Abstract:
1. A magnetic latch mechanism for latching a first electronic assembly to a second electronic assembly, the magnetic mechanism comprising: a Halbach array captured by the first electronic assembly, the Halbach array configured to provide a first magnetic flux in a first direction; an attraction plate captured by the second electronic assembly and configured to be coupled with the first magnetic flux when the first electronic assembly is in a closed position with respect to the second electronic assembly such that there is mutual attraction between the attraction plate and the Halbach array in the closed position; a tuning bumper, the tuning bumper disposed between the first and second electronic assemblies when the first electronic assembly is in the closed position with respect to the second assembly and configured to tune an intensity of a magnetic attraction force between the attraction plate and the Halbach array; and a second tuning bumper, wherein the tuning bumper is replaceable by the second tuning bumper, the tuning bumper having a first predefined height, the second tuning bumper having a second predefined height, the first predefined height being different from the second predefined height.
