ULTRASONIC VIBRATION SYSTEM

摘要

FIELD: physics. ^ SUBSTANCE: ultrasonic vibration system for reception and emission of ultrasonic vibration within broad band designed on basis of multimode multifrequency structure with amplitude-frequency characteristic adjusted within demanded frequency range. Ultrasonic vibration system is functional radiating element designed as spindle or hollow cylinder, face surfaces of which are in acoustic and mechanic mode connected with two piezoelectric transducers having underfrequency pads with step-adjustable length. ^ EFFECT: provides adjustment of amplitude-frequency characteristic due to combination of lengths and areas of piezoelectric transducer stages. ^ 3 dwg
