“My invention relates to closure structure, as a cabinet confining and supporting a sound amplifying horn or the like in such a manner that the wall structure of the horn is not damped by the cabinet walls, or other cabinet structure and hence may vibrate freely under the influence of sound or signal waves passing therethrough without substantial transfer or vibratory impulses to said cabinet walls or other cabinet structures, and, more particularly, the amplifying horn aforesaid is so supported within the cabinet as to be readily removable as a unitary structure.
Further in accordance with my invention, there is provided a sound amplifying horn or radio speaker which is simple in construction, easy to assemble and cheap to manufacture, and which, preferably, is constructed of wood in sheet form, as veneer, which may be readily caused to assume the desired contour.” Arthur Atwater Kent
