Sound generating apparatus

摘要

Sound generating apparatus adapted for use in a combination light fixture and acoustic conditioner assembly for use in open plan offices provides means for masking external sounds in the vicinity of the light fixture and acoustic conditioner assembly and includes a reflector (18) positioned so that sound waves from a sound emitter (22) contacting the reflector are dispersed in a plurality of directions due to the concavity of the reflector and non-uniform undulations (76) therein and eventually contact the ceiling where they are further reflected and spread. Dispersion of sound waves in this manner provides a pleasant, unintelligible sound which masks external sounds that might otherwise distract occupants of the office.
