A glass body or a component of the loudspeaker has a visual sign. The lighting unit illuminates the glass body or the component of the loudspeaker to showcase the visual sign using lighting. ## Claims ### Claim 1 A loudspeaker arrangement comprising: a loudspeaker; a loudspeaker cover comprising a glass body, wherein the loudspeaker is arranged behind the loudspeaker cover and faces a rear side of the loudspeaker cover; a diffuser arranged between the loudspeaker and the glass body, wherein the diffuser or the glass body has a visual sign; a support structure, formed at least in sections from a transparent or translucent material, arranged on the rear side of the loudspeaker cover, wherein the support structure is configured to stabilize the loudspeaker cover against mechanical influences and has a plurality of light decoupling structures; and a lighting unit comprising a light quide element surrounding an edge of the support structure and at least one light coupling element coupled to the light quide element, wherein the lighting unit is configured to illuminate, using lighting, the glass body or the diffuser to showcase the visual sign, and wherein the light coupled into the light guide element and emitted by the at least one light coupling element emerges directly or indirectly, via the plurality of light decoupling structures of the support structure, in a region of the glass body or via the glass body. ### Claim 2 (depends on 1) The loudspeaker arrangement of claim 1, wherein the visual sign is arranged on an underside of the glass body, on an upper side of the glass body, or in an interior of the glass body and the visual sign is formed printing, foil, indentation, embossing, or matte finishing. ### Claim 3 (depends on 1) The loudspeaker arrangement of claim 1, wherein the visual sign is arranged on an upper side of the diffuser and the visual sign is formed by printing, foil, indentation, embossing, or matte finishing. ### Claim 4 (depends on 1) The loudspeaker arrangement of claim 1, wherein the sections formed from the transparent or translucent material of the support structure are arranged in such a way that coupled light exclusively emerges directly or indirectly via the glass body of the loudspeaker cover. ### Claim 5 (depends on 1) The loudspeaker arrangement of claim 1, wherein the light coupling element is coupled to a control unit configured to switch the at least one light coupling element on and off, or to control a brightness, a color, or a frequency of emitted light. ### Claim 6 (depends on 1) The loudspeaker arrangement of claim 1, wherein the glass body is arranged in a holder arranged on the diffuser. ### Claim 7 (depends on 1) The loudspeaker arrangement of claim 1, wherein the light emitted by the at least one light coupling element and coupled to the light guide element exits directly or indirectly via a perforation of the loudspeaker cover. ### Claim 8 A vehicle comprising: a loudspeaker arrangement, which comprises a loudspeaker; a loudspeaker cover comprising a glass body, wherein the loudspeaker is arranged behind the loudspeaker cover and faces a rear side of the loudspeaker cover; a diffuser arranged between the loudspeaker and the glass body, wherein the diffuser or the glass body has a visual sign; a support structure, formed at least in sections from a transparent or translucent material, arranged on the rear side of the loudspeaker cover, wherein the support structure is configured to stabilize the loudspeaker cover against mechanical influences and has a plurality of light decoupling structures; and a lighting unit comprising a light quide element surrounding an edge of the support structure and at least one light coupling element coupled to the light guide element, wherein the lighting unit is configured to illuminate, using lighting, the glass body or the diffuser to showcase the visual sign, and wherein the light coupled into the light quide element and emitted by the at least one light coupling element emerges directly or indirectly, via the plurality of light decoupling structures of the support structure, in a region of the glass body or via the glass body. ### Claim 9 (depends on 8) The vehicle of claim 8, wherein the visual sign is arranged on an underside of the glass body, on an upper side of the glass body, or in an interior of the glass body and the visual sign is formed printing, foil, indentation, embossing, or matte finishing. ### Claim 10 (depends on 8) The vehicle of claim 8, wherein the visual sign is arranged on an upper side of the diffuser and the visual sign is formed by printing, foil, indentation, embossing, or matte finishing. ### Claim 11 (depends on 8) The vehicle of claim 8, wherein the sections formed from the transparent or translucent material of the support structure are arranged in such a way that coupled light exclusively emerges directly or indirectly via the glass body of the loudspeaker cover. ### Claim 12 (depends on 8) The vehicle of claim 8, wherein the light coupling element is coupled to a control unit configured to switch the at least one light coupling element on and off, or to control a brightness, a color, or a frequency of emitted light. ### Claim 13 (depends on 8) The vehicle of claim 8, wherein the glass body is arranged in a holder arranged on the diffuser. ### Claim 14 (depends on 8) The vehicle of claim 8, wherein the light emitted by the at least one light coupling element and coupled to the light guide element exits directly or indirectly via a perforation of the loudspeaker cover.
