The ball inside the whistle is not necessary for the whistle to work but serves a purpose. A whistle without a ball has a flat tone that may get "lost".
Air enters the whistle at one end. As the air reaches the other, closed end, all the air molecules "pile up" on top of each other and cause a high-pressure region. The air escapes out the little hole in the end, making the noise you hear. The frequency of the sound is dependent on the length of the whistle. The longer the whistle, the lower the pitch will be.

The ball causes a warbling sound by nearly shutting off the air passing through the whistle, and by varying the wavelength of the whistle slightly as it rolls around inside the chamber. Whistles without a ball produce a steady tone.
