A strung racket having a racket head in the form of a frame strung with stringing including longitudinal strings passing between a crown and a bottom of the frame and transverse strings extending transversely to the longitudinal strings between sides of the frame, the strings passing through holes in the frame. A device for damping vibration of the stringing generated by impact of the stringing with a ball, is provided and includes at least one pliable membrance fixedly received in at least one of the holes of the bottom of the frame and having an orifice tranversed by the respective string, the edge of the pliable membrane hugging the string traversing the frame hole.

Tennis racket with vibration-damping stringing

A tennis racket provided with a vibration damping device. The racket includes at least one pair of viscoelastic dampers, symmetric relative to a longitudinal axis of the racket and working in opposition. Each damper of the pair consists of a plate of viscoelastic material, whose one face is glued against the racket at a selected spot of the racket, and which includes on its other face a stress plate of rigid material. The selected spot corresponds to the antinode of a specific mode of vibration of the racket.
