In non-limiting examples of the present disclosure, systems, methods and devices for initiating and managing electronic focus sessions are provided. A focus session window may be displayed. The focus session window may comprise a timer pane comprising a focus session duration input element; a task pane comprising an identity of at least one task object created by a task management application; a music pane comprising an identity of at least one music playlist; and/or a daily progress pane that includes a goal display element indicating a duration of time spent in focus sessions for a current day. An indication to initiate a focus session may be received. The initiating may comprise causing a timer for the duration of time to be initiated and displayed in the timer pane and causing one of the music playlists to be automatically played.

Embodiments of this application provide a volume adjustment method and device, and a system. The method includes: A first terminal device sends a first playback request to a server, where the first playback request carries a model of the first terminal device and an identifier of the first audio. The server determines a first volume value of the first audio based on the identifier of the first audio and the model of the first terminal device. The server determines, based on the first volume value and a preset volume threshold of the first terminal device, a first volume gain. The first terminal device determines, based on the first volume gain and a currently set second volume value, a first target volume value. The first terminal device adjusts volume of playing the first audio to the first target volume value.

A BLUETOOTH communications system includes a true wireless stereo (TWS) BLUETOOTH headset and a terminal device, where the TWS Bluetooth headset includes a first earbud and a second earbud. The terminal device controls the first earbud to collect a sound signal and the second earbud to play a sound signal. When an audio application on the terminal device is started, the first earbud collects a first sound signal, performs sound effect processing on the first sound signal to obtain a second sound signal, and sends the second sound signal to the second earbud. The terminal device sends accompaniment audio to the second earbud, and the second earbud performs audio mixing processing on the accompaniment audio and the second sound signal for playing.

A signal processing method includes: receiving, by a first reception unit, an acoustic signal transmitted via a first transmission path, the acoustic signal received by the first reception unit being a first acoustic signal; receiving, by a second reception unit, the acoustic signal transmitted via a second transmission path different from the first transmission path, the second transmission path having a longer delay time for transmission than the first transmission path, and the acoustic signal received by the second reception unit being a second acoustic signal; calculating, by a delay amount calculation unit, a transmission delay amount that is a relative delay amount between the first acoustic signal and the second acoustic signal; and delaying, by a delay amount addition unit, the first acoustic signal based on the calculated transmission delay amount and outputting the delayed first acoustic signal.

A Bluetooth communication method is disclosed, and relates to the field of short-range wireless communications technologies. The method includes: A terminal receives a play operation performed by a user on first audio data. The terminal sends first indication information to a Bluetooth device when a service type of the first audio data is a first service type, where the first indication information is used by the Bluetooth device to set a buffer time length for the audio data to first duration. The Bluetooth device receives the first audio data sent by the terminal via Bluetooth, and buffers the first audio data. The Bluetooth device starts to play the buffered first audio data when the buffer time length for the first audio data reaches the first duration. In this way, the terminal can perform targeted delay control on audio data playback of the Bluetooth device in different application scenarios.

An electronic device includes a display, a processor and a memory storing instructions executable by the processor where the processor is connected to the memory and configured to collect a usage log of the electronic device, identify a usage pattern according to a user characteristic by analyzing the usage log, generate a personalized user context corresponding to an undefined situation that is not predefined in the electronic device based on the usage pattern, and output a recommendation service to the display in response to recognizing the personalized user context.

In various examples, audio received from a source device is shared from a first wireless earbud to one or more other wireless earbuds. For example, source-device settings are shared by the first wireless earbud with the one or more other wireless earbuds to facilitate synchronization and passive receipt of data transmitted by the source device. Once the wireless earbuds are synchronized, they may check in with one another in a coordinated manner to share packets that were missed when passively listening to the source device.

A portable multifunction device displays a first user interface object and a second user interface object on a touch screen display. Upon detecting a finger-down event at the first user interface object and one or more finger-dragging events on the touch screen display, the device moves the first user interface object on the touch screen display along a path determined by the finger-dragging events until the first user interface object at least in part overlaps the second user interface object. Upon detecting a finger-up event at the second user interface object, the device visually replaces the second user interface object with the first user interface object.

Message notifications to an accessory from a mobile communication device are provided according to some embodiments of the invention. When a message such as a text message, email, and/or voicemail is received at a mobile communication device, the mobile communication device can notify an attached accessory that a message has been received. In response, the accessory can request the full message, media associated with the message, an attachment to the message, and/or an audio/video stream of the message for presentation to a user.
