[0048] The following further details the specific implementation mode of the present invention in conjunction with the attached drawings.

[0049] As Figures 1 - 12 shown, a multifunctional electric guitar includes a guitar body 3 and a guitar neck 1, and the guitar neck 1 is arranged on the guitar body 3, and a circuit board four 2 and a speaker are arranged in the guitar body 3. Moreover, the use of the electric guitar also includes a switch 35 and an adjusting knob 36 for adjusting the tone or volume, which can be directly set on the guitar body 3 or adjusted on the APP of the mobile phone. When set on the guitar body 3, the circuit board four 2 is provided with related electronic components corresponding to the switch 35 and the adjusting knob 36. Therefore, when the switch 35 is toggled and the adjusting knob 36 is rotated, information can be transmitted to the circuit board four 2. Since these are existing structures and not the key points of protection, they will not be elaborated in detail.

[0050] At the same time, the guitar neck 1 includes a rotating portion 11 and a mounting portion 12, and the mounting portion 12 is arranged on the guitar body 3. Moreover, a plurality of buttons one 41 are arranged on the upper surface of the rotating portion 11, a soft rubber fretboard 5 is arranged on the lower surface of the rotating portion 11, and the rotating portion 11 is rotatably arranged at one end of the mounting portion 12. By rotating the rotating portion 11, the surface facing upwards of the rotating portion 11 can be replaced.

[0051] Therefore, during actual use, by respectively providing a soft rubber fretboard 5 and a number of first buttons 41 on the upper and lower surfaces of the neck, a neck can have two types of buttons, so it can be better applied to various scenarios, and can be switched back and forth by rotation, so the operation is very convenient.

[0052] The rotation structure between the rotating part 11 and the mounting part 12 is as follows: First, a rotating member 6 is provided between the rotating part 11 and the mounting part 12, and the rotating member 6 includes a connecting shaft 61, and a first connecting plate 62 and a second connecting plate 63 are provided on the connecting shaft 61, and the first connecting plate 62 and the second connecting plate 63 can rotate relative to each other. At the same time, the rotating part 11 is connected to the second connecting plate 63, and the mounting part 12 is connected to the first connecting plate 62.

[0053] Therefore, during actual use, by connecting the rotating part 11 to the second connecting plate 63 and connecting the mounting part 12 to the first connecting plate 62, the rotation of the rotating part 11 is realized. The rotating member 6 is an existing structure, that is, one of the damping rotating shafts.

[0054] Such as Figures 5 - 7 shown, the structure of the rotating member 6 is as follows: First, the installation of the first connecting plate 62 and the second connecting plate 63, that is, one end of the connecting shaft 61 has a thread, and a nut 65 is connected to the connecting shaft 61 to prevent the first connecting plate 62 and the second connecting plate 63 from detaching from the connecting shaft 61.

[0055] At the same time, the rotating part 1 only needs to rotate 180 degrees, so in order to prevent over-rotation, a partition 64 is provided between the first connecting plate 62 and the second connecting plate 63, and protruding parts are provided on both sides of the partition 64, and a convex block 631 is provided on the inner side of the second connecting plate 63.

[0056] Therefore, during actual use, the rotation range of the second connecting plate 63 is limited by the abutment of the convex block 631 and the protruding part.

[0057] Secondly, the structure between the rotating part 11 and the second connecting plate 63 is as follows: First, a first connecting groove 111 is opened at one end of the rotating part 11 close to the mounting part 12, and a first clamping block 112 is provided on the inner wall of the first connecting groove 111, and a second clamping groove 632 is provided on the second connecting plate 63 corresponding to the first clamping block 112.

[0058] Therefore, during actual use, by placing the second connecting plate 63 in the first connecting groove 111 and matching the adaptation of the first clamping block 112 and the second clamping groove 632, the connection between the rotating part 11 and the second connecting plate 63 is realized.

[0059] At the same time, a second connecting groove 121 is opened at one end of the mounting part 12 close to the rotating part 11, and a second clamping block 122 is provided on the inner wall of the second connecting groove 121, and a first clamping groove 621 is provided on the first connecting plate 62 corresponding to the second clamping block 122.

