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).
Claims24
An acoustic transducer unit, in particular for in-ear headphones, wherein:
- the acoustic transducer unit has an electrodynamic acoustic transducer comprising a first membrane,
- the acoustic transducer unit has at least one MEMS acoustic transducer comprising a second membrane,
- the acoustic transducer unit comprises an acoustic-guiding element, in particular an acoustic-guiding tube, and
- the acoustic-guiding element projects beyond the first membrane and/or is adapted as an extension that projects beyond the first membrane.
An acoustic transducer unit, in particular for in-ear headphones, having an electrodynamic transducer comprising a first membrane, having at least one MEMS acoustic transducer comprising a second membrane, and having an acoustic-guiding element, in particular an acoustic-guiding tube, wherein the acoustic-guiding element projects beyond the first membrane and/or is adapted as an extension that projects beyond the first membrane, and
- having a circuit board adapted such that a first rear volume of the electrodynamic acoustic transducer is open, and/or such that said circuit board closes a second rear volume of the MEMS acoustic transducer.
An acoustic transducer unit comprising:
- an electrodynamic acoustic transducer comprising a first membrane, and
- at least one MEMS acoustic transducer comprising a second membrane, and
- at least one microphone, by means of which at least the acoustic waves and/or ambient noise that can be generated by the electrodynamic acoustic transducer can be detected.
