Systems and methods for output of audio content are disclosed. An example first playback device includes a processor. The example processor is configured to at least process audio content to determine a portion of the audio content to be output by the first playback device based on a type of pairing of the first playback device and the audio content. The example processor is configured to at least determine, when the type of pairing pairs the first playback device with a second playback device to output the audio content, a time delay to facilitate sound synchronization with the second playback device. The example processor is configured to at least configure, based on the type of pairing and the time delay, the first playback device to output the portion of the audio content via an amplifier and a plurality of speaker drivers.

Various implementations include audio systems and methods for mixed rendering to enhance audio output. Certain implementations include an audio system having: at least one far-field speaker configured to output a first portion of an audio signal; and a pair of non-occluding near-field speakers configured to output a second portion of the audio signal in synchrony with the output of the first portion of the audio signal, where the first portion of the audio signal is distinct from the second portion of the audio signal.

Systems and methods for vocal guidance for playback devices are disclosed. A playback device can include a first wireless transceiver for communication via a first data network and a second wireless transceiver for communication via a second data network. The device includes one or more processors and is configured to maintain a library that includes one or more source device names and corresponding audio content, the audio content configured to be played back via an amplifier to indicate association of a particular source device with the playback device via the first data network. The device receives, via the second data network, information from one or more remote computing devices, and based on the information, updates the library by: (i) adding at least one new source device name and corresponding audio content; (ii) changing at least one source device name or its corresponding audio content; or both (i) and (ii).

A display device has a processor and a memory connected to the processor. The memory stores instructions executed by the processor to make a first determination that an internal display device speaker is disabled. A second determination that an external sound system is unavailable is established. A prompt is provided in response to the first determination and the second determination. The prompt includes an option to enable the internal display device speaker.

An audio output method applied to an electronic device having a proximity sensor, where the method includes obtaining proximity data of the proximity sensor when the electronic device is coupled to an audio output device and has an audio signal to output, outputting, by an earpiece of the electronic device, the audio signal when the proximity data meets a preset condition, determining a type of the audio output device, and selecting, based on the type of the audio output device, whether to output the audio signal using the audio output device. Hence, an earpiece is enabled to output an audio signal under a specific condition when an electronic device including a mobile phone is coupled to another audio output device, thereby improving user experience.

Provided are a terminal, a terminal peripheral, a signal transmission system, and a signal sending and receiving method. The terminal includes: a first audio module, which is connected to the USB receptacle in a terminal through an I2S bus channel and is configured to send a signal to be sent to a USB receptacle; the USB receptacle is configured to provide a physical connection interface between the terminal and a terminal peripheral.

A method for controlling earphone switching, an earphone, and an earphone system are provided. The method includes the following. A first earphone determines whether the first earphone is switched to a non-wearing state from a wearing state. The first earphone is coupled with a second earphone and an electronic device and serves as a master earphone, and the second earphone serves as a slave earphone. When the first earphone is determined to be switched to the non-wearing state from the wearing state, the first earphone switches the first earphone to serve as the slave earphone and the first earphone switches the second earphone to serve as the master earphone. Switching between master and slave earphones can be achieved according to changes between the wearing state and the non-wearing state of the master earphone, such that user experience can be improved.

The present disclosure provides an audio playback system adapted to automatically switch an active microphone back and forth between two or more devices. For example, where the system is a pair of earbuds, where each earbud is worn by a separate user, the system may switch the active microphone to the device worn by the user that is speaking at a given time. While that device holds the active microphone, the other device may wait until a particular event that frees up the microphone, such as if the user wearing the device with the active microphone stops talking. According to some examples, a notification may be provided through one or more of the devices in the system to let the user know, for example, that he does not have the active microphone, that the active microphone is free, that the active microphone has been switched, etc.

An audio processing apparatus comprises a receiver (705) which receives audio data including audio components and render configuration data including audio transducer position data for a set of audio transducers (703). A renderer (707) generating audio transducer signals for the set of audio transducers from the audio data. The renderer (7010) is capable of rendering audio components in accordance with a plurality of rendering modes. A render controller (709) selects the rendering modes for the renderer (707) from the plurality of rendering modes based on the audio transducer position data. The renderer (707) can employ different rendering modes for different subsets of the set of audio transducers the render controller (709) can independently select rendering modes for each of the different subsets of the set of audio transducers (703). The render controller (709) can select the rendering mode for a first audio transducer of the set of audio transducers (703) in response to a position of the first audio transducer relative to a predetermined position for the audio transducer. The approach may provide improved adaptation, e.g. to scenarios where most speakers are at desired positions whereas a subset deviate from the desired position(s).
