Horn-loaded loudspeaker adapted to be mounted on a wall

摘要

There is a sound source 12, a throat 14 connecting the sound source 12 to a horn 16. The exterior of the horn 16)can be arranged on a wall 18. The throat 14 is designed such that the acoustic path from the sound source 12 to an interface 22 between the throat 14 and the horn 16 is shorter in a region close to the wall 18 than at a region that is remote from the wall 18. A variety of throat shapes are described (fig 2).
