Abstract

Transducer consists of at least two elementary half-wave emitters, each contg. at least two piezoelectric discs prestressed between two metal anvils; and the two emitters are coupled together at the antinodes of their amplitude to form one wavelength. The polarities of the discs in one emitter are pref. inverted w.r.t. the discs in the other to obtain a push-pull effect. Central anvil, i.e. the half wavelength, pref. consists of a single metal piece, esp. a metal bar with a profile influencing the amplitude. This transducer will emit power up to 4000 watts.
