Appl. No.:

08/261802

Inventors:

Roman Sapiejewski - Boston MA

Assignee:

Bose Corporation - Framingham MA

International Classification:

A61F 1106

US Classification:

381 716, 381309, 381371, 381372, 381373, 381375

Abstract:

A supra aural headphone including an earphone that includes a shell body, a cushion mounted on the shell to thereby define an internal cavity behind the cushion, and an acoustical driver mounted within the internal cavity to reproduce sound for the user when driven by an audio signal. The cushion has a passageway extending therethrough which acoustically connects the internal cavity with a users ear cavity when the cushion is resting on the users ear while being worn by the user. The internal cavity has a total volume that is larger than about 10 cubic centimeters, and the driver is mounted in such a way as to avoid obstructing the passageway.

International Classification:

G10K 1116

US Classification:

381 716, 381 74, 381371, 381372, 381 711

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.

International Classification:

H04R 2500

US Classification:

381380, 381370, 381371, 381382

Abstract:

An in-the-ear earphone which is placed on a users ear including a cushion and a shell body defining an internal cavity. The shell body has an extended portion shaped and sized to fit into a concha of the users ear. The extended portion includes an aperture at an end thereof which aligns with the users ear when the earphone is being worn by the user. The extended portion defines a passageway extending from the aperture to the internal cavity. The cushion covers at least part of the extended portion of the shell body and has an opening aligned with the aperture.

US Classification:

381374, 381370, 381 74

Abstract:

A noise reducing headset has one or more of the following features: (a) pair of earcups each seated in a yoke assembly mechanically coupled by a headband enclosing a flat spring formed with a slot that runs the length of the spring accommodating electrical wires electrically interconnecting electrical elements in the earcups, (b) each earcup having active noise reducing circuitry, (c) each earcup including a loudspeaker driver located off center in the earcup to allow an internal cavity inside each earcup to accommodate a loudspeaker driver, a microphone and an electronic printed circuit board and one of a battery and plug assembly, (d) one of the earcups accommodating a detachably secured plug assembly having a sensitivity switch covered by the earcup when the plug assembly is fully seated in the earcup, (e) the other earcup having a battery door that may be opened to allow insertion and removal of the battery and covered by a yoke assembly when the headset is worn by a user with the battery fully seated in the earcup.

International Classification:

H04R 25/00

US Classification:

381382, 381370, 381371, 381374

Abstract:

An earphone includes a first acoustic chamber including a reactive element and a resistive element in parallel, a second acoustic chamber separated from the first acoustic chamber by an acoustic transducer, and 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 of the wearer's ear. A cushion includes a first material and a second material and is formed into a first region and a second region. The first region defines an exterior surface shaped to fit the concha of a human ear. The second region defines an exterior surface shaped to fit the ear canal of a human ear. The first and second regions together define an interior surface shaped to accommodate an earphone. The first material occupies a volume adjacent to the interior surface. The second material occupies a volume between the first material and the first and second outer surfaces.

Abstract:

Power is delivered from a power source in a head-mounted device to a separate accessory that is coupled to the head-mounted device. Power and signals are delivered on a common conductor that couples the head-mounted device to an accessory. One or both of the head-mounted device and the accessory are configured based on the signals. Power may be received at an accessory from the head-mounted device through a dedicated power conductor. Power may be delivered from a power source in a portable accessory to a head-mounted device that is coupled to the portable accessory and uses the power for circuitry in the head-mounted device that delivers audio to a user.
