The flow goes to step S 52 when it is determined that the golf club head strikes a golf ball, and goes back to step S 50 when otherwise.

  • the third reference distance range has a lower limit greater than an upper limit of the second reference distance range.
  • the first reference distance range is from 0 cm to 5 cm (including 0 cm)
  • the second reference distance range is from 5 cm to 9 cm (including 5 cm)
  • the third reference distance range is greater than or equal to 9 cm.
  • the processor 62 first determines which one of the first, second and third reference distance ranges the distance value (L) falls within.
  • the processor 62 determines that the impact one of the plurality of striking regions 241 - 247 is one of the surrounding regions 242 , 247 in the first group, and then determines which one of the surrounding regions 242 , 247 is the impact one based on a magnitude of the angular velocity or the torque (T).
  • the processor 62 further determines whether the magnitude of the angular velocity or the torque (T) is greater than a predetermined value, and then determines the surrounding region 247 as the impact one when the magnitude of the angular velocity or the torque (T) is greater than the predetermined value. Otherwise, when the magnitude of the angular velocity or the torque (T) is not greater than the predetermined value, the processor 62 determines the surrounding region 242 as the impact one.
  • the processor 62 determines one of the central region 241 and the surrounding regions 242 , 247 in the second group as the impact one based on the magnitude of the angular velocity or the torque (T); when it is determined that the distance value (L) falls within the third reference distance range (i.e., 9 ⁇ L), the processor 62 determines one of the surrounding regions 244 , 245 as the impact one based on the magnitude of the angular velocity or the torque (T).
  • the processor 62 controls the display module 63 to display the impact one of the striking regions 241 - 247 .

  • the interface of the application 610 may show the reference number, characters, symbols or the like assigned to the impact one of the striking regions 241 - 247 . For example, when it is determined that the surrounding region 245 is the impact one, the interface displays the reference number “ 05 ” that is assigned to the surrounding region 245 .
  • the processor 62 executing the application 610 can further calculate a track of the swing of a golf club provided with the golf club head, and the initial velocity, launch angle, flight distance, landing position and flight trajectory, etc. of the golf ball 5 based on the acceleration and the angular velocity of the head body 2 .
  • the golf club head can transmit, via the wireless transmitter 3213 , the acceleration and angular velocity of the head body 2 measured by the accelerometer 3211 and the gyroscope 3212 to the portable electronic device 6 , so that the portable electronic device 6 can implement the method to determine the impact one of the striking regions 241 - 247 that strikes the golf ball 5 upon impact.
  • the portable electronic device 6 can further display information about the impact one on the interface of the application 610 , so that a golf player using the golf club head of this disclosure and the portable electronic device 6 can adjust swing posture and strength so as to improve performance of playing golf.
