Abstract

357,286. Loud - s p e a k e r s. HAZELTINE CORPORATION, 15, Exchange Place, Jersey City, New Jersey, U.S.A.-(Assignees of Wheeler, H. A. ; 78, 22nd Street, Jackson Heights, New York, U.S.A.) July 1, 1930, No. 19934. Convention date, July 16, 1929. [Class 40 (iv).] In a push-pull amplifier operating without a grid biasing battery the output circuit may be connected to coils 5, 6 on the upper and lower limbs respectively of U-shaped polepieces of a loud-speaker of the kind in which the armature 11 moves in a plane parallel with the faces of the polepieces. Specifications 357,306, 358,132, and 358,887 are referred to.
