Abstract

PURPOSE:To enable compactness and to increase the efficiency of buzzer sound, by the constitution that the piezoelectric element is fixed to the main body of the oscillation film fixed to the inside of the cover and in contact with the output terminals extended from the main body with elasticity. CONSTITUTION:In the movement 1, the power supply cell and the circuit for buzzer drive are contained, and at the back cover 4, the sound oscillation film 6 consisting of the circular conductor bonded with the piezoelectric or electrostriction element 5 is contacted with the step 4b at its external circumference, and the output terminals 2, 3 of the buzzer drive circuit is contacted with the oscillation film 6 and the element 5 with elasticity to constitute a part of the circuit for buzzer drive. Accordingly, the buzzer unit can be made thinner and the sound of frequency suitable and sensitive to the users can be obtained.
