Description

Technical Field

[0001] The present invention relates to the technical field of brain wave training earphones, and in particular to an intelligent brain wave training earphone based on alpha waves. Background Art

[0002] Headphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. Headphones can be detached from the media player and connected using a single plug, allowing you to listen to audio without disturbing others. They can also block out ambient sound, making them particularly useful in noisy environments such as recording studios, bars, travel, and sports.

[0003] With the development of modern science and technology, headphones have become more diverse. For example, EEG headphones use dry electrode sensors inside the headphones to identify brain waves and play different music accordingly. EEG is a method of recording brain activity using electrophysiological indicators. When the brain is active, it is formed by the sum of the postsynaptic potentials generated synchronously by a large number of neurons. It records the changes in electrical waves during brain activity and is a comprehensive reflection of the electrophysiological activity of brain nerve cells on the cerebral cortex or scalp surface.

[0004] Patent number CN114025286A discloses a Bluetooth headset that plays alpha wave music. The headset includes an antenna, a Bluetooth module, an MCU, an alpha wave sound source, an audio decoder, an audio power amplifier, and a headphone speaker. The headset generates alpha waves—single-frequency sound waves between 4 and 14 Hz—which, combined with the music played through the headphone speaker, create an alpha wave music sound field. The frequency and amplitude of these alpha waves can be adjusted based on the user's needs, synchronizing the user's alpha brainwaves with the generated alpha waves, achieving beneficial results.

[0005] However, the above-mentioned products directly use alpha wave sound sources to generate alpha wave frequencies, which are then decoded to ultimately enable the human ear to hear alpha wave music. The human brain is fully capable of generating alpha waves under relatively low conditions. Therefore, the device cannot directly collect alpha waves in the human brain, and thus will have a certain impact on the user experience in the final use. Therefore, traditional alpha wave headphones still have defects in actual use.

[0006] Therefore, it is necessary to provide an intelligent brainwave training headset based on alpha waves to solve the above technical problems. Summary of the Invention

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0045] First embodiment:

[0046] The present invention provides an intelligent brain wave training headset based on alpha waves.

[0047] Please combine Figures 1 to 7 , an alpha wave-based intelligent brainwave training headset, comprising a first mounting plate 1, a second mounting plate 2, an adjustment component 5, a sound source 15, a central processing module 16, a brainwave recognition module 17, a music processing module 18 and a frequency modulation module 19;

[0048] The outer ends of the first mounting plate 1 and the second mounting plate 2 are snap-connected with the mounting frame 3, and the outer ends of the first mounting plate 1 and the second mounting plate 2 and located outside the mounting frame 3 are snap-connected with the shield 4;

[0049] The adjustment assembly 5 includes an adjustment gear 51 rotatably connected to the middle position inside the installation frame 3, a knob 52 is fixedly provided at the axis center of the adjustment gear 51 and located on the outside of the installation frame 3, a first arc-shaped rack 54 is meshed and connected inside the installation frame 3 and located on the top of the adjustment gear 51, a curved plate 53 is fixedly provided on the top of the first curved rack 54, a second curved rack 55 is fixedly provided on the lower surface of the curved plate 53 and located on one side of the first curved rack 54, a limiting plate 56 is fixedly provided on the upper surface of the curved plate 53, a mounting sleeve 57 is fixedly provided on the outer wall of the curved plate 53 and located on the same axis center as the adjustment gear 51, a dry electrode sensor 58 is embedded in the mounting sleeve 57, a sliding groove 14 is provided inside the installation frame 3, and a player 13 is mounted on the bottom of both the first mounting plate 1 and the second mounting plate 2;

[0050] Combine Figure 2 and Figure 3 : The user can rotate the knob 52 clockwise to drive the adjustment gear 51 to rotate clockwise. When the adjustment gear 51 rotates, it can engage and control the first arc-shaped rack 54 to rotate clockwise, driving the arc-shaped plate 53 to move clockwise, which can eventually drive the installation sleeve 57 and the internal dry electrode sensor 58 to move to the right.

