A skateboard SB has a board 10 that is rotatably provided with a front
wheel 25 and rear wheel 26. Disposed on the both sides of the board 10
are speakers 12a, 12b. On the undersurface of the board 10 there are
provided a floor sensor 66 having a CCD camera for shooting a floor and a
distance sensor 67 for sensing the distance to the floor. A control box
13 disposed on the undersurface of the board 10 is 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
sensor 66 and the distance sensed by the distance sensor 67, 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.
