Claims

[Scope of utility model registration request]

A crystal oscillator circuit that generates a reference signal as a time reference, a frequency dividing circuit that divides the frequency of the reference signal, a counter circuit that counts time, an alarm storage circuit that stores alarm time, the counter circuit, and the alarm In an electronic watch with an alarm that sounds a buzzer when the alarm memory circuit and the memory circuit match, the memory circuit stores the time at a fixed interval and outputs a signal when the memory circuit and the alarm memory circuit match the fixed time. a first ringing sound setting circuit that forms a ringing sound every fixed time when there is an output signal from the comparing circuit; and a first ringing sound setting circuit that forms a ringing sound every fixed time when there is no output signal from the comparing circuit. Second to do
An electronic clock with an alarm, which includes a sound setting circuit and is characterized in that a buzzer sound that sounds at fixed time intervals and a buzzer sound that sounds at other times are changed.
