<p>A loudspeaker can provide magnetic flux from polarity-aligned split magnets to drive voice coils and generate sound. The loudspeaker may have reduced stray magnetic fields and a BL curve with symmetric and linear characteristics. The loudspeaker can include a core, split magnets, a magnet housing, a core cap, and a voice coil gap formed between the magnet housing and the core cap. Magnetic flux produced by the split magnets may be combined, directed, and/or concentrated by the core cap and magnet housing within the voice coil gap. At least portions of a voice coil may be positioned within the voice coil gap and a diaphragm may be coupled to the voice coil. A bucking magnet assembly may contain a magnetic flux of the magnet structure to further improve performance. The bucking magnet assembly may include split magnets with an aligned polarity that is opposite the polarity of the magnet structure.</p> |
