  • the light-reflecting, flat-shaped cover is formed as a light or white fleece.
  • a colored design of the cover preferably bright light is reflected and used for color staging of the speaker.
  • the light source is designed as an annular light guide, which is arranged in an edge region of the light-reflecting, areal cover, facing the speaker grille.
  • the arrangement of the annular light guide in the edge region of the cover reduces the space between the speaker and speaker grille and allows a compact design of the speaker.
  • the light guide and the cover are fastened to a common fixing element.
  • the space required for the device is further reduced because it can be dispensed with further fasteners for attachment of optical fiber and cover.
  • the fixing element is designed as a fixing ring, which encloses the annular light guide, wherein an edge of the light-reflecting cover is attached to the fixing ring.
  • the cover can be well clamped between the speaker and speaker grille, so that a more reliable reflection of the light emitted through the annular light guide light in the direction of the speaker grille is possible.
  • the use of a fixing ring simultaneously reduces the space required for the speaker unit space.
  • the light guide is provided with an LED coupling element. connected, by which light is fed into the light guide.
  • LED coupling element is attachable to the outside of the speaker element, this can be coupled at any point of the speaker unit, depending on how it allow the space at the installation of the speaker unit.

  • Fig. 1 shows a detail of a motor vehicle 1, in which an interior view of the windshield 3 is shown. Below the windshield 3, a dashboard 5 is arranged, on which the steering wheel 7 and the instrument panel 9 are fixed. On both sides of the instrument panel 5 trim parts 11 are present, which include a speaker grille 13. Behind this trim part 11 with the speaker grille 13, a loudspeaker 15 is disposed within the dashboard 5, as shown in Fig. 2. Between the speaker 15 and the speaker grille 13, a light or white web 17 is positioned, which is flat and covers the speaker 15. This web 17 is attached to a fixing ring 19, wherein the ends of the web 7 are glued to the fixing ring 19, for example.

  • the fixing ring 19 encloses an annular light ladder 21 which illuminates the web 17. Since the nonwoven 17 has a reflecting surface in the direction of the loudspeaker grille 13, the light radiated from the annular light guide 21 is reflected on the nonwoven 17 and the reflected rays are supplied to the loudspeaker grating 13. In this way, not only the sound of the loudspeaker 15 but also the light rays reflected by the nonwoven 17 pass through the loudspeaker grille 13 and serve to colorize the loudspeaker 15.
  • the structure of the lighting element 17, 19, 21 is shown in a front view 'again in Fig. 3. It can be seen that the fixing ring 19 rests on the non-woven 17, which has a circular surface, which in turn carries the annular light guide 21.
  • the annular light guide 21 is contacted with an LED coupling element 23, which couples the light generated by an LED 25 in the annular light guide 21 and thus allows irradiation of the web 17.
