Abstract: 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.

Abstract: A method for routing audio content through an electronic device that is to be worn by a user. The method obtains a communication and determines whether the communication is private. In response to determining that the communication is private, the method drives a bone conduction transducer of the electronic device with an audio signal associated with the communication. In response to determining that the communication is not private, however, the method drives a speaker of the electronic device with the audio signal.

Abstract: An audio component for a head-mounted display system includes a first port through which sound is projected to a user during operation in a first audio mode, a second port through which sound is projected to a user during operation in a second audio mode, an insulator positioned along an acoustic path between the first port and the second port, wherein the insulator is configured to inhibit sound projection along the acoustic path by isolating the first port from the second port, and an earpiece configured to engage the audio component to an ear of the a user, to deliver sound from the audio component to the user, and to reduce ambient noise from a surrounding environment during operation of the audio component in the second audio mode.

Abstract: A head-mounted display system is disclosed that includes a housing; a visual system associated with the housing to facilitate image and/or video display; a wearable support connectable to the housing; and an audio component pivotably connected to the support such that the audio component is movable between a first position in which the audio component is in general alignment with the support, and a second position in which the audio component is out of general alignment with the support. Movement from the first position to the second position transitions the audio component from a first mode (i.e., an extra-aural mode) in which sound is projected through a first port in communication with a driver to a user to a second mode (i.e., an intra-aural mode) in which sound is projected through a second port in communication with the driver to the user.

Abstract: An optical module for a display system includes a lens, a display screen, a movement mechanism, and one or more pressure-relieving features. The display screen cooperatively defines a chamber with the lens. The lens and the display screen are moved relative to each other by the movement mechanism. The one or more pressure-relieving features are in fluid communication with the chamber to hinder pressure in the chamber as the lens and the display are moved relative to each other.

Abstract: A method performed by a processor of a computer system including a headset that is to be worn on a head of a user. The method drives a speaker of the headset with an input audio signal to output sound into an environment. The method determines that the speaker is at least partially covered with a cupped hand. In response to determining that the speaker is at least partially covered with the cupped hand, applying a gain to the input audio signal to reduce an output sound level of the speaker.

Abstract: Various implementations disclosed herein include devices, systems, and methods for providing situational awareness for HMD users. Some implementations involve providing a CGR experience to a first user wearing an HMD in a physical environment. Audio data or image data is obtained from a sensor at the physical environment during the CGR experience and an emotional state or direction of attention of a second person other than the first user is detected based on the audio data or image data. A notification or other change is provided in the CGR experience based on detecting the emotional state or direction of attention of the second person.

Abstract: A system including an audio source device having a first microphone and a first speaker for directing sound into an environment in which the audio source device is located and a wireless audio receiver device having a second microphone and a second speaker for directing sound into a user's ear. The audio source device is configured to 1) capture, using the firs microphone, speech of the user as a first audio signal, 2) reduce noise in the first audio signal to produce a speech signal, and 3) drive the first speaker with the speech signal. The wireless audio receiver device is configured to 1) capture, using the second microphone, a reproduction of the speech produced by the first speaker as a second audio signal and 2) drive the second speaker with the second audio signal to output the reproduction of the speech.

Abstract: A display system includes a head-mounted display unit and a detachable speaker unit. The head-mounted display unit outputs visual content to a user and provides a visual pass-through of a real environment to the user. The detachable speaker unit is detachably coupleable to the head-mounted display unit for providing aural content to the user. At least one of the visual content or the aural content is changed according to a position of the detachable speaker unit relative to the head-mounted display unit.
