摘要： The invention relates to an arrangement comprising a vehicle component (1) and at least one electroacoustic transducer, particularly an ultrasonic transducer (2), which is disposed on an internal face (1c) of an outer wall (1a) of the vehicle component (1). The electroacoustic transducer (2) encompasses a pot-type housing (2a) in which a piezoelectric ceramic member (23) is arranged. The pot-type housing (2a) is provided with a bottom area (21) that is fixed to the internal face (1c) of the outer wall (1a) of the vehicle component (1). The invention also relates to an arrangement comprising a vehicle component and an electroacoustic transducer which is removably fixed to the internal face (1c), an acoustic coupling element (4, 5) being placed between the internal faces (1c) and the transducer.
