The present disclosure provides systems and method for adjusting the audio output of a wearable device based on an audio gain profile of a user. The wearable device may receive an audiogram indicating one or more frequency ranges associated with hearing loss. The wearable device may determine the audio gain profile based on the audiogram. The wearable device may use one or more adjustment modules to determine a gain to apply to the audio output based on the audio gain profile. The adjustment modules may include an active noise control module, a hearing assistance module, and a transparency control module. The wearable device may determine the amount of gain to apply using a least mean square algorithm and/or a machine learning model.

Adaptive active noise control system with hearing assistance mechanism

The present disclosure provides systems and method for determining a background noise level. The device may receive audio from two or more microphones. The audio may include a first signal and a second signal, such that each microphone receives its own signal. The time, loudness, frequency of the first and second signals may be compared to determine the source of the audio, such as whether the audio is the user's voice or background noise. Based on the source of the audio, the audio may be suppressed to reduce false estimations when calculating the background noise level.

Methods, systems, and devices for enhanced digital headsets are disclosed. An enhanced USB-C headset includes a USB-C connector, a cable extending from the USB-C connector, an inline control box coupled to the USB-C connector through the cable, and a first earphone and a second earphone. The cable includes conductors for transmitting DC bus power, power return, and differential digital signals and extends at least one foot in length. The control box includes a single circuit board, with circuitry for managing digital communications, converting audio data, and providing output signals to drive analog speaker elements of the earphones.

A computing device may include a multi-functional port in a base housing of the device. The multi-functional port may include an audio input device that can receive and process external audio input signals through an opening in the base housing. The multi-functional port may include a light source that can output light through the opening in the base housing. The multi-functional port may include a microphone boot. The microphone boot may guide external audio input signals into to the audio input device for processing. The microphone boot may also guide light, emitted by the light source, out of the base housing.

Combined microphone and lighting device and computing device having same

Exemplary wearable computing systems may include a head-mounted display that is configured to provide indirect bone-conduction audio. For example, an exemplary head-mounted display may include at least one vibration transducer that is configured to vibrate at least a portion of the head-mounted display based on the audio signal. The vibration transducer is configured such that when the head-mounted display is worn, the vibration transducer vibrates the head-mounted display without directly vibrating a wearer. However, the head-mounted display structure vibrationally couples to a bone structure of the wearer, such that vibrations from the vibration transducer may be indirectly transferred to the wearer's bone structure.

Systems and methods for switching a computing device from a low-power state to a high-power state are provided. In some aspects, a method, implemented on a power management processing unit of the computing device, includes receiving, while the computing device is in the low-power state, a first audio signal. The method also includes verifying the first audio signal based on an audio signal key. The method also includes providing, in response to verifying the first audio signal, instructions for switching the computing device from the low-power state to the high-power state.

A system for porting a speaker through a keyboard module and a backlight module is provided. The system includes an enclosure, the enclosure configured to mount the keyboard module, the backlight module, and the speaker thereto, wherein the speaker is disposed under a portion of the keyboard module and the backlight module. The system also includes a port path for porting the speaker through the keyboard module and the backlight module, the port path extending from the speaker to an outer surface of the keyboard module, wherein a first portion of the port path includes a passage in the enclosure, the passage disposed adjacent to an edge of the keyboard module and the backlight module, and wherein a second portion of the port path includes a periphery of a key of the keyboard module.

An electronic device may include an audio jack allowing a peripheral audio output device to be connected to the electronic device by inserting the plug into the jack. The jack may include a receptacle that extends into the housing. A plurality of contacts may be included in the receptacle, arranged along a longitudinal direction of the receptacle. A latch may be installed in the receptacle, at an intermediate location between the proximal end and the distal end of the receptacle, to secure a position of the plug in the receptacle. A detect contact may be positioned at the distal end of the receptacle, separate from the latch. The detect contact may be actuated by the distal end of the tip of the plug to indicate that the plug is fully inserted in the receptacle. Upon actuation of the detect contact, the device may transfer audio output functionality to the peripheral device connected to the device by the plug inserted in the jack.

An integrated port for connecting a device with an accessory having a plug is provided. An opening in the device may provide access to a recess of the port for receiving one or more connectors of the plug. The recess may include one or more terminals for electrically coupling with one or more connectors of the plug in a first mode of operation. The recess may also include a switch, which may be activated to change the operational state of the device from the first mode of operation into a second mode of operation that is not intended for general use. The switch may be provided such that insertion of the plug into the recess via the opening electrically couples the one or more terminals of the port with the one or more connectors of the plug without activating the switch.
