Abstract
The transducer or transducers are mounted to the bottom of a U-frame carrying a coil between the legs; the coil is slipped onto and runs over a bar, facing two permanent magnets. One leg of the U-frame is suspended on leaf springs, being connected also to a base, so that the frame moves strictly linearly without lateral displacement. A similar spring mount may be connected to the other leg of the U-frame. The springs may have a U-configuration or an E-configuration.
