A planar magnetic transducer (10) having enhanced magnetic structures which increases performance over a single-ended device but mitigates some of the drawbacks of double ended devices, including a supporting structure (30a, 30b), a diaphragm (21) incorporating a coil conductor (27) at least a primar y magnetic structure (35a-g), and a secondary magnetic structure (36a-e) can b e added, including mitigation of high-frequency resonance and attenuation by providing a more open architecture, including spacing the magnets wider apar t, configuring the inter-magnet spaces to provide better acoustic performance, using high-energy magnets, which magnets can be shaped to form at least a pa rt of the shaped inter-magnet space, all of which are directed to obtaining a more efficient and less costly use of magnet material to achieve enhanced performance.
