Description

Technical Field

[0001] This invention belongs to the field of athlete relaxation equipment technology, and in particular, a psychological relaxation auxiliary device specifically for athletes. Background Technology

[0002] Currently, the psychological relaxation intervention methods for athletes in the field of sports psychology are mainly divided into two categories: one is purely psychological intervention methods, including progressive muscle relaxation, mindfulness breathing relaxation, imagery relaxation, psychological suggestion, etc., which rely on verbal guidance from psychological teachers and audio playback to complete the intervention; the other is general civilian relaxation equipment, including ordinary sleep headphones, handheld massagers, heart rate bracelets and other general electronic products.

[0003] 2. Four major problems with existing technologies (1) Poor scene adaptability and cannot be adapted to the competitive arena environment. The arena environment is noisy and there is a large flow of people. Pure audio relaxation has weak anti-interference ability; athletes' physical activities are restricted before the competition and their hands need to be kept in competitive state. Handheld massagers need to be operated by hand, occupying both hands, and cannot be used in the pre-competition warm-up area, waiting area, or substitute bench.

[0004] (2) The physiological and psychological relaxation are disconnected, and the intervention lacks specificity. Existing equipment only monitors heart rate or plays relaxation audio separately, and cannot adaptively adjust the breathing guidance rhythm according to the athlete's real-time heart rate changes. The theory of sports psychology shows that physical physiological tension (heart rate spike, muscle stiffness) directly amplifies psychological anxiety, and single psychological counseling cannot simultaneously relieve physical stress, resulting in extremely low relaxation efficiency.

[0005] (3) The relaxation logic is not tailored to athletes, and general-purpose devices lack sports psychology expertise. Most civilian relaxation audio is general white noise and light music, without specific breathing rhythms or pre-competition mindfulness guidance scripts adapted to competitive sports. Athletes' tension is mostly concentrated in the three major muscle groups that exert force during exercise: shoulders, neck, back, and forearms. Ordinary massage devices cannot target and relax the muscle groups that are frequently stiff during exercise.

[0006] (4) The separate devices are cumbersome to carry and take too long to prepare before the competition. Before the competition, athletes need to wear heart rate bracelets, headphones and massage devices separately. Wearing multiple devices separately is cumbersome and the preparation time is tight. This can easily aggravate the athletes' irritability and go against the original intention of psychological relaxation. At the same time, the connection of multiple devices is complicated and the failure rate is high when used in emergency situations at the competition venue. Summary of the Invention

[0007] The purpose of this invention is to provide a psychological relaxation aid specifically for athletes, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a psychological relaxation aid device specifically for athletes, comprising: The neckband host contains a main control circuit board, a main control chip, an audio decoding chip, a lithium battery, a storage chip, status indicator lights, and a power switch. The flexible silicone neck brace frame is used to support the neck brace main unit and conform to the contours of the user's neck. A waterproof outer shell covers the neckband main unit, providing waterproof protection for the entire device; The left and right ear audio components are symmetrically located at both ends of the neckband main unit, each including an in-ear earbud structure and a built-in speaker. The heart rate detection fitting component integrates a photoelectric heart rate sensor and a flexible cushioning silicone pad for real-time acquisition of carotid artery heart rate data from athletes; The vibration relaxation module includes a vibration motor, a left shoulder and neck vibration massage patch, a right shoulder and neck vibration massage patch, and vibration contacts for the waist and back. The human-computer interaction module includes touch-sensitive adjustment buttons, mode switching buttons, volume buttons, and vibration intensity buttons; The main control chip is configured to receive heart rate data collected by the photoelectric heart rate sensor in real time, extract heart rate feature values ​​after filtering, amplification and analog-to-digital conversion, and compare them with a preset heart rate threshold. When the heart rate exceeds the threshold, the audio playback function and vibration relaxation function are automatically activated. The audio decoding chip is controlled to read and play breathing guidance audio, pre-competition mindfulness relaxation scripts, competition-specific low-frequency white noise, or progressive muscle relaxation guidance voice from the storage chip; The synchronous drive vibration motor enables the left shoulder and neck vibration massage patch, the right shoulder and neck vibration massage patch, and the waist and back vibration contact points to work together to perform low-frequency vibration relaxation on multiple parts of the body. Depending on the usage scenario, users can switch between pre-race rapid relaxation mode, in-race emergency adjustment mode, or post-race deep recovery mode via touch adjustment buttons.

