Abstract
A golf club head includes a striking face including an exterior surface having a lower leading edge and an opposite upper topline edge, and an interior surface opposite to the exterior surface; a sole extending from the lower leading edge and having a rearward portion opposite to the lower leading edge; a back portion coupled between the upper topline edge and the rearward portion; a cavity at least partially enclosed by the striking face, the sole, and the back portion; and at least one constrained damping layer on the interior surface of the striking face.
Claims20
A golf club head, comprising:
- a striking face having an exterior surface having a lower leading edge and an opposite upper topline edge, and an interior surface opposite to the exterior surface;
- a sole extending from the lower leading edge and having a rearward portion opposite to the lower leading edge;
- a top portion extending from the upper topline edge;
- a back portion coupled between the top portion and the rearward portion of the sole;
- a cavity at least partially enclosed by the striking face, the sole, and the back portion;
- a support arm extending at least partially through the cavity from at least one of the top portion or the sole;
- a damping element positioned between the support arm and the interior surface of the striking face and directly contacting both of the support arm and the interior surface of the striking face;
- and
- a first constrained damping layer comprising a metal or a carbon fiber directly attached to the interior surface of the striking face by an adhesive, the first constrained damping layer being spaced apart from the damping element, and a rear surface of the first constrained damping layer being entirely exposed to the cavity.

- a damping layer directly contacting the interior surface of the striking face and covering a center of the striking face, the damping layer comprising a polymer;
- a support arm extending at least partially through the cavity from the body, and directly contacting a rear surface of the damping layer;
- and
- a constrained damping layer spaced apart from the damping layer, the constrained damping layer comprising a metal or a carbon fiber directly attached to the interior surface of the striking face by an adhesive, and a rear surface of the constrained damping layer being entirely exposed to the cavity.
