Referring to fig. 1, fig. 1 is a schematic diagram of a wireless earphone provided by an embodiment of the present invention, where the wireless earphone includes a wireless communication unit 110 and a charging interface 120, where the wireless communication unit 110 is configured to establish wireless connection with an external device (such as a smart device such as a mobile phone, a tablet computer, etc.) to obtain audio data, and for example, the wireless communication unit may be a bluetooth communication unit, and the charging interface 120 is configured to be electrically connected to a charging circuit of a charging bin when the wireless earphone is located in the charging bin, so as to obtain power from the charging bin, and the wireless earphone further includes a detection processing unit 130 and a control unit 140;
The detection processing unit 130 is connected to the charging interface 120 and the control unit 240, where the detection processing unit 130 is configured to detect a voltage of the charging interface 120, time a duration of the charging interface 120 in a preset voltage state, and send a binning instruction to the control unit 140 when the time of the time reaches a current binning instruction trigger duration, where the preset voltage state is a state in which the voltage of the charging interface 120 is greater than a threshold value;
Namely, when the wireless earphone is in an out-of-bin state (namely, the wireless earphone is positioned outside the charging bin), the voltage of the charging interface of the wireless earphone is in a state smaller than the threshold value, when the detection processing unit detects that the voltage of the charging interface is changed from the state smaller than the threshold value to the state larger than the threshold value, the timing is started, and then, when the voltage of the charging interface is changed from the state larger than the threshold value to the state smaller than the threshold value, the timing is ended;
The detection processing unit 130 may implement timing by using a clock counter.
The control unit 140 is connected to the wireless communication unit 110, and the control unit 240 is configured to close the wireless communication unit 110 when receiving the binning instruction, that is, control the wireless earphone to enter a low power consumption mode;
The detection processing unit 130 is further configured to determine the timing result, and adjust the trigger duration of the warehousing instruction when the timing result is in a preset range.
The timing result is a time length from starting timing to ending timing.
According to the wireless earphone provided by the embodiment of the invention, the voltage of the self-charging interface is detected, the duration time of the self-charging interface in the preset voltage state is counted, the self-charging interface is judged to be changed from the discharging state to the charging state when the counted time reaches the charging instruction triggering time, and the charging instruction triggering time can be adjusted in real time according to the counted result, so that more accurate charging detection can be realized, and lower power consumption can be realized.
The wireless earphone in the embodiment of the invention can be a left earphone or a right earphone in the TWS earphone.
For example, in an embodiment, the detection processing unit 130 and the control unit 140 are integrated in the same chip in the wireless headset, which may be the processing chip of the wireless headset;
For example, in an embodiment, a corresponding analog circuit and/or digital circuit may be added to the processing chip of the existing wireless earphone, that is, the detection processing unit 130 is implemented by a hardware circuit, so that the performance of the earphone is prevented from being affected by implementing the above-mentioned in-bin detection, which is beneficial to reducing the operation load of the CPU, and normal detection and adjustment may be implemented in the chip sleep state.
For example, in one embodiment, referring to fig. 2, the detection processing unit includes a voltage detection unit 131 and a signal processing unit 132;
The voltage detection unit 131 is connected to the charging interface 120, where the voltage detection unit 131 is configured to detect a voltage of the charging interface 120, and output a preset signal to the signal processing unit 132 when the charging interface 120 is in the preset voltage state, for example, the voltage detection unit 131 may be implemented by an analog circuit, and the preset signal may be, for example, a low level signal or a high level signal;
For example, a high level signal is output to the signal processing unit 132 when the charging interface 120 is in the preset voltage state, a low level signal is output to the signal processing unit 132 when it is not in the preset voltage state (when the voltage of the charging interface is less than the above-mentioned threshold value), or a low level signal is output to the signal processing unit 132 when the charging interface 120 is in the preset voltage state, a high level signal is output to the signal processing unit 132 when it is not in the preset voltage state (when the voltage of the charging interface is less than the above-mentioned threshold value);
The signal processing unit 132 is connected to the voltage detecting unit, and is configured to detect the preset signal and time the duration of the preset signal, and may be implemented by a digital circuit, for example.
