Abstract: An electronic device can include an actuator unit with a button, where the actuator unit requires application of at least a threshold actuation force to an accessible surface of the button. The electronic device may also include a tactile compensation unit that is in physical communication with the actuator unit. The tactile compensation unit is rendered operable when a triggering magnetic element forms a magnetic circuit with the triggering unit, such that the tactile compensation unit operates to maintain the activation of the actuator unit using no more than the threshold actuation force.

Abstract: A case for a portable electronic device, the portable electronic device having a housing that carries a first magnetic element capable of forming a first magnetic circuit through the housing with a magnetic element external to the portable electronic device capable of securing together the housing and the external magnetic element. The case can include a body having a bottom wall and side walls that combine to define a recessed region suitable for retaining the portable electronic device and a second magnetic element located at a position corresponding to the external magnetic element such that when the portable electronic device is carried in the recessed region, the second magnetic element forms a second magnetic circuit through the body with the external magnetic element that is capable of securing together the case and the external magnetic element.
