Abstract

PURPOSE:To improve the quality and reduce the production cost, by inserting and molding a lead near an upper yoke through a frame and connecting a terminal to the upper end. CONSTITUTION:An upper yoke 3, a magnet 2, and a lower yoke 4 are assembled and fixed onto a frame 1, and the magnet 2 is magnetized, and a voice coil 6 is mounted, and a voice coil terminal 9 is connected and fixed to a lead, and the coil 6 and a vibration diaphragm 5 are caused to adhere to each other. Next, the diaphragm 5 is welded to the frame 1 by ultrasonic waves. Since a lead 10 to which the terminal 9 is connected faces to the side of the diaphragm 5 and is near the coil 6, the terminal 9 is very short. The other end of the lead 10 is in the side opposite to the diaphragm 5 and is so placed that it can be connected to the circuit. Therefore, the damage of the diaphragm is reduced considerably, and disconnection defects of the terminal are reduced, and automatization is facilitated.
