Technical Field

[0001] This utility model relates to the field of attention training technology, and in particular to an attention training device based on electroencephalogram (EEG) signals. Background Technology

[0002] Bluetooth headphones, as wireless audio devices, are widely used in communication, entertainment, and other fields. While some Bluetooth headphones possess attention signal monitoring capabilities, their application in focus training and EEG signal interaction remains relatively limited, despite increasing demand. Existing attention training products lack real-time interaction with the user's physiological state, resulting in poor training engagement and ultimately, suboptimal training outcomes.

[0003] Therefore, there is an urgent need for an attention training product that combines EEG monitoring with physical interaction to enhance the fun and effectiveness of users' attention training, especially suitable for children or adults who need attention training. Utility Model Content

[0004] The purpose of this invention is to provide an attention training device based on electroencephalogram (EEG) signals, which can enhance the fun and effectiveness of users' concentration training, thereby improving the effect of attention training.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An attention training device based on electroencephalogram (EEG) signals, comprising:

[0007] The earphone body includes an ear inlet that can fit and snap into the user's ear canal.

[0008] A clamping member, the clamping member including a fitting portion, the fitting portion being able to fit onto the back of a user's ear;

[0009] An ear loop is provided, with its two ends connected to the headphone body and the clamping member, respectively; the ear loop is flexible and deformable to form a clamping groove that can clamp the user's ear.

[0010] A monitoring device is disposed on the earphone body and the clamping member to monitor the user's attention level;

[0016] Preferably, the monitoring device further includes a data processing module, which is disposed on the clamping member, and the in-ear monitoring sensor and the electrode channel are both electrically connected to the data processing module.

[0017] Preferably, the monitoring device further includes a monitoring and control module, which is electrically connected to the in-ear monitoring sensor, the electrode channel, and the data processing module.

[0018] Preferably, the attention adjustment device includes:

[0019] A mechanical barrier structure is rotatably mounted on the module base and located within the accommodating space;

[0020] It is freely positioned within the accommodating space in conjunction with the rolling element;

[0021] The attention monitoring and control module can receive attention level data monitored by the monitoring device, and drive the mechanical obstacle structure to rotate within the accommodating space based on the attention level data, so that the mating rolling element can fall freely.

[0022] Preferably, the module base is provided with several ring-shaped lights, which are connected to the attention monitoring and control module. The attention monitoring and control module can control the ring lights to light up level by level according to attention level data.

[0026] Preferably, the transparent outer shell has notches on both opposite sides, allowing the mating rolling element to enter and exit the accommodating space through the notches;

[0027] When two training devices are arranged one above the other, the notches of the two adjacent training devices are arranged vertically and vertically respectively.

[0032] This invention achieves stable wearing through a triple structure: the earphone body's in-ear portion fits into the ear canal, the clip attaches to the back of the ear, and a flexible ear hook forms a clip groove. This structure lays the foundation for continuous collection of attention signals. By placing the monitoring device in two positions—one on the earphone body and the other on the clip—it can accurately collect head attention signals, precisely monitor attention levels, and synchronously drive the training device to make dynamically matched response actions. This not only solves the problems of lack of interaction and ambiguous judgment in existing products but also enhances the targeting and enjoyment of training through real-time feedback, ultimately achieving effective training goals.

[0047] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0048] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0049] In this application, the term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of only one centrifugal vortex magnetic pump, the simultaneous existence of one centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, or the existence of only one centrifugal vortex magnetic pump. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0050] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0051] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0052] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0053] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0054] Based on the foregoing, while some Bluetooth headphones possess attention signal monitoring capabilities, their application in focus training and EEG signal interaction remains relatively limited. Existing attention training products lack real-time interaction with the user's physiological state, leaving room for improvement in both training enjoyment and effectiveness.

[0055] To resolve the above issues, please refer to [link / reference]. Figures 1 to 4 This embodiment provides an attention training device based on electroencephalogram (EEG) signals, which includes an earphone body 1, a clamp 2, an ear loop 3, a monitoring device, and a training device.

[0056] The earphone body 1 includes an ear inlet 11 that fits and snaps into the user's ear canal. The clamping member 2 includes a fitting part 21 that fits onto the back of the user's ear. The ear hook 3 is connected to both ends of the earphone body 1 and the clamping member 2; the ear hook 3 is flexible and deformable to form a clamping groove that holds the user's ear. A monitoring device is mounted on the earphone body 1 and the clamping member 2 to monitor the user's attention level. The training device includes a snap-fit ​​modular base 6 and a transparent shell 7, with a receiving space 9 formed between the modular base 6 and the transparent shell 7. An attention adjustment device 5 is disposed within the receiving space 9, and the attention adjustment device 5 operates in accordance with the attention level monitored by the monitoring device to train the user's attention.

