Paper Speakers (various materials)

[@PPanos1968]

My dear friend, I am so happy there are still young people out there trying to figure out how stuff works and making home experiments. To help you, I am sure that your main mistake is the missing biasing of the TIP122 transistor. You drive the transistor either lower or above its linear working point. The result is low efficiency and high distortion. To control the biasing, use a potentiometer (or a simple trimmer resistor) around 10KiloOhms, connect the two ends with + and - of your power source, connect the middle leg with the transistor's base, and use a capacitor between the base and radio output. A few microfarads should be enough. The capacitor allows the biasing voltage to be different than the radio output voltage, while sound goes thru it. Start by setting the potentiometer in the middle point and then listen to the sound while rotating the potentiometer to the - power pin (not to + since this could burn out the TIP122). You should find the perfect spot and your paper speaker may sound much better. Good luck and give me feedback :)

PPanos1968 im not sure if u actually no your shit or if u just up a whole buch of fuckig words

[@davidburke4101]

Now I know how beats are made.

[@Videocrazymachine]

LOL

[@Wuety06]

If there's no highs an lows, it's gotta be Bose... no mids and tweets, it gotta be Beats

[@654597601]

lol, they should get together and make Bo-ats.

[@Individuality1990]

Wuety06 what,

[@JDTVEXTREMEVIDEOS]

Thats it, Im making a 2000 watt paper plate subwoofer for my home theater

[@Wuety06]

2000w plus paper speaker is how you make fire not sound.

[@matthehat]

Wuety06 I suppose it'd make a nice crackling sound ;-)

[@JDTVEXTREMEVIDEOS]

Hey now, Say im watching a campfire movie.........crackle crackle.....

[@AdvaitThakur]

The presentation of this video is as simple and best as the innovation. Paper speaker, very simple and unique innovation. I like the idea of showing slides of text. Sometimes simple methods, ideas present great innovations.

[@HapplyFace]

sounds like beats

[@thelion.4K]

+HapplyFace you sir won it.

[@ShortStorytime]

Do you mind? I was listening to that! Quit pulling the magnet away from there!

[@Tutterzoid]

:D

[@egyember4981]

Sounds like a 50's radio :D

[@realgroovy24]

The speakers in a lot of older radios are actually much better than you think, I've got some which kick the crap out of a lot of modern speakers, although depends if it is high end or low end, also whether it is a portable or tabletop or console radio.

[@UnremarkableMarx]

Made in America speakers were always quite fine, for todays standards. But obviously the lo fi ness and warmth is evocative of old radio for sure

[@Nor9864]

That's better than my phone's speaker! And this is made of friggin paper!

[@zhiracs]

Seconded!

[@debug9424]

So true!

[@elnovatodelaweb]

I sounds kinda like something taken out of a fallout game... I love it

[@UZI9MMAUTO]

In the army they made speakers and powered them with N O electricity. They made them to hear their foxhole radios. I just LOVE electronics!

[@CaseyLotto]

Nice simple design, makes it easy to test many more materials which I hope to see done soon, thanks.

[@RuiSilvaPT]

very nice, it's the basic principle of a speaker a coil and a magnet, very cool indeed! Thumbs up!

[@KianGurney]

I see you bought a pair of Beats.

Its Better Quality too

[@sebbes333]

What kind of dark witchcraft is this? Did the "coils" really work as speakers?

[@fss1704]

it'd be fucking more effective to use two coils with inversed polarities one in witch side of the paper.

[@rapazitul]

noooo!!! is the power of god

[@blistex239]

This is a very simple form of a rodin coil speaker, those kinds of speakers are incredible they can produce 3D sound

[@sebbes333]

Shannon Williams Thanks for the name of the speaker! Wikipedia calls it Bifilar coil, link here: en.wikipedia.org/wiki/Bifilar_coil

[@DirkIronside]

Yes. Easily replicable!

