Alternatively, further in one embodiment, a conductive sheet 34 is fixedly disposed on the outer bobbin 31, and alternatively, the conductive sheet 34 is a tin foil, and the tin foil is welded to the outer bobbin 31. The coil 33 is electrically connected to the conductive sheet 34, and circuit leads 91 are provided on the damper 9, the conductive sheet 34 is electrically connected to the circuit leads 91, and the circuit leads 91 are configured to be electrically connected to external devices. In the existing speaker products, when the damper or the cone assembly is combined with the voice coil, lead wires are all connected from the voice coil bobbin or the cone assembly, but when the lead wires cannot be connected from these two positions, there is no suitable method to solve this problem. According to the present disclosure, the problem of the wire leading is easily solved by disposing the conductive sheet 34 on the outer bobbin 31 of the voice coil 3 and arranging the circuit leads 91 on the damper 9, and electrically connecting the conductive sheet 34 and the circuit leads 91.

In one embodiment, the circuit leads 91 are coated on a surface of the damper 9 in a form of braided metal wires. Specifically, the circuit leads 91 are provided on the surface of the damper 9 by braiding silver flat wires in a cloth braiding manner, and are integrally formed with the damper 9 by hot press molding. Alternatively, the circuit leads 91 are braided using seven strands of silver flat wires with a width of 2 mm, and the silver flat wires can be braided to the interior of the damper 9.
