ABSTRACT:
A sound signal wire that has higher rigidity to prevent roping effect from reducing sound quality during vibration within a speaker frame, and/or also has a higher flexibility and tensile strength to make the vibrated sound signal wire more durable for use with a speaker for transmitting sound signals is disclosed. The sound signal wire is constructed from sets of weaving wire units which weave onto other sets of support wire units along specific paths, with acetal resin or polyurethane coating the surface of the wire. Each wire unit is comprised of an inner fiber and a conductive metal sheet encompassing the inner fiber, in which the inner fiber is a heat-resistant fiber that is made by a poly meta-aramid fiber mixed-woven with a poly para-aramid fiber.
