    • A golf club head having a translucent insert disclosed. The club head includes a body defining a striking face, a top line, a sole, a back, a heel, and a toe. The back contains a cavity that extends in a direction substantially perpendicular to the face. A recess is provided within the cavity, with the recess extending away from the cavity and toward the sole. The recess causes more of the club head mass to be oriented towards the perimeter of the club head, and optionally also toward the back of the club head. This enlarges the club sweet spot and increases the moment of inertia, and facilitates imparting a desired flight path to a struck golf ball, producing a more forgiving club. The recess may have a varying depth and/or a varying draft angle. A rear wall of the recess may be provided with a cutout to further reposition mass toward the club head perimeter. A translucent insert, such as a vibration dampening member, may be provided within the recess. The insert may contain secondary inserts, such as weight members, therein in strategic locations. The insert may completely fill the recess, or may fill only a portion thereof.
    • 公开了一种具有半透明插入件的高尔夫球杆头。 球杆头包括限定醒目面部,顶线,底部,后部,脚后跟和脚趾的主体。 背面包含沿基本垂直于面的方向延伸的空腔。 在空腔内设有一个凹槽,凹槽从腔体向底部延伸。 该凹槽导致更多的球杆头质量朝向球杆头的周边,并且还可选地还朝向球杆头的后部。 这增加了俱乐部的甜点,并增加了惯性矩,并且有助于给打击的高尔夫球赋予期望的飞行路线,从而产生更宽容的俱乐部。 凹部可以具有变化的深度和/或变化的拔模斜度。 凹部的后壁可以设置有切口,以进一步将质量朝向球杆头周边重新定位。 可以在凹部内设置半透明插入件,例如减振构件。 插入件可以在其中在战略位置中包含次级插入件,例如重量构件。 插入件可以完全填充凹部,或者可以仅填充其一部分。
