Abstract
An electronic device includes an enclosure having a transparent cover defining a touch-sensitive surface, a display positioned within the enclosure and below the transparent cover, and a haptic device configured to produce a haptic output along the touch-sensitive surface. The haptic device may include a battery element electrically coupled to the display, a magnetic element, and a coil assembly fixed with respect to the enclosure and configured to induce an oscillatory movement of the battery element parallel to the display to produce the haptic output. In other examples, the coil assembly may be coupled to the battery element and the first and second magnetic elements may be fixed with respect to the enclosure.
