ABSTRACT:
An electromagnetic transducer utilizes flat permanently magnetized plates made of magnetically hard ceramic materials having thicknesses substantially less than the dimensions across the faces thereof. Electric signals may be applied through a coil adjacent one of the faces to cause a changing flux on the opposite face. This changing flux then may be utilized to produce electric outputs in an output coil or to drive a resiliently mounted magnet or shorted turn speaker coil. Conversely, changes may be induced in magnetic flux through the plate which are picked up by a coil on the other side of the plate and converted to electric signals which in turn may be applied to a suitable utilization device.
