Arc array of transducer and preparing method

Abstract

The invention discloses an arc array of a transducer and a preparing method. The preparing method includes the following steps that a ceramic material is attached to a lining; the ceramic material is cut, and a ceramic particle array is obtained; the lining and the ceramic particle array are integrally bent; the bent ceramic particle array is poured; the lining is torn off; electrodes are laid on the ceramic particle array, and weighing control is conducted on the shape of the electrodes. The invention further discloses the arc array of the transducer. The arc array comprises the ceramic particle array with an arc section and the electrodes laid on the inner arc face and the outer arc face of the ceramic particle array. The ceramic particle array is composed of ceramic particles which are even in size and arranged side by side at equal intervals. The arc array of the transducer and the preparing method have the advantages that the preparing technology is simple, consistency is good, the impedance unimodality is good, fluctuations in wave beams are small, and the arc array is suitable for mass preparing.

Description

Technical field: [0001] The invention relates to the technical field of underwater acoustic detection, and more specifically relates to a method for manufacturing an arc array of a transducer and the arc array. Background technique: [0002] Sonar is an electronic device that uses underwater sound waves to detect, locate and communicate underwater targets. It is the most widely used and most important device in underwater acoustics. One of the important ways to improve the performance of sonar is to expand the frequency bandwidth of the transducer, and the typical requirement of the wideband transducer is multi-beam sonar. Among various underwater acoustic detection methods, multi-beam sonar has been widely recognized for its advantages of high detection efficiency, convenient use, and long detection distance. The size of the beam width of the transducer and the inhomogeneity within the beam range directly affect the detection effect of the multi-beam sonar. [0003] The b...

Problems solved by technology

The advantage of the arc-shaped ceramics is that it is easy to manufacture; the disadvantage is that the size of the arc-shaped ceramics is limited by the ceramic manufacturing process, and the application of large-scale and high-power cannot be realized, and the internal coupling vibration of the ceramics is complicated, and the directivity of the manufactured transducer fluctuates bigger

The 2-2 structure arc array adopts several slender ceramic strips arranged in parallel on the arc backing, which has the advantage that it is not limited by the production of ceramic components and can be spliced ​​into an arc array with a large radius of curvature to achieve a large Power emission; the disadvantage is that the high-order length vibration mode of the slender ceramic strip is coupled with the thickness vibration mode, which needs to be avoided during design, and has high requirements for the consistency of the ceramic strip used for splicing. Batch screening is required, and good splicing uniformity of ceramic strips is also required when making transducers
