摘要:
Disclosed is a racket (2) for ball games, comprising a frame which is formed by a profiled frame or a hollow profiled member and is provided with a racket head and a handle section that is connected thereto preferably via a core region. Two concavities (12) that are symmetrical relative to the longitudinal axis of the racket are embodied in the core region on the frame. A vibrating device (20) is arranged in each of the two concavities. Preferably, the vibrating devices of the inventive racket are effective for vibrations having at least two modes or two degrees of freedom. The invention further relates to a racket for ball games, comprising a frame which forms a head region for receiving strings and a handle section for holding the racket.
