Abstract: A device housing includes first and second cases, a first magnetically sensitive positioning pin, and a first compressible member. The first case has a first protruding block having a first positioning hole. The second case has a first groove having a second positioning hole. When the first protruding block is disposed in the first groove, the first positioning hole is aligned with the second positioning hole. The first magnetically sensitive positioning pin runs through the first and second positioning holes to position the second case on the first case.
