Abstract

Ultraschallwandler (20) mit einem zur Abstrahlung von Ultraschallschwingungen anregbaren piezoelektrischen Wandlerelement (21). Während man bisher den Weg einer Überdimensionierung des Anpassungskörpers (22) in Durchmesser-Richtung betrieb, geht man bei der Erfindung den Weg, durch Anpassung der seitlichen Umfangsfläche des Anpassungskörpers einen effektiven, kleinstmöglichen Durchmesser des Anpassungskörpers (22) zu erreichen.
