Paper Speakers (copper tape as coil)

[@losarchivosdelprofesortrum7987]

How did you manage to curve the tape without getting wrinkles?? :O

[@GraemeWolfendale]

Ah cool, this makes sense. I'm not to hot at physics, but I can remember learning about forces at right angles. We used our thumb, index, middle fingers to visualise this.

[@ILikeWeatherGuy]

your right, copper isnt magnetic, but theres pulses of electricity that run along the copper , temporarily making it have a magnetized pole which either attracts/ repels the copper, and since it is on paper, it then pushes and pulls on the paper, causing vibrations, and vibrations are sound so voila! sound xD

[@becurbilyg]

tutorial PLEASE!!! very nice! if i make the speaker-paper can i use another device and cut the wires that lead to the speaker and then connect them to mine or it will broke down because of the high voltage of the other device? (device like cellphone or mp3..)

[@tjgkuragari]

This must be how musical cards are made.

[@manudonosol]

Nice! can you share which magnet did you use? please :)

[@boxritter]

Where do you get that amp that lasts even if you shortcircuit it

[@AAAZ2A]

I can't see me lovin' nobody but you. For all my life.

[@JayRingel]

Did you take that singing toy's circuit board apart or was it from something else?

[@MrEngelhertz]

what is attached to the amplifier ? What do you use to play the music? Can you just use your phone for example as amplifier and connect it to the spiral ?

[@AureliusS]

Daniel Stoyanov Thats pretty much feal deal, works with cinch cable

[@miguelchacon2717]

Can aluminum foil be used?

[@mystix6705]

this piece of paper with this tape of coil is like a electromagnet? or how it works?

[@zer0b0t]

The coil acts as an electromagnet, the audio signal is AC (alternates between positive and negative) so the magnet interacts with the coil as the coil is attracted and repelled depending if the charge is positive or negative.

[@EddSjo]

That is probably because the resistance is smaller inte the small ones, thus resulting in a greater electric current and stronger electromagnetic field.

[@mcnimi]

what functions as the electromagnet?

[@seigiyokota6910]

mcnimi the copper spiral

[@coondogtheman]

Can you please tell us about that chip playing the music. Do you have a video on it?

[@zer0b0t]

lm386 should do it

[@Baccolo100]

genius!!

[@douro20]

What was the driving voltage?

[@abpccpba]

Thank You so much for you intriguing experiment.

[@LHUPA]

@TheNikko242 There is a song by The Turtles titled "Happy Together" a song released in 1967!

[@fhs_darius953]

Can u use a really strongh magnet then u will se some magic

[@eVITORIOe]

so far the best...

[@kencochi]

can i use foil??

[@MaBuSt]

love it

[@sonjafruk8341]

Thank you!!!

[@TheNikko242]

song please RESPOND PLEASE

[@BugBassShigu]

song ？

[@coondogtheman]

The smaller ones seem to be louder.

[@jinx4767]

Depends upon the size and power of the magnet. The small coil worked well with a small magnet

[@amyjor303]

OMMMMMGGGG

[@southparkvspeace]

Before lg

[@hr1100]

Spooky

[@GraemeWolfendale]

too^

[@GraemeWolfendale]

This shouldn't really work, copper isn't magnetic.. Very nice anyways.

[@miguelchacon2717]

Your dumb as you look like
