1879 C. Ader U.S. Patent 222,118 1/1 This invention relates more particularly to what may be called ‘magneto-telephones’, in contradistinction to carbon, water, and other telephones requiring the aid of a battery for operation. In this class of telephones the transmission and reproduction of speech depend upon the vibrations of an inductive armature in front of magnetic poles surrounded by bobbins, the vibrations of the armature inducing or responding to currents in the coils of the bobbins.
