Abstract
A timepiece of the type including a time indicating circuit and an electronic alarm sound generating means. The alarm sound generating means including a counter outputting a sound switching signal at every predetermined time by counting the pulse signal of the time indicating circuit, a switch-over circuit consisting of a flipflop group for supplying the sounding number switch-over signal to preset the sounding numbers which are performed at a fixed period by the sound switching signal, a preset counter counting for a fixed pulse signal of the time indicating circuit and a value which is determined by the sounding number switch-over signal, a waveform convertor for outputting a preset control signal which presets the preset counter at every fixed period by utilizing the pulse signal from the time indicating circuit, a gate means for outputting the fixed pulse signal together with an audible frequency signal by the time the preset counter is counted up by the fixed pulse signal after the preset counter is preset, and an electronic sounding circuit performing the sounding action of the signal from the gate means, whereby an electronic alarm sound generating means for a timepiece can change its sounding numbers and intervals repeatedly at a fixed period and at a determined time.
