Abstract
Method for providing micro-miniature high efficiency ultrasonic transducer assembly having a diameter of 0.018 inches or less. A transducer is formed from a selected transducer material to provide a cylindrical transducer having front and back sides with a thickness which is one-half of the diameter of the transducer +/-5%. The frequency constant of the material is ascertained. The frequency of operation of the transducer is ascertained by dividing the frequency constant by the thickness of the transducer in mils. The transducer is mounted in a housing and leads are secured to the front and back sides of the transducer.
