Abstract

PURPOSE:To enable to separate the sound mechanism from the wrist watch main body and to enable simple connection, by providing the two concentric conducting sections under the sound mechanism and contacting it to the two output terminals extended from the wrist watch main body with elasticity. CONSTITUTION:In the movement 1, the power supply for buzzer and watch drive and the circuit for buzzer drive are contained, and at the back cover 4 being the sound mechanism, the sound oscillation film 6 consisting of circular conductor bonded with the piezoelectric or electrostriction element 5 is in contact with the step 4b at the external circumference, and the output terminals 2, 3 for the buzzer drive circuit are contacted with the oscillation film 6 and the element 5 with elasticity to constitute a part of the circuit for buzzer drive. Accordingly, the sound mechanism 4 can be handled separately from the external package and the watch main body at assembling and disassembling, and since it can be fitted independently of the rotating angle, the handling can be made easy.
