@AflacMan13 it does.. when I go up with the input voltage too much.. the problem then is the top capacitor plate.. it is made of a circuit board and not of copper or aluminum at the moment.. so it burns....
So what's the limit on the power output to the corona? Where does the most dissipation and temperature rise happen?
You don't say so explicitly, but I'm assuming you're modulating the duty cycle of the gate pulses to get audio. Have you considered using drain voltage modulation? Should give lower distortion and better efficiency.
I've been considering building a plasma speaker in the 1-2KW range, and yours is the closest I've seen to that. Great work so far.
@lolly83 I thought it could only play midi files? or at most music only, but being able to form words too? That's amazing! You should sell that design to the guys who make the bigger ones and perform with them
how the fuck can this play drums and stuff? i mean i know it emits sound waves in different frequencies like speakers, but for drums (not really base) how does it do it? i thought it couldn't do teh frequency of drums?
You did a really good job, I like the sound profile from what I can hear, and I think you stumbled onto the key of getting rid of the distortion, it's the spread of the arc, Tesla would be proud of you.
Question: i hear that rounded surfaces collect charge better..... from videos i have seen the plasma sparks look longer with a rounded toroid? have you tried this, if so how did it compare. what are your thoughts and opinions?
Does the volume scale with the size of the tesla coil? As in, would it be theoretically possible for someone to make a few massive coils to use as amps for a full on rock concert?
@chaosfood yeah in fact it does.. I am testing my large coil at the moment and it is too loud to be near it too long. the problem is that with bigger size the resonance frequency becomes lower so it is not possible to use it as a speaker any more. the bigger coils are more like an instrument where you can play single( or with tricks also more) distinct notes. I made me a converter from MIDI format to my Tesla controller :-)
It works very well. there will be another video about that soon.
@lolly83 Just to clarify, because this is totally awesome and I immediately shared chaosfood's curiosity, why would lower resonance frequency lead to larger coils being unsuitable as speakers? If you can answer this, is there any way you could dumb your answer down? I can use large math terms, but physics terms are a different language indeed.
@mtb4u Thanks for your comment. It's the other way round: Large coils lead to lower resonance frequencies. If you assume that the Quality factor Q stays constant that immediately leads to a longer response time of the coil. in effect the coil starts to "average" your input signal and it can't follow all the higher frequencies you want to play. Lower (bass) frequencies might still work. I have one event next week where I'll show the coil. After that I can test that more, because I might break it.
@lightingrings hi.. it's quite simple. basically it is controlled thunder. When the air is heated it expands. When it cools down it contracts. In a plasma speaker you control the temperature of the flame by modulating the power which is going into it. So you change the temperature of the flame with the frequency of the sound and the air starts to vibrate like being pushed by the membrane of a speaker.
Right, sorry, i'm a bit dense when it comes to this... I've read the description and it seems to say the sound is coming from the actual plasma that's being generated.....is that correct??
can someone give me schematics of how to build one. i want to have these speakers for my wedding my wife to be would love this for our wedding it would also be very cool for my guests to see. i want to build 4
@brandonhughes7 in the normal audio modulated mode there's about 400W of power in the flame. You won't get electocuted but the flame is extremely hot. In pulse mode it's fun to play with the arcs :-)
I had been looking into this and found a man named Dr. Patrick Flanagan who developed the "neuro phone" back in 1958. It's exactly this idea, but he already did it!
Which means I'm right! Awesome.
I also had the idea of connecting a real time language translator to it so someone can speak chinese and you would hear English in your head.
But his patent got seized by the NSA and never got to release it.

