ELECTRONIC DEVICE WITH FRAGMENTED MAGNETIC ATTACHMENT ASSEMBLY FOR WIRELESS CHARGING
The present disclosure is directed to an improved portable electronic device (e.g., a personal grooming device) having a fragmented (i.e., discontinuous) magnetic attachment assembly for supporting and aligning the device on a wireless charging pad or support pad for a wired recharging connection.
1 . An electronic device comprising:
a rechargeable battery;
a receiver coil adapted to wirelessly receive power from an electromagnetic field and generate current that is transmittable to the rechargeable battery; and
a magnetic attachment assembly comprising a plurality of magnets arranged in an annular shape without forming a complete annular array of magnets.
2 . The electronic device of claim 1 , the plurality of magnets consisting of two magnets which are diametrically opposed within the annular shape.
3 . The electronic device of claim 2 , the electronic device further comprising a housing including a contact surface, wherein the two magnets extend to lateral edges of the contact surface.
4 . The electronic device of claim 2 , wherein the two magnets are spaced apart by a distance that corresponds to the diameters of an industry-standard magnetic ring of a wireless charging device.
5 . The electronic device of claim 4 , wherein the distance is between 44-48 millimeters measured between respective inner edges of the two magnets.
6 . The electronic device of claim 4 , wherein the distance is approximately 46 millimeters measured between respective inner edges of the two magnets.
7 . The electronic device of claim 4 , wherein the distance is approximately 52-56 millimeters measured between respective outer edges of the two magnets.
8 . The electronic device of claim 4 , wherein the distance is approximately 54 millimeters measured between respective outer edges of the two magnets.
9 . The electronic device of claim 1 , the electronic device further comprising a device body having a profile that tapers in width between a top portion thereof and a bottom portion thereof.
10 . The electronic device of claim 1 , wherein each of the magnets of the plurality of magnets covers between 30 degrees and 90 degrees of an available 360 degrees of the annular shape.
11 . An electronic device comprising:
a rechargeable battery; and
a magnetic attachment assembly comprising a plurality of magnets arranged in an annular shape without forming a complete annular array of magnets.
12 . The electronic device of claim 11 , the plurality of magnets consisting of two magnets which are diametrically opposed within the annular shape.
13 . The electronic device of claim 12 , the electronic device further comprising a housing including a contact surface, wherein the two magnets extend to lateral edges of the contact surface.
14 . The electronic device of claim 12 , wherein the two magnets are spaced apart by a distance that corresponds to the diameters of an industry-standard magnetic ring of a wireless charging device.
15 . The electronic device of claim 14 , wherein the distance is between 44-48 millimeters measured between respective inner edges of the two magnets.
16 . The electronic device of claim 14 , wherein the distance is approximately 46 millimeters measured between respective inner edges of the two magnets.
17 . The electronic device of claim 14 , wherein the distance is approximately 52-56 millimeters measured between respective outer edges of the two magnets.
18 . The electronic device of claim 14 , wherein the distance is approximately 54 millimeters measured between respective outer edges of the two magnets.
19 . The electronic device of claim 11 , the electronic device further comprising a device body having a profile that tapers in width between a top portion thereof and a bottom portion thereof.
20 . The electronic device of claim 11 , wherein each of the magnets of the plurality of magnets covers between 30 degrees and 90 degrees of an available 360 degrees of the annular shape.
