Experimental Feasibility Study of an Analog Electrical-to-Fluidic Transducer

An approach to the mechanization of an analog electrical-to-fluidic transducer using carrier circuit techniques is described. Design details for a laboratory breadboard model are given along with test results. Mechanical design is based on the use of a bender-type piezoelectric assembly, driven by dc voltage controlled microelectronic oscillators. Several questions, regarding feasibility of the approach such as size of the transducer, electrical input voltage level, and electrical power level are resolved favorably by the results of breadboard model testing. Consideration is given to inclusion of an inverted acoustic horn for signal intensification.
