Abstract

The design and selection of the transducer array parameters directly affect the performance of the audio directional transmission system. In this paper, the influence of the number of array element, the pitch, the frequency and the deflection angle on the array directivity is analyzed in detail. The relationship between the above parameters and the directivity is obtained by computer simulation and the relationship between the array performance and the actual manufacturing cost of the design. It provided a basis for performance evaluation and optimization design of phased array ultrasonic transducer arrays.
