摘要

Ultrasound transducer comprises a U-shaped pot with a hollow cylindrical wall (4) and an end on the front side forming the transducer face (5) and an electromechanical transducer arranged on the inner side of the transducer face forming an ultrasound bending transducer with the face. The outer side of the transducer face is connected to a layer (3) covering the ultrasound transducer on the front side. The thickness of the pot wall to the pot diameter is 0.2: 2. Preferred Features: The transducer has a reinforced pot wall and a damping ring (11). The width of the annular gap (9) between the pot wall and the damping ring is maximum 1 mm.
