Abstract
A golf club head including a front strike face, a sole extending rearwardly from a bottom region of the front strike face, a rear surface opposed to the front strike face, and a vibration damper provided on the rear surface. The vibration damper includes a constraining member having a high Young's modulus connected to the rear surface of the club head through an interposed visco-elastic material.

A metal wood golf club head comprising:
- a front strike face;
- a sole extending rearwardly from a bottom region of said front strike face;
- a top surface extending rearwardly from a top region of said front strike face;
- an arcuate skirt portion joining said top surface to said sole and extending from a toe region of said strike face to a heel region of said strike face, wherein the front strike face, sole, top surface and arcuate skirt portion define a cavity within the club head;
- and
- vibration damping means provided on the club head at a position other than on the front strike face, comprising constraining means connected to the club head by a visco-elastic material, said constraining means comprising a rigid plate having a Young's modulus greater than 10,000 MPa and a thickness between 0.07 and 2.0 mm.
