| الوصف: | Three types of transducers were mathematically modeled to gain knowledge of the potentials and limitations of alternating lead- and ceramic-staved cylinder transducers, curved bender bar transducers, and ribbed-cylinder flextensional transducers. It was determined that bandwidth of alternating lead- and ceramic-staved cylinders can be maximized through careful choice of material composition, ceramic thickness, length-to-diameter ratio, and stave geometry. Analysis of the curved bender bar transducer showed that a small, light-weight, low-power output transducer could be built with an in-air resonance frequency between 100 and 500 Hz. A ribbed-cylinder flextensional transducer is basically a low-frequency narrowband device but modifications can be made to the current design which will lower its first in-air resonance frequency and improve its reliability.
