  • Publication number: 20170272865
    Abstract: The present disclosure discloses a voice coil wire, a voice coil manufactured by winding the voice coil wire, a loudspeaker and a vibration motor, and relates to the technical field of electroacoustic products. The voice coil wire comprises a conductor layer having an electric conduction function, the outside of the conductor layer being wrapped by an insulating layer, wherein the conductor layer comprises a first conductor layer disposed inside and a second conductor layer wrapping the outside of the first conductor layer, and one of the first conductor layer and the second conductor layer is made of a soft magnetic material. The voice coil wire, the voice coil manufactured by winding the voice coil wire, the loudspeaker and the vibration motor of the present disclosure solve the technical problem of the prior art that voice coils do not have magnetoconductivity.
