The first input port IO1 of the first bluetooth chip BT1 is a power-on control port a1, and when the input voltage of the power-on control port a1 becomes high, the first bluetooth chip BT1 performs a power-on operation; when the input voltage of the power-on control port A1 becomes low, the first Bluetooth chip BT1 performs a power-off operation. A second input port IO2 of the first bluetooth chip BT1 is a switching command control port B1, and when the input voltage of the switching command control port B1 becomes high, the first bluetooth chip BT1 sends a first bluetooth connection switching command to the smart terminal as a master device through the radio frequency antenna; it should be noted that the first bluetooth connection switching command conforms to a communication protocol agreed in advance by the bluetooth speaker and the intelligent terminal, and after receiving the first bluetooth switching command, the intelligent terminal disconnects the bluetooth connection with the bluetooth speaker and tries to establish the bluetooth connection with the bluetooth headset.
The charging circuit includes: a third power source VCC3, a charge management chip U1, and a first charge terminal J1. The fourth input port of the charge management chip U1 is an enable terminal EN of the charging circuit, and when the input voltage of the enable terminal EN becomes high, the charge management chip U1 outputs a charging voltage of a specified value to the first charging terminal J1; when the input voltage of the enable terminal EN becomes low, the charge management chip U1 stops outputting the charging voltage of the specified value to the first charging terminal JI; further, this charging circuit still includes: decoupling filter capacitors C2, C3 and C4, current limiting resistors R4, R5 and R6, an anti-static diode D4 and a Schottky diode D5 for preventing current from flowing backwards.
The first inverting circuit includes: the second power supply VCC2, current-limiting circuit R3 and MOS transistor Q1, the second power supply VCC2 is connected with one end of a current-limiting resistor R3, and the other end of the current-limiting resistor R3 is connected with the drain of MOS transistor Q1. The source of the MOS transistor is grounded, the gate of the MOS transistor Q1 is the input terminal of the inverter circuit, the drain of the MOS transistor Q1 is the output terminal of the inverter circuit, and when a high voltage is input, the inverter circuit outputs a high voltage, and when a low voltage is input, the inverter circuit outputs a high voltage. Further, the inverter circuit further includes: a voltage-dividing resistor R2, a decoupling filter capacitor C1, a bidirectional voltage stabilizing diode D2 and a diode D3 for preventing current from flowing backwards.
Based on the above characteristics of each part, the connection mode of the circuit used for switching the bluetooth connection inside the bluetooth speaker is as follows: one end of the detection key SW1 is connected with a first power supply VCC1, the other end of the detection key SW1 is respectively connected with a starting control port A1 of the first Bluetooth chip BT1, an enabling end EN of the charging circuit and the input end of a first reverse circuit, and the output end of the first reverse circuit is connected with a switching command control port of the first Bluetooth chip BT 1; further, the circuit also includes: and a current limiting resistor R1 connected in series between the first power source VCC1 and one end of the detection key SW 1.
Correspondingly, the partial circuit for performing bluetooth connection switching inside the bluetooth headset of this embodiment includes: a second bluetooth chip BT2, a second charging terminal J2, and a second inverter circuit. Like the first bluetooth chip BT1, the power-on control port of the second bluetooth chip BT2 is used for performing power-on or power-off operations; the switching command control port of the second Bluetooth sound box BT2 is used for sending a second Bluetooth switching command to the intelligent terminal serving as the main device, the second Bluetooth connection switching command conforms to a communication protocol agreed by the Bluetooth headset and the intelligent terminal in advance, and after receiving the second Bluetooth switching command, the intelligent terminal can disconnect the Bluetooth connection with the Bluetooth headset and try to establish Bluetooth connection with the Bluetooth sound box; the working principle of the second inverter circuit is the same as that of the first inverter circuit, and is not described in detail herein.
