Referring to
operation S10, in responding to that a first electrical contact is in a charging state, and an earphone box detects that a communication requirement exists between the earphone box and an earphone, adjusting a voltage level of the first electrical contact to send preset signals to the earphone through the first electrical contact.
In this embodiment, the executive terminal is the earphone box.
The TWS earphone is also called TWS Bluetooth® earphone, the TWS earphone does not need wired connection, and the left and right earphone modules form a stereo system through Bluetooth® technology, a song enjoying effect, a talking effect and a wearing effect are improved. Due to the fact that the TWS earphone has a small battery capacity and a short standby time, the TWS earphone is generally used in cooperation with a charging box. When the TWS earphone is not in use, the TWS earphone can be placed in the charging box for charging. The charging box can display the power level of the TWS earphone, such as full power, normal power and low power. The charging box can communicate with the earphone to realize the forced pairing with the TWS earphone, opening or closing the box, over-the-air (OTA) upgrading and the like.
Optionally, the earphone box can adjust the voltage level of the first electrical contact to control the first electrical contact to switch between the charging state and a communication state.
Optionally, when the voltage level of the first electrical contact is adjusted to be +5V, the first electrical contact is in the charging state; and when the voltage level of the first electrical contact is adjusted to be +3.3V, the first electrical contact is in the communication state.
Optionally, the earphone box can detect whether a communication requirement exists between the earphone box and the earphone in real time or regularly. Optionally, when the earphone box detects that there are data needed to be sent to the earphone, the earphone box determines that there is a communication requirement, otherwise, the earphone box determines that there is no communication requirement.
Optionally, upon detecting that there is no communication requirement between the earphone box and the earphone, the earphone box switches the first electrical contact to the charging state; and upon detecting that a communication requirement exists between the earphone box and the earphone, the earphone box switches the first electrical contact to the communication state.
Optionally, when the first electrical contact is in the charging state, the first electrical contact can be used for charging the earphone which is placed in the earphone box and electrically connected with the earphone box. At this time, upon detecting that a communication requirement exists at current, the earphone box can firstly send the preset signals to the earphone through the first electrical contact, to notify the earphone that the earphone box needs to establish a communication with the earphone at current and needs to suspend the charging.
It should be noted that for the earphone in communication with the earphone box, it's second electrical contact needs to electrically connect with the first electrical contact of the earphone box, and it's second ground contact needs to electrically connect with the first ground contact of the earphone box.
Optionally, the earphone box can alternately switch the voltage level of the first electrical contact between the low level (e.g., 0V) and the high level (e.g., 5V) for the first preset number of times, so as to send the preset signals to the earphone. Each time a switching operation of switching between the high level and the low level is performed, it is equivalent to generating one preset signal.
Further, in the process of switching the voltage level of the first electrical contact between the low level and the high level, the earphone box controls the time interval between two adjacent switching operations to be a preset interval.
It should be noted that the preset number of times and the preset interval may be set by an engineer in advance according to the actual condition, for example, the first preset number of times may optionally be 5, and the preset interval may optionally be 4 ms.
As shown in
Operation S20, upon receiving a response signal fed back by the earphone based on the preset signals, switching the first electrical contact to the communication state.
Optionally, after the earphone detects the preset signals formed by the earphone box via the first electrical contact, the number of the detected preset signals can be identified (equivalent to that the total number of the rising edge signals and the falling edge signals of the pulse waveform signals). Upon detecting that the number of the detected preset signals is greater than or equal to the first preset number of times, the earphone switches the second electrical contact from the charging state to the communication state to stop charging, switches the transceiving state of the second electrical contact in the communication state to the TX signaling state, and transmits the response signal obtained by responding based on the preset signals to the earphone box through the second electrical contact.
