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 :)
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.
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.
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!
I love youtube for this kind of stuff. Great vid, very educational ::D I know how speakers work but things like this really make you think out of the box.
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 !
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?
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.
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 ?
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.
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 :)
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?
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.
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!
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".
Iteresting how different materials and patterns does respond differently. Cool tho, now I know how to make my very own speaker on a deserted island. XD
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!!!
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.
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...
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.
U made mistake on gold leaf version. MUST be leaf on BOTH sides. Also...remove your hand from the equation/magnetic field. Place magnet on wood surface. Neat video!!!
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...
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.
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.
I try to make this ink a lot of kinds of glue but I see that it can not make electricially conductive. I've used silver and activated carbon. So please tell me how can you achive this conductivitiy via glue?
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.
get rid of the permanent magnet and drive split phase. interleave the coils on forward and reverse sides with opposing phase causing the paper to flex on its own,
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.

es un sintonizador de radio conectado a un transistor que funciona como modulo amplificador y es alimentado con una batería, es un circuito sencillo de electrónica básica y lo de el parlante es aun mas sencillo
@thegizmoguy1 Thank you very much... I will try a flexible material like a thin plastic. But here at the shop,I have flexible unetched PCB for special applications and I will try too!...
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.
I think the magnetic flux has the wrong direction. To operate the coil in the right flux direction you need radial flux. In order to get it you can align 2 magnet disks on axis in repulsion. The magnetic flux will then be squeezed radially out of the gap. But it returns after a short distance to the back sides of the magnet disks. This means you have to prepare as many windings as close as possible around the gap. I guess, for a pair of magnet disks with a diameter of 10 mm you can get from 10 to 20 mm diameter with your spiral coil. I could simulate the magnet system and the coil with FEMM in order to look for the maximum coil diameter you can effectively use. If you like you can respond to get a design suggestion. I think you can use double sided copper coated flexible pcb material to prepare 2 spiral coils by toner transfer or photo resist lithography and etching.
it might work better if you didn't touch the paper since speakers work on vibrations there for your touching it just decreases volume and distorts the souund (the same goes for the alligator clips
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

PPanos1968 im not sure if u actually no your shit or if u just up a whole buch of fuckig words
Thats it, Im making a 2000 watt paper plate subwoofer for my home theater
2000w plus paper speaker is how you make fire not sound.
Wuety06 I suppose it'd make a nice crackling sound ;-)
Hey now, Say im watching a campfire movie.........crackle crackle.....
Now I know how beats are made.
LOL
If there's no highs an lows, it's gotta be Bose... no mids and tweets, it gotta be Beats
lol, they should get together and make Bo-ats.

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
Do you mind? I was listening to that! Quit pulling the magnet away from there!
:D
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!
That's better than my phone's speaker! And this is made of friggin paper!
Seconded!
So true!
I sounds kinda like something taken out of a fallout game... I love it
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!
I see you bought a pair of Beats.

Its Better Quality too
What kind of dark witchcraft is this?
Did the "coils" really work as speakers?
it'd be fucking more effective to use two coils with inversed polarities one in witch side of the paper.
noooo!!! is the power of god
This is a very simple form of a rodin coil speaker, those kinds of speakers are incredible they can produce 3D sound
Shannon Williams
Thanks for the name of the speaker!
Wikipedia calls it Bifilar coil, link here:
en.wikipedia.org/wiki/Bifilar_coil
Yes. Easily replicable!
This was a ancient method used by the Egyptians to Listen to da RADIO
If only radiowaves could travel through time lol
Joey Gareau if only you had not posted your opinion
Sorry ;_;

Thats magic ! Black magic ! !
This is so interesting that even after 11 years I'm interested in trying this
"Because we can". Great experiment, copper wins, and more windings may help.
To think what we can make now at home; because of our knowledge.

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

This is very simple and well made.
Happy Together... a beautiful song
However, very good work.
try a bigger magnet. and try to make the paper round
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.
***** of course they do! they flex in a different manner!
Not a noticeable difference at this scale and at those frequency's. This isn't a subwoofer.
Interesting to try that magnet on a larger metal disc to see if it increases volume
U made mistake on gold leaf version. MUST be leaf on BOTH sides. Also...remove your hand from the equation/magnetic field. Place magnet on wood surface. Neat video!!!
It's like saying "There needs to be a morale in every single story"
Wow high fidelity if ever I've heard it.

Great scene. I never was so hi-i-i-igh!

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!
And this STILL sounds better than Bose!

Take a very thin enameled wire and wind a flat coil with a resistance of 8-16 ohms. The sound will be awesome.
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
sounds like those old time radiosssssss!!!! lol
Прикольно,теперь понятно каждому,как работает динамик!

Dude you are a genius

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

does it work with toilet paper? or with 100 $ papernote?
work sure, with used one too ;-)
Maybe you should try a bifilar winding as Tesla's pancake transformer, as the bifilar winding increases the magnetic field :)
I wonder how it produce any sound at all. Because the coil circuit of speaker is not complete.
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.
