Abstract
An unistructurally formed acoustic speaker cone unit includes (a) a suspension ring with at least one continuous loop rib; (b) a central dome-shaped cone with thin, arcuate pie-shaped segments which radiate outwardly, and with a plurality of arc ribs; and (c) a main diaphragm having a plurality of segments radiating outwardly and extending to the suspension ring. Each main diaphragm segment has an arcuate cross-section, thereby creating a concave side and a convex side. The central cone segments are preferably equal in number to the diaphragm segments and are in alignment therewith.

An acoustic speaker cone unit for conversion of electromechanical energy to a broad range of audio frequency sounds, which comprises:
- said acoustic speaker cone unit being a single, unistructurally formed cone unit that includes:
- a) a suspension ring having a flat outer rim edge and a flat inner rim edge, and having at least one continuous loop rib;
- b) a central dome shaped cone, being a central diaphragm, having a plurality of thin, pie-shaped segments which radiate outwardly from the center of said central dome shaped cone, all 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 facing one direction and all of said convex sides of said segments facing an opposite direction, and wherein all of said arcuated segments have a highly concave cross-section toward said central dome shaped cone center and a less concave cross-section with increasing radial distance away from said center, and wherein said central dome shaped cone is convex towards said center, and wherein said central dome shaped cone has a base wall extending downwardly from said pie-shaped segments and connected to a plurality of segments of a main diaphragm;
- c) said main diaphragm having said plurality of segments radiating outwardly from said central dome shaped cone and extending to said inner edge of said suspension ring, each of said main diaphragm segments having an arcuate cross-section, thereby creating a concave side and a convex side to each such segment, all of said concave sides of said main diaphragm segments facing one direction and all of said convex sides of said segments facing an opposite direction, and further wherein said main diaphragm segments have a highly concave cross-section towards center and a less concave cross-section with increasing radial distance away from its center, and wherein each main diaphragm segment has a plurality of arcuate ribs, positioned concentrically relative to one another.
