<p>PROBLEM TO BE SOLVED: To provide a pleasant control toy in which music is generated at a tempo adjusted to a user's operation.SOLUTION: The control toy 10 includes: a sound-producing part 25 that generates music; a drumming surface 37 that a user beats while listening to music; a detector 38 that detects the beating of a user relative to the drumming surface 37; and a controller that, when music is generated, measures beating frequency detected by the detector 38 during a prescribed period and that adjusts speed of music generated by the sound-producing part 25 in accordance with the measured beating frequency. In this control toy 10, if a user's beating is fast relative to music, the music becomes fast and, if a user's beating is slow, the music becomes slow. Consequently, a music tempo follows up a user's beating tempo.</p> |
