Hi everyone .
some time ago on this forum I saw an acoustic transducer. I can't find the right link again, I don't know what it is and I don't know in which section I've seen it. it consisted of two empty cardboard cylinders, between them near and parallel, and presumably a third behind them, inside these cylinders there was something long and thin in coincidence with the axis of the paper cylinders, perhaps a electromagnet, from the appearance I deduce that it is self-made.
do you know what it is?

Hi, it's from this morning time that I'm trying to recall it, and now it comes:
The Rubanoid !
Is this it ?

Here is a long thread, with some pictures on the last couple of pages.
A DIY Ribbon Speaker of a different Kind

but it was very similar maybe it's a rubanoid.
so it's a DIY tape?
and how does it sound?
thank you very much, very kind.
