Jammer of voice recorders
The device is designed to protect against voice recorders and “bugs” during a private conversation.
Structurally, the device contains 22 ultrasonic emitters and a sound emitter on the top panel of the device. In order to apply the device, you need to place it in special case and direct it to the side of the interlocutor. During the conversation, the owner of the device warns the interlocutor of the importance of the topic of negotiations and turns on the device using the remote control. The acoustic emitter creates a speech-like interference, which clogs the conversation of the interlocutors. The ultrasonic emitter generates an ultrasound stream, which reduces the sensitivity of the microphone in a mobile phone or voice recorder at the interlocutor.
Most modern mobile phones (Samsung, iPhone, etc.) will be suppressed in “silent mode” – without the inclusion of acoustic noise. But suppression of other phones is possible only with the simultaneous use of acoustic and ultrasonic interference.
The volume of acoustic noise is set in such a way, voice recorders installed outside the conference table, cannot record the conversation of the participants in the negotiations. It is recommended to direct the ultrasonic emitter upwards.
The device works autonomously. When using the charger supplied in the kit, the operating time increases.
Battery charge – indicated by the LED above the charging socket. When the color of the LED changes from red to green, the charging process is completed.
Work with the device:
The device turns on with the power switch. The following operating modes are possible using the remote control:
A – noiseless ultrasound suppression – suppresses all high-quality voice recorders
B – device shutdown
C – ultrasonic + quiet acoustic suppression.
D – ultrasonic + loud acoustic suppression.
