发明名称 Golf cup
摘要 A golf cup is provided that has a cylindrical wall defining an interior. The golf cup includes an insert formed from a non-metallic material positioned in the interior to form two chambers. The insert and chambers are arranged and configured to effect an audible indication upon an object, such as a golf ball, being dropped into the interior of the golf cup through the receiving opening. In one form, the audible indication is similar to that obtained from a golf ball being dropped into a metallic golf cup that is buried in the ground.
