[0031] In a stringless guitar, keys are located on the neck. These keys correspond to different pitches or chords, and by recognizing different keys, the guitar produces the corresponding sound, thus enabling playing. Compared to traditional guitars, stringless guitars are easier to learn and use.

[0032] To ensure comfortable key presses, stringless guitars use soft rubber keys. However, soft rubber keys have low sensitivity, requiring force to activate them, which limits the keys' ability to detect force and restricts the smoothness of playing.

[0033] Please see Figures 1 to 4The present invention provides a guitar neck 10 including a pressing layer 12, the pressing layer 12 including a main body 14 and a trigger part 16. The main body 14 includes a first surface 18 and a second surface 20 arranged opposite to each other along the thickness direction of the guitar neck 10. The first surface 18 is provided with a pressing area 22, and the trigger part 16 protrudes from the second surface 20. The trigger part 16 and the pressing area 22 are arranged correspondingly along the thickness direction of the guitar neck 10.

[0034] In the aforementioned neck 10, the first surface 18 is provided with a pressing area 22, and the trigger part 16 protrudes from the second surface 20. The trigger part 16 and the pressing area 22 are correspondingly arranged along the thickness direction of the neck 10. In this way, the pressure required to trigger the pressing area 22 can be reduced, thereby improving the sensitivity of the keys and thus improving the smoothness of the performance.

[0035] Specifically, the pressing layer 12 is disposed on the surface of the neck 10. By applying force to the pressing layer 12, the neck 10 identifies the area where the force occurs and emits a preset tone or chord corresponding to that area, thus achieving the desired playing effect. However, if the pressing layer 12 is a single piece of silicone pad, some keys, due to the small area of ​​the pressing area 22, require a larger force to cause sufficient displacement of the pressing layer 12 along the thickness direction of the neck 10, allowing the electronic instrument 100 to recognize the area where the force occurs. This may result in low sensitivity of the pressing area 22 due to insufficient force applied, limiting the range of force recognition by the electronic instrument 100 and potentially affecting the smoothness of playing the electronic instrument 100.

[0036] Based on this, the present invention provides a neck 10, the pressing layer 12 of which includes a main body 14 and a trigger part 16. The first surface 18 of the main body 14 is provided with a pressing area 22, and the second surface 20 is provided with a trigger part 16. The trigger part 16 and the pressing area 22 are correspondingly arranged along the thickness direction of the neck 10.

[0037] The pressing layer 12 includes a flexible pressing layer 12. The thickness of the main body 14 is less than the thickness of the trigger part 16. The trigger part 16 protrudes relative to the main body 14. This makes the outer periphery of the trigger part 16 relatively thin, changing the elastic distribution of the pressing layer 12 and making the pressure more concentrated in the pressing area 22. Thus, when a force is applied to the pressing area 22, the pressing force required for triggering can be reduced, and the triggering efficiency can be improved.

[0038] like Figure 2 As shown, the thickness direction of the neck 10 is... Figure 2 The front and back direction of the neck 10 is as follows: Figure 2 The vertical direction of the neck and the width direction of the neck are as follows: Figure 2 The left and right directions in the middle.

[0039] In one embodiment, the body 14 and the trigger portion 16 are obtained by an integral molding process. For example, the pressing layer 12 includes a solid silicone rubber pressing layer 12 or a liquid silicone rubber pressing layer 12, and the body 14 and the trigger portion 16 of the pressing layer 12 are formed by compression molding or injection molding.

[0040] In one embodiment, a trigger portion 16 can be provided on a thin flexible pressing layer 12 by means of adhesive or other methods, so that the trigger portion 16 protrudes from the second surface 20 of the main body 14.

[0041] In one embodiment, the trigger portion 16 can be protruding from the second surface 20 of the main body 14 by removing the material around the pressing area 22 on the second surface 20 of the thicker flexible pressing layer 12.

[0042] In some embodiments, the ratio of the projected area of ​​the pressing area 22 in the thickness direction of the neck 10 to the projected area of ​​the trigger portion 16 corresponding to the pressing area 22 in the thickness direction of the neck 10 is related to the size of the pressing area 22.