could you play classical music on there? i wonder what the quality would be like. i also wonder how well the camera you used recorded the sound.. it looks stunning, and if it sounds as good as it looks, huge props.
I have a question for you about your setup : is the 1mhz the resonnance frequency of the coil or the PWM frequency of your audio signal? It's just a detail but if i could now it ;-) I am building a compacted flyback audio driver with some components of an old endoscopic light and a broken PC monitor,and I would test the magnifier of Nikola Tesla on a plasma speaker!... ^^ broken for broken... :p
@jimmy69neutron69 Hi Fernando, thanks for your comment :-) The 1 MHz is the resonance frequency of the coil. The PWM-Frequency is just around 50kHz but this low frequency is possibly one cause of noise coming out of the flame. I wish you good luck and much fun in recycling your trash ;-) its quite worth it!
@lolly83 Sorry Lolly, but when I see your oscilloscope, it seem that a carrier frequency is pulse-width modulated with about 20 pulses for a period. Am I wrong or not? Anyway, that's a great result!! When we ear clearly the noise at the end of your video, it remember me a problem I had with the power supply of my notebook. Noise of audio output was high when I was connected to the earth with my notebook, so I changed my power cable for a class 2(no earth), that resolved the issue. Bye!
@metrev117 you're welcome ;-) unsafe? only a bit.. the plasma flame itself is only very hot. it will burn your skin like any other flame. you won't get electrocuted when you touch it. In fact when I set the coil on short pulse mode it is not a problem to touch the arcs. The most dangerous thing is the 120V DC going into the generator. These parts are inside a box and cannot be touched when it is closed.
@davidt2468 You can achieve bass response only with a larger plasma flame because you need to move more air. The energy consumption would be a bit off the scale though.
Ich muss schon sagen, die Apparatur sieht sehr beeindruckend aus und der "singende Blitz" im Dunkeln ist einfach nur schön. Ist das Ganze dann auch so stromhungrig wie es aussieht? Von dem satten klang bei höherer Lautstärke bin ich überrascht, ich dachte es bleibt bei dem Krächzen direkt nach dem Einschalten.
@Dittersch Dankeschön! Naja so im Mittel braucht das ding so 300-400W aus dem Netzteil... bei 4:10 ist das auch kurz sichtbar... ist also noch Vertretbar ;-)
@chayes2007 An RF field with a frequency of abt. 1MHz is generating the plasma. With such an RF field the inertia of the atom cores is so large that only the electrons will be moving to and away from the electrode. The space of the surrounding air is enough to give the moving electrons the room for the movement. There is only a "target" of the arc if an metal part is quite near to the electrode.
Excellent! Historically, the 1st "hint" at this sort of phenomena can be found in Exodus 3:2 --the mystery solved when you realize that the "fire" was a modulated electrical plasma. A similar (much larger scale) account can be found in Revelation 10:3 --modulated lightning (7 thunders) to speak. Considering these accounts were written +4000 and +2000 years ago (respectively) gives insights (at least to anyone with an ear to hear) about the nature of the Designer.
Warum wird der Lichtbogen zwischen den zwei Liedern eigentlich nicht kleiner? Sollte er in einer Ruhephase eogentlich nicht ganz verschwinden und nicht weiter brizzeln?
Why does the light ark not vaniish between the different tracks?
@Glaswalker1001 das liegt daran, dass bei "Stille" die Flammengröße quasi in Mittelstellung ist also 50% ihrer Maximalgröße hat. Ein Lautsprecher bewegt sich ja auch nicht nur nach aussen sondern auch nach innen. Wenn man bei Stille die Flamme abschaltet wird nur eine Halbwelle des Signals ausgegeben. Den Effekt hört man bei den Coils von der Geek Group oder auch Scopeboy. Das ist zwar als Effekt für ne Gitarre ganz nett, hört sich aber bei normaler Musik furchtbar an.
@xLUXnXax danke :-) bis das Ding zum ersten Mal Musik gespielt hat (nicht die "Upgraded"-Version) hab ich zwei Monate gebraucht, wobei einer davon die Zeit zwischen Praktikum und Diplomarbeit war und ich somit "Vollzeit" daran arbeiten konnte. Der Upgrade ging gann irgendwann in den nächsten Monaten. Aber so ein Projekt ist ja nie 100% abgeschlossen.. Es gibt immer was zu basteln :-)
@cr99991 no I don't modulate the DC supply. I want to do that in the future as I hope the sound quality will get better but at the moment I am modulating the Control Signal of the Power Transistor. The PWM is going into an AND-Gate with the resonance frequency of the coil at the other input. The output is directly going to the Mosfet driver and the Coil itself acts as a low pass filter. So you don't need any more power electronics than without modulation and it's easy to implement.
yes it does. It uses an mixture of gases which contains approx. 78% nitrogen, 21% oxygen and 0.93% argon (aka. earth's atmosphere). Ionization only means that some/all the electrons of the gas atoms are seperated from the atom cores. This is done here by an large electromagnetic field with a frequency of abt. 1MHz.
Dude that is badass, my Tesla Coil isn't that cool sadly. But I did manage to find a way to give my Tesla Coil an EMP-like factor that disrupts electronics fairly well (Sometimes short-circuits stuff too).
sure I can do that :-) It is basically controlled thunder. The plasma flame is very hot and changes its temperature with the size and the energy going into it. Hot air is expanding and cold air is shrinking. The energy going into the flame is controlled and modulated according to the audio signal so that the air vibrates like a membrane of a speaker. That's it ;-)
Wow, that was really fast, short and easy to understand.
THank you very much :).
As i said, never heard about it but they exist since 1970s o.o.
IS your tessla really dangerous(when touching)? I think thats one bad thing about the. Isnt there a possibility to put them in a plastic tube maybe?(like the magic plasma ball or how its called in english)
I have a plastic tube for my tiny tesla coil.. but when it's on the coil it sounds like being in a bathroom. It's not more dangerous to touch the arcs than to touch a candle-flame. you don't get electrocuted because the high frequency current is converted to heat directly on the surface of the skin. you get bad burns from it though...
I was wondering if it is possible to extract different frequencies by using different gauge chicken wire? Sounds a little flat as is but good job man.
Also wenn ein Funkamateur einen Lautsprecher baut der gleichzeitig ne prima HF-Schleuder ist, ist das die perfekte Fusion von zwei Hobbys. Hut ab und weiterhin viel Erfolg und Spass dabei!
I am an electrical engineer graduate from america. I am so very impressed with your skills in creating this. How did you design this device? Would you allow someone to duplicate your device?
mhm I think neither will happen. Plasma speakers are something for the real audiophile
people wanting the best audio experience possible. The problem with this type of speaker is the very low efficiency. This single particular speaker takes more than 300W continuous power.. another problem is that they produce some ozone which can be smelled at very low concentrations.
leider nichts, was man so ohne weiteres kaufen kann.. und (wegen des preises) will man das wahrscheinlich auch nicht.. Ich verwende den DRF1200 bzw DRF1201 von Microsemi. Das ist ein integriertes Modul mit Treiber und MOSFET (1000V 13A respektive 28A) und ist eigentlich für industrielle HF-Anwendungen bis 30MHz gemacht.
Excellent

