Description

Technical Field

[0001] The present invention relates to the technical field of vocalization trainers, and in particular, to a multifunctional swallowing training and vocalization assistance exerciser. Background Art

[0002] A swallowing training and vocalization assistance exerciser is a device used to help patients improve their swallowing and vocalization functions. By providing different stimuli and exercises, it helps patients enhance the strength and coordination of the swallowing muscles, thereby effectively reducing the situation of dysphagia. Through specific vocalization exercises, it helps patients improve the clarity, intensity, and persistence of their voices, and is especially suitable for patients with vocal cord diseases and professional vocal musicians, etc.

[0003] As shown in the existing vocalization trainer, such as the Chinese patent with the application number: 201811224559.7, an orthosis for assisting vocal cord closure training and vocalization, this device includes: an inner arc plate, an outer arc plate, and two oppositely arranged partitions. The inner arc plate is arranged opposite to the outer arc plate, and the two partitions are arranged at intervals between the inner arc plate and the outer arc plate. The two partitions, the inner arc plate, and the outer arc plate enclose a receiving cavity, and the receiving cavity is divided in the height direction into an upper receiving cavity for receiving the upper row of incisors and a lower receiving cavity for receiving the lower row of incisors.

[0004] The existing technology has the following defects: The above-mentioned vocalization trainer cannot perform real-time detection and feedback on the vocalization quality, and users cannot adjust the vocalization skills and vocalization methods of the muscle groups in a timely manner. During long-term training, incorrect habits may be aggravated or solidified and are difficult to correct, thus affecting the training effect. At the same time, due to the inability to monitor and analyze the vocalization data of users, it is difficult to formulate personalized training plans, and thus it fails to effectively improve specific vocalization problems. Therefore, there is room for improvement. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the present invention provides a multifunctional swallowing training and vocalization assistance exerciser to solve the technical problems that the existing vocalization trainer cannot timely feedback the vocalization training quality of users, and users cannot timely adjust the vocalization skills of the muscle groups, thus affecting the vocalization training effect of users.

[0006] The present invention is realized through the following technical solutions: A multifunctional swallowing training and vocalization assistance exercise device, comprising an arc-shaped plate, a support plate, fixed columns, adjustment straps, a pickup, a display, display lights and a control terminal.

The pickup is used to collect the user's voice signals and display the collected data in the form of volume on the display. The display lights are used to feedback the user's vocalization quality. The control terminal is communicatively connected to the pickup, the display and the display lights. The control terminal includes a data storage module, a voice recognition module and a display light control module. The voice recognition module is used to obtain a pairing result according to the voice signals collected by the pickup and the voice signals pre-stored in the data storage module. The voice recognition module generates a corresponding control instruction according to the pairing result and sends the control instruction to the display light control module. The display light control module is used to control the display color of the display lights according to the control instruction sent by the voice recognition module.

[0007] Preferably, the voice recognition module further includes a voice collection module, a feature extraction module and a feature matching module. The voice collection module is communicatively connected to the pickup and is used to collect and record the voice signals of the pickup. The feature extraction module is used to extract the continuous vocalization features in the user's voice. The feature matching module is used to quickly match the continuous vocalization features of the user with the voice signals in the data storage module, judge the characteristics of the user's continuous vocalization features, identify the user's vocalization position, and display the vocalization position information on the display.

[0008] Preferably, a voice preprocessing module is further arranged on the voice collection module. The voice preprocessing module is used to perform noise reduction processing on the sound signals collected by the pickup to obtain clear voice signals.

[0009] Preferably, the exercise device further includes a mounting seat and a rotating component. The mounting seat is rotatably mounted on the arc-shaped plate through the rotating component. The display and the display lights are arranged on the mounting seat.

[0010] Preferably, the rotating assembly includes a first gear, a second gear, a rack seat, a normally open button, and a normally closed button. The normally open button is electrically connected to the display and the display lamp, and is used to control the simultaneous opening of the display and the display lamp. The normally closed button is electrically connected to the display and the display lamp, and is used to control the simultaneous closing of the display and the display lamp. The first gear is fixed to the mounting seat, the second gear meshes with the first gear and the rack seat respectively, and both ends of the rack seat are electrically connected to the normally open button and the normally closed button.