[0051] Combine Figure 4: When the user rotates the knob 52 counterclockwise, the adjustment gear 51 will also drive the control mounting sleeve 57 and the internal dry electrode sensor 58 to move to the left, and when moving to the left or right, the extreme position is the separation component 6 and the interference gear 73.

[0052] The limiting plate 56 is slidably connected to the inner top of the installation frame 3 , and the cross section of the limiting plate 56 is a “T”-shaped structure.

[0053] The tooth pitch of the first arc-shaped rack 54 is twice the tooth pitch of the second arc-shaped rack 55 , and the cross-section of the dry electrode sensor 58 is a conical structure.

[0054] Combine Figure 6 It can be seen that the installation method of sliding connection between the limiting plate 56 and the inner top of the installation frame 3 can ensure that the entire arc plate 53 can be more stable and smooth during the movement.

[0055] The dry electrode sensor 58, the sound source 15 and the central processing module 16 are electrically connected in parallel, the dry electrode sensor 58, the central processing module 16, the brain wave recognition module 17, the music processing module 18 and the frequency modulation module 19 are electrically connected in series, and the two players 13 and the frequency modulation module 19 are electrically connected in parallel.

[0056] Combine Figure 5 : During use, the mounting frame 3 needs to be worn on the forehead, and then the dry electrode sensor 58 is fitted to the user's brain. At this time, if the user generates alpha waves in a suitable environment, the dry electrode sensor 58 will transmit the collected alpha waves to the central processing module 16 for signal amplification, and then the brain wave recognition module 17 will perform recognition, judgment and analysis. The music processing module 18 will play music suitable for the current situation according to the brain wave signal at that time, and when the music is generated, the frequency modulation module 19 will also perform proportional frequency modulation according to the basic frequency (8 to 13 Hz), and finally achieve the frequency difference between the two ears to play alpha frequency music. If the dry electrode sensor 58 cannot collect the alpha waves of the human brain, the external sound source 15 can stably generate an alpha basic frequency.

[0057] This embodiment: Compared with the traditional design, this design has a range for moving the position of the dry electrode sensor 58 to the left and right, so that the dry electrode sensor 58 is not fixed in one position to collect alpha waves. Therefore, in actual use, the user can adjust the dry electrode sensor 58 to different positions in the human brain to facilitate the collection of the best alpha waves, which can ensure the best user experience. Secondly, the use of collection and external sound source 15 to realize alpha waves can make the function more comprehensive.

[0058] Second embodiment:

[0059] See also Figure 1 、 Figure 4 and Figure 8 , and also includes a separation component 6, which includes a mounting tube 61 fixed to the outer wall of the mounting frame 3, a sliding rod 63 is slidably connected to the inner wall of the mounting frame 3 and located inside the mounting tube 61, and a separation spring 64 is sleeved on the outer wall of the sliding rod 63. A pointed cone 62 is fixed inside the mounting frame 3 and at one end of the sliding rod 63. A positioning frame 9 is fixed to the outer wall of the protective cover 4, and a placement seat 10 is fixed on the upper surface of the positioning frame 9.

[0060] Combine Figure 4 and Figure 8 :Users can Figure 4 On the basis of the extreme position, the mounting sleeve 57 can be moved to the left again. When the mounting sleeve 57 moves to the inclined surface of the pointed cone 62, the slide rod 63 can be controlled to slide in the mounting tube 61 to extend the separation spring 64. Finally, when the pointed cone 62 completely enters the interior of the mounting sleeve 57, the pointed cone 62 resets and controls the dry electrode sensor 58 and the mounting sleeve 57 to separate. In this way, the user can remove the dry electrode sensor 58 and place it on the placement seat 10 for storage during exercise or other working environments.

