Abstract
Techniques for implementing a multifunction device with battery charging and haptic feedback capabilities are described. An example of an electronic device includes a multifunction charger and a control circuitry configured to activate one of a plurality of available operating modes of the multifunction charger. The plurality of operating modes includes a wireless charging mode and a haptic feedback mode.
Claims25
An electronic device comprising:
- a processor;
- a memory device comprising instructions to be executed by the processor;
- a battery to provide electrical power to the processor and the memory device;
- a multifunction charger;
- and
- control circuitry configured to activate one of a plurality of available operating modes of the multifunction charger, wherein the plurality of operating modes of the multifunction charger comprises a wireless charging mode and a haptic feedback mode.
A multifunction charger with a plurality of operating modes, comprising:
- an enclosure;
- a first conductive winding fixedly disposed on an inner wall of the enclosure;
- a magnetic core suspended inside the enclosure by a spring;
- a second conductive winding surrounding the magnetic core;
- wherein a resonant frequency of the magnetic core and the spring or a plurality of springs is tuned for haptic effects and vibrational energy harvesting.
A method of operating a multifunction charger comprising a stationary winding and a movable winding, the movable winding disposed around a magnetic core, the method comprising:
- identifying a mode from a plurality of available operating modes comprising a wireless charging mode, a haptic feedback mode, and a vibrational energy harvesting mode;
- and
- selecting a coupling configuration to implement the identified mode.
