Abstract
A sound producing ball includes concentric inner and outer ball elements and a plurality of sound producing particles in an open area therebetween. The sound producing particles are dimensioned to travel in the open area when the ball is rotated, and the inner ball element has a plurality of projections thereon for redirecting the sound producing particles as they travel in the open area. The sounds produced by the sound particles as they strike the inner and outer ball elements are generally similar to the sound of rain striking a building roof.
Claims7
A sound producing ball comprising:
- a hollow outer ball element comprising an outer shell having a continuous inner surface thereon;
- an inner ball element comprising an outer shell having a continuous outer surface thereon secured in spaced substantially concentric relation in said outer ball element such that the outer surface of the inner ball element and the inner surface of the outer ball element are in substantially uniformly spaced relation and cooperate to define an open area therebetween;
- a plurality of discreet relatively hard sound particles in said open area, said sound particles being dimensioned to loosely travel in said open area when said ball is rotated;
- and a plurality of projections on at least one of said inner and outer ball elements extending into said open area for redirecting said sound particles as they travel in said open area, said projections being closely spaced in an array extending around substantially the entire outer surface of said inner ball element.
