An electro-acoustic transducer having a spherically shaped diaphragm for the generation of sound in an omnidirectional capacity. The spherically shaped diaphragm is constituted of two identical diaphragm halves open at the hemispherical apexes and connected at the equatorial diameter via inwardly extending reinforcing flanges. The spherically shaped unit is driven by magnetic arrangement(s) located within the interior of the spherically shaped diaphragm. The moving coil(s) of the magnetic arrangement(s) are connected to the diaphragm via rigid conical projections from the magnetic arangement(s). The rigid conical projections communicate the movements of the coil(s) to the diaphragm. The diaphragm travels in a north-south direction during operation such that the sound generated will have omnidirectional characteristics with greater pressure in the north-south direction. A wave-guide shaped base plate channels some of the waves from the north-south direction to the east-west direction to increase omnidirectional dispersion of sound. The manufacturing process renders easy assembly of the components of the transducer.
