ABSTRACT:
An improved method and an apparatus uniformly transmit sounds over large angles of coverage. An acoustic source is attached to a loudspeaker horn with two straight outer side walls and two straight upper and lower outer walls, the projected extensions of which converge at an intersection point behind the acoustic source. The loudspeaker horn also has two inner side walls, and upper and lower inner walls which curve inwardly to the point of attachment with the acoustic source. The sound waves emanating from the loudspeaker horn have an apparent point of origin at the intersection point behind the acoustic source. A plurality of such loudspeaker horns and acoustic sources are positioned in a radial array so that all of the apparent points of origin of the loudspeakers are substantially coincident, creating a coherent signal without interference from overlapping sound waves produced by adjacent loudspeakers.