[0011] Preferably, three vibration modules are further provided on the arc-shaped plate. The vibration modules are communicatively connected to the control terminal. The vibration frequencies of the vibration modules include a low-frequency range of 20 Hz - 200 Hz, a medium-frequency range of 200 Hz - 1000 Hz, and a high-frequency range of 1000 Hz - 5000 Hz. A heating module is further provided on the vibration module. The heating module is communicatively connected to the control terminal, and the heating temperature of the heating module is in the range of 37°C - 45°C.

[0012] Preferably, a piezoelectric sensor is embedded in the support plate and is communicatively connected to the control terminal. Heating modules are also embedded on both sides of the support plate to cover the collarbone areas on both sides and are communicatively connected to the control terminal.

[0013] Preferably, an adjustment strap is further provided on the fixed column. The adjustment strap is fixed to the user's head, and the adjustment strap is made of an elastic band.

[0014] Preferably, the control terminal further includes a restoration module and a voice storage module. The restoration module is used to obtain a reset signal when the display controller obtains a pairing result. The restoration module is also used to record the collected voice signal in the voice storage module and clear the collected voice signal from the voice collection module when the voice collection module generates a control instruction.

[0015] Preferably, an amplifying module is further provided on the voice collection module. The amplifying module is used to amplify the voice signal obtained by the voice collection module to support the feature extraction module.

[0016] The beneficial effects of the present invention are as follows: 1. The exerciser can provide users with real-time feedback on voice volume and voice quality, allowing users to adjust their voice skills in time during training to achieve the best results. At the same time, users can observe the feedback on the display and indicator light to become aware of the strengths and weaknesses of their own voice, helping them pay more attention to changes in voice and thus improve their voice skills. Through targeted voice training, users can better mobilize relevant muscle groups and improve swallowing and voice production. Continuous training will strengthen the function of these muscle groups and improve overall voice and swallowing ability. In addition, through convenient training methods and visual feedback, users will feel more confident and supported during voice training, thereby increasing their enthusiasm and effectiveness of training. 2. The feature extraction module can identify the continuous characteristics of the user's voice, such as pitch, volume, and duration, and determine the user's voice location. The feature matching module compares the voice characteristics with the standard voice characteristics in the database to help users understand their current voice location and make effective adjustments. The voice location information is displayed on the monitor in real time, allowing users to intuitively see the syllables and phonemes they have pronounced, enhancing their cognition and helping them find the correct voice location as soon as possible. 3. The piezoelectric sensor monitors the range of thoracic movement in real time. When thoracic breathing is dominant (inspiration accounts for >60%), the linked heating module applies targeted thermal stimulation of 40°C to 42°C to the subclavian area, activating the phrenic nerve reflex to enhance the depth of diaphragmatic contraction and guiding the user to switch to abdominal breathing mode. This mode improves the quality of vocal cord closure by stabilizing airflow output, reduces breath noise during phonation, and improves training efficiency. In addition, the coordinated optimization of the breathing-swallowing rhythm can reduce the risk of aspiration caused by respiratory disorders in patients with neurological dysphagia; 4. By setting the rotating component, users can easily adjust the direction of the display and display light as needed, making it easier for users to observe the display and display light. When not in use, the mounting base can be rotated until it is parallel to the curved plate, significantly reducing the space occupied by the equipment and avoiding damage when moving or storing the exerciser, thereby extending the effective life of these components in daily use. At the same time, by rotating the angle of the mounting base, the device automatically turns on and off, reducing the complexity of user operations, turning off the display and display light in a timely manner, reducing battery or power consumption, saving costs for users and extending the service life of the equipment.

[0028] To further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following will, with reference to the drawings and preferred embodiments, elaborate in detail on the specific implementation manners, structures, features, and their effects according to the present invention.