Specifically, the signal processing unit starts timing when detecting that the voltage detection unit starts outputting the preset signal, and finishes timing when the voltage detection unit stops outputting the preset signal, if the timing time can reach the current trigger duration of the warehousing instruction, the signal processing unit sends the warehousing instruction to the control unit when reaching the current trigger duration of the warehousing instruction, so that the wireless communication unit is closed, and the wireless earphone is controlled to enter a low-power consumption mode.
In the embodiment of the invention, when the wireless earphone is located in the charging bin, the charging bin applies a preset voltage to the charging interface of the earphone to supply power to the wireless earphone, so that the voltage of the charging interface of the earphone can be detected to be larger than the threshold value, and when the earphone is not located in the charging bin, the voltage of the charging interface of the earphone is detected to be smaller than the threshold value because the charging bin does not apply the voltage to the charging interface of the earphone, so that the in-bin state and the out-of-bin state of the earphone can be judged, wherein the magnitude of the threshold value can be set according to the preset voltage applied to the charging interface of the earphone by the charging bin.
In the embodiment of the invention, an initial trigger time length of the warehousing instruction can be preset in the wireless earphone, in a subsequent process, whether the current trigger time length of the warehousing instruction is accurate or not can be judged through a timing result, and real-time adjustment is performed on the current trigger time length of the warehousing instruction, namely when the timing result is smaller than the current trigger time length of the warehousing instruction and the difference value of the current trigger time length and the current trigger time length is larger, the current burr signal (interference signal such as a signal generated by static electricity, poor contact of a charging contact and the like) is smaller in width (the time length is smaller), so that the trigger time length of the warehousing instruction can be correspondingly reduced, the state of entering and exiting the warehousing can be recognized earlier, and the wireless earphone enters a low-power consumption mode as early as possible, and the energy consumption is reduced;
When the counted time reaches the current trigger time of the warehousing instruction, the detection processing unit sends the warehousing instruction and continues counting so as to judge whether a burr signal with larger width (longer time) exists currently. Preferably, a larger preset time period tin_max may be preset, if the counted time reaches the preset time period tin_max, the charging interface is still in the preset voltage state (the state that the voltage of the charging interface is greater than the threshold value), then the current burr signal with larger width (longer time) may not exist, the detection processing unit finishes counting, and determines that the current trigger time period of the warehousing instruction does not need to be adjusted, if the counted time period reaches the preset time period tin_max, the charging interface is changed from the state that the charging interface is in the preset voltage state to the state that the charging interface is not in the preset voltage state (the state that the voltage of the charging interface is less than the threshold value), then the current burr signal with larger width (longer time) may be judged, therefore, the trigger time period of the warehousing instruction may be correspondingly increased, so as to improve the accuracy of the warehousing detection.
The specific size of tin_max can be set according to specific situations.
For example, in one embodiment, the detection processing unit 130 is configured with:
If the timing result is smaller than K1-tin_set (i.e. the charging interface is changed from being in the preset voltage state to not being in the preset voltage state before the time of K1-tin_set), the trigger duration of the binning instruction is reduced;
and/or if the timing result is greater than tin_set and less than tin_max, increasing the trigger time length of the warehousing instruction;
Wherein, K1 is a preset factor greater than 0 and less than 1, tin_set is a current trigger duration of the in-store instruction, tin_max is a preset duration, and tin_max is greater than tin_set, for example, the value of K1 is any value from 0.3 to 0.8, for example, the value of K1 is 0.5.
For example, in an embodiment, the detection processing unit is configured with: if the result of the timing is smaller than k1×tin_set, the trigger duration of the binning instruction is reduced by:
And/or if the result of the timing is greater than tin_set and less than tin_max, increasing the binning instruction trigger time by:
wherein tin_set' is the adjusted trigger duration of the warehousing instruction, tin_set is the current trigger duration of the warehousing instruction, and Tin is the timing result.
