[0002] With the change of modern lifestyle, people spend long hours working at desks and using electronic devices, which has led to the increasing prevalence of cervical spine problems. As a common medical rehabilitation device, neck massagers are favored by many users.

[0003] Existing massage devices offer relatively simple adjustment methods, often employing a fixed, clamping structure that makes it difficult to adapt to individual differences in neck curves and dynamic massage needs. Neck size, shape, and cervical curvature vary significantly between users, and a fixed structure cannot meet these individual needs, resulting in poor effective fit between the massage head and the skin of the neck. During the massage, the massage head can easily lose contact with the neck or experience excessive pressure. Loss of contact significantly reduces the effectiveness of the massage, preventing accurate stimulation and relaxation of the cervical spine and surrounding muscles. Excessive pressure, on the other hand, can cause discomfort and reduce the user experience.

[0035] The implementation details of the cervical spine massage method capable of measuring the cervical curvature in this embodiment are specifically described below. The following content is only the implementation details provided for convenient understanding and is not necessary for implementing this solution. The specific process of this embodiment is as Figure 4 shown, this embodiment is applied to a cervical spine massage device capable of measuring the cervical curvature.

[0036] Step S1, obtain the motion data of the cervical spine part through the triaxial acceleration sensor built into the massage mechanism and the motion data of the head through the triaxial acceleration sensor integrated inside the earphone.

[0037] Specifically, the specific steps of obtaining the motion data of the cervical spine part through the triaxial acceleration sensor built into the massage mechanism and the motion data of the head through the triaxial acceleration sensor integrated inside the earphone include: Step S11, obtain the motion data of the cervical spine part through the triaxial acceleration sensor built into the massage mechanism.

[0038] Specifically, the triaxial acceleration sensor built into the massage mechanism is closely attached to the back of the neck, and the model of the triaxial acceleration sensor built into the massage mechanism is ADXL345, which real-time collects the acceleration signals (X, Y, Z axes, unit m / s²) in the three-dimensional space of the neck as the motion data of the cervical spine part. The triaxial acceleration sensor built into the massage mechanism focuses on capturing the dynamic posture of the neck.

[0039] As an example, collect the forward acceleration when looking down at the mobile phone or the backward acceleration when stretching the head backward.

[0040] Step S12: Obtain the motion data of the head through a three-axis acceleration sensor integrated inside the earphone.

[0041] Specifically, the three-axis acceleration sensor integrated inside the earphone is located inside the ear, and the model of the three-axis acceleration sensor integrated inside the earphone is ADXL345. It synchronously and real-time collects the acceleration signals (X, Y, Z axes, unit: m / s²) of the head in the same three-dimensional space as the motion data of the head, and the motion data of the cervical vertebra part is time-stamped with the motion data of the head.

[0042] Step S13: Send the motion data of the cervical vertebra part and the motion data of the head to the main control chip.

[0043] Step S2: Obtain the muscle state data of the cervical vertebra part through electrode patches.

[0044] Specifically, the specific steps for obtaining the muscle state data of the cervical vertebra part through electrode patches include: Step S21: After the electrode patch is attached to the cervical vertebra part, the electrode patch receives an activation signal, and at this time the electrode patch enters the working state. When the user's neck muscles contract or relax, weak bioelectric signals will be generated, and the bioelectric signals are detected by the electrode patch and converted into electric signals; then the electric signals collected by the electrode patch are transmitted to the main control chip through a conductive line.

[0045] Step S22: The main control chip preprocesses the collected muscle electric signals, including preprocessing operations such as amplification and filtering, to remove interference signals, improve the signal-to-noise ratio of the signal, and ensure the accuracy and reliability of the signal.

[0046] Step S23: Extract features from the preprocessed muscle electric signals to obtain muscle state data. Among them, feature extraction includes calculating the root mean square value and the integrated electromyogram value. The muscle state data includes the muscle contraction intensity and the degree of muscle fatigue accumulation.