[0061] In this embodiment, when the mounting sleeve 57 exceeds the limit position on the left side, the pointed cone 62 can pop out to separate the dry electrode sensor 58 inside the mounting sleeve 57. This design allows the user to separate the dry electrode sensor 58 during exercise or other states, thereby preventing the dry electrode sensor 58 from always being in contact with the human brain. Therefore, this design also increases the service life of the dry electrode sensor 58.

[0062] Third embodiment:

[0063] See also Figure 1 、 Figure 9 and Figure 12 The side wall of the second mounting plate 2 is installed with a strap 11, and the interior of the strap 11 is provided with equidistantly distributed positioning holes 12. The outside of the first mounting plate 1 is installed with a fine-tuning component 8, and the fine-tuning component 8 includes a positioning plate 81 fixed on the outer wall of the first mounting plate 1, and an elastic tooth plate 82 is installed on the inner top of the positioning plate 81. Two limiting grooves 84 are provided inside the positioning plate 81, and a slider 83 is slidably connected inside the two limiting grooves 84. A positioning block 85 is fixed on the outer wall of the slider 83, and a positioning spring 87 is installed inside the slider 83. Positioning pins 86 are fixed at both ends of the positioning spring 87.

[0064] The top of the slider 83 is engaged with the bottom of the elastic tooth plate 82 , and the two positioning pins 86 are slidably connected to the slider 83 .

[0065] Combine Figure 1 and Figure 9 : When the user is in the working state of the first embodiment, the dry electrode sensor 58 is in contact with the human brain. At this time, after wearing the mounting frame 3, the user also needs to wrap the strap 11 around the back of the head and then position the positioning hole 12 in the positioning block 85. In order to ensure that the dry electrode sensor 58 can be stably fitted, it can be directly pulled to the farthest positioning hole 12 to ensure that the dry electrode sensor 58 is stably fitted.

[0066] Combine Figure 10 : When in the working state of the second embodiment, it is the normal mode, so the user can temporarily adjust the positioning hole 12 of a feeding gear, and then slide the slider 83 to the right to control the continuous rebound of the elastic tooth plate 82, so that the distance of the positioning block 85 can be controlled to achieve fine-tuning of the positioning block 85 so that the comfort can be optimized.

[0067] Combine Figure 10 and Figure 12 It can be seen that when the slider 83 slides, the positioning pin 86 and the limiting groove 84 that are continuously stressed can stably ensure the smooth sliding of the slider 83 and prevent the slider 83 from loosening toward the inside of the positioning plate 81.

[0068] The outer end of the positioning rod 71 is fixed with a pipe 72, and the inner sliding connection of the pipe 72 is connected to two piston rods 79. The outer walls of the two piston rods 79 are provided with a return spring 710, and the bottom ends of the two piston rods 79 are fixed with an inclined plate 711. The inner rotation of the mounting frame 3 is connected to a resistance gear 73, and a rotating rod 74 is fixed at the axis of the resistance gear 73 and located inside the positioning frame 9. Friction plates 75 are installed on both sides of the rotating rod 74. A cam 76 is fixed at one end of the rotating rod 74 and located inside the positioning frame 9. An air bag 77 is installed on the inner wall of the positioning frame 9 and in the same horizontal direction as the cam 76. A hose 78 is sealed on the outer wall of the air bag 77.

[0069] One end of the hose 78 is sealed and installed with the pipe 72 , and the interference gear 73 and the second arc-shaped rack 55 are adapted to each other.

[0070] Combine Figure 11: When the fine-tuning slider 83 moves to the position of the inclined plate 711, when the user wants to move the second arc-shaped rack 55 to the right, the clockwise rotating second arc-shaped rack 55 can engage and control the interference gear 73 to rotate clockwise. At this time, the interference gear 73 controls the cam 76 clockwise to squeeze the airbag 77 and pressurize the pipe 72 through the hose 78, so that the piston rod 79 will descend to control the inclined plate 711 to descend and interfere with the force-bearing positioning block 85. When the positioning block 85 is subjected to horizontal force, it will control the positioning pin 86 to contract, so that the slider 83 and the elastic tooth plate 82 can be separated to facilitate rapid separation.

