Thus, the welding sections of the stiffening member are subjected to forces of different magnitudes. As a result, cracks are apt to be generated. Thus, attachment of the stiffening member in the main body of the golf club head is not reliable and noise occurs easily while striking golf balls.

The golf club head has a hollow main body including a ball-striking face, a sole, a crown, a hosel, and a side portion extending rearwardly from the face. The body further includes a heel region adjacent to the hosel and a toe region opposing the heel region, and it defines a volume of at least 100 cc. The club head further includes a stiffening member disposed within the body and attached to both the sole and the crown. The member is spaced apart from the striking face and disposed within the body in a region having a first zone extending less than half the distance from the heel region to the toe region and a second zone extending less than half the distance from a rearmost point, thereby forming a local stiffness zone in the body to influence vibration modes and acoustic properties of the club head in a prescribed manner.
- However, the stiffening member only provides planar resonance. More specifically, the stiffening member could not provide a stereo resonance effect. Improvement in the acoustic properties is limited. Further, when the ball-striking face elastically deforms when striking a golf ball, the side portion, the sole, and the crown also elastically deform. At this time, since the stiffening member is welded to the sole, the crown, and the side portion and since the materials of the stiffening member, the sole, the crown, and the side portion are different from one another, the deformation extents of the stiffening member, the sole, the crown, and the side portion are different from one another. Thus, the welding sections of the stiffening member are subjected to forces of different magnitudes. As a result, cracks are apt to be generated. Thus, attachment of the stiffening member in the main body of the golf club head is not reliable and noise occurs easily while striking golf balls.
- An object of the present invention is to provide a golf club head with an acoustic box providing a stereo resonance effect.
- Another object of the present invention is to provide a golf club head with a prolonged life while providing a stereo resonance effect.

- The acoustic chamber may be sealed or open. The resonance plate may include at least one through-hole.
- In an embodiment, the acoustic box is mounted to an inner face of the sole. The sole includes an opening that also forms an opening of the acoustic box. The acoustic box includes an inner periphery with an inner threading. An adjusting member includes an outer threading threadedly engaged with the inner threading, allowing adjustment of a volume of the acoustic chamber.
- The acoustic box may be cubic, conic, truncated conic, or semi-spherical. The acoustic box may be square, semi-circular, circular, trapezoidal, or polygonal in section.
- In another embodiment, the resonance plate is mounted to an inner face of at least one of a rear, a toe, and a heel of the sole.
- The body further includes a plurality of side plates. In yet another embodiment, the resonance plate is mounted to an inner face of at least one of a toe and a heel of the side plates.
- In still another embodiment, the golf club head further includes an inner acoustic box in the acoustic chamber. The inner acoustic box defines an inner acoustic chamber. The inner acoustic box has a shape the same as or different from that of the acoustic box.
- In yet another embodiment, the inner acoustic box includes a tubular section and an enlarged head on an end of the tubular section.
- In still another embodiment, the acoustic box further includes at least one partitioning plate in the acoustic chamber for separating the acoustic chamber into at least two acoustic subchambers.

More specifically, theresonance plates 21 generate sound waves in various directions that are reflected in theinner space 10 to thecrown 12, thestriking plate 13, and theside plates 14. Thus, the stereo resonance effect of theacoustic box 2 may effectively alter the resonance modes and the vibration modes of thebody 1, providing musical striking sounds. Further, since theacoustic box 2 is merely bonded to the inner face of the rear of the sole 11 and away from thestriking plate 13, an improved strength is obtained.

In this embodiment, theacoustic box 2 has a width that decreases inward.FIG. 7 illustrates a fifth embodiment of the golf club head in accordance with the present invention.
