ABSTRACT:
An electro-acoustic transducer comprises a planar type diaphragm having a circular voice coil formed on its surface and a magnet plate assigned for magnetically biasing said voice coil, said circular voice coil having a plurality of circular turns formed with a pattern that the respective circular turns of the circular coil are concentric to each other in at least one half portions of these turns. This arrangement of transducer makes its assembling or the positioning of the voice coil and the magnet plate extremely easy without degrading the output capability of the transducer.
