Abstract
A golf club head includes a heel end, a toe end, a front face arranged to impact a golf ball, and a back face disposed rearwardly of the front face. A perimeter weighting element of increased mass protrudes rearwardly away from the front face and defines a cavity in the back face. The perimeter weighting element includes a top rail and a sole. A plurality of ribs are disposed in the cavity for eliminating undesirable vibrations in the golf club head when the front face impacts a golf ball and for attenuating other vibrations in the golf club head. Each of the ribs extends generally radially relative to the cavity from an inner end to an outer end that merges with the perimeter weighting element. An elliptically shaped geometric mass concentration is formed on a bottom surface of the cavity for assisting the plurality of ribs in eliminating the undesirable vibrations and in attenuating the other vibrations. The geometric mass concentration is surrounded by a depression formed in the cavity bottom surface, and the ribs extend across the depression.
