Abstract

PURPOSE:To output the alarm sound from the front of the watch case simply, by the sound path of insertion gap between the inner and outer shells. CONSTITUTION:The vibration plate 7 providing the piezoelectric element 13 at the inside bottom surface is located to cover the lower opening of the inner shell 5, the external circumference is depressed with the step 8a at the bottom of the external shell 8, and the inner shell 5 and the outer shell 8 are coupled with the plate spring 14 by forming the insertion gap 15. Thus, the alarm tone by the vibration of the vibration plate 7 is fed to the insertion gap 15 from the space 16 between the vibration plate 7 and the external shell 8 to output sound from the front of watch. Accordingly, without increasing the manufacture cost such that the sound path is machined on the shells, the alarm tone can be outputted from the front of watch.
