AUP-2 Ultrasonic Audio Jammer with White Noise Generator and 6 Speakers

Small size, dual acoustic protection. The AUP-2 works in two complementary ways, integrating an ultrasonic technology and a white noise generator into one unit, and using multi-frequency overlapping air spiral sound wave technology to create a rich acoustic environment.

• Ultrasonic interference produces high-frequency sound waves, helps disturb microphone pickup
• White noise generation for continuous background noise masking, helps mask surrounding conversations
• Multi-frequency sound output helps improve interference consistency in different indoor environments.

Equipped with 6 high-performance speakers, it delivers adjustable coverage from 1 to 7 meters with a 90°–180° sound output angle, the built-in system reaches a maximum interference intensity of 85dB.

Compared with traditional single-function ultrasonic microphone recorder disruptor, this flexible design makes AUP-2 easier to position in meeting rooms, offices, private spaces, and other indoor environments where audio privacy matters.

The built-in rechargeable battery supports approximately 3 hours of continuous operation, allowing the speech blocker to be used without being connected to a power source.

Need longer operation? Simply connect it to an external power supply. When plugged in, the AUP-2 can operate continuously for up to 24 hours, making it suitable for extended indoor use.
