Acoustic magnetic generator.

[verpies]

"Claim 1:

An acoustic magnetic power generator composed of an alternating current signal connected to an acoustic transducer which stimulates the core of a permanent magnet such that the atoms of the magnet are caused to vibrate which in turn causes the magnetic field to vibrate and causes a current and voltage to be generated in an output coil wrapped around a permanent magnet or in the magnetic field of the permanent magnet which said current and voltage can be used for powering a load".

In fact this claim is explicit that the causal chain of stimulation is:
acoustic transducer --> atoms of the magnet --> magnetic field --> output coil --> voltage&current.


The conjunction "or" is there only to emphasize that the output coil does not have to be wrapped around the permanent magnet in order to be within the influence of the magnetic field generated by this permanent magnet.

From the Davidson patent:...
"The combined effect of the acoustic signal and the stimulating coil increases the efficiency of permanent magnet induction transformers".

This quote refers to TWO separate effects:
1) An acoustic stimulation of the ferromagnetic core
2) A magnetic stimulation of the ferromagnetic core.

Those two effects are stated to work in synergy for increased efficiency, but it does not mean that the acoustic stimulation of the core can be omitted.

The pure acoustic stimulation of the core is depicted in Fig.1 and Fig.2 of the patent.  In those figures the acoustic transducer is in physical contact with the core - not merely within the influence of its magnetic field.
Only Fig.3 and 4 add a second method to stimulate the core for improved efficiency... but it does not subtract the first method !

The patent is explicit that even in Fig.3 the acoustic field must be allowed to radiate into core (not into the magnetic field of the core):

The piezoelectric (1) is placed in close proximity to the permanent magnet (11) such that the acoustic field of the piezoelectric (1) can radiate into the permanent magnet material.

BTW: The magnetic field of Jimboot's transformer is contained inside the core, because the core is toroidal and forms a closed magnetic circuit.  Thus, the magnetic field in this core cannot even reach the piezo element, which is located outside of the core - not that it would matter anyway ...or be in accordance with the Davidson patent.

Again, from the Davidson patent:...
"When an alternating current signal generator is connected simultaneously to an acoustic transducer and a stimulating coil; whereby, both the acoustic transducer and the stimulating coil are located within the magnetic field of the magnet".

This is a quote from the patent's Preface and the author apparently did not put much effort to make it cogent.
This quote misleads the reader that the acoustic transducer does not need to transmit acoustic vibrations to the ferromagnetic core.
This is not only my opinion. The author tries to be more precise in the claim sections and contradicts himself on the same issue:

Claim 4:
"A method of maximizing the efficiency of permanent magnet transformers by stimulating the core material of the
permanent magnet transformers with both an acoustic vibration and an electromagnetic signal simultaneously."

THE PUNCHLINE:
According to the Davidson patent, the acoustic transducer (e.g. piezo element) MUST transmit acoustic vibrations to the ferromagnetic core material and it is not sufficient for this transducer to be merely in the vicinity of the core. 
Also, it is not sufficient for the acoustic transducer to be merely within the influence of the magnetic field created by the core.

However, the output coil can be merely in the vicinity of the core, as long as the varying magnetic flux generated by the core reaches it and cuts its windings.

Let me add that Jimboot wired a second piezo element in series with the first and tripled his output voltage!

Reply from Lasersaber to TK's new video:
"My scope showed .5V on the input before the transducer.  On the output side I found a sweet spot giving over 8 volts. 

Voltage is not power nor energy.
Voltage increase does not mean power increase.

My ball park COP calculation right now is 1:250!

How did you calculate that?
What is the maximum power output of this version of iPhone?
How much power is drawn by the load?

[verpies]

He demonstrated that his contraption didn't need a piezo transducer at four times the maximum acoustic frequency, and delivered zero output in the acoustic range

Why must the frequency be in the audio range?  Alas, acoustics does not need to operate in the audio frequency range.  Ultrasonics is still acoustics.
Tinsel used these high frequencies because his inductance was small, not out of malice.  If he had a bigger coil on hand then his frequencies would have been lower and in the audio range.

However Jimboot's system is only an electronic system - so the acoustic phenomena do not matter anyway. 
Jimboot's system is not magnetoacoustic because there is no acoustic stimulation of his core material. 
As such it is not even in accordance with the Davidson patent, which served as a model for Jimboot's device, AFAIK.

...which is what he set out to demonstrate as the chronic nauseating cynic he is. He shoot's from the hip at everyone and I hope I finally got to singe his tail feathers.

He might not be nice but as a scientist we have to pay attention to what he is writing, ...not how he is writing it.

The piezo circuit carries an exciter signal that's practically all voltage. There's no transformer level current running through it.

Capacitors behave the same way in LC circuits.  You need to measure the voltage across and current flowing through the piezo element to show that it indeed behaves differently.

The deception is that the piezo transducer is irrelevant in the circuit, and that it works the same when replaced by capacitors.
Jimboot just demonstrated that an additional transducer triples the voltage when making sound,

But that does not prove that a piezo works differently than a capacitor in that circuit.  Tinsel probably will make a 7th video which will demonstrate that an additional capacitor will also triple voltage at some point.  Then what?

BTW: Voltage is not power.  Voltage gain does not mean Power gain.
Also, in resonant LC circuits voltage is dependent on the value of capacitance and inductance, as shown below ...thus it is nothing unusual that changing the capacitance also changes the voltage.

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?.

Dear All.

Verpies suggested to me via PM that you guys and gall's might be interested in some of my findings using ultrasonic stimulation of a ferrite split core.

This is just one of a series of tests carried out using a very cheap Piezo transducer.   https://www.youtube.com/watch?v=Ql2zfs5vevM

I have since purchased some 40 W industrial transducers to continue my experiments with. The results will follow sometime soon.

You will notice that stimulation can occur without even touching the ferrite core !! You will also note that the Piezo transducer is not connected in any way to the output coils !!

Cheers Grum.
