Amplifier unit for operating a piezoelectric sound transducer and / or a dynamic sound transducer and a sound generating unit

摘要

The invention relates to an amplifier unit for operating a piezoelectric sound transducer (2) and / or a dynamic sound transducer (3), wherein the sound transducers (2, 3) preferably comprise loudspeakers and / or microphones, with at least one audio amplifier (4, 5). According to the invention, the amplifier unit (1) comprises a detection unit (6) by means of which, in particular automated, it can be recognized whether a sound transducer (2, 3) coupled to the amplifier unit (1) is a piezoelectric (2) or a dynamic sound transducer (3) , Furthermore, the invention relates to a sound generation unit (19) with at least one sound transducer (2, 3) and an amplifier unit (1), which amplifies an audio signal and the sound transducer (2, 3) supplies.
