1. A portable electronic device, comprising:
- a. a free floating display lens having a stiffener ring mounted on a peripheral region or edge of the free floating display lens;
b. one or more electromechanical transducers carried on a supporting structure, the supporting structure having a first end attached to the stiffener ring;
c. a display positioned between the free floating display lens and the supporting structure;
d. a user interface controller that sends signals to the one or more electromechanical transducers to enable an acoustic signal in one mode and a vibratory haptic signal in another mode; and
e. a housing that substantially encloses the one or more electromechanical transducers, the display, and the user interface controller.

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.

18. A method for providing audio and haptic signals to a display lens of a portable electronic device, comprising the steps of:
-
a) driving an electromechanical transducer carried by a supporting structure with an electrical signal to enable an acoustic signal in one mode and a vibratory haptic signal in another mode; and b) controlling frequency along varying thickness portions of a stiffener ring carried on the supporting structure.
