In addition, the transducer unit 1 comprises a diaphragm unit 5, which is coupled to the at least one transducer element 3. With the aid of the diaphragm unit 5, for example, vibrations can be transmitted, as deflections, from the transducer element 3 onto the surrounding air, so that sound is generated and the transducer unit 1 is therefore operated as a loudspeaker. Additionally or alternatively, with the aid of the diaphragm unit 5, sound waves in vibrations can also be detected as deflections, which are converted into an electrical signal by the transducer element 3. The transducer unit 1 can therefore be operated as a microphone. Of course, it does not depend on whether sound deflects the diaphragm unit 5. For example, the transducer unit 1 can also be a pressure or force sensor, and so a medium other than air deflects the diaphragm unit 5, wherein this deflection is converted into an electrical signal by the transducer element 3.

The at least one transducer element 3 is deflectable along a stroke axis H.

The transducer element 3 can comprise, for example, at least one piezoelectric element or piezoelectric actuator, which generates a voltage upon deflection and, itself, deflects upon application of a voltage. In a further exemplary embodiment, the transducer element 3 can also comprise a coil and a magnet. The transducer unit 1 can therefore also be an electrodynamic sound transducer.

The transducer unit 1 can also be any other sensor and/or actuator, however. For example, the transducer unit 1 can be a pressure or force sensor, which ascertains a pressure or a force on the basis of a deflection of the transducer element 3. As an actuator, the transducer unit 1 can also form a pressure or a force.
