Description:
Using Advanced Ultrasonic Mixing Technology, AJB-331 cellphone audio jammer box can block recording from cellphone eavesdropping seamlessly and senselessly without causing any disturbance.
By emitting ultrasonic noise that is imperceptible to the human ear, this audio jammer box can effectively jam the microphone of cellphones. Communication audio cannot be recorded nor restored.
Features:
◆ 100% Protection: The audio jammer adopts ultrasonic microphone jamming technology that effectively neutralizes any eavesdropping apps on the cellphone by emitting a meaningless noise.
◆Safe and Undisturbed: Thanks to ultrasonic microphone jamming technology, there is no audible noise or electromagnetic radiation. This technology does not damage cell phone hardware, nor does it block any calls, SMS, or other network communications.
◆ Easy to Use: It offers an out-of-the-box experience and activates upon placing a cell phone on it. It also has indicators for jamming activity and wireless charging.
◆Wireless Charging: The cellphone audio jammer box provides 10W wireless charging. Its optimized charging management and heat dissipation design allow for long working periods.

Ultrasonic Mixing Technology
Based on CPLD/FPGA Chip embedded with encrypted algorithm, it generates ultrasonic mixing data model and exports ultrasonic signals, forming a harmonic effect to deceive the recording device. The microphone/pick up can only receive the harmonic ultrasonic signal generated by jammer, can not pick up the normal voice signal.
Safe, Silently and Undisturbed
Thanks to ultrasonic microphone jamming technologies, there is no audible noise or electromagnetic radiation. This technology does not damage cell phone hardware, nor does it block any calls, SMS, or other network communications.
Wireless Charging
The cellphone audio jammer box supports 10W wireless charging function. Its optimized charging management and heat dissipation design allow for long working periods.
Easy to Use
AJB-331 cellphone audio jammer box offers an out-of-the-box experience. It will activate upon placing a cell phone on it. There are LED indicators for jamming activity and wireless charging.
