Abstract
With a clip and a lower casing sandwiching a concha of a user so that the lower casing is positioned on the ear, a speaker generates a rhythm tone with a small volume in the vicinity of an ear hole of the user. A rhythm speed and type of the rhythm tone are set by operating switches with reference to a liquid crystal display. An integrated circuit has a memory device for holding recorded data of an analog sound and a reproducing device for reproducing an analog electrical signal from the recorded data according to the set rhythm speed and type to actuate the speaker.
