Alarm electronic timepiece

摘要

An alarm electronic timepiece comprises an oscillating circuit for generating a high frequency reference signal which is frequency divided by a frequency dividing circuit into a lower frequency time signal. A display device displays information indicative of the present time in accordance with the time signal. An alarm counter is preset with the desired alarm time and a coincidence detecting circuit detects coincidence between the present time and the preset alarm time and accordingly provides an output signal which is fed to a buzzer for generating an alarm sound. Circuitry is provided for sounding the alarm in advance of the preset alarm time and at a low sound volume which gradually increases with the passage of time, such circuitry including a subtraction circuit connected between the alarm counter and the coincidence detecting circuit, a ring counter connected to receive the output signal from the coincidence detecting circuit, and a modulation circuit connected to the ring counter for modulating the signal applied to the buzzer.
