ABSTRACT:
Method and means to change the sound emitted from a metal "wood" golf club head by providing a first foward chamber in the head opening to the club head face, by providing a resilient face plate covering the first forward chamber and vibrating at a given primary frequency upon impact with a golf ball, and by providing a second rear chamber in the head disposed rearwardly of the first chamber and connected thereto by a throat whereby the second chamber and the throat have the function of a Helmholtz resonator modifying the sound propagated in the first forward chamber upon impact with a golf ball. The first and second chambers can be filled by a gas (such as air), a liquid, or a solid.
