Oi, this website is currently on the move to https://turboflip.de - party on there!

Woven Speaker

a speaker made from a woven copper spiral with a magnet in the middle.
more turns for the spiral = better sound! make sure that the turns do not touch each other.

In my case i woven the spiral in a plastic cup (for better sound). But you can also use stiff fabrics and sew the spiral directly onto the fabric.

you can use an end piece for ground and the other piece from the end of the copper for the input. the order doesn’t matter.

(turn your audio to 100 % – it is reeeeally quite, because of the few turns of the spiral)


to get holes in the plastic mug, heat a needle over a candle and melt the holes in the mug

first try – failed because the material i used wasn’t stiff enough. (velvet)


for comparison on the left is a normal speaker 😉
