Acoustical feedback energy system

[stivep]

it may be out-of-phase depending on how speakers were wired.

We are assuming that speakers are connected exactly the same. red to red ,black to black. As you didn't change polarity in your original experiment right?

Well, it's not important how electrical signal is converted to pressure,

We are  collecting information now and not yet  formulating any conclusions

Well, I do not know how speakers were actually wired, to begin with, as this requires reverse-engineering, so I would not make any guesses as to which phase the pressure wave has. What's important is they were from the same manufacturer, so most probably they were wired equally.


You've touched the problem of noise-cancellation. And it is an observer-dependent effect. However, the energy from *both* waves is present at the point of observance, at the same time. But as the sum of pressure fields of stochastically-moving air molecules in both directions is zero this is *perceived* as absense of pressure. This is important, and it is also important to understand why I'm insisting that aether is a stochastic medium - it has the same property except scalar pressure field is replaced with complex electromagnetic field.

Dear Alex my time is very well paid in American dollars, and I'm dedicating it  to you for free.
We are not going yet to  the nonsense that makes sense for you.
We may, but not now.

So far we have   probable configuration of :
6 speakers in 3 pairs where  3   power cords were connected to the same electrical outlet 220V 15A fuse protected
Each pair had its own  amplifier .
If we  draw the circle  we would spread them equally on it but each pair of speakers is  facing each other in the straight line
drown through the center  of the circle.
Computer with the  sound card was connected to  separate outlet presumably from the same electrical phase.

Impedance match and load  specification:
In electronics, impedance matching is the practice of designing or adjusting the input impedance or output impedance of an electrical device for a desired value.
https://en.wikipedia.org/wiki/Impedance_matching

load by itself is specified in its general form as:
the quantity that can be carried at one time and also measured quantity of a commodity fixed for each type of carrier.
So  in the electrical outlet we have 220V potential and ZERO current.
The load will be measured by current drown from the outlet  and expressed by European formula P=U x I
where P is power in W   
U is 220V
and I (current in Amps) is  unknown yet.

So Load  needs enough  power  drown from the electrical outlet .
That has nothing to do with gain or amplification  or number of speakers or feedback
Load is a Load.
But if we don't have purely resistive Load we may expect that  Load  doesn't have fix value.
We know that  the bigger the load the  higher is the current drown from the electrical outlet 220V

So we may project that outlet as a big Russian guy having enough of power to carry on the load needs-
-like  if it was not  some resistive load but a pretty  Ukrainian teenager girl.
She wants this  she wants that, and  the guy happy or not must deliver.

Impedance vs changing value of the Load:
That pretty  Ukrainian girl requires  a maintenance  resisting  in many ways if not happy.
In  electronics  the Load can be  purely resistive at 10% but   in many ways if not happy
manifesting additional  capacitive or inductive reactivity at 90%
Your own picture  here: Re: Acoustical feedback energy system shows the transformer
from power supply mounted  in  one of the  every two speakers.
This transformer has   coils- means inductive reactance and  capacitive reactance  of the winding:
https://en.wikipedia.org/wiki/Gyrator%E2%80%93capacitor_model
and  you have 3 of these  transformers in your 3 pairs  ( total 6 speakers .)


At resonance, both capacitive and inductive reactance will be equal to each other.
The inductor and capacitor will also be conducting more current at the resonant frequency.
Current flowing across both components is 180° out of phase, which results in a mutually canceling current.
exploring-the-resonant-frequency-of-an-rlc-circuit

So we have  something that looks like short circuit blowing the fuse .
In other words you didn't have any gain, any magic energy produced,  you  just  sort of shorted the two terminals of that 220V outlet.
And by that  you are the double loser. You can't use your speakers at this   particular frequency and you don't have power in the outlet.
what-is-a-srf-this-is-used-in-ac-power-distribution-system-with-isolation-

The SRF is the frequency where the capacitive and inductive elements in the system are of equal magnitude and opposite sign.
This leads either to very low  impedances 
The effect is that the system does not work as intended. Keeping SRF well away from the operating frequency is a key design requirement.

To better understand  what I;m talking about  take look at the  DC and AC Relay. or  DC and AC electric door lock - the strike
A DC relay coil has resistance that limits the dc current.
An AC relay coil relies on its impedance for governing the current.
So it has few winds ~10% and ~90% is impedance

If you than decide to connect  the AC relay to DC voltage you will damage it as we speak.
Sometime it will blow in fumes.
because for DC that  relay or that electric lock doesn't  have any impedance - it Doesn't exist.

Additional  factor to know:
SWR of impedance match.
standing wave ratio (SWR) is a measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide
https://en.wikipedia.org/wiki/Standing_wave_ratio

If we don't want to explain the phenomena with use of   Counter-electromotive force (counter EMF, CEMF, back EMF), - the electromotive force (EMF) manifesting
as a voltage that opposes the change in current which induced it. CEMF is the EMF caused by electromagnetic induction.
we may  use -
The short explanation:
If There is no impedance patch to the load  than part of that energy   is reflected back and impacts the  source of energy   like Transmitter  of RF or the  outlet.
_____________________________________________________________


So you were not producing any magic energy but in  resonance  your power transformer  primary winding  had  more current than your outlet   fuse was able to withhold.
cheap Chinese design - that's all.

Note:
The electronic load  in tests : tests energy sources or energy conversion blocks with static or dynamic loading.

Yeah, I expected you would say "short-circuit", nothing new to see here. Except loudspeakers do not short-circuit when no signal is feeded into them, don't you think? From which heights the British unicorns bring you zero resistance in case of an opposing soundwave? And which is not a source of DC current?

weslie, please answer a question: will such loudspeaker (as I've used) short-circuit if the movement of the diaphragm be hardly constrained, or the voice-coil glued to the magnet?
