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

Various implementations include wearable audio devices configured to record a user's voice without recording other ambient acoustic signals, such as others talking nearby. In some particular aspects, a wearable audio device includes: a frame for contacting a head of a user; an electro-acoustic transducer within the frame and configured to output audio signals; at least one microphone; a voice activity detection (VAD) accelerometer; and a controller coupled with the electro-acoustic transducer, the at least one microphone and the VAD accelerometer, the controller configured in a first mode to: detect that the user is speaking; and record a voice of the user solely with signals from the VAD accelerometer in response to detecting that the user is speaking.

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 retaining member for an earphone includes an outer layer of a first material surrounding an inner core of a second material. The retaining member extends from the earphone, and is curved to generally match the shape the antihelix of a human ear. The second material is harder than the first material, providing a stiffness to the retaining member that causes it to apply an upward and backward force against the antihelix when the retaining member is bent to fit under the antihelix of a particular user's ear.

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.

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.
