Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, in particular to a digital guitar lower stringer and a digital guitar. Background Art

[0002] Digital guitar is a new type of electronic plucked string instrument that has emerged in recent years, using the electronic sound generation principle of sensors, chip software algorithms and sampling sound source technology. As an important structure for guitar sound generation, the way the strings are fixed can directly affect the quality of the sensor's pickup signal and thus the sound quality.

[0003] Digital guitars usually use shorter strings, and only need to obtain the amplitude information at the beginning of the plucking without obtaining complete and continuous vibration frequency information. Therefore, the string holder is quite different from that of ordinary guitars. Generally, six very short strings are used. The digital guitars in the prior art directly fix the lower ends of the strings to the soundboard, which will cause problems such as excessive tension or too small amplitude, which will lead to a smaller amplitude collected by the pickup. In addition, the residual vibration generated by the plucked strings will interfere with the signal of the pickup and affect the sound quality. At the same time, users cannot adjust the feel of the strings in a personalized way, and the experience is poor. In addition, most digital guitars can only use specific models or special strings. When the strings are worn and damaged, it is very inconvenient to replace them. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0040] like Figures 1 to 3 As shown, this embodiment provides a lower string fixing structure for a digital guitar, which is arranged on the soundboard 100 of the digital guitar and is used to fix the lower end of the strings 200. The lower string fixing structure includes a plurality of connecting members 1 and a plurality of fixing members 2. The plurality of connecting members 1 are arranged on the soundboard 100 at intervals along a first horizontal direction, and each connecting member 1 is provided with a connecting hole 10 that passes through in a vertical direction; each connecting member 1 is correspondingly provided with a fixing member 2, and each fixing member 2 includes a connecting portion 21 and a mounting portion 22 that are connected in sequence, and the connecting portion 21 is arranged in an adjustable position in the connecting hole 10. A flexible member 211 is provided in the connecting portion 21, and a first channel 2110 is provided on the flexible member 211, which passes through the vertical direction. A mounting cavity 220 is provided on the mounting portion 22, and an elastic member 221 and a clamping member 222 are provided in the mounting cavity 220. The elastic member 221 abuts between the flexible member 211 and the clamping member 222, and a second channel 2210 is provided on the elastic member 221, which passes through the vertical direction. The lower end of the string 200 is fixed on the clamping member 222, and passes through the second channel 2210 and the first channel 2110 in sequence, and extends to the upper string fixing device. The setting of the elastic member 221 ensures that the string 200 has an appropriate degree of tightness even when it is in a tight state. When the user plucks the string 200, it is convenient to pluck a larger amplitude, thereby obtaining a better string plucking feel. At the same time, the amplitude collected by the pickup is also larger. The setting of the flexible member 211 can effectively reduce the abnormal sound of the plucked string 200 due to the collision with the inner wall of the fixing member 2. After obtaining the amplitude at the beginning of the plucking, the residual vibration of the string 200 should be eliminated as much as possible. The residual vibration will interfere with the signal of the pickup, etc. By eliminating the residual vibration, a simpler pickup signal is obtained, which is conducive to improving the sound quality. In addition, the fixing member 2 is adjustable in position in the connecting hole 10 on the connecting member 1, and the user can adjust the feel in a personalized way to enhance the experience. The lower string fixing structure can also support any universal string 200 as the string 200 of the digital guitar, which has high applicability and is convenient for self-replacement at a later time.

[0041] Optionally, an internal thread is provided on the inner wall of the connecting hole 10, and an external thread is provided on the outer peripheral wall of the connecting part 21, so that the connecting part 21 and the connecting member 1 can be detachably connected through threaded cooperation; at the same time, it is convenient for the user to adjust a single string 200, which is conducive to enhancing the experience and feel of use.

[0042] Specifically, six connecting members 1 and six fixing members 2 are provided.

[0043] For example, Figure 3 As shown, in this embodiment, the elastic member 221 is a spring; the flexible member 211 is a silicone tube with good flexibility. In addition, along the first horizontal direction and / or the second horizontal direction, the size of the elastic member 221 is larger than the size of the clamping member 222, so that the clamping member 222 can fix the lower end of the string 200 and prevent the clamping member 222 from sliding into the second channel 2210; the size of the elastic member 221 is smaller than the size of the flexible member 211, so as to ensure that the elastic member 221 abuts against the flexible member 211 and prevent the elastic member 221 from sliding into the first channel 2110.

