[0036] Wherein, Figure 1 It is illustrated that the first end 110 and the second end 120 are located on different surfaces of the shell, so as not to affect the insertion of the audio input plug 200 into the sound hole of the guitar. Figure 3 It is illustrated that the shell 100 is a hollow structure, and the mainboard 300 is arranged inside the shell 100, and the mainboard 300 is integrated with a signal processing module and a grounding module, both of which belong to integrated circuit programs, and it is not easy to illustrate on the structure of the mainboard 300, so it can be described in detail by combining the circuit logic diagram of Figure 4 The signal processing module is connected to the original signal line (Hot) of the guitar through the audio input plug 200, and the grounding module is connected to the grounding end (GND) of the metal part of the guitar or an external device.

[0039] Preferably, in combination with reference Figures 1-3 In an embodiment, the audio input plug 200 is connected to the shell 100 through the rotating shaft 510, the axial direction of the audio input plug 200 and the rotating shaft 510 are perpendicular to each other, and the audio input plug 200 swings around the rotating shaft 510 relative to the shell 100 to adapt to the installation angle of different guitar sound holes. Here, the installation angle refers to the included angle between the audio input plug 200 and the outer wall surface of the second end 120. It can be understood that in other embodiments, the audio input plug 200 can also be fixedly connected to the shell 100, and the axial direction of the audio input plug 200 is inclined to the outer wall surface of the second end 120 to form a target installation angle. During the processing of the mute control device 10, the audio input plug 200 on the second end 120 can be processed to different installation angles according to market demand to meet the different needs of users, that is, one mute control device 10 corresponds to one installation angle of the audio input plug 200.

Among them, the end face of the rotating shaft 510 and one of the groove walls of the rotating groove 130 are provided with a glass groove 520, and the other is provided with a glass bead 530; the number of the glass bead 530 and the glass groove 520 is multiple, when the audio input plug 200 swings to different installation angles of the guitar sound hole, the glass bead 530 is positioned and embedded in the glass groove 520, so as to limit the swing of the audio input plug 200 relative to the shell 100, and the angle between the audio input plug 200 and the outer wall surface of the second end 120 is stabilized at the installation angle described above. Optionally, the number of the glass bead 530 is one, the number of the glass groove 520 is multiple and is distributed around the rotating shaft 510, in the process of self-rotation of the rotating shaft 510, the glass bead 520 jumps between different glass grooves 520 to switch the embedded position, so as to fix the installation angle of the audio input plug 200; the number of the glass bead 530 is multiple and is distributed around the rotating shaft 510, the number of the glass groove 520 is one, in the process of self-rotation of the rotating shaft 510, the glass groove 520 is positioned and embedded with different glass beads 530, so as to fix the installation angle of the audio input plug 200.

[0042] It should be noted that the common installation angle of the guitar sound hole is 15 / 30 / 45 / 60 / 75 / 90 degrees, which is an integer multiple of 15°. In order to more accurately match the installation angle of the guitar sound hole, preferably, in an embodiment, referring to Figure 2 , the number of the glass bead 530 is two and is distributed around the rotating shaft 510, the number of the glass groove 520 is one, and the radian between the two glass beads 530 with the rotating shaft 510 as the center is 15°; or, the number of the glass bead 530 is one, the number of the glass groove 520 is two and is distributed around the rotating shaft 510, and the radian between the two glass grooves 520 with the rotating shaft 510 as the center is 15°. The user has a clear sense of swing when swinging the audio input plug 200 by 15°, which can effectively remind the user of the size of the installation angle and accurately and stably install the angle. It should be understood that, in other embodiments, without considering the reminding sense and the positioning of the glass bead 530, in this application, the number of the glass bead 530 or the glass groove 520 is not limited, and whether to be provided or not is also not limited. Of course, in other embodiments, the audio input plug 200 on the sound control device 10 can be processed into 15 / 30 / 45 / 60 / 75 / 90° installation angle specifications to adapt to the installation angle of different guitar sound holes.

[0043] It needs to be understood that first, the matching arrangement of the rotating shaft 510 and the rotating groove 130 is a specific structural mode to realize the rotating connection of the audio input plug 200 to the shell 100.

In addition, the rotating shaft 510 can also achieve rotating connection by matching with the axial groove. Therefore, in the present application, the arrangement position and arrangement of the rotating groove 130 and the swing gap 140 are not limited, and any specific structural mode that can realize the rotating connection of the audio input plug 200 to the shell 100 should be protected. Second, the matching arrangement of the glass bead 530 and the glass bead groove 520 is a structure for limiting the swing angle of the audio input plug 200 and stabilizing the installation angle of the audio input plug 200. In other embodiments, the swing angle of the audio input plug 200 and the installation angle of the audio input plug 200 can also be limited by the structure of the protrusion and the arc-shaped groove, and the swing angle of the audio input plug 200 and the installation angle of the audio input plug 200 can also be limited by increasing the rotating damping by using a damping sleeve. Therefore, in the present application, the arrangement of the glass bead 530 and the glass bead groove 520 is not limited, and any specific structural mode that can limit the swing angle of the audio input plug 200 and stabilize the installation angle of the audio input plug 200 should be protected.

It should be noted that the ends of the conductive wire 600 can be electrically connected by welding, wire knotting, and contact terminals. The conductive wire 600 can be a flexible conductor structure such as a soft wire or a flexible flat cable. Since the audio input plug 200 swings and moves relative to the main board 300, the conductive wire 600 also moves and winds to a certain extent, so the wire hole 220 plays a role in guiding and preventing winding of the conductive wire 600. It needs to be understood that in other embodiments, the audio input plug 200 is fixedly connected to the shell and fixed relative to the main board 300, and the audio input plug 200 can be electrically connected to the signal processing module on the main board 300 by a contact terminal.
