The so-called acousto-magnetic is a resonance phenomenon generated by the principle of tuning forks. When the frequency of the transmitted signal (alternating magnetic field) is consistent with the oscillation frequency of the acousto-magnetic tag, the acousto-magnetic tag will cause resonance similar to the tuning fork and generate a resonance signal (alternating magnetic field); After the receiver detects 4-8 consecutive (adjustable) resonance signals (once every 1/50 second), the receiving system will issue an alarm.