[@compagucky7609]

This was a ancient method used by the Egyptians to Listen to da RADIO

[@godjoey1]

If only radiowaves could travel through time lol

[@rapazitul]

Joey Gareau if only you had not posted your opinion

[@godjoey1]

Sorry ;_;

[@godjoey1]

Lol I'm good I was just kidding XD

[@santiagofernanda1062]

No, to spotify

[@MikeGervasi]

"Because we can". Great experiment, copper wins, and more windings may help.

[@mattmoreira210]

Interestingly enought, such a simple thing can work so well... it's impressive!

[@MilanKarakas]

If you are able to put conductor on the clothing I think this will give you the best result. Also, use smaller coil in diameter, and stronger magnet - to cover whole coil. Excellent experiment!

[@MaximumBan]

Fantastic demonstration of magic! :-)

[@incredibler2]

This looks incredible. Could you please explain how you made the circuitry?

[@انا_ابراهيم_البناوي]

This is so interesting that even after 11 years I'm interested in trying this

[@TheTechAdmin]

To think what we can make now at home; because of our knowledge. One day we'll be making miniature time machines out of 2 lightbulbs, 3 magnets, tin foil and a microwave !

[@Bunglay]

i cried this is amazing! I'm gonna invent something great one day!

[@LHUPA]

Genius! I will try this with thin PCB! So, I have both copper faced semi flexible PCB board unetched and I will etch a coil each side and try it to build a sturdier version of that paper speaker! I notice that the coil works like a piezzo speaker! If it works, I will show it to you!

[@FelipeL67]

very clever design, it is very unique

[@zxcv1234vcxz]

Oh, man, are classic songs that unknown to the younger generation? ^_^ The song is "Happy Together", by The Turtles, from 1967.

[@bartoszbarejko1585]

This is very simple and well made.

[@TheDocOliver]

Happy Together... a beautiful song However, very good work.

[@Pulverrostmannen]

the current trough the wire creates a magnetic field that reacts to the permanent magnet and makes the paper vibrate. this is pretty much how a real speaker works showed in the basics :) it's a nice way he show it in the video :)

[@slavric]

Hi. This works exactly on the same principle as all EM loudspeakers do. But in ordinary speaker the coil is wound from a thin wire on a coil. The coil is place in a gap of a strong magnetic field. Since the current from the output device generates the current in audio frequencies. That current creates another magnetic field which repells or atracts the coil. This changing creates the force in a coil which moves the membrane it is attached to and the membrane moves the air and creates the sound.

[@hili467]

interesting. could you explain how/ why it works this way? I get the coil, magnet, diaphragm part of it, that's typical of a conventional speaker. One of the parts I don't understand is the front and rear coil bit, is there a hole in the paper where the innermost parts of the coils can touch and complete the circuit?

[@s35]

Cool Video to understand how a speaker simply works.

[@AshishRrr]

Cooooool...👍👍👍👍👍👍👍 Very interesting 👍👍👍

[@mrfudd13]

Very interesting video; I don't understand why copper tape would react to a magnet. Thank you, thank you, thank you: for not adding background "music".

[@TheJoshinator1]

Electromagnetic induction. The electricity in the audio signal going through the copper makes a small magnetic field that vibrates with the music. It reacts to the magnet he's holding, and since the copper's attached to the paper it vibrates the paper to create sound waves. Pretty cool, huh?

[@Razzics]

Is that a less sophisticated version of what's happening in my KRK Rokits? If not, that's still pretty nifty.

[@benbenekben]

Thats magic ! Black magic ! !

[@pasteawey]

I just shat myself. I like the authentic Sound effect it has

[@izawha]

Where does one get copper tape? I wonder if copper wire would suffice... Also, neat discovery I made a long time ago; those tiny DC motors work as speakers. This would make sense, seeing as they contain magnets and copper coils.

[@Savagetechdude]

The sound quality is amazing!