Combine this concept with an electric muscle stimulator.
Deaf people can't hear but they can still feel a shock.
If you modulate the shock so that it has music the person will hear it.
It would only take very little power to achieve enough vibration for the person to hear the frequencies throughout the body.
When you get tazed, you hear a loud zaapp in your head. If you modulated that frequency you could hear music.
Modulate a microphone to convert audio to electric signal and the deaf can hear.

With such an RF field the inertia of the atom cores is so large that only the electrons will be moving to and away from the electrode. The space of the surrounding air is enough to give the moving electrons the room for the movement. There is only a "target" of the arc if an metal part is quite near to the electrode.

Excellent! Historically, the 1st "hint" at this sort of phenomena can be found in Exodus 3:2 --the mystery solved when you realize that the "fire" was a modulated electrical plasma. A similar (much larger scale) account can be found in Revelation 10:3 --modulated lightning (7 thunders) to speak. Considering these accounts were written +4000 and +2000 years ago (respectively) gives insights (at least to anyone with an ear to hear) about the nature of the Designer.

Warum wird der Lichtbogen zwischen den zwei Liedern eigentlich nicht kleiner? Sollte er in einer Ruhephase eogentlich nicht ganz verschwinden und nicht weiter brizzeln?
Why does the light ark not vaniish between the different tracks?
Glaswalker1001 1 year ago
@Glaswalker1001 das liegt daran, dass bei "Stille" die Flammengröße quasi in Mittelstellung ist also 50% ihrer Maximalgröße hat. Ein Lautsprecher bewegt sich ja auch nicht nur nach aussen sondern auch nach innen. Wenn man bei Stille die Flamme abschaltet wird nur eine Halbwelle des Signals ausgegeben. Den Effekt hört man bei den Coils von der Geek Group oder auch Scopeboy. Das ist zwar als Effekt für ne Gitarre ganz nett, hört sich aber bei normaler Musik furchtbar an.

