I am entirely new to the field of electrical engineering. I want to learn more with the current goal of designing/building my own set of plasma speakers. Where should I begin?

google it. here are a few examples: *wierd schematic ,r:14,s:0,i:119
there are so much info on this, how can you not dig something up withing 30 seconds.
as for a little theory: the switching of the hv transformer is in the range of sound that your ears can't pick up. but you can tell the difference between an arc that is on, and an arc that is off. so if you switch the arc on and off(pwm) according to the audio input, you can hear music though the arc. another way to do this is to change the duty cycle of the arc according to the music to get full analog input range.