[0029] Please refer to Figures 1-7, a multifunctional swallowing training and voice - assisting exercise device, including an arc - shaped plate 1, fixed columns 2, an adjustment belt 6, a pick - up microphone 3, a display 4, display lights 5 and a control terminal. The arc - shaped plate 1 is fixed at the position of the user's lower jaw, and a support plate 11 is fixed at the user's chest. The fixed columns 2 are arranged between the bottoms of both sides of the arc - shaped plate 1 and the tops of both sides of the support plate 11. An elastic component is built in the fixed columns 2. Both ends of the adjustment belt 6 are installed on the fixed columns 2 and fixed at the user's back neck. The pick - up microphone 3 is used to collect the user's voice signal and display the collected data in the form of volume on the display 4. The display lights 5 are used to feedback the user's voice - sounding quality. The control terminal is communicatively connected to the pick - up microphone 3, the display 4 and the display lights 5. The control terminal includes a data storage module, a voice recognition module and a display - light 5 control module. The voice recognition module is used to obtain a pairing result according to the voice signal collected by the pick - up microphone 3 and the voice signal pre - stored in the data storage module. The voice recognition module generates a corresponding control instruction according to the pairing result and sends the control instruction to the display - light 5 control module. The display - light 5 control module is used to control the display color of the display lights 5 according to the control instruction sent by the voice recognition module.

[0030] The working principle of the exercise device in this application is as follows: The arc - shaped plate 1 is fixed at the position of the user's lower jaw, and the support plate 11 is fixed at the user's chest to support the chest pressure. The fixed columns 2 are arranged between the bottoms of both sides of the arc - shaped plate 1 and the tops of both sides of the support plate 11. An elastic component is built in the fixed columns 2 to ensure the stability and comfort of the device during use. The fixed columns 2 elastically connect the arc - shaped plate 1 and the support plate 11 through the built - in elastic component, ensuring that the device is stably fixed to the user's lower jaw and chest, and at the same time dispersing the force, playing a buffering role for the subsequent user's breathing - voice - sounding - swallowing training. At the same time, both ends of the adjustment belt 6 are installed on the fixed columns 2 and used to fix the user's back neck, thereby preventing the movement of the device during the voice - sounding and swallowing training and ensuring the effectiveness during the exercise. The pick - up microphone 3 is responsible for real - time collection of the user's voice signal. The voice signal is converted into a digital signal and processed in the control terminal. The data storage module is used to store a preset voice model. The voice recognition module compares the voice signal collected by the pick - up microphone 3 with the preset voice signal stored in the data module to identify the user's voice - sounding situation. The display - light 5 control module generates a corresponding control instruction according to the result of the voice recognition and controls the color change of the display lights 5. The display 4 displays the user's voice - sounding volume in real time to help the user understand their own voice - sounding intensity. The display lights 5 are used to feedback the user's voice - sounding quality, indicating different voice - sounding effects through different colors. For example, a red light is used to indicate poor voice - sounding quality, a yellow light is used to indicate general voice - sounding quality, and a green light is used to indicate good voice - sounding quality.

[0031] This exerciser can provide users with real-time feedback on voice volume and voice quality, enabling users to adjust their vocalization skills in a timely manner during training to achieve the best results. At the same time, users can be aware of the advantages and disadvantages of their own vocalizations by observing the feedback from the display 4 and the display lights 5, helping them pay more attention to the changes in vocalization, thereby improving their vocalization skills. Through targeted voice training, users can better mobilize relevant muscle groups and improve their swallowing and vocalization abilities. Continuous training will strengthen the functions of these muscle groups and improve the overall voice and swallowing abilities. Through voice recognition and data analysis, personalized training programs or adjustment suggestions can be provided for users to make the training more efficient. In addition, through convenient training methods and visual feedback, users will feel more confident and supported during vocalization training, thereby enhancing their training enthusiasm and effectiveness.

[0032] Please refer to Figure 6 and Figure 7 , in order to help users understand their current vocalization positions and then make effective adjustments to the vocalization muscle groups. Based on this, in one embodiment, the voice recognition module further includes a voice acquisition module, a feature extraction module, and a feature matching module. The voice acquisition module is communicatively connected to the pickup 3 and is used to collect and record the voice signals of the pickup 3. The feature extraction module is used to extract the continuous vocalization features in the user's voice. The feature matching module is used to quickly match the continuous vocalization features of the user with the voice signals in the data storage module, judge the characteristics of the user's continuous vocalization features, identify the user's vocalization position, and display the vocalization position information on the display 4. The feature extraction module can identify the continuous features of the user's vocalization, such as pitch, volume, and duration, and judge the user's vocalization position. For example, the vocalization positions in Mandarin can be divided into bilabial sounds, labiodental sounds, alveolar sounds, apical sounds, retroflex sounds, palatal sounds, and velar sounds. And through the feature matching module, the vocalization features are compared with the standard vocalization features in the database to help users understand their current vocalization positions and then make effective adjustments, and display the vocalization position information on the display 4 in real time. Users can intuitively see the syllables and phonemes they emit, enhancing their cognition and helping them quickly find the correct vocalization position. If there are inaccurate pronunciations, users can correct them immediately. Through clear vocalization position information and feedback, users will feel more in control during training, thereby enhancing their confidence in pronunciation.