[0043] In this way, the size of the pressing area 22 and the trigger part 16 can be reasonably designed according to the area of ​​the pressing area 22 corresponding to the area of ​​the trigger part 16, so that all pressing areas 22 maintain high sensitivity.

[0044] Specifically, when the area of ​​the pressing area 22 is large, the thickness of the pressing layer 12 has a smaller impact on the displacement of the trigger part 16 along the thickness direction of the neck 10. At the same time, when the area of ​​the pressing area 22 is large, the area that the user can press is also large, so a larger corresponding trigger part 16 is beneficial to the triggering of the pressing area 22.

[0045] When the area of ​​the pressing area 22 is small, the thickness of the pressing layer 12 has a significant impact on the displacement of the trigger part 16 along the thickness direction of the neck 10. At the same time, when the area of ​​the pressing area 22 is small, the area that the user can press is also small. Thus, a smaller corresponding trigger part 16 will not affect the triggering of the pressing area 22.

[0046] In some embodiments, the pressing area 22 includes a first pressing area and a second pressing area. The area of ​​the first pressing area is larger than the area of ​​the second pressing area. The projected area of ​​the first pressing area in the thickness direction of the neck 10 is greater than or equal to the projected area of ​​the trigger part 16 corresponding to the first pressing area in the thickness direction of the neck 10. The projected area of ​​the second pressing area in the thickness direction of the neck 10 is greater than the projected area of ​​the trigger part 16 corresponding to the second pressing area in the thickness direction of the neck 10.

[0047] In this way, the trigger units 16 corresponding to the pressing area 22 can be reasonably distributed within the limited space of the pressing area 22.

[0048] Specifically, the larger the projected area of ​​the pressing area 22 in the thickness direction of the neck 10, the larger the projected area of ​​the trigger part 16 corresponding to the pressing area 22 in the thickness direction of the neck 10; conversely, the smaller the projected area of ​​the pressing area 22 in the thickness direction of the neck 10, the smaller the projected area of ​​the trigger part 16 corresponding to the pressing area 22 in the thickness direction of the neck 10.

[0049] like Figure 2 As shown, Class A keys 24 and Class B keys 26 are arranged in parallel along the width direction of the neck 10, Class C keys 28 and Class D keys 30 are arranged in parallel along the width direction of the neck 10, Class A keys 24 and Class B keys 26, Class C keys 28 and Class D keys 30 are arranged at intervals along the length direction of the neck, Class E keys 32 are arranged separately on one side of the neck, and multiple Class F keys 34 are arranged in parallel along the width direction of the neck 10.

[0050] The first pressing area includes type A keys 24 and type E keys 32. Type A keys 24 and type E keys 32 have large areas, resulting in relatively high trigger sensitivity when the area of ​​the trigger part 16 is the same as that of the first type of keys. The second pressing area includes type B keys 26, type C keys 28, type D keys 30, and type F keys 34. These keys have small areas, so the area of ​​the pressing area needs to be smaller than the area of ​​the pressing area 22 to facilitate triggering the corresponding keys.

[0051] Because the neck 10 has a limited area, the sizes of the pressing areas 22 and the trigger parts 16 are rationally designed according to the area of ​​the pressing area 22 corresponding to the area of ​​its trigger part 16, so that all pressing areas 22 can maintain high sensitivity. Thus, when the user applies a consistent pressing force to pressing areas 22 of different sizes during the use of the electronic musical instrument 100, they can obtain relatively consistent feedback and response. This allows the user to operate more smoothly and accurately, improving the fluency of playing the electronic musical instrument 100.

[0052] In some embodiments, the second pressing area includes a first sub-pressing area and a second sub-pressing area. The area of ​​the first sub-pressing area is larger than the area of ​​the second sub-pressing area. At least one edge of the projection of the first sub-pressing area in the thickness direction of the neck 10 and the projection of the trigger part 16 corresponding to the first sub-pressing area in the thickness direction of the neck 10 do not coincide. The edges of the projection of the second sub-pressing area in the thickness direction of the neck 10 and the projection of the trigger part 16 corresponding to the first sub-pressing area in the thickness direction of the neck 10 do not coincide.