[0047] Specifically, the formula for calculating the root mean square value is:

[0048] where RMS is the root mean square value, N is the number of sampling points in the sliding window, the amplitude of the muscle electric signal at the i-th sampling point, is the sum of the squares of the amplitudes of all sampling points in the sliding window.

[0049] Furthermore, the root mean square (RMS) value can reflect the average electrical activity intensity of muscle contraction, that is, the muscle contraction intensity. The larger the RMS value, the more tense the muscle and the higher the muscle contraction intensity.

[0050] The integrated electromyogram (IEMG) value is calculated as the sum of the absolute values of the signals within the sliding window, and the IEMG value is used to evaluate the degree of muscle fatigue accumulation. The higher the IEMG value, the greater the degree of muscle fatigue accumulation.

[0051] Step S3: Obtain the cervical curvature data by using the relative angle algorithm based on the motion data of the cervical part and the motion data of the head.

[0052] Specifically, the specific steps of obtaining the cervical curvature data by using the relative angle algorithm based on the motion data of the cervical part and the motion data of the head include: Step S31: Calculate the pitch angle of the cervical part according to the motion data of the cervical part.

[0053] Specifically, the calculation formula for the pitch angle of the cervical part is:

[0054] Where, is the pitch angle of the cervical part, is the acceleration value of the triaxial acceleration sensor located in the neck in the Z-axis (vertical) direction, is the acceleration value of the triaxial acceleration sensor located in the neck in the X-axis (front-back) direction, is the acceleration value of the triaxial acceleration sensor located in the neck in the Y-axis (left-right) direction.

[0055] Furthermore, the pitch angle of the cervical part has a positive value corresponding to the forward tilt of the neck and a negative value corresponding to the backward tilt of the neck.

[0056] Step S32: Calculate the pitch angle of the head according to the motion data of the head.

[0057] Specifically, the calculation formula for the pitch angle of the head is:

[0058] Where, is the pitch angle of the head, is the acceleration value of the triaxial acceleration sensor located in the head in the Z-axis (vertical) direction, is the acceleration value of the triaxial acceleration sensor located in the head in the X-axis (front-back) direction, is the acceleration value of the triaxial acceleration sensor located in the head in the Y-axis (left-right) direction.

[0059] Furthermore, the pitch angle of the head Positive values correspond to forward neck inclination, and negative values correspond to backward neck inclination.

[0060] Step S33: Calculate the cervical curvature data based on the pitch angles of the cervical vertebrae part and the head.

[0061] Specifically, the cervical curvature data is the difference in pitch angles between the head and the cervical vertebrae part. The calculation formula for the cervical curvature data is:

[0062] where, is the cervical curvature data, is the pitch angle of the head, is the pitch angle of the cervical vertebrae part.

[0063] Further, when the cervical curvature is normal; when the cervical curvature is straight; when the cervical curvature has excessive lordosis.

[0064] Step S34: Transmit the calculated cervical curvature data to the mobile APP terminal in real time via Bluetooth so that the user can intuitively view their own cervical physiological state.

[0065] Step S4: Conduct a comprehensive analysis based on the cervical curvature data and the muscle state data to generate corresponding massage strategies.

[0066] Specifically, for the cervical curvature data when the cervical curvature is normal; when the cervical curvature is straight; when the cervical curvature has excessive lordosis.

[0067] As an example, when it is determined that the cervical curvature is straight; when it is determined that the cervical curvature has excessive lordosis.

[0068] For the muscle state data, the muscle tension and fatigue degree are judged by the output root mean square value RMS and the integrated electromyogram value IEMG. When RMS < 30mV, it is judged that the muscle is relaxed; when 30mV ≤ RMS ≤ 60mV, it is judged that the muscle is slightly tense; when RMS > 60mV, it is judged that the muscle is severely tense; when IEMG > 50mV·s, it is judged that the muscle fatigue accumulates significantly.