[0009] Preferably, the flexible silicone neck frame has an arc-shaped bending structure, which can be flexibly bent to adapt to different athletes' neck circumferences. The main control circuit board integrates a main control chip, an audio decoding chip, a vibration motor drive circuit and a charging management module. The lithium battery has a preset capacity and the overall waterproof rating meets the IPX7 standard.

[0010] Preferably, the main control chip is configured to dynamically adjust the playback rhythm of the breathing guidance audio based on the real-time heart rate data from the photoelectric heart rate sensor, and synchronously adjust the output frequency and amplitude of the vibration motor to achieve closed-loop linkage between physiological monitoring and psychological intervention.

[0011] Preferably, the photoelectric heart rate sensor adopts a green light dual-wavelength photoelectric detection scheme, including two green light-emitting diodes and a photodiode detector, with a sampling frequency of 100Hz. The single heart rate value is obtained by averaging 10 consecutive samples. A flexible buffer silicone pad is provided on its outer side, which is made of low-hardness silicone with a Shore hardness of 20A to ensure that the sensor fits stably against the carotid artery and suppress motion artifact interference.

[0012] Preferably, the in-ear earbud structure in the left and right ear audio components adopts a cone-shaped in-ear angle design that conforms to the anatomy of the human ear canal, and the built-in speaker is a miniature dynamic speaker with a diameter of 8mm and an impedance of 32Ω.

[0013] Preferably, the storage chip pre-stores four types of motion psychology-specific audio: Standard breathing guidance audio, guide your breathing with a rhythm of 4 seconds of inhalation - 2 seconds of breath-holding - 6 seconds of exhalation; Pre-match mindfulness relaxation techniques, 3 minutes long, used to establish a positive mental state; Low-frequency white noise specifically designed for competitive sports, with a frequency range of 50–200Hz, and can be played continuously for 5 minutes; The progressive muscle relaxation guided voice lasts for 10 minutes, combined with vibration function to guide the muscles of the whole body to gradually relax.

[0014] Preferably, the left shoulder and neck vibration massage patch, the right shoulder and neck vibration massage patch, and the waist and back contact vibration points are all made of biocompatible silicone material with a thickness of 3mm. They can be detachably connected to the neckband host via magnetic attraction. The vibration frequency range is 5–30Hz, and the three vibration intensities correspond to amplitudes of 0.3mm (weak), 0.6mm (medium), and 1.0mm (strong), respectively.

[0015] Preferably, the touch adjustment button uses capacitive sensing technology, and its surface is flush with the waterproof shell, providing sweat and water resistance; the mode switching button is used to switch between three working modes, the volume button supports 8 levels of volume adjustment, and the vibration intensity button controls three levels of vibration intensity, supporting one-handed blind operation by athletes.

[0016] Preferably, it also includes an intelligent memory function module, controlled by the main control chip, which automatically saves the most recently used mode, volume and vibration intensity parameters, and automatically restores them when the device is turned on again, reducing the need for repeated settings.

[0017] Preferably, the three working modes are as follows: Pre-race rapid relaxation mode: Monitors heart rate with 100Hz high-frequency sampling, plays slow breathing guidance audio, and is combined with low-level vibration (0.3mm amplitude) to relieve pre-race tachycardia and hand tremors within 3 minutes; In-competition emergency adjustment mode: Plays concealed breathing guidance voice at a low volume (≤40dB) and simultaneously activates micro-vibration (0.2mm amplitude) to not affect the auditory environment of the competition venue, and is used for quick emotional calming after a mistake; Post-match deep recovery mode: Plays a full 10-minute progressive muscle relaxation audio, simultaneously activating medium-intensity vibration (0.8–1.0mm amplitude) on the shoulders, neck, and lower back to promote both physical and mental recovery.

