[0032] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," 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 limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0034] like Figure 1 As shown, this embodiment discloses a neckless steering guitar. The neckless steering guitar of this embodiment includes a neck 100, a soundbox 200, an adhesive layer 300, and a connecting assembly 400. To facilitate understanding of the technical solution of this embodiment, the directions in the accompanying drawings are first defined as follows: Figure 1 The X-axis is configured along the length of the neck 100mm, and the Y-axis is configured along the width of the neck 100mm. Figure 3 The Z-direction is configured as the thickness direction of the resonator.

[0035] like Figure 2 As shown, the neck 100 has a mounting part 111 at its tail end. The mounting part 111 has a rectangular cross-sectional shape and is used to connect to one end of the resonator 200.

[0036] like Figure 3 and Figure 4 As shown, in some preferred embodiments, the neck 100 includes a neck body 110 and a fingerboard 120. The neck body 110 is a structure with a certain length. Along the length direction of the neck body 110, a mounting part 111 is provided at one end of the neck body 110 near the soundbox 200. In the thickness direction of the neck body 110, the fingerboard 120 is connected to one side of the neck body 110. When the neck 100 is connected to the soundbox 200, there is a predetermined gap between the fingerboard 120 and the soundboard 210 of the soundbox 200. The size of the predetermined gap H is selected according to actual needs, and is generally 0.1cm to 1.2cm.

[0037] like Figure 4 As shown, in this embodiment, the fingerboard 120 of the neck 100 is suspended above the panel 210. Compared with the traditional method of bonding the fingerboard 120 to the panel 210, the suspended structure of this embodiment can release the vibration of the corresponding area of ​​the panel 210 and the fingerboard 120, making the tone fuller and the dynamic response better.

[0038] likeFigure 5 As shown, the resonator 200 includes a front panel 210, a back panel 220, and side panels 230. The front panel 210, back panel 220, and side panels 230 are connected to form a box structure. The internal space of the box structure is configured as a resonating cavity. The front panel 210, back panel 220, and side panels 230 can all refer to existing technologies, and will not be described in detail here. It should be noted that in this embodiment, the front panel 210 is recessed along the thickness direction of the resonator 200 to form a mounting groove 200a with a rectangular cross-sectional shape. Since the shape of the mounting groove 200a matches the shape of the mounting portion 111 of the neck 100, the mounting portion 111 of the neck 100 can be stably installed in the mounting groove 200a.

[0039] like Figure 4 and Figure 6 As shown, in some preferred embodiments, a reinforcing part 240 is provided in the resonance cavity. The reinforcing part 240 is connected to the inner side of the panel. The reinforcing part 240 and the panel 210 form a mounting groove 200a in a corresponding area and are connected together. Specifically, the reinforcing part 240 has three sides. The first side is connected to the inner side of the panel 210 and can cover the area corresponding to the mounting groove 200a. The second side is connected to the back plate 220 and the third side is connected to the side plate 230.

[0040] In this embodiment, a reinforcing part 240 corresponding to the mounting groove 200a is provided inside the resonance cavity, which can ensure the structural strength of the connection position between the neck 100 and the resonance box 200, thereby ensuring the stability after connection.

[0041] like Figure 4 and Figure 6 As shown, in some preferred embodiments, the reinforcing part 240 is provided with a weight-reducing hole 240a, which is opened along the thickness direction of the resonator 200 and has an elliptical cross-sectional shape. By providing a weight-reducing hole 240a in the reinforcing part 240, the weight of the reinforcing part 240 can be reduced while maintaining the structural strength of the reinforcing part 240, thus preventing the guitar from exceeding the weight limit and improving the guitar's portability.

[0042] like Figure 4 As shown, in the thickness direction of the resonator 200, a first connecting hole 200b is disposed within the reinforcing portion 240, with one end opening of the first connecting hole 200b located within the weight-reducing hole 240a, and the other end opening of the first connecting hole 200b located on the inner peripheral wall of the mounting groove 200a; a second connecting hole 200c passes through the panel 210, with one end opening of the second connecting hole 200c located on the inner peripheral wall of the mounting groove 200a, and the other end opening of the second connecting hole 200c communicating with the interior of the resonator cavity. Both the first connecting hole 200b and the second connecting hole 200c are configured as circular apertures opened along the thickness direction of the resonator 200.

