Abstract

PURPOSE:To provide an electronic wrist watch with an acoustic device which can attach or detach a cell in hatch type by forming a vibrating plate for generating an alarm sound of a wrist watch in doughnut shape and mounting the plate through a packing at its back cover. CONSTITUTION:A glass plate 2 is formed on the upper surface of a watch case 1 with a display surface. A back cover 3 is fixed by screws 5 to the case 1 on the back side. A hatch 4 for detachably attaching a cell 6 is fixed through a packing 8 to the threaded portion 7 at the center of the back cover 3. A space 13 formed continuously in doughnut shape is formed between the vibrating plate 9 and the back cover 3 to thus resonate the sound generated by the plate 9 in the space so as to radiate the sound externally from the sound radiating hole 14 formed at the back cover 3. A piezo-electric element 15 is disposed at the back of the plate 9 to thus drive the vibrating plate. Thus, the display surface can be freely designed, and the cell can be simply deteahed and attached with the hatch provided on the back cover.
