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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The acoustic speaker cone unit of claim 1 wherein there are an even number of main diaphragm segments. ### Claim 3 (depends on 2) The acoustic speaker cone unit of claim 2 wherein there are ten to thirty main diaphragm segments. ### Claim 4 (depends on 3) The acoustic speaker cone unit of claim 3 wherein there are fourteen to twenty-two main diaphragm segments. ### Claim 5 (depends on 4) The acoustic speaker cone unit of claim 4 wherein there are eighteen main diaphragm segments. ### Claim 6 (depends on 1) The acoustic speaker cone unit of claim 1 wherein each of said plurality of main diaphragm segments has at least two arc ribs, and further, wherein the number of arc ribs on each increase with increasing size of said acoustic speaker. ### Claim 7 (depends on 6) The acoustic speaker cone unit of claim 6 wherein each of said plurality of main diaphragm segments have four to ten arc ribs. ### Claim 8 (depends on 7) The acoustic speaker cone unit of claim 7 wherein each of said plurality of main diaphragm segments have four to six arc ribs. ### Claim 9 (depends on 6) The acoustic speaker cone unit of claim 6 wherein said main diaphragm segment arc ribs have semi-circular cross-sections. ### Claim 10 (depends on 6) The acoustic speaker cone unit of claim 6 wherein said main diaphragm segment arc ribs have a sequentially increasing size as determined radially from center outwardly. ### Claim 11 (depends on 9) The acoustic speaker cone unit of claim 9 wherein said main diaphragm segment arc ribs have a sequentially increasing size as determined radially from center outwardly wherein said size is increasing linearly with increasing radial distance. ### Claim 12 (depends on 6) The acoustic speaker cone unit of claim 6 wherein said main diaphragm segments each have at least one radial rib that intersect at least one of said main diagram segment arc ribs. ### Claim 13 (depends on 1) The acoustic speaker cone unit of claim 1 wherein said main diaphragm segments have a lessening concave cross-section with increasing radial distance from the center of the cone whereby the width of the segment increases linearly with increasing radial distance so as to create constant acoustical resistance radially. ### Claim 14 (depends on 13) The acoustic speaker cone unit of claim 13 wherein there are eighteen main diaphragm segments. ### Claim 15 (depends on 1) The acoustic speaker cone unit of claim 1 wherein said at least one continuous loop rib of said suspension ring is a single continuous loop rib. ### Claim 16 (depends on 15) The acoustic speaker cone unit of claim 15 wherein said single continuous loop rib is located on said ring inner edge of said suspension ring. ### Claim 17 (depends on 16) The acoustic speaker cone unit of claim 16 wherein said outer edge of said suspension ring has a shape selected from the group consisting of round, oval, rectangular and polygon. ### Claim 18 (depends on 1) The acoustic speaker cone unit of claim 1 wherein said outer edge of said suspension ring has a round shape. ### Claim 19 (depends on 1) The acoustic speaker cone unit of claim 1 wherein said acoustic speaker cone unit is a unistructural plastic acoustic speaker cone unit. ### Claim 20 (depends on 19) The acoustic speaker cone unit of claim 19 wherein said plastic is polyvinyl chloride.
