A broadband cluster transducer; based on barrel-stave flextensional transducer technology; was designed; built; and tested in air and seawater at Defence R&D Canada-Atlantic. The design goal was to develop a transducer that exhibited a transmitting voltage response of greater than 120 dB//1 μPa-m/V from 1 to 7 kHz and have the potential for beamsteering. Six orthogonal piezoceramic-driven class I barrel-stave transducer elements mounted on a central manifold were wired separately; allowing each to be driven individually or in combination with the other elements. The resonance modes under the following drive conditions were determined from in-air conductance measurements: each of the six elements excited individually as mass-loaded class I flextensionals; three collinear pairs driven separately as class III flextensionals; and all six elements driven in phase simultaneously. The fully-driven cluster was found to have a transmitting voltage response of greater than 120 dB//1 μPa-m/V from 800 Hz to more than 10 kHz and its topology is amenable to beamsteering that is yet to be characterized. © 2009 Acoustical Society of America;
