<p>This invention relates to means for suppressing vibration in implements which serve to strike the ball and comprise a striking surface, a hoop which encloses the striking surface, and a handle. The invention relates particularly to tennis rackets and aims at suppressing the high-frequency vibration which is excited by the impact of the ball. In these striking implements, at least two longitudinal or transverse strings or at least one longitudinal string and at least one transverse string are mechanically coupled to each other by a vibration absorber.</p> |
