Patent number: 11818561Abstract: Digital audio signal processing techniques used to provide an acoustic transparency function in a pair of headphones. A number of transparency filters can be computed at once, using optimization techniques or using a closed form solution, that are based on multiple re-seatings of the headphones and that are as a result robust for a population of wearers. In another embodiment, a transparency hearing filter of a headphone is computed by an adaptive system that takes into consideration the changing acoustic to electrical path between an earpiece speaker and an interior microphone of that headphone while worn by a user. Other embodiments are also described and claimed.Type: GrantFiled: November 9, 2022Date of Patent: November 14, 2023Assignee: Apple Inc.Inventors: Ismael H. Nawfal, Joshua D. Atkins, Stephen J. Nimick, Guy C. Nicholson, Jason M. Harlow

Patent number: 8073181Abstract: An electrical equalization module that is second order or higher. The equalization module is used to achieve a desired frequency response for audio headphones. The equalization module includes capacitors or inductors. The equalization module is a bridged-T circuit, parallel RLC circuit, or series RLC circuit.Type: GrantFiled: December 27, 2006Date of Patent: December 6, 2011Assignee: Bose CorporationInventors: Pericles Nicholas Bakalos, Roman Sapiejewski, Jason M.

Patent number: 7916888Abstract: An earphone includes a first acoustic chamber including a reactive element and a resistive element in parallel, a second acoustic chamber separated from the first acoustic chamber by an acoustic transducer, and a housing to support the apparatus from the concha of a wearer's ear and to extend the second acoustic chamber into the ear canal of the wearer's ear. A cushion includes a first material and a second material and is formed into a first region and a second region. The first region defines an exterior surface shaped to fit the concha of a human ear. The second region defines an exterior surface shaped to fit the ear canal of a human ear. The first and second regions together define an interior surface shaped to accommodate an earphone. The first material occupies a volume adjacent to the interior surface. The second material occupies a volume between the first material and the first and second outer surfaces. The first and second materials are of different hardnesses.Type: GrantFiled: June 30, 2006Date of Patent: March 29, 2011Assignee: Bose CorporationInventors: Roman Sapiejewski, William W. Tice, Jason M. Harlow, Ian M. Collier, Kevin P. Annunziato, Pericles Nicholas Bakalos, Michael J. Monahan
