Abstract

PURPOSE:To obtain a voice coil for speaker excellent in the heat resistance, by using copolymer of polycarbosilane and siloxane system resin for the coating of a copper wire and the winding fixation of said wire to a coil bobbin. CONSTITUTION:On a coil bobbin 1 with heat resistance, insulated copper wires 2 convered with the copolymer of polycarbosilane and siloxane system resin are wound and fixed with the adhesives 4 of the copolymer polycarbosilane and siloxane system resin (e.g., polymetharosiloxane). On the coil bobbin 1 being not wound with copper wires, reinforce paper 5 made of glass cloth is wound.
