Description

A wearable system, earphone charging box and earphone control method

This application claims the priority of the Chinese patent application submitted to the China Patent Office on July 28, 2021, with the application number 202110857907.X, and the title of the application is "A Wearable System, Headphone Charging Box and Headphone Control Method". The entire contents are incorporated by reference in this application.

technical field

The present application relates to the technical field of electronic equipment, in particular to a wearable system, a charging box for an earphone and a control method for an earphone.

Background technique

At present, TWS (True Wireless Stereo, True Wireless Stereo) earphones are being used more and more widely, and the design is becoming smaller and smaller. In order to improve the battery life, it will be equipped with a charging box to facilitate the storage and charging of the earphones. In order to use the limited power more efficiently, the following modes are usually configured for the charging case and earphones.

First, ship mode, that is, the transportation mode. After the headset leaves the factory, it will be stored and transported for a long time. In the transport mode, the power consumption of the charging box and the headset can be reduced to an extremely low level, and the transport mode will not exit until the user opens the charging box for the first time.

However, in the traditional design, it is detected by a single Hall sensor, so that when there is vibration during packaging and transportation, it is easy to make the upper case of the charging box slightly open and close. Once detected, it will exit the transportation mode. In addition, when there is external interference such as a magnet, it will also affect the state of the Hall sensor, so that even if the upper case of the charging box is not opened and closed, the Hall sensor will be falsely triggered due to interference, and then exit the transportation mode. The consequence of these situations is that the battery loses power, damages the lifespan, and reduces product reliability.

Second, sleep mode, that is, sleep mode. After the headset is placed in the charging case, the headset will disconnect from the Bluetooth connection, and the headset and charging case will enter sleep mode to save battery power. Correspondingly, the signal to exit the sleep mode is that the user opens the upper case of the charging box. However, in practical applications, users often play with the charging box like a toy, quickly opening and closing the upper case of the charging box, so the headset and charging box will repeatedly enter and exit sleep mode, and the headset will also turn on Bluetooth repeatedly. Connecting to the user's mobile phone and other devices consumes a lot of power, and the repeated connection of the headset to Bluetooth will also reduce the user's experience.

To sum up, how to effectively avoid vibration or interference from causing the charging box and earphones to exit the transport mode, and how to prevent the charging box and earphones from exiting the sleep mode when the user quickly opens and closes the upper case of the charging box, is the current state of the art. Technologists urgently need to solve technical problems.

Detailed ways

The core of this application is to provide a charging box for earphones, which can effectively prevent the charging box and earphones from exiting the transportation mode caused by vibration or interference, and prevent the charging box and earphones from exiting sleep when the user quickly opens and closes the upper case of the charging box. mode situation.

In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the drawings and specific implementation methods. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

Please refer to Figure 1a, Figure 1a is a schematic structural diagram of an earphone charging box in this application, the earphone charging box may include:

One master sensor 10 and at least one slave sensor 20, the master sensor 10 and each slave sensor 20 are used to detect the opening of the earphone charging box, and the trigger threshold of the opening stroke corresponding to the master sensor 10 is X%, each slave Sensors 20 all have respective trigger thresholds for unpacking trips and are all higher than X%; where;

The controller is configured to output a trigger signal to the earphone so that the earphone enters the working mode when both the master sensor 10 and each slave sensor 20 detect that the earphone charging box is opened.

Specifically, in the earphone charging box of the present application, in addition to the main sensor 10, each slave sensor 20 and the controller, the specific device configuration of the remaining components can be set and adjusted according to actual needs, and the function of the earphone charging box can be realized That is, it does not affect the implementation of the present application.

This application sets multiple sensors for the earphone charging box to detect the opening of the earphone charging box, that is, it specifically includes one master sensor 10 and at least one slave sensor 20. In the embodiment of Figure 1a, one For the master sensor 10 and the two slave sensors 20, in other occasions, the number, type and position of the sensors can be adjusted as required, as long as the purpose of this application can be achieved. Furthermore, the controller is not shown in FIG. 1a.

