First Claim
1. A golf club head comprising:
- a strike face;
a back face opposite the strike face;
a heel region;
a toe region opposite the heel region;
a cavity integral with the golf club head; and
a filler material located in the cavity, the filler material comprising a density less than a density of the golf club head;
wherein;
the cavity comprises a back wall integral with the back face;
the cavity comprises an interior with a substantially tubular shape defined at least in part by the back wall and extending from the heel region to the toe region;
the cavity is substantially sealed off by the back wall from a rear exterior of the golf club head;
the cavity extends along a lower portion of the back face of the golf club head;
the cavity extends approximately parallel to the strike face;
the cavity is approximately symmetrical about a centerline that bisects the golf club head between the heel region and the toe region;
the filler material comprises at least one of;
a first filler density that decreases along the cavity from the heel region to the centerline;
ora second filler density that decreases along the cavity from the toe region to the centerline.

11. A golf club comprising:
-
a golf club body; a vibration dampening material; and a shaft coupled to the golf club body; wherein; the golf club body comprises; a front face; a back face opposite the front face; a heel region; a toe region opposite the heel region; a perimeter weight extending from the back face in a direction away from the front face and beyond the back face; a cavity comprising a substantially smooth interior with a tubular shape substantially continuous from an end of the heel region to an end of the toe region, the cavity extending along a lower portion of the back face of the golf club body at the back face, and about parallel with the front face and the back face; and a back wall integral with the back face and defining a portion of the cavity extends in an arcuate fashion from the back face towards the sole and substantially isolates the substantially smooth interior of the cavity from a rear exterior of the golf club body such that the cavity is accessible only at one or both of the end of the toe region or the end of the heel region; the vibration dampening material is located within the cavity and comprises; a first material comprising at least one of; a polymer material, a rubber material, a foam material, or a gel material; and a second material embedded within the first material and comprising a plurality of metal bearings; the golf club body is bisected at a centerline between the heel region and the toe region; and the vibration dampening material further comprises; a first density being at least one of; decreasingly dense along the cavity from the heel region to the centerline;
orincreasingly dense along the cavity from the heel region to the centerline; and a second density being at least one of; decreasingly dense along the cavity from the toe region to the centerline;
orincreasingly dense along the cavity from the toe region to the centerline. - View Dependent Claims (12, 13, 14, 15)
