2. Description of the Related Art The principle of operation of a dynamic speaker is well known. By the way, there are two methods of supplying power to the voice coil of the dynamic speaker, a method of supplying power through a tinsel wire, and a method of providing a conductive portion in a damper.

The former is shown in FIG. 2, and the latter is shown in FIG. As shown in FIG. 2, the signal input wiring structure of the conventional speaker unit is such that a terminal plate 16 is attached to a frame 13, a tinsel wire 15 is guided from the terminal plate 16 to a cone diaphragm 14, and the surface of the cone diaphragm 14 is crawled. For example, the voice coil 12 is connected to the voice coil 12 or, as shown in FIG.
2 and 3, reference numeral 17 denotes a magnetic circuit unit.

In the speaker shown in FIG.
Is the bobbin 1 of the voice coil 12 as shown in FIG.
The inner ring portion 2 to be connected to the inner ring portion 2a and the outer ring portion 3 to be attached to the frame 13 are connected by a connecting portion 4,
The conductive pattern 5 is printed from the inner peripheral edge 2a to the outer peripheral portion 3a of the outer ring portion 3 via the connecting portion 4.
This print is obtained by insert-molding or sewing a conductive material into a damper made of resin.

[0005] In the conventional example described above, in the example shown in FIG. 2, the tinsel wire is apt to be cut and often comes into contact with the cone diaphragm or the damper, making it difficult to reduce the thickness. Also,
In the example shown in FIG. 3, since the conductive pattern is obtained by insert-molding or sewing a conductive material into a resin-molded damper, the manufacturing cost is high and the strength of the joint is increased. It was difficult.

The present invention has been made in view of the above circumstances, and uses a damper itself as a conductive material by sticking, coating, and mixing a conductive material on a resin, and punching or molding the same into at least two or more. Accordingly, it is an object of the present invention to provide a speaker damper which achieves a thinner and higher-powered speaker, achieves stable strength and lower cost, a method of manufacturing the same, and a speaker device including the damper.

In order to solve the above-mentioned problems, the invention according to claim 1 includes at least two conductive damper members separated from each other. This eliminates the need to use a tinsel wire by using the damper itself as a conductive material, thereby realizing a thin and high-power speaker.

According to a second aspect of the present invention, there is provided a voice coil for vibrating a diaphragm, and at least two separated conductive coils for connecting the diaphragm to a frame and supplying an input signal to the voice coil. And a speaker damper made of a damper member. This simplifies the signal input wiring structure of the speaker unit, facilitates input to the voice coil, improves workability, and facilitates speaker assembly.

According to a third aspect of the present invention, in the speaker damper or speaker device according to the first or second aspect, the conductive damper member is made of a resin member and a conductive material bonded to the resin member. And According to a fourth aspect of the present invention, in the speaker damper or speaker device according to the first or second aspect, the conductive damper member includes a resin member and a conductive material applied to the resin member. did. According to a fifth aspect of the present invention, in the speaker damper or speaker device according to the first or second aspect, the conductive damper member is made of a resin member and a conductive material mixed in the resin member. did. As a result, the damper itself can be used as a conductive material, and the need for a tinsel wire can be eliminated, so that the speaker can be made thinner and higher in power. In addition, since there is no need to insert or sew the conductive material, the strength can be reduced. Stability and cost reduction.

According to a sixth aspect of the present invention, there is provided a speaker damper including at least two conductive damper members separated from each other, wherein the conductive damper member is formed by bonding a resin member and a conductive material to the resin member. The method includes a step of forming, and a step of punching or molding the formed conductive damper member separately into at least two parts. The invention according to claim 7 is a speaker damper including at least two conductive damper members separated from each other, wherein a resin member and a conductive material are applied to the resin member to form a conductive damper member. And a step of punching or molding the formed conductive damper member separately into at least two parts. An invention according to claim 8 is a speaker damper including at least two conductive damper members separated from each other, wherein a resin member and a conductive material are mixed with the resin member to form a conductive damper member. And a step of punching or molding the formed conductive damper members separately into at least two parts. According to each of the above manufacturing methods, since the damper itself is used as the conductive material and the tinsel wire is not used, the speaker can be made thin and high power can be realized. Stabilization of strength and cost reduction are achieved because they are not required.
