Abstract

243,837. Wilhelm, F. Sept. 18, 1924. Diaphragms not associated with tone-arms; horns, arranging and supporting. - In a soundreproducing device such as a talking machine comprising a diaphragm associated with a resonance box, the diaphragm or its carrying frame is mounted directly on one sounding wall of the box, a sound post, strut or the like being interposed between the diaphragm and the opposite sounding wall. As shown applied to a loudspeaker, the box comprises two walls 9, 16 the diaphragm 5 carried by the frame 12 being secured to the wall 9.
