Abstract
A smart phone incorporating a T-coil unit is described. Selection between the output of the induction coil(s) of the unit and the analog output of the radio frequency section of smart phone can made by standard switches for the analog output of the smart phone. Alternatively, with control over the amplification of the induction coil output and the analog output of the radio frequency section, and over a comparator which receives both outputs, different modes of operations for the T-coil output and the analog output can be selected for the audio output of the smart phone. The T-coil unit can also be built as a smart phone dongle which notifies the user of the existence of induction loop signals.
