Introduction of the small black box: The “small black box” is also called the Tesla coil. The Tesla Coil is a transformer (resonant transformer) that operates on the principle of resonance. It was developed by the Serbian-American scientist Nikola· Tesla invented in 1891, mainly used to produce ultra-high voltage but low current, high frequency AC power.

The working principle of the small black box: the strong electromagnetic pulse generated by the Tesla coil attacks the smart lock chip, causing the chip to crash and restart, and some smart locks automatically unlock after restarting by default.