[0033] Please refer to Figure 6 and Figure 7, in many actual application scenarios (such as outdoor or noisy environments), the pickup 3 not only captures the target sound but is also affected by the surrounding background noise. Based on this, in one embodiment, a voice preprocessing module is further provided on the voice acquisition module. The voice preprocessing module is used to perform noise reduction processing on the sound signal collected by the pickup 3 to obtain a clear voice signal. By filtering or reducing non-target sounds, the noise reduction processing can significantly improve the clarity of the signal, ensuring that the system obtains the clear voice signal of the user. By reducing the background noise, the system can more clearly identify the vocal characteristics of the user. Such signal enhancement will be crucial for subsequent feature extraction and matching analysis; the clear voice signal can reduce misidentification cases caused by noise interference. After noise reduction, it is easier for the system to extract accurate vocal characteristics, thereby improving the performance of the feature matching module and ensuring that the system can more accurately determine the vocal position and pronunciation characteristics of the user. In the training stage of the system, using the noise-reduced voice data can make the model more stable and accurate, reducing the deviation during the training process.

[0034] Please refer to Figure 4 and Figure 5 , based on this, in one embodiment, the exerciser further includes a mounting base 7 and a rotating assembly 8. The mounting base 7 is rotatably mounted on the arc plate 1 through the rotating assembly 8. The display 4 and the display lamp 5 are arranged on the mounting base 7. When in use, rotate the mounting base 7 to be perpendicular to the arc plate 1. Through the rotating assembly 8, the user can easily adjust the directions of the display 4 and the display lamp 5 as needed, facilitating the user to observe the display 4 and the display lamp 5. When not in use, rotate the mounting base 7 to be parallel to the arc plate 1, significantly reducing the occupied space of the device, which is suitable for home use or use in environments such as rehabilitation centers and hospitals. When the display 4 and the display lamp 5 are placed parallel to the arc plate 1, they are not directly exposed to potential collisions or external forces, greatly reducing the risk of scratches, impacts, or other forms of damage, avoiding damage during the movement or storage of the exerciser, and thus extending the effective life of these components in daily use.

[0035] Please refer to Figure 4 and Figure 5, in order to enable the device to be turned off in time when not in use and reduce the consumption of the battery or power supply. Based on this, in one embodiment, the rotating assembly 8 includes a first gear 81, a second gear 82, a rack seat 83, a normally open button 84 and a normally closed button 85. The normally open button 84 is electrically connected to the display 4 and the display lamp 5, and the normally open button 84 is used to control the simultaneous opening of the display 4 and the display lamp 5. The normally closed button 85 is electrically connected to the display 4 and the display lamp 5, and the normally closed button 85 is used to control the simultaneous closing of the display 4 and the display lamp 5. The first gear 81 is fixed to the mounting seat 7, the second gear 82 meshes with the first gear 81 and the rack seat 83 respectively, and both ends of the rack seat 83 are electrically connected to the normally open button 84 and the normally closed button 85 respectively. When the mounting seat 7 rotates to be perpendicular to the arc plate 1, the first gear 81 drives the second gear 82 to rotate, and the second gear 82 drives the rack seat 83 to move, so that one end of the second rack seat 83 is electrically connected to the normally open button 84, realizing the automatic opening of the display 4 and the display lamp 5; when the mounting seat 7 rotates to be parallel to the arc plate 1, the first gear 81 drives the second gear 82 to rotate in the reverse direction, and the second gear 82 drives the rack seat 83 to move in the reverse direction, so that the other end of the rack seat 83 is electrically connected to the normally closed button 85, realizing the automatic closing of the display 4 and the display lamp 5. When the user uses the exerciser, there is no need to manually turn on or off the display 4 and the display lamp 5. By rotating the angle of the mounting seat 7, the device automatically completes the switching, reducing the operation complexity of the user; the automatic control of the display 4 and the display lamp 5 enables the device to be turned off in time when not in use, reducing the consumption of the battery or power supply, saving costs for the user and prolonging the service life of the device.

