Abstract

PURPOSE:To obtain a small and lightweight watch capable of produding both alarm sound and time announcement sound by providing both alarm sound producing means and time announcement sound producing means constittued by electronic circuits and electro-acoustic transducers. CONSTITUTION:A counter part and control part 104 performs counting, controlling of the generation or not of time announcement sound and alarm sound and controlling of the sound production patterns of the time announcement sound and alarm sound upon receiving of the time anouncement signal, alarm start signal and manual signal from a watch part 103. A reference signal generating part 101 generates the reference signals for determination of the frequencies of the alarm sound and time announcement sound, the time intervals of each sound of the time announcement sound and the speed of striking the alarm sound. The acoustic signal which becomes the specified frequencies and having been subjected to the specified controlling by being applied with envelope by an envelope control arpt 105 passes through an amplifier part 106 and electro-acoustic transducer 107 and is outputted as the time annoucement sound or alarm sound. In this way, the small and lightweight watch may be obtained by the use of the electronic circuits.