[0057] This design, with its triple structure of the earphone body 1's in-ear portion 11 fitting into the ear canal, the clip 2's contact portion 21 attaching to the back of the ear, and the flexible ear hook 3 forming a clamping groove, ensures stable wearing and lays the foundation for continuous collection of attention signals. The dual-position layout of the monitoring device on both the earphone body 1 and the clip 2 allows for accurate collection of head attention signals and precise monitoring of attention levels. This synchronously drives the training device to make dynamically matched response actions, solving the problems of lack of interaction and ambiguous judgment in existing products. Furthermore, real-time feedback enhances the targeting and enjoyment of training, ultimately achieving effective training goals.

[0058] In addition, the flexible ear hook 3, in conjunction with the matching earpiece 11, can adapt to the differences in ear shape and ear canal between children and adults, achieving multi-person adaptation and meeting the needs of core users. Specifically, both ends of the flexible ear hook 3 are provided with telescopic connecting parts. The telescopic connecting part at one end is integrally connected to the outer wall of the earpiece 11 of the headphone body 1. This connecting part is composed of two nested sleeves, and a micro elastic component (such as a micro compression spring, elastic silicone pillar, etc.) is built into the gap between the two sleeves to form a telescopic structure that can move slightly. The sleeve can slightly extend and retract radially along the earpiece 11. The telescopic connecting part at the other end is fixedly connected to the end of the clamp 2. It also adopts a flexible sleeve design that can be stretched axially. The elastic fibers inside the sleeve can maintain a stable shape after extension and retraction without compromising the flexibility of the ear hook 3 itself. This design allows for several advantages. For children, the retractable connecting parts at both ends of the ear hook 3 shorten the overall span, making the in-ear portion 11 fit more snugly into the child's narrow ear canal. Simultaneously, the clamping groove formed by the hook more tightly envelops the child's small ear. For adults, the retractable connecting parts at both ends are stretched, increasing the span of the ear hook 3 to accommodate wider adult earlobes. The radial position of the in-ear portion 11 is also fine-tuned to ensure a stable fit with the adult ear canal. This balances comfort and stability for different user groups, effectively covering both children and adults, and meeting diverse usage scenarios.

[0059] Specifically, the ear hook 3 is detachably connected to the earphone body 1 via a connecting component 4; and / or the ear hook 3 is detachably connected to the clip 2 via a connecting component 4. This design allows for flexible adaptation to different users' ear sizes. Whether it's a child's small ear or an adult's larger ear, the ear hook 3 can be replaced with the corresponding size, ensuring a snug fit in the clip slot and solving the problem that fixed ear hooks 3 cannot accommodate the comfort of multiple users. Furthermore, if the ear hook 3 becomes worn, dirty, or damaged, it can be disassembled and replaced separately without replacing the entire earphone or clip 2, reducing maintenance costs and facilitating the cleaning of dirt from the gaps in the ear hook 3.

[0060] In this embodiment, the connecting component 4 includes a plug 41 and a socket 42 that are adapted for insertion. The plug 41 is disposed on one of the earphone body 1 and the ear hook 3, and the socket 42 is disposed on the other of the earphone body 1 and the ear hook 3. In this embodiment, the socket 42 is disposed on the ear hook 3, and the plug 41 is disposed on the earphone body 1. It can be understood that connecting the earphone body 1 and the ear hook 3 by plugging is simple in structure and easy to operate. In addition, when the two ends of the ear hook 3 are connected to the earphone body 1 and the clamp 2 respectively through the connecting component 4, it is also necessary to ensure that the earphone body 1 and the clamp 2 can be electrically connected through the ear hook 3 so that the clamp 2 can control the working state of the earphone body 1 through the ear hook 3.

[0061] In addition, the specific components of the clamp 2 and the headphone body 1 are selected according to actual usage requirements. For example, in addition to the components for playing and receiving sound, the headphone body 1 can also be equipped with components for active noise cancellation. The clamp 2 is correspondingly equipped with components for controlling the working state of the above three components. No specific requirements or restrictions are imposed on this.

