This is a funny question that I just had to take a stab at! :) I do not think it is actually the yawn that makes the noise, but most people stretch when they yawn. This is known as pandiculation. This is just a guess but when you stretch it tightens the vocal chords similar to the strings on a guitar. The yawn itself takes in air quickly which strum the chords (hope you can follow a metaphor, cause I can't think of how else to explain it) and produce the noise you hear when you yawn. This is why breathing alone does not cause the noise because the vocal chords are not tightened. Like if you were to try and play a guitar with very loose strings, it would make no sound. This is just a theory, but it is the best explanation that I have. :)
