  • Patent number: 10327062
    Abstract: A headphone includes a housing defining an enclosed volume, an electro-acoustic transducer dividing the enclosed volume into a front volume and a rear volume, a first port in the housing coupling the front volume to an ear canal of a user, a second port in the housing coupling the front volume to space outside the ear, a third port in the housing coupling the rear volume to space outside the ear, and an ear tip configured to surround the first port and seal the ear canal from space outside the ear. The second port has a diameter and a length that provide an acoustic mass with an acoustic impedance with a high reactive component and a low resistive component.

  • Patent number: 10074354
    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.

  • Patent number: 10034086
    Abstract: A headset includes at least one ear cup having front and rear cavities separated by a driver. The cup includes a pressure equalization port coupling the front cavity to space outside the cup, the pressure equalization port having a cross-sectional area greater than 2 mm2 and being significantly longer than it is wide, providing a principally reactive acoustic impedance, such that the pressure response of the front cavity including the port to signals input via the driver may be effectively linear over a wide range of pressure levels within the front cavity.

  • Patent number: 8675885
    Abstract: A headset includes first and second earcups each having a front opening adapted to be adjacent to a respective ear of a user and including an electroacoustic transducer, a headband coupled to each of the earcups, and an active noise reduction circuit coupled to the electroacoustic transducers. The headband is configurable between at least two configurations that each press the earcups against the head of the user with different amounts of force. The active noise reduction circuit is configured to determine which of the at least two configurations the headband may be configured in, to provide a different amount of noise reduction when the headband may be configured in each of the different amounts of force, and to automatically transition between the different amounts of noise reduction in response to a change in the configuration of the headband between the at least two configurations.

  • Patent number: RE45151
    Abstract: A headset has an earcup with front opening adjacent to an annular cushion formed with a plurality of openings facing the inside of the earcup that acoustically couples the earcup volume to the cushion volume. A driver is seated inside the earcup with a microphone adjacent to the driver. Active noise reducing circuitry intercouples the driver and microphone. An acoustic load that may comprise a wire mesh resistive cover and/or air mass adjacent the microphone is constructed and arranged to reduce the effect of resonances in the earcup volume.
