摘要

Abstract: It is difficult to do significant work on transducers in an academic or small-shop setting since the machinery required for the fabrication of the micro-sized elements is expensive, and the needed human expertise takes a long time to acquire. The expense of preparing for prototype production must be committed even before the design has been tested. This paper discusses a means to allow fabrication of low-frequency models of high-frequency transducers in the average academic laboratory or model shop - without requiring exotic saws, presses, etc., for preliminary evaluation of the design. These models will have the added advantage that they can be more realistic models of actual transducers than present computer models. In addition, we show that acoustic fields can be scaled so that field models of scattering and propagation can be used to investigate these effects. !6
