Claims

[Scope of Claim for Utility Model Registration] 1. A thin plate made of a single material such as metal, plastic, paper, etc. or an appropriate composite material is formed into a cylindrical shape, and a coil is wound around the outer circumference of the cylinder. On the other hand, after stretching both the starting end and the terminal end of the coil along the cylindrical body, both are folded back at appropriate lengths, and the overlapping parts are twisted to form a reinforced structure to form a lead wire. , a voice coil formed by fixing a lead wire of the reinforced structure at a proper position to the surface of the cylinder body. 2. The voice coil according to claim 1, wherein a lead wire having a reinforced structure is fixed to the cylindrical body at a proper position using kraft paper or other reinforcing paper. 3. The voice coil according to claim 1, wherein a lead wire having a reinforced structure is welded and fixed to a conductive plate at a proper position with respect to the cylindrical body.
