Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the speaker cone with a corrugated rim of composite structure includes a T-iron 1, a magnet 2, an upper clamp plate 3, a voice coil 4, a frame 5, a damper 6, a cone 7, a dust cover 8, a corrugated rim 9, and a blank holder 10, wherein the T-iron 1, the magnet 2, the upper clamp plate 3, the voice coil 4, the frame 5, the cone 7, the damper 6, the dust cover 8, the corrugated rim 9, and the blank holder 10 are all coaxially disposed,

an upper clamping plate 3 is arranged at the top of the T iron 1, a magnet 2 is arranged between the T iron 1 and the upper clamping plate 3, a basin frame 5 is fixed at the top of the upper clamping plate 3, a voice coil 4 is sleeved at the top of the T iron 1, gaps are reserved among the magnet 2, the upper clamping plate 3 and the T iron 1, the lower part of the voice coil 4 is located in the gap, the upper part of the voice coil 4 is located in the basin frame 5, the outer edge of an elastic wave 6 is fixedly bonded at the inner side of the basin frame 5, and the inner ring of the elastic wave 6 is fixedly connected with the outer wall of the voice coil 4; the bottom of the cone 7 is fixedly connected with the top of the voice coil 4, the outer edge of the top of the cone 7 is bonded with the inner ring of the folding ring 9, the outer ring of the folding ring 9 is bonded with the top of the cone frame 5, a blank holder 10 is fixedly arranged on the top of the cone frame 5 and used for pressing the folding ring 9, and a dust cover 8 is fixedly arranged on the top of the voice coil 4;
