ABSTRACT:
In a communication apparatus which announces reception of a call by a melody sound, a memory preliminarily memorizes musical tone information data representing tone names of a number of musical tones and tone name frequencies of the tone names, respectively, and preliminarily memorizes musical note information data representing a number of musical notes and time values of the number of musical notes, respectively. The apparatus includes a radio signal processing part for receiving and processing a radio signal sent by a caller which includes a sequence of information pairs, each information pair including one of the number of musical tone information data and one of the number of musical note information data. A producing part produces a musical tone pattern signal having a sequence of frequency-time value pairs by reading, from memory, each frequency-time value pair. The musical tone pattern signal is for use in deciding the melody in response to a recognized call.
