发明名称 Loudspeaker magnet having a channel
摘要 A transducer magnet for a low profile loudspeaker transducer is provided having a voice coil, surround suspension, diaphragm, and top plate. The transducer magnet may include a first magnet assembly, including an annular outer magnet having an outer perimeter, an outer diameter and an inner diameter. The inner diameter defines a vacant circular center within the annular outer magnet, and the difference in length between the diameter of the circular inner magnet and the inner diameter of annular outer magnet define an annular first magnet assembly air gap. The annular outer magnet includes one or more channels extending inwardly from the outer perimeter of the annular outer magnet to the first magnet assembly air gap, which is configured to receive the voice coil. The channels are configured to pass hookup wires from the voice coil to an external device from the transducer magnet.
