Title: Improvements in or relating to diaphragms more particularly for loud speakers and the like
IPC: H04R1/40
Filed: 1928-03-12
Abstract: 287,065. Siemens & Halske Akt.- Ges. March 12, 1927, [Convention date]. Diaphragms; loud-speakers; magnetic instruments. - A diaphragm for acoustic instruments comprises two or more rigid surfaces, each lying in the same plane hingedly connected together and to a stationary support. As shown in Fig. 2, two surfaces s<1>, s<2> stiffened by ribs or corrugations, which may be of rectangular cross-section, are connected together elastically, by a longitudinal corrugation w<2> which acts in the manner of a hinge and the surfaces are supported on a frame through the intermediary of the elastic corrugations w', w'. As applied to electromagnetic instruments, the - diaphragm is driven by armatures secured at points along the corrugation w<2>. In a modification, two flat surfaces connected together and supported by elastic material are used. Instead of stiffening the surfaces by corrugations &c., an additional layer of material may be employed. The diaphragm may be driven by a current conductor riveted or clamped to the diaphragm and' located in a magnetic field. As shown in Fig. 3, the corrugation w<2> clamps a conductor l which extends over the whole length of the diaphragm. In a modification, Fig 4, projections e<1>, e<2> on the bent portions of the surfaces s', s<2> forming the elastic joint are fitted together and bent so as to clamp the conductor l. Fig. 6 shows a further modification wherein a current carrying conductor l is placed around the central corrugation w<2> and a wire z which strengthens the diaphragm. In another arrangement, the conductor l is located inside a deep central corrugation and is held in position by cords &c. interlaced through slots in the corrugation. When the diaphragm is of metal., the conductor is insulated by paper, rubber, or a layer of oxide, and the diaphragm is provided with slots to eliminate eddy currents. Instead of a separate conductor, the central corrugation may act as the current-carrying conductor. Elastic threads &c. connected to the central corrugation and the supporting frame are provided to facilitate axial movement, which may be damped by the provision of an apertured air chamber on one side of the diaphragm. The rigidity of the partial surfaces of the diaphragm is such that the speed of wave propagation is approximately equal to the velocity of sound in air. Fig. 8 shows a loud-speaker comprising four diaphragms d<1> - - d<4> operated by electromagnets m<1> - - m<4>.

Abstract: 982,808. Stamping. SOC. METALLURGIQUE DE GERZAT. Feb. 27, 1963 [Feb. 28, 1962], No. 7911/63. Heading B3Q. [Also in Division B5] A method of shaping integral convex hollow bodies comprises preparing a rough blank having a surface the same as the object to be made but with larger axial and smaller lateral dimensions and having an opening at one axial end thereof, filling the blank with liquid and subjecting it to an axial pressurising action between a pair of half matrices shaped to correspond to the upper and lower portions of the object to be made having contacting surfaces coincident with the equator thereof so that an axial compressive action shortens the blank whilst the liquid expands the wall radially without any appreciable change in wall thickness into contact with the internal faces of the matrices when the latter are in contact. A blank 50, of e.g. aluminium or alloys thereof or plastic, having an opening 43 and a lower cylindrical portion is filled with liquid, e.g. oil or water, and located in a lower matrix 102, an upper matrix 104 fixed to a cylinder 107 of an hydraulic press 106 and having a bore 114, seal 115 and a non-return spring valve 118 is lowered to engage and axially compress the blank and the liquid therein to effect expansion of the blank until the matrices are completely closed together. A headed shaft 110 of the press 106 continues to move downwardly within the cylinder 107 to compress the liquid therein until a pressure release valve 121 is operated by which time complete expansion of the blank against the inner faces of the matrices will have been effected. Retraction of the cylinder 107 and shaft 110 causes replacement liquid to be drawn into the cylinder through a supply inlet 119 therein. The blank may be initially formed from a cylindrical tube 41 having a diameter 20% smaller than that of the finally produced sphere 30 and a portion 42, the diameter of which is substantially equal to that of the sphere. A sphere 10 having an opening 11 may be similarly formed. The blank may have a variable wall thickness.