[0069] The judgment of the massage strategy includes: when the cervical curvature becomes straight or the cervical curvature has excessive lordosis, the massage strategy is to first use the correction prompt mode to adjust the cervical curvature to normal; when the cervical curvature is normal and the muscles are relaxed, the massage strategy is judged as the basic mode; when the cervical curvature is normal and the muscles are slightly tense, the massage strategy is judged as the soothing mode; when the cervical curvature is normal and the muscles are severely tense, the massage strategy is judged as the relaxation mode; when the cervical curvature is normal and the muscle fatigue accumulation is significant, the massage strategy is judged as the relaxation mode.

[0070] Step S5, output corresponding control signals according to the corresponding massage strategy and send them to the electrode patches, and then output corresponding pulse intensities for massage.

[0071] Specifically, when the massage strategy is the basic mode, the control signal sent is to output a low-frequency sine wave for uniform stimulation in the whole area, simulating the kneading technique for soothing and relaxation.

[0072] When the massage strategy is the soothing mode, the control signal sent is to output a medium-frequency square wave for simulating the tapping technique to relieve muscle stiffness.

[0073] When the massage strategy is the relaxation mode, the control signal sent is to alternately output low frequency and high frequency, and output a sawtooth wave for deep stimulation in the whole area, while simulating the kneading technique for relaxation.

[0074] When the massage strategy is the correction prompt mode, the user is prompted to adjust the posture through voice.

[0075] Furthermore, the frequency setting of the control signal is generated by the timer module of the main control chip to generate specified frequency pulses, and the waveform setting of the control signal is controlled by a digital signal to switch the sine wave or square wave or sawtooth wave generating circuit.

[0076] Step S6, when the user adopts the manual adjustment mode, the manual adjustment mode is preferentially used for massage.

[0077] Specifically, when the user adopts the manual adjustment mode, the current ongoing automatic massage process will be paused, and according to the user's manual adjustment instructions, the main control chip will adjust the corresponding massage parameters.

[0078] As an example, if the user presses the button to increase the massage intensity, the pulse intensity will be appropriately increased; if the user presses the button to switch the massage mode, it will switch to the massage mode selected by the user.

[0079] Subsequently, according to the adjusted massage parameters, corresponding control signals are generated and sent to the electrode patches, so that they output the pulse intensity and waveform corresponding to the manual adjustment mode for massage. Subsequently, it continuously monitors whether the user presses the button to exit the manual adjustment mode. If no exit instruction is detected, the manual adjustment massage mode is continued; if an exit instruction is detected, the automatic massage process is restored. After restoring the automatic massage process, the triaxial acceleration sensor continuously collects data and returns to step S1.

[0080] A cervical spine massage method capable of measuring the cervical spine curvature of the present invention includes obtaining the motion data of the cervical spine part through a triaxial acceleration sensor built in the massage mechanism and obtaining the motion data of the head through a triaxial acceleration sensor integrated inside the earphone; obtaining the muscle state data of the cervical spine part through the electrode patches; obtaining the cervical spine curvature data by using the relative angle algorithm according to the motion data of the cervical spine part and the motion data of the head; comprehensively analyzing according to the cervical spine curvature data and the muscle state data to generate a corresponding massage strategy; outputting corresponding control signals according to the corresponding massage strategy and sending them to the electrode patches, and then outputting the corresponding pulse intensity for massage; when the user adopts the manual adjustment mode, the manual adjustment mode is preferentially adopted for massage. The present invention uses the triaxial acceleration sensors built in the massage mechanism and the earphone to synchronously collect the motion data of the cervical spine and the head, combines the muscle state data obtained by the electrode patches, accurately calculates the cervical spine curvature through the relative angle algorithm and judges the cervical spine state, and at the same time analyzes the muscle tension and fatigue degree, and then automatically generates and outputs a targeted massage strategy, matching different pulse intensities and waveforms, so as to realize the accurate identification of cervical spine problems and personalized massage adjustment; and supports the priority response of the manual adjustment mode, improves the use flexibility, and finally optimizes the massage effect through data drive, helps users scientifically understand the cervical spine health status and achieve efficient rehabilitation and relaxation.
