ABSTRACT:
A push-pull magnetic-planar acoustic transducer provides easy field replacement of a diaphragm. Push-pull magnetic-planar acoustic transducers are known for the relative vulnerability of their diaphragms to damage. Replacement of the transducers in the field as been problematic because of the high repulsive force between the front and back panels and the need to obtain even tension across the diaphragm. The push-pull transducer assembly incorporates an edge hinge on which the panels can be pivoted to bring the panels into facing positions and a plurality of set screws to be fitted around the perimeter of the panels allowing essentially flat closure of the panels on one another to a working spacing engaging the diaphragm.
