- DIY kit for hands-on building: This electronic mini coil plasma speaker kit lets you assemble the components yourself, delivering the satisfaction of creating your own speaker. - Resonance-based coil transformer: The coil operates on the principle of resonance. It was invented in 1891 by Serbian scientist Nikola. It produces ultra-high voltage with low current high-frequency AC and has historical use in electrical lighting, fluorescence spectroscopy, X-ray, electrotherapy, and radio energy transmission. - Full-energy output and ignition capability: The rear end of the coil provides full-energy output, which can be used for ignition purposes and adds a visually striking effect to the speaker setup. - Separator lamp function: When the coil is powered, it can light a fluorescent lamp, adding an additional visual element to the setup. - Practical use scenarios: - Educational demonstrations of resonance, high-voltage/high-frequency AC, and coil operation for electronics learners. - Science fair project or hobbyist build to explore plasma visual effects in a compact kit. - Visual display component for a desk or workshop setup, showcasing dramatic plasma lighting in tandem with the speaker system.
