Abstract
A demagnetization circuit for reducing interference in a mobile phone includes a wave filter, a demagnetization circuit and an audio playing circuit. The wave filter is configured to filter a received audio signal from the mobile phone. The wave filter includes an input that receives the audio signal, and an output. The demagnetization circuit is structured and arranged to generate an opposite magnetic field to that of the mobile phone to reduce pulse magnetic fields generated by the mobile phone.
