Patent number: 11587543Abstract: Methods for calibrating active noise-cancelling headphones, including placing the active noise-cancelling headphones on a measuring device; exciting the active noise-cancelling filter; measuring one or more relevant transmission pathways selected from x(n), m(n), and p(n) for feedforward and/or h(n) for feedback; defining at least one goal function for feedforward or feedback; calculating a complementary function for the defined goal function for at least one branch of the active noise-cancelling filter; calculating an impulse response of the complementary function from the measurements of the relevant transmission pathways; approximating operating parameters for the active noise-cancelling filter using the Prony method; and implementing the approximated operating parameters in the active noise-cancelling filter on the signal processor in order to create an approximated complementary active noise-cancelling filter, thereby calibrating the active noise-cancelling headphones.Type: GrantFiled: November 12, 2021Date of Patent: February 21, 2023Assignee: AUSTRIAN AUDIO GMBHInventors: Michael Perkmann, Daniel Wöhrer, Ludwig Kollenz

Patent number: 11189260Abstract: Active noise-cancelling (ANC) headphones in the form of a part of a headset or as in-ear headphones that reduce acoustic adaptation by providing an electrodynamic speaker in a housing with ventilation openings and an acoustically permeable front panel. These components form a module that can be integrated into ANC headphones, permitting its installation in different headphones without customization. The module reacts to a reduction of the impermeability situation in such a manner, that an impedance change of the speaker takes place below 100 Hz. For example, a microphone and electronics with a feedback filter for active noise cancellation can be provided that form a secondary route between speaker and microphone. In a further development, an evaluation unit is provided which detects and evaluates a change in the impedance of the speaker and adapts the feedback loop.Type: GrantFiled: August 14, 2019Date of Patent: November 30, 2021Assignee: AUSTRIAN AUDIO GMBHInventor: Bernhard Pinter

Patent number: 10602280Abstract: A condenser microphone, including at least one diaphragm, at least one electrode assigned to the diaphragm, comprising at least one ring-shaped insulator holding the electrode, comprising at least one diaphragm ring holding the diaphragm, and a holding ring holding the components mentioned. The mechanical and electrical properties of the condenser microphone are improved where the holding ring includes ceramic material. Preferably, the diaphragm ring and/or the ring-shaped insulator also consist(s) of ceramic material. With further preference, the ceramic material is zirconium oxide.Type: GrantFiled: March 22, 2019Date of Patent: March 24, 2020Assignee: Austrian Audio GmbHInventors: Dieter Rapitsch, Christoph Frank, Mathias Balac

Publication number: 20200084535Abstract: In-ear active noise-cancelling (ANC) earphones for which the ANC circuit remains stable even under varying wearing conditions, the earphones being worn so that an eartip of the earphone is at least partially in the external auditory canal, with at least one speaker with a frontal volume leading to a tip area and/or speaker channel, and with at least one ANC microphone. To ensure that the ANC circuit remains stable even with a small available space, the earphones feature the connection of a frontal volume and/or a speaker channel with an additional volume via a tube ending in the tip area.Type: ApplicationFiled: August 8, 2019Publication date: March 12, 2020Applicant: AUSTRIAN AUDIO GmbHInventors: Michael PERKMANN, Daniel WÖHRER
