PURPOSE:To secure the press-in structure of the case and terminal and to improve the productivity as to the piezoelectric sounder which is used for the annunciation sound of electronic equipment. CONSTITUTION:A piezoelectric diaphragm 14 is mounted in the case 14, the terminal which has a projection part 17a on one surface and a couple of projection parts 17b on the other surface side is pressed and held in the terminal insertion hole 13 of the case 11, and the terminal 17 is connected to the piezoelectric diaphragm 14. The elastic effect that the terminal 17 having the projection part 17a and the couple of projection parts 17b exerts prevents play between the case 11 and the pressed-in part of the terminal 17, the chipping and cracking of the case 11 and the deformation of the terminal 17 can be prevented. |
