Anti Interference/Prevention of Mobile Recording Pens Blocking Instruments/Anti Eavesdropping Monitoring Devices for Office and Conference Room Conversations

• Model NO.: XY-LY001

Product Description

A sound jammer is an electronic device that uses a dual system of CPLD and FPGA for air frequency conversion and muting, as well as a full range output system for high, medium, and low frequencies. The combination of CPLD and FPGA dual systems can improve the effective coordination between components, thereby achieving the stable frequency conversion and crossover function of the ultrasonic probe in the air. The basic principle is to generate high-frequency interference signals that interfere with the normal operation of recording equipment, making it unable to record sound.
