Acoustic Mag Gen = Mag Resonance Amplifier 

Tinsel Koala is in the process of testing it, it would be interesting to watch his channel and it confirms what verpies has said.

Watch his videos here.

By the way if its overunity, jimboot should be able to charge his iphone by looping the output back to his iphone charging socket.

This sounds a little like the NMR and NAR project that was being carried out elsewhere.
I wonder how that ended up?. Ever seen what really happens to a wine glass when the right ARF is hit?.

It does. 
I always am amazed how much the glass can bend before it breaks.  I could not squeeze the glass so much in a vise statically.  It would break much earlier than the dynamic deformation shown on that video.

Tinsel has gotten to Part 6 already.  See here.

Note that his experiments are only about the electronic circuit behavior.  Effectively an LC tank and a transformer.
He does not investigate the stimulation of the ferromagnetic core by acoustic pressure.  Jimboot does not either.

You will notice that stimulation can occur without even touching the ferrite core !!

Yes but that is because the acoustic pressure vibrates the core through air vibrations.  The closer the piezo gets to the core, the "louder" it sounds to the core. 

If a sound barrier is placed between the piezo and the core then the magnitude of the acoustic influence through air decreases.
Maybe Grumage will show that on his next video.

Even after witnessing the acoustic dampening effect of Grumage's plastic bag, it should be clear that the piezo does not influence the magnetic field of the core directly ...or the piezo is not influenced by magnetic field of the core at a distance. 

The piezo can influence the magnetic field only indirectly - through its influence on the core's atoms. 
It is the core that is primarily  responsible for the magnetic field and the core's material must be vibrated by the piezo either by direct contact or via air (the former is stronger).

Finally, note that magnetic fields are almost completely confined in closed cores (toroidal cores or C cores or E cores or Pot cores, etc..) so almost no magnetic fields exist outside of such cores and nonexistent fields cannot influence anything.

P.S.
A good sound barrier consists of a hard reflecting layer (e.g. a rigid pane of glass, bathroom tile) sandwiched with a soft absorbing layer (e.g. polyurethane foam).  A metal plate makes a good reflecting layer, too, but it is not good for the sound screening test because it disturbs varying magnetic fields.

@verpies, it would be better to take a bar magnet and first determine its natural resonant frequency by the method given below.

http://www.google.co.in/url?sa=t&rct=j&q=new%20ferrite%20rod%20frequency&source=video&cd=2&ved=0CDUQtwIwAQ&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DdU0YO_U945c&ei=FsUEU7nRBMbDrAf4tYHgCg&usg=AFQjCNGJAfAe_9nBrYWlfZcZ9Bc1e5Mrig&sig2=2o3wJjfqXRVVMfSbnt0qkw

Second step should be to stick two piezo speakers on both end wired to increase the amplitude of the resonant logitudinal wave. The output from signal gen should be of same frequency. Fixed.

Third step should be to first test just the output of a coil would over the magnet to measure the acoustic resonance effect independent of the input in the primary. This will give a good insight of the acoustic electricity generation.

Fourth step should be to put the primary in series or parallel to the piezos to see where you get the max output.