[0036] Please refer to Figure 1 and Figure 3, in order to alleviate the muscle fatigue that may occur during the training of users according to the vocal part defects of different users. Based on this, in one embodiment, a vibration module 9 is further provided on the arc-shaped plate 1. There are three groups of vibration modules 9, and the vibration module 9 is communicatively connected to the control terminal. The vibration frequencies of the vibration module 9 include a low-frequency range of 20 Hz - 200 Hz, a medium-frequency range of 200 Hz - 1000 Hz, and a high-frequency range of 1000 Hz - 5000 Hz. The frequency division (low-frequency, medium-frequency, high-frequency) of the vibration module 9 can be targeted at different training needs. For example, low-frequency vibration may be more suitable for helping to activate deep muscles, while high-frequency vibration helps to enhance the sensitivity and reaction speed of muscles. By adjusting the frequency, users can obtain targeted training stimuli, which is crucial for improving the vocal effect; the vibration module 9 is communicatively connected to the control terminal, and according to the vocal part defects of different users, the vibration frequency of the vibration module 9 can be flexibly adjusted to make the training more personalized; appropriate vibration can promote local blood circulation, which is actively helpful for muscle relaxation and metabolism. For users undergoing vocal or swallowing training, good blood circulation helps to improve the state of the laryngeal and oral muscles, thereby enhancing the training effect. Through vibration stimulation, it helps to alleviate the muscle fatigue that may occur during the training of users.

[0037] Please refer to Figure 1 and Figure 3 , in order to enhance the muscle recovery ability and reduce the fatigue after training. Based on this, in one embodiment, a heating module 10 is further provided on the vibration module 9. The heating module 10 is communicatively connected to the control terminal, and the heating temperature of the heating module 10 is in the range of 37°C - 45°C. Appropriate heat can help users relax the muscles around the larynx and mouth, reduce tension, and help users reduce the vocal difficulties caused by tension during vocal training and improve the voice quality; heating can improve the flexibility of muscles and soft tissues, reduce the movement restrictions caused by muscle tightness, and heating can effectively promote local blood flow and enhance the supply of oxygen and nutrients; the increase in heat helps to promote the metabolism of local tissues, thereby enhancing the muscle recovery ability and reducing the fatigue after training, which is especially suitable for users who need a large amount of training; moderate temperature helps to enhance the sensitivity of the sensory nerves in the larynx and mouth, enabling users to better perceive the subtle changes that occur during vocalization or swallowing. Please refer to Figure 1 and Figure 4, in order to adapt to users with different head shapes and sizes and ensure the best wearing experience, based on this, in one embodiment, an adjustment strap 6 is further provided on the fixing post 2. The adjustment strap 6 is fixed at the back of the user's neck, and the adjustment strap 6 is made of an elastic strap. The adjustment strap 6 can ensure the fixation of the arc plate 1 at the position of the user's lower jaw, avoiding the decline of the vocalization and swallowing training effect caused by movement or loosening during the training process; when performing swallowing and vocalization exercises, the user may have various head or lower jaw movements, and the design of the adjustment strap 6 can ensure that the device still maintains a stable position during these dynamic processes, thus ensuring the continuity and effect of the training; the elastic design of the adjustment strap 6 enables it to adapt to users with different head shapes and sizes. When the user uses the device, they can adjust the tightness of the adjustment strap 6 according to their own comfort and training needs to ensure the best wearing experience; the adjustment strap 6 can be adjusted to a comfortable position, avoiding any discomfort caused by being too tight or too loose. A comfortable wearing experience is crucial in vocalization and swallowing training, as discomfort may cause the user to be distracted or affect their performance.

