detailed description

In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

A flowchart of a specific embodiment of the power reminder method provided by the present invention is shown in FIG. 1. The method is applied to a TWS headset, which includes a master headset and a slave headset provided in pairs. In addition, the TWS headset also includes: headset charging equipment used with the headset. The earphone charging device may specifically be an earphone charging box or a earphone charging base. The earphone charging box is provided with a cavity housing the earphone for charging the wireless earphone when the earphone is placed in the corresponding cavity. The earphone charging base is provided on the earphone charging box. There is a card slot for charging the wireless headset when the headset is placed on the corresponding card slot.

The implementation process of the power reminder method specifically includes:

Step S101: the main earphone receives a power detection trigger instruction sent by the earphone charging device, and the power detection trigger instruction is sent when the earphone charging device detects that the main earphone is far away;

In this application, data can be transmitted between the main headset and the headset charging device through a wireless communication protocol (such as Bluetooth). As a preferred implementation manner, in this embodiment, the main headset communicates with the headset charging device through a BLE broadcast (Bluetooth Low Energy Technology) method, and other methods are possible, and are not limited herein.

There are various ways for the earphone charging device to detect the distance of the main earphone. One specific implementation method may be: establishing a communication connection between the earphone charging device and the main earphone, and the earphone charging device judges the main earphone by detecting the strength of the received communication signal. Are you away from the headset charging device. The lower the value of the received communication signal strength, the longer the distance between the main headset and the headset charging device. When the received communication signal strength value is lower than a preset strength threshold, it is determined that the main earphone is far from the earphone charging device. The preset intensity threshold can be set according to the actual situation, which does not affect the implementation of the present invention. The value of the preset intensity threshold cannot be set too large or too small, and an appropriate value is selected to determine whether the distance between the main earphone and the earphone charging device is within a reasonable and normal range.

When the earphone charging device detects that the main earphone is far away, it sends a power detection trigger instruction to the main earphone, so that the main earphone receives the power detection trigger instruction. That is, only after the trigger condition that the main earphone is far from the earphone charging device is triggered, the subsequent power detection process is performed. By setting such a triggering condition, on the one hand, the problem of insufficient power of the headset when it is far away from the charging device of the headset can be avoided, and on the other hand, power consumption caused by constantly detecting the power of the headset under normal circumstances is also avoided.

Step S102: the main headset obtains the current remaining power, and compares the current remaining power with a preset power threshold;

After receiving the power detection trigger command, the main headset obtains the current remaining power of the headset. It should be noted that the current remaining power of the headset may be a small value determined after comparing the current remaining power of the master headset and the current remaining power of the slave headset, or it may be only the current remaining power of the master headset, which does not affect this Realization of the invention.

By comparing the current remaining power with a preset power threshold, it is determined whether the power of the headset is sufficient. The preset power threshold can be set according to the actual situation. As a preferred implementation manner, the preset power threshold in the embodiment of the present application is higher than the low battery reminding threshold corresponding to when the headset needs to be charged. In the existing TWS headset, when the current battery level does not reach the low battery reminder threshold, when the user only wears the headset and does not carry the headset charging device when going out, it is very likely that the battery power of the headset is exhausted and cannot be used. Carry the corresponding headset charging device so that the headset maintains sufficient power when it is far away from the headset charging device.

Step S103: When the current remaining power is lower than the preset power threshold, the main earphone sends a charging prompt message.

When the main headset determines that the current remaining power is lower than a preset power threshold, it issues a charging prompt message. The charging prompt information may be specifically played in a voice manner, for example, a voice message of “Please bring a headset charging device” is played through a main headset. For the purpose of effective reminder, when it is detected that the headset is not currently worn, the headset can play the maximum volume for voice prompts. Of course, the prompting can also be implemented in other ways, such as setting an indicator on the headset for prompting, which does not affect the implementation of the present invention.

The power reminding method provided by the present invention is applied to a TWS headset. The main headset receives a power detection trigger instruction sent by the headset charging device. The power detection trigger instruction is sent when the headset charging device detects that the main headset is far away. The main headset obtains the current remaining power. The current remaining power is compared with a preset power threshold; when the current remaining power is lower than the preset power threshold, the main headset sends a charging prompt message. In this application, the headphone charging device is used to detect whether the main headphone is far away, and when the main headphone is detected to be far away, the main headphone is used to determine whether the power is sufficient, and if the power is too low, the user is prompted. This application avoids the problem that the TWS headset cannot be used when the user goes out because the battery is too low and the headset charging device is not carried, which improves the user experience of the product.

Referring to FIG. 2, another specific implementation of the power reminder method provided by the present invention is described in further detail below. In this method, the current remaining power of the master headset and the current remaining power of the slave headset are compared. Small value, this method specifically includes:

Step S201: The main earphone receives a power detection trigger instruction sent by the earphone charging device, and the power detection trigger instruction is sent when the earphone charging device detects that the main earphone is far away;

Step S202: the main headset detects its first current remaining power;

Step S203: the master headset sends a power detection trigger instruction to the slave headset, so that the slave headset detects its second current remaining power;

It should be noted that in the embodiment of the present application, there is no time limit between steps S202 and S203. After receiving the power detection trigger instruction in step S201, the master headset and the slave headset respectively detect their respective current remaining power.

Step S204: the master headset receives the second current remaining power sent by the slave headset;

Step S205: the main headset compares the first current remaining power with the second current remaining power, takes a smaller value as the current remaining power, and compares it with the preset power threshold;

In this embodiment, after the respective current remaining power of the master earphone and the slave earphone are detected respectively, the master earphone performs data comparison, and compares the first current remaining electricity power corresponding to the master earphone with the second current remaining electricity power corresponding to the slave earphone. The smaller value of the two is used as the current remaining power to compare with the preset power threshold.

