2Pcs TWS Dual Channel Bluetooth Speaker Esound Plasma Speaker Tesla Coil
Features:
.Acrylic shell, fanless design, arc up to 1.5cm, non-traditional speaker sound principle
.It can work continuously for more than several hours, working voltage is 12V, power is only 30W, silent cooling fan, sound arc is placed on the second layer, glass cover is protected to avoid touching, safe and reliable
.Although the power is only 30W, the maximum volume can reach 70dB
.Sounding principle: The high-voltage breakdown air induced by the transformer secondary makes the air temperature extremely high and becomes plasma. When the air temperature at the discharge end rises sharply, the air will expand around, squeezing and oscillate the surrounding air to produce sound
.Through audio modulation, the chip generates a square wave signal whose frequency or duty cycle changes with the music, and drives the switch tube (generally used field effect tube) of the subsequent stage to turn on and off, so that the primary of the high-voltage package flows accordingly. The regularly changing current induces a high-voltage arc in the secondary coil of the high-voltage package. The air heated by the arc makes a sound when the audio signal vibrates.
.Instructions for Use: 1. After receiving it, please check whether the equipment is damaged, and then turn on the power; 2. If only the blue light is on after the power is turned on, and there is no arc, please fine-tune the middle part of the discharge wire to a 5mm gap.