Optionally, in order to prevent the earphone from missing the preset signals, the number of the preset signals sent by the earphone box may be greater than the preset number of times. For example, when the preset interval is 4 ins and the preset number of times is 5, the pulse waveform signal, the whole period of which is 20 ms, is generated, but in order to prevent the earphone from missing the preset signals, the earphone box can correspondingly generate a pulse waveform signal with the whole period of 40 ins, so that the sum of the rising edges and the falling edges corresponding to the pulse waveform signal can exceed 5.
Optionally; when the earphone box receives a response signal fed back by the earphone based on the preset signals, the first electrical contact is switched from the charging state to the communication state (i.e., the voltage level of the first electrical contact is adjusted to 3.3 V), so as to establish a communication between the earphone box and the earphone.
It should be noted that when the transceiving state of the first electrical contact of the earphone box is the TX signaling state, the earphone box can be used for sending data to the earphone, and when the transceiving state of the first electrical contact of the earphone box is the RX receiving state, the earphone box can be used for receiving the data sent from the earphone. Similarly, when the transceiving state of the second electrical contact of the earphone is the TX signaling state, the earphone can be used for sending data to the earphone box; and when the transceiving state of the second electrical contact of the earphone is the RX receiving state; the earphone can be used for receiving the data sent from the earphone box
Optionally, after the communication between the earphone box and the earphone is established, the situation such as that the earphone is suddenly pulled out from the earphone box or the earphone is in an abnormal state or a sleep state may occur. At this moment, if the earphone box communicates immediately; data loss; program logic abnormality and the like may be caused. In order to deal with such a situation, after the first electrical contact is switched to the communication state, the earphone box immediately initiates a handshake to the earphone (that is, sends a handshake signal), and then switches the transceiving state of the first electrical contact to the RX receiving state, and waits for the earphone to feed back a handshake signal, so as to ensure that the earphone is in the earphone box and in a normal active state.
Optionally; after the earphone box switches the state of the first electrical contact to the communication state, the handshake signal can be transmitted to the second electrical contact (i.e., the earphone) through the first electrical contact, after the earphone receives the handshake signal transmitted from the earphone box, a handshake signal is also fed back to the earphone box. In this way, after the handshake signals are interchanged between the earphone box and the earphone, communication is formally established between the earphone box and the earphone.
Optionally, after the earphone box and the earphone establish the communication based on the first electrical contact, at this time, the earphone box is in a signaling state, the earphone is in a receiving state, and then, the process of data exchange is controlled by the earphone box, and TX data of the earphone box is transmitted in time to the earphone.
Optionally, the earphone box firstly sends the data cached in the TX buffer of the earphone box to the earphone, and sends an inquiry instruction to the earphone, so as to inquire whether there are data cached by the earphone to be sent to the earphone box. After the sending is finished, the earphone box is immediately switched to the receiving state. After receiving the inquiry instruction, the earphone switches from the RX receiving state to the TX signaling state. At this time, if there are data to be sent, the earphone can start to transmit the data after receiving the inquiry instruction until the TX buffer is emptied, and then the earphone sends an empty packet ack (namely a null data packet), that is, if the earphone does not have data to be transmitted, the earphone directly returns a null data packet, and after the data transmission is completed, the earphone actively switches from the TX signaling state to the RX receiving state, so as to indicate that the data to be transmitted has been sent. After the earphone box receives the empty ack sent from the earphone, the earphone box is switched from the RX receiving state to the TX signaling state immediately. In this way, one time of data exchange between the earphone box and the earphone is completed, and the next exchanging process is immediately initiated by the earphone box, till that there is no data exchange in multiple exchange processes. The two are returned back to the charging state again.
In one embodiment, when the first electrical contact is in the charging state, and the earphone box detects that there is a communication requirement between the earphone box and the earphone, the voltage level of the first electrical contact is adjusted to send preset signals to the earphone through the first electrical contact. When a response signal fed back by the earphone based on the preset signals is received, the first electrical contact is switched to the communication state. In this way, charging of the earphone box to the earphone and communication between the earphone box and the earphone can be realized based on the electrical contact, no additional communication contact is needed, the contacts between the TWS earphone and the earphone charging box is reduced, and the stability of the TWS earphone is improved.
