Definitions

  • the invention relates to the field of secret communication and can be used as a means of protection against listening to confidential negotiations conducted in closed or open space.
  • a device for protecting confidential conversations which comprises a series-connected generator of an electric noise signal in the frequency range of masked acoustic information, an electro-acoustic emitter and a device for processing masked acoustic information, which contains a microphone, headphones by the number of negotiators and a two-channel digital adaptive filter, to the first input of which the microphone output is connected, the second output of the generator is electrically connected to the second input noise signal in the frequency range of the masked acoustic information, and the output - head phones (see Cl. RF W 2155453, CL H04K 1/00, Cl. 5.07.99, publ. 27.08.2000 “How to protect confidential negotiations and a device for its implementation).
  • a disadvantage of the device is its complexity and the resulting, as a result, the possibility of discreetly incorporating a listening device into the device.
  • the closest in technical essence, the achieved result and selected as a prototype is a device for negotiations, containing a sound duct in the form of a flexible hose with an intermediate element integrated in its middle in the form of two gutters entering one another. Both free ends of the sound duct extending from the intermediate element branch into three branches: two of them are auditory tubes, the third ends with a mouthpiece for negotiations (see A.S. USSR Zh28396, class 62 b, 24 declaration 04.04.31, publ. 30.1 1.32 “A mobile device on an airplane))).
  • the disadvantage of this device is the inability for negotiators to observe confidentiality, because words uttered by one of the negotiators are heard not only by the second negotiator, but also by those around him.
  • the objective of the present invention is to ensure confidentiality during negotiations, by preventing the spread of sound outside the intercom. This problem is solved due to the fact that in the known device for confidential negotiations, containing a sound pipe made in the form of a hollow pipe, each end of which is equipped with a sound pickup element connected to the sound pipe and at least one ear pipe, according to the invention, as a sound pickup element a soundproof mask is used.
  • the sound pipe can be made in the form of two hollow pipes, with one end of each of the hollow pipes of the sound pipe communicating with a separate soundproofing mask, and the second end of each of the hollow pipes acts as a separate auditory tube.
  • the device may further comprise a hollow chamber integrated in and communicated with the sound duct.
  • the device may further comprise at least one additional auditory tube in communication with the hollow chamber and / or at least one communication with the hollow chamber through the hollow tube, and an additional soundproofing mask.
  • the hollow chamber of the device by means of a membrane of translucent material can be divided into compartments isolated from each other, each of which is communicated with a soundproofing mask and / or auditory tube, intended only for one of the negotiators.
  • the hollow chamber of the device by means of a membrane of translucent material can be divided into two tiers, the continuous cavity of one of which is connected to the auditory tubes, and the cavity of the second tier, separated by a membrane of sound-conducting material, is connected to each other by soundproof masks, each soundproof mask being communicated with one of the compartments of the second tier of the hollow chamber.
  • At least part of the parts of the device can be made of translucent material.
  • the implementation of the device in the claimed form eliminates the spread of sound outside the intercom, because a sound-insulating mask pressed to the mouth of one of the negotiators, directing the sound through the sound conduit communicated with her to the ear pipe fixed in the ear of the other negotiator, blocks the possibility for the sound to escape into the surrounding space, thereby ensuring confidentiality of negotiations.
  • the implementation of the sound pipe in the form of two hollow pipes eliminates the interference arising from the simultaneous conversation of negotiators. This is because the sound of the speech of one of the negotiators spreads to the ear of the other negotiator or to the hollow chamber through his hollow pipe, and the sounds of speech that he hears from other negotiators go to him through the second hollow pipe either directly from the partner, or from the hollow chamber. In other words, in one pipe party talks, but on the second listens to the interlocutor.
  • the claimed device allowing to exclude the spread of sound outside the intercom, ensures the confidentiality of negotiations, and due to the high quality of sound transmission, the ability to simultaneously speak and listen to a negotiating partner, the ability to negotiate in conference mode, compliance with sanitary standards during negotiations provides increased comfort for negotiators.

  • a device may be, for example, elastic straps (not shown in the drawing) for tightly fixing mask2 on the face of a negotiator.
  • soundproof masks2 are fixed at the ends of this hollow pipe 1, and the pipe 1 itself in the areas located near each of the makok2 is equipped with one or two branches acting as auditory tubes Z connected with the hollow pipe 1 .
  • one soundproofing mask2 is fixed at one of the ends of one pipe 1, and the second at one of the ends of the second pipe 1, while the free ends of the pipes are branched into two branches (for fixing in two ear) or without branching (for fixation in one ear), act as auditory tubes
  • the ends of the auditory tubes ⁇ for the convenience of their fixation in the ears of the negotiator are equipped with metal nozzles with olives (not shown in the drawing).
  • a hollow chamber4 for example a hollow plastic box, is built into the middle of the sound pipes. Pipes 1 are screwed or glued into the walls of this box so as to ensure communication between the cavity of the chamber 4 and the hollow pipe 1 of the sound duct.
  • the hollow chamber4 can be divided into compartments5 and / or tiers by means of a membrane7 made of a translucent material that provides good sound transmission between adjacent tiers and / or compartments5 of the camera4 (this may be, for example, plastic material used to make the membrane in a stethoscope). Use the device as follows.
  • the negotiators being in close proximity to each other, for example, at a negotiating table or in a car, fix soundproof masks2 on their faces, and earpieces in their ears and negotiate by distributing the sound of the negotiators' voice through pipe / pipes 1 of the sound pipe. This prevents the spread of speech in the environment and guarantees the confidentiality of negotiations. To enhance privacy in the meeting room, music or background noise may be included.
  • the implementation of the device with a sound pipe from two pipes creates comfortable conditions for negotiations due to the high quality of sound transmission and the ability to simultaneously speak and listen to a partner, and the built-in hollow camera4 allows you to negotiate in conference mode.
  • the device can be manufactured at any enterprise specializing in this industry, as this requires well-known materials and standard equipment, and is widely used in the field of secret communications, i.e. is industrially applicable.