[0060] Therefore, during actual use, by placing the first connecting plate 62 within the second receiving groove 121 and matching the second engaging block 122 with the first engaging groove 621, the connection between the mounting portion 12 and the second connecting plate 63 is achieved.

[0061] As Figures 1 - 2 shown, there is an electrical connection between the rotating portion 11 and the mounting portion 12. Therefore, in order to avoid the existence of an electrical connection during the rotation process and to avoid the absence of an electrical connection after rotation, a detection component and / or a power connection component are provided between the rotating portion 11 and the mounting portion 12.

[0062] Meanwhile, the detection component detects the orientation of the rotating portion 11, thereby sending a signal to connect the circuit loop corresponding to the first button 41 or the circuit loop corresponding to the soft rubber finger plate 5, and the power connection component connects the circuit loop corresponding to the first button 41 or the circuit loop corresponding to the soft rubber finger plate 5 according to different orientations of the rotating portion 11.

[0063] The structure of the detection component is diverse. It can include a sensor, a first induction portion, and a second induction portion. The rotating portion 11 is respectively provided with the first induction portion and the second induction portion at one end close to the mounting portion 12, and the mounting portion 12 is provided with a sensor at one end close to the rotating portion 11.

[0064] Therefore, during actual use, by matching the first induction portion with the sensor, the first button 41 can make a sound when pressed, and by matching the second induction portion with the sensor, the soft rubber finger plate 5 can make a sound when pressed. The sensor is electrically connected to the third circuit board 9 in the mounting portion 2, and the third circuit board 9 is respectively electrically connected to the first circuit board 7 and the second circuit board 8 but is generally in an open circuit state. When the third circuit board 9 receives the signal sent by the sensor, it connects one of them.

[0065] Moreover, the detection component can also include a ball, a first gravity sensor, and a second gravity sensor. The rotating portion 11 is respectively provided with the first gravity sensor and the second gravity sensor on the upper and lower sides of the central axis between the first button 41 and the soft rubber finger plate 5, and a movable ball is provided between the first gravity sensor and the second gravity sensor.

[0066] Therefore, during actual use, when the ball moves to match the first gravity sensor, the first button 41 can make a sound when pressed, and when the ball moves to match the second gravity sensor, the soft rubber finger plate 5 can make a sound when pressed. The third circuit board 9 is respectively electrically connected to the first gravity sensor and the second gravity sensor, and the third circuit board 9 is respectively electrically connected to the first circuit board 7 and the second circuit board 8 but is generally in an open circuit state. When the third circuit board 9 receives the signal sent by the first gravity sensor, it connects the circuit with the first circuit board 7, and when the third circuit board 9 receives the signal sent by the second gravity sensor, it connects the circuit with the second circuit board 8.

[0067] Meanwhile, the structure of the power connection component is diverse. It can include a push button, a first contact, and a second contact. The push button is arranged on one side of the mounting portion 12, and the first contact and the second contact are arranged below the push button of the mounting portion 12. The first contact is wirelessly connected to the first button 41, and the second contact is wirelessly connected to the soft rubber fingerboard 5.

[0068] Therefore, during actual use, by contacting the bottom of the push button with the first contact, pressing the first button 41 can produce sound, and by contacting the bottom of the push button with the second contact, pressing the soft rubber fingerboard 5 can produce sound. The first contact and the second contact are arranged on the third circuit board 9.

[0069] Secondly, the power connection component can also include a first connector, a first interface part, and a second interface part. The mounting portion 12 is provided with a telescopic first connector at one end close to the rotating portion 11, and two openings are formed at one end of the rotating portion 11 close to the mounting portion 12 to respectively expose the first interface part and the second interface part.

[0070] Therefore, during actual use, by connecting the first connector and the first interface part, pressing the first button 41 can produce sound, and by connecting the first connector and the second interface part, pressing the soft rubber fingerboard 5 can produce sound. The first connector is arranged on the first circuit board 7, the second interface part is arranged on the second circuit board 8, and the first connector is arranged on the third circuit board 9. The telescopic property of the first connector is an existing structure and will not be elaborated here.
