Display-based speaker structures for electronic devices
First Claim
1. An electronic device, comprising:
- a flexible display;
a speaker structure having a speaker membrane, wherein the speaker membrane is formed from a portion of the flexible display; and
a stiffening structure configured to stiffen the portion of the flexible display that forms the speaker membrane, wherein the stiffening structure comprises a layer of foam and first and second stiffening sheets that are attached to opposing first and second sides of the layer of foam.

Abstract
Electronic devices that contain flexible displays and one or more display-based speaker structures may be provided. The speaker structures may be positioned under the flexible display. Portions of the flexible display may be used as speaker membranes for the speaker structures. The speaker structures may be driven by transducers that convert electrical audio signal input into sound. Piezoelectric transducers or transducers formed from coils and magnets may be used to drive the speaker structures. Speaker membranes may be formed from active display areas of the flexible display. Some, all, or substantially all of the flexible display may be used as a speaker membrane for one or more display-based speaker structures. An optional cover layer may be provided with speaker openings so that sound may pass from the display-based speaker structures to the exterior of the device.
