Abstract
A speaker's damper is comprised of a main body and lead wires, in which the damper's main body is essentially a piece of woven cloth pressed in the form of an annular disk with a corrugated cutaway section while the lead wire is a metallic wire in texture properly interwoven in the damper's main body so that the jumping-rope phenomenon of the lead wire can be avoided when the damper's main body is in vibration. The lead wire is securely attached to the main body on the woven cloth and beneath a plurality of lifted-up cloth segments. Also, by means of a guide sleeve, two lead wires can be prevented from being short-circuited during vibration of the dampers main body.
