Paper Title:
Research on Fabrication Techniques and Performance Analysis for 3×3 Cymbal Transducer Array
  Abstract

The single array element of cymbal transducer has a low transmitting power, poor directivity and narrow bandwidth, which however can be improved, even overcome by array forming. First of all, 9 cymbal transducer array elements were designed and made on the basis of the research results obtained in the early stage, and were assembled into a 3x3 array by using a set of stable and reliable array forming techniques developed from the research. The array was shaped by casting with organic silica-gel and then getting cured. The array was tested in air for resonance frequency and equivalent circuit parameters demonstrating the stability of array forming techniques. The array and a single array element were also tested in anechoic water-tank for transmitting, receiving and directivity performances, and the result indicates that, the array forming by elements can strengthen the transmitting power and improve the directivity effect, but may reduce the free-field receiving sensitivity. The research has a great significance to the development of a new super multi-element cymbal array.
