Publication number: 20240107246Abstract: Aspects of the subject technology provide improved techniques for determining a state of an audio device, including reduced power techniques for determining if an earbud is currently being worn in a user's ear or not. In aspects, a potential state change in an audio device may be detected, and in response measurement of the state of the device may be initiated, such as by emitting an audio signal and then determining the state of the audio device based on a sensed version of the emitted audio signal.Type: ApplicationFiled: August 29, 2023Publication date: March 28, 2024Inventors: Tom-Davy W.

Publication number: 20240073638Abstract: A method for self-calibrating a sound pickup process that uses a microphone array in a wearable device that also includes a loudspeaker, where the microphone array being in a physical arrangement with respect to the loudspeaker. The method obtains, for each of several microphones of the microphone array, one or more transfer functions that each represent a response of the microphone to sound from a position in an acoustic space. The method determines whether a physical arrangement of the microphone array with respect to the loudspeaker has changed and adjusts the transfer function, for at least one of the microphones of the several microphones, in response to determining that the current physical arrangement of the microphone array with respect to the loudspeaker has changed.Type: ApplicationFiled: October 30, 2023Publication date: February 29, 2024Inventors: Jonathan D. Sheaffer, Daniel K. Boothe, Martin E. Johnson, Neal D. Evans, Nikolas T. Vitt, Christopher T. Eubank, Peter V. Jupin, Symeon Delikaris Manias, Shai Messingher Lang

Publication number: 20240048895Abstract: Loudspeakers are described that may reduce comb filtering effects perceived by a listener by either 1) moving transducers closer to a sound reflective surface (e.g., a baseplate, a tabletop or a floor) through vertical (height) or rotational adjustments of the transducers or 2) guiding sound produced by the transducers to be released into the listening area proximate to the reflective surface through the use of horns and openings that are at a prescribed distance from the reflective surface. The reduction of this distance between the reflective surface and the point at which sound emitted by the transducers is released into the listening area may lead to shorter reflected path that reduces comb filtering effects caused by reflected sounds that are delayed relative to the direct sound. Accordingly, the loudspeakers shown and described may be placed on reflective surfaces without severe audio coloration caused by reflected sounds.Type: ApplicationFiled: October 5, 2023Publication date: February 8, 2024Applicant: APPLE INC.Inventors: Martin E. Johnson, Simon K. Porter, Suzanne Hardy, John H. Sheerin

Patent number: 11812247Abstract: In a device or method for rendering a sound program for headphones, a location is received for placing the sound program with respect to first and second ear pieces. If the location is between the first ear piece and the second ear piece, the sound program is filtered to produce low-frequency and high-frequency portions. The high-frequency portion is panned according to the location to produce first and second high-frequency signals. The low-frequency portion and the first high-frequency signal are combined to produce a first headphone driver signal to drive the first ear piece. A second headphone driver signal is similarly produced. The sound program may be a stereo sound program. The device or method may also provide for a location that is between the first ear piece and a near-field boundary. Other aspects are also described.Type: GrantFiled: March 15, 2022Date of Patent: November 7, 2023Assignee: Apple Inc.Inventors: Martin E. Johnson, Afrooz Family, Darius A. Satongar, Jonathan D.

Patent number: 11726161Abstract: Disclosed are techniques for a multimedia device with audio and video capturing capability to identify an audio device based on acoustic playback signal if the audio device cannot be identified from captured video. The multimedia device may assemble a list of candidate audio devices that are a possible match for the observed audio device from a database of previously recognized audio devices and may transmit commands to the candidate audio devices to play acoustic identification signals. The acoustic identification signals may be audible sound or ultrasonic tone sequences with embedded identification information unique to each audio device. The multimedia device may record and analyze the acoustic identification signals received from any of the candidate audio devices to construct metrics to select the most likely candidate for the observed audio device. The metrics may include time of flight, direction of arrival, received amplitude, direct-to-reverberant ratio (DRR) of the acoustic identification signals.Type: GrantFiled: September 1, 2021Date of Patent: August 15, 2023Assignee: Apple Inc.Inventors: Christopher T.

Publication number: 20230217204Abstract: Implementations of the subject technology provide user tracking headrest audio control. For example, a seat may have a headrest and one or more speakers mounted to the headrest for providing audio output to an occupant of the seat. Because the head of the occupant may be disposed in the near field of the headrest speakers when the occupant is seated in the seat, movements of the occupant's head and/or ears may affect the acoustic experience of the occupant. Aspects of the subject technology provide for modifications to audio output(s) from one or more speaker(s) mounted in a headrest, based on tracking of the location of the occupant's head and/or ears relative to the location(s) of the speaker(s).Type: ApplicationFiled: December 15, 2022Publication date: July 6, 2023Inventors: Daniel K.
