METHOD AND DEVICE OF SONAR TELEPHONE COMMUNICATION OF DIVERS (EMBODIMENTS) Russian patent published in 2018 - IPC B63C11/26 H04B13/02 

FIELD: communication equipment.

SUBSTANCE: invention relates to the underwater communication equipment, in particular to the means of communication of divers, and can be used for communication of divers when working with each other, or with an accompanying vessel or onshore station. Method for the divers' sonar telephone communication is proposed, which includes the transformation of the diver's speech by a microphone into an electrical signal from one transmitting-receiving station for sonar telephone communication of divers, its amplification, speech recognition and transformation into a text message, coding and modulation of a signal with its subsequent emission in the form of a sonar signal into an aqueous medium, reception of the sonar signal by another transmitting-receiving station for sonar telephone communication of divers, its transformation into an electrical signal, amplification of its amplitude with subsequent demodulation and decoding with receiving a text message, synthesizing of a voice message on its basis with transmission to the phone. Embodiments of the transmitting-receiving station of sonar telephone communication of divers are also proposed.

EFFECT: technical result consists in increasing the reliability and quality of communication through the sonar channel.
