Abstract: A control method applied to an electronic device includes, in response to detecting that a first interface of the electronic device is accessed to an external device, determining whether the external device is a signal source device of a multi-media signal source, in response to the external device being the signal source device of the multi-media signal source, controlling a multi-media output controller of the electronic device to power on, and controlling the electronic device to switch to a first mode, in the first mode, the electronic device being controlled to be a multi-media output terminal of the external device. In the first mode, the multi-media output controller receives first multi-media data of the external device. First display data of the first multi-media data is converted into a second display signal based on a size of a target display area of a display of the electronic device.

Abstract: A control method includes: determining whether first parameters reported by a plurality of speakers satisfy a target condition, the plurality of speakers being disposed at different positions in an electronic device, and each first parameter describing a power supply signal of each speaker; and controlling the plurality of speakers to change their first gain to a same second gain.

Abstract: An electronic device includes a body having a receiving housing and an opening, a function module disposed in the receiving housing, a transmission module configured to transmit a signal between a first end of the transmission module and a second end of the transmission module, and a heat dissipation module disposed along the transmission module. The first end of the transmission module is located in the receiving housing, and the second end of the transmission module is located outside the receiving housing. The heat dissipation module is configured to transfer heat generated by the function module to the second end of the transmission module.

Abstract: An information processing method and an electronic device are provided. The information processing method is applied to the electronic device, the electronic device includes a touch display unit including a display region and an operation region, and the method includes: detecting a first input operation, the first input operation being an input operation performed in the operation region; identifying the first input operation; and executing a predetermined instruction to move first display content in the display region to a first display region corresponding to the predetermined instruction to generate second display content, if it is determined that the first input operation includes the predetermined instruction, where the first display region is smaller than the display region.
