The main objective of this work is to take traditional high-power, low frequency transducers and miniaturize them to expand the operating range, reduce fabrication costs, and improve performance. This effort began with the development of the "cymbal" and "moonie" miniature flex-tensional transducers. This project improved upon the cymbal design, explored modifications and developed new designs based on other low-frequency technology, such as the hollow sphere and more complex flex-tensionals miniaturized ...
