For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0033] Please refer to Figure 1-Figure 10 In the first aspect, the utility model provides a guitar neck, comprising a plastic shell 1 and a cover 5 covering the plastic shell 1. Of course, natural light cannot penetrate the wall thickness of the plastic shell 1 from the outside of the plastic shell 1 into the plastic shell 1. An indicator light 20 is provided in the plastic shell 1. A light slot 101 is provided in the plastic shell 1 at a position corresponding to the indicator light 20. Referring to FIG. Figure 2 A thin-walled light-transmitting portion 102 is formed between the wall surface of the lamp trough 101 facing the indicator light 20 and the outer wall surface of the plastic housing 1. The thin-walled light-transmitting portion 102 transmits the light emitted by the indicator light 20 to the outside of the plastic housing 1, and the thin-walled light-transmitting portion 102 isolates natural light, so that natural light cannot penetrate the thin-walled light-transmitting portion 102 into the plastic housing. That is, it can be understood that by arranging the indicator light 20 inside the plastic shell 1 of the guitar neck, and opening a lamp groove 101 at the position corresponding to the indicator light 20 in the plastic shell 1, and the wall thickness between the wall surface of the lamp groove 101 facing the indicator light 20 and the outer wall surface of the plastic shell 1 forms a thin-walled light-transmitting portion 102. Since the natural light transmittance of the thin-walled light-transmitting portion 102 is zero, the natural light outside the guitar neck cannot penetrate the thin-walled light-transmitting portion 102, so that the user cannot see the position of the indicator light 20 from outside the guitar neck, while the light emitted by the indicator light 20 inside the guitar neck when it is lit can be transmitted through the thin-walled light-transmitting portion 102 to the outside of the plastic shell 1, so that the indicator light 20 plays an indicating role.

[0034] In summary, the indicator light 20 on the guitar neck of the utility model can play an indicating role when it is lit, and can be invisible inside the guitar neck when it is off, thereby overcoming the defect that when the indicator light 20 on the existing guitar neck is off, the user can still see the position of the indicator light 20 from outside the guitar neck, resulting in the indicator light 20 not having a hiding effect when it is off, making the overall appearance of the guitar neck simple and beautiful.

[0035] In one embodiment, a plurality of fret keys are arranged at intervals along the length direction of the neck on the surface of the cover 5 facing away from the plastic housing 1, and correspondingly, a plurality of indicator lights 20 are provided. The plurality of indicator lights 20 correspond one-to-one to the plurality of fret keys; the light slot 101 is provided with a plurality of thin-walled light-transmitting portions 102, and the plurality of thin-walled light-transmitting portions 102 correspond one-to-one to the plurality of indicator lights 20, and each indicator light 20 is used to display the pressing state of each fret key. It can be seen that one fret key corresponds to one indicator light 20, and one indicator light 20 corresponds to one thin-walled light-transmitting portion 102, so that when the user presses a fret key, the indicator light 20 corresponding to the fret key to be pressed will be lit, which plays an indicating role, and at the same time guides the user to press the key at the corresponding position when playing.

[0036] Of course, in order to control each indicator light 20, a control board 2 extending along the length direction of the guitar neck is provided on the side wall inside the plastic shell 1. The control board 2 is a circuit board. The control board 2 can be powered by a battery provided in the plastic shell 1. Each indicator light 20 is fixed on the control board 2 and electrically connected to the control board 2. The main function of the control board 2 is to control each indicator light 20 to display the pressing status of each fret key.

[0037] In one embodiment, for example, there are 7 frets on the neck, and the frets are the frets of the guitar, and the 7 frets are fret I, fret II, fret III, fret IV, fret V, fret VI, and fret VII; Fig.10 , then there are also 7 fret buttons, namely fret I button 51, fret II button 52, fret III button 53, fret IV button 54, fret V button 55, fret VI button 56, and fret VII button 57; correspondingly, there are also 7 indicator lights 20, which are indicator light A, indicator light B, indicator light C, indicator light D, indicator light E, indicator light F, and indicator light G. When the user plays, pressing the fret I button 51 will trigger the indicator light A to light up, and when switching from the fret I button to the fret V button 55, the indicator light F will light up, and so on.

[0038] It should be noted that, since the fret button triggering indicator light 20 is a prior art in the field of smart guitar technology, the fret button triggering indicator light 20 on the guitar neck will not be described here.

[0039] The indicator light 20 uses LED lamp beads, which can improve the brightness of the indicator light 20.

[0040] In one embodiment, the side wall on which the control panel 2 is arranged on the plastic shell 1 is the first side wall 10, and the first side wall 10 is connected with a support portion 11 extending along the length direction of the guitar neck and located inside the plastic shell 1, and the support portion 11 fixes and supports the control panel 2. The control panel 2 can be fixed to the support portion 11 by riveting or gluing, which is not limited here, as long as the control panel 2 can be fixed to the support portion 11.

[0041] Of course, after the control board 2 is fixed, the indicator light 20 is located between the first side wall 10 and the control board 2, and the lamp slot 101 is provided on the first side wall 10, so that the light emitted by the illuminated indicator light 20 is transmitted from the thin-walled light-transmitting portion 102 on the first side wall 10 to the outside of the guitar neck. In order to improve the indication effect of the indicator light 20, a light guide structure 103 is provided at one end of the lamp slot 101 close to the indicator light 20. The light guide structure 103 is a chamfered structure provided at one end of the lamp slot 101 close to the indicator light 20, so that the light emitted by the indicator light 20 will be guided into the lamp slot 101 through the light guide structure 103, and then transmitted from the thin-walled light-transmitting portion 102 to the outside of the guitar neck. In other words, it can be understood that the light guide structure 103 plays a role in concentrating light, avoiding the dispersion of light emitted by the indicator light 20 into the lamp slot 101, and improving the indication effect of the indicator light 20.

