Abstract

The invention relates to the technical field of transducers, in particular to a pressure compensation extremely-low-frequency bending disc transducer which comprises a transmitting assembly A and a transmitting assembly B. The transmitting assembly A and the transmitting assembly B are arranged in a matched mode and are each composed of a cover plate, a piezoelectric ceramic wafer, a plastic ring, a negative electrode soldering lug, watertight rubber and a ring shell which are the same, and the cover plate is arranged on the ring shell. The plastic ring is installed on the cover plate, a plurality of piezoelectric ceramic wafers are evenly distributed on the side face, located outside the ring shell, of the cover plate, the positive electrode faces of the piezoelectric ceramic wafers are attached to the cover plate, the negative electrode soldering lugs are connected with the negative electrode faces of the piezoelectric ceramic wafers, and the watertight rubber is attached to the outer side face of the cover plate in a sealed mode. The watertight rubber covers the piezoelectric ceramic wafer and the joint between the cover plate and the annular shells, the two annular shells are symmetrically sealed and spliced to form the integral disc transducer, the use depth can reach the kilometer level, and meanwhile the transducer has the advantages of being small in size and light in weight.

Description

technical field [0001] The invention relates to the technical field of transducers, in particular to a pressure-compensated ultra-low frequency curved disk transducer. Background technique [0002] The curved disc transducer has the advantage of small size and low frequency emission, but at the same time has the disadvantage of weak hydrostatic pressure resistance, especially when the operating frequency drops to the order of several hundred Hz, its maximum working water depth drops sharply, such as the resonance frequency The 200Hz curved disk transducer has the advantage of small size, and its maximum working water depth is only 50 meters. If its operating frequency is several hundred hertz, the working water depth can still be kept above 300 meters, and its volume and weight will increase to the same level as other types of transducers, completely losing the advantages of low frequency and small size transmission. [0003] In order to maximize its low-frequency advantage...
