How does this work? If this is like a pea whistle, where is the pea? If it is a pealess whistle, it would need three chambers. Does it make the same sound?

eh? Why would a pealess whistle need three chambers? Even a pea-whistle without a pea works. The pea is only in there to get into circular motion by air pressure and open/close the opening differing the tune (basically the same way a sirene works); the function is like blowing over a bottle-head's opening or any other tube. The mouthpiece's end is straight in line with the edge at the other side of the opening splitting the air flow and bringing the whole thing to vibration.
Afaik that's how it works to make sounds, even with your voice; forcing air through more or less movable edges, strings and make them vibrate.
