Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
At present, a charging box of the wireless earphone and the wireless earphone are in a multi-point contact mode, independent charging contacts and data communication contacts are arranged, and some wireless earphones need sensors to identify whether the wireless earphone is placed in the charging box.
However, the volume of the wireless headset and the volume of the charging box are both small, and a plurality of spaces for the contacts and the sensors are required to be reserved in the small spaces, which undoubtedly increases the design difficulty and the manufacturing cost of the wireless headset and the charging box.
Based on this, the application provides a wireless earphone, box and charging system charge, need not to dispose the sensor and a plurality of contacts that are used for detecting whether wireless earphone gets into the box on wireless earphone or the box that charges, just can realize wireless earphone's resetting, charging, make wireless earphone and the box that charges carry out data communication to make the box that charges obtain wireless earphone's income box testing result.
Specifically, as shown in fig. 1-1, a first structural diagram of a wireless headset according to an embodiment of the present application is provided, where the wireless headset may include: the charging system comprises a first charging port 10, a high-level trigger switch module 11, a charging switch module 12, a reset switch module 13 and a communication switch module 14 which are respectively connected with the first charging port 10, and a first control module 15 connected with the communication switch module.
In the embodiment of the present application, the first charging port 10 is configured to receive a charging voltage, and receive a first data signal and transmit a second data signal.
The first data signal is a data signal sent by the charging box and received after the wireless earphone is placed in the charging box; the second data signal is a data signal sent by the wireless earphone to the charging box through the first charging port. The first data signal and the second data signal are logic level signals of 1.8V-3.3V, and the charging voltage is a voltage signal of 4V-5V.
In the embodiment of the present application, as shown in fig. 1-1, the high-level trigger switch module 11 is connected to the first charging port 10, the charging switch module 12, and the reset switch module 13, and is configured to control the charging switch module 12 and the reset switch module 13 to be in a conducting state when the first charging port 10 receives a charging voltage, so as to charge a battery of the wireless headset, and control the first control module 15 to be in a reset state; when the first charging port 10 does not receive the charging voltage, the charging switch module 12 and the reset switch module 13 are controlled to be in an off state.
In a specific implementation, optionally, as shown in fig. 2, the high-level trigger switch module 11 may include: the voltage source circuit comprises a voltage input end V _ in, a first resistor R1, a second resistor R2, a third resistor R3, a first switch tube T1, a power supply access end VDD, a voltage output end V _ out and a ground end GND.
The voltage input terminal V _ in is commonly connected to the first charging port and the first terminal of the first resistor R1, the second terminal of the first resistor R1, the first terminal of the second resistor R2, and the control terminal of the first switch transistor T1, the second terminal of the second resistor R2, the second terminal of the first switch transistor T1, and the ground terminal, the first terminal of the first switch transistor T1, the first terminal of the third resistor R3, and the voltage output terminal V _ out, and the second terminal of the third resistor R3 is commonly connected to the power supply connection terminal VDD. The power supply access end VDD is used for being connected with a battery of the wireless earphone.
In a specific implementation, the voltage input terminal V _ in is connected to the first charging port, when the first charging port receives a charging voltage, the first switch transistor T1 is turned on by adjusting a ratio of R1 to R2, and at this time, the voltage output terminal V _ out outputs a logic low level to control the charging switch module and the reset switch module to be in a conducting state, to charge the battery of the wireless headset, and to control the first control module to be in a reset state.
When the first charging port does not receive the charging voltage, for example, the first charging port receives the first data signal, or is in a data transmission state, that is, when the wireless headset transmits the second data signal to the charging box through the first charging port, since the logic high levels of the first data signal and the second data signal are 1.8V to 3.3V, the first switching tube T1 cannot be turned on, that is, the first switching tube T1 is in an off state, and the voltage output end V _ out outputs a logic high level, so that the charging switching module and the reset switching module are in the off state, and further the first control module is no longer in a state of being constantly reset, and enters a normal working state.
Optionally, in an embodiment of the present application, as shown in fig. 1-1, the high-level trigger switch module 11 may be further connected to the communication switch 14, and when the first charging port receives the charging voltage, the communication switch module 14 is controlled to be in a turned-off state, so as to protect a chip in the wireless headset from being burned down; and when the first charging port does not receive the charging voltage, controlling the communication switch module 14 to be in a conducting state, so that the wireless earphone and the charging box carry out data communication.
