US Patent 10433523 Tennis ball toy with multiple sound features

A pet toy includes an inner layer or shell; an outer layer or shell; a noise producing center layer and a noise making element. When the outer shell is deflected or compressed by contact, the center layer is also deflected thereby producing a first sound. The noise making may be a squeaker supported within an interior chamber of the toy. When the outer shell is deflected or compressed by contact, the squeaker produces a second different sound.
