Abstract

A curvilinear projection screen and acoustic system includes a curvilinear structural frame having a first side and a second side, a plurality of glass fiber reinforced gypsum (GRG) surface panels secured to the first side of the curvilinear structural frame, and a plurality of acoustic panels secured to the first side of the structural frame and interspersed between the plurality of GRG surface panels. In addition, the system includes a projection coating over the pluralities of GRG surface panels and acoustic panels to define a curvilinear projection surface.

Claims (37)

1. A curvilinear projection screen and acoustic system comprising:

a curvilinear structural frame having a first side and a second side;

a plurality of glass fiber reinforced gypsum (GRG) surface panels secured to the first side of the curvilinear structural frame;

a plurality of acoustic panels secured to the first side of the structural frame and interspersed between the plurality of GRG surface panels; and

a projection coating over the pluralities of GRG surface panels and acoustic panels to define a curvilinear projection surface.

2. The curvilinear projection screen and acoustic system of claim 1 , wherein the curvilinear projection surface is seamless.

3. The curvilinear projection screen and acoustic system of claim 1 , wherein each acoustic panel comprises a GRG panel having a randomized perforated portion therein configured to allow sound waves to pass.

4. The curvilinear projection screen and acoustic system of claim 3 , wherein the randomized perforated portion comprises carbon fiber.

5. The curvilinear projection screen and acoustic system of claim 3 , wherein the projection coating over the randomized perforated portion having a higher gain than over a remaining portion of the acoustic panel.

6. The curvilinear projection and acoustic system of claim 3 , wherein the randomized perforated portion comprises hydro formed aluminum sheeting.

7. The curvilinear projection and acoustic system of claim 3 , wherein the randomized perforated portion comprises hydro formed aluminum sheeting.

8. The curvilinear projection and acoustic system of claim 3 , further comprising a speaker installed behind the randomized perforated portion.

9. The curvilinear projection screen and acoustic system of claim 1 , wherein each GRG surface panel and acoustic panel having a curvature defined by an installation location on the curvilinear structural frame.

10. The curvilinear projection screen and acoustic system of claim 1 , wherein the curvilinear structural frame comprises a plurality of vertical trusses connected together by a plurality of horizontal purlins.

11. The curvilinear projection screen and acoustic system of claim 10 , wherein the plurality of horizontal purlins comprises wood configured to isolate sound from adjacent vertical trusses.

12. The curvilinear projection and acoustic system of claim 10 , wherein the plurality of vertical trusses comprises metal.

13. The curvilinear projection screen and acoustic system of claim 1 , wherein the pluralities of GRG surface panels and acoustic panels are cast in a plurality of molds, each mold having a different geometry and shape determined by an installation location on the curvilinear structural frame.

14. The curvilinear projection screen and acoustic system of claim 1 , wherein the pluralities of GRG surface panels and acoustic panels each comprising a taper around a perimeter filled with drywall compound to create a seamless joint between adjacent GRG surface panels and acoustic panels.

15. The curvilinear projection screen and acoustic system of claim 1 , wherein the pluralities of GRG surface panels and acoustic panels having a wood coring material embedded along a perimeter for mechanical fastening to the curvilinear structural frame.

16. The curvilinear projection screen and acoustic system of claim 1 , wherein a thickness of the plurality of GRG surface panels is reduced at a center portion thereof.

17. A curvilinear projection screen and acoustic system comprising:

at least one acoustic panel comprising a glass fiber reinforced gypsum (GRG) panel having a randomized perforated portion therein configured to allow sound waves to pass;

a projection coating over the at least one acoustic panel to define a projection surface; and

the at least one acoustic panel having a geometry and shape determined by an installation location on the projection surface.

18. The curvilinear projection screen and acoustic system of claim 17 , further comprising:

a plurality of vertical metal trusses;

a plurality of horizontal wood purlins connecting the plurality of vertical metal trusses;

a plurality of GRG surface panels secured to the plurality of horizontal wood purlins and having a curvature defined by an installation location on the curvilinear structural frame;

the at least one acoustic panel secured to the plurality of horizontal wood purlins and interspersed between the plurality of GRG surface panels; and

wherein each of the randomized perforated portions of the plurality of acoustic panels are resin infused in a mold.

19. The curvilinear projection screen and acoustic system of claim 17 , wherein the randomized perforated portion of the at least one acoustic panel being resin infused.

20. A method of constructing a curvilinear projection screen and acoustic system comprising:

connecting a plurality of vertical metal trusses using a plurality of horizontal wood purlins;

securing a plurality of glass fiber reinforced gypsum (GRG) surface panels to the plurality of horizontal wood purlins, the GRG surface panels having a curvature defined by an installation location on the curvilinear projection screen;

forming a plurality of acoustic panels with a randomized perforated portion therein configured to allow sound waves to pass;

securing the plurality of acoustic panels to the plurality of horizontal wood purlins between the plurality of GRG surface panels; and

installing a projection coating over the pluralities of GRG surface panels and acoustic panels to define a curvilinear and seamless projection surface.
