Abstract: An electronic device may include one or more terminals configured to provide a voltage signal to an actuator. The electronic device may detect a current associated with the voltage signal provided by the terminal to the actuator. The electronic device may determine an impedance across associated with the actuator based on the voltage signal and the electrical current. The electronic device may compare the impedance to a threshold impedance to determine whether there is sufficient skin contact with the actuator. The electronic device may provide audio via cartilage conduction if there is sufficient contact based on comparing the impedance to the threshold impedance, or may output a notification to the user to adjust placement of the electronic device to improve contact.

Abstract: An audio system is described for calibrating one or more transducers for a user using the auditory steady state response (ASSR) of the user. The audio system presents an audio calibration signal to the user via a transducer array in the headset. The system measures electrical signals that are generated in the auditory cortex of the brain of the user in response to the presented audio calibration signal. The audio system determines an ASSR of the user based on the measured electrical signals. The audio system determines a value for one or more sound filter parameter based on the determined ASSR and a model. The audio system calibrates the transducer array using the determined sound filter parameters. The calibrated transducer array is used to present audio content to the user.

Abstract: A real-time in-ear EEG signal verification system. The system includes an in-ear device (IED) configured to be placed within an ear canal of a user and a controller. The IED includes a speaker configured to present a calibration audio signal to the user, the calibration audio signal being embedded with a predetermined audible feature, and an in-ear electrode configured to be in contact with an inner surface of the ear canal. The controller is configured to instruct the speaker to present the calibration audio signal to the user, and generate neural signal data based on electrical signals from the in-ear electrode. The electrical signals correspond to brain activity of the user in response to the predetermined audible feature. The controller is configured to determine a quality of the generated neural signal data, and perform an action based on the quality of the neural signal data.

Abstract: A design system generates a design for an in-ear device customized for a user. The in-ear device produces audio content for the user. The design system captures anthropometric data of the user. Using machine learning techniques, the design system determines features of an ear of the user from the anthropometric and generates a three dimensional (3D) geometry of the user's ear. A design for the in-ear device is generated based on the 3D geometry of the user's ear and includes a shell configured to fit in at least a portion of an ear canal of the user.

Abstract: An in-ear device occludes an ear canal of an ear of a user. The in-ear device is configured to be calibrated such that the user perceives audio content as though the in-ear device is not occluding the ear canal. A transducer of the in-ear device presents audio content, and an inner microphone of the in-ear device detects sound pressure data within the ear canal. A controller of the in-ear device determines a blocked sound pressure at the entrance to the ear canal based on sound pressure data from an outer microphone. The controller generates sound filters custom to the user based in part on the detected sound pressure within the ear canal and the blocked sound pressure at the entrance to the ear canal. The controller adjusts audio content using the sound filter, and the transducer presents the adjusted audio content to the user.

Abstract: An ear-plug device is an in-ear device that presents audio content to an ear canal of a user. The in-ear device includes a body configured to at least partially fit inside the ear canal of the user, and a transducer assembly coupled to the body. The transducer assembly comprises at least one transducer located within the ear canal. The at least one transducer is configured to vibrate a portion of the ear canal to cause the ear canal to create an airborne acoustic pressure wave in the ear canal in accordance with vibration instructions. The airborne acoustic pressure wave corresponds to and is for presentation of the audio content to the user.

Abstract: An open-ear device performs active noise cancellation (ANC) for a user. A sensor located outside an ear of a user which does not occlude an ear canal of the ear and measures vibrational data indicative of a sound pressure level at a location outside the ear, or a level of pinna vibration of the user. A prediction pipeline generates a prediction of sound pressure within the ear canal using an individualized model, taking into account the measured vibrational data and the unique geometric shape of the user's head and pinna. This sound pressure prediction is used to generate audio instructions for rendering playback at an noise cancellation source, such as a bone conduction transducer and/or cartilage transducer, to perform ANC for the user by cancelling at least portion of the sound received at the ear canal.

Abstract: An electronic system is described that is responsive to non-verbal commands. The system may include a display component for presenting visual content to a user and an audio system, such as an in-ear or over-the-ear speaker system. The speaker system may be equipped with a bone conduction sensor or in-ear microphone that generates data associated with vibrations of a facial region of the user. The system may use the data to detect non-verbal command in the form of grunts, hums, coughs, tongue clicks, and the like. The system may perform various predetermined operations based on the detected vibrations.

Abstract: An artificial-reality device for audio playback is provided. The artificial-reality device includes: (i) a head-mounted display including at least one lens, and (ii) one or more transducers, coupled to the head-mounted display. The transducers are configured to generate signals that vibrate the at least one lens of the head-mounted display. The at least one lens generates acoustic waves that correspond to media presented by the head-mounted display when vibrated by the one or more transducers. Characteristics of the signals generated by the one or more transducers cause the acoustic waves generated by the at least one lens to be directed towards at least one ear of a user of the artificial reality device. Values of the characteristics for the signals are determined based on: (i) the media presented by the head-mounted display and (ii) characteristics of the at least one lens.
