Linear electroacoustic antenna for low frequency underwater reception-transmission

摘要

The antenna includes a number of electroacoustic transducers (31), each having electroacoustic motors (10), piezoelectric elements and receiver elements (14A). The transducers are equally spaced inside an outer sleeve holder (28). A supply device (43) is disposed next to the outer sleeve (28) for supplying acoustic frequency electric signals. The spacing between the transducers is maintained by assembly cables (29). At least one connection device is disposed at the end of the outer sleeve for permitting mechanical and electrical connection to the supply device. Each electric cable connection device (24) is connected by electric conductors to the electroacoustic transducers. The assembly has a fluid filling (32) between the transducers, and mating cable end connectors, to connect to an identical unit or a receiver module unit.
