In the above-mentioned technical solutions, there is a biggest problem that the judgment error is large. All acquire real-time parameter for the multiaxis sensor among the above-mentioned technical scheme, then compare this parameter with preset parameter, the error that this kind of detection leads to is great, and misjudgment can appear in many times, leads to the wrong warning, influences user's normal use. Based on the above, the present inventors propose the following.

The invention content is as follows:

the invention aims to overcome the defects of the prior art and provides a TWS earphone sitting posture health detection method, which can accurately judge whether the sitting posture of a user is healthy or not, reduce misjudgment and improve user experience.

In order to solve the technical problems, the invention adopts the following technical scheme: a TWS earphone sitting posture health detection method comprises a left earphone and a right earphone, data wireless transmission is carried out between the left earphone and the right earphone through a Bluetooth module, gyroscope modules with the same specification are respectively integrated in the left earphone and the right earphone, and the detection method comprises the following steps: first, a comparison parameter S1 is preset in the TWS headset, and the method for obtaining the comparison parameter S1 is as follows: under the condition that the TWS earphone product is worn in a sitting posture, acquiring parameters of gyroscope modules in the left earphone and the right earphone, and carrying out differential comparison on the parameters of the left earphone and the right earphone to obtain a numerical range of a comparison parameter S1 of the left earphone and the right earphone; secondly, after a user correctly wears the TWS earphone and starts to use the TWS earphone, the main controller in the left earphone reads the parameter SL of the gyroscope module at a certain time interval T, and sends the parameter SL to the right earphone through the Bluetooth module; then, after receiving the parameter SL sent by the left earphone through the Bluetooth module, the right earphone acquires the parameter SR of the gyroscope module of the right earphone; finally, the right headphone performs difference comparison on the corresponding parameters SL and SR data in the left and right headphones to obtain an actual parameter S2: if the S2 is not in the numerical range of S1, the right earphone sends out a voice prompt, and simultaneously the actual parameters S2 are sent to the left earphone through the Bluetooth module, and the left earphone also sends out the voice prompt; if S2 is in the value range of S1, the left and right earphones continue to work and wait for detection after the next time T.

Further, in the above technical solution, the left and right earphones each include: the device comprises a main controller, and a power module, an ear-entering detection module, a gyroscope module, a Bluetooth module, an audio playing module and a key module which are connected with the main controller.

After adopting the technical scheme, compared with the prior art, the invention has the following beneficial effects: the invention is used for the TWS earphone and realizes the data transmission of the left earphone and the right earphone through Bluetooth. Meanwhile, in order to improve the accuracy of judgment, the invention does not directly compare the real-time parameters of the gyroscopes in the left and right earphones with the preset values, but compares the gyroscope parameters of the left and right earphones with each other, compares the actual comparison values with the preset values, and judges whether the sitting posture is correct or not according to the final comparison result. The biggest advantage of adopting the method is accurate judgment. Because in certain situations, for example, the human body may lean forward and lean backward relative to the horizontal due to external factors (e.g., riding in a vehicle, etc.). However, at this time, the sitting posture of the human body is not in an incorrect state, and if the method in the prior art is adopted, the result is misjudged. The invention overcomes the defects, and can eliminate misjudgment caused by non-human sitting postures according to the mutual comparison of the gyroscope parameters of the left and right earphones, thereby greatly improving the judgment accuracy and improving the use experience of users.

Description of the drawings:

fig. 1 is a schematic diagram of a TWS headset of the present invention.

The specific implementation mode is as follows:

the present invention will be further described with reference to the following specific examples.

The invention relates to a TWS earphone sitting posture health detection method. The earphone be TWS earphone because two earphones can realize independent work through wireless bluetooth about TWS earphone to the realization is to controlling the independent regulation of earphone. As shown in fig. 1, the left earphone 1 and the earphone 2 respectively include: main controllers 10, 20, and

power supply modules

11, 21 connected to the main controllers; an in-ear detection module 12, 22;

gyroscope modules

13, 23; bluetooth modules 14, 24; audio playback modules 15, 25; key modules 16, 26.

The controller can adopt QCC Bluetooth SoC type controller, and is used for controlling each function module to work, read, write and process data.

A power supply module: and power is supplied to all functional modules of the earphone.

An in-ear detection module: whether the earphone is normally worn in the using process is detected.

A gyroscope module: the earphone physical state detection device can provide state information of the earphone such as horizontal, vertical and pitching. For improving the accuracy, the

gyro modules

13 and 23 may be nine-axis gyro modules.

A Bluetooth module: the earphone is used for transmitting data information of the left earphone and the right earphone and exchanging data.

The audio playing module: for playing audio.

A key module: the user and the headset are in control interaction.

The detection method comprises the following steps:

first, a comparison parameter S1 is preset in the TWS headset, and the method for obtaining the comparison parameter S1 is as follows: under the condition that the TWS earphone product is worn in a sitting posture, the parameters of the gyroscope modules in the left earphone and the right earphone are obtained, and the parameters of the left earphone and the right earphone are subjected to differential comparison to obtain the numerical range of a comparison parameter S1 of the left earphone and the right earphone. In obtaining the comparison parameter S1, special situations, such as forward inclination and backward inclination relative to the horizontal plane, should be considered as much as possible. In this case, the sitting posture of the human body is not in an untidy state.

Secondly, after the user wears the TWS earphone correctly and starts using the TWS earphone, when the user triggers the earphone to start up through the key module, the main controller and other corresponding functional modules start working. When the in-ear detection module detects that the earphone is normally worn, the main controller is informed, and the earphone starts to work. In the working process, the main controller in the left earphone reads the parameter SL of the self gyroscope module once at a certain time interval, and sends the parameter SL to the right earphone through the Bluetooth module.

Then, after receiving the parameter SL sent by the left earphone through the Bluetooth module, the right earphone acquires the parameter SR of the gyroscope module of the right earphone;

finally, the right headphone compares the corresponding parameter SL and SR data in the left and right headphones differentially to obtain an actual parameter S2, and compares the comparison parameter S1 with the actual parameter S2. The specific comparison method is as follows:

(1) if the S2 is not in the numerical range of S1, the right earphone sends out a voice prompt, and simultaneously the actual parameters S2 are sent to the left earphone through the Bluetooth module, and the left earphone also sends out the voice prompt;

(2) if S2 is in the value range of S1, the left and right earphones continue to work and wait for detection after the next time T.

In the invention, the value range of the time T is as follows: 5-60 seconds. When the value is smaller, the detection frequency is higher, which may affect the user experience, so that a proper time value can be selected according to specific situations.

The method has the greatest advantage of accurate judgment, because the parameters of the actual gyroscope are not directly compared with the standard parameters, and in order to reduce misjudgment, the parameters of the gyroscope of the left earphone and the right earphone are compared with each other, so that some misjudgment caused by non-human sitting postures can be eliminated, the judgment accuracy is greatly improved, and the use experience of a user is improved.

It should be understood that the above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention, which is defined by the appended claims.