Both the main sensor 10 and each of the slave sensors 20 can detect the opening of the earphone charging box, that is, each sensor has the ability to independently complete the opening detection of the earphone charging box.

The trigger threshold of the unpacking stroke corresponding to the main sensor 10 is X%, and each slave sensor 20 has its own trigger threshold of the unpacking stroke, which is higher than X%. It is understandable that when the opening stroke of the earphone charging box is 0%, it means that the earphone charging box is completely closed, and as the earphone charging box is gradually opened, the opening stroke will gradually increase until when the earphone charging box is fully opened, The opening stroke of the earphone charging box reaches 100%.

Since the trigger threshold of the opening stroke corresponding to the main sensor 10 is X%, therefore, when the opening stroke of the earphone charging box is 0%, that is, when the earphone charging box is in the closed state in Fig. 2, the main sensor 10 and each slave sensor 20 will not confirm that the earphone charging box has been opened. The specific value of the trigger threshold X% of the unpacking stroke corresponding to the main sensor can be set and adjusted according to actual needs, for example, it can be set to 30% to 50%.

In the process of unpacking the earphone charging box, when the unpacking stroke of the earphone charging box reaches X%, the main sensor 10 will detect that the earphone charging box has been unpacked. And because each slave sensor 20 has its own trigger threshold for opening the box and is higher than X%, therefore, at this time, each slave sensor 20 will not detect that the earphone charging box is unpacked. In FIG. 2, the earphone charging box The opening stroke is greater than 0% and has not reached the state in which the master sensor 10 and each slave sensor 20 determine that the earphone charging case has been opened, which is called an interference state.

As the unpacking stroke of the earphone charging box continues to increase, for example, in one occasion, each slave sensor 20 will detect that the earphone charging box has been unpacked until the unpacking stroke of the earphone charging box reaches more than 80%. In FIG. 2 , the opening stroke of the earphone charging box reaches a state where the master sensor 10 and each slave sensor 20 can determine that the earphone charging box has been opened, which is called an open state.

When the main sensor 10 and each of the slave sensors 20 detect that the earphone charging box is opened, the controller can output a trigger signal to the earphone to make the earphone enter the working mode. On the contrary, if the main sensor 10 and each slave sensor 20 both detect that the earphone charging box is opened, the controller can keep the earphone box and the earphone in the original mode, that is, the mode will not be switched.

When the controller outputs a trigger signal to the earphone to enable the earphone to enter the working mode, the controller may first establish a communication connection with the earphone, and then the earphone and the user equipment are paired back to connect, for example, the earphone establishes a Bluetooth connection with the user's mobile phone.

It can be seen that in the solution of this application, multiple sensors are set in the earphone charging box, that is, one master sensor 10 and at least one slave sensor 20, and the master sensor 10 and each slave sensor 20 are used for earphone charging Box opening detection. When the main sensor 10 and each slave sensor 20 detect that the earphone charging box is opened, the controller will output a trigger signal to the earphone so that the earphone enters the working mode.

If the earphone charging box and the earphones are originally in the transportation mode, vibrations occur during packaging and transportation, since the trigger threshold of the unpacking stroke corresponding to the main sensor 10 is X%, each slave sensor 20 has its own unpacking stroke trigger threshold and are higher than X%, therefore, a slight vibration may only be detected by the master sensor 10, but it is not easy to trigger all the slave sensors 20, and the controller needs to be detected by the master sensor 10 and each slave sensor 20 When the earphone charging box is opened, the trigger signal will be output to the earphone to make the earphone enter the working mode. It can be seen that this application can avoid the situation that the earphone and the charging box will exit the transport mode abnormally due to vibration. Similarly, when interference occurs, compared with a single sensor, one master sensor 10 and each slave sensor 20 are less likely to be interfered, so that the application can effectively avoid the abnormal transportation of the charging box and earphones caused by interference mode or sleep mode. In addition, due to the different trigger thresholds of the unpacking strokes of each sensor, it means that the location and/or parameter setting and/or sensor type of each sensor are different, which makes it less likely for each sensor to appear in the face of interference. Both are affected by interference, and it is beneficial to further improve the anti-interference.

