ULTRASONIC TRANSDUCER

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).
