Musical Tesla Coil Plasma Speaker with Acrylic Shell

Musical Tesla Coil Plasma Speaker with Visual Arc Display

Bring science, sound, and light together with this Musical Tesla Coil Plasma Speaker. Designed for hands-on experimentation and engaging demonstrations, it converts electrical energy into visible arcs and audible music. The golden Tesla coil is housed in a clear acrylic shell, allowing you to safely view the discharge while exploring concepts in electrodynamics, acoustics, and wireless energy transfer. When connected to a compatible audio source, the plasma arc vibrates at audio frequencies, turning the discharge itself into a loudspeaker.

The module operates from a DC input range of 8-32 V. At around 8 V it can begin lighting gas-filled bulbs; from about 13 V it can generate arcs and play music; around 24 V typically offers the best balance of sound quality and arc performance (do not exceed 32 V). A larger heat sink and built-in circuit protection support stable operation and help protect your connected audio devices. Multiple interchangeable discharge terminals (needle, ion windmill, ion wreath) let you switch between different visual effects and experiments, from spinning ion windmills to shaking ion wreaths. The included bulbs demonstrate wireless excitation in the high-frequency field.

The clear acrylic shell provides a protective barrier while maintaining full visibility of the coil and arcs, making it suitable for classroom demonstrations, lab projects, and at-home exploration. With plug-and-play operation, no grounding required, and wide compatibility with common music players via a 3.5 mm audio cable, this Tesla coil offers an accessible way to explore high-voltage phenomena, plasma acoustics, and wireless lighting in a controlled environment.

Why It's a Smart Choice

• Combines visual arcs, music playback, and wireless lighting for multi-sensory demonstrations.
• Wide 8-32 V DC input range with circuit protection supports flexible, safer operation.
• Interchangeable discharge terminals enable multiple experiments and teaching scenarios.

FAQ

Q: What power supply do I need to use with this Tesla coil?
A: Use a DC power supply within 8-32 V. For arc and music playback, 13 V or higher is recommended, with around 24 V typically giving the best sound quality. Do not exceed 32 V input.

Q: How do I play music through the plasma speaker?
A: Connect the included audio cable: one end to the Tesla coil's audio input and the other end to a music source such as a phone, computer, or MP3 player. Power on the coil and start playback on your device; the arc will emit the sound.

Q: Can it light bulbs without direct contact?
A: Yes. When operating, the high-frequency electric field can excite nearby gas-filled lamps. Hold the metal base of the included bulbs and slowly move them toward the coil; they will light once within range without a wired connection.

Q: Is it suitable for classroom or lab use?
A: The transparent acrylic shell, visible arcs, and multiple accessories make it well suited for demonstrations of high-frequency fields, plasma sound generation, and wireless excitation, provided it is used under appropriate supervision and safety guidelines.
