Abstract

876,428. Diaphragms. HAWLEY PRODUCTS CO. Oct. 23, 1958 [Nov. 25, 1957], No. 33918/58. Drawings to Specification. Class 40 (4). A rectangular diaphragm for a loud-speaker is substantially the same as that described in Specification 876,427. The claims differ. There are slight modifications in the pattern of the strengthening ribs and the corrugated supporting strips at the edge of the diaphragm are formed integrally with the main body of the diaphragm.
