摘要： This application provides a TWS earphone, and a play method and apparatus of a TWS earphone. The TWS earphone includes an audio signal processing path, a frequency divider, and at least two speakers. An output end of the audio signal processing path is connected to an input end of the frequency divider, and an output end of the frequency divider is connected to the at least two speakers. The audio signal processing path is configured to output a speaker drive signal. The frequency divider is configured to divide the speaker drive signal into sub-audio signals of at least two frequency bands. The at least two frequency bands correspond to main operating frequency bands of the at least two speakers. Adjacent frequency bands in the at least two frequency bands partially overlap, or adjacent frequency bands in the at least two frequency bands do not overlap. The at least two speakers are configured to play the corresponding sub-audio signals. This application can provide a high-quality audio source in various frequency bands, and can also support ultra-wideband audio calls.

摘要： This application provides a system and method for displaying and controlling a task of a remote device. The system includes N devices, and the N devices include a first terminal and a second terminal. Icons of the N devices and at least one task card are displayed on a recent tasks screen of the first terminal. A user may perform various convenient operations on any card, to implement migration of the task card and running of an application corresponding to the task card on different devices. This can be suitable for a variety of different user requirements, and applicable to almost all applications. In addition, task cards can be flexibly arranged on the first terminal, and the first terminal can display task cards of different devices. There is no need to perform adaption by an application, and a requirement of the user for managing and controlling tasks of a plurality of devices is met. In addition, a user operation procedure during task migration is simplified, user operations are simplified, and user experience is improved.

摘要： This application provides a task migration system and method. The system includes a first terminal and a second terminal. The second terminal runs a first application. The first terminal opens a recent task interface after receiving an operation performed by a user, where the recent task interface includes an identifier of the second terminal; after receiving an operation performed by the user on the identifier of the second terminal, displays, in the recent task interface, at least one task card corresponding to an application run by the second terminal in the background; and after receiving an operation performed by the user on a first task card corresponding to the first application, runs the first application, and displays a first user interface of the first application. After displaying the first user interface and receiving an operation performed by the user in the first user interface, the first terminal displays a parent interface or a sub-interface of the first user interface, instead of displaying a home screen of the first terminal device. This conforms to a use habit of the user, is friendly to the user, helps the user perform a subsequent operation, and improves user experience.
