Plasma Speaker, Singing Arc
No, this isn’t the sequel to Crouching Tiger, Hidden Dragon. This is a video of a plasma prototype speaker design.
The complete prototype circuit is shown here built on a single PCB. The reflector is made from PVC pipe with a rear mirror. EHT now slightly lower and the gap size has been reduced. Track is ‘Hold Me Now’ from the Thompson Twins - chosen purely for it’s good dynamic range, vocals & clever percussion !
Head on over to timetec’s YouTube channel to see several other DIY setups he’s produced.
