Claim 13:
14. The apparatus for impact position detection of impact sport equipment according to claim 9, wherein the processor further retrieves, by the data retrieving apparatus, multiple vibration signals generated by the vibration sensor detecting vibrations generated by impact of the ball at multiple preset impact positions on the impact sport equipment; respectively perform a spectrum analysis on the vibration signals to obtain a plurality of eigenfrequencies of the vibration signals in the frequency domain; calculate the characteristic information by using the amplitude of each of the eigenfrequencies; and use the characteristic information as input of the prediction model and use the corresponding impact positions as output of the prediction model so as to train the prediction model and record multiple learning parameters of the trained prediction model in the storage apparatus.