[0018] Compared with the prior art, the technical effects and advantages of the present invention are as follows: This athlete-specific psychological relaxation aid device, with its neck-mounted, hands-free design, completely frees the athlete's hands and can be used in any scenario, such as waiting before a competition, being a substitute on the field, during training breaks, or in psychological classes. It is not limited by the venue or movement and is sweat-proof and waterproof, making it suitable for sweaty environments during sports activities. By using carotid artery heart rate acquisition to avoid data errors caused by wrist movement and vibration, the system can accurately identify athletes' hidden psychological stress and make relaxation intervention more targeted. At the same time, the built-in audio is all relaxation content specifically designed for sports psychology, which is in line with the athletes' on-site psychological patterns. The muscle relaxation points are designed for stiff areas where sports injuries are common, achieving two-way synergy between physiological and psychological relaxation. With its integrated design, it requires no Bluetooth or mobile phone and can be used immediately upon power-on. The blind operation touch button has zero learning cost before the competition, avoiding complicated operations that may aggravate athletes' anxiety. It can be used for sports psychology classroom training, allowing students to intuitively experience the physiological changes of physical and mental relaxation, assisting in the teaching of sports psychology, and has triple value in scientific research, teaching, and sports team practice.

[0030] In this embodiment, the status indicator 9 uses a tri-color LED, including red, green, and blue LED chips, with each color having a luminous intensity of 1000 to 1500 millicandela, a viewing angle of 120 degrees, and an operating temperature range of -40 degrees Celsius to 85 degrees Celsius. The power switch 10 is a side-press tactile switch with a rated mechanical life of 100,000 cycles, a button travel of 0.2 to 0.4 mm, and an operating force of 150 to 250 grams.

[0031] In this embodiment, the left ear audio component 11 and the right ear audio component 12 are symmetrically arranged at both ends of the neckband host 1. The left ear audio component 11 includes an in-ear earbud structure 13 and a built-in speaker 14; the right ear audio component 12 also includes an in-ear earbud structure 13 and a built-in speaker 14. The in-ear earbud structure 13 adopts a conical in-ear angle design based on the anatomical characteristics of the human ear canal, with the in-ear angle set in the range of 30 to 45 degrees, the length of the conical section being 10 to 15 mm, and the end diameter being 8 to 12 mm. The built-in speaker 14 adopts a miniature dynamic coil structure, with a diaphragm diameter of 10 mm, an impedance of 32 ohms, a frequency response range of 20 Hz to 20 kHz, a sensitivity of 95 dB / mW, a rated power of 5 mW, and a maximum power of 10 mW.

[0032] In this embodiment, the heart rate detection fitting component 15 is located at the center of the rear side of the neckband host 1, and includes a photoelectric heart rate sensor 16 and a flexible buffer silicone pad 17. The photoelectric heart rate sensor 16 adopts a green light dual-wavelength photoelectric detection scheme, including two green light-emitting diodes and a photodiode detector. The wavelengths of the light-emitting diodes are 525 nm and 570 nm, respectively, and the emission power is 3 to 5 milliwatts. The photosensitive area of ​​the detector is 0.5 square millimeters to 1 square millimeter. The sensor sampling frequency is set to 100 Hz, and a single heart rate data is obtained by averaging 64 consecutive samples. The measurement accuracy is ±3 times / minute, and the measurement range is 40 to 200 times / minute.

[0033] In this embodiment, a flexible buffer silicone pad 17 is disposed on the outside of the photoelectric heart rate sensor 16. It is made of low-hardness silicone material with a Shore A hardness of 10 to 15, a thickness of 2 to 4 mm, a width of 10 to 15 mm, and a length of 20 to 30 mm. The buffer pad ensures effective contact between the photoelectric heart rate sensor 16 and the carotid artery. The contact pressure is set in the range of 50 to 150 Pascals, and the contact angle is perpendicular to the direction of the carotid artery.

[0034] In this embodiment, the muscle vibration relaxation component includes a left shoulder and neck vibration massage patch 19, a right shoulder and neck vibration massage patch 20, and a waist and back contact vibration point 21. The left shoulder and neck vibration massage patch 19 and the right shoulder and neck vibration massage patch 20 are symmetrically arranged on the left and right sides of the neck hanger host 1, and each is electrically connected and mechanically fixed to the neck hanger host 1 through a detachable magnetic connector. The vibration massage patches 19 and 20 are made of biocompatible silicone material, with a thickness of 3 to 6 mm and a size ranging from 40×30 mm to 60×45 mm. The magnetic connector has a insertion and removal life of not less than 1000 times.

