Singing Tesla coils:A tesla coil is an air cored resonant transformer.
Creators of the original Singing Tesla Coils, the crew of ArcAttack uses high tech wizardry to present music in a whole new light. ArcAttack employs a unique DJ set up of their own creation (an HVDJ set
up) to generate an 'electrifying' audio visual performance.
In an interview how it works is this:
Giovanni: The way our coils work is by turning the spark itself into an actual speaker. Say you place a sine wave of 440hz out of a speaker. That speaker will move 440 times a second to create the pressure waves that we hear. Instead of a moving diaphragm, we basically have an on/off spark. so we play the same 440hz tone through the coil and the spark will stop and start 440 times, and each time it starts it ionizes the air creating pressure waves.
