A signal-emitting golf ball, having a chamber formed into its outer surface as a manufacturing step after the ball has been formed into its generally spherical shape. The chamber is of a form providing a reception chamber for the signal-emitting means being placed inwardly of the ball's outer surface at a manufacturing stage in which the signal-emitting means are not subject to ball-shaping or prior manufacturing steps. A novel signal-emitting device, shock-activated in nature, is provided to be silent through the practice swinging, but automatically emits a sound upon the ball being struck, and it keeps sounding until the player finds it and wishes it silent for the next shot, although preferably the sound is dim enough and steady enough so as to not be a bother.
