Description

Technical Field

[0053] Reference Figure 1 , Fig.10 and Fig.11 As shown, both sides of the neck 2 are provided with fixing openings 12, and the slide plates 708 are slidably connected inside the fixing openings 12;

[0054] Specifically, the opening of the fixing opening 12 can facilitate the sliding of the slide plate 708 .

[0055] In combination with the above preferred embodiments, the working principle of the present invention is as follows:

[0056] In the initial state, bevel gear 2 706 and bevel gear 1 705 are in a state of mutual meshing, the telescopic shaft of electric pneumatic rod 1 501 is in an extended state, the telescopic shaft of electric pneumatic rod 2 507 is in a contracted state, the tension spring 710 is in an unstretched state, the two position clamping rollers 611 are in a separated state, and are in a state of not clamping the strings.

[0057] When working:

[0058] When a student needs to adjust the tension of the strings of the electric guitar during the process of learning electric guitar, after the student sets the value of the string tension, the controller controls the electric air rod 1 501 to start, and the telescopic shaft of the electric air rod 1 501 extends. The extension of the telescopic shaft of the electric air rod 1 501 drives the support plate 502 fixed thereon to slide down, and the sliding of the support plate 502 drives the driving motor 503 and the electric air rod 2 507 fixed thereon to slide down synchronously, so that the sliding of the driving motor 503 drives the rotating rod 504 and the limiting convex strip 505 fixed thereon to move down synchronously. The sliding of the rotating rod 504 drives the worm 509 sliding on the surface to slide synchronously, the controller controls the electric gas rod 2 507 to start, and the telescopic shaft of the electric gas rod 2 507 stretches. The extension of the telescopic shaft of the electric gas rod 2 507 pushes the connecting plate 508 fixed thereon to move, and the movement of the connecting plate 508 pushes the rotating worm 509 to slide on the rotating rod 504, so that the worm 509 and the worm wheel 1 512 corresponding to the string to be adjusted are meshed with each other. At the same time, the student controls the driving motor 503 to start through the controller, and the driving motor 503 drives the connecting plate 508 fixed thereon to move. The rotating rod 504 rotates, and the blocking force generated by the limiting convex strip 505 and the limiting groove 506 can make the rotating rod 504 drive the worm 509 on the surface to rotate synchronously, and the rotation of the worm 509 drives the meshing worm wheel 1 512 to rotate, and the rotation of the worm wheel 1 512 drives the rotating rod 510 to rotate, and the rotation of the rotating rod 510 drives the winding roller 511 fixed thereon to rotate synchronously, and the winding and releasing of the strings can be realized through the rotation of the winding roller 511, so that the tension of the strings can be controlled and adjusted, and each string can be adjusted and controlled individually. Automatic adjustment ensures that the tension of the strings reaches the precise set value, avoiding the error caused by manual adjustment, helping to obtain more accurate pitch and better sound quality. There is no need to manually adjust the tension of the strings, saving time and energy, allowing you to prepare for performance faster, and there is no need to stop frequently to adjust during performance. The tension of the strings can also be automatically adjusted according to the selected music style or preset settings to meet the tone requirements of different styles. Automatic adjustment can avoid over-tensioning the strings, reduce potential damage to the strings and instruments, and extend their service life.

[0059] At the same time, if one of the strings suddenly breaks, the pressure sensor 11 senses that the string pressure is different due to the break, and the pressure sensor 11 immediately sends a signal to the controller, and the controller controls the corresponding winding roller 511 to quickly wind up. The winding roller 511 can quickly and automatically wind up the broken string. The fast winding can prevent the string from flying away and causing harm, protecting you and the people around you. You don’t have to manually deal with the broken string, saving time and energy, and you can quickly continue playing and reduce interruptions. Automatic winding of the broken string can prevent the strings from scattering on the ground, keeping the stage clean and tidy, and will not affect the performance. Fast winding can prevent the broken string from being entangled on other parts, avoiding malfunctions and damage. The fast winding of the broken string can reduce potential damage to the instrument and prevent the string from scratching or damaging the instrument body and other parts.