In a second embodiment, with reference to
operation S30, detecting that the earphone box meets a first preset condition, and switching the first electrical contact to the charging state.
In this embodiment, the executive terminal is the earphone box.
Optionally, the first preset condition includes at least one of the following: the earphone box having no data to be sent to the earphone; no data being received from the earphone in a preset duration; a number of times of receiving an empty data packet from the earphone being greater than or equal to a second preset number of times; and detecting that the earphone is not fully charged.
The earphone box has no data to be sent to the earphone, that is, the data cached in the TX buffer of the earphone box have been sent.
The preset duration can be set by an engineer in advance according to the actual condition, which is not limited in this embodiment.
The number of times of receiving an empty data packet sent from the earphone is the counted number of times of the earphone continuously sending an empty data packet to the earphone box. The second preset number of times may be set by the engineer in advance according to the actual condition, which is optionally 5.
The earphone box can carry out power level detection on the earphone electrically connected with the earphone box in real time or regularly.
Optionally, when the earphone box detects that the first preset condition is met, the earphone box can determine that there is no communication requirement with the earphone, at this time, the earphone box switches the first electrical contact from the communication state to the charging state, so as to re-charge the earphone electrically connected with the earphone box.
Optionally, the first preset condition being met requires that two conditions, namely the earphone box having no data to be sent to the earphone and the number of times of receiving an empty data packet from the earphone being greater than or equal to the second preset number of times, are both met.
In one embodiment, when it is detected that the earphone box meets the first preset condition, the first electrical contact is switched to the charging state. In this way, by controlling the automatic switching of the first electrical contact between the communication state and the charging state, the effect of realizing communication and charging of the earphone based on the first electrical contact is optimized.
In a third embodiment, as shown in
operation S40, in responding to that the second electrical contact is in the charging state, and the earphone detects that the voltage level of the first electrical contact changes, performing detection of the preset signals.
operation S50, switching the second electrical contact to the communication state, and sending the response signal corresponding to the preset signals to the earphone box to establish the communication between the earphone and the earphone box.
In this embodiment, the executive terminal is the earphone.
Optionally, when the second electrical contact of the earphone is in the charging state, the second electrical contact is used for charging the earphone after being electrically connected with the first electrical contact of the earphone box. When the second electrical contact of the earphone is in the communication state, the second electrical contact is used for establishing the communication between the earphone and the earphone box after being electrically connected with the first electrical contact of the earphone box.
Optionally, when the second electrical contact is in the charging state, the earphone can be charged through the first electrical contact of the earphone box which is also in the charging state. At this time, when the earphone box detects that a communication requirement exists currently, the earphone box can firstly send the preset signals to the earphone through the first electrical contact to notify the earphone that, at current the earphone box needs to establish a communication with the earphone and needs to suspend the charging.
Optionally, the earphone box may alternately switch the voltage level of the first electrical contact between a low level (e.g., 0V) and a high level (e.g., 5V) for a first preset number of times, so as to send the preset signals to the earphone. Each time a switching operation of switching between the high level and the low level is performed, it is equivalent to generating one preset signal.
Further, in the process of switching the voltage level of the first electrical contact between the low level and the high level, the earphone box controls the time interval between two adjacent switching operations to be a preset interval.
It should be noted that the preset number of times and the preset interval may be set by an engineer in advance according to the actual condition, for example, the first preset number of times may optionally be 5, and the preset interval may optionally be 4 ms.
As shown in
Optionally, the second processor (MCU) of the earphone is provided with a PMU detection unit, which is configured for detecting the high and low levels of the first electrical contact electrically connected with the second electrical contact, that is, the switching between the high and low levels of the first electrical contact can be detected.
