Abstract
PURPOSE: To enable the generation of a plurality of alarm sounds and the like which can be discriminated from each other through the intermediary of a memory element having a small memory capacity by generating melody sounds with different tempos by a tempo varying means.
CONSTITUTION: AND gates 34W36 of a sound length controlling circuit 27 forming the tempo varying means are opened by set outputs of FF17, 18, 20, etc. which are set by a coincidence output of a plurality of alarm setting times, etc. and of the current time and a clock pulse counted by a counter 38 is selected. By this, the counting speed of the counter 38 changes and the time required so that the counter 41 reaches the counting of a prescribed value corresponding to the average length of notes through the intermediary of a matrix decoder 40 also changes. Accordingly, the same melody sounds through the intermediary of the memory part of musical- sound codes which are read out and controlled in accordance with the coincidence of the counted value of the counter 41 and the sound length code of the musical- sound memory part change in accordance with alarm set times with different tempos. As the result, by a simple constitution using memory elements with small memory capacity alarm sounds in plural which can be discriminated from each other are generated.
