Abstract: A vibration absorber assembly which includes a cantilever beam component having a proximal end and a distal end, wherein the cantilever beam component extends along a longitudinal axis between the proximal end and the distal end. A distal support element supports the distal end of the cantilever beam component, and an absorber mass is movable in at least a radial direction with respect to the longitudinal axis. First and second support media support the absorber mass with respect to the cantilever beam component. The first support medium contacts the cantilever beam component at a first support region of the cantilever beam component, and the second support medium contacts the cantilever beam component at a second support region of the cantilever beam component, the first and second support regions being located at different longitudinal positions along the cantilever beam component. Other variants and embodiments are broadly contemplated herein.
