Abstract: An electroacoustic transducer which has at least one stator member (14, 16) with an operating surface (15, 17) and a suspended emitter diaphragm (12) spaced from the operating surface of the stator member to enable the diaphragm to oscillate in response to an applied signal voltage (19). The diaphragm has increased stiffness in a direction (31) along the diaphragm and within the emitter section to enable the emitter diaphragm to oscillate without applying tension in the direction of stiffness. A clamp member (22) secures the diaphragm to maintain the diaphragm in a fixed position relative to the stator to minimize distortion. The clamp member may be positioned to define several isolated emitter sections for enhancing the frequency response of the transducer.

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).
