Detailed ways

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 in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

A flow chart of a specific embodiment of the power prompt method provided by the present invention is shown in FIG. 1 , the method is applied to a TWS earphone, and the TWS earphone includes a master earphone and a slave earphone set in pairs. In addition, the TWS headset also includes: a headset charging device used with the headset. The earphone charging device may specifically be an earphone charging box or an earphone charging base, wherein a cavity for accommodating the earphone is arranged inside the earphone charging box, and is used for charging the wireless earphone when the earphone is placed in the corresponding cavity; There is a slot for charging the wireless headset when the headset is placed on the corresponding slot.

The implementation process of the power prompt method specifically includes:

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

In this application, data transmission can be performed between the main earphone and the earphone charging device through a wireless communication protocol (such as Bluetooth). As a preferred implementation manner, in this embodiment, the main earphone communicates with the earphone charging device through BLE broadcast (Bluetooth low energy technology), and other methods are acceptable, which are not limited here.

There are many ways for the earphone charging device to detect that the main earphone is far away. A specific implementation method can be as follows: a communication connection is established between the earphone charging device and the main earphone, and the earphone charging device judges the main earphone by detecting the strength value of the received communication signal. Whether to stay away from the headset charging device. The lower the received communication signal strength value, the farther the distance between the main headset and the headset charging device. When the received communication signal strength value is lower than the preset strength threshold, it is determined that the main earphone is far away from the earphone charging device. The preset intensity threshold can be set according to the actual situation, which does not affect the realization 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 away from the earphone charging device is triggered, the subsequent power detection process is executed. By setting such a trigger condition, on the one hand, it can avoid the problem that the earphone cannot be used normally due to insufficient power after it is far away from the earphone charging device, and on the other hand, it also avoids the power consumption caused by the constant detection of the earphone power under normal conditions.

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

After receiving the power detection trigger instruction, the main earphone obtains the current remaining power of the earphone. It should be pointed out that the current remaining power of the earphone can be a smaller value determined after comparing the current remaining power of the master earphone and the current remaining power of the slave earphone, or it can be only the current remaining power of the master earphone, which does not affect this realization of the invention.

By comparing the current remaining power with the preset power threshold, it is determined whether the current power of the headset is sufficient. The preset power threshold can be set according to actual conditions. As a preferred implementation manner, in the embodiment of the present application, the preset power threshold is higher than the corresponding low power warning threshold when the earphone needs to be charged. For existing TWS earphones, when the current power level does not reach the low battery warning threshold, when the user only wears the earphones and does not carry the earphone charging device to go out, it is very likely that the battery power of the earphones will be exhausted and cannot continue to be used. However, this embodiment of the application can promptly remind the user Carry corresponding earphone charging equipment to keep the earphones fully charged when they are far away from the earphone charging equipment.

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 earphone determines that the current remaining power is lower than the preset power threshold, it sends out a charging prompt message. The charging prompt information can be played in the form of voice, for example, the voice message "Please bring the earphone charging device" is played through the main earphone. In order to achieve the purpose of effective reminder, when it is detected that the headset is not currently worn, the maximum volume that can be played by the headset is used for voice prompts. Of course, other methods can also be used for prompting, such as setting an indicator light on the earphone for prompting, which does not affect the realization of the present invention.

The power prompt method provided by the present invention is applied to TWS earphones. The main earphone receives the power detection trigger command sent by the earphone charging device, and the power detection trigger command is sent when the earphone charging device detects that the main earphone is far away; the main earphone obtains the current remaining power, And compare the current remaining power with the preset power threshold; when the current remaining power is lower than the preset power threshold, the main earphone sends a charging prompt message. The application uses the earphone charging device to detect whether the main earphone is far away, and when it is detected that the main earphone is far away, the main earphone is used to judge whether the power is sufficient, and if the power is too low, the user is prompted. This application avoids the problem that the TWS earphone cannot be used when the user goes out because the battery is too low and does not carry the earphone charging device, and improves the user experience of the product.

Referring to Fig. 2, another specific embodiment of the power prompt method provided by the present invention will be further elaborated below.

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

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

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

It should be pointed out that there is no time sequence between step S202 and step S203 in the embodiment of the present application. After step S201 receives the power detection trigger instruction, the master earphone and the slave earphone respectively detect their respective current remaining power.

