Abstract:
Various embodiments for magnetic detent assemblies provide for detent devices with improved performance and manufacturability. In one embodiment, magnetic detent assemblies provide for custom detent positions and custom force profiles by including a pair of unitary magnetic components each having a special geometry. In an embodiment, the changing area of overlap (and hence magnetic flux) between the magnetic components can give rise to the custom detent positions and custom force profiles. In a specific embodiment, the magnetic components can comprise an N-point star shaped geometry, where the number and distribution of the start wings can be varied to define customized detent positions and the contour of the star wings can be varied to create customized force profiles. In other embodiments, devices such as laptop computers and docking stations for handheld electronic devices can implement multi-position detent hinges with the magnetic detent assemblies.
