The tinsel wire 14 arranged on the back side of the cone paper is adhered to the cone paper 2 with an adhesive 16 in order to prevent contact noise from being generated when the cone paper 2 vibrates. Further, a conductive wire 17 extending from the winding start or winding end of the voice coil 4 wound around the coil bobbin 3 is soldered with solder 15 to the tinsel wire arranged on the surface between the holes 2b and 2c. 16 and adhered to the cone paper 2.

[Problems to be Solved by the Invention] In the conventional wiring structure shown in FIGS. 8 and 9, the routing of the tinsel wire 14 is complicated, making the wiring work complicated and inevitably increasing the number of man-hours. automation is extremely difficult. As a result, wiring was done by hand, resulting in inconsistent quality. Further, when the cone paper 2 of the woofer 1 vibrates greatly, the tinsel wire 14 on the upper side of the cone paper 2 may resonate and hit the dustproof damper 12 etc., causing abnormal noise. Appropriate forming must be done. Such forming also makes automation difficult, and there is also a risk that defective products may occur due to poor forming. In addition, cone paper 2
The tinsel wire 14 arranged on the lower side of the paper cone 2 may also come into contact with the back surface of the cone paper 2 or the damper 8, so appropriate forming is required. As described above, the wiring structures shown in FIGS. 8 and 9 have the disadvantage that the quality is not stable and the number of man-hours for wiring increases.

Even in the wiring structure shown in FIG. 10, the wiring work is complicated because the lead wires 18 are routed in a complicated manner, and the wiring is done manually, resulting in unstable quality.

The present invention has been made in view of the above-mentioned points, and its purpose is to provide a speaker wiring structure that provides better productivity and stable quality. be.

Further, the conductive material of the dust-proof damper and the terminal of the mid-high frequency speaker are in contact with each other, and the conductive material of the damper and the speaker terminal are also in contact with each other and can be connected by soldering or crimping. In this way, wiring work becomes extremely simple and automation becomes easy. Furthermore, since there is no conductive material to be routed through the air, there is no possibility of abnormal noise being generated.
