Abstract: Disclosed are a battery and an electronic device, including a housing, a sealing cover, and a battery cell. The housing has an accommodation cavity, and the battery cell is located in the accommodation cavity. The housing is provided with a liquid injection hole. An upper surface of a peripheral edge of the sealing cover is provided with a first step, and the first step divides the sealing cover into a first cover area and a second cover area. The thickness of the second cover area is less than or equal to a thickness of the housing at a seal-welding position with the second cover area. The battery provided in embodiments of the present disclosure has good seal-welding performance, to resolve problems of low battery yields, difficulty in mass production, and failure to achieve expected safety and stability due to poor seal-welding performance.

Abstract: A control method includes detecting a first object within a first range corresponding to an output device, obtaining a first relative position relationship between the first object and the output device, and adjusting an output parameter of output light of the output device based on the first relative position relationship, to cause the output device to be in a first output state relative to the first object.

Abstract: A heat conducting device, comprising a first heat conducting board and a heat conducting structure, the first heat conducting board comprising an upper heat conducting arm provided on one surface of the first heat conducting board, the heat conducting structure slidably abutting against the upper heat conducting arm of the first heat conducting board to form a contact surface through which heat transfer is realized, the heat conducting structure comprising a heat conducting surface, wherein the heat conducting structure is used to keep the relative position between the first heat conducting board and the heat conducting surface, allow the varying of the distance between the first heat conducting board and the heat conducting surface of the heat conducting structure through relative sliding between the upper heat conducting arm and the heat conducting structure.
