PURPOSE:To miniaturize the outer diameter of a movement by forming a unitary body of a switch spring and a fixing member of a buzzer. CONSTITUTION:A small buzzer 8 is positioned by a guide of a middle 16, and fixed by a buzzer fixing spring part 9 of the switch spring 10. The outer diameter of the switch spring 10 is approximately equal to that of a circuit 15. Therefore the circuit 15 is approximately equal to the outer diameter of the movement. The outer diameter of the movement is not required to be made large in order to fix the small buzzer 8. The one end of a lead of the small buzzer 8 is electrically conducted to the spring part 9, and the switch spring 10 is electrically conducted to a terminal to which a buzzer driving signal of the circuit 15 is outputted. Therefore the signal can be applied to the small buzzer 8 without providing the special lead terminals from the small buzzer 8. |
