Abstract (en)

The transducer has a transmitter emitting ultrasonic waves, and a receiver receiving the ultrasonic waves. A transducer housing (15) is made of soft material, which forms a unit for body sound isolation. The housing has a groove (20) in which a piezoelectric element (17) is engaged. The housing exhibits the form of a sleeve with a front sided opening, which is closed with the piezoelectric element. An adjusting layer (19) is engaged with the piezoelectric element in the groove of the transducer housing.