Wow gratuliere!!
wie lange hast du für das ganz gebraucht?
xLUXnXax 1 year ago
@xLUXnXax danke :-) bis das Ding zum ersten Mal Musik gespielt hat (nicht die "Upgraded"-Version) hab ich zwei Monate gebraucht, wobei einer davon die Zeit zwischen Praktikum und Diplomarbeit war und ich somit "Vollzeit" daran arbeiten konnte. Der Upgrade ging gann irgendwann in den nächsten Monaten. Aber so ein Projekt ist ja nie 100% abgeschlossen.. Es gibt immer was zu basteln :-)

Do you modulate the DC bus voltage? If so how? Do you use PWM through a low pass filter?
cr99991 1 year ago
@cr99991 no I don't modulate the DC supply. I want to do that in the future as I hope the sound quality will get better but at the moment I am modulating the Control Signal of the Power Transistor. The PWM is going into an AND-Gate with the resonance frequency of the coil at the other input. The output is directly going to the Mosfet driver and the Coil itself acts as a low pass filter. So you don't need any more power electronics than without modulation and it's easy to implement.

You are awesome! nice setup. I hope you have a job in the electronics field!
cr99991 1 year ago
@cr99991 thanks :-) I am doing RF power generators for plasma and CO2-laser applications. So I had some experience with that kind of electronics.

Doesn't a plasma speaker use Gas or ion?
Sveken 1 year ago
yes it does. It uses an mixture of gases which contains approx. 78% nitrogen, 21% oxygen and 0.93% argon (aka. earth's atmosphere). Ionization only means that some/all the electrons of the gas atoms are seperated from the atom cores. This is done here by an large electromagnetic field with a frequency of abt. 1MHz.

Have you ever considered adding an equalizer to the gate of the MOSFET?
bauditlad 1 year ago
Dude that is badass, my Tesla Coil isn't that cool sadly. But I did manage to find a way to give my Tesla Coil an EMP-like factor that disrupts electronics fairly well (Sometimes short-circuits stuff too).

Never heard about this and iam really surprised. didnt know that this is possible. MAybe someone could explain it a bit more in detail?
Sebal007 1 year ago
sure I can do that :-) It is basically controlled thunder. The plasma flame is very hot and changes its temperature with the size and the energy going into it. Hot air is expanding and cold air is shrinking. The energy going into the flame is controlled and modulated according to the audio signal so that the air vibrates like a membrane of a speaker. That's it ;-)
lolly83 1 year ago
Wow, that was really fast, short and easy to understand.
THank you very much :).
As i said, never heard about it but they exist since 1970s o.o.
IS your tessla really dangerous(when touching)? I think thats one bad thing about the. Isnt there a possibility to put them in a plastic tube maybe?(like the magic plasma ball or how its called in english)
Sebal007 1 year ago
I have a plastic tube for my tiny tesla coil.. but when it's on the coil it sounds like being in a bathroom. It's not more dangerous to touch the arcs than to touch a candle-flame. you don't get electrocuted because the high frequency current is converted to heat directly on the surface of the skin. you get bad burns from it though...

I was wondering if it is possible to extract different frequencies by using different gauge chicken wire? Sounds a little flat as is but good job man.

Hiddenjello 10 months ago
@Hiddenjello No the chicken wire around the coil acts as a Faraday cage and absorbs the magnetic field.

Do you think plasma speakers could end up rivaling the basic magnet/air pressure style speakers, or are they strictly science fun?
ShesAHoFoShoYo 2 years ago
mhm I think neither will happen. Plasma speakers are something for the real audiophile
people wanting the best audio experience possible. The problem with this type of speaker is the very low efficiency. This single particular speaker takes more than 300W continuous power.. another problem is that they produce some ozone which can be smelled at very low concentrations.

Welchen Mosfet und was fürn Mosfetdriver benutzt du?
TheMowFlow 2 years ago
leider nichts, was man so ohne weiteres kaufen kann.. und (wegen des preises) will man das wahrscheinlich auch nicht.. Ich verwende den DRF1200 bzw DRF1201 von Microsemi. Das ist ein integriertes Modul mit Treiber und MOSFET (1000V 13A respektive 28A) und ist eigentlich für industrielle HF-Anwendungen bis 30MHz gemacht.
