    Abstract: An active noise reduction earphone. The earphone includes structure for positioning and retaining the earphone in the ear of a user without a headband, active noise reduction circuitry including an acoustic driver with a nominal diameter greater than 10 mm oriented so that a line parallel to, or coincident with, an axis of the acoustic driver and that intersects a centerline of the nozzle intersects the centerline of the nozzle at angle θ>±30 degrees. A microphone is positioned adjacent an edge of the acoustic driver. The earphone is configured so that a portion of the acoustic driver is within the concha of a user and another portion of the acoustic driver is outside the concha of the user when the earphone is in position. An opening coupling the nozzle to the environment includes impedance providing structure in the opening.

    Abstract: An earphone includes a first acoustic chamber with one or more of a reactive element and a resistive element for acoustically coupling the first acoustic chamber with an environment external to the earphone. The earphone includes an acoustic transducer and a second acoustic chamber separated from the first acoustic chamber by the acoustic transducer. A housing supports the earphone from the concha of a wearer's ear and extends the second acoustic chamber at least to an entrance of an ear canal of the wearer's ear. A port acoustically couples the first and second acoustic chambers.

    Abstract: In an active noise reducing headphone, a signal processor applies filters and control gains of both the feed-forward and feedback active noise cancellation signal paths. The signal processor is configured to apply first feed-forward filters to the feed-forward signal path and apply first feedback filters to the feedback signal path during a first operating mode providing effective cancellation of ambient sound, and to apply second feed-forward filters to the feed-forward signal path during a second operating mode providing active hear-through of ambient sounds with ambient naturalness.
