  • Patent number: 10984766
    Abstract: A sound generation angular velocity-adjustable twirling device detachably attaches to a fabric-article at a peripheral attachment point or a central attachment point and enables rotation of fabric-article. The fabric-article unfurls and twirls at a rate dependent on the center of gravity at different attachment points on fabric-article. A rod forms the central axis. A textured outer sleeve encapsulates the rod for secure grasping. A first axis positions in the outer sleeve, fixedly attaching to a first-rod end. A fastening mechanism rotates freely about the first axis while retaining the fabric-article. The rotating fastening mechanism and the stationary first axis form a rotational relationship with low friction coefficient. A second axis pins a strap to the second-rod end. The device generates sound while twirling through a gear assembly and/or percussion instruments. The sound generated is proportional to the angular velocity of the gear, and to the applied torque to the sleeve.