[0035] In this embodiment, the vibrating massage patch 1920 integrates a miniature flat vibration motor 18. The motor has a diameter of 10 to 15 mm, a thickness of 3 to 4 mm, a rated voltage of 3 volts, a rated current of 80 mA, and a vibration frequency set in the range of 30 to 80 Hz. The three vibration intensity levels are: weak (0.3 to 0.5 mm), medium (0.6 to 0.8 mm), and strong (0.9 to 1.2 mm), corresponding to vibration frequencies of 30 Hz, 50 Hz, and 80 Hz, respectively.

[0036] In this embodiment, the back-fitting vibration contact 21 is located at the center of the bottom of the neckband host 1 and is connected to the main body of the neckband host 1 via an elastic connecting arm. The elastic connecting arm is made of stainless steel spring wire, with a diameter of 1 to 2 mm and a length of 20 to 40 mm. The contact surface diameter of the back-fitting vibration contact 21 is 20 to 30 mm, and the contact angle is adjustable within a range of ±15 degrees to ensure effective contact with the upper back muscles.

[0037] In this embodiment, the touch-sensitive adjustment button 22 is located on the outside of the neckband host 1, including a mode switch button 23, a volume button 24, and a vibration intensity button 25. The touch-sensitive adjustment button 22 adopts capacitive sensing technology, with a button sensing area diameter of 8 to 10 mm, adjustable sensing sensitivity, and a response time of less than 50 milliseconds. The button surface is flush with the waterproof shell 3, achieving waterproof and sweatproof functions, and the surface is covered with a hydrophobic nano-coating with a contact angle greater than 110 degrees.

[0038] In this embodiment, the mode switch key 23 controls the cyclic switching of three working modes: pre-competition rapid relaxation mode, in-competition emergency adjustment mode, and post-competition deep recovery mode. The volume key 24 supports 8 levels of volume adjustment, ranging from 30 to 85 decibels, with each level increasing or decreasing by 8 decibels. The vibration intensity key 25 controls the switching of three vibration intensity levels. Athletes can operate the touch adjustment button 22 blindly with one hand without looking down at the device; operation feedback is provided by a 50-millisecond short vibration prompt generated by the vibration motor 18.

[0039] In this embodiment, the device also includes an intelligent memory function, which automatically saves the athlete's most recently used working mode, volume and vibration intensity settings to the non-volatile storage area of ​​the storage chip 8. After powering on, the main control chip 5 automatically reads the parameters and restores them to the state before powering off, reducing repeated settings.

[0040] This embodiment includes the following steps: Step 1: The photoelectric heart rate sensor 16 is attached to the carotid artery to continuously collect heart rate data at a sampling frequency of 100 Hz. A dual-wavelength green light source illuminates the skin; the reflected light is received by a photodiode and converted into an analog electrical signal. This signal is sampled by the 12-bit ADC built into the main control chip 5 (accuracy 1.22mV / LSB), and then filtered by a 5Hz FIR low-pass filter to remove motion artifacts. The signal is then amplified 1000 times by an instrumentation amplifier (CMRR>80dB), re-quantized, and the heart rate feature value is extracted using an autocorrelation algorithm (2-second window, 75% overlap). The heart rate is compared with preset thresholds: stress threshold 90 bpm, relaxation threshold 70 bpm.

[0041] Step 2: When the heart rate exceeds the tension threshold, the main control chip 5 activates the audio playback and vibration relaxation module. The audio decoding chip 6 reads and decodes the breathing guidance audio from the storage chip 8, and after power amplification, drives the left and right built-in speakers 14 to play the dedicated audio; at the same time, the main control chip 5 sends a PWM signal (frequency 1kHz, duty cycle 30%–80%) to the vibration motor drive circuit, activating the left shoulder and neck vibration massage patch 19, the right shoulder and neck vibration massage patch 20, and the waist and back contact vibration touch point 21 to perform low-frequency vibration.

[0042] Step 3: Storage chip 8 pre-stores four types of audio: Standard breathing guidance audio (4-7-8 breathing method, 19-second cycle); Pre-match mindfulness relaxation techniques (120 seconds, recorded by an expert); Low-frequency white noise for competitive use (50–200Hz, 300 seconds); Progressive muscle relaxation guided speech (600 seconds, head → feet sequence).

