A multi-mode vibration absorbing device for implements includes a base member and a mass mounted to the base member and cantilevered relative thereto. The multi-mode vibration absorbing device is tuned such that it vibrates at the same frequency as the implement but out of phase therewith.

A vibration damping device for stringed racquets includes a viscoelastic member adapted to be wrapped around at least a pair of strings of the racquet and a moveable member extending through the viscoelastic member moveable 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 damp vibrations in the racquet.

A vibration damping device for sporting implements includes a base member and a mass mounted to the base member and cantilevered relative thereto, the device is tuned such that it vibrates at the same frequency as the sporting implement but out of phase therewith.

Vibration damping device for sporting implements

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.
