发明名称 Vibrating apparatus for low profile pagers
摘要 Vibratory alertion of received messages to subscribers of low profile pagers can be achieved in the following manner. On the substrate, or pager housing, attaching a pivotal post and a bumper a predetermined distance from the pivotal post. Attaching a substantially planar polarizable material to the pivotal post such that the polarizable material is substantially parallel to the substrate and when in motion, moves substantially parallel to the substrate. The polarizable material is set in motion by an excitation winding which provides a varying field.
