    Abstract: A headphone including a circumaural or supra-aural ear cup having an ear cup housing wall which forms an interior chamber within the ear cup. A transducer is positioned within the interior chamber for producing an acoustic output to a user and an active noise control assembly positioned within the interior chamber. The active noise control assembly including a reference microphone, the reference microphone is acoustically coupled to a plurality of reference input ports spaced around the ear cup housing wall such that a sound input from each of the different spacial locations around the ear cup housing wall is received by the reference microphone and acoustically summed to provide a reference audio signal indicative of the sound input at the different spacial locations. The headphone further including a processing circuit operable to generate an anti-noise signal from the reference audio signal.

    Abstract: Embodiments described herein may take the form of a textile product having one or more regions of reduced density. These reduced density volumes may form one or more features in the product. For example, the reduced density volumes may have better acoustic transmission properties, optical transmission properties, flexibility, and the like. Sound transmission may be enhanced not only in terms of clarity, but also overall range. That is, certain audio frequencies that the textile may normally block when in an unaltered state may pass through a textile having reduced density or reduced density regions.

    Abstract: Intra-concha earphones are disclosed. In an embodiment, an intra-concha earphone includes a housing having a rear space divided into a back volume, a bass duct, and a vent chamber between a driver and a rear wall. The vent chamber may be acoustically coupled with the back volume through both an acoustic port and the bass duct. Furthermore, the vent chamber may be acoustically coupled with a surrounding environment through a vent port, which may be a sole acoustic opening in the rear wall. Thus, sound emitted by the driver may propagate through the acoustic port and the bass duct to meet in the vent chamber before being discharged through the vent port to the surrounding environment. Other embodiments are also described and claimed.