[0062] To further enhance the comfort of wearing the headphones, a flexible pad is detachably provided on the fitting part 21. Additionally, after repeated use, the flexible pad may become dirty or even damaged. Therefore, to ensure users always have a good user experience, the flexible pad is detachably mounted on the fitting part 21, allowing users to easily replace dirty or damaged pads. It should be noted that the flexible pad is preferably made of skin-friendly rubber materials, such as natural rubber, styrene-butadiene rubber, or polyurethane. It should also be noted that the flexible pad can be detachably mounted on the fitting part 21 in any manner, such as by fastening or adhesive.

[0063] It should be noted that the ear pendant 3 can be made of any existing flexible material, such as elastic metal, shape memory alloy, flexible rubber, flexible plastic, etc. This embodiment does not make specific requirements or limitations on this.

[0064] Specifically, the monitoring device includes an in-ear monitoring sensor 12 and an electrode channel 22. The in-ear monitoring sensor 12 is disposed inside the earphone body 1 and is used to acquire the user's electroencephalogram (EEG) signals. The electrode channel 22 is disposed on the clamping member 2 and away from the in-ear monitoring sensor 12, and the electrode channel 22 is provided with a reference signal. The user's attention level data is obtained through the EEG signals and the reference signal.

[0065] Among them, the in-ear monitoring sensor 12 serves as the monitoring electrode, and its core function is to collect the user's electroencephalogram (EEG) signals. The electrode channel 22 serves as the reference electrode, and its core function is to provide a stable reference signal. By performing differential calculation between the EEG signals collected by the monitoring electrode and the reference signal of the reference electrode, different levels of user attention signals can be obtained.

[0066] In this embodiment, the placement of the in-ear monitoring sensor 12 away from the electrode channel 22 effectively ensures signal processing performance. If the two are too close, the reference electrode is prone to coupling with the target EEG signal collected by the monitoring electrode, causing the reference signal to lose its benchmark nature and the differential operation to fail to effectively filter noise. By placing them far apart, it ensures that the reference electrode collects a stable benchmark signal that is not significantly affected by the target EEG signal, while also preventing the monitoring electrode from being interfered with by the surrounding environment of the reference electrode. This further guarantees the purity of the target EEG signal and the reliability of the reference signal. Ultimately, through their synergistic effect, the judgment of attention level data becomes more accurate. This addresses the core obstacle of the limited EEG signal interaction application in existing products from the signal processing perspective, providing solid data support for the real-time interaction of the training device. In addition, the monitoring device also includes a monitoring and control module, which is electrically connected to the in-ear monitoring sensor 12, the electrode channel 22, and the data processing module.

[0067] In this embodiment, the attention adjustment device 5 includes a mechanical obstacle structure 51, a cooperating rolling element 513, and an attention monitoring and control module. The mechanical obstacle structure 51 is rotatably mounted on the module base 6 and located within the accommodating space 9. The cooperating rolling element 513 is freely disposed within the accommodating space 9. The attention monitoring and control module can receive attention level data monitored by the monitoring device and drive the mechanical obstacle structure 51 to rotate within the accommodating space 9 based on the attention level data, so that the cooperating rolling element 513 falls freely. Through the rotation of the mechanical obstacle structure 51 and the falling of the cooperating rolling element 513 within the accommodating space 9, the user can intuitively follow the movement of the cooperating rolling element 513 to perform focused attention training. When the attention level increases from a lower level, the obstacle rotates, causing the rolling element to fall, providing dynamic and visual feedback, thereby further improving the user's focus during attention training, and gradually increasing the attention level, ultimately achieving the purpose of attention training.

[0068] Specifically, the module base 6 uses a silicone shell 61 with a silicone suction cup 62 at the bottom, allowing the module base 6 to be vertically attached to a smooth surface, such as a wall. This allows the mating rolling element 513 inside to be placed on the mechanical obstacle structure 51 under gravity, and the mating rolling element 513 to fall freely downwards when the mechanical obstacle structure 51 rotates. It is easy to operate, allowing for convenient removal and placement, making it ideal for users who need attention training.

[0069] In addition, the upper surface of the module base 6 is equipped with three rings of lights 63 to display the user's attention level. The lights can be lit up in stages. When all the lights are lit, it indicates that the attention signal has reached the control standard. This intuitive light feedback method allows users to understand their attention level in real time and clearly without having to look at the data panel or operate the device. It also allows them to quickly determine whether the conditions for subsequent function activation or task execution are met, which significantly reduces the cost of status recognition and improves interaction efficiency and user experience.

