Can anyone recommend a miniature transducer which would be capable of producing the sound of a high voltage spark discharge? I'm trying to find something that when pulsed with a DC voltage will create that characteristic sharp 'crack' sound, preferably loudly.
TIA
Hint: please try to avoid rude and unhelpful retorts like "what do you want to do that for?" and suchlike.
Back when the world was entirely Analog (early '70's) I had occasion to develop a chip that would replicate the sounds of the typical GM chime, beep, etc, for various alarm functions in the car, allowing a single speaker to replace several different mechanical noise makers.
I did it by simply recording the sounds, then designing a "function generator" on-chip that matched the waveforms of those sounds.
Fun project ;-)
You can probably easily do it now with a digitized recording and a DAC. ...Jim Thompson

Just about anything that will generate a small amount of static electricity, when applied to the microphone input of an audio amplifier amplifier. Piezoelectric, triboelectric (friction), magnetic induction, etc. Anything that will produce a voltage should work into an amplifier.
No quarter asked or given:
What are you trying to accomplish?
What do you have to work with?
What have you tried so far and what happened?
Here's what a real spark gap transmitter sounds like: Obviously, this is not what you hear when the mad scientist turns on his diabolical machine, which invariably features a furiously sparking Jacobs ladder.
So, is it something like these that you're trying to simulate? Or perhaps with a little less shock and awe?

Triggered air spark gap? More joules more louds. 20 kV and 10 uF through an air gap is indistinguishable from a healthy high voltage spark discharge. Or a 30-06.
Well, I am curious as to what you want to do that for.
This may be as useless as you dread, but how about a model airplane engine spark plug, plus a coil from a weed-eater? Because nothing sounds quite as much like a high voltage spark discharge as a high voltage spark discharge.