[0053] Thus, by setting the position of the trigger part 16 according to the area of ​​the pressing area 22, the trigger sensitivity of the pressing area 22 can be guaranteed, while the pressing layer 12 can be guaranteed to have good strength and support.

[0054] Specifically, such as Figure 2As shown, the first sub-pressing area includes type B key 26, and the second sub-pressing area includes type C key 28, type D key 30, and type F key 34. The area of ​​type B key 26 is larger than that of type C key 28, type D key 30, and type F key 34. Therefore, the area of ​​the pressing area corresponding to type B key 26 can be larger than that of the pressing areas corresponding to type C key 28, type D key 30, and type F key 34.

[0055] Understandably, the larger the total area of ​​the trigger portions 16 of all pressing areas 22, the better the overall strength and support of the pressing layer 12. Simultaneously, after the pressing areas 22 are pressed, the elasticity of the main body 14 is needed to allow the trigger portions 16 to return to their initial positions. Furthermore, since the area of ​​the pressing layer 12 is limited, and the A-type bonds 24 to F-type bonds 34 need to be distributed according to a certain pattern.

[0056] In summary, the projection of the first sub-pressing area onto the thickness direction of the neck 10 can be designed so that at least one edge of the projection of the corresponding trigger part 16 onto the thickness direction of the neck 10 does not coincide with the projection of the first sub-pressing area onto the thickness direction of the neck 10. This means that at least one edge of the trigger part 16 corresponding to the first sub-pressing area has a thinner edge. Similarly, the projection of the second sub-pressing area onto the thickness direction of the neck 10 and the projection of the corresponding trigger part 16 onto the thickness direction of the neck 10 do not coincide with the projection of the second sub-pressing area onto the thickness direction of the neck 10. This means that all four perimeters of the trigger part 16 corresponding to the second sub-pressing area are thinner. In this way, while ensuring the trigger sensitivity of the pressing area 22, the pressing layer 12 can also be guaranteed to have good strength and support.

[0057] Optionally, the projection of the first sub-pressing area in the thickness direction of the neck 10 and the projection of the trigger part 16 corresponding to the first sub-pressing area in the thickness direction of the neck 10 do not coincide on one side; or, the projection of the first sub-pressing area in the thickness direction of the neck 10 and the projection of the trigger part 16 corresponding to the first sub-pressing area in the thickness direction of the neck 10 do not coincide on two or more sides.

[0058] Please see Figure 1 and Figure 2 In some embodiments, along the thickness direction of the neck 10, the plane containing the second sub-pressing area is higher than the plane containing the first sub-pressing area.

[0059] In this way, the area of ​​the second sub-press area is smaller than that of the first sub-press area, and the plane on which the second sub-press area is located is higher than that on the plane on which the first sub-press area is located. When the user triggers the smaller second sub-press area, accidental touches can be effectively avoided.

[0060] Specifically, the plane containing the second sub-press area is higher than the plane containing the first sub-press area, creating a physical separation in space. When the user operates the device, especially during complex and rapid playing actions, the height difference makes it less likely for the finger to accidentally touch the higher second sub-press area when it contacts the first sub-press area. This height separation of the pressing areas 22 reduces accidental triggering and improves the accuracy of operating commands during performance.

[0061] At the same time, since the second sub-press area is small and high, the triggering force required when pressing can be further reduced, so that the triggering force of the smaller second sub-press area is consistent with the triggering force of other larger pressing areas 22.

[0062] Furthermore, the height difference between the first and second sub-press areas provides a different tactile experience. When the user's finger moves from the first sub-press area to the second sub-press area, they can clearly feel the change in position and the increase in height. This tactile feedback provides the user with clear operational cues, helping them better perceive their actions and further improving operational accuracy.

[0063] Please see Figure 2 and Figure 3 In some embodiments, the projection of the trigger portion 16 corresponding to the first sub-pressing area in the thickness direction of the neck 10 does not coincide with the projection of the first sub-pressing area in the thickness direction of the neck 10 on the side near the edge of the neck 10.

