An earpiece with structure for positioning and retaining the earpiece and with structure for sealing against the entrance to the ear canal to provide passive noise attenuation. The positioning and retaining structure engages features of the lateral surface of the ear. The structure for sealing against the entrance to the ear canal includes a conical structure.

Earpiece passive noise attenuating

A positioning and retaining structure for an in-ear earpiece. An outer leg and an inner leg are attached to each other at an attachment end and attached to a body of the earpiece at the other end. The outer leg lies in a plane. The positioning and retaining structure have a stiffness that is greater when force is applied to the attachment end in a counterclockwise direction in the plane of the outer leg than when force is applied to the attachment end in a clockwise direction in the plane of the outer leg. The positioning and retaining structure position an earpiece associated with the earpiece in a user's ear and retains the earpiece in its position.

Earpiece positioning and retaining

A headphone with a headband and at least one earcup. The at least one earcup is movably coupled to the headband by a joint that is structured to allow rotation of the earcup relative to the headband about two mutually perpendicular axes, and translation along one of these axes.

Headphone joint

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.

Earphones

An active noise reduction earphone includes structure for positioning and retaining the earphone in the ear of a user and, 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 &#x3d1;&#x3e;&#xb1;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 and another portion of the acoustic driver is outside the concha.

In-ear active noise reduction earphone

A compliant constrained headband spring for audio headphones includes a headband spring element and a stiffness enhancing element coupled to the headband spring element. The compliant constrained headband spring exhibits a first stiffness in an open position and a second stiffness greater than the first stiffness when closed beyond a predetermined point.
