  • Dual-mode sound-producing toy
    Patent number: 4080754
    Abstract: A sounding toy with a rigid body of tapered cross section in both width and thickness produces a roaring sound when swung overhead at the end of a flexible cord. The roaring sound is enhanced by the reduction in thickness toward the outer end while the thicker base provides additional mass required for whirling. An aperture-type whistle communicating between the faces of the sounding toy imparts interesting variety to the sound.
