Therefore, the Bluetooth equipment can play the stereo audio after receiving the stereo audio, and the stereo playing effect of the Bluetooth equipment is realized.

Illustratively, the bluetooth device is a bluetooth headset 300, and the bluetooth headset 300 includes a left-ear headset and a right-ear headset.

It is understood that in the charging state, assuming that the bluetooth headset 300 is not in the charging chamber of the bluetooth headset charging box 200, the charging current flows into the control module 204 through the charging interface 202 and flows into the battery 201 via the control module 204. Assuming the bluetooth headset 300 is in the charging chamber of the bluetooth headset charging box 200, the charging current flows into the control module 204 through the charging interface 202 and flows into the bluetooth headset 300 via the control module 204.

In a communication state, the bluetooth headset charging box 200 is electrically connected to the terminal 100, and the bluetooth headset charging box 200 is bluetooth connected to the bluetooth headset 300. The audio information sent by the terminal 100 flows into the bluetooth module 203 through the charging interface 202, and is sent to the bluetooth headset 300 through the bluetooth module 203, so that the audio information in the terminal 100 is played in the bluetooth headset 300.

Or, in the communication state, the bluetooth headset charging box 200 is electrically connected to the terminal 100, and the bluetooth headset charging box 200 is bluetooth connected to the bluetooth headset 300.

The second end of the second resistor R2 is connected to the first end of the fourth resistor R4 and the gate of the second fet Q2, respectively. The second end of the fourth resistor R4 and the source of the second field effect transistor Q2 are both grounded. A first terminal of a third resistor R3 is connected to the source of a first FET Q1 and is in communication with node VOUT-5V. A first terminal of a fifth resistor R5 is connected to the drain of the first fet Q1 and the drain of the third fet Q3 and is in communication with the node V-BUS. A second terminal of the fifth resistor R5 is connected to the cathode of the first diode D1. The anode of the first diode is respectively connected with the gate of the third field effect transistor Q3 and the second end of the voltage stabilizing circuit G1. The source of the third fet Q3 is connected to the source of the fourth fet Q4. The drain of the fourth FET Q4 is coupled to a first terminal of a sixth resistor R6 and is in communication with the node VBUS-UART. The gate of the fourth field effect transistor Q4 is respectively communicated with the second end of the sixth resistor R6 and the first end of the voltage stabilizing circuit G1.

For example, the regulated output value of the switching power supply G1 may be 2.5V.

It is understood that the bidirectional communication circuit 207 shown in fig. 4 needs to be connected to the control module 204 and the headset interface 206 to implement the bidirectional communication function between the bluetooth headset charging box 200 and the bluetooth headset 300, and the bluetooth headset charging box 200 can obtain the power information of the bluetooth headset 300.

Illustratively, node V-BUS is coupled to the earphone interface 206, node VOUT-5V, node VBUS-EN, and node VBUS-UART are coupled to the control module 204. Node VOUT-5V is used to provide 5V power for bi-directional communication circuit 207. Node VBUS-EN is used to control the operating state of bi-directional communication circuit 207. The node V-BUS and the node VBUS-UART are used to transmit interactive signals between the bluetooth headset charging box 200 and the bluetooth headset 300. The interactive signal transmitted between the bluetooth headset charging box 200 and the bluetooth headset 300 may be a voltage signal or a current signal, which is not limited in this application.

As a possible implementation manner, the control module 204 may send first information to the bluetooth headset 300, where the first information is used to instruct the bluetooth headset 300 to feed back the power information of the bluetooth headset 300. The control module 204 receives a first response sent by the bluetooth headset 300, where the first response includes power information of the bluetooth headset 300.

Illustratively, the control module 204 sends the first information to the bluetooth headset 300 via the node V-BUS of the bidirectional communication circuit 207, and the bidirectional communication circuit 207 obtains the power information of the bluetooth headset 300 via the node V-BUS and sends the power information of the bluetooth headset 300 to the control module 204 via the node VBUS-UART, so that the control module 204 can obtain the power information of the bluetooth headset 300 via the bidirectional communication circuit 207.

For example, the control module 204 may control the bi-directional communication circuit 207 to enter an enabled state by changing the voltage of the node VBUS-EN. The control module 204 may transmit the voltage change of the node VBUS-UART to the node V-BUS through the third fet Q3 and the fourth fet Q4 by changing the voltage of the node VBUS-UART. After the bluetooth headset 300 obtains the voltage change from the node V-BUS through the headset interface 206, the power information of the bluetooth headset 300 is transmitted by changing the voltage value of the node V-BUS.

Then, the voltage change of the node V-BUS is transmitted to the node VBUS-UART through the third field effect transistor Q3 and the fourth field effect transistor Q4. Thus, the control module 204 may receive a signal of the node VBUS-UART, such as: a voltage value or a current value. In this way, the control module 204 can obtain the power information of the bluetooth headset 300 through the bidirectional communication circuit 207.

The first end of the Hall switch H1 is connected with the node BAT-P, and the third end of the Hall switch H1 is grounded.

It should be noted that the open state or the closed state of the charging chamber can be converted into an electrical signal, such as a voltage signal, by the hall switch H1. The charge bin switch detect circuit 208 shown in fig. 5 can thus transmit the switch state of the charge bin to the control module 204 via an electrical signal.

Illustratively, BAT-P is the positive terminal of the battery 201, and AN2 is connected to the control module 204. Assuming that the charging chamber is changed from the open state to the closed state, the hall switch H1 is actuated, the node AN2 is changed from the low state to the high state, and sends a high signal to the control module 204, so that the control module 204 receives the high signal indicating that the charging chamber is changed from the open state to the closed state.
