US Patent 11910174 Radially arcuated unistructural speaker cone with segmented dome

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.
