Abstract

The invention discloses a multimode broadband circular array transducer, which comprises a piezoelectric composite material cambered base array, a decoupling material, a back lining, a shell, a matching layer, a water sealing joint and a cable, wherein the piezoelectric composite material cambered base array is formed by uniformly arranging a plurality of piezoelectric composite material base elements; the decoupling material is filled between the piezoelectric composite material base elements, so that a circular sensitive element is formed; the back lining is tightly attached to the inner side of the circular sensitive element; the shell supports and encircles the sensitive element and the back lining; the matching layer is poured on the outer side of the sensitive element; electrodes are arranged on the upper surfaces and the lower surfaces of the piezoelectric composite material base elements, so that positive electrodes and negative electrodes are led out by wires; wire holes are formed in the back lining, so that the wires pass through the wire holes; a wire outlet is formed on the shell; the water sealing joint seals the wire outlet; and the wires are connected with the cable in the water sealing joint. The transducer has the characteristics of high frequency, high sensitivity, broadband and large directive opening angle.

Description

technical field

[0001] The invention belongs to the technical field of underwater acoustic detection, and in particular relates to a transducer which utilizes the piezoelectric effect of a piezoelectric composite material of a broadband transducer to transmit and receive underwater acoustic signals to realize underwater detection, and can be widely used in underwater communication, Detection, target positioning, tracking, etc., are important components for the use of sonar. Background technique

[0002] The underwater acoustic transducer is a device that converts sound energy and electrical energy into each other. Its status is similar to that of an antenna in radio equipment, and it is a key device for transmitting and receiving sound waves underwater. Underwater detection, identification, communication, as well as marine environment monitoring and the development of marine resources are inseparable from underwater acoustic transducers. Transducers can be divided into tran...
