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.

The housing body is threaded into an installation hole of the head unit, defines a receiving space, and has a base wall, a surrounding wall, an external thread for threadedly engaging the internal thread, and a recess formed in the base wall. The intelligent unit is received in the receiving space, and includes a 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 and exposes the charging electrodes.

Abstract: A golf club head includes a head body and a weight-balancing device. The head body is formed with a weighting recess. The weight-balancing device includes a coupling unit having a surrounding wall threadedly engaging the weighting recess, and an intelligent monitoring unit disposed inside the coupling unit. The intelligent monitoring unit includes a shell that is made of a signal-transmittable material and that is partially exposed form the surrounding wall, an intelligent monitoring element that is disposed in the shell and that is operable to detect data related to performance characteristics of a golf swing, and a wireless transmitter that is coupled to the monitoring element and that is operable to output the data.

Abstract: A golf club head includes a hollow head body, a metal plate, and a compression resistant plate. The hollow head body is formed with an opening. The metal plate is fixed to the hollow head body, covers the opening, and has a thickness ranging from 0.1 to 0.5 mm. The compression resistant plate is bonded to an inner surface of the metal plate and spans the opening.