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

Step S205: The main earphone 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 master earphone and the slave earphones have detected their current remaining power respectively, the master earphone performs data comparison, compares the first current remaining power corresponding to the master earphone with the second current remaining power corresponding to the slave earphone, and takes The smaller value of the two is used as the current remaining power for comparison with the preset power threshold.

Step S206: In the case that the current remaining power is lower than the preset power threshold, the master earphone sends a charging prompt message, and sends a first prompt trigger command to the slave earphone, so that the slave earphone sends out Charging reminder information.

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 earphone is insufficient, on the basis of the charging prompt message sent by the master earphone, this embodiment can also send a first prompt trigger command to the slave earphone through the master earphone , after receiving the first prompt trigger instruction, the slave earphone also sends a charging prompt message. Correspondingly, the charging prompt information may be played in a voice manner, for example, by playing the voice message "Please bring the earphone charging device" from the earphone. In order to achieve the purpose of effective reminder, when it is detected that the headset is not currently worn, the maximum volume that can be played by the headset is used for voice prompts. Of course, other methods can also be used for prompting, such as setting an indicator light on the earphone for prompting, which does not affect the realization of the present invention.

The flow chart of another specific embodiment of the power prompt method provided by the present invention is shown in Figure 3, the method includes:

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

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

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

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

In this embodiment, the main earphone first detects its own first current remaining power, and sends a charging prompt message when the power of the main earphone is insufficient. When it is judged that the power of the master earphone is sufficient, a power detection trigger command is sent to the slave earphone, and after receiving the command, the slave earphone performs a power judgment, and when the power of the slave earphone is insufficient, it sends a charging prompt message.

The charging prompt information may be played in a voice manner, for example, by playing the voice message "Please bring the earphone charging device" from the earphone. In order to achieve the purpose of effective reminder, when it is detected that the headset is not currently worn, the maximum volume that can be played by the headset is used for voice prompts. Of course, other methods can also be used for prompting, such as setting an indicator light on the earphone for prompting, which does not affect the realization of the present invention.

On the basis of any of the above-mentioned embodiments, the power prompt method provided by the present application may further include: the main earphone sends a second Prompting a trigger instruction, so that the earphone charging device sends a charging prompt message.

The charging prompt information issued 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 available, such as setting an indicator light on the earphone charging device for prompting, which does not affect the realization of the present invention.

In addition, the present application also provides a power prompt method, which is applied to an earphone charging device matched with a TWS earphone. The earphone charging device may specifically be an earphone charging box or an earphone charging base, wherein a cavity for accommodating the earphone is arranged inside the earphone charging box, and is used for charging the wireless earphone when the earphone is placed in the corresponding cavity; There is a slot for charging the wireless headset when the headset is placed on the corresponding slot.

In this application, data transmission can be performed between the main earphone and the earphone charging device through a wireless communication protocol (such as Bluetooth). As a preferred implementation manner, in this embodiment, the main earphone communicates with the earphone charging device through BLE broadcast (Bluetooth low energy technology), and other methods are acceptable, which are not limited here.

Referring to Fig. 4, the specific implementation flow chart of the power prompt method applied to the earphone charging device, the method specifically includes:

A communication connection is established between the earphone charging device and the main earphone, and the earphone charging device judges whether the main earphone is far away from the earphone charging device by detecting the received communication signal strength value. The lower the received communication signal strength value, the farther the distance between the main headset and the headset charging device. When the received communication signal strength value is lower than the preset strength threshold, it is determined that the main earphone is far away from the earphone charging device. The preset intensity threshold can be set according to the actual situation, which does not affect the realization 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.

The headset charging device judges 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, it is considered that the main earphone is moving away.

Step S402: When it is detected that the main earphone is far away from the earphone charging device, send a battery detection trigger command to the main earphone, so that the main earphone can obtain the current remaining power, and when the current remaining power is lower than the preset When the power threshold is exceeded, a charging prompt message will be 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 the main earphone receives the power detection trigger command, it performs subsequent power detection, judgment and prompt operations. When the main earphone determines that the current remaining power is lower than the preset power threshold, the earphone charging device may further receive a second prompt trigger instruction sent by the main earphone, and issue a charging prompt message.