[0070] refer to Figure 2 Specifically, the mechanical obstacle structure 51 includes a rotating shaft 514 and a stop plate 511. The rotating shaft 514 is rotatably mounted on the module base 6. The stop plate 511 is fixedly connected to the rotating shaft 514 and, in conjunction with the rolling element 513, can freely fall from the upper space 91 to the lower space 92 of the stop plate 511 when it rotates. With this configuration, after the attention monitoring and control module receives the user's attention level data from the monitoring device, it will drive the rotating shaft 514 in the mechanical obstacle structure 51 to rotate on the module base 6. Since the stop plate 511 is fixedly connected to the rotating shaft 514, when the rotating shaft 514 rotates, it will synchronously drive the stop plate 511 to rotate, causing the cooperating rolling element 513, which was originally supported or limited by the stop plate 511 in its upper space 91, to lose its supporting force or limiting function, and then fall freely from the upper space 91 of the stop plate 511 to the lower space 92 of the stop plate 511, completing a physical action feedback that is linked to the user's attention level.

[0071] On the one hand, the mechanical obstacle structure 51 is simple in composition, requiring only the rotation drive of the rotating shaft 514 and the synchronous movement of the stop plate 511. It does not require complex transmission components, which reduces production and maintenance costs and the probability of failure during long-term use, making it suitable for the high-frequency use requirements of attention training devices. On the other hand, the rotation of the stop plate 511 and the falling of the rolling part 513 are intuitive and have a clear cause-and-effect relationship, which users can clearly perceive. Especially for children, the concrete mechanical action is easier to understand than abstract data, further enhancing the interactivity and fun of training. At the same time, the rotating shaft 514 can adjust the rotation angle and speed according to the attention level. For example, the more focused the attention, the faster the door plate rotates and the faster the rolling part falls, realizing personalized feedback and improving the training effect.

[0072] refer to Figure 3In another feasible embodiment, the mechanical barrier structure 51 includes a fixed stop 512 disposed on the module base 6. The fixed stop 512 is provided with a guide channel. The guide channel is separated into an upper space 91 and a lower space 92 by a partition. The upper space 91 and the lower space 92 are connected by a passage that allows only the mating rolling element 513 to pass through, so that the mating rolling element 513 can fall freely from the upper space 91 of the fixed stop 512 to the lower space 92 of the fixed stop 512.

[0073] In particular, combining the core functions of the stop panel 511 supporting the rolling element 513 and rotating to trigger the fall, it takes into account user preferences and adaptability. It can be designed in a variety of shapes, and can also add fun figurative shapes suitable for children (such as rabbit ear shapes or bear paw shapes with animal outlines), which have stronger visual appeal when rotating; as well as natural element shapes such as leaf shapes and cloud shapes, further catering to children's preferences.

[0074] Specifically, the mechanical obstacle structure 51 can retract and rotate itself through a motor and electromagnet based on real-time feedback from EEG signals, thereby forming a channel for the cooperating rolling element 513 to pass through, realizing interactive attention control. When the monitoring device outputs attention level data converted from EEG signals, the driving component of the mechanical obstacle structure 51 receives the signal and triggers an action, opening the originally blocked path and forming a channel for the cooperating rolling element 513 to pass through, so that the passage status is linked with the user's attention status in real time.

[0075] In particular, the training device uses a transparent shell 7, making the state of the attention adjustment device 5 as it operates according to the attention level visible, forming a real-time interactive closed loop. Compared with the single feedback of software or simple hardware, this significantly enhances the fun and effectiveness of training. At the same time, the device integrates headphone audio function, monitoring function, and training function into one, enhancing the product's functionality and improving ease of use.

[0076] To enhance usability, the modular base 6 and the transparent shell 7 are detachably connected via a connecting structure 8. Users can quickly disassemble or assemble the modular base 6 and the transparent shell 7 as needed, facilitating the cleaning and replacement of the mechanical barrier structure 51 and the cooperating rolling element 513 within the accommodating space 9, avoiding the tedious process of complete disassembly. Furthermore, notches 71 are provided on both opposite sides of the transparent shell 7, allowing the cooperating rolling element 513 to enter and exit the accommodating space 9 through the notches 71. When two training devices are arranged vertically, the notches 71 of adjacent training devices are aligned vertically, allowing the cooperating rolling element 513 of the upper training device to fall out through its notch 71 and enter the accommodating space 9 of the lower training device through its notch 71.

