[0059] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0060] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0061] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0062] like Figure 1 , Figure 2As shown, this utility model provides a stringless playing module, including a housing 10. The housing 10 has a playing surface 11, on which a plurality of playing keys 12 are provided. A main control board 13, a plucking mechanism 14, and a button PCB board 15 are disposed inside the housing 10. The plucking mechanism 14 is connected to the main control board 13. The button PCB board 15 is disposed below the corresponding playing key 12 and electrically connected to the main control board 13. The plucking mechanism 14 has a plucking blade 16, the end of which protrudes from the playing surface 11. This utility model designs a novel stringless playing module that can be used on musical instruments, especially electric musical instruments, enabling a combined keyboard and stringless playing performance, providing a completely new playing method. The playing keys 12 can be either mechanical or touch-sensitive; this utility model preferably uses touch-sensitive keys.

[0063] like Figure 3 , Figure 4 As shown, further, the stringless playing module provided by this utility model includes a plucking mechanism 14 comprising a plucking rotating component 17, a reset component 18 for resetting the plucking rotating component 17, a rotating frame 19, and a sensor 20 for sensing the rotation of the plucking rotating component 17. The rotating frame 19 and the sensor 20 are fixed inside the housing 10. The plucking rotating component 17 is mounted on the rotating frame 19, and the reset component 18 is connected to the plucking rotating component 17. The sensor 20 of this utility model can accurately detect the plucking speed and angle of the plucking paddle 16, capture subtle physical changes, and convert them into electrical signals in real time. These electrical signals can further trigger voltage adjustments in the internal circuit, thereby finely controlling the vibration frequency and amplitude of the instrument strings. This not only enhances the expressiveness of the music but also allows the performer to easily explore and express a variety of different musical styles, from classical to modern, from gentle to passionate. Various styles of music can be interpreted more richly and accurately in this way.

[0064] Furthermore, in the stringless playing module provided by this utility model, the plucking rotating component 17 includes a rotating shaft 21, the plucking piece 16 is disposed on the rotating shaft 21, and the rotating frame 19 has a first support 22 and a second support 23, the first support 22 and the second support 23 are spaced apart, and both the first support 22 and the second support 23 are provided with rotating grooves 24, and the two ends of the rotating shaft 21 are respectively connected to the two rotating grooves 24. Furthermore, in the stringless playing module provided by this utility model, a limiting protrusion 25 is provided in one of the rotating grooves 24. In this embodiment, the limiting protrusion 25 is located on the first support 22, and the rotating shaft 21 is correspondingly provided with a limiting groove 26 for limiting the rotation range of the plucking component. The limiting protrusion 25 is assembled in the limiting groove 26, which is fan-shaped. The limiting protrusion 25, in conjunction with the limiting protrusion 25, can simply limit the rotation angle of the rotating shaft 21, thereby limiting the plucking range of the plucking piece 16. Specifically, the stringless playing module provided by this utility model includes a plucking mechanism 14 that further includes a shaft fixing member 27 and a reset bracket 28. The rotating frame 19 includes a hollow frame plate 29. The first bracket 22 and the second bracket 23 are respectively fixed to the two ends of the hollow part of the frame plate 29. The shaft fixing member 27 includes a fixing pin 30 connected to one end of the rotating shaft 21 and a fixing ear 31 inserted from one side of the frame plate 29 and fixedly connected to the frame plate 29. The reset bracket 28 is installed at the other end of the rotating shaft 21. The reset bracket 28 is connected to the sensing end of the sensor 20 or located in the sensing area of ​​the sensor 20. The reset member 18 is installed on the reset bracket 28. The rotating frame 19 of this utility model is hollow, which not only reduces the weight of the parts, but also reduces the contact area with the rotating shaft 21, thus reducing the friction when the rotating shaft 21 moves. The rotating shaft 21 is installed on the rotating frame 19, and one end is first connected to the reset bracket 28. Then, the shaft fixing part 27 can be inserted horizontally from the outside. The fixing pin 30 is installed at the other end of the rotating shaft 21. At the same time, the fixing ear 31 overlaps the rotating plate. Then, the fixing ear 31 and the rotating plate can be fixed in the housing 10 with screws. The rotating shaft 21 is thus fixedly assembled between the shaft fixing part 27 and the reset bracket 28.

[0065] Specifically, the stringless playing module provided by this utility model has a wedge-shaped groove 32 on the playing surface 11 for limiting the range of motion of the plectrum 16. The plectrum mechanism 14 includes a plectrum rotating component 17, a reset component 18 for resetting the plectrum rotating component 17, a rotating frame 19, and a sensor 20 for sensing the rotation of the plectrum rotating component 17. The rotating frame 19 and the sensor 20 are fixed inside the housing 10. The plectrum rotating component 17 is mounted on the rotating frame 19. The reset component 18 is connected to the plectrum rotating component 17. The lower part of the wedge-shaped groove 32 has a slot 33 that mates with the rotating frame 19. The rotating shaft 21 is clamped between the slot 33 and the rotating frame 19. The plectrum 16 is inserted into the wedge-shaped groove 32 from the slot 33. The sensor 20 is a potentiometer. Several playing keys 12 are arranged in an orderly manner on one side of the wedge-shaped groove 32. Sensor 20 can be selected from various sensor types, such as potentiometers, rotary encoder switches, Hall effect switches, and photoelectric sensors. Sensor 20 can be directly integrated and fixed onto the main control board 13, resulting in a more compact structure, more efficient space utilization, and improved overall integration. The main function of sensor 20 is to monitor the movement of the spring 16. Specifically, when the spring 16 is operated, its mechanical movement can be converted into an electrical signal by a potentiometer or rotary encoder switch. Furthermore, a Hall effect switch can capture the movement of the spring 16 through magnetic induction and convert it into an electrical signal. Similarly, a photoelectric sensor can also sense the activity of the spring 16 and generate a corresponding electrical signal. These converted electronic signals can be used for further processing and control, enabling the device to respond more accurately to user operations.

