Claim 10:
11. A system for providing visual and acoustical signals, comprising:
a light emitting display having light sources and a display surface, and perforations extending perpendicularly to the display surface, at least one loudspeaker having a displacement amplitude and a frequency range of 5 kHz to 30 kHz,
wherein each of the perforations comprise a conical shape and are disposed between the light sources, wherein an amount of open surface caused by each of the perforations is smaller on the display surface in which the light sources are disposed than on a back side of the light emitting display positioned toward the at least one loudspeaker, wherein the at least one loudspeaker is placed immediately behind the display so that when the at least one loudspeaker is positioned at a maximum displacement amplitude, the at least one loudspeaker is in contact with the display.
