Acoustical feedback energy system

This is a diagram of my 2011 experiment (circles here represent sound waves). It's very simple, you need 40 dollars for materials. The speakers presented here are usual cheap computer speakers; you can connect the speakers to the sound card of your computer: there will still be no feedback on them. The feedback will go to the tee; nuances in the sound amplifying cascades are possible - the speaker may also burn out. Note that loudspeakers are both emitters and absorbers of acoustic energy; it is an acoustic feedback system. Why 108 cm between the centers of the speakers - I don't know, I just wanted it to be so; in Buddhism the number 108 is sacred. I'm not seeing much sense myself in making a full-scale model again: hearing the clap of a fuse is not very interesting, and I am not capable of anything more in electrical engineering, alas. The frequency of the sinusoid must be carefully selected: at some frequency a "miracle" of electric energy feedback will happen.

It cannot be patented.

One thing worth exploring about this system is. While signal-amplifying cascades of speakers try to move the speaker cones to produce sound waves, they are opposed by sound waves coming from opposite speakers. This creates an electrically unresolvable tension, a singularity I would say.

It will depend on phasing. Depending on the diameter of the circle and the frequency, they could cancel, partial cancel, reinforce or rip the cones to shreds.

If you want to use the voice coils as generators, you will need some fancy switching.

In my experiment it wasn't too problematic for 10W-rated speakers. Only the fuze rated 15A on an electric tee blew. Which is of course totally unexpected. I do not think speakers started to draw 3KW, they would burn to ashes.

This could be an inductive spike. it could be quite significant.
