Abstract
The present invention relates to a method for producing a ringing tone of a telephone and a telephone, which comprises a sound generator for generating the ringing tone as a response to an incoming call, a memory for storing a signal representing the ringing tone, means for retrieving the signal from the memory and for inputting the signal into the sound generator for generating the ringing tone, and sound reproduction means for reproducing the ringing tone generated by the sound generator. In the method, information defining the ringing tone is input as characters, each character defining both pitch and duration of a tone and stored in the memory of the telephone, for which the telephone comprises means for inputting information defining the ringing tone as characters, each character defining both pitch and duration of a tone. Thus, a desired melody is produced as the ringing tone. Notes can be produced on a stave displayed on a display of the telephone. A user can input the desired melody either by means of keys and a menu or by means of a combination of specific keys.
