HYDROACOUSTIC DEVICE Russian patent published in 2018 - IPC H04R1/44 

FIELD: acoustics.

SUBSTANCE: invention relates to receiving devices and the transmission of hydroacoustic signals designed to convert hydroacoustic signals into electrical signals during reception and electrical signals into hydroacoustic signals during transmission. Apparatus comprises: converter for oscillating the fluid medium and electrical signals, adapted to receive and / or transmit hydroacoustic signals; at least one printed circuit board, connected to a commutation cable; body hydroacoustic device, formed by the outer surfaces of said transducer, at least one board and covering all of these surfaces with a waterproof material, providing transmission of hydroacoustic oscillations, wherein the converter and the at least one printed circuit board are connected in such a way, to form an internal space within the housing; radiator ensuring the contact of the internal space with the external environment and removing heat from said converter and at least one printed circuit board into an external environment.

EFFECT: technical result is the creation of a hydroacoustic device with a simplified design and increased reliability.