Optionally, when the second electrical contact is in the charging state, and the earphone detects that the voltage level of the first electrical contact changes, detecting the preset signals is performed. It should be noted that, when the earphone box effectively charges the earphone through the first electrical contact, the voltage level of the first electrical contact is the high level (5V). When the earphone detects that the first electrical contact jumps from the high level to the low level, detecting the preset signals is performed. Of cause, after the earphone detects that the first electrical contact jumps from the low level to the high level, the earphone can also determine that one preset signal is detected, so that the preset signals are detected by detecting the repeated jumping of the voltage level of the first electrical contact.
Optionally, after the earphone detects the preset signals formed by the earphone box based on the first electrical contact, the number of times of the detected preset signal can be identified (equivalent to that the total number of the rising edge signals and the falling edge signals of the pulse waveform signal is identified) as the preset signals, and whether the preset signals meet a second preset condition is judged based on the number of times of detection, the second preset condition includes the number of times of detection of the preset signals being greater than or equal to a first preset number of times.
Optionally, when the earphone detects that the number of times of detection of the preset signals is greater than or equal to the first preset number of times, the earphone determines that the preset signals meet the second preset condition, at this time, the earphone switches the second electrical contact from the charging state to the communication state to stop charging, switches the transceiving state of the second electrical contact in the communication state to the TX signaling state, and transmits the response signal obtained based on responding to the preset signals to the earphone box through the second electrical contact.
That is, when the earphone determines that the preset signals meet the second preset condition, executing the operation of switching the second electrical contact to the communication state, and sending the response signal corresponding to the preset signals to the earphone box, to establish the communication between the earphone and the earphone box (operation S50).
Optionally, when the earphone detects that the number of times of detection corresponding to the preset signals is less than the first preset number of times, the earphone determines that the preset signals do not meet the second preset condition. At this time, the earphone still controls the second electrical contact to maintain the charging state.
For example, when the preset number of times is 5, when the earphone detects that the number of times of detection of the preset signals is 6, the preset signals are judged to meet the second preset condition; and when the number of times of detection of the preset signal performed by the earphone is 3, the preset signals are judged not to meet the second preset condition.
Optionally, each time a preset signal is detected by the earphone, the number of times of detection is incremented by one.
In one embodiment, when the second electrical contact is in the charging state, and the earphone detects that the voltage level of the first electrical contact changes, detection of the preset signals is performed, the second electrical contact is switched to the communication state, and the response signal corresponding to the preset signals is sent to the earphone box to establish communication between the earphone and the earphone box. In this way, charging of the earphone box to the earphone and communication between the earphone box to the earphone can be realized based on the electrical contact without additionally adding a communication contact, and the stability of the TWS earphone is improved by reducing the number of contacts between the TWS earphone and the earphone charging box.
In a fourth embodiment, as shown in
operation S60, in responding to that a preset signal is detected, incrementing the number of times of detection of the preset signals by one, and detecting a next preset signal after a first duration;
operation S61, in responding to that the next preset signal is detected in a second duration after the first duration, incrementing the number of times of detection of the preset signals by one, and after the second duration, returning to execute the operation of in responding to that the preset signal is detected, incrementing the number of times of detection of the preset signals by one, and detecting the next preset signal after the first duration;
operation S62, in responding to that the next preset signal is not detected in the second duration after the first duration, and the number of times of detection of the preset signals is less than the first preset number of times, resetting the number of times of detection of the preset signals to zero.
In this embodiment, the executive terminal is the earphone.
Optionally, in the first duration timed from a preset signal is currently detected, detection of the preset signals is no longer performed. Even if a preset signal is detected within the first duration, the number of times of detection of the preset signals is not incremented. Then, after the first duration, and the detection of the preset signals is performed again within the second duration after the first duration, that is, if the earphone detects a next preset signal in the second duration, the number of times of detection is incremented by one. Then, after the second duration, the earphone returns to execute the operation of in responding to that the preset signal is detected, incrementing the number of times of detection of the preset signals by one, and detecting the next preset signal after the first duration (i.e., operation 60), and the first duration and the second duration are re-timed.
