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.

Abstract: A personal listening system has an active noise control (ANC) controller that produces an anti-noise signal. A head worn audio device for a user has a speaker to convert the anti-noise signal into anti-noise, an error microphone, and a reference microphone. The controller uses signals from the error and reference microphones to produce the anti-noise signal in accordance with an adaptive filter algorithm that has an adjustable parameter which changes so as to move the point at which acoustic cancellation occurs from the error microphone and closer to the user's eardrum. Other embodiments are also described and claimed.
