Schumann Resonator

I got 2 of these from Amazon...careful that free returns are applicable.  I charged them up, turned them on and holy moly.....they do help with my system.   What I hear is between instruments, a definite difference in upright and electric bass, wider know...all the good stuff. At first I thought it might be increased brightness, but is still the same in that regard.  I still can't believe it, and will listen again tomorrow (saved the packaging for the return)...but today, I'm about to keep them.
Think front of the Acustafan running in reverse would be easy..speakers tough. Tom
I don’t think the mobile devices or a speaker can produce the frequency needed.
But, good question about Qoboz.

So this thing sold on Amazon produces the frequency by physical moving parts rather than electronically through a speaker? I don't know much about how sound is produced, I just like to listen to music, so my question may not make any sense.  
This was a quote in 2019 from a formerly active poster who loves say the least:

To make things even more confusing the full 7.8 Hz signal from the Schumann CD can be put into the room by tiny computer speakers.
So if that's the case what does the CD do that the Amazon thing doesn't and vice versa?
And I'm not against things like this at all. I just want to know how they work.  This thing looks great and I'd love to try it were it not for the large price tag:
