Operating within a DC 15–24V range and delivering 15W of power, this Tesla coil produces visible plasma arcs while functioning as an innovative plasma speaker capable of playing music through air vibration.

Equipped with a 3.5 mm audio input, the device allows seamless connection to smartphones, computers, or MP3 players, transforming electrical discharges into audible sound. Its arc length can reach up to 5–10 mm at optimal voltage, providing a visually impressive display of electrical energy. In addition to sound generation, the coil supports wireless power transmission, enabling it to light LEDs and fluorescent lamps without direct contact.

Thanks to its compact PCB design and efficient performance, this Tesla coil can operate continuously for extended periods. It is ideal for educational demonstrations, STEM learning, and hands-on experimentation. Safety considerations such as heat dissipation and maintaining distance from electronic devices ensure reliable and secure operation during use.
