Research on the directivity of transducer array based on typical array elements

Abstract

In order to analyze the directivity of the array composed of different shape array elements, a line array is made up of the point source, circular, annular and rectangular piston sound source, and the directivity of the array is analyzed by simulation software. The results show that the directivity of line array is influenced by many factors, such as array element spacing, geometric dimensions, array shape, number of array elements, wave number or frequency, etc. When the condition is equivalent, the directivity of the transducer array composed of annular array element is relatively optimal.