[0077] As shown above, notches 71 are provided on both sides of the transparent shell 7, allowing the scrolling component 513 to enter and exit the receiving space 9. When multiple training devices are arranged vertically, the notches 71 correspond, allowing the scrolling component 513 to be passed between devices, achieving continuity in the training process. Users need to maintain continuous attention to allow the scrolling component 513 to pass through multiple devices in sequence, avoiding the limitations of single-time feedback from a single device and enhancing the continuous training effect of concentration. In addition, the training difficulty and duration can be adjusted by increasing or decreasing the number of devices to suit different needs such as basic training for children or advanced training for adults. Furthermore, the dynamic process of the scrolling component being passed between devices enhances visual coherence and the sense of interactive hierarchy, which is more attractive than the independent feedback of a single device, and can encourage users to actively maintain their attention to complete the continuous process, further enhancing the fun and participation of the training.

[0078] When a single device operates independently, it provides drop feedback within the accommodating space 9 in conjunction with the rolling element 513. Users can activate it at any time without complex assembly, making it particularly suitable for children to establish a cognitive association between attention and physical feedback when they first encounter it. At the same time, the simple process of using a single device lowers the initial barrier to entry, helping users to quickly understand it and laying the foundation for subsequent advanced training.

[0079] When using the two training devices, they are connected vertically. The rolling element 513 falls from the upper device to the lower device, triggering an obstacle structure on the lower device to initiate a new round of interaction. Users must maintain their attention while the rolling element 513 falls from the upper device to ensure the lower device successfully receives the feedback and initiates the next round, avoiding distraction that could cause the rolling element 513 to get stuck at the gap 71. Furthermore, the difficulty of the obstacles on the two devices can be varied, such as the upper device being simpler and the lower device more complex, to achieve progressively challenging training. Alternatively, a two-player mode can be designed, with one person controlling one device, allowing for continuous passing of the rolling element 513 through collaboration, thus enhancing the interactivity and competitiveness of the training.

[0080] refer to Figure 4 When multiple training devices are used, they connect sequentially to form a transmission chain with a rotating component 513. Each device can be equipped with different types of obstacle structures. On the one hand, the rotating component 513 must pass through all devices in sequence, requiring the user to maintain focus for a longer period of time, thus specifically improving attention endurance. On the other hand, the number of devices can be adjusted to increase the challenge and novelty of the training. Furthermore, the combination of multiple devices supports personalized difficulty adjustments, such as three basic devices for children and five complex devices for adults, adapting to the long-term training needs of different users.

[0081] It should be noted that the connecting structure 8 can adopt an existing snap-fit ​​connection structure. Specifically, the edge of the module base 6 is evenly provided with 3-4 elastic protruding snaps 81, and the transparent shell 7 has corresponding slots 82. During assembly, align the module base 6 with the transparent shell 7 and press it down; the snaps 81 will fit into the slots 82 to secure it. During disassembly, the snaps 81 can be easily pried apart without additional tools, making the operation convenient. This facilitates daily disassembly and cleaning while ensuring a stable connection between the module base 6 and the shell during use, preventing it from falling off.

[0082] The attention training device based on EEG signals provided in this embodiment achieves ear canal adaptation and snap-fit ​​through the earphone body 1's in-ear part 11. The clamping part 21 is attached to the back of the ear and has a detachable flexible pad. The ear hook 3 can be replaced with multiple length specifications through the telescopic connecting part and connecting component 4, taking into account the differences in ear canals and auricles of children and adults, and ensuring stable and comfortable wearing. The monitoring device relies on the far-away layout of the in-ear monitoring sensor 12 and electrode channel 22 to accurately collect EEG signals and reference signals, and outputs attention level data after processing by the monitoring and control module. In the training device, the silicone shell 61 and silicone suction cup 62 of the module base 6 ensure safe use and stable placement. The ring light 63 intuitively displays the level of concentration. The notch 71 of the transparent shell 7 cooperates with the upper and lower docking of multiple devices to realize the transmission of the cooperating rolling part 513. The rotating shaft 514 and stop plate 511 of the mechanical obstacle structure 51 rotate dynamically with the attention level, allowing the cooperating rolling part 513 to complete the drop feedback. The buckle 81 and slot 82 of the connecting structure 8 facilitate the disassembly and cleaning of the module base 6 and the transparent shell 7. Overall, it not only solves the problems of existing products lacking physiological interaction, poor adaptability, and insufficient fun, but also achieves the goal of efficient and fun attention training through real-time monitoring, dynamic feedback, multi-group adaptation, and multi-scenario combination.
