EXPLORATION OF MULTI-ELEMENT BROAD BAND TRANSDUCER.

Abstract

The problem is defined as one whereby a broad band transducer is obtained by the use of many small elements, having normal values of mechanical Q, in an array. The technique employed here is one of selecting a set of dissimilar transducer elements and spatially arranging them throughout the array in various distributions. These distributions are selected on the basis of the individual air-resonant frequency of the elements. The behavior of this array, for several frequency distributions, with respect to the element's velocity, radiation load, radiated power, efficiency and transmitting response is presented. The results do indicate the possibility of designing a broad band transducer by multi-element array with some sacrifice in efficiency. (Author)
