Abstract
PURPOSE:To reduce the variation in sound when the wrist watch is put on a wrist, in the wrist watch with an alarm which has a sound generating structure wherein a piezoelectric element is attached to its back, by applying a large compressing force to the back itself beforehand. CONSTITUTION:A piezoelectric element 4 is bonded to the inner surface of the back 3. An insulating material is placed on the top surface of the piezoelectric element 4. A module driving battery 6 is contacted with the insulating material 5, and a spring member 8 is provided between the battery 6 and a module 7. The top end surface of the module 7 is contacted with a panel cover part of a middle 2. Another spring part 9 is directly contacted with the module 7 and the piezoelectric element 4. When the back 3 is mounted, the spring force caused by the deformation of the spring member 8 is applied to the module 7, and it is fixed to the middle 2.
