In this embodiment, the control signal generating device 102 may be in the form of a button or a slider, and may be switched between a charging/discharging mode and an audio mode. For example, when the control signal generating device 102 sends a signal a distinguishable from a voice signal, on one hand, the charging and discharging device 101 in the earphone circuit structure enters a discharging state according to the signal a, and simultaneously the terminal device enters a charging state according to the signal a, so that the earphone side can charge to the terminal device side; on the other hand, the charging/discharging device may directly supply power to the electric device 103.

Further, the charging and discharging device 101 includes: a control circuit 1011, a step-up/down circuit 1012, and a storage battery 1013; wherein, the control circuit 1011 and the step-up/step-down circuit 1012 are both connected to the storage battery 1013; the control circuit 1011 is further connected to the control signal generating device 102 and the buck-boost circuit 1012; the buck-boost circuit 1012 is connected to the headset plug 107.
Specifically, a first terminal of the control circuit 1011 is connected to a first terminal of the storage battery, a second terminal of the control circuit 1011 is connected to a first terminal of the control signal generating device 102, and a third terminal of the control circuit 1011 is connected to a second terminal of the step-up/step-down circuit 1012. A first terminal of the step-up/down circuit 1012 is connected to a second terminal of the storage battery 1013, a third terminal of the step-up/down circuit 1012 is connected to the headphone plug 107 through a charging line, and a fourth terminal of the step-up/down circuit 1012 is connected to the headphone plug 107 through a ground line.
In this embodiment, the storage battery 1013 is used to store electric energy, that is, to supply electric energy when the charging and discharging device 101 is in a discharging state; when the charge and discharge device 101 is in the charged state, electric energy is stored.
