The mobile phone generates an electric signal when playing a prescription audio file, transmits the electric signal to the power amplifier through the earphone interface, amplifies the power of the electric signal through the power amplifier, transmits the electric signal to an affected part through the electrode, and performs intermediate frequency physiotherapy. In the process, the user can adjust the volume of the mobile phone according to the bearing capacity of the user on the medium-frequency electric stimulation, and further the adjustment of the output stimulation intensity of the medium-frequency electric stimulation is realized.
Here, the mobile phone stores 24 prescription audio files in advance, and is generated by a generation system based on the prescription audio files. The generation system of the prescription audio file comprises an intermediate frequency physiotherapy equipment body, a recording matching circuit and a mobile phone.