For example, in one embodiment, referring to fig. 3, the wireless headset binning control process is as follows:
When the wireless earphone is in the out-of-bin state, the wireless communication unit 110 is in an on state, and when the detection processing unit 130 detects that the voltage of the charging interface 120 changes from a state smaller than a threshold value to a state larger than the threshold value, specifically, when the voltage detection unit 131 starts to output a preset signal, the signal processing unit 132 starts a clock counter;
If the timing result is smaller than K1 x tin_set, the detection processing unit 130 decreases the trigger time period tin_set of the binning instruction according to the above-mentioned preset rule, specifically, in this case, the signal processing unit 132 may decrease tin_set according to the preset rule, clear the preset signal (filtering process) output by the voltage detecting unit 131, and turn off the clock counter;
if the result of the timing is greater than K1 x tin_set and less than tin_set, determining that the signal is currently a glitch signal, and not currently sending a binning instruction and not adjusting the trigger time period tin_set of the binning instruction, specifically, in this case, the signal processing unit 132 may clear the preset signal (filtering process) output by the voltage detecting unit 131, and turn off the clock counter;
if the counted time can reach the current time period tin_set of triggering the binning instruction, when the counted time reaches the current time period tin_set of triggering the binning instruction, the detection processing unit 130 sends the binning instruction to the control unit 140, so that the wireless communication unit 110 is closed, and the wireless earphone enters a low-power mode, specifically, in this case, the signal processing unit 132 can send the binning instruction to the control unit 140;
Then, if the result Tin of the timing is greater than tin_set and less than tin_max, it indicates that there is a burr signal with a larger width, and the detection processing unit 130 increases the trigger time period tin_set of the binning instruction according to the above-mentioned preset rule, specifically, in this case, the signal processing unit 132 may turn off the clock counter and increase the trigger time period tin_set of the binning instruction according to the preset rule;
when the counted time can reach tin_max, it may be determined that there is no burr signal having a large width (longer time), the detection processing unit 130 may end the counting, and determine that there is no need to adjust the trigger time of the binning instruction, specifically, in this case, the clock counter may be turned off by the signal processing unit 132.
Through the mode, interference to the warehousing detection of the Bluetooth headset caused by static electricity, poor contact of the charging contact and the like can be reduced, and the adaptability to the individual differences of different TWS Bluetooth headsets is high.
Referring to fig. 4, fig. 4 is a schematic diagram of a wireless earphone provided by an embodiment of the present invention, where the wireless earphone includes a wireless communication unit 210 and a charging interface 220, where the wireless communication unit 210 is configured to establish wireless connection with an external device (such as a smart device of a mobile phone, a tablet computer, etc.) to obtain audio data, and the wireless communication unit may be, for example, a bluetooth communication unit, and the charging interface 220 is configured to be electrically connected to a charging circuit of a charging bin when the wireless earphone is located in the charging bin, so as to obtain power from the charging bin, and the wireless earphone further includes a detection processing unit 230 and a control unit 240;
The detection processing unit 230 is connected to the charging interface 220 and the control unit 240, where the detection processing unit 230 is configured to detect a voltage of the charging interface 220, time a duration of the charging interface 220 in a preset voltage state, and send an out-of-bin instruction to the control unit 240 when the time of the time reaches a current out-of-bin instruction trigger duration, where the preset voltage state is a state in which the voltage of the charging interface 220 is less than a threshold;
Namely, when the wireless earphone is in a warehousing state (namely, the wireless earphone is positioned in a charging warehouse), the voltage of a charging interface of the wireless earphone is in a state larger than the threshold value, when the detection processing unit detects that the voltage of the charging interface is changed from the state larger than the threshold value to the state smaller than the threshold value, the timing is started, and then, when the voltage of the charging interface is changed from the state smaller than the threshold value to the state larger than the threshold value, the timing is ended;
the detection processing unit 230 may implement timing by using a clock counter.
The control unit 240 is connected to the wireless communication unit 210, and the control unit 240 is configured to, when receiving the unloading instruction, turn on the wireless communication unit 210, so that the wireless headset can establish wireless connection with an external device (such as a smart device such as a mobile phone, a tablet computer, etc.), for example, establish wireless connection in a back connection manner;
The detection processing unit 230 is further configured to determine the timing result, and adjust the trigger duration of the discharging instruction when the timing result is within a preset range.
