Abstract
An electronic device includes a housing mechanism defining an accommodating chamber, a circuit board assembly accommodated in the accommodating chamber, and an anti-disassembly mechanism. The circuit board assembly includes a substrate and a controller connected to the substrate, and the substrate includes a magnetic attraction area. The anti-disassembly mechanism includes a light sensor configured to detect a light intensity in the accommodating chamber, an electromagnetic element opposite to the magnetic attraction area, and an elastic element resisting between the electromagnetic element and the substrate. When the light intensity signal is less than or equal to the light intensity threshold, the controller controls the electromagnetic element to be powered on to generate magnetic attraction to the magnetic attraction area, so that the electromagnetic element is attracted to the magnetic attraction area.
