Abstract
The utility model provides a there is skeleton voice coil loudspeaker voice coil, including skeleton and coil, the coil adopts two enameled wires to be in with the winding of the shunt wound mode of double -line on the skeleton, the enameled wire includes first enameled wire and second enameled wire, the first end of first enameled wire and second end with the first end and the second end relief of second enameled wire become four lead -out wires for the welding is in external circuit. The utility model discloses a shunt wound mode of double -line, two adopt different wire rods, when the enameled wire in collinear footpath is not parallelly connected, possible and the single resistance that the enameled wire is the same, and under the resistance and the book width of cloth homogeneous phase circumstances together, the shunt wound coil of double -line has lightened 40% weight than single line wound coil, difficult fracture when the parallelly connected welding of double -line has improved the yields in the production process.
Description
Technical field
The utility model belongs to electroacoustic techniques field, and being specifically related to a kind ofly has skeleton voice coil loudspeaker voice coil for earphone or Mobile phone horn.
Background technology
At present, the method reducing voice coil loudspeaker voice coil weight reduces the weight of coil, or reduce the weight of skeleton.But for specific voice coil loudspeaker voice coil specification, when keeping identical resistance and winding, the coil be coiled into by solid wire can not reach the requirement reducing weight and external diameter.
Utility model content
In view of this, the purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can reduce coil weight and external diameter have skeleton voice coil loudspeaker voice coil.
For realizing above object, the utility model adopts following technical scheme: one has skeleton voice coil loudspeaker voice coil, comprises skeleton and coil, and described coil adopts two enamelled wires to be wrapped on described skeleton in the mode of Double-wire parallel wound; Described enamelled wire comprises the first enamelled wire and the second enamelled wire, and the first end of the first end of described first enamelled wire and the second end and described second enamelled wire and the second end form four lead-out wires, for being welded in external circuit.
Described first enamelled wire adopts the one in copper cash, copper-clad aluminum conductor, high-tension copper-clad aluminum conductor, extra-high tension copper-clad aluminum conductor, high-tension line and extra-high tension line.
Described second enamelled wire adopts the one in copper cash, copper-clad aluminum conductor, high-tension copper-clad aluminum conductor, extra-high tension copper-clad aluminum conductor, high-tension line and extra-high tension line.
Described enamelled wire can adopt parallel way to weld, and the first end of described first enamelled wire welds with the first end of described second enamelled wire, and the second end of described first enamelled wire welds with the second end of described second enamelled wire.
Described enamelled wire can also adopt series system to weld, and the second end of described first enamelled wire welds with the first end of described second enamelled wire.
The utility model adopts above technical scheme, when adopting the enamelled wire of different wire rod, different wire diameter in parallel, can accomplish the resistance the same with single enamelled wire for two; And when resistance and winding are all identical, the coil of Double-wire parallel wound alleviates the weight of 40% than the coil that solid wire is coiled into.The utility model is not easy fracture when two-wire parallel connection welding, improves the yields in production process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, skeleton; 2, coil; 3, the first end of the first enamelled wire; 4, the second end of the first enamelled wire; 5, the first end of the second enamelled wire; 6, the second end of the second enamelled wire.
Embodiment
As shown in Figure 1, the utility model provides one skeleton voice coil loudspeaker voice coil, comprises skeleton 1 and coil 2, and described coil 2 adopts two enamelled wires to be wrapped on described skeleton 1 in the mode of Double-wire parallel wound; Described enamelled wire comprises the first enamelled wire and the second enamelled wire, and first end 5 and second end 6 of the first end of described first enamelled wire 3 and the second end 4 and described second enamelled wire form four lead-out wires, for being welded in external circuit.
Described first enamelled wire adopts the one in copper cash, copper-clad aluminum conductor, high-tension copper-clad aluminum conductor, extra-high tension copper-clad aluminum conductor, high-tension line and extra-high tension line.
Described second enamelled wire adopts the one in copper cash, copper-clad aluminum conductor, high-tension copper-clad aluminum conductor, extra-high tension copper-clad aluminum conductor, high-tension line and extra-high tension line.
Described first and second enamelled wires can adopt parallel way to weld, and the first end 3 of described first enamelled wire welds with the first end 5 of described second enamelled wire, and the second end 4 of described first enamelled wire welds with the second end 6 of described second enamelled wire.
When two enamelled wires are in parallel, when the sectional area sum of two-wire is identical with the sectional area of solid wire, the surface area sum of two-wire is larger than solid wire, and the effective resistance of two-wire to upper frequency alternating current is less, can improve the sensitivity of voice coil loudspeaker voice coil.When keeping identical resistance, the sectional area sum of two-wire is less than the sectional area of solid wire, and therefore the coil weight of Double-wire parallel wound is lighter.Keep resistance, winding homogeneous phase simultaneously, the coil that the external diameter of the coil of Double-wire parallel wound and weight are all coiled into than solid wire is little; And the external diameter of coil reduces, magnetic gap can be reduced, increase power output.
Described first and second enamelled wires can also adopt series system to weld, and the second end 4 of described first enamelled wire welds with the first end 5 of described second enamelled wire.The coil winding that the coil winding of, Double-wire parallel wound identical with the resistance of solid wire in the first and second enamelled wire parallel resistances and solid wire are coiled into is also identical, by two enamelled wire series connection welding, now the external diameter of the coil of Double-wire parallel wound and weight less, the coil resistance of Double-wire parallel wound is greater than the coil resistance that solid wire is coiled into, and thus decreases the distortion of loud speaker.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection range of the present utility model.
