Abstract: A device suitable for mounting in a ceiling aperture in a ceiling is provided. The device comprises a body having a front end and defining a longitudinal axis perpendicular to the front end. The device further comprises a flange that extends laterally beyond the body at the front end. The device further comprises one or more elastic members mounted on the body, each elastic member being configurable in a restrained position and an engaging position. The device further comprises a respective guide on the body associated with each elastic member, each guide being configured to receive a restraining member that urges the respective elastic member into the restrained position when the restraining member is inserted into the guide, and wherein the respective elastic member is released into the engaging position when the restraining member is removed from the guide, wherein each elastic member extends laterally beyond the body in the engaging position.

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.

Abstract: A kit of parts is provided comprising a light and/or loudspeaker fitting for a smart home system. The light and/or loudspeaker fitting comprises a lighting component and/or a loudspeaker; a sensor data input interface; and a processor. The kit of parts further comprises a sensor module comprising a sensor data output interface; and one or more sensors. The light and/or loudspeaker fitting and the sensor module comprise complementary fastening means configured to detachably couple the sensor module to the light and/or loudspeaker fitting so that the sensor data output interface of the sensor module is in communication with the sensor data input interface of the light and/or loudspeaker fitting when the sensor module is coupled to the light and/or loudspeaker fitting, so as to form a sensor interface between the sensor module and the light and/or loudspeaker fitting.
