Patent attributes
Embodiments are disclosed for a haptic engine module that includes AROD magnets. The AROD magnets comprise two adjacent magnets with opposite polarization and adjacent coils above and/or below the magnets. The magnets and coils are adjacent in along direction, which is the direction that is perpendicular to the vibration direction (the direction of the Lorentz force) and to the polarization direction (the direction of magnetic flux). When in operation, excitation current flows in the two coils in opposite directions. The haptic engine module can be embedded in an electronic device with an extreme aspect ratio (e.g., a touch bar of a notebook computer) to provide haptic force (e.g., vibration, click) that can be felt by a user holding or touching the electronic device.
