Abstract
A multi-stranded voice coil wire includes an elastic body and at least a metal wire. The metal wire is twisted around the elastic body, the metal wire being surrounded by an insulating layer, and the insulating layer being surrounded by an adhesive layer. In the present invention, the elastic body and the metal wire of different materials are stranded together, which makes the present voice coil has smaller height as compared to the convention voice coil has the same resistance and the same configuration size. This makes the present voice coil have more strength and longer lifetime, and helps to design a thinner loudspeaker and increases the heat dissipation efficiency of the voice coil.
