Abstract
PURPOSE:To make thin the watch and to lower the cost, by incorporating the external cover and middle cover of the doble back covers, in the alarm watch outputting sound from the back cover. CONSTITUTION:The external cover providing the sound hole 7a is linked with the middle cover 8 with the pin 9 and unified. The sound transmitter is fitted to the middle cover 8 with the set ring 8b and sound is outputted through the sound hole 8a. The thickness can be made thin with the linking of the middle cover 8 with the external cover 7 with the pin 9 so taht the rigidity is mutually aided, and low cost can be made with injection molding by plastic.