Step S206: When the current remaining power is lower than the preset power threshold, the master headset sends a charging prompt message, and sends a first prompt trigger instruction to the slave headset, so that the slave headset issues Charging reminder.

When it is determined that the current remaining power is lower than the preset power threshold, that is, when it is determined that the current power of the headset is insufficient, based on the charging prompt information sent by the master headset, this embodiment may also send a first prompt trigger instruction to the slave headset through the master headset After receiving the first prompting trigger instruction, the slave headphone also sends a charging prompt message. Correspondingly, the charging prompt information may be specifically played in a voice manner, for example, by playing a voice message of “Please bring a headset charging device” from the headset. For the purpose of effective reminder, when it is detected that the headset is not currently worn, the headset can play the maximum volume for voice prompts. Of course, the prompting can also be implemented in other ways, such as setting an indicator on the headset for prompting, which does not affect the implementation of the present invention.

A flowchart of another specific implementation of the power reminder method provided by the present invention is shown in FIG. 3, and the method includes:

Step S301: the main earphone receives a power detection trigger instruction sent by the earphone charging device, and the power detection trigger instruction is sent when the earphone charging device detects that the main earphone is far away;

Step S302: the main headset detects its first current remaining power, and compares the current remaining power with the preset power threshold as the current remaining power;

Step S303: When the current remaining power is not lower than the preset power threshold, send a power detection trigger instruction to the slave headset, so that the slave headset detects its second current remaining power, and Sending a charging prompt message when the second current remaining power is lower than the preset power threshold;

Step S304: When the current remaining power is lower than the preset power threshold, the main headset sends a charging prompt message.

In this embodiment, the main earphone first detects its first current remaining power, and when the main earphone power is insufficient, a charging prompt message is sent. When it is determined that the power of the master headset is sufficient, a power detection trigger command is sent to the slave headset. After receiving the command from the headset, the power is judged, and when the power of the slave headset is insufficient, a charging prompt message is issued.

The charging prompt information may be specifically played in a voice manner, for example, by playing a voice message of “Please bring a headset charging device” from the headset. For the purpose of effective reminder, when it is detected that the headset is not currently worn, the headset can play the maximum volume for voice prompts. Of course, the prompting can also be implemented in other ways, such as setting an indicator on the headset for prompting, which does not affect the implementation of the present invention.

On the basis of any of the above embodiments, the power reminding method provided in the present application may further include: when determining that the current remaining power is lower than a preset power threshold, the main headset sends a second to the headset charging device. Prompt triggering instructions, so that the headset charging device sends charging prompt information.

The charging prompt message sent by the charging box can also be played by voice. Specifically, a speaker can be set on the earphone charging device for voice prompts. Of course, other prompting methods are possible, such as setting an indicator on the headset charging device for prompting, which does not affect the implementation of the present invention.

In addition, the present application also provides a power reminder method, which is applied to an earphone charging device supporting a TWS earphone. The earphone charging device may specifically be a earphone charging box or a earphone charging base. The earphone charging box is provided with a cavity for accommodating the earphone for charging the wireless earphone when the earphone is placed in the corresponding cavity. There is a card slot for charging the wireless headset when the headset is placed on the corresponding card slot.

In this application, data can be transmitted between the main headset and the headset charging device through a wireless communication protocol (such as Bluetooth). As a preferred implementation manner, in this embodiment, the main headset communicates with the headset charging device through a BLE broadcast (Bluetooth Low Energy Technology) method, and other methods are possible, which is not limited herein.

Referring to FIG. 4, which is a flowchart of a specific implementation method of a battery power reminding method applied to an earphone charging device, the method specifically includes:

Step S401: detecting whether the main earphone is far from the earphone charging device;

There are various ways for the earphone charging device to detect that the main earphone is far away. Referring to FIG. 5, a specific implementation manner may be:

Step S4011: Determine a communication signal strength value established between the main headset and the headset charging device;

Step S4012: Determine whether the main earphone is far from the earphone charging device according to the communication signal strength value.

A communication connection is established between the earphone charging device and the main earphone. The earphone charging device determines whether the main earphone is far away from the earphone charging device by detecting the received communication signal strength value. The lower the value of the received communication signal strength, the longer the distance between the main headset and the headset charging device. When the received communication signal strength value is lower than a preset strength threshold, it is determined that the main earphone is far from the earphone charging device. The preset intensity threshold can be set according to the actual situation, which does not affect the implementation of the present invention. The value of the preset intensity threshold cannot be set too large or too small, and an appropriate value is selected to determine whether the distance between the main earphone and the earphone charging device is within a reasonable and normal range.

Specifically, after the TWS headset is worn, the main headset performs BLE broadcast, and the headset charging device performs BLE scan. The headset charging device determines whether the headset is far away according to the strength of the received BLE broadcast signal. Specifically, it can be judged according to the RSSI value, if the signal is getting weaker and weaker. If the value is lower than the preset threshold, the main headphone is considered to be away.

Step S402: When it is detected that the main earphone is far from the earphone charging device, send a power detection trigger instruction to the main earphone, so that the main earphone obtains the current remaining power, and when the current remaining power is lower than a preset In the case of a battery threshold, a charging prompt message is issued.

When the earphone charging device detects that the main earphone is far away, it sends a power detection trigger instruction to the main earphone. After receiving the power detection trigger instruction, the main headset performs subsequent power detection, judgment, and prompt operations. When the main headset determines that the current remaining power is lower than a preset power threshold, the headset charging device may further receive a second prompt trigger instruction sent by the main headset, and issue a charging prompt message.