And the applicant considers that when the user plays the charging box like a toy, he generally opens and closes the upper shell of the charging box quickly, and the degree of opening of the upper shell is very low. Therefore, when this happens, in this application In the solution, only the main sensor 10 may detect the opening of the earphone charging box, but it is not easy to trigger each of the slave sensors 20, which makes the solution of this application prevent the user from quickly opening and closing the upper case of the charging box. Cases where the charging case and earbuds exit sleep mode.

This application requires that each slave sensor 20 has its own trigger threshold for unpacking travel, and all of them are higher than the trigger threshold X% of the corresponding master sensor 10. In order to achieve this goal, the master sensor 10 and each slave sensor can be adjusted 20 by setting position and/or parameter setting and/or sensor type etc. to realize. For example, the models of the master sensor 10 and each slave sensor 20 are exactly the same, and the position of each sensor is different, so that during the process of unpacking the earphone charging box, the master sensor 10 preferentially detects the opening of the earphone charging box. For another example, the master sensor 10 and each slave sensor 20 have exactly the same model, and the installation positions are roughly the same, but by setting the respective parameters of the master sensor 10 and each slave sensor 20, the master sensor 10 can be triggered preferentially.

In a specific implementation of the present application, the distance between the main sensor 10 and the opening shaft of the earphone charging box is greater than the distance between any one of the slave sensors 20 and the opening shaft.

This kind of implementation is a relatively simple and convenient implementation, that is, the functional distinction between the main sensor 10 and each slave sensor 20 is carried out through the distance from the box-opening shaft, and the main sensor 10 and each slave sensor 20 can be It is a device with the same type and parameter configuration, which is convenient for the implementation of the scheme.

In addition, it should be noted that the opening shaft can be regarded as a straight line, and any sensor can be regarded as a point. The distance between any sensor described in this application and the opening shaft of the earphone charging box refers to the sensor The vertical distance from the opening axis, that is, the distance from the point to the straight line. For example, in the embodiment of Fig. 1b, d0, d1 and d2 are sequentially used to represent the distance between the main sensor 10 and the opening shaft of the earphone charging box, and the distance between the first slave sensor H1 and the opening shaft of the earphone charging box , and the distance between the second slave sensor H2 and the opening shaft of the earphone charging box.

In a specific implementation of the present application, referring to FIG. 1b, the earphone charging box includes a first slave sensor H1 and a second slave sensor H2;

Moreover, the first slave sensor H1, the second slave sensor H2, the main sensor 10 and the unpacking shaft are all located on the same plane; and the first slave sensor H1 is arranged on the first side of the housing perpendicular to the unpacking shaft, and the second The two slave sensors H2 are arranged on the second side of the casing perpendicular to the box opening rotation axis, and the main sensor 10 is arranged on the long side of the casing parallel to the box opening rotation axis.

In this implementation manner, two slave sensors are provided, which is also a more commonly used implementation manner in practical applications, and the cost is relatively low, and the purpose of the present application can also be effectively achieved. In addition, the first slave sensor H1, the second slave sensor H2, and the main sensor 10 are arranged on the same plane as the unpacking shaft, so that each sensor can more easily realize the unpacking detection. Of course, in other embodiments, it can also be based on You will actually need to select a different specific location setting.

Further, in a specific embodiment of the present application, considering that in practical applications, the two slave sensors in the above-mentioned embodiment are generally selected on the side of the casing, and the main sensor 10 is arranged parallel to The scheme on the long side of the casing of the box-opening shaft, and the device models of the two slave sensors and the main sensor 10 are usually the same, so the trigger threshold of the box-opening stroke of the two slave sensors depends on the two slave sensors Each specific location on the side of the housing. In a specific implementation of the present application, considering that the respective trigger thresholds of the unpacking strokes of the slave sensors should have a certain difference from the corresponding trigger threshold X% of the unpacking strokes of the main sensor 10, thereby effectively achieving the goal of the present application To avoid the effect of false triggering, it is therefore set as follows: the distance between the first slave sensor H1 and the opening shaft of the earphone charging box is less than half the length of the first side; the distance between the second slave sensor H2 and the earphone charging box The distance between the opening hinges is less than half of the length value of the second side. In addition, the position of half the length of the first side and the position of half the length of the second side are also easy to determine during production.

