Abstract: A vibrating diaphragm assembly related to the technical field of electroacoustic products is provided. The vibrating diaphragm assembly comprises a vibrating diaphragm, wherein the vibrating diaphragm comprises a middle part and a folding ring part surrounding the periphery of the middle part. The vibrating diaphragm also comprises a vibrating diaphragm substrate layer and a silica gel layer; the silica gel layer being at least partially combined with the vibrating diaphragm substrate layer. The vibrating diaphragm substrate layer is also a high molecular material layer; the silica gel layer is combined on the surface of the folding ring part; and the silica gel layer and the high molecular material layer are formed through injection molding.

Abstract: Disclosed is a vibrating diaphragm assembly, which relates to the technical field of electroacoustic products. The vibrating diaphragm assembly comprises a vibrating diaphragm, wherein the vibrating diaphragm comprises a middle part and a folding ring part surrounding the periphery of the middle part; the vibrating diaphragm comprises a vibrating diaphragm substrate layer and a silica gel layer; the silica gel layer is at least partially combined with the vibrating diaphragm substrate layer; the vibrating diaphragm substrate layer is a high molecular material layer; the silica gel layer is combined on the surface of the folding ring part; and the silica gel layer and the high molecular material layer are formed through injection molding. The vibrating diaphragm assembly of the present invention can improve the compliance of a vibrating diaphragm by arranging a silica gel layer on the surface of a folding ring part and compounding the silica gel layer and a high molecular material layer, improve the chemical stability and the temperature adaptability thereof, optimize the acoustic performance, and improve the product qualification rate.
