaker. The carbon fiber dome comprises a first carbon fiber layer, a base material layer and a plurality of second carbon fiber layers which are sequentially stacked, the first carbon fiber layer comprises an upper surface and a lower surface which are opposite to each other, the base material layer is arranged on the upper surface of the first carbon fiber layer, and the upper surface comprises a hollow first area and a second area surrounding the first area. And the second area comprises at least two layers of carbon fiber unidirectional belt prepregs. According to the carbon fiber dome and the loudspeaker, the number of the stacking layers of the middle local area ofthe carbon fiber dome is smaller than that of the stacking layers of the peripheral areas, so that the thickness of the carbon fiber dome is reduced, the mass of the carbon fiber dome is reduced, andthe high-frequency performance of a product is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of electroacoustic devices, in particular to a carbon fiber dome and a loudspeaker. 【Background technique】 [0002] The dome-shaped speaker refers to a speaker that uses a dome-shaped diaphragm to directly radiate sound waves. It belongs to an electric speaker. The diaphragm is a hemispherical diaphragm, and the voice coil is directly supported by the diaphragm ring without a centering piece. It is characterized by Good high-frequency response, wide directivity and low distortion. [0003] The carbon fiber dome in the prior art is generally stacked by multiple layers of carbon fiber materials, and the stack is completely uniform, but the product has poor high-frequency frequency response and poor sound quality. [0004] Therefore, it is necessary to provide a new technical solution to solve the above technical problems. 【Content of invention】 [0005] The purpose of the present invention is to provide ...
