BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a golf club head. In particular, the present invention relates to a golf club head with an acoustic adjuster. [0003] 2. Description of Related Art [0004] U.S. Patent Publication No. U.S. 2004/0087388 A1 discloses a golf club head providing enhanced acoustics. 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. [0005] 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. OBJECTS OF THE INVENTION [0006] An object of the present invention is to provide a golf club head with an acoustic box providing a stereo resonance effect. [0007] Another object of the present invention is to provide a golf club head with a prolonged life while providing a stereo resonance effect. [0008] A further object of the present invention is to provide a golf club head with an acoustic adjusting member to alter the vibration modes and acoustic properties of the golf club head. SUMMARY OF THE INVENTION [0009] In accordance with an aspect of the present invention, a golf club head comprises a body and an acoustic box. The body includes a sole, a crown, and a striking plate. An inner space is defined by the sole, the crown, and the striking plate. The acoustic box is mounted in the inner space and includes at least one resonance plate to provide a stereo resonance effect, thereby altering a resonance modes and vibration modes of the body. [0010] The acoustic chamber may be sealed or open. The resonance plate may include at least one through-hole. [0011] 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. [0012] 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. [0013] 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. [0014] 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. [0015] 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. [0016] In yet another embodiment, the inner acoustic box includes a tubular section and an enlarged head on an end of the tubular section. [0017] 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. [0018] In yet another embodiment, the acoustic box includes a wave-like portion. The wave-like portion has a width greater than that of said at least one resonance plate. [0019] Other objects, advantages and novel features of this invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
