hello, i recently saw videos of home built plasma arc speakers in action and i tought they looked really neat. I would deffinetly like to build my own plasma speaker but finding complete schematics on the internet proved almost impossible, i did find this schematic https://www.barlowlabs.upgradecolumbus.com/YSU Webpage/ADVcircuits/SparkSpkr/Spark Speaker.pdf but this is not a complete schematic for an arc speaker (the arc speaker schematic and design begins on page 7, the designs before are for a plasma speaker shooting out into open air). The pdf seems to use a flawed design of altering the frequenzy the arc arcs across the 2 ignition coils to produce sound, which means that the arcing occurs way to seldom and causes one to hear the actual arcing since it arcs at the frequenzy of the music being played. What i have understood of plasma speakers is that the arcing should occur at a set frequenzy prefferably above 45 Khz and that the music should then be modulated in on that frequenzy, causing the arcings to be of different strenght or time making the air expand differently depending on the heat of the arc.
I have built a plasma speaker following the schematic but it proved very bad, producing mostly hiss and noise sounds only some music was audiable and the amount of arcing was completely dependent on the music suggesting the design only changes at which frequenzy the transistors should open and close. And this is not what is desired.
So i would require help for a design that would make an arc occur at around 100Khz constantly between a flyback and ground or 2 automotive ignition coils or 1 ignition coil and ground. And then the audio would need to be modulated into that arc, increasing the heat of the arcs depending on the music being played.
i would greatly appreciate help on this project