[0043] like Figure 4 As shown, one end of the weight reduction hole 240a is connected to the inner side of the back plate 220, and the back plate 220 is provided with an exposure hole 220a at the position corresponding to the weight reduction hole 240a. In the thickness direction of the resonating box 200, the exposure hole 220a can expose the first connecting hole 200b located in the weight reduction hole 240a.

[0044] like Figure 4 As shown, in this embodiment, the first threaded connector 410 and the second threaded connector 420 of the connecting assembly 400 pass through the first connecting hole 200b and the second connecting hole 200c respectively. The operator can use a hand tool to reach into the weight reduction hole 240a from the exposed hole 220a on the back plate 220 to disassemble and assemble the first threaded connector 410. Similarly, the operator can use a hand tool to reach into the resonance cavity from the sound hole on the panel 210 to disassemble and assemble the second threaded connector 420 using the operating space inside the resonance cavity. In this embodiment, the first threaded connector 410 is deeply embedded inside the weight reduction hole 240a, and the second threaded connector 420 is hidden inside the resonance cavity. The two threaded connectors are hidden, which can improve the aesthetics and avoid the threaded connectors being directly exposed on the outside of the resonance box 200.

[0045] like Figure 4 As shown, the adhesive layer 300 is used to connect the surface of the mounting part 111 and the inner peripheral wall of the mounting groove 200a. The adhesive layer 300 in this embodiment can refer to the adhesive layer structure with adhesive properties in the prior art, such as leather glue or adhesive, etc.

[0046] like Figure 4 As shown, in this preferred embodiment, one side of the adhesive layer 300 is connected to the inner bottom wall of the mounting groove 200a, where the inner bottom wall of the mounting groove 200a refers to an inner wall perpendicular to the thickness direction of the resonating box 200, and the other side of the adhesive layer 300 is connected to the surface of the mounting part 111.

[0047] like Figure 4 As shown, in this embodiment, the resonator 200 and the mounting portion 111 of the neck 100 are connected together by the first threaded connector 410 and the second threaded connector 420. Meanwhile, an adhesive layer 300 is used to connect the resonator 200 and the mounting portion 111 of the neck 100 respectively, which greatly improves the stability of the connection.

[0048] It should be noted that although the use of adhesive layer 300 can significantly improve the connection performance, when the neck 100 needs to be disassembled and maintained, how to efficiently and quickly destroy the adhesive layer 300 without damaging the structure so that the neck 100 and the soundbox 200 can be separated smoothly is also a problem that needs to be solved.

[0049] likeFigure 7 As shown, in this embodiment, it is preferable that a steam guide channel 200d is provided on the inner bottom wall of the mounting groove 200a. One end of the steam guide channel 200d is connected to the first connecting hole 200b, and the other end of the steam guide channel 200d is connected to the second connecting hole 200c. When it is necessary to disassemble the neck 100, the two threaded connectors are first removed, and then high-temperature steam (the temperature of high-temperature steam is generally above 100 degrees Celsius) is introduced through the first connecting hole 200b or the second connecting hole 200c. The high-temperature steam spreads to the inner bottom wall of the mounting groove 200a through the steam guide channel 200d. Since the adhesive layer 300 is connected to the inner bottom wall of the mounting groove 200a, the adhesive layer 300 will gradually melt and release the mounting part 111 under the influence of high temperature, thereby realizing the rapid disassembly of the neck 100.

[0050] In this embodiment, the two connecting holes (i.e., the first connecting hole 200b and the second connecting hole 200c) can serve as through holes for threaded connectors to pass through during threaded connection. On the other hand, when it is necessary to disassemble the neck 100, both connecting holes can serve as inlets for high-temperature steam. High-temperature steam is introduced into the steam guide channel 200d through the connecting holes to melt the adhesive layer 300, enabling the neck 100 to be disassembled quickly without damaging the structure.

