According to the vibrating diaphragm assembly, the stepped hole is formed in the spherical top, and the waterproof breathable film is filled in the stepped hole, so that the problems of water resistance and ventilation are solved, the air pressure of the front cavity and the rear cavity can be balanced, and the sensitivity performance and the stability of an acoustic device are improved. The waterproof and breathable film prepared by the embodiment of the application has proper aperture range and porosity, the waterproof performance grade is greatly improved while the air permeability requirement is met, and the waterproof grade of 50 meters can be achieved. Meanwhile, the stepped holes and the waterproof breathable film are reasonably arranged, so that the overall strength of the dome is not obviously attenuated compared with that of a dome structure without holes, namely, the overall strength of the dome with the hole structure is improved, and compared with a traditional method, the structure has stronger stability, and the product quality and the service life are effectively improved. Compared with a vibrating diaphragm structure adopting a microporous membrane with an integral structure, the vibrating diaphragm assembly provided by the embodiment of the application has the advantages that the ventilation area is smaller, and the sound loss is smaller. And the waterproof material is applied to wearing waterproof products, and has stronger waterproof pressure capability.
