Embodiment
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment
Shown in composition graphs 1 and Fig. 2, a kind of dynamic iron unit with Graphene pcb board of the present embodiment, the pcb board 3 comprising shell 1, be located at vibrating diaphragm in shell 1 and driven unit 2 and be located on shell 1 outer surface, driven unit 2 connects vibrating diaphragm by conductive bar, after energising, driven unit 2 drives vibrating diaphragm to produce dither, and vibrating diaphragm agitates the air in shell 1 to sound.Extraneous wire bonds is on pcb board 3, and as shown in Figure 1, the position of this solder joint is different from the bond pad locations of the winding wire in driven unit 2 and pcb board 3, therefore winding wire can not be made to rupture when welding; In addition, as shown in Figure 3, extraneous wire and Inside coil wire identical with pcb board 3 weld locations, directly utilize the thickness of pcb board 3 also can play the problem preventing winding wire from rupturing, and this mode can shorten conducting wire 31 length in pcb board 3; Extraneous wire is connected with the winding wire in driven unit 2 by pcb board 3, thus driven unit 2 is worked, with existing pcb board unlike, conducting wire 31 on pcb board 3 in the present embodiment is made up of graphene conductive material, not only solve the problem of dynamic iron unit wire fracture when erecting and welding, and reduce the impact of original pcb board on dynamic iron unit tonequality.
