Abstract
A combined lighting and speaker device having a central longitudinal axis defining a forward and a rearward direction and a radially outward and a radially inward direction is provided. The device comprises a tweeter; a tweeter horn positioned radially outwardly of the tweeter; a speaker positioned rearward of the tweeter horn; and a light emitting diode, LED, assembly positioned radially outwardly of the tweeter. The LED assembly comprises one or more light emitting diodes, LEDs, and a lens having a forward surface. The tweeter horn has an inner edge in communication with an outer edge of the tweeter, so that the tweeter horn forms a guide to direct sound produced by the tweeter away from the speaker when in use. At least part of the tweeter horn is provided by the forward surface of the lens.
