Abstract
A hearing aid compatible mobile electronic device is provided. The hearing aid compatible mobile electronic device includes a wireless communication unit including a power amplification module, a power source configured to transfer a first current to the power amplification module through a sending end thereof and to receive a second current from the power amplification module through a ground terminal thereof, a line unit connected between the power amplification module and the power source and including a first line through which the first current flows and a second line through which the second current flows in an opposite direction to the first current, and a receiver configured to generate a magnetic signal for hearing aid compatibility and to receive a first magnetic field generated by the first current and a second magnetic field generated by the second current.
