Abstract
A system and method for providing visual and acoustical signals is described, comprising a light emitting display having light sources and a display surface, and perforations extending perpendicularly to the display surface and disposed between the light sources, at least one loudspeaker positioned behind the light emitting display. The perforations comprise a non-cylindrical shape. The openings on the side of the light sources occupies at least 5% of the area of the light emitting display for sound passing through.
Claims22
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 and disposed between the light sources, and
- at least one loudspeaker positioned behind the light emitting display,
- wherein the perforations comprise a non-cylindrical shape, wherein the amount of open surface caused by the perforations is smaller on the side of the light sources than on the counter side and wherein the openings of the perforations on the side of the light sources occupy at least 5% of the area of the light emitting display for sound passing through.
(canceled)
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 to 30 kHz,
- wherein the perforations comprise a conical shape and are disposed between the light sources wherein the amount of open surface caused by the perforations is smaller on the side of the light sources than on the counter side, wherein the at least one loudspeaker is placed immediately behind the display so that when it is positioned at its maximum displacement amplitude, it is in contact with the display.
(canceled)
A system for providing visual and acoustical signals, comprising a light emitting display having light sources, a display surface and perforations extending perpendicularly to the display surface,
- at least one loudspeaker having a displacement amplitude and a frequency range of 0.1 kHz to less than 5 kHz,
- wherein the perforations comprise a conical shape and are disposed between the light sources, wherein the amount of open surface caused by the perforations is smaller on the side of the light sources than on the counter side, wherein the at least one loudspeaker is placed immediately behind the display so that when it is positioned at its maximum displacement amplitude, it separated from the display by 1 mm to 15 cm.
(canceled)
A method for providing visual and acoustical signals, using a light emitting display having light sources and a display surface, and perforations extending perpendicularly to the display surface and disposed between the light sources, wherein the perforations comprise a non-cylindrical shape, wherein the amount of open surface caused by the perforations is smaller on the side of the light sources than on the counter side and wherein the opening of the perforations on the side of the light sources occupy at least 5% of the area of the light emitting display for sound passing through further comprising placing at least one loudspeaker behind the light emitting display.
A method 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, wherein the perforations comprise a conical shape and are disposed between the light sources, the method comprising
- placing at least one loudspeaker immediately behind the display, the at least one loudspeaker having a displacement amplitude so that when it is positioned at its maximum displacement amplitude, this is in contact with the display, the at least one loudspeaker emitting sound at a frequency range of 5 to 30 kHz.
