Sonar transducer housing

摘要: A solid block of material has an outer surface shaped to be streamlined, or otherwise present little flow resistance within a liquid medium; the base, and inner which surrounds transducer elements, entire volume between thereof elements being homogeneous throughout is permeable sound waves created by element, having specific gravity similar that medium propagating therethrough at velocity substantially propagation through liquid, located distance large with respect wave lengths propagated material. To make this transducer, mold provided desired exterior outline then form inserted therein elastic poured into permitted harden housing.