It should be understood that an end time point of the first duration is a start time point of the second duration. It should be noted that the first duration is less than the preset interval, and the sum of the first duration and the second duration is greater than the preset interval but less than twice the preset interval. For example, when the preset interval is 4 ms, the first duration may be 3 ms, and the second duration may be 2 ms.
Optionally, if the earphone does not detect a next preset signal in the second duration after the first duration, and the number of times of detection of the preset signals is less than the first preset number of times, the earphone resets the number of times of detection of the preset signals to be zero, and controls the second electrical contact to still in the charging state.
Optionally, if the earphone does not detect a next preset signal in the second duration after the first duration, and the number of times of detection of the preset signals is greater than or equal to the first preset number of times, the earphone switches the second electrical contact from the charging state to the communication state.
It should be noted that, whenever the earphone switches the second electrical contact from the charging state to the communication state, the number of times of detection is reset to zero.
Further, the earphone is further provided with a third duration, and the third duration can optionally be five times the preset interval. For example, when the preset interval is 4 ms, the third duration may be 20 ms.
Optionally, when a first preset signal is detected, the earphone starts to time the third duration, after the third duration ends, if the number of times of detection of the preset signals is less than the first preset number of times, the earphone resets the number of times of detection to be zero, and controls the second electrical contact to still in the charging state.
Optionally, effective detection of the preset signals can be achieved by providing the first duration, the second duration, and/or the third duration. That is, only a preset signal detected within a specified duration is counted as an effective signal, and the number of times of detection is incremented. Otherwise, the number of times of detection is not incremented, or the number of times of detection is reset to zero.
In this way, the situation that a user suddenly takes up the earphone, the pulse waveform signal is interrupted, and the next preset signal trigger will be influenced if there is no abnormal processing mechanism of effectively detecting the preset signals, can be avoided. Or, the situation that due to that the earphone is suddenly placed in the box, the sudden contact can cause mechanical vibration, jag interference on the communication line of the earphone box is caused, and a preset signal is generated passively can be avoided.
In this way, the earphone can be prevented from detecting an invalid preset signal and counting the invalid preset signal (the invalid preset signal is not actively initiated by the earphone box, but is generated due to external environmental factors).
In a fifth embodiment, as shown in
operation S70, in responding to that the earphone meets a third preset condition, switching the second electrical contact to the charging state.
In this embodiment, the executive terminal is the earphone.
Optionally, the third preset condition includes at least one of the following: the earphone having no data to be sent to the earphone box; no data being received from the earphone box in a preset duration; and a number of times of receiving an empty data packet from the earphone box being greater than or equal to a second preset number of times.
The earphone has no data to be sent to the earphone box, that is, the data cached in the TX buffer of the earphone have been sent.
The preset duration can be set by an engineer in advance according to the actual condition, which is not limited in this embodiment.
The number of times of receiving an empty data packet sent from the earphone box is the counted number of times of the earphone box continuously sending an empty data packet to the earphone. The second preset number of times may be set by the engineer in advance according to the actual condition, which is optionally 5.
Optionally, when the earphone detects that the third preset condition is met, the earphone can determine that there is no communication requirement with the earphone box, at this time, the earphone switches the second electrical contact from the communication state to the charging state, so as to re-charge based on the first electrical contact electrically connected with the second electrical contact.
Optionally, the third preset condition being met requires that two conditions, namely the earphone having no data to be sent to the earphone box and the number of times of the earphone receiving an empty data packet from the earphone box being greater than or equal to the second preset number of times, are both met.
In one embodiment, when it is detected that the earphone meets the third preset condition, the second electrical contact is switched to the charging state. In this way, by controlling the automatic switching of the second electrical contact between the communication state and the charging state, the effect of realizing communication and charging of the earphone based on one electrical contact is optimized.
