Abstract
An audio device is provided that is in electrical communication with a magnetic coil for the purpose of increasing magnetic field emissions generated by the device. The magnetic coil may be disposed on a flexible substrate in multi-turn and multi-layer format or disposed on a foldable flexible substrate in multi-turn and multi-layer format. Additionally, the magnetic coil may be disposed on the device's printed circuit board or the coil may be a freestanding, substrate-free coil assembly. The magnetic coil may be placed and secured in various locations within the device to maximize magnetic field emissions and minimize problems related to space limitations. The increased magnetic field results in a device that is hearing-aid compatible as defined by the Federal Communications Commission.
