摘要：
The inventive ultrasonic transducer (1) has a pot-shaped housing, the bottom surface of said housing being partly configured as an oscillating membrane (3). A stabilising ring is provided on the exterior surface of the wall of said pot-shaped housing. Said stabilising ring (6) gives the housing greater rigidity and restricts the ultrasonic oscillation essentially to the base of the pot shape (3) which forms the oscillating membrane. The propagation and reception beam of the ultrasonic waves can be shaped further by means of an additional sound-directing device (7) located in the area of the oscillating membrane (3).

（3）根据本发明，超声换能器（1）设置有一个杯状外壳，所述外底表面部分形成作为振荡膜。 在罐状壳体的壁的外侧，稳定环（6）被提供，这使壳体的较大的刚度和基本上限制在底部锅（3）作为振荡膜的超声波振动。 通过在振动膜（3）的区域中的噪声逆变器（7）的附加装置，超声波的传播与接收波瓣是进一步延展性。
