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 sound transducer (3) comprising a second membrane (30). According to the invention, the acoustic transducer unit (1) comprises a sound-guiding element (16), by means of which sound waves generated by the MEMS acoustic transducer (3) can be guided past the electrodynamic acoustic transducer (2), in particular guided past the first membrane (10) of the electrodynamic acoustic transducer (2).
Claims22
