Publication number: 20150382100Abstract: 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.Type: ApplicationFiled: April 17, 2015Publication date: December 31, 2015Inventors: Yacine Azmi, Esge B. Andersen, Michael B. Howes, Jonathan S. Aase

Patent number: 9208769Abstract: An adaptive noise-cancelling headphone including an earcup housing having a driver for outputting sound to a user positioned therein. The headphone further including an active noise control assembly. The active noise control assembly may include an ambient microphone capable of detecting an ambient noise outside of the housing and an error microphone capable of detecting an earcup noise inside of the housing. Based on the detected noise, active noise cancellation within the headphone is either enabled or disabled. The headphone may further include a passive noise control assembly. The passive noise control assembly may include an acoustic valve associated with an acoustic vent formed within the earcup housing. The acoustic valve is capable of being modified between an open configuration to decrease sound attenuation and a closed configuration to increase sound attenuation in response to the detected ambient noise so as to improve an acoustic performance of the earcup.Type: GrantFiled: December 18, 2012Date of Patent: December 8, 2015Assignee: Apple Inc.Inventor: Yacine Azmi

Patent number: 9173028Abstract: A system for speech enhancement in a room having a directional lapel microphone arrangement for capturing an audio signal from a speaker's voice; audio signal processor for generating a processed audio signal from the captured audio signal, and an adaptive beamformer unit for imparting directivity to the microphone arrangement provides maximum sensitivity towards the speaker's mouth and minimum sensitivity towards noise sources identified by the beamformer unit. A unit shifts the frequency of components of the audio signal above a frequency threshold value only. A feedback cancelling unit has an adaptive filter and a selection unit which automatically switches between a first mode causing the audio signal to by-pass the adaptive filter and a second mode in which the audio signal is filtered by the adaptive filter. A loudspeaker arrangement generates sound according to the processed audio signal and has plural loudspeakers arranged to form a directional loudspeaker array.Type: GrantFiled: July 14, 2011Date of Patent: October 27, 2015Assignee: Sonova AGInventors: Francois Marquis, Hans-Ueli Röck, Samuel Harsch, Yacine Azmi, Tim Jost
