I was wondering those headset jacks on your computer speakers, how much real power do they put out. The reason Im asking is I remember an experiment I did some years ago. I ran a program on my computer, a tone generator program,,that can make sine waves, square waves and so on,,it put these out as a tone, that could be heard on your speakers. I had a broke set of headphones. So I took the headset off then ran the wires to a transformer. On the secondary of the transformer I hooked up a motor. By playing around with the frequencies I got the motor to run. As I said its been some years back, I think the tone may have been around 1000hz that I used, but dont quote me on it. Point is I got the motor to run,,some frequencies made it run slower,,others faster, and most did not do anything at all to the motor. And I was wondering just what amount of power these headphone jacks put out. It was an amplifier type of speakers that I used that plugged into my computer sound card. But I also remember hooking a motor directly to headphone jack and the motor would not run, I even played music loud as the volume button would go and the motor would not run..That was directly connected to the jack. But by connecting the jack to the primary of a transformer,,and connecting the motor to the secondary of the transformer and using the tone generator finding the right frequency the motor ran... I can not remember if I used a diode on that secondary going to the motor or not, sorry. Anyway what do you think, how much power does those headphone jacks put out,,and why wont they power a motor directly,,without a transformer??
Steve,
The answer is, not much and, of course depends on the amplifier and the size of the speakers... BUT
I have long attested here that a SPEAKER IS AN OVERUNITY DEVICE.
Of course, I'm the ONLY person who sees it this way, so I am either nuts... or brilliant.
-------------------------------------------------------------------------------------------------------------------------
Here is why.
1. A speaker uses a dynamic/changing magnetic field to do it's thing.
2. IT TAKES ENERGY TO SET UP A DYNAMIC MAGNETIC SYSTEM.
3.This energy can calculated by doing 2 things to a speaker.
a Remove the Ferromagntic material from the coil (that moves the cone).. leaving just the coil.
b.Replace the Magnet with Coil.
4. You will realize at this point... that this modified speaker will work...
It will just take WAY MORE ENERGY energy to run,
compared with the regular setup that uses Ferromagnetics (which possess Unpaired electron Spin)
5. (Modified Speaker Energy) - (Regular Speaker Energy) = Energy supplied by the unpaired electrons.
My beef is Magnetic Permeability,
again.. I seem to be the only person ASTOUNDED
that a piece of Iron can Amplify the Field of Coil by 5,000 times,
Without using any extra energy ! (quoted from National Magnetics Lab in Florida).
Please see diagram below.
-------------------------------------------------------------------------------------------------------------------------
So you attached the output to a transformer and found different frequency worked different.
My guess it that you found Resonant.. and harmonic Frequencies that would make the motor work.
In other words...the motor is DC.. would you need just the right frequencies to get it to Turn with AC.
BUT... IF YOU RESONATE THAT TRANSFORMER.. well, that sucker (the transformer) would burst with energy..
to understand .. you just need to realize that an ACOUSTIC GUITAR AMPLIFIES THE STRING'S Vibration...
BY 1000 TIMES...
-------------------------------------------------------------------------------------------------------------------------
Again.. I believe I am way ahead of the curve on this.
It breaks down to this.
A room full of tuning forks...
I say that "by ringing 1 fork,, they all will ring louder and longer than if there was only 1 fork"
They say that "because of conservation of energy... the room full of forks will ring shorter.. because it's louder"
Anyways.. the second diagram shows how resonant cavities amplify a tone.

Observer, I've seen you mention some of this before. Are these concepts something you think can be used to build an OU device? Would it be a real world usable amount of power? I believe what you are saying but can't think of a way to make use of it. It seems if it was simple enough some of the people here would have taken it and run with it by now. Some people in the TPU threads are aware of the iron factor.
Would a room full of speakers respond to one stereo blasting away by generating power? I can see similarity there to some Don Smith and Dr. Stiffler devices.
stevensrd1, nice work on finding this resonance in a motor with an audio signal. I know very little about motors but wonder if larger motors might run this way. I know people who have spent many years working with all sorts of motors seeking OU so I'm going to guess this has been considered.
E2,
Basically, if you resonate a Transformer .. it bursts with power.
see image below.
Because speakers don't have a high Q Value (they don't ring without immediate vibrational input)
I don't think you could get the same effect as tuning forks... however
the cones will vibrate... thus producing power... and more speakers would mean more power.
But it wouldn't be like I picture OU since the Speakers will not ring on their own.

http://en.wikipedia.org/wiki/Line_level (http://en.wikipedia.org/wiki/Line_level) will tell you all about consumer devices (-10 Dbv) output, nominally about 0.3V
@stevensrd1
Why won't it run...They key to the operation of both electrical
and mechanical overunity devices is subsytem impedance matching.
Maximum energy transfer takes place only when the supply
subsytem and the load subsystem have identical impedances.
I'd estimate about one watt power at full volume. Which is about drain
current of about 200ma at 5volts. 1 volt p-p signal into 600ohms is
standard audio line drive. There is no reason you couldn't generate
60Hz sine waves at low voltage.
A room output speaker amplifier like a radio or TV is probably 10
watts and of course stereo amplifier the power is marked as rated.
It really has to do with the size of the final audio transistors and their
heatsinking capability. Those final transistors are usually on the
audio chip in a PC. It would be possible to get the specs on a
particular chip.

Here is another thought I had, relating to resonance. I took a piezoelectric crystal and layed it on a speaker,,and made the right tone that made it produce electricity, tho it was spiky voltage but high spikes of voltage. I wonder if we took and made two separate circuits,,each circuit full of many hundreds of these piezoelectric crystals. Now if we had an acoustic room,, put these circuits in there. Then start the right tone,,that then makes one set of piezoelectric crystals vibrate and produce a large amount of electricity,,then feed that electricity into the machine making the loud tone, would the sound keep the piezoelectric crystals resonating enough to keep producing the electricity to keep powering the tone generating machine, sort of a perpetual self powering device. Now as to the second set or circuit of piezoelectric crystals,, these could be used for a separate supply of electricity for any use,,since the same sound resonating the first set of piezoelectric crystals would be doing the same for the second set. Just a thought..
Steven,
As long as what you connect the piezos to.. will vibrate on it's own (high Q) ,
I believe your idea has some merit.
A speaker won't do that (it's damped) however.. yes it will vibrate.. but it will not store energy and vibrate on it's own.
