Aspects describe an in-ear audio output device. The in-ear audio output device includes an acoustic chamber defined by an earbud housing shaped to fit in the lower concha of an ear of a wearer of the in-ear audio output device, the earbud housing comprising: a resistive port located on a first side of the earbud housing creating an opening in a wall of the earbud housing and a first feedforward microphone located on a second side of the earbud housing, the second side substantially opposite the first side of the earbud housing; and a stability band. The stability band includes at least one attachment feature that couples the stability band to the earbud housing and a first side substantially opposite the attachment feature that only partially covers the resistive port when the in-ear audio output device is positioned in the ear of the wearer.

Aspects describe air flow relief features in the cosmetic surface of the housing of an in-ear audio output device. Due to design constraints based, at least in part, on the limited space available in the acoustic chamber and ear geometry, ports coupling the acoustic chamber with an area outside the housing are susceptible to full blockage when placed in-ear. Air flow relief channels for ports, extending from the port aligned in the concha cymba, over the helix crus, to the cymba cavum minimize complete blockages of the port as compared to current designs.

Earbud

An earbud with a housing comprising a housing outer wall and an electromagnetic radiation-transmissive lens in the housing outer wall. The housing outer wall and the lens are co-molded.

Earphone

An apparatus includes a printed wiring board (PWB) that defines an aperture. A microphone is mounted on the PWB such that the aperture provides an acoustic path to the microphone. An acoustic interface member defines a cavity that is acoustically coupled to the microphone via the aperture. A first gasket between the printed wiring board and the acoustic interface member forms an acoustic seal. A housing is included, and a second gasket is disposed between the acoustic interface member and the housing to form an acoustic seal. An acoustic chamber is defined by a sealed volume that extends from a first (bottom/inner) surface of the housing down to a junction between the microphone and the PWB. The housing defines apertures which provide an acoustic path between a region external to the housing and the acoustic chamber. The acoustic chamber and the apertures in the housing form a Helmholtz resonator.

Microphone cavity

A portable audio system includes a housing. A docking cradle includes a connector that is electrically coupled to the electronic audio circuit. The docking cradle is mechanically coupled to the housing such that the docking cradle is capable of being rotated horizontally between an open position in which the connector is external to the housing and a closed position.