[0064] This improves the sensitivity of the pressing area 22 at the edge of the neck 10.

[0065] Specifically, the edge of the pressing layer 12 is close to the housing 32, making it more difficult for the trigger part 16 corresponding to the pressing area 22 at the edge of the pressing layer 12 to be pressed.

[0066] The projection of the trigger part 16 corresponding to the first sub-pressing area in the thickness direction of the neck 10 and the projection of the first sub-pressing area in the thickness direction of the neck 10 do not coincide on the side near the edge of the neck 10. That is, the edge thickness of the first sub-pressing area near the neck 10 housing 32 is thinner. In this way, the pressing sensitivity of the first sub-pressing area near the neck 10 housing 32 can be improved.

[0067] like Figure 3As shown, type A keys 24 and type B keys 26 are arranged in parallel along the width direction of the neck 10. The edge of type B key 26 is close to the housing 32. Therefore, the projection of the corresponding trigger part 16 of type B key 26 in the thickness direction of the neck 10 does not coincide with the projection of type B key 26 in the thickness direction of the neck 10 on the side near the edge of the neck 10. That is, the edge thickness of type B key 26 on the side near the housing 32 of the neck 10 is thinner. This makes the sensitivity of type B key 26 on the side near the edge of the neck 10 higher.

[0068] In summary, by reducing the force required to trigger the pressing area 22 and increasing its sensitivity, the pressing area 22 can have a wider force recognition range, thereby expanding the force recognition function of the neck 10. Taking an electric guitar as an example, the player can control the volume and intensity through different force variations, thus achieving more delicate sound effect control. This makes the electric guitar suitable for complex musical expression, and by adjusting the sound intensity in real time, the performance becomes more expressive.

[0069] Furthermore, the dynamic feedback feature allows for the development of more innovative techniques, such as glissando, vibrato, and pitch fine-tuning, enriching playing styles. For example, the glissando feature enables players to achieve smooth pitch transitions on the fretboard, increasing the expressiveness and emotional depth of the music. The glissando feature is particularly suitable for styles such as modern fingerstyle, electronic music, and experimental music, providing players with more creative space and thus also enabling the creation of standalone passages.

[0070] Please see Figure 4 In some embodiments, the ratio of the thickness H1 of the main body 14 to the sum of the thicknesses H2 of the main body 14 and the trigger part 16 along the thickness direction of the neck ranges from [0.480, 0.572].

[0071] In this way, by reducing the pressure required to trigger the pressing area 22, the overall strength of the pressing layer 12 can be guaranteed.

[0072] Specifically, when the thickness H1 of the main body 14 decreases and the sum of the thicknesses H2 of the main body 14 and the trigger part 16 increases, the pressure required to trigger the pressing area 22 can be reduced. However, a decrease in the thickness H1 of the main body 14 may lead to a decrease in the overall strength of the pressing layer 12 and a deterioration in the flatness of the first surface 18 of the pressing layer 12. At the same time, if the sum of the thicknesses H2 of the main body 14 and the trigger part 16 is too large, the overall thickness of the pressing layer 12 may be too large, which is not conducive to installation and may cause accidental activation.

[0073] Therefore, the ratio H1 / H2 of the thickness H1 of the main body 14 to the sum of the thicknesses H2 of the main body 14 and the trigger part 16 is in the range of [0.480, 0.572]. That is, the value of H1 / H2 can be 0.480, 0.500, 0.510, 0.515, 0.525, 0.535, 0.545, 0.555, 0.565 or 0.572, or any other value within the range [0.480, 0.572].

[0074] In some embodiments, the neck 10 includes a main control board and a sensing layer 30. The pressing layer 12, the sensing layer 30 and the main control board are stacked in sequence. The sensing layer 30 and the main control board are electrically connected. When the pressing area 22 is subjected to pressure, the trigger part 16 presses against the sensing layer 30 so that the sensing layer 30 comes into contact with the main control board.

[0075] In this way, different pressing positions and pressure levels can be identified.

