In some embodiments, the first switch comprises a first MOS transistor, the second switch comprises a second MOS transistor, and the third switch comprises a third MOS transistor. It will be appreciated that the first, second and third switches may also be other types of switches, such as relays, etc.
Fig. 2 is a schematic circuit diagram of a wireless headset reset circuit according to an embodiment of the present invention. The TX/RX is a signal transmitting/receiving end, the signal transmitting/receiving end TX/RX is connected with the first MOS tube Q1 through a communication line, and the first resistor R1 is a pull-up resistor of the communication line. Bt_reset is a RESET signal output terminal connected to the wireless communication chip 300.
The detection circuit 100 includes a first MOS transistor Q1, a second MOS transistor Q2, a third resistor R3, and a first capacitor C1, and the reset circuit 200 includes a second resistor R2 and a third MOS transistor Q3. The grid of first MOS pipe Q1 is connected with the communication line respectively, the grid of second MOS pipe Q2, the source electrode of first MOS pipe Q1 connects power input VCC, the drain electrode of first MOS pipe Q1 is connected with the drain electrode of second MOS pipe Q2 respectively through third resistance R3, the one end of first electric capacity C1, the source electrode ground connection of second MOS pipe Q2, the other end ground connection of first electric capacity C1, the one end of first electric capacity C1 is connected with the grid of third MOS pipe Q3, the drain electrode of third MOS pipe Q3 is connected with power input VCC through second resistance R2, the drain electrode of third MOS pipe Q3 still is connected with wireless communication chip 300 through RESET signal output BT_RESET, the source electrode ground connection of third MOS pipe Q3. The grounding means that the grounding wire is connected with the ground wire of the wireless earphone.
As shown in fig. 2, the communication line and the ground line are connected through a switch S1. Referring to the above, when the wireless earphone is not put into the earphone box, the switch S1 may be a wire, through which the communication line contact and the ground line contact are shorted, so that the communication line and the ground line may be connected; when the wireless earphone is placed in the earphone box, the switch S1 can be a MOS switch tube or a relay or other types of switches, and when the wireless earphone is placed in the earphone box, the earphone box sends out a signal to control the switch S1 to be conducted, so that connection between a communication line and a ground line of the wireless earphone can be realized.
The specific principle is as follows:
When the communication line of the wireless earphone is connected with the ground line, the switch S1 is turned on, and the voltage of the communication line is 0V. The voltage difference between the gate voltage and the source voltage of the first MOS transistor Q1 is the voltage value of the power input end VCC, the first MOS transistor Q1 is conducted, the first capacitor C1 is charged through the third resistor R3, the voltage difference between the gate voltage and the source voltage of the second MOS transistor Q2 is 0V, and the second MOS transistor Q2 is cut off. When the voltage on the first capacitor C1 rises to the on voltage of the third MOS transistor Q3, the third MOS transistor Q3 is turned on, the RESET signal output terminal bt_reset is at a low level, and the wireless communication chip 300 is RESET.
When the communication wire and the ground wire of the wireless earphone are not connected or the wireless earphone is not in communication, the voltage of the communication wire is kept at a high level. The voltage difference between the gate voltage and the source voltage of the first MOS transistor Q1 is 0V, and the first MOS transistor Q1 is cut off. The voltage difference between the gate voltage and the source voltage of the second MOS transistor Q2 is the voltage value of the power input end VCC, the second MOS transistor Q2 is conducted, the gate voltage of the third MOS transistor Q3 is pulled to the ground, the voltage difference between the gate voltage and the source voltage of the third MOS transistor Q3 is 0V, and the third MOS transistor Q3 is cut off. The RESET signal output terminal bt_reset is high level, and the wireless communication chip 300 is not RESET.
When the wireless earphone and the earphone box are in communication, the voltage of the communication line is in an alternating state of 0V and high level, and the grid voltages of the first MOS tube Q1 and the second MOS tube Q2 are also in alternating state. However, due to the charging delay factors of the third resistor R3 and the first capacitor C1, the voltage of the first capacitor C1 rises slowly, and discharges quickly through the second MOS transistor Q2, so that the voltage on the first capacitor C1 cannot reach the on voltage of the third MOS transistor Q3, the third MOS transistor Q3 is turned off, the RESET signal output terminal bt_reset keeps high level, the wireless communication chip 300 is not RESET, and the normal use of the wireless earphone is prevented from being affected due to the RESET when the wireless communication is performed.
In this embodiment, the wireless communication chip 300 is a bluetooth chip, and may be other chips capable of implementing wireless communication, such as an NFC chip, to implement a wireless communication function of the wireless headset.
Further, the embodiment also provides a wireless earphone, which comprises a power module and the wireless earphone reset circuit in any embodiment. The power supply module is respectively connected with the detection circuit 100, the reset circuit 200 and the wireless communication chip 300, and supplies power to the detection circuit 100, the reset circuit 200 and the wireless communication chip 300 through a power supply input end VCC.
In this embodiment, the wireless communication chip 300 is a bluetooth chip, and correspondingly, the wireless earphone is a bluetooth earphone.

S1, detecting whether a communication line is connected with a ground line, and if so, executing the step S2; otherwise, the flow ends;

The specific process of the reset method is referred to the above description of the reset circuit, and will not be repeated here.
