Abstract
An ultrasound transducer device with a one-dimensional or two-dimensional array of transducer elements (4.sub.j) has at least one plate-shaped component. This component contains an acoustical attenuation element (3), at one narrow side (3c) of which the transducer elements (4.sub.j) are arranged with piezoelectric oscillation elements and electrodes, as well as an electronic circuit part (17a) and connection leads (10a) between this circuit part and the electrodes. An electrode is arranged at each transducer element (4.sub.j) between its oscillation element and the attenuation element (3), which has a connection part for the connection leads (10a) which leads to a broad side (3a), and a strip-shaped carrier element (14) is connected with the attenuation element (3), with the electronic circuit (17a) located on the one broad side. Cooling channels (20, 21) may be used as a means for cooling the carrier element (14, 14.sub.k). Preferably, two components can form a common partial system (2) of the transducer device.
