A protective case (b2) and device having same, comprising an electronic device (b4) and a protective case (b2); the electronic device (b4) comprises a display screen (P) and a Hall sensor (H); the protective case (b2) is provided with magnets thereon comprising at least two magnets (b22, b24); the magnetic line of at least one magnet (b22, b24) passes through the Hall sensor (H) when the protective case (b2) covers the display screen (P); With at least two magnets (b22, b24) being provided in the protective case (b2), the magnetic line of at least one of the two magnets (b22, b24) passes through the Hall sensor (H) in the electronic device (b4) when the protective case (b2) covers and moves over the display screen (P), thus solving the problem in the relevant art that the increased strength of the magnets (b22, b24) affects the stability of an electronic floppy disk. Without increasing the strength of the magnets (b22, b24), if the protective case (b2) moves, the magnetic line of one of the magnets (b22, b24) can still pass through the Hall sensor (H), thus effectively ensuring accuracy of screen locking and screen wakeup. |