[0066] In this embodiment, the sensor 20 is a potentiometer, and the sensing end of the potentiometer is a potentiometer column 34. The potentiometer column 34 is connected to the rotating shaft 21 through the reset bracket 28. When the rotating shaft 21 rotates, the reset bracket 28 and the potentiometer column 34 rotate simultaneously. The potentiometer uses the potentiometer column 34 to monitor the toggle angle of the spring 16 in real time. This setting allows the potentiometer to adjust its resistance value according to the specific angle change of the spring 16. In this way, the sensor 20 can accurately control the voltage and circuit state, ensuring that the system can respond quickly and accurately to various toggle angles of the spring 16. This precise control mechanism greatly improves the performance and reliability of the device, enabling it to adapt to various complex operational requirements. The reset component 18 of this utility model is a torsion spring, mounted on the reset bracket 28. It generally has two elastic ends, one of which can be fixed to the rotating plate and the other fixed to the reset bracket 28. When the reset bracket 28 rotates, it causes the two elastic ends to twist relative to each other, allowing the torsion spring to gain elastic potential energy. Of course, the reset component 18 can be configured in various ways in this field. Those skilled in the art can replace it with commonly used parts and connection methods, all of which are within the protection scope of this utility model.

[0067] Preferably, in the stringless playing module provided by this utility model, the playing key 12 is provided with a light effect position, and a light board 37 is provided inside the housing 10. The LEDs of the light board 37 are disposed below the corresponding playing key 12, and the light board 37 is electrically connected to the main control board 13. Further, in the stringless playing module provided by this utility model, the light effect position on the playing key 12 is a light effect hole 35, and the button PCB board 15 is provided with several through holes 36. The light board 37 is an LED light board 37, located below the button PCB board 15. A light guide plate 38 is provided between the light board 37 and the button PCB board 15, and the light guide plate 38 is provided with several light guide components 39 that are assembled with the light effect holes 35 and through holes 36. Further, in the stringless playing module provided by this utility model, the playing key 12 is a touch key, and the button PCB board 15 is a touch PCB board. This invention can achieve lighting effects, providing ambient lighting during performances, and also serving as an indicator light to guide performances or indicate pressed keys.

[0068] This utility model also provides another embodiment, adopting a different plucking mechanism scheme, preferably, such as Figure 5 , Figure 6 As shown, the stringless playing module provided by this utility model includes a plucking and rotating component 17 comprising a rotating shaft 21, a plucking piece 16 disposed on the rotating shaft 21, and a rotating frame 19 comprising a lower support 40 and a fixing pin 30. The lower support 40 is provided with a rotating groove 24, one end of the rotating shaft 21 is engaged with the rotating groove 24 of the lower support 40, and the other end of the rotating shaft 21 is connected to the fixing pin 30. Specifically, the fixing pin 30 is fixed to the side wall inside the housing 10, and the lower support 40 is fixed to the bottom inside the housing 10.

[0069] Furthermore, in the stringless playing module provided by this utility model, the plucking mechanism 14 further includes a reset bracket 28. The reset bracket 28 is connected to one end of the rotating shaft 21. The reset bracket 28 is connected to the sensing end of the sensor 20 or located within the sensing area of ​​the sensor 20. The reset member 18 is mounted on the reset bracket 28. A pair of collision ears 41 are provided on the reset bracket 28. One or a pair of collision blocks 42 are provided below the collision ears 41. In this embodiment, there is a pair of collision blocks 42. The frame 40 has ribs (not labeled in the figure) on the side where the collision block 42 is located. The two collision blocks 42 are sandwiched on both sides of the ribs. When the reset bracket 28 rotates to the point where the collision ear 41 contacts the collision block 42, the collision ear 41 contacts the surface of the collision block 42. This can reduce noise and wear. Specifically, a collision block 41 that cooperates with the reset bracket 28 is provided below the reset bracket 28. The collision block 41 is a soft collision block. The collision block 41 is a silicone collision block, which can further reduce impact and noise.

[0070] This utility model also provides a musical instrument, including a main body and the stringless playing module described above, which is mounted on the main body. The stringless playing module can be used in musical instruments, such as stringless guitars. The main body can supply power to the stringless playing module and receive electrical signals from the stringless fingerboard. It can convert these electrical signals into corresponding acoustic signals to achieve electroacoustic conversion, thus enabling stringless musical performance. This electroacoustic conversion is a relatively mature technology in electronic musical instruments, and those skilled in the art can select appropriate sound sources and design according to actual needs. This utility model is a modular functional component that can be installed on a musical instrument or removed for replacement with other operating modules. It can also be powered by a separate battery.

[0071] In summary, this utility model designs a novel stringless playing module that can be used on musical instruments, especially electric musical instruments, enabling a combined keyboard and stringless playing style, providing a completely new playing method. This stringless playing module can be used on musical instruments, such as stringless guitars.
