DETAILED DESCRIPTION

[0033] The present disclosure will be further illustrated with reference to the figures and the embodiments.

Embodiment 1

[0034] As shown in FIG. 1, a voice coil wire, comprising a conductor layer having an electric conduction function, and the outside of the conductor layer being wrapped by an insulating layer 30, and the outside of the insulating layer 30 is wrapped by a self-adhesive layer 40, wherein the conductor layer comprises a first conductor layer 10 disposed inside, and a second conductor layer 20 wrapping the outside of the first conductor layer 10.

[0035] As shown in FIG. 1, the first conductor layer 10 is made of a soft magnetic material. The soft magnetic material in the present embodiment is one of pure iron, low-carbon steel, iron-silicon alloys, iron-nickel alloys, iron-silicon-aluminum alloys, iron-aluminum alloys or iron-cobalt alloys, but not limited to the above materials. A metal is feasible so long as it has a high magnetoconductivity and an electrically conductive performance. The second conductor layer 20 is made of copper. The present disclosure adds a conductor layer made of a soft magnetic material into the voice coil wire, so that the voice coil wire adds the magnetic conduction function, such that the voice coil manufactured by winding the voice coil wire has a magnetic conduction function, which increases the Lorentz force received by the voice coil in the magnetic field, and thereby boosts the performance of products provided with the voice coil, such as a loudspeaker, a vibration motor or the like.

Embodiment 2

[0036] As shown in FIG. 1, the present embodiment is substantially the same as Embodiment 1 and differs from Embodiment 1 in that the first conductor layer 10 is made of copper, and the second conductor layer 20 is made of a soft magnetic material.

Embodiment 3

[0037] A voice coil manufacture by winding the voice coil wire, wherein the voice coil wire is the voice coil wire as stated in Embodiment 1 and Embodiment 2.

[0038] The voice coil may allow the magnetic lines of force in the magnetic field to pass through the voice coil to a maximum degree, which effectively increases the magnetic induction intensity, and meanwhile effectively reduces magnetic flux leakage, thereby obtaining the optimal performance.

Embodiment 4

[0039] A loudspeaker, comprising a vibration system and a magnetic circuit system, the vibration system comprising a vibrating diaphragm and a voice coil, which are joint together, wherein the voice coil is the voice coil as stated in Embodiment 3.

[0040] The loudspeaker has advantages such as small size, light weight and good acoustic performance.

Embodiment 5

[0041] A vibration motor, comprising a housing, inside which is fixed a voice coil, and further comprising a magnet and a mass block which are secured together, wherein the magnet and the mass block are suspended in the housing via an elastic support, wherein the magnet and the mass block correspond to the voice coil in a vertical direction, and wherein the voice coil is the voice coil stated in Embodiment 3.

[0042] The present disclosure adds a conductor layer made of a soft magnetic material into the voice coil wire, so that the voice coil wire adds the magnetic conduction function, such that the voice coil manufactured by winding the voice coil wire has a magnetic conduction function, which increases the Lorentz force received by the voice coil in the magnetic field. Technicians carried out simulation experiments for the voice coil of the prior art and the voice coil manufactured by winding the voice coil wire of the present disclosure in terms of their force bearing in the same magnetic field. The experiment results are shown in FIG. 2 and FIG. 3. The Lorentz force received by the voice coil of the prior art is 0.832592N, and the Lorentz force received by the voice coil manufactured by winding the voice coil wire of the present disclosure is 1.016N. It can be seen that in the same magnetic field the voice coil manufactured by winding the voice coil wire of the present disclosure receives a larger Lorentz force, exhibits a better performance and thereby effectively improves the performances of the loudspeaker and the vibration motor and reduces the masses and sizes of the loudspeaker and the vibration motor.

[0043] The present disclosure is not limited to the above specific embodiments. Diverse variations made by those having ordinary skill in the art from the above concept without making any inventive efforts all fall within the protection scope of the present disclosure.
