Abstract

981,978. Motor-car horns. GENERAL MOTORS CORPORATION. June 13,1963 [July 13, 1962], No. 23594/63. Heading G5J. In an electromagnetically operated horn the sound waves generated by the central portion of the diaphragm 16 (Fig. 2) are launched into a spiral horn by reflection from a flat plate 36 positioned in the central chamber 30 of the horn at an acute angle to the axis of the diaphragm.
