[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure of a speaker, and more particularly, to a wiring structure of a speaker in which a speaker for middle and high sounds is integrally arranged on the front of a speaker for low sound.

[0002]

2. Description of the Related Art FIGS. 8 to 10 show an example of a wiring structure of a speaker in which a mid- and high-frequency speaker (a squawker, a tweeter, etc.) is integrally arranged on the front of a conventionally used low-frequency speaker (woofer). I will explain. FIGS. 8 and 9 show a method in which a tinsel wire 14 is relayed to the cone paper 2 of the woofer 1, and a lead wire for inputting an audio signal is wired to the tweeter 11 by the tinsel wire 14. As shown in FIG. 8, the tweeter 11 is disposed coaxially with the woofer 1 in front of the cone paper 2 of the woofer 1. That is, in the magnetic circuit composed of the magnet 6, the top plate 7 and the yoke 5 of the woofer 1, the support 1 is provided at the center of the yoke 5 in the magnetic circuit.
0 is fixed, and a tweeter 11 is attached to the tip of the column 10. The input terminal 11 a of the tweeter 11 is connected to an input terminal 13 fixed to the frame 9 by a tinsel wire 14.
As is well known, a Kinshi wire has extremely good amplitude resistance.

As shown in detail in FIG. 9, holes 2b and 2c are provided near the neck 2a on the inner periphery of the cone paper 2, holes 2d are provided near the center, and the tinsel wire 14 passes through the hole 2b. It is guided to the front surface, to the back surface through the hole 2c, and further to the front surface through the hole 2d.

[0004] A tinsel wire 14 extending from the surface of the cone paper 2 is soldered to the input terminal 11a by a solder 15.
The tinsel wire 14 extending from the back of the cone paper 2 is connected to the input terminal 13.
Soldered. The tinsel wire 14 arranged on the back surface of the cone paper is adhered to the cone paper 2 with an adhesive 16 in order to prevent a contact sound from being generated when the cone paper 2 vibrates. A lead wire 17 extending the start or end of the winding of the voice coil 4 wound around the coil bobbin 3 is soldered to the tinsel wire disposed on the surface between the holes 2b and 2c by the solder 15, and then the adhesive is applied. 16 covered corn paper 2
Adhered to.

[0005] The inner periphery of the damper 8 is adhered to the coil bobbin 3 and the outer periphery is supported by the frame 9.
The dustproof damper 12 for preventing dust and the like from entering between the voice coil 4 and the magnetic gap has an outer peripheral portion bonded to an intermediate portion of the cone paper 2, and an inner peripheral portion supported by the column 10. These dampers 8 and dustproof dampers 12 are generally provided with corrugations as shown in the drawing so as to follow the vibration of the cone paper 2 well.

Next, an example of the wiring structure shown in FIG. 10 will be described. In this case, the yoke 5 is provided with a hole 5a,
Are provided with holes 10a, lead wires 18 are passed through these holes,
Both ends of the lead wire 18 are soldered to the input terminals 11a and 13. Wiring of the voice coil 3 of the woofer 1 is performed by a tinsel wire 14 similarly to that shown in FIG.

In the conventional wiring structure shown in FIGS. 8 and 9, since the wiring of the tinsel wire 14 is complicated, the wiring work becomes complicated, and the number of man-hours inevitably increases. And extremely difficult to automate. Therefore, the wiring is performed manually and the quality is not stable. 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 or the like to generate an abnormal sound. Appropriate forming must be performed. Such forming also makes automation difficult, and there is a possibility that defective products may be generated due to defective forming. Note that the tinsel wire 14 disposed below the cone paper 2 may also hit the back surface of the cone paper 2 or the damper 8, and thus requires appropriate forming. 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 wiring operations is increased.

[0010] In the wiring structure shown in FIG. 10 as well, the wiring work is complicated due to the complicated arrangement of the lead wires 18, and the wiring is performed manually, and the quality is not stable.

The present invention has been made in view of the above points, and an object of the present invention is to provide a wiring structure of a loudspeaker which can obtain better productivity and has a stable quality. is there.
