ABSTRACT:
A multi-purpose yo-yo structure has a body constituted by two identical disk members which are mounted on a mandrel and spaced from each other to define a gap therebetween for receiving a string wound thereon. Two dome-like cover members are respectively mounted on the disk members, each having a circuit board disposed therein. A plurality of light emitting diodes are mounted on the circuit boards to be controlled thereby and cells are provided to supply electrical power to the light emitting diodes through the circuit boards. Switches which are controlled by centrifugal forces generated by the rotation of the yo-yo are respectively disposed within the cover members to turn ON/OFF the circuit boards. A speaker is also provided within the yo-yo structure for generating a funny or exciting sound when the yo-yo is rotated.
