Abstract
A vibration damping device for stringed racquets including a viscoelastic member adapted to be mounted between strings of the racquet and at least one movable member carried on the viscoelastic member. The movable member is movable relative to the viscoelastic member in response to vibrations induced by an impact on the strings of the racquet such that the vibration damping device vibrates over the same frequency range but out of phase with the racquet to dampen vibrations in the racquet.
