Claims

[Scope of utility model registration request]

(1) A sound generation control circuit that outputs a sound signal for selectively controlling both pseudo-bird sounds and pseudo-insect sounds in an electronic alarm clock that performs a notification function with an electronic alarm sound at a preset time; a light detection means for detecting ambient light, emitting a pseudo bird sound when the ambient light is bright;
The electronic alarm clock is also characterized by emitting a pseudo-insect sound when the ambient light is dark.

(2) Utility Model Registration In the watch described in claim (1), the sound generation control circuit includes a sound generation ROM in which digital sound generation cycle data corresponding to pseudo-bird sounds and pseudo-insect sounds are written in different address areas. , an electronic alarm clock characterized in that the start address of any area is selected by the output of the light detection means.

(3) In the timepiece according to either of claims (1) or (2), the sound generation frequency control provides different preset sound frequencies for both the pseudo-bird sound and the pseudo-insect sound. An electronic alarm clock characterized in that a circuit is provided, and the light detecting means outputs a frequency control signal corresponding to each pseudo sound to periodically change the frequency of each pseudo sound.
