步骤 5
The Touchstone rear panel includes a secondary induction coil. The magnetic field generated by the base unit turns on and off rapidly, generating a magnetic pulse that is carefully tuned to the dimensions of the wire coil inside the phone. This oscillating magnetic field induces a current inside the phone, allowing the battery to be charged. Similar technology is used to transmit power to some battery-operated toothbrushes, razors, etc.
  • The Touchstone rear panel includes a secondary induction coil.

  • The magnetic field generated by the base unit turns on and off rapidly, generating a magnetic pulse that is carefully tuned to the dimensions of the wire coil inside the phone. This oscillating magnetic field induces a current inside the phone, allowing the battery to be charged.

  • Similar technology is used to transmit power to some battery-operated toothbrushes, razors, etc.

  • This explanation is an oversimplification of a very specific field of electrical engineering.

  • You'll note that the location of the induction coil is in the center of the device, well away from the antennas that line the perimeter of the phone.
