A constrained frequency resonator is incorporated into the shaft of a striking implement for transferring and, advantageously, amplifying momentum from a striking end to a gripped end of the striking implement, thereby amplifying the sensation of a strike felt at the gripped end. The resonator has a substantially hourglass shape, with wide ends and a narrow waist, and is made of stainless steel or another very hard material. The shape of the resonator causes it to act as a vibration frequency filter that transfers and, preferably, amplifies a certain frequency or band of frequencies. The striking implement may be a golf club, pool cue, or other implement in which frequency transfer to a gripping section is desired.
A striking implement having a shaft extending between a head and a gripping section, wherein the shaft includes a resonator having material properties and dimensioning tuned to achieve a desired resonant frequency upon impact to the head, and wherein the resonator is configured to transmit vibratory motion caused by the impact from the head to the gripping section at the resonant frequency.
A shaft for a striking implement, the shaft having a distal shaft section coupled to a gripping section by a resonator configured to transmit vibratory motion to the gripping section at a resonant frequency of the resonator, wherein the resonator has a distal end configured to couple to the distal shaft section and a proximal end configured to couple to one of the gripping section and a proximal shaft section, and wherein the resonator has a recessed section coupling the distal end to the proximal end and being tuned to effect a pre-selected amplitude and frequency band of the vibratory motion transmitted to the gripping section, the pre-selected frequency band including the resonant frequency.
A resonator for a striking implement, the resonator comprising:
