Abstract

206,305. Newcombe, W. H. Sept. 20, 1922. Cases with internal horns. -In a gramophone of the enclosed horn type, in which a long narrow soundconduit connects the tonearm to the body of the horn, the sound-amplifier is suspended by fastening the 'body portion 1 at its front upper edge by means of lugs 10 to the wall of the cabinet, and directly connecting the sound-conduit 3 to the tonearm 5. The member 3 may, as shown, project into the body 1. Instead of being doubled back on itself as shown, the soundconduit 3 may be straight, or may have one or more coils.
