This application relates to a keyboard protector and an electronic device. The electronic device includes a cavity antenna, a frame, and a screen. The frame includes a radiating segment facing the opening of the cavity antenna, and a radiating gap is formed between the radiating segment and the screen. The keyboard protector includes a housing and a metal keyboard. The inner side of the housing is used to connect the electronic device. The metal keyboard includes a keyboard surface and a placement surface disposed opposite each other. The metal keyboard includes an antenna window extending from the placement surface to the keyboard surface. When the keyboard protector and the electronic device are assembled and the keyboard protector is in a closed state, at least a portion of the projected area of ​​the radiating gap is located within the antenna window. The design of the keyboard protector in this application allows the antenna signal to radiate outward through the antenna window, effectively avoiding interference from the metal keyboard to the cavity antenna signal, ensuring the radiation efficiency of the antenna signal, improving the user experience, and enhancing the electromagnetic compatibility of the device.

This application discloses an electronic device, including an antenna radiator, a display module, and a current blocking component. The display module includes a frame and a flexible display panel, with a portion of the flexible display panel located on one side of the frame. The flexible display panel is provided with a first connecting piece, which is electrically connected to the frame. The current blocking component is electrically connected to a reference ground of the flexible display panel and the first connecting piece, respectively, and is used to block the coupling current at the connection point between the first connecting piece and the frame. The electronic device of this application, by adding a current blocking component, impedes and suppresses the coupling current formed at the connection point between the first connecting piece and the frame, thereby making it less prone to harmonic generation at the connection point, avoiding spurious radiation problems, ensuring the stability of the fundamental signal of the electronic device, and without affecting the radiation efficiency of the antenna and the system efficiency.
