1. A golf club head comprising:
- a face portion including an inner zone and an intermediate zone surrounding said inner zone, said inner zone having a relatively high flexural stiffness compared to said intermediate zone; and
a body portion connected to said face portion,wherein said inner zone has a generally elliptical shape with a major axis and a minor axis wherein said major axis aligns substantially in a direction of high heel to low toe,wherein said face portion contains a sweet zone encompassing said inner zone and said intermediate zone, andwherein no point within said sweet zone may have a COR that is 93% less than a maximum COR.

Abstract
A metal wood golf club head adapted for attachment to a shaft, comprising of a body portion and a crown portion, each portion constructed of a different density material. Combining a high-density material in the body portion, with a low-density material in the crown portion, creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. The material for the crown portion is preferably a composite. A vibration dampening gasket is disposed between the ledge and lip sections of the body and crown respectively.

11. A golf club head comprising:
-
a face portion including an inner zone and an intermediate zone surrounding said inner zone, said inner zone having a relatively high flexural stiffness such that a measurement zone, defined by a perimeter of said intermediate zone with a geometric center that coincides with a geometric center of said face portion, has a lowest COR that is at least 93 percent of maximum COR; a body portion formed of a material having a first density; a crown portion formed of a second material having a second density that is less than said first density, such that said club head has a center of gravity that is located below a horizontal plane containing said geometric center of said face portion; and a dampening layer juxtaposed between said body portion and said crown portion for acoustical attenuation between a frequencies of 3800 Hz and 10,000 Hz. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A golf club head comprising:
-
a face portion including an inner zone and an intermediate zone surrounding said inner zone, said inner zone having a relatively high flexural stiffness compared to said intermediate zone; a body portion connected to said face portion, and a shaft having a shaft axis concentric said shaft; wherein said face portion contains a sweet zone encompassing said inner zone and said intermediate zone, wherein said sweet zone encompasses approximately 15% to approximately 60% of said face portion, wherein no point within said sweet zone may have a COR that is 93% less than a maximum COR wherein said inner zone and said intermediate zone are non-circular, and wherein said minor axis is oriented orthogonal to said major axis such that said major axis forms an angle of between 10 degrees and 60 degrees with said shaft axis. - View Dependent Claims (19, 20)
