Patent ID: 7431658

Claim:
A golf cup comprising: a cylindrical wall defining an interior and having a receiving opening on one end thereof, the cylindrical wall having a central longitudinal axis; a base wall fixed to the other end of the cylindrical wall and inclined relative to the cylindrical wall; an insert formed from a non-metallic material positioned in the interior and having a lower projection mounted to the base wall and a freely suspended portion integrally joined with an end of the lower projection and extending outwardly from the lower projection end; the freely suspended portion spaced from the base wall a distance along the longitudinal axis to form a first chamber between the freely suspended insert portion and the ball receiving opening and a second chamber between the base wall and the freely suspended insert portion; the second chamber forming a generally cone-shaped, unobstructed sound producing cavity; the freely suspended insert portion, the first chamber, and the second chamber are arranged and configured to effect an audible indication upon an object directly impacting the freely suspended insert portion as it resiliently flexes into the second chamber; and wherein the audible indication is achieved in the absence of metallic components but is similar to that achieved from a golf ball being dropped into a metallic golf cup buried in ground.
