Abstract
An alarm electronic timepiece comprises a time circuit including a time standard signal oscillator for generating a time signal fed to a time display portion for displaying time. An alarm device is driven by an alarm driving circuit to produce an audible alarm sound. An alarm signal compound circuit develops a plurality of signals having different duty cycles and having a frequency in the audible frequency range, and serially arranges the plurality of signals in a predetermined pattern to form an alarm signal composed of the serially arranged signals of different duty cycles which is applied to the alarm driving circuit to produce an audible alarm sound having a predetermined sound pressure variation pattern.
