Golf club having vibration damping device and method for making same

摘要

A golf club (10) having a vibration damping device including a club head (12), a shaft (16) connected to the club head (12) having resonant frequencies over a predetermined range and a rod (20) disposed within the shaft (16) with a viscoelastic material (22) interposed between the shaft (16) and the rod (20). The rod (20) is flexible and has resonant frequencies over the same frequency range as the shaft (16) such that the shaft (16) and rod (20) vibrate out of phase with respect to each other and thereby deform the viscoelastic material (22) to damp vibrations in the shaft (16).
