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.
Claims44
Apparatus comprising:
- a loudspeaker suspension structure having an inner circumferential border, and an outer circumferential border, and
- grooves each extending form 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 have a continuous curvature.
An apparatus comprising:
- a loudspeaker suspension structure having an inner border, an outer border and a material thickness;
- grooves extending from the inner border to the outer border and separated by a groove pitch, the grooves having a radius of curvature along a circumferential section;
- and
- peaks defined between the adjacent grooves and having a peak radius of curvature along the circumferential section, the peak radius being less than about ten times the groove radius.
