First claim

What is claimed is:

an energy device comprising one or more conductive diaphragms mounted between one or more pairs of electrically conductive planes comprising a plurality of apertures;
wherein the energy device is located adjacent to the energy surface and extends across at least a portion of a surface of the energy surface, the plurality of apertures being substantially coincident with the plurality of first energy locations;
wherein the one or more conductive diaphragms are substantially transmissive of the first energy directed from the energy surface; and
wherein the one or more pairs of electrically conductive planes are configured to move the one or more conductive diaphragms to thereby produce a second energy directed from the energy device.

2. The energy directing system of claim 1 , wherein the energy surface is a display wall and the plurality of energy locations are a plurality of light sources, the first energy comprising light energy; and
wherein the energy device is an electrostatic speaker, and the second energy comprises sound waves.

3. The energy directing system of claim 2 , wherein the plurality of light sources comprise LED light sources.

4. An energy system comprising:
an array of waveguides, each waveguide comprising one or more elements disposed on separate substrates, each waveguide comprising at least one aperture;
an energy device comprising one or more conductive diaphragms mounted between one or more pairs of electrically conductive planes comprising a plurality of energy apertures;
wherein the energy device is configured such that, as a voltage is applied across the one or more pairs of electrically conductive planes, the one or more pairs of electrically conductive planes induce a movement of the one or more conductive diaphragms, thereby producing an energy;
wherein the plurality of energy apertures are substantially coincident with the plurality of waveguide apertures; and
wherein the energy device is configured to be accommodated between the separate substrates of the array of waveguides.

5. The energy system of claim 4 , wherein the conductive planes disposed between the elements of the waveguide inhibit energy propagation between adjacent waveguides.

6. An energy directing system, the system comprising:
an energy source system configured to produce at least a first energy at a plurality of energy locations;
an array of waveguides, wherein each waveguide of the array of waveguides is configured to receive the at least first energy from a corresponding subset of the plurality of energy locations, wherein each energy location of the subset of the plurality of energy locations substantially fills an aperture of each waveguide, and each waveguide directs the at least first energy along a plurality of propagation paths, each propagation path of the plurality of propagation paths determined at least by the location of the corresponding energy location;
an energy device comprising one or more conductive diaphragms mounted between one or more pairs of electrically conductive planes comprising a plurality of apertures;
wherein the energy device is located adjacent to the array of waveguides and extends across at least a portion of the array of waveguides, such that the plurality of apertures of the energy device are substantially coincident with the apertures of the array of waveguides;
wherein the one or more conductive diaphragms are substantially transmissive of the at least first energy directed along the plurality of propagation paths; and
wherein the energy device is configured such that, as a voltage is applied across the one or more pairs of electrically conductive planes, the one or more pairs of electrically conductive planes induce a movement of the one or more conductive diaphragms, thereby producing a second energy directed in coordination with the plurality of propagation paths.

7. The energy directing system of claim 6 , wherein the plurality of propagation paths of each waveguide of the array of waveguides combine to form a 4D energy field of the at least first energy.

8. The energy directing system of claim 6 , wherein the second energy comprises acoustic energy.

9. The energy directing system of claim 6 , wherein the one or more conductive planes of the energy device are configured to inhibit propagation of the at least first energy, whereby any portion of the at least first energy from the corresponding subset of the plurality of energy locations associated with a waveguide that does not pass through an aperture of the waveguide is substantially absorbed.

10. The energy directing system of claim 6 , the energy device comprising a plurality of pairs of conductive planes, each pair configured to operate independently of one another.

11. The energy directing system of claim 10 , wherein the second energy is sound energy.

12. The energy directing system of claim 10 , wherein the second energy is ultrasound energy.

13. The energy directing system of claim 12 , wherein the energy device is operable to produce an acoustic energy field that forms at least one volumetric tactile surface in coordination with the plurality of propagation paths of the at least first energy.

14. The energy directing system of claim 13 , wherein the plurality of propagation paths of each waveguide of the array of waveguides combine to form a 4D energy field of the at least first energy, and wherein the volumetric tactile surface is produced in coordination with the 4D energy field.
