发明名称 Planar-magnetic speakers with secondary magnetic structure
摘要 A planar magnetic transducer having enhanced magnetic structures which increases performance over a signal-ended device but mitigates some of the drawback of double ended devices, including a supporting structure, a diaphragm incorporating a coil conductor at least primary magnetic structure, and a secondary magnetic structure can be added, including mitigation of high frequency resonance and attenuation by providing a more open architecture, including spacing the magnets wider apart, configuring the inter-magnet spaces to provide better acoustic performance, using high-energy magnets, which magnets can be shaped to form at least a part of the shaped inter-magnet space.
