摘要： An ultrasonic transducer device includes an ultrasonic element array and a common electrode wiring. The ultrasonic element array has three ultrasonic element rows with each of the three ultrasonic element rows including a plurality of ultrasonic elements arranged along a first direction and electrically connected to each other. The three ultrasonic element rows are arranged along a second direction intersecting with the first direction. The common electrode wiring is configured and arranged to supply a common voltage to at least one of the three ultrasonic element rows. The common electrode wiring extends in the first direction and is arranged between two of the three ultrasonic element rows positioned on outer sides among the three ultrasonic element rows with respect to the second direction.

摘要： A sonic or ultrasonic transducer, which is embodied as a radial oscillator. So that the sonic or ultrasonic transducer can be used at high temperatures, a matching layer is located between the radial oscillator and the atmosphere into which the ultrasonic signals are transmitted The matching layer is made from a material that has a dimensional stability up to a temperature which lies above the temperature at the installation location of the sonic or ultrasonic transducer. Furthermore, the matching layer is selected such that its material-specific coefficient of thermal expansion is greater than that of the materials of a piezoelectric unit and a coupling ring, and that the modulus of elasticity of the material of the matching layer is at least one order of magnitude smaller than that of the piezoelectric unit and/or the coupling ring.
