Default A truly alternative exotic DIY build. Worth a LooK!

Hopefully out of everything you have seen today, this has been the most original, though crude, exotic speaker driver you've come across???

Loosely designed using two existing technologies; Piston and Wave-bending. This is a Omni-directional driver I constructed earlier this year. Though it worked, it doesn't exist today as I dropped it - Butterfingers!

It wouldn't have won any awards, but the internal driver was interesting as it consisted of a brushless rotatory motor with mini magnets glued to the petals internally.

I hope it was worth a look.

I suppose thats one way to feel the music. With a high voltage van de graff generator.

Not bad looking.

Love to see your acoustic measurements. Not to mention performance specs for the mega-dollar commercial version.

Seems to me a pretty loopy way to try make precise sound waves (like low harmonic distortion that is expected of a quality driver). Half a dozen aspects of this cute design shout "not linear, not linear...." at least to my judgment from a distance.

Having said such unkind things, I would just ask, I wonder what we can learn from your experience or how to make such a device better?

It looks like it, except the individual bands aren't attached to each other in the MBL.

and the MBL does not use a rotary motor. but just plain old coils in rather common magnets as we know it .

but i cant seem to figure out where a motor would be in this design...


And HI ! James M Joppe here

Hey Joppe, The motors were within the petals. I may remake this in the near future, but the issue I had with this design was the size of the surface area of the resonator...