Because the software program of the wireless headset is more and more complex, in practical application, the wireless headset may be in a state that the wireless headset cannot normally work, such as "crash" before being placed in the charging box, and therefore, in the embodiment of the present application, the charging switch module and the reset switch module need to be directly connected with the high-level trigger switch module and are directly controlled by the high-level trigger switch module, so that the forced reset of the wireless headset is realized under the trigger of the high-level trigger switch module, and the wireless headset cannot be indirectly controlled by the control module (the first control module) of the wireless headset.
After the wireless headset is reset, the wireless headset can enter a normal working state again, so that the high-level trigger switch module can indirectly control the state of the communication switch module 14 through the first control module 15, and the communication switch module is controlled without being directly connected with the communication switch module 14.
Specifically, as shown in fig. 1-2, the high-level trigger switch module 11 may be further configured to be connected to the first control module 15, and when the first charging port receives the charging voltage, the first control module 15 controls the communication switch module 14 to be in the off state, and when the first charging port does not receive the charging voltage, the first control module 15 controls the communication switch module to be in the on state.
For example, when the first charging port receives a charging voltage, the first control module is in a reset state, and at this time, the communication switch module can be in a high-impedance state, that is, in a closed state, through the first control module, so as to protect a chip in the wireless headset from being burned out; and when the first charging port does not receive the charging voltage, the first control module can control the communication switch module to be in a conducting state according to a voltage signal output by the high-level trigger switch module, so that the wireless earphone can be converted into a communication mode and normally performs data communication with the charging box.
In some embodiments of the present application, the first control module 15 is connected to the communication switch module 14, and configured to receive the first data signal sent by the charging box and send the second data signal to the charging box when the charging switch module 12 and the reset switch module 13 are in an off state, so that the wireless headset and the charging box perform data communication, and the charging box confirms that the wireless headset is placed in the charging box when receiving the second data signal sent by the wireless headset.
That is, when the charging switch module 12 and the reset switch module 13 are in the off state, the first control module is no longer in the state of being continuously reset, and enters the normal operating state, so that the charging box can perform data communication with the charging box according to the communication requirement, and the charging box can confirm that the wireless headset is placed in the charging box when receiving the data signal sent by the wireless headset.
In the embodiment of the application, the wireless earphone is provided with the first charging port, and the first charging port is connected with the high-level trigger switch module, the charging switch module, the reset switch module and the communication switch module, so that the wireless earphone realizes the integration of a data communication contact and a charging contact, the contacts of the wireless earphone are reduced, and the wireless earphone is also connected with the high-level trigger switch module through the first charging port, the charging switch module and the reset switch module, so that when the first charging port receives charging voltage, the high-level trigger switch module can control the charging switch module and the reset switch module to be in a conducting state, so as to control the first control module to be in a reset state all the time and charge a battery of the wireless earphone; when the first charging port does not receive the charging voltage, (for example, when the first charging port receives a first data signal or the wireless headset sends a second data signal to the charging box through the first charging port), the charging switch module and the reset switch module are controlled to be in an off state; the first control module is further enabled not to be in a state of being continuously reset, but to enter a normal working state, namely, the wireless earphone is enabled to enter a state of carrying out data communication with the charging box, and the charging box is enabled to confirm that the wireless earphone is placed in the charging box when receiving a data signal sent by the wireless earphone; the wireless earphone can be reset and charged without arranging a sensor and a plurality of contacts for detecting whether the wireless earphone is plugged into the box on the wireless earphone or the charging box, so that the wireless earphone and the charging box are in data communication, and the charging box obtains the detection result of the wireless earphone when the wireless earphone is plugged into the box.
Optionally, the communication switch module may include a first communication switch unit and a second communication switch unit. Based on the embodiment shown in fig. 1-2, the first control module may be connected to the first communication switch unit and the second communication switch unit, and configured to control the first communication switch unit to be in an on state and control the second communication switch unit to be in an off state when receiving the first data signal sent by the charging box; and controlling the first communication switch unit to be in an off state and controlling the second communication switch unit to be in an on state when the second data signal is transmitted to the charging box.
Specifically, the first communication switch unit and the second communication switch unit may include a switching tube. For example, as shown in fig. 3, the first and second communication switch units may include seventh and eighth switching tubes T7 and T8.
The first control module is connected to the seventh switch transistor T7 and the eighth switch transistor T8, and configured to control the seventh switch transistor T7 to be in an on state and control the eighth switch transistor T8 to be in an off state when receiving the first data signal sent by the charging box; and when the second data signal is sent to the charging box, controlling the seventh switching tube T7 to be in an off state, and controlling the eighth switching tube T8 to be in an on state.
