F11 Ultrasonic Anti-Recording Voice Jammer Desktop Speaker with 360° Coverage & 8000mAh Battery

Maintaining strict confidentiality during executive meetings, legal briefings, or high-stakes business negotiations is challenging when unauthorized listening devices are nearby. For instance, holding sensitive conversations in boardroom spaces or dining establishments across Dhaka carries constant risks of hidden voice recorders or covert smartphone tapping. Fortunately, the F11 Anti-Recording Voice Jammer solves this privacy threat by disguising its counter-surveillance hardware inside an unassuming desktop Bluetooth speaker shell. Sitting naturally on conference tables without exciting suspicion, it projects high-frequency ultrasonic waves across a 360-degree shielding radius to disrupt target recording devices seamlessly.

MEMS Microphone Diaphragm Overload and Un-Erasable Noise Spectrum

Standard white noise generators create loud, distracting audible chatter that disrupts professional dialogue. Beyond that, basic software-based voice scramblers can often be filtered out using advanced digital audio recovery algorithms. However, this advanced counter-measure emits intense ultrasonic frequencies above 20 kHz that human ears cannot consciously perceive. These invisible waves physically vibrate the micro-electro-mechanical systems (MEMS) and condenser diaphragms inside modern smartphones, dictaphones, and hidden bugs. As a result, hardware diaphragms become completely overloaded, recording only an unrecoverable digital buzz that renders captured audio entirely unintelligible.

Dual AC/DC Mains Power Flexibility and 8000mAh Built-in Battery

Relying solely on wall socket connections limits where you can hold confidential conversations in field locations. Because of this, active executives and legal professionals require flexible power options that adapt to any meeting room setup. Therefore, the F11 comes equipped with an internal 8000mAh rechargeable lithium battery that delivers 4 to 9 hours of continuous standalone jamming. When deployed inside fixed office setups, it runs directly on AC mains power for uninterrupted 24/7 acoustic protection, covering an effective jamming radius of 1 to 6 meters spanning up to 6 square meters.