The master sensor 10 and each slave sensor 20 of the present application can generally be Hall sensors or photoelectric sensors. In Figure 1b are Hall sensors. Moreover, in the embodiment shown in Fig. 1b, the earphone charging box includes an upper shell S1 and a lower shell S2, the main sensor 10, the first slave sensor H1, the second slave sensor H2 and the controller are all arranged on the lower shell S2 of the earphone charging box middle. This is because the master sensor 10 and each slave sensor need to communicate with the controller. Therefore, in practical applications, the master sensor 10, each slave sensor 20 and the controller can be arranged in a larger lower shell.

The Hall sensor can detect the opening of the box through the change of the magnetic field. Therefore, in the embodiment using the Hall sensor, magnets are usually arranged for each Hall sensor at the corresponding position of the upper shell. In FIG. 1 b , a magnet M0 corresponding to the master sensor 10 , a magnet M1 corresponding to the first slave sensor H1 , and a magnet M2 corresponding to the second slave sensor H2 are shown.

As the opening stroke of the earphone charging box gradually increases, the main sensor 10 can detect the opening of the earphone charging box, and at this time, each slave sensor 20 is still not high due to the distance from its corresponding magnet, so that each slave sensor 20 Opening of the earphone charging case will not be detected. As the opening stroke of the earphone charging box continues to increase, the distance between each slave sensor 20 and its corresponding magnet continues to increase, so that each slave sensor 20 can detect that the earphone charging box has been opened.

When a photoelectric sensor is used, the principle is similar to that of a Hall sensor. When the earphone charging box is slightly opened due to vibration or other reasons, the main sensor 10 arranged on the long side of the shell parallel to the opening shaft can receive sufficient light intensity to detect the opening of the earphone charging box, and it is arranged on the vertical The secondary sensor 20 on the side of the shell of the opening shaft is not easy to receive light, and it is not easy to detect the opening of the earphone charging box. However, it should be noted that the use of photoelectric sensors is more susceptible to errors due to the influence of ambient light. For example, when the ambient light is particularly strong, a slight opening of the earphone charging box will also cause each sensor to detect that the earphone charging box is open. Therefore, in practical applications Among them, Hall sensors are more used to realize the scheme of this application.

In a specific implementation manner of the present application, each slave sensor 20 has an enabling terminal;

The main sensor 10 is also used for: when detecting that the earphone charging box is unpacked, control each slave sensor 20 to switch from the non-working state to the working state through the enabling terminal of each slave sensor 20; when the earphone charging box is not detected to be unpacked , each slave sensor 20 is controlled to remain in a non-working state through the enable terminal of each slave sensor 20 .

In this embodiment, it is considered that the main sensor 10 is the first to detect the opening process of the earphone charging box. Therefore, when the main sensor 10 does not detect the opening of the earphone charging box, it is not necessary to enable each slave sensor 20, that is, the main The sensor 10 can control each slave sensor 20 to remain in a non-working state through the enable terminal of each slave sensor 20 , which is beneficial to save the energy consumption of each slave sensor 20 . Correspondingly, when the main sensor 10 detects that the earphone charging box is opened, each slave sensor 20 can be controlled to switch from the non-working state to the working state through the enabling terminal of each slave sensor 20 .

In the embodiment of FIG. 3 , the main sensor 10 controls the enabling terminals of the first slave sensor H1 and the second slave sensor H2 through its output pin, that is, int0. The pin realizes the control of the enable terminal of each slave sensor 20, which does not affect the implementation of the present application. In Fig. 3, the output int0 of the master sensor 10, the output int1 of the first slave sensor H1 and the output int2 of the second slave sensor H2 are received by the OR gate circuit. When the OR gate circuit outputs a high level, the controller can determine the master The sensor 10, the first slave sensor H1 and the second slave sensor H2 all detect the opening of the earphone charging box. In other implementation manners, the OR gate circuit may not be provided, that is, the output of each sensor may be directly connected to the controller, which does not affect the implementation of the present application. The controller in FIG. 3 can be specifically selected as MCU (Micro Controller Unit, micro control unit).