Based on the characteristics of each part, the connection mode of the circuit used for switching the Bluetooth connection inside the Bluetooth headset is as follows: the positive electrode of the second charging terminal J2 is connected to the switching command control port of the second bluetooth chip BT2, and the positive electrode of the second charging terminal J2 is connected to the power-on control port of the second bluetooth chip BT2 through a second reverse circuit.
In this embodiment, the working principle of the switching scheme of the uninterrupted bluetooth connection provided by the present invention is as follows:
when the Bluetooth headset is inserted into a charging base of the Bluetooth sound box, a detection key SW1 of the Bluetooth sound box is closed, the input voltage of a power-on control port A1 of a first Bluetooth chip BT1 is increased, the first Bluetooth chip BT1 executes power-on operation, and the Bluetooth sound box is started; and the input voltage of the enable terminal EN of the charging circuit becomes high, outputting the charging voltage of a specified value to the first charging terminal JI.
Meanwhile, since the bluetooth headset is in the charging cradle of the bluetooth speaker and the second charging terminal J2 of the bluetooth headset is in contact with the first charging terminal JI of the bluetooth speaker, the second charging terminal J2 receives a charging voltage of a designated value, the input voltage of the switch command control port of the second bluetooth chip BT2 becomes high, and the second bluetooth chip BT2 transmits a second bluetooth switch command to the smart terminal; and the input voltage of the power-on control port of the second bluetooth chip BT2 becomes low, the second bluetooth chip BT2 performs a power-off operation, and the bluetooth headset is turned off.
After receiving the second Bluetooth switching command, the intelligent terminal disconnects the Bluetooth connection with the Bluetooth earphone and establishes Bluetooth connection with the Bluetooth sound box, so that the Bluetooth connection equipment is switched from the Bluetooth earphone to the Bluetooth sound box.
When the Bluetooth headset is pulled out of the charging base of the Bluetooth sound box, the detection key SW1 of the Bluetooth sound box is disconnected, the input voltage of the switching command control port B1 of the first Bluetooth chip BT1 is increased, and the first Bluetooth chip BT1 sends a first Bluetooth switching command to the intelligent terminal; the input voltage of the power-on control port A1 of the first Bluetooth chip BT1 becomes low, the first Bluetooth chip BT1 executes the power-off operation, and the Bluetooth sound box is closed; and the input voltage of the enable terminal EN of the charging circuit becomes low, the output of the charging voltage of the specified value to the first charging terminal JI is stopped.
Meanwhile, since the bluetooth headset is pulled out from the charging base of the bluetooth speaker and the second charging terminal J2 of the bluetooth headset is separated from the first charging terminal JI of the bluetooth speaker, the second charging terminal J2 no longer receives a charging voltage of a designated value, the input voltage of the power-on control port of the second bluetooth chip BT2 becomes high, and the second bluetooth chip BT2 performs a power-on operation to start the bluetooth headset.
After receiving the first Bluetooth switching command, the intelligent terminal disconnects the Bluetooth connection with the Bluetooth sound box and establishes Bluetooth connection with the Bluetooth headset, so that the Bluetooth connection equipment is switched from the Bluetooth sound box to the Bluetooth headset.

The embodiment describes the process of switching the bluetooth connection of the intelligent terminal between the bluetooth headset and the bluetooth speaker without interrupting the bluetooth connection. For example, a user opens a music player on a mobile phone serving as a main device, and listens to music by using a bluetooth headset connected with bluetooth of the mobile phone, when the bluetooth headset is exhausted, the user inserts the bluetooth headset into a charging base of a bluetooth sound box, that is, the bluetooth connection device of the mobile phone is switched to the bluetooth sound box, and the user listens to the music by using the bluetooth sound box while charging the bluetooth headset; when the user does not want to continue to play the music publicly, the user pulls out the Bluetooth headset from the charging base of the Bluetooth sound box, namely, the Bluetooth connecting equipment of the mobile phone is switched to the Bluetooth headset again, and the user listens to the music by using the Bluetooth headset.
