5kHz is probably just a mechanical resonance from SM's wonderful hand-wound, unpotted coils.   This is undesirable in speaker coils.

The vibration is audible which puts in the range of hearing, so maybe he felt the need to explain it away.

Here's an interesting site that describes SPHERICS, TWEEKS, WHISTLERS, and you can hear them, etc..

I'm not saying this is how the TPU functions, but it's something to consider.

@ Grumpy

5kHz is probably just a mechanical resonance from SM's wonderful hand-wound, unpotted coils.Ã, Ã,  This is undesirable in speaker coils.

well I assumed thatÃ,  all along, that it was some resonance due to the dimension, but then recently, I got the impression all the different TPUs, of varing diameters, all functioned at 5 to 6 KHz.Ã,  Ã,  And he seems to reiterate that they extract energy from the "earth magnetic field, which has an INHERENT frequency"Ã, Ã,  It's a definite frequency, and "you tune to it" like he says.Ã,  Ã,  So, is this INHERENT FREQUENCY = 5 KHzÃ,  ?

So, haveing said that, this is not in opposition to having the device resonant.Ã,  In fact, it needs to be resonant at the same frequency for it to work effectively.Ã,  After all we tune antennas to be resonant at the desired frequency.

If we are to embark on the TPU as a Receiver, theory,Ã,  then the TPU is some sort of loop antenna that taps into a naturally occuring frequency.

OMEGA was a navigation signal operated by the US Coast Guard (in the United States) and other countries around the world. In the frequency range above 10 kilohertz, the signal could be heard as a repeating series of tones. On the spectrogram, OMEGA show up as a series of horizontal dashes of about one-second duration. Each of the seven OMEGA stations transmitted a unique pattern of four tones that repeated every ten seconds. OMEGA ceased operation in September 1997, done in by the advent of global positioning system (GPS) technology. Those of us who have studied VLF miss OMEGA a lot.

my interpretation ....... OMEGA cesed operation since the electric bill got too high all of a suden     LOL

Hi @EM

About the 5000hz, let's take a typical power generator. They usually turn at 1200 to 3600rpm or hz but they are forced drive and work against BEMF and this is why they produce energy. So if the tpu is basically a non physically moving rotor/stator system, cycles of 5000 or more would be frivolously easy to maintain. Such frequencies would be actually required because of the lower BEMP developed in non-moving rotor/stator systems, hence the lower power production. This also explain why you cannot drive an inductive load. So in these cases, a higher frequency would be required and considered normal.

I do not think there is any real link between the TPUs and the ether. It is using basic power production principles that are being employed and all talk by SM of the earth's energy field is another form of distraction designed to both provide the layman with a convenient and low end description of a plausible energy source. If you think the energy source is the Earths Fields, you are less likely to look for the real source inside the device and the scene is set for a more effective demo.

@Stefan

Dale Dolshal was SMs partner is the 3D sound in Spheric. Why not communicate with him and see if he has any pictures of Spheric Speakers. The photo posted above does not show the round grill from the inside so we cannot state if it was actually used in any of the TPUs.

@Vortex1

Thanks for the picture of the grill. Very good snooping around. Maybe if you can e-mail the person who posted it and ask him to take a picture of the inside of the grill, what material it is made of, etc. We would need to see the inside before saying it was used in TPUs.

@All

If I had an R&D dept., I would ask some to work on a new thread about non-transistorized pulsing methods. No SS components. How many ways can you pulse things without using a turning commutator or solid state components. What could be discovered in this new thread could be used here and elsewhere. I now it goes against the grain of most EEers but I think we have to consider this seriously.

Just an assumption
we know that (SM statements):
1) TPU "vibrate"
2) the frequencies are related to circumference of tpu

We know that SM in OTPU probably used woofer frames
reading at this link: http://www.speakerbuilding.com/content/1022/page_3.php

In Fig.3 we can see that duct tuning frequency is 38Hz (dip point between two peak at low frequency). Besides duct tuning frequency, one can see defeats of system. We can see some small ripples at 212Hz, 732Hz, 1367Hz, and 3960Hz. After some other experiments, I found the reason of each ripple.

212Hz ripple:

It's a resonance frequency of woofer frame. It doesn't happen when I measured a unit alone. It happens when installed on cabinet and It even can be felt by touching fingers to the frame. Excel woofer have only 4 screw holes on frame and frame is not well damped. I think SEAS have to consider to make more holes on the frame. To dampen that resonance, I attached damping materials to the back frame(See strips of Dynamat in Fig. 5. Treatment for woofer frame resonance) After that treatment it disappeared clearly.

They usually turn at 1200 to 3600rpm or hz

RPM is not Hz, far from it. RPM is Hz * 60.
