ABSTRACT:
A sound source circuit is provided for a telephone terminal to reproduce chorus-effect imparted musical tones as incoming call sound or hold sound. Herein, original musical tone data ω c1are slightly modified in pitches to produce musical tone data ω c2with respect to a prescribed tone color. These musical tone data are periodically selected and synthesized together to form musical tone signals having a chorus effect, based on which the chorus-effect imparted musical tones be reproduced for the telephone terminal such as a portable telephone.