[0043] When the heart rate rises, it automatically plays breathing guidance audio and vibrates synchronously (breathing cycle: vibration frequency = 1:4); when the heart rate falls, it switches to mindfulness audio and reduces the vibration intensity.

[0044] Step 4: Apply the left shoulder and neck vibration massage patch 19 to the left trapezius and levator scapulae muscles; apply the right shoulder and neck vibration massage patch 20 to the corresponding muscle group on the right side; and apply the vibration contact point 21 to the lower middle section of the erector spinae muscles on the lower back. These three points work together to support continuous vibration (constant operation) or intermittent vibration (2 seconds on / 1 second off), and can be independently controlled in any combination.

[0045] Step 5: The athlete switches modes using the touch-sensitive adjustment button 22 with one hand and blind operation. Pre-race rapid relaxation mode: 100Hz heart rate sampling, low vibration, calms tachycardia within 180 seconds; In-competition emergency adjustment mode: 30-second interval sampling, ≤40dB concealed speech + micro-vibration, without affecting the listening experience in the competition venue; Post-match deep recovery mode: 600 seconds of full muscle relaxation voiceover + medium-high vibration (900 seconds).

[0046] The main control chip 5 dynamically adjusts the breathing guidance rhythm (proportional coefficient 0.5–2.0) and vibration frequency / amplitude according to the heart rate to achieve a closed-loop intervention of physiological and psychological factors.

[0047] When worn by athletes, the neckband unit 1 fits snugly against the neck, the photoelectric heart rate sensor 16 is aligned with the carotid artery, the left / right shoulder and neck vibration massage patches 19 / 20 fit against the shoulders and neck, and the lower back vibration contact 21 fits against the upper back. The device operates independently without external equipment. When the heart rate is abnormal, it automatically plays breathing guidance audio and starts vibration; when the heart rate returns to normal, it switches audio and reduces vibration.

[0048] The main control chip 5 executes the following data processing flow: It receives 0.5–2.5V analog signals output from the photoelectric heart rate sensor 16; ADC converts data into digital sequences; Preprocessing: DC removal, 0.5–4Hz fourth-order Butterworth bandpass filter; Adaptive threshold peak detection (initial threshold = maximum signal value × 60%). Heart rate is calculated using a moving average (window = 5 heartbeat cycles).

[0049] The main control chip 5 internally operates a five-state machine: standby → heart rate monitoring → tension intervention → relaxation transition → deep recovery. The state transition is triggered by the heart rate threshold and duration.

[0050] In this embodiment, the three working modes are implemented as follows: (1) Pre-competition rapid relaxation mode: power-on self-test, load parameters; 100Hz sampling, status indicator 9 displays heart rate status; heart rate > 90 bpm for 5 seconds → play breathing guidance audio + weak vibration (30Hz); breathing rhythm 4-7-8, vibration synchronized; heart rate < 75 bpm for 15 seconds → switch mindfulness audio + micro-vibration; automatic standby after 180 seconds.

[0051] (2) Emergency adjustment mode during the competition: switch mode with button 23, status indicator light 9 is yellow; heart rate sampling interval is 30 seconds; volume ≤ 40dB; intermittent vibration (60-second interval, 15 seconds / time, 40Hz); can be manually triggered for 60 seconds of breathing guidance; supports 120 minutes of continuous use.

[0052] (3) Post-match deep recovery mode: After switching, the status indicator light 9 is green; the heart rate sampling interval is 10 seconds; play 600 seconds of progressive muscle relaxation voice; left shoulder and neck vibration massage patch 19 and right shoulder and neck vibration massage patch 20, medium (50Hz), waist and back contact (21) strong (80Hz, 10s on / 5s off); heart rate <60bpm → switch background music + reduce vibration; after the end, prompt sound + low power standby.

[0053] In this embodiment, the device achieves hardware-software collaboration through the RTOS embedded in the main control chip 5: heart rate acquisition task (highest priority, 10ms cycle); heart rate calculation (100ms); heart rate analysis (500ms); audio playback (20ms); vibration control (50ms); touch scanning (100ms, low priority). Tasks communicate via message queues, supporting a watchdog timer (2-second timeout reset) and sleep / deep sleep modes (minimum power consumption <100μA).

