Abstract

PURPOSE: To prevent buzzy sound or the like of lead wires and a diaphragm by projecting upward projections of a tangential shape of the diaphragm to fix the diaphragm and the lead wire of a voice coil sufficiently strongly with an adhesive or the like.
CONSTITUTION: A damping cloth 12 and a terminal strip 13 are adhered to the lower face in the outside peripheral part of a yoke 11 which consists of a magnetic material and has a recessed part in the center. A columnar magnet 14 and a discoid plate 15 are adhered to the inside of the yoke 11. A baffle plate 16 is provided with plural sound emission holes in the center part and is coupled to the outside peripheral part of the yoke 11. A diaphragm 17 is adhered to the coupling part between the yoke 11 and the baffle plate 16, and a voice coil 18 is adhered to the diaphragm 17. The diaphragm 17 has a tangential shape shown in the figure, and projections 17a of the tangential part are projected upward, and a lead wire 18a in the front end of the coil 18 is fixed to the lower face of the diaphragm 17 by silicone grease or an adhesive 9.
