ABSTRACT:
The present invention relates to an automatic sound-emitted self-learning toy characterized by effectively emitting the sound "YES" while the selected answer card coincides with the question card on the base sheet, and "NO" while the two are not in accordance with each other. The answer card, question card and basic sheet are provided with a magnet, when the corresponding magnets are located so as to be attracted to each other, the tape recorder within the rear body connected to the mechanism under the basic sheet will selectively emit the sounds "YES" or "NO" so that children may learn calculation while playing the toy.