[0051] like Figure 7 and Figure 8 As shown, in this embodiment, a first positioning hole 200g is provided on the inner bottom wall of the mounting groove 200a, and a second positioning hole 100c corresponding to the first positioning hole 200g is provided on the mounting part 111. The two ends of the positioning pin 430 are respectively inserted into the first positioning hole 200g and the second positioning hole 100c, thereby realizing the positioning of the neck 100. The first positioning hole 200g and the second positioning hole 100c are preferably blind holes opened along the thickness direction of the resonator 200. In the width direction of the neck 100, the two first positioning holes 200g are respectively located on both sides of the first connecting hole 200b, and the first positioning hole 200g, the second positioning hole 100c and the positioning pin 430 are provided in a one-to-one correspondence.

[0052] like Figure 7As shown, in this preferred embodiment, the first connecting hole 200b and the second connecting hole 200c are spaced apart on the inner bottom wall of the mounting groove 200a; the steam guide groove 200d includes a main flow groove 200e and a branch flow groove 200f that are interconnected; the two ends of the main flow groove 200e are respectively connected to the first connecting hole 200b and the second connecting hole 200c, and the main flow groove 200e extends along the length direction of the neck 100. The branch flow groove 200f is also provided on the inner bottom wall of the mounting groove 200a. One end of the branch flow groove 200f is vertically connected to the main flow groove 200e. There are multiple branch flow grooves 200f, and at least one branch flow groove 200f has two ends respectively connected to the first positioning hole 200g and the first connecting hole 200b.

[0053] In this embodiment, the main flow channel 200e guides the high-temperature steam along the length of the neck 100, and the branch flow channel 200f directs the high-temperature steam to both sides in a direction perpendicular to the main flow channel 200e, so that the inner bottom wall of the mounting groove 200a is uniformly heated, and the adhesive layer 300 can be uniformly heated to accelerate the melting process. On the other hand, there may be seepage of adhesive liquid in the two connecting holes and the two first positioning holes 200g (i.e., leakage when forming the adhesive layer 300). The branch flow channel 200f connects the first positioning holes 200g and the connecting holes, so that the high-temperature steam can flow between the connecting holes and the first positioning holes 200g and melt the already solidified adhesive liquid in the first positioning holes 200g.

[0054] like Figure 4 As shown, the connecting assembly 400 includes two threaded connectors, namely a first threaded connector 410 and a second threaded connector 420. The first threaded connector 410 passes through the first connecting hole 200b and is threadedly connected to the first threaded hole 100a on the mounting part 111. The second threaded connector 420 passes through the second connecting hole 200c and is threadedly connected to the second threaded hole 100b on the mounting part 111.

[0055] like Figure 4 As shown, in this embodiment, the first threaded connector 410 passes through the first connecting hole 200b and the adhesive layer 300 in sequence, and is threadedly connected to the first threaded hole 100a. The second threaded connector 420 passes through the second connecting hole 200c and the adhesive layer 300 in sequence, and is threadedly connected to the second threaded hole 100b. In this embodiment, both the first threaded connector 410 and the second threaded connector 420 are preferably existing bolts, screws, etc.

[0056] In this embodiment, the mounting part 111 of the neck 100 can be stably connected to the mounting groove 200a by two threaded connectors.

[0057] The disassembly and assembly principle of the stemless steering guitar in this embodiment is as follows:

[0058] When the neck 100 needs to be assembled onto the soundbox 200: insert two positioning pins 430 into the first positioning hole 200g, then apply a layer of adhesive to the inner bottom wall of the mounting groove 200a (the adhesive will form an adhesive layer 300 after curing), install the mounting part 111 of the neck 100 into the mounting groove 200a, and bond the inner bottom wall of the mounting groove 200a and the mounting part 111 with the adhesive respectively. Then, securely connect the mounting part 111 into the mounting groove 200a through the first threaded connector 410 and the second threaded connector 420.

[0059] When the neck 100 needs to be removed: The worker holds a tool and inserts it into the weight reduction hole 240a through the exposed hole 220a on the back plate 220, and connects it with the first threaded connector 410 inside the weight reduction hole 240a. The first threaded connector 410 is then unscrewed. Next, the worker holds a tool and inserts it into the resonance cavity through the sound hole on the front plate 210, and connects it with the second threaded connector 420 inside the resonance cavity. The second threaded connector 420 is then unscrewed. Finally, the external high-temperature steam pipe is connected to the first connection hole 200b and / or the second connection hole 200c. The high-temperature steam is conducted into the mounting groove 200a and heat-melts the adhesive layer 300, allowing the neck 100 to be removed smoothly.

[0060] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
