The present application provides an audio playing method, including: when an audio signal to be played is detected, storing the audio signal in a preset buffer while transmitting the audio signal to the auxiliary speaker to enable the auxiliary speaker to play the audio signal; initiating a timer to start timing in a process of storing the audio signal; and when a timing duration for which the timing lasts reaches a preset delay duration, obtaining the audio signal from the preset buffer and transmitting the audio signal to the main speaker to enable the main speaker to play the audio signal.

Example techniques relate to playback based on acoustic signals in a system including a first network device and a second network device. A first network device may detect a presence of a user using a camera and/or infrared sensors. The first network device sends, in response to detecting the presence of the user, a particular signal via the first network interface. The second network device receives data corresponding to the particular signal and plays back an audio output corresponding to the particular signal.

Example techniques involve a calibration state variable. An example implementation receives, via a network interface, an indication that the first playback device is calibrated. Based on receiving the indication that the first playback device is calibrated, the example implementation updates a calibration state variable to indicate that the first playback device is calibrated, wherein the calibration state variable is stored in the data storage. The example implementation sends, via the network interface, an indication of the updated calibration state variable to a second device.

An electronic device for configuring a hearing device parameter of a hearing device to be worn by a user, includes: a processor; a memory; and a user interface, wherein the processor is configured to: electronically obtain an initial audiogram; obtain, via the user interface, a first configuration parameter indicative of hearing loss and/or user preference in a first frequency range; determine a configuration audiogram based on the first configuration parameter and the initial audiogram; determine a gain parameter based on the configuration audiogram; and configure the hearing device parameter of the hearing device based on the gain parameter.

An acoustic control system includes a peripheral wall provided so as to surround a seat, and an upper portion of the peripheral wall being opened, a speaker provided inside the peripheral wall and capable of outputting a reproduced sound from a sound source, a microphone provided toward an outside of the peripheral wall and configured to collect an environmental sound around the peripheral wall, and a processor. The processor configured to suppresse a level of the reproduced sound in a predetermined frequency band from the speaker based on the environmental sound collected by the microphone.

An audio visualization method applied to an electronic device with a screen and a function of a silent mode is provided. The audio visualization method includes: determining whether the electronic device executes an audio/video program or not, where when the audio/video program is executed, an audio effect signal is generated; converting the audio effect signal into a two-channel signal and a multi-channel signal when the electronic device executes the audio/video program, where a channel count of the two-channel signal is less than that of the multi-channel signal; generating sound data according to the multi-channel signal when the electronic device is set to the silent mode; and generating an icon according to the sound data and presenting the icon on the screen. The disclosure also provides an audio visualization system.

A computer-implemented method comprises obtaining a physical location of a sensor on a device; determining that quality of data captured by the sensor physically located on the device is degraded based on a comparison of the captured data to a quality threshold; and, in response to determining that the quality of the data captured by the sensor is degraded, displaying a visual indicator on a display of the device. The visual indicator includes at least one non-textual component that directs a user to the physical location of the sensor on the device.

An earbud device includes a visual indicator mechanism at a body of the earbud device, a receiver at the body of the earbud device, and a speaker at the body of the earbud device. The receiver is configured to receive an audio signal from a mobile device when the earbud device is in communication with the mobile device. The speaker is configured to output audio corresponding to the received audio signal from the mobile device. The visual indicator mechanism is configured to output at least one visual indication when the earbud device is in use. The visual indication output by the visual indicator mechanism can be a first visual indication output from the visual indicator mechanism corresponding to a first preset earbud use type and/or a second, different visual indication output from the visual indicator mechanism corresponding to a second, different preset earbud use type.
