Abstract
The armature of an electromagnetic transducer, extending through the polarizing flux between opposing permanent magnet pole faces, is snubbed to limit its shock-induced excursions normal to the directions of its extent and of the flux field. Such snubbing helps to protect the armature from plastic damage and accompanying shift of magnetic balance of the transducer upon the occurrence of a strong mechanical shock in an arbitrary direction.
