In specific implementation, the raised portion 3d is preferably wavy, and the peripheral portion 1b, the central portion 1a and the outer edge end 3a of the first sound film 3 of the diaphragm 1 are located on the same horizontal plane. The inner edge end 3b of the first diaphragm 3 is parallel to the horizontal plane. Of the adjacent ridges, the ridge closer to the inner edge end 3b is located at a greater distance from the horizontal plane than the ridge closer to the outer edge end 3 a. That is, a step is formed between the inner edge end 3b and the outer edge end 3a of the first diaphragm 3, and the height of the wavy bulge portion 3d of the second flange portion 3c (i.e., the distance from the horizontal plane) increases from the outer edge end 3a toward the inner edge end 3 b.
More preferably, the outer peripheral end 2a of the connecting member is connected to the side of the inner end 1ab facing away from the first ring-folding portion 1c, and the inner peripheral end 2b of the connecting member is connected to the side of the outer peripheral end 3a facing away from the second ring-folding portion 3 c. The structure is used for stably connecting the connecting piece 2 with the vibrating diaphragm 1 and the first sound film 3 and is conveniently connected with an internal voice coil assembly.
In the basic solution of this embodiment regarding the diaphragm assembly, the diaphragm 1 is designed into a ring shape as a whole, and the central portion 1a is connected to the first diaphragm 3 through the ring-shaped connecting member 2, so as to form the diaphragm assembly.
