The bar has two edges, each positioned near one pole of the magnet to define a respective field across the gap, with the fields being oppositely polarized. An electromagnetic coil is positioned to ocsillate within the gap in response to an audio signal. The transducer is assembled with an unmagnetized magnet. The magnet is magnetized after assembly by application of an external magnetic field.
