ABSTRACT:
Disclosed is a musical envelope-producing device which may be employed for an electronic watch with a melody performance function. The musical envelope-producing device has a memory which stores musical performance data representing pitches and durations of notes; an address counter; a pitch divider which generates a frequency signal corresponding to the pitch data; a note control circuit which divides a duration corresponding to the duration data into eight time components and generates a predetermined division signal when the duration has elapsed; and an envelope circuit which produces a sound pressure signal which is sequentially attenuated in a stepped manner in response to the division signal and which synthesizes the sound pressure signal and the frequency signal.
