    摘要： An apparatus comprising: a first acoustic chamber (112) including a reactive element (122) and a resistive element (124) in parallel, a second acoustic chamber (114) separated from the first acoustic chamber by an acoustic transducer (116), a housing to support the apparatus from the concha of a wearer's ear and to extend the second acoustic chamber into the ear canal (12) of the wearer's ear, wherein the housing includes a nozzle (126) extending the second acoustic chamber into the ear canal of the wearer's ear, wherein the nozzle ends in an opening, and a screen damper (118) with a hole (128) in it across the opening, wherein the screen damper with the hole in it provides damping of the higher frequency resonances, though not as much as a screen without a hole, but substantially increases low frequency output.

    摘要： A method and apparatus for increasing phase margin in a feedback circuit of an active noise reduction headphone. The method includes providing an acoustic block comprising an acoustic driver comprising a voice coil mechanically coupled along an attachment line to an acoustic energy radiating diaphragm, the acoustic block further comprising a microphone positioned along a line parallel to an intended direction of vibration of the acoustic diaphragm and intersecting the attachment line, the acoustic block characterized by a magnitude frequency response compensating the magnitude frequency response by a compensation pattern that has a positive slope over at least one spectral range above 10 kHz.

    摘要： An improved cushion for use on a headset has a thin front skin (11) formed with a circumferential groove (16). A thin flexible ring (15) is attached to the circumferential groove. A flexible rear skin (14) supports a foam ring (13) and is sealed to the front skin so as to form a gel space. Structure, such as a retaining ring (18) and mating holes and pins (17), attaches the cushion to the headset in use.

    摘要： A circumaural noise reduction headset earcup 58 has, an enclosure 12 with walls separating an interior of said enclosure from the exterior of the earcup 58. A driver 18 with a diaphragm 21 is provided. A port 16 connects the interior and the exterior of the earcup 58, and has a mass that coacts with the compliance of the enclosure 12 to establish a resonant circuit having a resonance at a resonant frequency. An acoustically resistive opening 17 connects the interior and the exterior of said earcup 58 in parallel with the port 16.

    摘要： 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.
