Light and loudspeaker driver device

Abstract

A combined light and loudspeaker driver device 10 is suitable for mounting in, for example, a ceiling void. It comprises a housing 15 that supports a loudspeaker driver 20, a heat removal element 120, electronic components 25 and a light source 110. The heat removal element 120 includes a column 120a extending along a central longitudinal axis of the housing 15 to a base of the housing 15, where it meets a heat sink 40 formed around the central longitudinal axis to the rear of the housing 15. The light source 110 provides task lighting and is a source of heat. It is mounted on a front end of the column distal from the heat sink 40 at the base of the housing 15, so as to optimise conduction of heat away from the light source 110. The light source 110 is also positioned radially inwardly of a speaker diaphragm 130 also centred around the central longitudinal axis of the housing 15. The housing 15 is generally cup shaped and has side walls 15a. The interior of the housing side walls 15a is parallel with the central longitudinal axis of the housing 15 over the majority of the rearward depth thereof. This results in a large void behind the loudspeaker diaphragm 130, leading to improved sound.
