<P>PROBLEM TO BE SOLVED: To allow generated tones of even the small volume to be heard without fail by including information exclusive of physical amplitude and frequencies into the rhythm tones of a rhythm device for wearing on ears and by expanding the range of the comfortable volume of the tones to be produced at about users' ears. <P>SOLUTION: A speaker 15 generates the rhythm tones of the small volume immediately near the auditory meatus while putting the auricle between a clip 21 and a lower casing 12 and situating the lower casing 12 on the ear plane. The user references a liquid crystal display 17 and sets the rhythm speeds and kinds of the rhythm tones by operating switches 19 and 20. An integrated circuit 16 reproduces analog electric signals from sound recording data according to a memory means for holding the sound recording data of the analog tones and the set rhythm speeds and kinds and drives a speaker. <P>COPYRIGHT: (C)2004,JPO |
