Abstract
A vibration damper device (1) intended to be mounted on a sports article such as, in particular, a tennis or squash racket, a gliding board or a golf club, wherein the device includes at least two elements (3, 4) superposed to form a stack and mounted so as to slide relative to one another, each element (3, 4) in said stack being secured to the article by one end, the ends (13, 14) of the adjacent elements being offset relative to one another so that the deformations of the article (8) due to the vibrations cause the adjacent elements (3, 4) to slide and at least one of the superposed elements (4) is magnetized, one of the other elements (3) in the stack being made of a material which is sensitive to the magnetic field generated by the magnetized element (4).
