Emission of Sound by a Finite Array of Open Piezoceramic Rings

The emission of sound by finite arrays of open piezoceramic rings, when the input voltages rather than the oscillatory rates at the ring walls are specified, is analyzed. A rigorous method of solution of this problem, allowing for local features of the acoustic field near the ends of the rings is suggested. The acoustic interaction of the rings when operating in multi-ring arrays is analyzed over a wide range of frequency and ring spacings. Both pulsating- and oscillating-ring arrays are analyzed.
