Abstract
The present disclosure disclose a diaphragm dome, the diaphragm dome includes a first carbon fiber layer and a second carbon fiber layer which are alternatively arranged by stacking, the first carbon fiber layer and the second carbon fiber layer are respectively a single-layer structure formed by an one-way extended carbon fiber bundle, an extending direction of the carbon fiber bundle of the first carbon fiber layer is perpendicular to an extending direction of the carbon fiber bundle of the second carbon fiber layer, and a thickness difference exists between the first carbon fiber layer and the second carbon fiber layer. In the diaphragm dome provided by the present disclosure, the material has larger specific strength, thus can reduce the thickness of the diaphragm dome, the carbon fiber layers of the diaphragm dome are well adhered, which is not readily layered, and has good water resistance.
