Abstract
Annular and/or rotational magnetic alignment components of magnetic alignment systems for wireless charging of devices can be enhanced with additional magnetic regions to provide increased attachment strength while preserving compatibility with other (baseline) magnetic alignment components that do not include the additional magnetic regions.
Claims20
An electronic device comprising:
- a housing having an interface surface;
- and
- an annular magnetic alignment component disposed within the housing and having an axis normal to the interface surface, the annular magnetic alignment component having an inner annular region with a magnetic orientation in a first radial direction and an outer annular region with a magnetic orientation in second radial direction opposite the first radial direction.
An electronic device, comprising:
- a housing having an interface surface;
- an annular magnetic alignment component disposed within the housing and having an axis normal to the interface surface, the annular magnetic alignment component comprising:
- an inner magnetized annular region having a magnetic polarity oriented in a first axial direction;
- a middle magnetized annular region having a magnetic polarity oriented in a second axial direction opposite the first axial direction;
- an outer magnetized annular region having a magnetic polarity oriented in the first axial direction;
- a first non-magnetized annular region disposed between the inner magnetized annular region and the middle magnetized annular region;
- and
- a second non-magnetized annular region disposed between the inner magnetized annular region and the middle magnetized annular region.
