Abstract

An ultrasonic transducer has a pot-like housing with an annular wall and with a bottom surface serving as diaphragm. A piezo-element which is connected with connection lines is arranged at the inner side of the bottom surface. The edge remote of the bottom surface is surrounded by a decoupling ring which is formed as a holder for the connection lines.
