Title:
任意の機械的な衝撃に対して改善した耐性を有する磁気トランスデューサー
Document Type and Number:
Japanese Patent JP2004529767
Kind Code:
A
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.