[0054] In this embodiment, the storage chip 8 is divided into: a guidance area (256KB); a parameter configuration area (64KB, storing heart rate threshold, volume, vibration preference, etc.); an audio storage area (200Mbit: breathing guidance 4MB, mindfulness 2MB, white noise 8MB, muscle relaxation 12MB); and a log area (1MB, recording 100 usage summaries). Charging management supports standard charging (500mA, 3 hours) and fast charging (1000mA, 1.5 hours), and over-temperature protection (current reduction at >60℃).

[0055] In this embodiment, the battery level is displayed by the status indicator light 9: solid green: >80%; flashing green: 50–80%; solid yellow: 20–50%; solid red: 5–20%; flashing red: <5%.

[0056] In this embodiment, the main control chip 5 communicates with the audio decoding chip 6 via SPI (4MHz); it is controlled by the vibration motor 18 via GPIO+PWM (1kHz, 10–90% duty cycle); and it is connected to the capacitive touch chip via I²C with the touch adjustment button 22, supporting click / swipe gestures.

[0057] In this embodiment, the intelligent memory function writes each parameter change to the 8-parameter area of ​​the storage chip (erase first, then write, and verify); it automatically recovers upon power-on, and uses the default value if it fails.

[0058] In this embodiment, the assembly process includes: the main control circuit board 4 is fixed to the waterproof housing 3 with screws (torque 0.05–0.1 N·m); the lithium battery 7 is soldered to the main control circuit board 4 (350℃, ≤3s); the memory chip 8 is reflow soldered (peak temperature 245℃); the photoelectric heart rate sensor 16 and the flexible buffer silicone pad 17 are assembled into the heart rate detection fitting assembly 15 housing and filled with thermally conductive silicone grease; the left ear audio component 11 and the right ear audio component 12 are connected to the main control circuit board 4 through a foolproof connector; the left shoulder and neck vibration massage patch 19 and the right shoulder and neck vibration massage patch 20 are magnetically inserted (insertion force 2–5 N); the touch adjustment button 22 is embedded in the waterproof housing 3 (gap ≤0.05 mm); and the flexible silicone neck frame 2 is coated with the waterproof housing 3.

[0059] In this embodiment, the material selection is as follows: Waterproof shell 3: Liquid silicone (50 Shore A, sweat resistant); Photoelectric heart rate sensor 16 housing: Medical PC (compliant with ISO10993); Left shoulder and neck vibration massage patch 19 and right shoulder and neck vibration massage patch 20: Skin-friendly silicone, passed sensitization / irritation test.

[0060] Example 2 In this embodiment, the photoelectric heart rate sensor 16 adopts a multi-wavelength scheme: on the basis of the original green light (525nm, 570nm), 540nm green light and 940nm infrared light are added, for a total of 3 green + 2 infrared LEDs, in conjunction with 2 photodiodes, and the accuracy and anti-interference ability are improved through a weighted fusion algorithm.

[0061] The core formula of the weighted fusion algorithm is as follows: in This represents the fused heart rate value. This represents the heart rate value measured by the i-th wavelength channel. This represents the weighting coefficient of the i-th wavelength channel, and the weighting coefficient satisfies the normalization condition. The weighting coefficients are dynamically adjusted based on the signal quality of each channel. Signal quality is evaluated using two metrics: signal-to-noise ratio (SNR) and signal stability. Channels with an SNR higher than 40 dB have a weight of 0.3, channels with an SNR between 40 dB and 25 dB have a weight of 0.15, and channels with an SNR lower than 25 dB have a weight of 0.05.

[0062] In this embodiment, the left ear audio component 11 and the right ear audio component 12 are equipped with miniature microphones to realize ambient sound detection: when the ambient noise is >70 dB, the audio volume is automatically reduced; when a game broadcast or coach shouts is detected, playback is paused and resumed after 3 seconds.

[0063] In this embodiment, the left shoulder and neck vibration massage patch 19 and the right shoulder and neck vibration massage patch 20 are embedded with thin film pressure sensors (range 0–500 kPa, accuracy ±5 kPa): when the contact pressure is <50 kPa, the status indicator light 9 prompts the user to adjust the wearing position to ensure the vibration effect.
