Sound Ring / Ring

Sound Ring

Currently, the deadly weapons of agents are already very comprehensive, but non-lethal weapons are not very complete. Today's weapons are generally a blow to the physical touch of criminals, but this can easily harm ordinary civilians and is not easy to control. The sonic ring solves this problem very well. It can quickly subdue the criminals by directing the audio shock wave to the criminals. At the same time, it can protect the civilians well, even if it is accidentally injured.
