ABSTRACT:
A diaphragm type magnetic speaker with conductor runs on the diaphragm, the conductor runs having a multiplicity of conductors arranged in a band in each run which confronts portions of two magnetized strips with front faces of opposite polarity and the space between such magnetized strips. The width of the band of conductors exceeds the width of the space between adjacent magnet strips and traverses the entire transverse portions of both of the adjacent magnetized strips from which the magnetic field for the conductor run emanates.
