Abstract
714,006. Loudspeaker diaphragms. SOC. AUDAX. June 3, 1952 [Sept. 5, 1951], No. 14030/52. Class 40 (4) The periphery of a loudspeaker diaphragm made of moulded paper or moulded textile material is impregnated with a plastic to increase its resiliency. The diaphragm C is removably mounted between a swivel D and a face plate F, the assembly being rotatable about bearings E, G. A bath L of plastic substance based on natural gum or synthetic resin is adjustable vertically. The diaphragm dips into the plastic sub-' stance and is rotated, excess plastic being wiped off by scrapers V, V<SP>1</SP>. The spider may be treated in a similar manner.
