Acoustic Radiation from a Free Flooded Piezoelectric Ring Transducer of Rectangular Cross Section
Abstract
The acoustic radiation from a free-flooded ring transducer of rectangular cross section depends not only on the oscillation of the mean diameter, but on the pulsation of the ring wall and height. On the expansion of the mean diameter a positive pressure is produced on the outer surface while a negative pressure is produced on the inner surface. These two pressures tend to cancel one another. Because of this, the pressure arising from other portions of the ring can not, in general, be neglected. The object of this report is to present a simple model which easily accommodates these modes of vibration which are coupled through the piezoelectric state equations.
