Abstract
A transparent ultrasonic audio speaker includes an emitter and a driver. The emitter can include first and second transparent conductive sheets. The conductive sheets can comprise a base layer and a conductive layer, and can be transparent. The transparent ultrasonic audio speaker can be configured to be positioned on or in place of the display screen of a content device.
