ABSTRACT:
A skateboard SB has a board10that is rotatably provided with a front wheel25and rear wheel26. Disposed on the both sides of the board10are speakers12a,12b. On the undersurface of the board10there are provided a floor sensor66having a CCD camera for shooting a floor and a distance sensor67for sensing the distance to the floor. A control box13disposed on the undersurface of the board10is equipped with a computer device and a tone generator. The computer device controls, in accordance with the color and lightness of the floor sensed by the floor sensor66and the distance sensed by the distance sensor67, the generation of musical tone signals by the tone generator and the mode in which the musical tone signals are generated. A moving apparatus constructed as described above enables a player to listen to music that corresponds to changes in external conditions where the moving apparatus is placed, bringing more fun to the player without making the player tired.
