ABSTRACT:
A dual mode transducer (600) includes an electromagnetic driver (604), an armature including upper and lower substantially parallel planar suspension members (610) coupled to the driver (604), and a magnetic motional mass (616) suspended between the suspension members (610). The suspension members (610) include a plurality of independent planar non-linear spring members (612) arranged regularly about the central region (614) within a perimeter region (608). The spring members (612) are defined by members having maximum opposing widths tapering to minimum opposing widths at midpoints thereon, the maximum opposing widths are coupled to the central region (614) and to the perimeter region (608). The motional mass (616) couples to the electromagnetic field which alternately moves the motional mass (616), the movement being transformed through the spring members (612) and the driver (604) into motional energy. A soundboard (1014), coupled to the driver (604), couples the motional energy to a user.
