Golf club head with acoustic adjuster

Abstract

A golf club head includes 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.

1 . A golf club head comprising: 
 a body comprising a sole, a crown, and a striking plate, an inner space being defined by the sole, the crown, and the striking plate; and    an acoustic box mounted in the inner space and including at least one resonance plate to provide a stereo resonance effect, thereby altering a resonance modes and vibration modes of the body.    
   
   
       2 . The golf club head as claimed in  claim 1 , wherein the acoustic chamber is one of sealed and open.  
   
   
       3 . The golf club head as claimed in  claim 1 , wherein said at least one resonance plate includes at least one through-hole.  
   
   
       4 . The golf club head as claimed in  claim 1 , wherein the acoustic box is mounted to an inner face of the sole, the sole including an opening that also forms an opening of the acoustic box, the acoustic box including an inner periphery with an inner threading, the golf club head further comprising an adjusting member including an outer threading threadedly engaged with the inner threading, allowing adjustment of a volume of the acoustic chamber.  
   
   
       5 . The golf club head as claimed in  claim 1 , wherein the acoustic box is one of cubic, conic, truncated conic, and semi-spherical.  
   
   
       6 . The golf club head as claimed in  claim 1 , wherein the acoustic box is one of square, semi-circular, circular, trapezoidal, and polygonal in section.  
   
   
       7 . The golf club head as claimed in  claim 1 , wherein said at least one resonance plate is mounted to an inner face of at least one of a rear, a toe, and a heel of the sole.  
   
   
       8 . The golf club head as claimed in  claim 1 , wherein the body further includes a plurality of side plates, and wherein said at least one resonance plate is mounted to an inner face of at least one of a toe and a heel of the side plates.  
   
   
       9 . The golf club head as claimed in  claim 1 , wherein the golf club head further includes an inner acoustic box in the acoustic chamber, the inner acoustic box defining an inner acoustic chamber.  
   
   
       10 . The golf club head as claimed in  claim 9 , wherein the inner acoustic box has a shape the same as that of the acoustic box.  
   
   
       11 . The golf club head as claimed in  claim 9 , wherein the inner acoustic box has a shape different from that of the acoustic box.  
   
   
       12 . The golf club head as claimed in  claim 11 , wherein the inner acoustic box includes a tubular section and an enlarged head on an end of the tubular section.  
   
   
       13 . The golf club head as claimed in  claim 1 , wherein 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.  
   
   
       14 . The golf club head as claimed in  claim 1 , wherein the acoustic box includes a wave-like portion.  
   
   
       15 . The golf club head as claimed in  claim 14 , wherein the wave-like portion has a width greater than that of said at least one resonance plate.
