Abstract
A casing which accommodates an electric circuit for generating sounds of different tones or voice sounds has a recess 11 defined in its upper panel and a loudspeaker 12 disposed therein and mounted on the upper panel for reproducing and radiating sounds or voice sounds. A plurality of tone plates can selectively be placed, one at a time, in the recess. Each of the tone plates has dots and a bar code indicative of a sound or voice sound of its own. When one of the tone plates is inserted in the recess, the dots or bar code is detected by a sensor in the recess, and the electric circuit enables the loudspeaker to reproduce and radiate a tone or voice which is indicated by the inserted tone plate.
