Koyzsen Music Tesla Coil Arc – Desktop Plasma Loudspeaker & Science Demonstration Toy

Experience science and sound in one dazzling desktop device

The Koyzsen Music Tesla Coil blends high-voltage arc visuals with square-wave music, turning a classic experiment into a captivating desktop toy. Built to excite curiosity, it offers a tangible way to explore energy transfer, resonance, and the interaction between electricity and sound. The compact 100 × 100 × 50 mm chassis packs a surprisingly energetic arc that can light a small atmosphere lamp or simply glow in a dramatic blue-white arc, making science feel present and real.

At the heart of this unit is an SSTC-based coil that translates audio into visible action. By connecting to your smartphone or using the built-in USB song pack, you’ll see the arc pulse in time with the beat, creating a visceral link between rhythm and electricity. A new version of the device removes automatic sleep, so you can connect and explore at any time, whether you’re preparing a quick demonstration or diving into a longer science session.
