Paper Abstract

One of our latest developments regards the achievement of an omnidirectional acoustic transducer able to work in marine environment in a wide band of frequency. Our research has involved allowing a fairly linear variation of the impedance active component. This paper presents some aspects concerning the effective achievement of the acoustic transducer and the compensation of the impedance reactive component in order to obtain a maximum transfer of power. The acoustic transducer have a specific construction and are made of PZT-type piezoelectric ceramic obtained in laboratory. Some essential aspects of the measurement methodology and the results obtained are also addressed.
