In the utility model, the key 3 controls the PIN to output pulse voltage so as to enable the TWS Bluetooth headset 2 to be communicated with the charging box 1, and then the duration time of the key 3 is detected by using a pulse voltage duration time detection module, so that the TWS Bluetooth headset 2 executes a pairing instruction or clears a pairing record; the utility model can complete the emptying pairing record of the TWS Bluetooth headset 2 and the pairing connection with the terminal equipment on the charging box 1, thereby avoiding the complexity of the operation that the existing TWS Bluetooth headset needs to manually empty the pairing record individually and optimizing the simplicity of the pairing operation of the TWS Bluetooth headset.
Further, the charging box 1 includes a main control board, a switch detection module for detecting whether the charging box 1 is in an open state and a key detection module for detecting whether the key 3 is in a pressed state, the switch detection module, the key detection module and the PIN are respectively connected with the main control board through a circuit, wherein the circuit diagram of the main control board is as shown in fig. 3, and the main control board controls the PIN to output a pulse voltage or a direct current voltage according to the detection results of the key detection module and the switch detection module.
Specifically, the following two cases can be classified:
(1) when the detection results of the key detection module and the switch detection module are yes, namely the key 3 is detected to be in a pressed state and the charging box 1 is detected to be in an opened state, the main control board controls the PIN PIN to output pulse voltage.
(2) When the detection result of the switch detection module is negative, namely the charging box 1 is in the on state, no matter whether the key 3 is pressed down, the main control board controls the PIN PIN to output direct current voltage so as to charge the TWS Bluetooth headset 2 or keep the TWS Bluetooth headset 2 in the off state.
In the embodiment, when the charging box 1 is closed, the charging box 1 always controls the PIN to have direct-current voltage output, and at the moment, the operation of pressing the key 3 by a user is invalid; specifically, when the TWS Bluetooth headset 2 is in a non-full power state, the PIN outputs DC 5V voltage to charge the TWS Bluetooth headset 2; and when the TWS Bluetooth headset 2 is in a full power state, the PIN PIN outputs DC 3.7V voltage to the TWS Bluetooth headset 2, so that the TWS Bluetooth headset 2 keeps a power-off state. When a user opens the charging box 1, the charging box 1 is automatically powered off, namely the voltage difference output by the PIN needle is 0, the TWS Bluetooth headset 2 is automatically started at the moment, and meanwhile, the host and the slave are automatically in wireless connection; at this time, if the user presses the key 3, the PIN outputs a pulse voltage to communicate with the TWS bluetooth headset 2.
In this embodiment, the model of the main control board in the charging box is main control MCU SS809, and the model of the main control chip is main control chip BES230 iU.
Further, the charging box 1 further comprises a power detection module for detecting whether a power supply in the TWS bluetooth headset 2 is in a full power state, and the power detection module is electrically connected with the main control board.
