SWING SPEED MEASURING DEVICE OF GOLF CLUB HEAD BY USING RESONANCE CIRCUIT

摘要

PURPOSE: A swing speed measuring device of a golf club head by using a resonance circuit is provided by which swing speed data according to a swing sequence are compared and displayed through a plural displaying device by displaying a swing speed in a moment of impact when the club head hit a ball so users are able to swing at a regular speed with a stable maximum speed. CONSTITUTION: The device comprises: (i) a resonance circuit part which detects an amount of impedance change according to a conductive golf club head is approaching and a voltage signal regarding the amount of impedance change; (ii) an amplifying part which amplifies the detected voltage signal; (iii) a wave fixing part which outputs the amplified voltage signal as a peak wave in a form of pulse; (iv) a my-com which controls to perform a displaying action of a swing speed data by calculating a difference of time regarding the peak wave; and (v) a display part which displays the swing speed data according to the output signal of the my-com.