[0042] In one embodiment, in order to facilitate the installation and positioning of the control board 2, a positioning hole 21 penetrating the relative surface of the control board 2 is opened, and a positioning column 13 adapted to the positioning hole 21 is fixed on the first side wall 10. The control board 2 can be quickly positioned by cooperating with the positioning column 13 and the positioning hole 21.

[0043] In one embodiment, the lamp trough 101 is a circular hole structure. Of course, in other embodiments, the lamp trough 101 may also be a long strip structure, which is not limited here. Therefore, for those skilled in the art, by reasonably setting the structure of the lamp trough 101, it should also fall within the protection scope of the present utility model.

Each display surface 30 is provided with a key signature (guitar key signature), and the key signatures on each display surface 30 are different. Each display surface 30 is provided with a chord mark of its own key signature, and the key signature and the chord mark on the display surface 30 can be displayed through the display slot 12.

[0045] It should be noted that one key signature corresponds to a set of neck fret chord information, a set of neck fret chord information has multiple chord marks, and the multiple chord marks correspond to multiple fret keys one by one. Of course, the length of the display surface 30 covers each fret, and the fret chord information of different key signatures is different. A set of neck fret chord information includes multiple chord marks, and the multiple chord marks on each display surface 30 are arranged at intervals along the length direction of the display surface 30. The multiple chord marks on each display surface 30 correspond to multiple frets one by one according to the order of the frets. For example, there are 7 commonly used key signatures in guitar, namely C, D, E, F, G, A, and B. The fret chord information of the key signature of C is: C, Dm, Em, F, G, Am, and Bm. The chord mark C of the fret chord information of the key signature of C corresponds to fret I, the chord mark Dm corresponds to fret II, the chord mark Em corresponds to fret III, the chord mark F corresponds to fret IV, the chord mark G corresponds to fret V, the chord mark Am corresponds to fret VI, and the chord mark Bm corresponds to fret VII. After switching the key signature, such as switching from the C key signature to the D key signature, the fret chord information of the D key signature is: Dm, Em, F, G, Am, Bm, C, The chord mark Dm of the fret chord information of the D key corresponds to fret I, the chord mark Em corresponds to fret II, the chord mark F corresponds to fret III, the chord mark G corresponds to fret IV, the chord mark Am corresponds to fret V, the chord mark Bm corresponds to fret VI, and the chord mark C corresponds to fret VII. After the D key signature is switched to the E key signature, the fret chord information of the E key signature is: Em, F, G, Am, Bm, C, Dm. The chord marks of the fret chord information of the E key: Em, F, G, Am, Bm, C, Dm correspond to fret I, fret II, fret III, fret IV, fret V, fret VI, fret VII respectively, and so on.

[0046] In one embodiment, illustratively, the rotating cylinder 3 has 7 display surfaces 30, and the 7 display surfaces 30 correspond to the 7 key signatures mentioned above, and the chord marks of each key signature are recorded on each display surface 30 of the rotating cylinder 3, such as Figure 7 As shown, the effect diagram of the key signature of C and the chord mark of C key signature being engraved on one display surface 30. Of course, the key signature of D and the chord mark of D key signature can be engraved on another display surface 30, and so on.

[0047] In one embodiment, for example, there are three display surfaces 30 on the rotating cylinder 3, namely, a first display surface, a second display surface, and a third display surface. The key signature set on the first display surface is C key signature, the key signature set on the second display surface is D key signature, and the key signature set on the third display surface 30 is E key signature; then the fret chord information of the C key signature on the first display surface: C, Dm, Em, F, G, Am, Bm, C correspond to fret I, fret II, fret III, fret IV, fret V, respectively. , fret VI, fret VII; the fret chord information of the D key signature on the second display surface: Dm, Em, F, G, Am, Bm, C correspond to fret I, fret II, fret III, fret IV, fret V, fret VI, fret VII respectively; the fret chord information of the E key signature on the third display surface: Em, F, G, Am, Bm, C, Dm correspond to fret I, fret II, fret III, fret IV, fret V, fret VI, fret VII respectively, and so on.

[0048] In summary, when the C key signature and the fret chord information of the C key signature on the first display surface are exposed and displayed through the display slot 12, the chord information C, Dm, Em, F, G, Am, Bm of the C key signature correspond to frets I, II, III, IV, V, VI, and VII respectively; when the rotating cylinder 3 is turned to switch the first display surface to the second display surface, the D key signature and the fret chord information of the D key signature on the second display surface are exposed and displayed through the display slot 12, and the fret chord information Dm, Em, F, G, Am, and Bm of the D key signature on the second display surface correspond to frets I, II, III, IV, V, VI, and VII respectively. m, F, G, Am, Bm, C correspond to frets I, II, III, IV, V, VI, VII respectively; when the rotating cylinder 3 is turned to switch the second display surface to the third display surface, the E key signature and the fret chord information of the E key signature on the third display surface are exposed and displayed through the display slot 12, while the fret chord information of the D key signature on the second display surface, Em, F, G, Am, Bm, C, Dm correspond to frets I, II, III, IV, V, VI, VII respectively.
