Abstract

3720. De la Rue, E. March 30. Diaphragms.-A sound-box diaphragm f has a U or V peripheral corrugation k, and is held on one side only of one gasket g by the pressure of the screw connexion h of the stylus - bar. By this mounting, the pressure of the gasket on the diaphragm is oblique with the plane of the diaphragm, instead of at right-angles thereto as usual. The tie-rod e may be replaced by a flexible ligament of silk, gut, or the like.
