发明名称 Racket with capability of vibration absorption
摘要 A racket includes a frame having a rim and a connection portion at an end of the rim, a handle fixed at a distal end of the connection portion, an elastic member attached on a predetermined portion of the frame, and a cover layer wrapped around the frame and the elastic member. The vibration wave transmission velocities of the frame, the elastic member and the cover layer are different from one another and the vibration is therefore reduced while transmitting therethrough.
