The principle of this acoustic magnetic hammer is to use the resonance phenomenon generated by the tuning fork principle to achieve zero false alarms. When the frequency of the emitted signal (alternating magnetic field) of the clothing anti-theft device is the same as the vibration frequency of the acoustic magnetic tag, the acoustic magnetic tag, similar to a tuning fork, will resonate and produce a resonance signal (alternating magnetic field); When the receiver detects 4-8 consecutive (adjustable) resonance signals (once every 1/50 second), the receiving system will announce an alarm.

The characteristics of the acoustic magnetic system are high anti-theft detection rate, theoretically zero false alarms, less susceptible to metal foil shielding, good anti-interference performance, and a wide protected exit (a single system can protect up to 4 meters, depending on the size of the label).
