Abstract

1,181,817. Electromagnetic horns. AUTOBRZDY JABLONEC NARODNI PODNIK. 31 May, 1967 [1 June. 1966], No. 25106/67. Heading G5J. In an electromagnetic horn the dimensions of the diaphragm and acoustic baffle are greater along one axis of symmetry than along another axis of symmetry normal to the first, e.g. as shown in Fig. 1, or the diaphragm and baffle may be elliptical.
