An ultrasonic transducer system includes at least one transducer element, a diaphragm, and at least one resonance body, the ultrasonic transducer system being configured for transmitting and/or receiving ultrasonic signals, the resonance body being coupled at an end face to the diaphragm and the at least one transducer element being coupled to a lateral surface of the resonance body so that the at least one transducer element and the resonance body have a shared interface. Also described is a method for the manufacture and to a motor vehicle having an ultrasonic transducer system of this type, the diaphragm of the ultrasonic transducer system being formed by an outer skin of a bumper, a side mirror, or a door section, and the transducer element(s) and resonance bodies being situated concealed behind the outer skin.
