Abstract:
A yo-yo toy structure comprising;a body having two identical disk members, each having an inner surface and an outer surface, said disk members being mounted on an axle in such a way as to define a space between two said inner surfaces of said disk members; a string which is loosely engaged around said axle within said space between said inner surfaces of said disk members; two dome-like cover members respectively mounted on the outer surfaces of said disk members; an electronic means disposed entirely within one of said disk members to measure a spin speed of said disk members in rotations per minute; an electronic means disposed entirely within one of said disk members to measure a duration of spin of said disk members; an electronic means disposed entirely within one of said disk members to calculate an overall score based upon a combination of the spin speed and the duration of spin; an electronic means disposed entirely within one of said disk members to calculate a scaled speed in miles per hour of said disk members and an equivalent distance; and an electronic sound transducer disposed entirely within one of said disk members to provide audio signals, tones, speech or audible sound.
