Abstract
The present invention is directed to an improved acoustic speaker having a cone located about a transducer wherein the cone has a plurality a thin, pie-shaped segments radiating outwardly from the transducer with each of the segments having an accuated cross-section, thereby creating a concave side and a convex side. The segments are highly concave at the transducer and less concave with increasing radial distance from the transducer. The segments are made from a metal foil and the width of the segments may increase lineraly with radial distance so as to create a constant acoustical resistance radially. The segments preferably terminate at a flexible, high sound absorption ring.

In an acoustic speaker having a center, having a transducer located at said center and having a cone for conversion of electromechanical energy to sound located about said transducer, the improvement which comprises:
- a cone having a plurality of thin, pie shaped segments which radiate outwardly from said transducer, each of said segments having an arcuated cross-section, thereby creating a concave side and a convex side to each such segment, all of said concave sides of said segments facing one direction and all of said convex sides of said segments facing an opposite direction, and further wherein said arcuated segments have a highly concave cross section at the transducer and a less concave cross-section with increasing radial distance from the center of the speaker.
