LOUDSPEAKER COVER
The present invention relates to a loudspeaker cover comprising a light guide arranged for receiving light from a light source, wherein the light guide comprises at least one hole to allow sound to be emitted through the cover, and wherein the at least one hole is arranged for dispersing the received light out of the light guide. The holes in the light guide may e.g. be cylindrical, conical, double-conical, or formed as grooves. The invention further relates to a loudspeaker housing comprising such a loudspeaker cover, and an electronic entertainment device comprising such a loudspeaker cover. In a preferred embodiment, the loudspeaker cover is positioned adjacent to a display. In case light is emitted that matches the contents being shown on the periphery of the display, this effect is even further enhanced in that the colors are perceived as leaking out of the display onto the loudspeaker cover. The effect of the dispersed light is a larger virtual display and a more immersive viewing experience.
1 . A loudspeaker cover 11 comprising a light guide 12 arranged for receiving light from a light source 16 , wherein
the light guide 12 comprises at least one hole to allow sound to be emitted through the light guide 12 , and wherein the at least one hole is arranged for dispersing the received light out of the light guide 12 .
2 . A loudspeaker cover 11 according to claim 1 , wherein the hole is defined by a boundary surface 22 b of the light guide 12 that extends from a first side 12 a of the light guide 12 from where the sound is emitted to a second side of the light guide 12 onto which the sound is incident.
3 . A loudspeaker cover 11 according to claim 2 , wherein the boundary surface 22 b is substantially cylindrical.
4 . A loudspeaker cover 11 according to claim 2 , wherein the boundary surface is sloped with respect to the first side 12 a , such that in use the light is dispersed out mostly to the first side 12 a.
5 . A loudspeaker cover 11 according to claim 2 , wherein the at least one hole 26 is larger on the first side of the light guide 12 than on the second side of the light guide 12 .
6 . A loudspeaker cover 11 according to claim 5 , wherein the boundary surface is substantially conical.
7 . A loudspeaker cover 11 according to claim 2 , wherein the at least one hole 28 is at some point narrower than at the first and second side of the light guide 12 .
8 . A loudspeaker cover 11 according to claim 7 , wherein the hole volume has substantially the form of a double-cone.
9 . A loudspeaker cover 11 according to claim 1 , wherein the at least one hole 29 , as seen as from the outside front of the loudspeaker cover 11 , is formed as a groove.
10 . A loudspeaker cover 11 according to claim 2 , wherein the boundary surface at the line of intersection 32 between the boundary surface and the first or second side is rounded.
11 . A loudspeaker cover 11 according to claim 1 , wherein the light guide 12 has a substantially planar shape.
12 . A loudspeaker cover 11 according to claim 2 , wherein at least a part of the boundary surface is coated with a light-sensitive or a light-dispersing material.
13 . A loudspeaker cover 11 according to claim 1 , further comprising the light source 16 for supplying the light to the light guide 12 .
14 . A loudspeaker housing 10 comprising a loudspeaker cover 11 according to claim 1 .
