FIELD: plated piezoelectric electro-acoustic transformers, used as hydrophone.
SUBSTANCE: piezoelectric electro-acoustic transformer contains two bimorph piezoelectric elements, each one of which consists of metallic and piezo-ceramic plates, metallic base, including tubular element and two circular element, sound duct in form of circular resilient rubber element and input for connecting electric signal to generator. Circular elements of the base are provided with circular shelves and hermetically connected to rubber element. External cylindrical surface of the rubber element is in acoustic contact with working substance.
EFFECT: increased reliability of device with preservation of its high sensitivity.
