Abstract
A receiver assembly includes a housing having a fixed housing portion and a shiftable housing portion cooperating to define a hollow cavity. A flexible membrane secured between the fixed housing portion and the shiftable housing portion and adapted to allow relative motion between the fixed and shiftable housing portions. The receiver assembly further includes a magnetic motor assembly including a displaceable drive rod; and a link assembly having a first end fixedly attached to an inner surface of the shiftable housing and a second end coupled to the drive rod. The link assembly translates the shiftable housing portion relative to the fixed housing portion in response to the displacement of the drive rod.
