Abstract

Zur verbesserten Einkopplung von Schallwellen in das Innere eines Behälters ist an der Außenwand (1) des Behälters (2) ein Schallkopf (3) ausgebildet, der ein außen an dem Behälter (2) befestigtes und zu dem Behälter (2) hin offenes Gehäuseteil (4) aufweist. In dem Inneren des Gehäuseteils (4) sind eine Piezoscheibe (5) und eine diese gegen eine in der Außenwand (1) des Behälters (2) ausgebildete plane Anlagefläche (9) drückende Andruckvorrichtung (10) angeordnet, wobei die Anlagefläche (9) nur in Kontakt mit der Piezoscheibe (5) ist und durch eine umlaufende Nut (21) in der Außenwand (1) des Behälters (2) begrenzt ist.

Figure imgaf001
For improved coupling of sound waves into the interior of a container, a transducer (3) is formed on the outer wall (1) of the container (2), which has a housing part (FIG. 2) attached to the outside of the container (2). 4). In the interior of the housing part (4), a piezoelectric disk (5) and a pressure device (10) pressing against a planar contact surface (9) formed in the outer wall (1) of the container (2) are arranged, the contact surface (9) only is in contact with the piezoelectric disk (5) and is delimited by a circumferential groove (21) in the outer wall (1) of the container (2).
