Inductive Power Transfer Using Acoustic or Haptic Devices
First Claim
1. A system for inductive power transfer, comprising:
- a first electronic device having a membrane;
a first coil associated with the first electronic device; and
a controller operable to change the first coil between a first mode and a second mode, wherein;
the first coil is operable in the first mode to move the membrane to produce one of sound or a haptic output or detect the sound using the membrane; and
the first coil is operable in the second mode to inductively transmit power to a second electronic device or inductively receive power from the second electronic device.

Abstract
A first electronic device includes a first coil that is operative in at least two modes. In a first mode, the first coil may be utilized to moves a membrane to produce one or more sound waves, register movement of a membrane to detect one or more sound waves, or generates one or more haptic outputs. In the second mode, the first coil may be used to inductively transmit power to and/or inductively receive power from a second coil included in a second electronic device. In various cases, the second coil may be a dedicated inductive power transmission coil. In other cases, the second coil may be capable of multimode operation similar to the first coil.
