Abstract

PURPOSE:To prevent absormal sound from being generated by constituting a terminal board comprising a terminal chip of arm from fixing a lead of a voice coil at the midpoint and a base fixing the terminal chip so as to prevent the collision among the voice coil 1, a diaphragm 6 and a damper 2. CONSTITUTION:The terminal board 8 consists of a base 8a, and the terminal chip 8b of arm shape to fix the lead wire 3 at the midpoint between the voice coil 1 and the terminal board 8. A U-form notch 8c is provided to fix the lead wire 3 at the tip of the terminal chip 8b. Since the lead wire 3 is fixed at the midpoint between the voice coil 1 and the terminal board 8 by the terminal chip 8b, even if the voice coil 1 is vibrated at a large vibration, the coil does not collide with the diaphragm 6 and the damper 2 then no abnormal sound is generated. Since the U-form notch to clip the lead wire 3 is provided to the tip of the terminal chip 8b the margin in fixing the lead wire 3 or the fixing itself is adjusted easily.
