Vibration reducing golf club

Abstract

A vibration reducing golf club includes a club main structure and a plurality of piezoelectric materials. The club main structure includes a club shaft and a ball head and can sustain the mechanical energy resulting from the swing of the club shaft and the collision between the ball head and a golf ball and consequently produces vibration and bending deformation. The piezoelectric materials are connected with conductive wires and adhered to the club shaft. When the club shaft undergoes mechanical deformation, the piezoelectric materials can transform the energy of mechanical deformation into electrical energy, thereby producing a voltage output and then feeding the voltage back to another piezoelectric material, so as to produce a deformation against the vibration direction of the club shaft. Thus, the vibration energy of the club shaft can be consumed. Therefore, the vibration reducing performance can be obtained by reducing the vibration of the club shaft.
