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.

Abstract: A loudspeaker module comprises an outer casing in which a vibration system and a magnetic circuit system are received. The magnetic circuit system comprises a basin-like stand fixed on the outer casing. The outer casing comprises a second casing provided with a rear sound exit hole that transversely runs through the inner side surface and the outer side surface of the second casing at the position corresponding to the outer side surface of the sidewall of the basin-like stand. The rear sound exit hole is communicated with an inner cavity of the module and an inner cavity of the electronic terminal. A chamfered plane is disposed at an upper end of the sidewall of the basin-like stand, and on a side of the sidewall of the basin-like stand. A sound emitting channel is formed between the chamfered plane and the inner side surface of the second casing.
