Abstract
A flexural disk transducer is located in a shell or enclosure primarily for underwater use. Compression chambers adjacent to the transducer capture sound from bands on the disk and waveguides are used to direct the sound forward along a single propagation axis. An acoustic delay line is built into one waveguide to compensate for phase differences between the bands.