[@MauroTamm]

close - most common speakers use a coil (electromagnet) around a permanent magnet to create movement. Just get one of the small magnets, wrap paper strip around it and then insulated wire (thin) bunch of times. And glue some kind of membrane on top to amplifiy. And you have a low quality speaker. Alternatively there are also electrostatic speakers.

[@DUKeGGable]

Круто! Завтра делаю себе бумажный саб!

[@thBibas]

still better than beats

[@mehdiSupp]

Sound is basically vibrations right. So if you're touching the paper you're blocking or at least altering these vibrations. Can you explain how this works ?

[@daniilgentili5043]

My guess is that he is certainly blocking some of the vibrations by touching the paper but the remaining area of the paper is big enough to distribute the remaining vibrations in the air.

[@das250250]

Interesting to try that magnet on a larger metal disc to see if it increases volume

[@RCAvhstape]

MacGyver speakers

[@michaeljay4261]

That'd make sense. Coils in speakers are far more efficient, so the signal going into this one would have to be stronger to be that loud.

[@protonspeed]

great method of presentation , but how you have made copper stripes on paper .?

[@homerelesperance2857]

Wow, that's amazing! 8)

[@SoulTouchMusic93]

try a bigger magnet. and try to make the paper round

[@Pigeoncraft]

at that scale it doesn't matter if there is a bigger magnet then that and also at that scale it doesn't matter if the paper is round. And round speakers don't sound any different then square ones at this scale.

[@SoulTouchMusic93]

***** of course they do! they flex in a different manner!

[@Pigeoncraft]

Not a noticeable difference at this scale and at those frequency's. This isn't a subwoofer.

[@johnny1upz]

Yes your are correct, they are both then same thing but in reverse. You can use an old speaker in a box if done properly as a mic. The more you know!!!

[@nomokvil2044]

Amazing & creative! :)

[@r0zz05]

Oooo! Now I know why there are magnets in my earphones! :D I've always wondered about that

[@2222person2222]

It's like saying "There needs to be a morale in every single story"

[@gabor12800]

Cool. Please make a 5.1 system with those!

[@coondogtheman]

I figured that but it looks like he took a stock chip and added a transistor to make it louder. These chips have enough power in the chip's built-in amp to drive a loudspeaker but it looks like he added that transistor to make it much louder, or that chip doesn't have an amp built-into it.

[@x_JUSTxSENDxIT_x]

I will stick with my sundowns thank you though, great video

[@irealydontcare7836]

You have never seen a polypropylene speaker? It's a very common material to make the cones for car speakers out of these days. Also, many tweeters are made out of non-paper materials such as silk or aluminum. The only home theater speaker company that still sells paper speakers as "high quality speakers" that I can think of is Bose, and they don't even sound that great.

[@troysanders7775]

Wow high fidelity if ever I've heard it.

[@Labr4tOfficial]

You my friend, are simply amazing!

[@Gigaguenther]

don't get me wrong, these are really nifty, but "paper speakers (various materials)" - that just cracks me up xDD

[@XandrGlad]

Прикольно,теперь понятно каждому,как работает динамик!

[@zigaudrey]

The sound is weak but it is a great work!I love the spiral on the paper. With two of them,you can make a headphone!

[@anujpj]

i guess you need a bigger magnet, and add more loops to the coil this time much tighter (closer)

[@richdelgado3405]

And this STILL sounds better than Bose!

[@sethery7826]

Really good but does it work with tin foil?

[@Anachronos1]

Nice, you found hot water..............again. :)

[@jobobakodis]

imma be the next best selling speaker company. watch out bose.

[@patrickdonnelly9386]

This is awesome! What is the ideal distance?

[@coondogtheman]

Can you please do a video on how you made that board that plays the music?

[@TehBPG]

Dude you are a genius

[@Elec-DIY]

A great idea, liking

[@MrClassicDoctorWho]

with the state of the economy throughout the world at the moment, this might actually be a viable option for cheap entertainment equipment! xD

[@FrankLopezx]

i wonder if this conductive tape would be good for high current but not in the 15amps just mid i guess? or even if is resistive on the ohm meter

[@weaselsuit]

Sounds better than some Behringer products!

