The invention is a suspension element having an outer edge and an inner
edge. The suspension element, such as a spider or surround, varies in
shape along at least a portion of the suspension element to help relieve
both the radial and tangential stress placed on the suspension element
when it is stretched. The shape employed in the suspension element allows
the suspension element to stretch more easily, creating a higher
performance speaker of the same size by increasing the diaphragm
excursion and voice coil movement.
