Abstract (en)
[origin: WO2014037354A1] The invention relates to an ultrasonic transducer (1) comprising a housing (2) and a piezo element (5). The piezo element (5) is inserted into a cavity (4) of the housing, and the housing (2) is equipped with a covering means (8) which covers the cavity (4). A spring element (6) is arranged between the covering means (8) in the piezo element (5), said spring element applying a spring force onto the piezo element (5), and the covering means (8) has multiple conductor paths which establish a contact through the covering means (8).
