The magnetic resistance pad plays a role in preventing the shell from generating eddy current during wireless charging so as to generate heat. The charging coil is made of gold, and has good charging efficiency. The magnetism increasing block plays a role in enhancing the middle magnetic field of the charging coil, and the charging efficiency is improved; the wireless communication antenna can enable the stimulator to communicate with the external machine, and plays a role in signal transmission. The four-pin feed-through piece is used for electrically connecting the charging coil and the wireless communication antenna into the built-in circuit of the stimulator and plays a role in preventing liquid.
The anti-collision cover that covers on the wireless communication part is placed directly over charging coil, four needle feed-through, wireless communication antenna, and when the stimulator was implanted and received the striking on human skull, the anti-collision cover can protect charging coil, four needle feed-through, wireless communication antenna to avoid the striking.
