DEVICE FOR ELECTRICAL COMMUNICATION BETWEEN EXTERNAL SUBSCRIBER AND PERSONNEL OF UNDERWATER FACILITY (EMBODIMENTS) Russian patent published in 2019 - IPC H04R1/44 H04M9/08 

FIELD: physics.

SUBSTANCE: invention relates to acoustics. Device for electric communication between external subscriber and personnel of underwater facility includes external subscriber communication unit connected by cable of required length to sealed interfacing unit, which interacts with sealed stationary unit. Stationary unit is installed on outer side of underwater facility, rigidly fixed on it and connected by tight cable to its network of GHS. Communication unit can be used by the operator in the surface position of the object, as well as with the participation of the diver, in the submerged position of the object, wherein the communication unit can be either under the diving suit, or on the rescue boat, or on the rescue submarine. Device has a simplex wired voice path and a "transmit-receive" direction selection circuit. Speech path comprises an inductive connector, and the control circuit comprises magnetic interaction elements: an electromagnet and, for example, a reed contact. Parts of induction connector, as well as steam containing electromagnet and reed relay, can be articulated and disassembled both in surface and underwater position.

EFFECT: technical result is enabling uninterrupted communication of a diver with personnel of an emergency submarine.
