Golf ball

Abstract

A golf ball includes a ball body having a central portion formed with a through hole. Thus, the golf ball produces whistle like audible sound by provision of the through hole of the ball body during rotation of the ball body after the golf ball is hit, thereby enhancing the playing amusement of the golf ball. In addition, the golfer can find the location of the golf ball by the audible sound produced by the ball body so as to shorten the time required for searching for the golf ball, thereby facilitating the golfer playing the golf ball.