[0071] In this embodiment: When the user is in the brain wave working mode and the normal working mode, the user can freely adjust the large span adjustment or fine adjustment between the positioning block 85 and the positioning hole 12. The user can make the adjustment selection according to his or her own comfort and the usage at the time, and rotating the second arc-shaped rack 55 can quickly control the quick separation of the fine-tuned slider 83, which can facilitate the user's easy use.

[0072] Please refer to Figures 1 to 12 The working principle of the intelligent brainwave training headset based on alpha waves provided by the present invention is as follows:

[0073] Step S1: During use, the mounting frame 3 needs to be worn on the forehead, and then the dry electrode sensor 58 is fitted to the user's brain. At this time, if the user generates alpha waves in a suitable environment, the dry electrode sensor 58 will transmit the collected alpha waves to the central processing module 16 for signal amplification, and then the brain wave recognition module 17 will perform recognition, judgment and analysis. The music processing module 18 will play music suitable for the current situation according to the brain wave signal at that time, and when the music is generated, the frequency modulation module 19 will also perform proportional frequency modulation according to the basic frequency (8 to 13 Hz), and finally achieve the frequency difference between the two ears to play alpha frequency music. If the dry electrode sensor 58 cannot collect the alpha waves of the human brain, the external sound source 15 can stably generate an alpha basic frequency.

[0074] Step S2: Rotating the knob 52 clockwise can drive the adjusting gear 51 to rotate clockwise. When the adjusting gear 51 rotates, it can engage and control the first arc-shaped rack 54 to rotate clockwise, driving the arc-shaped plate 53 to move clockwise, so that it can eventually drive the mounting sleeve 57 and the internal dry electrode sensor 58 to move to the right. Rotating the knob 52 counterclockwise will also drive the adjusting gear 51 to control the mounting sleeve 57 and the internal dry electrode sensor 58 to move to the left. When moving to the left or to the right, the extreme position is the separation component 6 and the interference gear 73.

[0075] Step S3: Move the mounting sleeve 57 to the left again. When the mounting sleeve 57 moves to the inclined surface of the pointed cone 62, the slide rod 63 can be controlled to slide in the mounting tube 61 to extend the separation spring 64. Finally, when the pointed cone 62 completely enters the interior of the mounting sleeve 57, the pointed cone 62 resets and resists to control the dry electrode sensor 58 and the mounting sleeve 57 to separate. In this way, the user can remove the dry electrode sensor 58 and place it on the placement seat 10 for storage during exercise or other working environments.

[0076] Step S4: When the dry electrode sensor 58 is fitted with the human brain, the user needs to wrap the strap 11 around the back of the head after wearing the mounting frame 3 and then position the positioning hole 12 in the positioning block 85. In order to ensure that the dry electrode sensor 58 can be stably fitted, it can be directly pulled to the farthest positioning hole 12 to stably ensure the fit of the dry electrode sensor 58. When the dry electrode sensor 58 is placed, it is in normal mode, so the user can temporarily adjust the positioning hole 12 to a certain position, and then slide the slider 83 to the right to control the continuous rebound of the elastic tooth plate 82, so that the distance of the positioning block 85 can be controlled to realize the positioning block. The fine adjustment of 85 can optimize the comfort. When the fine-tuning slider 83 moves to the position of the inclined plate 711, when the user wants to move the second arc-shaped rack 55 to the right, the clockwise rotating second arc-shaped rack 55 can engage and control the interference gear 73 to rotate clockwise. At this time, the interference gear 73 controls the cam 76 clockwise to squeeze the airbag 77 and pressurize the pipe 72 through the hose 78, so that the piston rod 79 will descend to control the inclined plate 711 to descend and resist the force-bearing positioning block 85. When the positioning block 85 is subjected to horizontal force, it will control the positioning pin 86 to contract, so that the slider 83 and the elastic tooth plate 82 can be separated to facilitate rapid separation.
