Abstract: Provided are an audio/video processing method and apparatus, a device, and a storage medium. The method comprises: displaying text data corresponding to an audio/video to be edited, wherein the text data has a mapping relation with an audio/video timestamp of said audio/video; displaying said audio/video according to a time axis track; in response to a preset operation triggered for target text data in the text data, determining an audio/video timestamp corresponding to the target text data as a target audio/video timestamp; and processing, on the basis of the preset operation, an audio/video clip corresponding to the target audio/video timestamp in said audio/video.

Abstract: A safety vent assembly for a cylindrical battery may include a burst disk configured to open and at least partially define a vent in response to a thermal runaway of the battery. The safety vent assembly may further include a current collector and a positive terminal. A turbulence promoter may be defined on the current collector. Gas from inside the battery may pass through the turbulence promoter and the vent formed by the burst disk during thermal runaway.

Abstract: An electronic device includes: a battery, a mainboard, and a housing. The battery is connected to the mainboard, the mainboard is provided with a first controller, the battery and the mainboard are installed in a cavity of the housing, and the housing includes a rear cover. The rear cover includes an electrochromic layer, the electrochromic layer is connected to the mainboard, the first controller is configured to control whether to power on the electrochromic layer, and a color displayed on the electrochromic layer when the electrochromic layer is powered on is different from a color displayed when the electrochromic layer is not powered on. The rear cover can change, by controlling a power-on and power-off status of the electrochromic layer, a color displayed on the electrochromic layer, and further change a color displayed on the rear cover, without changing a decorative film.
