Thin, modular & expandable, for direct placement underneath tables and desks facing the subject seating area.

The Ultrasonic Speech Protection Strip has 3M adhesive on the top, back, and bottom sides of the 23 transducer array, a supplied separate control unit that houses the electronics is plugged into the array along with the provided power supply. 

This jammer is expandable, up to 3 standalone jammer strips can be purchased separately and attached together running in parallel on the same driver via 5.5x2.1mm DC power jacks, offering you a very flexible & expandable jamming solution in tight spaces, additional jammer strips can be found here

These strips are intended to be placed underneath tables within offices and meeting rooms and purposely installed facing the seating area of your meeting attendees and clients. This Jammer targets mobile phones and recorders sitting in pockets or tucked between a person's legs which may be secretly recording discussions without the recording device being in plain sight. The Speech protection strip may also be installed overtly based on your needs.


Each Jammer array strip measures (L) 15.7in, (W) 0.59in, (H) 0.39in.

This ultrasonic jammer uses our Series S driver and is capable of operating on a 9V battery or with the included AC power USB adapter, both power options are provided, this allows for different powering options without having to worry about battery replacement. This driver generates true white noise using sinusoidal waves for precise ultrasonic frequency modulation without frequency shift. The Ultrasonic waves being emitted safely offer an effective disruption attack which is far greater than any other digitized “white noise” technology on the market (commonly known as "Ramblers") which can be dissected and defeated using audio forensic software. 

By creating an ultrasonic field around a given area, you can render all microphones disabled and useless while continuing your conversations privately. Recorders that are within range of a Series S jammer will not be able to capture intelligible audio, microphones are highly susceptible to ultrasonic noise, and because we are now modulating them in a specific way which is even more disrupting, audio that is captured cannot be reverse-engineered using forensic software (Phonexia, Foenics, Diamond Cut, Cardinal etc.) Instead, Recorded audio will be nothing but unintelligible jarring white noise. 

The Series S jammer will also completely disable smartphone microphones, & just like the Series X, Series S is also capable of completely disabling voice-control and smart home/AI assistants, across several major technology manufacturers and platforms. If it utilizes a microphone to hear your commands, this device will disable it, this includes Google Nest products, Amazon Alexa, Echo, Sonos, Vehicle smart assistants (Toyota, Tesla, Ford, Dodge, Honda, Mazda) virtually any smart device or vehicle AI currently on the market.

Several units can be placed facing different directions for complete omnidirectional protection. Each transducer has a 90-degree beam field, utilizing several jammers will cause an overlapping field of suppression in larger areas.

We designed our Jammers for rapid deployment, capable of operating on a 9V li-ion battery (readily available on Amazon) or Alkaline 9V, but they are most effective when operating on AC power with the included adapter.

*These devices protect you from being recorded by completely suppressing recording devices and digital recorders. The intended use of this device is to be placed directly near devices prior to sensitive meetings.

*The Series S can be configured in any shape to meet your office needs, arrays can be elongated and disguised as soundbars, speaker boxes, office furniture, or custom to your specifications and office/vehicle needs.
