Zusammenfassung: | An in-ear earphone (40) comprising: a body (42) configured to be placed at the entrance to or to be inserted at least in part into the auditory canal of a user's ear, the body (42) housing an electro-acoustic driver (2) and defining a passageway structure (50) extending from the electro-acoustic driver (2) to an opening (48) in an outer surface of the body (42) for allowing sound generated by the electro-acoustic driver (2) to pass into the auditory canal of the user's ear; characterised in that the passageway structure (50) comprises: a flow divider section (52) positioned to receive forward-radiated sound from the electro-acoustic driver (2); an output passageway (3) extending from the flow divider section (52) to the opening (48) in the body (42); and an unvented enclosure (41) in fluid communication with the flow divider section (52) and operative to provide an acoustic impedance in parallel to the output passageway (3). |
