PURPOSE:To prevent a copper foil film from touching surroundings during operation and to prevent breaking of wire in terms of service life by sticking firmly a copper foil film that connects the wire of a voice coil and a terminal attached to a frame on a damper. CONSTITUTION:The copper film 10 is stuck firmly on the damper 6 with a flexible silicone adhesive etc. The copper foil film 10 is made by laying copper foil 12 in a film 11. As a copper foil film 10 is used in place of a copper foil thread wire 2 and stuck firmly on the damper 6 with a flexible substance, abnormal sound generated by touching of the copper foil film 10 as a junction line from the wire of the voice coil 1 to a terminal 9 on surrounding parts due to vibration and amplitude at the time of operation of the loudspeaker can be prevented. At the same time, disconnection caused by service life due to length of the copper foil film and defective forming can be prevented. |
