Abstract
The invention relates to an acoustic transducer unit (1), in particular for in-ear headphones, having an electrodynamic acoustic transducer (2) comprising a first membrane (10), preferably with a membrane perforation (42), and having at least one MEMS acoustic transducer (3) comprising a second membrane (30). According to the invention, the acoustic transducer unit (1) comprises a circuit board (58) adapted such that a first rear volume of the electrodynamic acoustic transducer (2) is open and/or closes a second rear volume of the MEMS acoustic transducer (3). The invention further relates to an electronic component and to the use of an acoustic transducer unit.
