Abstract: A golf club head and a striking plate for connecting a shell of a golf club head are provided. The striking plate includes a plate body and at least one rib member. The plate body has a crown-connecting side, a sole-connecting side, a toe-connecting side, a heel-connecting side respectively connecting to a crown, a sole, a toe and a heel, a central portion surrounded by the crown-connecting side, the sole-connecting side, the toe-connecting side and the heel-connecting side, a front striking face, and a rear face. The at least one rib member includes two opposite end portions projecting rearwardly from the rear face, and a bridge portion connected between the two opposite end portions and spaced apart from the rear face.

Abstract: A golf club head includes a head body and a sensing device. The head body includes a mounting surface, a socket opening at the mounting surface, and a striking surface spaced apart from the socket and having a plurality of striking regions. The sensing device includes a housing removably mounted in the socket, and a sensing module disposed in the housing. The sensing module measures an acceleration and an angular velocity of the head body, and wirelessly transmits the acceleration and the angular velocity to a portable electronic device. When the striking surface strikes a golf ball, the portable electronic device determines one of the striking regions that strikes the golf ball based on the acceleration and the angular velocity.

Abstract: A golf club head includes a shell including a main body, a sealing cap, and a mounting receptacle, and an insertion unit. The main body defines an inner chamber and a chamber opening communicating with the inner chamber. The sealing cap is made of an electromagnetic-wave-penetrable material and covers the chamber opening. The mounting receptacle protrudes into the inner chamber from an inner surface of the main body and defines an installation space, and faces the sealing cap in such a manner that a normal projection of the mounting receptacle falls on an inner surface of the sealing cap. The insertion unit is detachably received in the installation space and includes an intelligent unit for measuring and transmitting data.

Abstract: A golf club head includes a head unit, and an insertion unit including a housing body, an intelligent unit and an encapsulant. The housing body defines a receiving space, and has a base wall, a surrounding wall, an external thread for engaging an internal thread of the head unit, a recess formed in the base wall, and multiple hollow portions formed in and extending between the base wall and the surrounding wall. The intelligent unit is received in the receiving space, and includes a first circuit board, two charging electrodes disposed on the first circuit board, and a capacitor connected to the first circuit board and the charging electrodes. The encapsulant is received in the receiving space, partially covers the first circuit board, and exposes the charging electrodes.

Abstract: A striking plate of a golf club head includes roughened textured surface portions and scoring line portions. The roughened textured surface portions are spaced apart from each other. Each roughened textured surface portion includes ridges. The scoring line portions are arranged alternatingly with the roughened textured surface portions. Each scoring line portion includes a sunken surface, a surrounding surface surrounding the sunken surface, and two connecting surface segments each extending from one end of the surrounding surface to connect to a respective adjacent roughened textured surface portion. The sunken surface cooperates with the surrounding surface to define a groove that extends along a line.

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.
