ABSTRACT:
A loudspeaker suspension structure has an inner circumferential border, and an outer circumferential border, and grooves each extending from the inner circumferential border to the outer circumferential border at an angle with respect to a normal to the inner circumferential border, a profile of a circumferential section of the suspension structure having continuous curvature. Each of the grooves varies from the inner border to the outer border, the variation corresponding to a variation of a principal contour of the suspension structure.
