Magnetic docking base for handset
View Patent ↗Novel tools and techniques are described for coupling electronic devices with docking stations. In one aspect, a coupling system comprises a first material in the docking station and a second material in the electronic device. The first material and the second material may each comprise at least one magnet and/or at least one ferromagnetic material that interact magnetically to align the electronic device in an appropriate position with respect to the docking station. The docking station comprises a first set of electrical contacts and the electronic device comprises a second set of electrical contacts. When in the appropriate position, the first set of electrical contacts electrically couples with the second set of electrical contacts. The shapes of the first and second electrical contacts, and the polarities of the magnets/ferromagnetic materials, may be configured to facilitate electrical coupling while avoiding mismatching of the positive/negative terminals of the electrical contacts.
