Abstract
The present invention relates to an electromagnetic vibrator of variable reluctance type, according to a new principle which provides higher efficiency, smaller dimension, and higher reliability compared to known technology. This has been obtained by the magnetic signal flux around the coil is closed through a bobbin body and a yoke and through air gaps formed between bobbin body and yoke(s) where a static flux from one or more of the permanent magnets and the signal flux cooperates so that static forces are outbalanced and so that axial signal forces are generated. The new vibrator principle has been names: Balanced Electromagnetic Separation Transducer (BEST).
