Ultrasonic Tissue Box Audio Jammer U-TB-80

This professional voice recording jammer, which looks like a tissue box, works on the principle of a hidden ultrasonic sound screen.

Introduction of the Ultrasonic Tissue Box Audio Jammer U-TB-80

This tissue-box style voice jamming system is a covert ultrasonic blocker disguised inside a standard tissue box, crafted to secure confidential conversations from nearby microphones or hidden recording devices. Using 84 high-frequency emitters, it produces a full 360° interference zone reaching up to 8 meters, scrambling the audio input of smartphones, covert bugs, portable recorders, and other listening tools placed around a desk or meeting table. A long-lasting lithium-ion battery powers the unit for up to 10 hours, and the discreet charging port maintains the appearance of an ordinary office item. Users can activate the jammer through a mobile app, a wireless remote, onboard controls, or an AI-based voice detection mode for hands-free operation during private discussions.

Advantages and Functional Features

Disguised Tissue Box Design. The jammer's internal components are built into a lifelike tissue box casing, allowing it to blend seamlessly into conference rooms, workspaces, executive suites, or private meeting environments.
Full-Circle Ultrasonic Coverage. Eighty-four ultrasonic transmitters produce an all-around interference field, disrupting microphones located anywhere within the 0 - 8 m protective radius.
Multi-Device Recording Interference. Engineered to interrupt audio capture on smartphones, smartwatches, hidden wireless bugs, Bluetooth or Wi-Fi recording gadgets, voice-activated recorders, wired taps, and pen-style listening devices within range.
Versatile Control Options. Choose between app-based operation, remote control use, top-panel button input, or intelligent voice-activated triggering—ideal for discreet or silent activation in sensitive situations.
Long-Duration Battery Performance. The high-capacity lithium-ion battery delivers up to 10 hours of continuous jamming, making it suitable for full-day meetings and confidential sessions.

Applications

This device is designed for high-risk settings such as boardrooms, executive workspaces, government or enforcement facilities, legal advisory rooms, journalist interview areas, and other locations where covert recordings may pose a threat. Placing the tissue-box enclosure on the meeting table establishes a localized ultrasonic barrier that disrupts nearby microphones without drawing attention.

It is optimized to interfere with microphones in phones, mini recorders, secret audio bugs, and other compact devices located within the 0 - 8 m ultrasonic zone. For the best performance, situate the tissue box close to participants so that all potential recording devices remain within the immediate suppression area.

While highly effective against common consumer microphones, results may vary depending on device type and the sophistication of newer audio-processing systems.

(*) Note: The mini-program supports independent control of 5 Audio Jamming Devices (with Bluetooth). It allows you to turn the Recording Blocker Devices on and off, adjust their power, switch mode, modify passsword and provide real-time information of their current working status and battery level. Using the program allows for a higher level of stealth in the use of Audio Jammers, compared to a standard remote control.
