Abstract

PURPOSE:To enable remote control by a prescribed sound wave and enable the confirmation of the time even at a dark place, by providing a sound wave detection circuit in a digital timepiece. CONSTITUTION:A strut 22 is secured on a digital timepiece 23. An electric bulb, which is a light source, and a shade 21 are provided on the top of the strut 22. A window 22 is provided in the strut to absorb outside sound waves. A prescribed sound wave is transmitted to a microphone 1 of a signal processing circuit of the timepiece 23 through the window 22a. Only when the transmission of the prescribed sound wave to the microphone lasts for a predetermined time, a detection circuit 4 generates an output to energize a light emitter 11. The time indicated on the timepiece can be read by the light from the light emitter.
