[0002] The direct definition of voice coil is the coil through which electric current passes in the speaker. It is an important component of the mechanical wave system of the electric speaker and can also be said to be the heart of the speaker.

[0003] During the manufacturing process of the voice coil, the wire needs to be wound on an aluminum tape. In order to increase the tightness of the connection between the wire and the aluminum tape ring, glue needs to be applied on the surface of the aluminum tape ring to increase the viscosity. Usually, the glue is applied to the aluminum tape manually first, and then the glue on the aluminum tape ring is evenly applied using a tool. Finally, the aluminum tape ring is rotated to wrap the wire around the aluminum tape. Manual operation requires continuous removal of glue to ensure the amount of glue applied, which is inefficient.
