Abstract
In general, the invention comprises a device capable of emitting either acoustic or electromagnetic radiant energy. The device has at least one reflector with a smooth concave surface which reflects the energy emitted from the transducing element. The device also has at least two transducing elements for producing this energy. The shape of this reflector surface is preferably defined by either an ellipse or a parabola that is rotated about an axis of revolution, for any angular distance between zero and one complete revolution. The shape of this reflector surface can also be preferably defined by the coincident surfaces of revolution of an ellipse and a parabola that are rotated about a common axis of revolution.
