Plasma speaker "Hi-Fi"

This is the result of my latest experimentation, a high-quality low distortion transformer plasma arc speaker ("singing arc"). A PWM audio modulation circuit (TL494) runs at 40kHz, drives two mosfets in phase in a "half-controlled fullbridge" fashion (two switch single pulse forward-flyback converter). A RC damping network on the primary gets rid of unwanted oscillations during the free-wheeling phase.
As always, the camera distorts the sound a bit and cuts treble, it sounds cleaner in real life.

first what is the name of the song

second whats the scehmatic, you website doesn't work i even removed the spaces, its says renamed or removed in czech

[jmartis2]

@ubuntupokemoninc The song is Pure Moods by Yanni... I PM-ed you the website.

[KnoxaramaV2]

there isn't anything that can be taken apart to get a tl494 is there?

or at least another chip that can be used to replace it?

[jmartis2]

@KnoxaramaV2 you can find TL494 or its clones in PC power supplies.

very good quality of audio signal, can i have the schematics please ? thank's

[jmartis2]

@darkeagle512 here is my plasma speaker page, hope you can at least read the schematics as I'm too lazy to translate it into english... :D

finally youtube will let me post the website: hvlabs. com/ plasmasonic. html (remove spaces) and the actual schematic:  hvlabs. com/Images /plasmasonic .JPG (remove spaces)

Good job.

[TechKidusa]

sorry for no link youtube will not let me type in the website without making me deleat it, so if you want the schematic for this just send me a message. :)

[TechKidusa]

Here is a link to the schematic ( in english)

[HighVoltageProjects]

hi this is great could you send me a schematic please or a link where i could find it ,also do you think this could run a sstc or even better a bipolar tesla ,im thinking biplar would give a better qualitty as it would have a gap like with the flyback that you use, rather than open air .thanks John

[OverlyExcitedNewJack]

this is excellent. would you say a plasma speaker can be used as a center channel in audio? Is the range good enough? can you get a solid clean 20khz freq response on this cocksucker? thanks

[JosephCreeper]

That's fuc*** awesome! schematic please! =D

[CornetHornet]

This is fantastic! Great job. Could you send me the schematic please?

[billysgeo]

@jimmy69neutron69 Not fake dude! This is really possible. Do some research first next time!

Hi could you send me the schematic? Thanks.