The timing result is a time length from starting timing to ending timing.
According to the wireless earphone provided by the embodiment of the invention, the voltage of the self-charging interface is detected, the duration time of the self-charging interface in the preset voltage state is counted, the self-charging state is judged to be changed into the discharging state when the counted time reaches the discharging instruction triggering time, and the discharging instruction triggering time can be adjusted in real time according to the counted result, so that more accurate discharging detection can be realized, and lower power consumption can be realized.
The wireless earphone in the embodiment of the invention can be a left earphone or a right earphone in the TWS earphone.
For example, in an embodiment, the detection processing unit 230 and the control unit 240 are integrated in the same chip in the wireless headset, which may be the processing chip of the wireless headset.
For example, in an embodiment, a corresponding analog circuit and/or digital circuit may be added to the processing chip of the existing wireless earphone, that is, the detection processing unit 230 is implemented by a hardware circuit, so that the influence of the implementation of the above-mentioned out-of-bin detection on the performance of the earphone can be avoided, which is beneficial to reducing the operation load of the CPU, and normal detection and adjustment can be implemented in the chip sleep state.
For example, in one embodiment, referring to fig. 5, the detection processing unit includes a voltage detection unit 231 and a signal processing unit 232;
The voltage detection unit 231 is connected to the charging interface 220, and the voltage detection unit 231 is configured to detect a voltage of the charging interface 220, and output a preset signal to the signal processing unit 232 when the charging interface 220 is in the preset voltage state, for example, the voltage detection unit 231 may be implemented by an analog circuit, and the preset signal may be, for example, a low level signal or a high level signal;
for example, a high level signal is output to the signal processing unit 132 when the charging interface 220 is in the preset voltage state, a low level signal is output to the signal processing unit 232 when it is not in the preset voltage state (when the voltage of the charging interface is greater than the above-mentioned threshold value), or a low level signal is output to the signal processing unit 232 when the charging interface 220 is in the preset voltage state, a high level signal is output to the signal processing unit 232 when it is not in the preset voltage state (when the voltage of the charging interface is greater than the above-mentioned threshold value);
The signal processing unit 232 is connected to the voltage detecting unit, and the signal processing unit 232 is configured to detect the preset signal and time the duration of the preset signal, for example, the signal processing unit may be implemented by using a digital circuit.
Specifically, the signal processing unit starts timing when detecting that the voltage detection unit starts outputting the preset signal, and finishes timing when the voltage detection unit stops outputting the preset signal, if the timing time can reach the current trigger duration of the discharging instruction, the signal processing unit sends the discharging instruction to the control unit when reaching the current trigger duration of the discharging instruction, so that the wireless communication unit is started.
In the embodiment of the invention, when the wireless earphone is located in the charging bin, the charging bin applies a preset voltage to the charging interface of the earphone to supply power to the wireless earphone, so that the voltage of the charging interface of the earphone can be detected to be larger than the threshold value, and when the earphone is not located in the charging bin, the voltage of the charging interface of the earphone is detected to be smaller than the threshold value because the charging bin does not apply the voltage to the charging interface of the earphone, so that the in-bin state and the out-of-bin state of the earphone can be judged, wherein the magnitude of the threshold value can be set according to the preset voltage applied to the charging interface of the earphone by the charging bin.