Further, in a specific implementation manner of the present application, it may also include:

The input terminal is connected to the main sensor 10, and the output terminal is connected to the delay circuit of each slave sensor 20. When the main sensor 10 detects that the earphone charging box is opened, after a first time delay, each slave sensor The enabling end of 20 controls each slave sensor 20 to switch from the non-working state to the working state.

In this embodiment, in order to further reduce the probability of false triggering, a delay circuit is set at the output end of the main sensor 10. When the main sensor 10 detects that the earphone charging box is opened, it will control each The slave sensor 20 switches from the non-working state to the working state.

Specifically, in some occasions, the user will quickly open and close the upper case of the charging box when playing with the earphone charging box, and the opening of the box is relatively large. Or the user has fully opened the earphone charging box, but suddenly does not want to use the earphone and closes the box immediately. In these cases, the main sensor 10 and each slave sensor 20 will detect that the earphone charging box is opened, but the user does not need to Use headphones. In this kind of embodiment, a delay circuit is set, so that even if the amplitude of opening the box is relatively large, the master sensor 10 will not immediately control each slave sensor 20 to switch from the non-working state to the working state. When the slave sensor 20 is switched to the working state, the earphone charging box has been closed by the user, or is in the process of closing the box so that the degree of opening the box is very low, so each slave sensor 20 or part of the slave sensor 20 will not detect the earphone charging Once the box is opened, the controller will not switch the earphones to the working state, which further reduces the probability of false triggering. There are many specific circuit configurations of the delay circuit, which can be selected according to needs. The specific value of the first duration can also be adjusted according to needs, for example, the specific value is set between 50 ms and 1 s.

In a specific implementation manner of the present application, the controller can also be used for:

When only the main sensor 10 detects that the earphone charging box is opened, a preset communication signal is output to the earphone to establish a communication connection with the earphone.

In this embodiment, when only the main sensor 10 detects that the earphone charging box has been opened, it means that the earphone charging box has not been fully opened. In this embodiment, the controller outputs a preset communication signal to the earphone to establish a connection The communication connection between the earphones makes it possible for the earphones to be paired with mobile phones and other devices immediately after the earphone charging box is fully opened. In this implementation mode, the communication between the earphone and the earphone charging box is established in advance, which reduces the time consumption of earphone activation and is beneficial to improve the user experience.

Corresponding to the above method embodiment, the embodiment of the present application also provides a headset control method, which can be applied to the headset charging box in any of the above embodiments, and can be referred to above.

Referring to Fig. 4, it is an implementation flowchart of an earphone control method in the present application, including:

Step S401: Receive the box-opening detection results of the earphone charging boxes of the master sensor and each slave sensor;

Step S402: When the master sensor and each slave sensor detect that the earphone charging box is opened, output a trigger signal to the earphone so that the earphone enters the working mode;

Among them, the earphone charging box includes 1 main sensor and at least 1 slave sensor, the main sensor and each slave sensor are used to detect the opening of the earphone charging box, and the trigger threshold of the opening trip corresponding to the main sensor is X%, Each slave sensor has its own trip trigger threshold and is higher than X%; wherein, .

In a specific implementation of the present application, the distance between the main sensor and the opening shaft of the earphone charging box is greater than the distance between any one of the slave sensors and the opening shaft.

In a specific implementation manner of the present application, the earphone charging box includes a first slave sensor and a second slave sensor;

And, the first slave sensor, the second slave sensor, the main sensor and the unpacking shaft are all located on the same plane; and the first slave sensor is arranged on the first side of the housing perpendicular to the unpacking shaft, and the second slave sensor is arranged On the second side of the casing perpendicular to the opening rotation axis, the main sensor is arranged on the long side of the casing parallel to the opening rotation axis.