[@WeebLabs]

This is not the point which nala243 was attempting to make, however "better" is a subjective matter. He is correct in that sense. Although it is certainly true that there are headphones which provide a broader frequency response and less distortion than Dr. Dre headphones at a much lower price, the matter of whether they are "better" can not be measured objectively.

[@flamencoful]

I love being an electronical engineer.

[@utkua]

i wonder if it is possible to make a speaker without magnets, using 2 pieces flat inductor paper like yours, and facing them together with a small distance, so they can both push and pull each other, i guess there may be a simple electrnics requirement which may be used to make flow one direction on one of them, so they can push each other when the same direction if flow is and pull vice versa... anways. it is late here

[@hoppopandaciddrop]

I have been sad until this night. I will see my Sandy! Alri-i-ight! Great scene. I never was so hi-i-i-igh! Maybe she is not bubble what I want to li-i-ight...

[@ВасилийТёркин-г3м]

Take a very thin enameled wire and wind a flat coil with a resistance of 8-16 ohms. The sound will be awesome.

[@vikashkotteeswaran700]

this is awesome ! and great can u upload a video of doing a laser cutter ?

[@2right4words]

I used to work for a company that made specialty items for the government, if you know what I mean. In the lobby they had this beautiful piece of wound copper, which was sitting under the desk, made to look like artwork, but I knew right off the bat it was an antenna...

[@analogplanet9675]

1000% thd 😂 but seriously, nice work on these, thanks for sharing them!

[@TheN4UM4N]

Cool! What's the name of that first song he did?

[@ColeAlexanderSoftware]

This is aweome. AWEOOOOOMMMMME

[@Masterkodak]

Maybe if you made the coils smaller you could get better audio quality? Keep up the good work!

[@lightningstrike20111]

Surely you need to mount the backing of them in a rigid frame

[@pmgodfrey]

That's incredibly cool -- but the quality reminds me of half the music here on KZbin because people don't know what rates to encode them at.

[@cirofusco3572]

Complimenti! Come hai avuto l'idea?La spirale ci segue ovunque e nasconde in se il mistero stesso della vita.

[@himanshudarfade]

Can you please share the full circuit? and where is that song coming from ?

[@mattmoreira210]

Nice, bro! Thnx for posting it.

[@coondogtheman]

Nice song, What chip is that?

[@MrGoatflakes]

How come the gold ones suck so bad? Lower conductivity of gold versus Copper?

[@SeniorSupersuade]

The gold leaf paper experiment was made with the signal generator powered off.

[@MrFavorite01]

I'm sure if you can make more rings on there, you can make better sound quality, as the magnet will have more electrolyzed metal to influence.

[@blindlight]

how do you get the tape to curve so well?

[@dlwatib]

The most conductive metal is pure silver. Copper is second most conductive. Gold and steel are less conductive that pure copper. Also, the gold leaf probably wasn't pure gold, so it was an alloy of gold and some other less conductive metal than copper. Aluminum is less conductive than pure gold, but probably more conductive than your gold leaf sample. I would try silver foil/leaf and materials more compliant than paper. Rice paper is thinner. That might work better. Teflon might be good. Saran wrap would be interesting. Real speakers use plastics like aramid and kevlar. Also, experiment with stronger magnets.

[@Tutterzoid]

Maybe you should try a bifilar winding as Tesla's pancake transformer, as the bifilar winding increases the magnetic field :)

[@Spacekriek]

At least sounds better than the garbage some modern pop stars spout...

[@TheTechAdmin]

What I'm saying is, now, with the knowledge, we can make it at home with common items. But it wasn't always that way. Yes, we may have had the items to create, but at the time, didn't know it. So right now, in your home, you HAVE the things to make a time machine ( radical example ), but you just don't know what's needed, the order, etc... But, it's all there, right now.