In the embodiment of the invention, an initial trigger time length of the delivery instruction can be preset in the wireless earphone, in a subsequent process, whether the current trigger time length of the delivery instruction is accurate or not can be judged through a timing result, and real-time adjustment is performed on the current trigger time length of the delivery instruction, namely when the timing result is smaller than the current trigger time length of the delivery instruction and the difference value between the current trigger time length and the current trigger time length is larger, the current burr signal (interference signal such as a signal generated by static electricity, poor contact of a charging contact and the like) is smaller in width (the time length is smaller), so that the trigger time length of the delivery instruction can be correspondingly reduced, the delivery state can be recognized earlier, and the wireless earphone can be quickly connected with external equipment in a wireless way;
When the counted time reaches the current trigger time of the discharging instruction, the detecting and processing unit sends the discharging instruction and continues counting so as to judge whether a burr signal with larger width (longer time) exists at present. Preferably, a larger preset duration tout_max may be preset, if the counted time reaches the preset duration tout_max, the charging interface is still in the preset voltage state (the state that the voltage of the charging interface is smaller than the threshold value), then it may be judged that there is no burr signal with a larger width (longer time), the detection processing unit may end the counting, and determine that there is no need to adjust the trigger duration of the discharging instruction currently, if the counted time reaches the preset duration tout_max, the charging interface is changed from the state that is in the preset voltage state to the state that is not in the preset voltage state (the state that the voltage of the charging interface is greater than the threshold value), then it may be judged that there is a burr signal with a larger width (longer time) currently, so the trigger duration of the discharging instruction may be correspondingly increased, so as to improve the accuracy of the discharging detection.
The specific size of tout_max may be set according to the specific situation.
For example, in one embodiment, the detection processing unit 230 is configured with:
if the timing result is smaller than K2 Tout_set, reducing the trigger duration of the discharging instruction;
and/or if the result of the timing is greater than tout_set and less than tout_max, increasing the trigger time of the out-of-bin instruction;
Wherein K2 is a preset factor greater than 0 and less than 1, tout_set is a current trigger duration of the out-of-bin instruction, tout_max is a preset duration, and tout_max is greater than tout_set, for example, the value of K2 is any value from 0.3 to 0.8, for example, the value of K2 is 0.5.
For example, in one embodiment, the detection processing unit 230 is configured with: if the result of the timing is less than k2×tout_set, the trigger duration of the out-of-bin instruction is reduced by:
and/or if the result of the timing is greater than tout_set and less than tout_max, increasing the pop instruction trigger duration by:
Wherein tout_set' is the adjusted trigger duration of the out-of-bin instruction, tout_set is the current trigger duration of the out-of-bin instruction, and Tout is the result of the timing.
For example, in one embodiment, referring to fig. 6, the wireless headset's ex-bin control process is as follows:
When the wireless earphone is in the in-store state, the wireless communication unit 210 is in the off state, and when the detection processing unit 230 detects that the voltage of the charging interface 220 changes from a state greater than a threshold value to a state less than the threshold value, specifically, when the voltage detection unit 231 starts to output a preset signal, the signal processing unit 232 starts a clock counter;
if the result of the timing is smaller than k2×tout_set, the detection processing unit 230 decreases the trigger duration tout_set of the discharging instruction according to the above-mentioned preset rule, in which case, the signal processing unit 232 may decrease tout_set according to the preset rule, clear the preset signal (filtering process) output by the voltage detecting unit 231, and turn off the clock counter;
If the result of the timing is greater than k2×tout_set and less than tout_set, determining that the signal is currently a glitch signal, and there is no need to send the out-of-bin instruction and no need to adjust the out-of-bin instruction trigger duration tout_set, specifically, in this case, the signal processing unit 232 may clear the preset signal (filtering process) output by the voltage detecting unit 231, and turn off the clock counter;
If the counted time can reach the current trigger duration tout_set of the in-bin instruction, when the counted time reaches the current trigger duration tout_set of the out-bin instruction, the detection processing unit 230 sends the out-bin instruction to the control unit 240, so as to turn on the wireless communication unit 210, in which case the out-bin instruction may be sent by the signal processing unit 232 to the control unit 240;
Then, if the result Tout of the timing is greater than tout_set and less than tout_max, it indicates that there is a burr signal with a larger width, and the detection processing unit 230 increases the trigger time period tout_set of the discharging instruction according to the above-mentioned preset rule, specifically, in this case, the signal processing unit 232 may turn off the clock counter and increase the trigger time period tout_set of the entering instruction according to the preset rule;
When the counted time can reach tout_max, it may be determined that there is no burr signal having a large width (longer time), and the detection processing unit 230 may end the counting and determine that there is no need to adjust the trigger time of the discharging instruction, specifically, in this case, the clock counter may be turned off by the signal processing unit 232.
