Abstract
A loudspeaker cover (1) has a carrier frame (2) and a sound-permeable loudspeaker covering panel (3) attached to the carrier frame (2). A light exit opening (7) is formed between the loudspeaker covering panel (3) and the carrier frame (2). A lighting device (4) having at least one lightguide (40) and at least one lighting unit are arranged so that, during operation, light can be input into the lightguide (40). The lightguide (40) is arranged between the carrier frame (2) and the loudspeaker covering panel (3) and extends in the circumferential direction of the carrier frame (2). As a result, at least a portion of the light exiting a lateral surface of the lightguide (40) can propagate into the surroundings through the light exit opening (7). The carrier frame (2) is connected at least in certain sections in a materially joined fashion to the loudspeaker covering panel (3).
