Abstract

PURPOSE:To prevent the phenomena that the sound volume of alarm is decreased in accordance with the change in the environmental condition, by providing a group of drive pulses of plural different frequencies. CONSTITUTION:There is provided a time memory 21 for storing the time signals which are fed to an alarm time setting input section 20. The condition of this memory is compared with an hour and minute counter 16 is time. A coincidence detecting circuit 22 transmits the electric signals, when the alarm time becomes coincident with the actual time, to the alarm sound generating pattern circuit 23 thereby to start this circuit 23. This circuit 23 constitutes the alarm sounds. The signals necessary for the tone, duration and pause of the alarm sounds are arranged and composed for the intended purpose by using the frequency-divided output from the frequency dividing circuit 15 of the watch.
