Background

In the prior art, an insulating sheet material, a metal sheet material or a mixture sheet material is often adopted in a sound tube and rolled into a tubular shape with a set diameter to be used as a framework of a voice coil. One end of the voice tube is uniformly wound with an enameled copper wire to form a coil, and after the coil is wound to a specified number of turns, the two ends of the coil are led out and are wound and fixed by an insulating material to complete the manufacture of the voice coil.

The defects of the existing voice coil;

1. the material is formed by stacking a plurality of materials, and the temperature resistance of the materials is insufficient and is not more than 250 ℃ due to different temperature resistances. The firmness of the pasting is unstable, the hardness of the voice coil is unstable, and poor line scattering/line falling is easy to occur;

2. the framework and the copper wire are separated and are attached by glue, so that the weight of the glue is increased;

3. the thickness of the insulating layer of the enameled wire, the gap between the enameled wires, the thickness of glue and the superposition of various thicknesses make the enameled wire difficult to be made thin;
