[0002] The voice coil and the cone are important components of the speaker sound unit. When current passes through the voice coil, an electromagnetic field is generated. This electromagnetic field interacts with the magnet to drive the cone to vibrate, thereby generating sound. For example, a cone and a speaker having the cone disclosed in patent number CN219999585U have a planar connection structure at the connection between the cone and the voice coil. The planar connection mode results in limited connection strength, limited electrical signal restoration, and easy distortion. Summary of the invention

[0007] In several embodiments, the connector 1 and the connector 2 are both in the shape of a triangle, a square, or a trapezoid.

[0008] In several embodiments, the cone is in one of a planar three-dimensional, curved three-dimensional or conical three-dimensional shape.

[0010] In several embodiments, the cross-section of the voice coil is one of a square and a rectangle.

[0011] In several embodiments, the cross-section of the voice coil is one of a circular shape and an elliptical shape.

[0012] Furthermore, the production method of the above-mentioned special-shaped sound unit comprises the following steps:

[0013] S10: rolling the punched flat material of the connector body 1 with the protrusions on a mold into a voice coil of a specific shape;
