The invention relates to an electronic device. The electronic equipment comprises a conductive frame, a near field communication unit, an antenna coil and a tuning switch circuit. Wherein the conductive frame is provided with a breaking joint, and a first free end and a second free end of the conductive frame are formed at the position of the breaking joint; the near field communication unit is used for providing excitation current; the antenna coil and the conductive frame are used for jointly transmitting excitation current; the tuning switch circuit is connected in series between the first free end and the second free end of the breaking joint position; the tuning switch circuit is used for blocking excitation current at a working frequency point of the near field communication unit and transmitting feed current at a preset resonant frequency point; the feed current is used for exciting the conductive frame to radiate a preset radio frequency signal, and the preset resonant frequency point is higher than t
