NOVELTY - The speaker has a transparent conductor (46a) arranged on a first transparent base layer (45b). A partially open transparent conductive layer is arranged on a second transparent base layer (46b) between the first and second transparent base layers, and comprises conductive portions. The conductive portions include thickness and are arranged to define open volumes adjacent the second transparent base layer. An insulating layer is formed between the first transparent base layer and the partially open conductive layer.    USE - Ultrasonic audio speaker for an electronic content device (claimed) such as laptop, tablet, smartphone, computer, TV, mobile device, camera and portable GPS unit. Can also be used for vehicle surfaces e.g. automobile mirrors, windows and dashboard panels, doors and windows of appliances e.g. conventional ovens, microwave ovens, toaster ovens, dishwashers and refrigerators, desktop telephones, physical fitness or exercise equipment, display cases e.g. department store, supermarket and deli and screens on equipment e.g. oscilloscopes, medical devices, printers and faxes.    ADVANTAGE - The speaker includes metalized films with sufficiently light-transmitting metallic coating so as to provide transparency without adversely affecting viewing of content through an emitter used to provide conductive sheets. The speaker ensures that a conductive mesh is oriented with respect to a pixel pattern in an underlying display to minimize or avoid appearance of an interference pattern i.e. moir, pattern. The speaker obtains resonance at optimal system performance to improve efficiency of the system and reduce heat produced by the system. The speaker forms an air gap to increase permeability and a number of turns in a primary winding and reduce heat generated by a pot core inductor without compromising shielding properties of a core and changing desired inductance of inductor element.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an electronic content device.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of a transparent parametric emitter.
