Abstract
A portable electronic device includes a free floating display lens having a stiffener ring mounted on a peripheral region or edge of the free floating display lens to affect modal density and modal distribution of the free floating display lens. Additionally, a piezoelectric supporting structure is attached to the stiffener ring, while surrounding a display, wherein the piezoelectric supporting structure is electrically driven to produce an acoustic signal in one mode and a vibratory haptic signal in another mode.
