A high-power deep-water broadband transducer

Abstract

The invention relates to a high-power deep water broadband transducer, and belongs to the technical field of underwater acoustic transducers. In the transducer: a screw hole is formed in the middle of a middle mass block, a screw with threads on two ends penetrate through the screw hole, and horn heads and a piezoelectric ceramic crystal pile are connected with the middle mass block; the middle mass block is located at the middle of the screw, an even number of piezoelectric ceramic wafers are symmetrically distributed on the left and right sides, the two horn heads are symmetrically distributed on the left and right sides of the piezoelectric ceramic crystal pile and are located on the two ends of the screw, the tails of the horn heads are in threaded connection with the end parts of the screw, and the opening is outward; a cable is connected from the middle mass block; a piezoelectric ceramic circular ring transducer is respectively embedded at each horn head and is connected with the horn head, the piezoelectric ceramic crystal pile and the middle mass block through connecting pieces. The transducer expands the working bandwidth of the transducer while increasing the transmitting power, and realizes high-power deep water broadband transmission.

Description

technical field [0001] The invention relates to a high-power deep-water broadband transducer, in particular to a broadband high-power transducer that can be used in large-depth waters, and belongs to the technical field of underwater acoustic transducers. Background technique [0002] With the development of science and technology and the changes of human society, the strategic significance of the ocean is increasing day by day. And the resources on land are limited, and there are abundant resources in the ocean. In sea water, the propagation attenuation of sound waves is much smaller than that of electromagnetic waves. Therefore, the detection and development of the ocean is inseparable from the use of underwater acoustic equipment. The underwater acoustic transducer is a device that emits and receives sound waves and is the basic component of underwater acoustic equipment. The attenuation coefficient of low-frequency sound waves is relatively small, and the long-distanc...

Problems solved by technology

The longitudinal vibration transducer is a safe and reliable transducer, but its operating bandwidth is relatively narrow, and its size is often large when it works at low frequencies

The Helmholtz transducer is a transducer combined with a cavity and a short tube. The fluid in the cavity vibrates and radiates out through the short tube to achieve low-frequency emission. Because of the overflow structure, it is a transducer that can be used in large Transducers that work in deep sea areas, but the neck of the short tube has a small radiation area, which will produce a higher Q value and a narrower working bandwidth
