Title: ULTRASOUND TRANSDUCER ASSEMBLY AND MOTOR VEHICLE HAVING AN ULTRASOUND TRANSDUCER ASSEMBLY
Abstract:
The invention relates to an ultrasound transducer assembly (18), comprising at least one transducer element (23), a membrane (22), and at least one resonance body (20), wherein the ultrasound transducer assembly (18) is designed to transmit and/or to receive ultrasound signals, wherein the resonance body (20) is coupled to the membrane (22) at an end face (24) and wherein the at least one transducer element (23) is coupled to a lateral surface (26) of the resonance body (20) in such a way that the at least one transducer element and the resonance body have a common interface. The invention further relates to a method for production and to a motor vehicle having such an ultrasound transducer assembly (18), wherein the membrane (22) of the ultrasound transducer assembly (18) is formed by an outer skin of a bumper, of a side mirror, or of a door section and the one or more transducer elements and resonance bodies (20) are arranged in such a way that the one or more transducer elements and resonance bodies are concealed behind the outer skin.