[0044] Optionally, refer to Figure 2 The side wall of the mounting cavity 220 away from the end of the connecting portion 21 is hexagonal. The above arrangement makes it easy to use a hexagonal wrench to screw the fixing member 2 to adjust the tension of the strings 200, so that the user can fine-tune the strings 200 in a targeted manner and enhance the personalized experience.

[0045] Optionally, a groove 2220 is formed on the clamping member 222, and the string 200 is clamped in the groove 2220, so that the string 200 is fixed and the stability of the fixing of the string 200 is improved.

[0046] Optionally, the structure further includes a plurality of vibration dampers 3 arranged at intervals along the first horizontal direction. Each vibration damper 3 includes a plug-in portion 31 and two vibration damping plates 32, the plug-in portion 31 is inserted into the piano board 100, the two vibration damping plates 32 are connected to the plug-in portion 31, and the two vibration damping plates 32 are arranged on both sides of the string 200 along the first horizontal direction. When the string 200 is plucked, the vibration damper 3 can quickly eliminate the vibration of the string 200, so that the pickup can collect the maximum amplitude of the string 200 in the early stage, avoiding subsequent vibration interference; at the same time, it can also eliminate the noise caused by the vibration of the string 200 itself, avoid mutual interference between two adjacent strings 200, and thus ensure the sound quality of the string 200.

[0047] Furthermore, in this embodiment, the vibration damper 3 is made of a silicone material and has good flexibility.

[0048] Alternatively, if Figure 3As shown, a receiving groove 101 is provided on the piano board 100, and a first fixing plate 4 is detachably provided in the receiving groove 101. The first fixing plate 4 is provided with a plurality of plug holes 41 spaced apart along the first horizontal direction, and each plug hole 41 extends along the second horizontal direction, and the plug part 31 is inserted into the plug hole 41. The first horizontal direction, the second horizontal direction and the vertical direction are perpendicular to each other. The above arrangement makes the installation of the vibration damper 3 more convenient and the operation simpler.

[0049] Illustratively, in this embodiment, a plurality of vibration dampers 3 are all plugged into a first fixing plate 4 ; in other embodiments, a plurality of first fixing plates 4 may also be provided, so that each vibration damper 3 is correspondingly provided with a first fixing plate 4 .

[0050] Further, refer to Figure 3 The plug-in portion 31 is provided with an anti-slip portion 311 , which can pass through the plug-in hole 41 and abut against the first fixing plate 4 on one side to prevent the vibration damper 3 from slipping out of the plug-in hole 41 , thereby ensuring the stability of the installation of the vibration damper 3 .

[0051] Specifically, the outer peripheral wall of the plug-in portion 31 is tapered, which makes it easy to insert the plug-in portion 31 into the plug-in hole 41 and can effectively prevent the plug-in portion 31 from slipping out of the plug-in hole 41, further enhancing the installation stability of the vibration damper 3.

[0052] Specifically, in this embodiment, a plurality of first fastening holes are formed on the first fixing plate 4 , and fasteners such as bolts or screws commonly used in the art are passed through the first fastening holes to achieve detachable connection of the first fixing plate 4 to the accommodating groove 101 .

[0053] Optionally, the structure further comprises a plurality of second fixing plates 5, which are detachably arranged on the piano board 100, and each second fixing plate 5 is provided with a connector 1. The above arrangement facilitates the installation and fixation of the connector 1, and subsequent maintenance and replacement are also very convenient.

[0054] Specifically, each second fixing plate 5 is provided with a plurality of second fastening holes, and fasteners such as bolts or screws commonly used in the art are passed through the second fastening holes to achieve a detachable connection between the second fixing plate 5 and the soundboard 100 .

[0055] Illustratively, in this embodiment, each second fixing plate 5 is provided with two second fastening holes.

[0056] On the other hand, this embodiment also provides a digital guitar, including any of the above-mentioned digital guitar lower string fixing structures, which has all the beneficial effects of the above-mentioned digital guitar lower string fixing structures and will not be described in detail here.

[0057] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