[0060] And, after the tension of multiple strings is adjusted one by one, the controller controls the telescopic shaft of the electric air rod 1 501 to perform a contraction movement, and the electric air rod 1 501 drives the support plate 502 fixed thereon to slide up, and the upward sliding of the support plate 502 drives the driving motor 503 and the electric air rod 2 507 fixed thereon to slide up synchronously, so that the upward sliding of the driving motor 503 drives the rotating rod 504 and the limiting convex strip 505 fixed thereon to slide up synchronously, and the upward sliding of the rotating rod 504 drives the worm 509 sliding on the surface to slide up synchronously, and the controller controls the electric air rod 2 507 to start, and the telescopic shaft of the electric air rod 2 507 performs an extension movement, and the telescopic shaft of the electric air rod 2 507 drives the connecting plate 508 fixed thereon to move, and the movement of the connecting plate 508 drives the rotating worm 509 to slide on the rotating rod 504. The worm 509 is meshed with the worm wheel 2 602 corresponding to the string to be adjusted. At the same time, the student controls the driving motor 503 to start through the controller. The driving motor 503 drives the rotating rod 504 fixed thereon to rotate. The blocking force generated by the limiting convex strip 505 and the limiting groove 506 can make the rotating rod 504 drive the worm 509 on the surface to rotate synchronously. The rotation of the worm 509 drives the meshing worm wheel 2 602 to rotate. The rotation of the worm wheel 2 602 can make the adjusting screw sleeve 603 slide toward the direction of the neck 2 through the thread. The sliding of the adjusting screw sleeve 603 drives the moving plate 604 fixed thereon to slide on the limiting rod 605. The limiting rod 605 can limit the sliding of the moving plate 604. The sliding of the moving plate 604 drives the moving frame 606 fixed thereon to slide.

[0061] When the moving frame 606 slides in the direction of the neck 2, one end of the two moving rods 612 slides from the distance between the two guide grooves 607 that is the farthest to the distance between the two guide grooves 607. Since the guide grooves 607 are in an eight-shaped shape, when the moving frame 606 slides, the moving rods 612 and the position clamping rollers 611 are guided by the guide grooves 607 to make the two separated position clamping rollers 611 move laterally, so that the two position clamping rollers 611 move toward each other. When the position clamping rollers 611 slide, the connecting rods 610 fixed thereon slide. The sliding of the connecting rods 610 drives the sliding sleeves 609 fixed thereon to slide on the sliding rods 608. The sliding rods 608 and the sliding sleeves 609 can limit the sliding position clamping rollers 611, so as to prevent the position clamping rollers 611 from moving during the process of clamping the strings, thereby avoiding affecting the fixed position of the strings. The adjacent sides are clamped on both sides of the strings, so that the strings whose tension is adjusted can be fixed individually, so that the tension of each string is maintained at the set value, and the tension of each string is different. Individual clamping and fixing can ensure the accuracy of the pitch of each string, making the harmony and melody of the performance more accurate and harmonious. Individual clamping and fixing of each string can optimize the resonance effect of the string and make the sound fuller and richer.

[0064] At the same time, the student manually rotates the adjustment handle 803 to drive the bidirectional screw rod 802 fixed thereon to rotate, and the bidirectional threads on the bidirectional screw rod 802 can make the two sliding screw sleeves 804 move in a direction close to each other, and the two sliding screw sleeves 804 can make the adjustment connecting rod 806 rotate when the two sliding screw sleeves 804 move, and the adjustment connecting rod 806 can push the nut 805 connected to the top rotation to slide upward when the adjustment connecting rod 806 rotates, and the upward sliding of the nut 805 can make the strings in the slide groove 807 slide upward synchronously, so as to adjust the distance between the strings and the neck 2, and the adjustment of the height of the nut 805 can affect the distance between the strings and the fingerboard, thereby changing the pitch, and by properly lowering or raising the nut 805, the pitch of the strings can be adjusted more accurately to meet the needs of different musical styles or personal preferences, and if the height of the nut 805 is not appropriate, it will cause difficulty in pressing the strings or uncomfortable hand feeling, and by adjusting the nut 805 The height of the nut 805 can be adjusted to suit the finger strength and playing style, making it easier and more natural to press the strings. Lowering the height of the nut 805 can reduce the distance between the strings and the fingerboard, that is, reduce the string spacing. A smaller string spacing helps to press the strings more easily and improve playing speed and accuracy. A suitable height of the nut 805 can affect the vibration and resonance of the strings, thereby affecting the timbre. By adjusting the height of the nut 805, different timbre characteristics can be explored. Adjusting the height of the nut 805 can adapt to strings of different thicknesses to ensure that they have good pronunciation and response. If the nut 805 is worn or uneven, these problems can be solved to a certain extent by adjusting the height, restoring the normal vibration and pronunciation of the strings. Compared with the prior art, the height adjustment of the nut 805 requires the replacement of nut 805 with different heights, which can effectively reduce the learning cost.
