ABSTRACT:
A time signalling device for a timepiece in which the time signalling sound can be obtained in the same signalling sound with the mechanical time signalling means in which the previously produced sound remains to mix with the next sound, and the time signalling sounds in accordance with the more mechanical time signalling means can be electronically produced with good quality by having musical scale signal outputting means which simultaneously provides two musical scale analog signals of the melody sounds with the basis of two kinds of musical data read out of the ROM, by composing in such a way that each of these two musical scale analog signals can be alternatively output from these musical scale signal outputting means, by attenuating each of the output musical note signals for longer while than the time when the next musical note is produced, and, for the time striking sounds, by simultaneously outputting these two musical scale signals to be mixed.
