Annular magnetic alignment components with soft magnetic inserts

An electronic device comprising:

• a housing having a charging surface;
• a logic board disposed in the housing and having electronic circuit components disposed thereon;
• a magnetic alignment component disposed between the logic board and the charging surface such that at least a portion of the magnetic alignment component overlies a portion of the logic board, the magnetic alignment component comprising:
• a plurality of arcuate magnets arranged end-to end to define an annular shape, the arcuate magnets being made of a permanent magnetic material and having a magnetic orientation with a component in a radial direction, the arcuate magnets further having a uniform height in an axial direction transverse to the annular shape and being further arranged such that a gap in the annular shape is present between a pair of the arcuate magnets;
• and
• an arcuate insert disposed in the gap, the arcuate insert being made of a soft magnetic material, the arcuate insert having a height less than the uniform height of the arcuate magnets and an arcuate shape that fills the gap;
• and
• an inductive charging coil disposed inboard of and coaxial with the magnetic alignment component.

• a first insert disposed in the first gap, the first insert being made of a soft magnetic material, the first insert having a height less than the uniform height of the arcuate magnets and an arcuate shape that fills the first gap;
• and
• a second insert disposed in the second gap, the second insert being made of a soft magnetic material, the second insert having a height equal to the uniform height of the arcuate magnets and an arcuate shape that fills the second gap;
• and
• an inductive charging coil disposed inboard of and coaxial with the magnetic alignment component.
