ABSTRACT:
A tune playing rotary toy comprises a centrifugally-actuated tune player comprising a casing (10) having a centrifugally-operable switch (30), an music synthesizer (32), and an energy cell (28). Upon rotation of the toy, it will experience centrifugal force, which will close the switch, which will in turn apply electrical energy from the cell to the circuit so that the stored tune will be emitted during rotation. The tune player may be mounted within or upon a toy gyroscopic top, e.g., of the stringless type (FIG. 1), or it may be self-contained with a spinner point and a manual spinning portion (FIG. 2B). The self-contained version may also be covered with sponge rubber (58) and attached to a twirling string (72) for swinging in a wide arc, preferably by means of a handle (78) on the end of the string opposite the tune player. The centrifugally-operable switch comprises a movable contact comprising a weight suspended at the end of a cantilever rod (42) and an L-, U-, or O-shaped fixed contact (38, 48, 50) for sensing motion of the movable contact in any of a variety of directions.
