Do you see the f-dependency without the resonator? If this is a problem of the experiment, just the sound without any resonance should show the same behavior. I just had a look at the file and it does not really do much, that could have an effect here. It creates a sine function that is sent to the speaker and the amplitude analysis is even simpler - it is the sum of the square of each sample.
I could imagine that the frequency dependencies of the speaker and mic might play a role here.
