Anti-Recording Microphone Guard Ultrasonic Acoustic Sound Wave Generator to Stop Smartphone Digital Recording

F10 Jamming & Acoustic Coverage

• Interference Mechanism: Emits high- and low-frequency mixed ultrasonic sound waves directly targeting microphone diaphragms.
• Audio Protection: Forces recording devices to capture only an unrecoverable, distorted "hum". Captured audio cannot be reconstructed by forensic software.
• Shielding Range: Covers a 300-degree all-round perimeter.
• Effective Area: Optimised for 1.5 to 3 square metres when placed on a desk directly next to target recording threats.
• Target Compatibility: Neutralises microphones on smartphones, tablets, digital dictaphones, and hidden wireless bugs.

Electrical & Power Specifications

• Internal Battery Capacity: 4,000 mAh / 3.6V lithium battery.
• Power Consumption: Input voltage of 5V / 1,000 mA; Output voltage of 5V / 1,000 mA.
• Operational Battery Life: 60 to 120 minutes of continuous jamming on a single charge.
• Standby Current Draw: 10 mA operational standby; 60 uA complete shutdown current.
• Acoustic Sound Pressure: Max 120 dB at 30 cm distance.

Interface & Hardware Features

• Chassis Dimensions: 140 mm × 65 mm × 22 mm.
• Output Modes: Dual power gears (high/low intensity) distributed across three directional emitter arrays.
• Wireless Remote Control: Shipped with a 433 MHz wireless sensor remote operating up to a distance of 1 to 50 metres for discreet activation.
  

F11 Jamming & Acoustic Coverage

• Interference Mechanism: Emits ultra-low frequency ultrasonic sound wave algorithms. It mixes high and low-frequency audio bands to overwhelm recording diaphragms with unrecoverable acoustic distortion.
• Total Coverage Radius: Safeguards an expanded physical space spanning 1 to 6 square metres.
• Emission Profile: Spreads defensive waves over a complete 360-degree shielding angle through 5 physical output directions (compared to the 300-degree coverage of the F-10).
• Acoustic Intensity: Max sound pressure output up to 90 dB to 120 dB depending on directional intensity gear selection.

F11 Electrical & Power Specifications

• Internal Battery Capacity: 8,000 mAh integrated lithium battery bank (double the 4,000 mAh capacity of the F-10).
• Mains Integration: Equipped with a dual-mode system supporting standard US/EU 100V–240V AC power inputs for uninterrupted 24/7 boardroom security.
• Operational Battery Runtime: Sustainable continuous standalone jamming for 2 to 4 hours with all emitter sides activated, or up to 6 hours on half-side eco-mode.
• Power Output: Dual-purpose design acts as an emergency USB mobile device power supply (Output: 15V / 5A).

F11 Hardware & Control Attributes

• Chassis Dimensions: 160 mm × 80 mm × 93 mm.
• Total Enclosure Weight: Approximately 665 grams.
• Power Adjustment Gears: Dual mechanical power gears (High-Intensity focused / Low-Intensity discrete).
• Wireless Remote Control: Utilises a 433 MHz RF pairing remote for covert, long-range activation spanning 1 to 50 metres.
  

F12 Jamming & Acoustic Array

• Transmitter Configuration: Engineered with 66 individual ultrasonic transmitter heads distributed across its chassis faces to maximise acoustic sound pressure.
• Interference Angle: Provides true 360-degree full omnidirectional coverage fields.
• Defensive Mechanism: Blends high and low-frequency ultrasonic sound wave algorithms to vibrate microphone diaphragms. The resulting acoustic white noise hum completely masks speech and cannot be cleaned by audio-forensic software.
• Maximum Target Range: Expands protection out to a radius of 8 metres (26.2 feet) in all directions.
• Target Compatibility: Neutralises voice microphones on smartphones, digital voice recorders, dictaphones, and concealed spy bugs.

F12 Electrical & Power Specifications

• Internal Battery Capacity: Features a high-capacity 9,800 mAh / 12.6V lithium-polymer battery.
• Continuous Run Time: Sits between 2 to 4 hours when operating at peak maximum output (or up to 8–15 hours under lower eco-power modes/standby configurations).
• Power & Consumption: Rated at 20 Watts active power output.
• Mains Charger Interface: Driven by an external 15V / 5A power supply adapter that simultaneously charges the unit and supports continuous 24/7 fixed boardroom runtime.
• Visual Power Tracking: Utilises a 4-segment LED power indicator on the housing to monitor active battery levels.

F12 Physical Attributes

• Chassis Dimensions: Compact tabletop tower footprint measuring 253 mm × 131 mm × 103 mm.
• Gross Structural Weight: Approximately 1.94 kg (4.3 lbs), providing heavy desktop stability against vibrational acoustic feedback.
• Enclosure Materials: Impact-rated ABS polymer matched with internal structural metal heat-sinking.
  

F18 Jamming & Acoustic Coverage

• Interference Angle: Delivers a full 360-degree omnidirectional perimeter field.
• Defensive Radius: Effectively suppresses voice recording devices from 2 to 8 metres away.
• Acoustic Mechanism: Emits multi-frequency ultrasonic sound waves that target the physical diaphragms of hidden microphones. It creates an unrecoverable "white noise hum" that cannot be cleaned by audio-forensic software.
• Target Compatibility: Neutralises audio collection on smartphones (both Apple iOS and Android), hidden digital voice recording pens, and active wireless bugs.

F18 Electrical & Power Specifications

• Internal Power Supply: Equipped with a high-capacity 14.8V / 5,200 mAh polymer lithium battery pack.
• Active Battery Runtime: Supports up to 3.5 to 5 hours of continuous standalone jamming on a single charge.
• Charging Interface: Features a modern USB Type-C hardware port.

F18 Physical Attributes & Mechanics

• Structural Composition: Built from a blend of impact-resistant ABS polymer and high-grade wood wrapping to blend into executive office furniture.
• Chassis Footprint: Measures 182 mm × 122 mm × 104 mm.
• Total Structural Weight: Weighs approximately 1,352 grams to maintain tabletop placement stability.
• Activation Triggers: Features three distinct operational modes consisting of manual button pressing, a 433 MHz wireless remote control, and sound/voice-activated automation