[0038] Please refer to Figure 1 and Figure 4 , in order to achieve the optimization of breathing-vocalization coordination and improve vocalization efficiency, based on this, in one embodiment, a piezoelectric sensor 12 and a heating module 10 are further embedded in the support plate 11. The piezoelectric sensor 12 covers the midline of the sternum to the edges of the ribs on both sides and is communicatively connected to the control terminal. The heating module 10 covers the areas of both collarbones and is communicatively connected to the control terminal. The piezoelectric sensor 12 is used to detect the amplitude of thoracic expansion and the respiratory rhythm. When it detects that thoracic breathing is dominant (inspiration ratio > 60%), the heating module 10 is activated through the control terminal to heat the user's collarbone area to 40 - 42 °C. Through thermal stimulation, the phrenic nerve reflex is activated, prompting the user to instinctively adjust to the diaphragmatic breathing pattern with the diaphragm sinking, breaking the inertia of thoracic breathing. When it detects that diaphragmatic breathing is dominant (inspiration ratio ≤ 50%), the heating module 10 is turned off through the control terminal. The user can adjust their breathing through thermal stimulation feedback without having to learn complex interaction logics, which is convenient for the user to operate; by prompting the user to adopt the diaphragmatic breathing pattern, the coordination efficiency of breathing and vocalization can be significantly improved: Diaphragmatic breathing is dominated by the active contraction and sinking of the diaphragm, significantly increasing the pulmonary ventilation volume, providing stable airflow support for vocal cord vibration, reducing the breathy noise during vocalization and enhancing the control accuracy of sound intensity. At the same time, the regular movement of the diaphragm can coordinate the linkage of the laryngeal muscles and swallowing movements, reducing the risk of aspiration caused by respiratory disorders during swallowing, especially suitable for patients with neurological swallowing disorders. In addition, the phrenic nerve reflex triggered by targeted heating of the collarbone area helps the user quickly establish the habit of diaphragmatic breathing and shorten the rehabilitation period.

[0039] Please refer to Figure 6, in order to record the collected voice signals and clear the old data in a timely manner. Based on this, in one embodiment, the control terminal further includes a restoration module and a voice storage module. The restoration module is used to obtain a reset signal when the display 4 controller obtains a pairing result. The restoration module is also used to record the collected voice signals in the voice storage module and clear the collected voice signals from the voice collection module after the voice collection module generates a control instruction. After receiving the reset signal from the display 4 controller, the restoration module can restore the system or device to the initial state, avoiding interference caused by the residue of historical data or operation states; before each training starts, the restoration module ensures that all parameters and settings are in appropriate initial settings, ensuring that users can obtain consistent and predictable effects in each training; when the voice collection module generates a new control instruction, the restoration module will clear the previously collected voice signals from the voice collection module. By clearing the old data in a timely manner, the restoration module helps to free up storage space and processing power, enabling the device to prepare for the next data collection more quickly and improving operation efficiency; the voice storage module can record the collected voice signals to form a file, providing basic data for subsequent training comparison and effect evaluation. Users and therapists can understand the progress and rehabilitation status of the user by comparing the voice data at different time nodes. The stored historical voice data can help users and therapists formulate more targeted training plans, such as conducting more concentrated and effective training for specific pronunciation problems.

[0040] Please refer to Figure 6 , in order to ensure that the collected voice signals are clearer, purer, and accurately extract various features in the voice signals. Based on this, in one embodiment, a sound amplification module is further provided on the voice collection module. The sound amplification module is used to amplify the voice signals obtained by the voice collection module and provide support for the feature extraction module. When conducting voice training, there may be noise in the surrounding environment. The sound amplification module can effectively enhance the user's voice signals, suppress background noise, and ensure that the collected voice signals are clearer and purer. By amplifying the obtained signals, the sound amplification module makes the subsequent feature extraction more reliable, helping to avoid incorrect recognition and inaccurate analysis caused by weak signals in the subsequent processing process; the high-definition signals generated by the sound amplification module provide high-quality input data for the feature extraction module, enabling the latter to accurately extract various features in the voice signals, such as pitch, frequency, volume, and pronunciation. After the signals are strengthened, the feature extraction module can process the input data more quickly, reducing the occupation of computing resources and improving the working efficiency of the system.
