Abstract: Loudspeakers having radiating diaphragms (16, 43) with a large surface-area and a high degree of rigidity. The diaphragm (26) is formed of a plurality of adjoining cups (31, 32), generally conical in shape, wherein two adjoining cups (31, 32) containing two families of reciprocal lines (28, 34) of curvature include a first family of boundary lines (34) connecting two upper points (24, 33) and a second family of lines (28) connecting two lower points (21, 29) of the cups, both families having their respective lines (28, 34) intersect at a "Saddle point" (30).
