Tesla coil, an electrical transformer that uses high-frequency alternating current (AC) to increase voltage. Because of the extremely high voltage, the current in the Tesla coil can travel through the air, powering or damaging nearby electronic devices, often creating lightning-like currents. It is a famous invention of the brilliant genius Nikola Tesla .
Although Tesla coils produce extremely high voltages, the high frequency of the current usually means that most people can approach the device and even be struck by the arc without being injured. The spectacular effects produced by Tesla coils have made the device popular in science fairs,...
Not only discharging electricity, with intelligence and creativity, humans also make Tesla coils "sing".
The Singing Tesla coil , also known as the thoramin, zeusaphone, or "music of electricity", is a variation of the Tesla coil. It produces musical notes by modifying the emitted electric current into low-fidelity square waves, similar to the sound waves of electronic musical instruments.
The high-frequency signal acts as a carrier wave, its frequency is beyond the range of human hearing. Therefore, digital editing helps to create sounds within the range of human hearing.
Modifying the path of the electric spark in the air creates musical notes. The sounds they produce cannot have many states because Tesla coils produce square waves, not sine waves. But Tesla coils can absolutely sing you songs with simple melodies and notes.
At the 2007 SXSW music event, Joe DiPrima and Oliver Greaves made the Tesla Coil "sing" simple melodies. After seeing this performance, David Nunez first coined the phrase "singing Tesla coil". The phrase "singing Tesla coil" has since become popular and widely used.
