  • Patent number: 8155341
    Abstract: In accordance with a traveling state of a vehicle, a tone indicating, for example, that the vehicle is traveling is generated as a tone of a first performance part. Also, a variation in any of various states of the vehicle, such as an operating condition of a winker or flasher, is detected, and a tone corresponding to the detected state is generated as a tone of a second performance part. For example, ensemble data including the first and second performance parts may be employed.

  • Patent number: 7633004
    Abstract: In a music reproduction apparatus designed for a listener to enjoy music while experiencing variations in vehicle status, plural types of phrases, which differ from each other, are assigned to plural tracks and are reproduced in accordance with reproduction parameters, which are controlled in response to vehicle status information. It is possible to control the setup values of reproduction parameters suiting vehicle statuses in response to travel environments. In addition, it is possible to synchronize the reproduction start timing of a music reproduction unit corresponding to one measure being reproduced by a first track with the reproduction start timing of a music reproduction unit corresponding to plural measures being reproduced by a second track. In a music information distribution system, a server stores music files including reproduction parameters suiting vehicle statuses and travel environments, so that the music reproduction apparatus reads them so as to reproduce corresponding musical tunes.

  • Patent number: 7067731
    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 ? c1 are slightly modified in pitches to produce musical tone data ? c2 with 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.

  • Patent number: 7058428
    Abstract: A portable telephone apparatus has a communication unit for receiving a call signal to inform a user of an arrival of a call so that the user can start a talk, and a reproduction unit for processing music data in response to the call signal to reproduce a piece of music composed of two or more parts including a melody part and an accompaniment part so as to audibly notify the user of the arrival of the call. Allowing the user to compose music without need for an excessive amount of work, score data for a melody is inputted first (IN1), and style information and chord information are inputted in the process of creating an accompaniment part. Then, accompaniment data for drum, bass and chord parts are selected from a ROM 12 or RAM 11 based on the inputted style and chord information (SE1). The selected accompaniment data of two or more parts are merged with the score data of the melody (PR1) to create music data.
