In each of the speaker dampers disclosed in Japanese Patent Publication No. 100 and Japanese Patent Laid-Open Publication No. 4-144500, a band-shaped conductive member having a predetermined width, which is a braided braided wire, is sewn to the damper body with fibers. That is, a conductive member formed by braiding a tinsel wire along the shape of the molded corrugation on the front or back surface of a damper material having corrugation on a cloth material such as woven fabric or nonwoven fabric is simply used for industrial use. Using a sewing machine, fibers (threads) are sewn from the inner periphery to the outer periphery.

上解決すべき多くの課題を有している。[0004] As the conductive member formed by braiding the tinsel wire, a member having a thickness of about 0.6 mm and a width of about 3 mm is often used, but when sewing to a damper material, the damper material is used. Since the conductive member is positioned to some extent and placed on it and sewn with a sewing thread from above, it is not easy to attach the conductive member to the damper material, and the weight of the conductive member may change the speaker performance. In addition, since the conductive member needs to be braided in a braided wire shape, it has many problems to be solved in practice, such as affecting the manufacturing cost of the speaker.
