Abstract

A golf club head with sound tuning. The golf club head includes a hollow body that defines an interior cavity and a sound tuning feature inside the hollow body. The dimensions and location of the tuning feature are selected to alter the vibration behavior of the golf club head.

Claims

1. A golf club head, comprising:

a body including a crown portion and a sole portion and defining an interior cavity,

wherein the crown portion includes a first crown thickness area having a first crown thickness, a second crown thickness area having a second crown thickness that is greater than the first crown thickness, and a crown transition defining an interface between the first crown thickness area and the second crown thickness area,

wherein the crown transition is located on the crown portion at a location that exhibits at least 75% of a maximum displacement of a vibration mode having a frequency less than about 3600 Hz.,

wherein the sole portion includes a first sole thickness area having a first sole thickness, a second sole thickness area having a second sole thickness that is greater than the first sole thickness, and a sole transition defining an interface between the first sole thickness area and the second sole thickness area, and

wherein the sole transition is located on the sole portion at a location that exhibits at least 75% of a maximum displacement of a vibration mode having a frequency less than about 4100 Hz.

2. The golf club head of claim 1, further comprising a truss system, wherein the truss system comprises a first rib that intersects the first sole thickness area and the second sole thickness area.

3. The golf club head of claim 2, wherein the truss system comprises a second rib that extends from the first rib.

4. The golf club head of claim 3, wherein the second rib intersects the first sole thickness area and the second sole thickness area.

5. The golf club head of claim 1, wherein the crown transition has a length less than about 2.00 mm.

6. The golf club head of claim 1, wherein the crown transition is radiused such that the radius is tangent to the first crown thickness area.

7. The golf club head of claim 1, wherein the sole transition has a length less than about 2.00 mm.

8. The golf club head of claim 1, wherein the sole transition is radiused such that the radius is tangent to the first sole thickness area.

9. A golf club head, comprising:

a body including a crown portion and a sole portion and defining an interior cavity; and

a truss system that comprises a first rib disposed on the sole portion,

wherein the sole portion includes a first sole thickness area having a first sole thickness, a second sole thickness area having a second sole thickness that is greater than the first sole thickness, and a sole transition defining an interface between the first sole thickness area and the second sole thickness area,

wherein the sole transition is located on the sole portion at a location that exhibits at least 75% of a maximum displacement of a vibration mode having a frequency less than about 4100 Hz, and

wherein the first rib intersects the first sole thickness area and the second sole thickness area.

10. The golf club head of claim 9, wherein the truss system comprises a second rib that extends from the first rib.

11. The golf club head of claim 10, wherein the second rib intersects the first sole thickness area and the second sole thickness area.

12. The golf club head of claim 9, wherein the sole transition has a length less than about 2.00 mm.

13. The golf club head of claim 9, wherein the sole transition is radiused such that the radius is tangent to the first sole thickness area.

14. A golf club head, comprising:

a body including a crown portion and a sole portion and defining an interior cavity,

wherein the crown portion includes a first crown thickness area having a first crown thickness, a second crown thickness area having a second crown thickness that is greater than the first crown thickness, and a crown transition defining an interface between the first crown thickness area and the second crown thickness area,

wherein the crown transition is located on the crown portion at a location that is within about 15 mm of an area of maximum displacement of a vibration mode having a frequency less than about 3600 Hz.,

wherein the crown transition has a length less than about 2.00 mm, and

wherein the crown transition is radiused such that the radius is tangent to the first crown thickness area.

15. The golf club head of claim 14, wherein the sole portion includes a first sole thickness area having a first sole thickness, a second sole thickness area having a second sole thickness that is greater than the first sole thickness, and a sole transition defining an interface between the first sole thickness area and the second sole thickness area.

16. The golf club head of claim 15, wherein the sole transition portion is located on the sole portion at a location that is within about 15 mm of an area of maximum displacement of a vibration mode having a frequency less than about 4100 Hz.

17. The golf club head of claim 15, wherein the sole transition has a length less than about 2.00 mm.

18. The golf club head of claim 15, wherein the sole transition is radiused such that the radius is tangent to the first sole thickness area.
