STABILIZED ELECTROMAGNETIC RESONANT ARMATURE TACTILE VIBRATOR

摘要

A resonant armature system (109, 114, 116) for generating a vibrating motion in response to an alternating excitation force comprises at least two planar suspension members (109), substantially parallel to each other and separated by a distance. The planar suspension member (109) comprises a plurality of independent planar spring members (112) arranged regularly about a central planar region (110) within a planar perimeter region (108). The resonant armature system (109, 114, 116) further comprises at least one movable mass (114) positioned between and coupled to the at least two planar suspension members (109) for resonating with the at least two planar suspension members (109) at a fundamental mode resonant frequency.
