A sound producing rock having a matching body and a cap such that the cap is supported above the body in a spaced relationship to give the illusion that the cap and body are a monolithic structure. The cap and body are produced by sawing the cap from the body. A cavity is formed in the body by drilling a borehole in the body which extends downwardly from the flat body surface. A speaker is mounted in the cavity to project sound upwardly against the flat surface of the cap so that sound is projected outwardly from the space formed between the cap and body.
