Abstract

PURPOSE:To enable confirmation of an alarm efficiently by the sense of physical stimulus in an electronic wrist watch with an alarm by vibrating a vibrator making direct contact with a human body by alternative alarm oscillation outputs having different vibration frequencies. CONSTITUTION:When an alarm setting time comes, an AND gate 8 is opened through a coincidence circuit 5 to apply predetermined alternative oscillation outputs having different frequencies from an osicllator 9 to the voice coil 15 of a vibrator 12 of an alarm unit 7 so as to transmit the vibrations alternatively varying the frequencies through the yoke 13 of the vibrator 12 making direct contact with a human body to the human body. Therefore, the alarm can be efficiently confirmed by the sense of physical stimulus on the human body.
