ABSTRACT:
A loud-speaker is combined with a device for producing lighting speakers is covered by two discs provided with openings and, for example, being formed of a grating. The inner disc of the discs, which is facing the speaker cone is rotatable, whereas the outer disc is stationary. Rotation of the rotatable disc is driven either via a motor or via driver members fixed to the speaker cone of the loud-speaker which are actuated by transmission of the vibrations of the speaker cone to the rotating disc in order to provide rotating movement. Light sources for illuminating the surface of the inner or, respectively, outer disc, which is facing the light sources, are provided either within the speaker cone or outside of the loud-speaker. The lighting effects are then generated by the rotation of the inner disc.
