Abstract
A rotary sound transducer having an improved output at higher frequencies. The invention includes stiff vanes that are preferably rigidly attached to a hub. A torsional actuator is provided in each vane. The torsional actuator selectively twists the tip portion of each vane. The torsional actuator for each vane is activated by an input energy source corresponding to the sound waves that are desired. The input force may also be electromechanical energy, purely mechanical energy, or some other form of energy.
