Abstract
A voice coil wire, a voice coil wound by the voice coil wire, and a loudspeaker provided with the voice coil, which relate to the technical field of electro acoustic products. The voice coil wire comprises a conductor layer having an electric conduction effect and an insulation layer surrounding an outer side of the conductor layer. The cross-section of the voice coil wire is a hexagon, and the side lengths of the hexagon are equal. The voice coil wire, the voice coil wound by the voice coil wire, and the loudspeaker provided with the voice coil of the application can solve the technical problems in the prior art such as a low volume ratio of the voice coil and a complicated winding process. According to the voice coil wire, the voice coil, and the loudspeaker provided with the voice coil of the application, the voice coil is high in volume ratio, small in volume, good in heat dissipation performance and its winding process is simple, and the loudspeaker is high in sensitivity, small in thickness and good in acoustic performance.
