Golf exercising aid device |
摘要 |
A simple golf exercising aid device for notifying a golf player immediately after any head-up. The device comprises sound pickup means for an impacting sound caused by the impact of a club head against a golf ball, first means which compares, with a threshold value, a waveform within a predetermined frequency band out of the signals provided by the sound pickup means and outputs the result after a predetermined delay time, a motion sensor made up of an earth magnetic field sensor or an angular velocity sensor, for converting the motion of a golf player's head into an electrical signal, and second means which rectifies and then differentiates the output signal of said motion sensor, and which compares the differentiated output with a threshold value. Said motion sensor is mounted a portion of the golf player's head, and judgment output is provided when the timings of the outputs from the two means agree.
