The invention relates to a converter unit comprising an ultrasonic transmission element having: a transmission surface for transmitting an ultrasonic vibration to a tool that can be attached to the transmission surface, or to a material that is in contact with same, in a longitudinal direction along a longitudinal axis of the ultrasonic transmission element; and at least one ultrasonic transducer for generating an ultrasonic vibration with a propagation direction that is not oriented along the longitudinal direction, wherein the converter unit has an ultrasonic natural frequency. In order to provide a converter unit comprising an ultrasonic transmission element having: a transmission surface for transmitting an ultrasonic vibration to a tool that can be attached to the transmission surface, or to a material that is in contact with same, in a longitudinal direction along a longitudinal axis of the ultrasonic transmission element; and at least one ultrasonic transducer for generating an ultrasonic vibration with a propagation direction that is not oriented along the longitudinal direction, wherein the converter unit has an ultrasonic natural frequency by means of which a high vibration energy can be generated, according to the invention, the ultrasonic transducer is arranged in the propagation direction in a region of ± λ/4 about the longitudinal axis of the ultrasonic transmission element, where λ is the wavelength of the vibration belonging to the ultrasonic natural frequency. |