[0076] Specifically, when the pressing area 22 is subjected to pressure, the trigger part 16 presses against the sensing layer 30. Since the triggering force is relatively small, the sensing layer 30 can accurately sense the magnitude and change of the triggering pressure. Thus, the main control board can perform diverse processing and feedback based on the pressure signal transmitted by the sensing layer 30. Besides controlling basic sound production, it can also achieve some special sound effects or functions. For example, based on different pressing forces and durations of the strings, special effects such as glissando and vibrato can be achieved, enriching the expressiveness of the electronic musical instrument 100 and providing performers with more creative space.

[0077] The sensing layer 30 is electrically connected to the main control board, which can accurately transmit this pressure information to the main control board in the form of electrical signals. This allows the main control board to judge the player's key press force and other operations based on different pressure values, thereby achieving precise control of the instrument's sound production and other functions. For example, when playing the electronic instrument 100, different volumes of sound can be emitted according to the different pressure applied to the keys.

[0078] The sensing layer 30 is directly abutted and electrically connected to the main control board, which reduces the intermediate links and distances in signal transmission, shortens the signal transmission time, and enables a fast response. At the same time, the sensing layer 30 and the main control board form a relatively stable signal transmission channel, which can reduce the interference of the external environment on the signal.

[0079] After the performer presses the button, the sensing layer 30 can quickly transmit the pressure signal to the main control board, which can also react quickly, so that the instrument can emit sound or perform the corresponding function in time, ensuring the smoothness and real-time performance.

[0080] In addition, the pressing layer 12, the sensing layer 30 and the main control board are stacked in sequence, which makes the internal structure of the neck 10 more compact and integrates a variety of functional modules within the limited space of the neck 10, which helps to reduce the volume of the neck 10.

[0081] Please see Figure 3 and Figure 5 In some embodiments, the sensing layer 30 includes a high-resistivity carbon film, on which a carbonized area 31 corresponding to the position of the trigger portion 16 is provided.

[0082] In this way, pressure sensing can be achieved accurately.

[0083] Specifically, each trigger part 16 has a corresponding carbon coating area on the high-resistivity carbon film. The user's force is applied to the pressing area 22. The force causes the trigger part 16 and the carbon coating area to have different contact areas, which in turn affects the contact area between the high-resistivity carbon film and the main control board, thereby realizing the trigger function and force feedback.

[0084] When the trigger part 16 presses against the high-resistivity carbon film with the carbon coating area 31, the resistance of the carbon coating area 31 will change significantly and stably with the change of pressure, so that the sensing layer 30 can accurately convert the pressure signal into an electrical signal. The main control board can accurately determine the pressing force, position and other information based on the change of electrical signal, thereby realizing performance control. For example, different pitch and timbre changes can be corresponding to different pressing forces and positions of the fingers.

[0085] The physical and electrical properties of the high-resistivity carbon film enable it to respond quickly to changes in resistance when subjected to pressure and to rapidly return to its initial state after the pressure is removed. This allows the electronic musical instrument 100 to recognize rapid, continuous pressing or pressing again after a brief pause, preventing signal delays or loss and ensuring smooth and accurate playing.

[0086] Furthermore, the high-resistivity carbon film possesses a certain degree of hardness and wear resistance, enabling the carbon-coated area 31 to withstand repeated pressure from the trigger part 16 without easily experiencing wear or damage. During long-term, frequent use, the sensing performance of the high-resistivity carbon film remains relatively stable, reducing performance degradation or malfunctions caused by component wear, thereby extending the service life of the neck 10 sensing system.

[0087] In some embodiments, the neck 10 includes a housing 32, which has a receiving groove, and the pressing layer 12, the sensing layer 30 and the main control board are stacked and arranged in sequence and housed in the receiving groove.

[0088] This allows for a compact structure for the neck 10.

[0089] Specifically, components such as the pressing layer 12, the sensing layer 30, and the main control board are placed in the receiving slot and protected by the housing 32. This reduces the impact of external environmental factors (such as collisions, dust, and moisture) on the internal components, lowers the risk of component damage, extends the service life of the neck 10 and the entire electronic musical instrument 100, and improves its stability in different usage environments.

[0090] The receiving slot provides a relatively fixed installation position for components such as the pressing layer 12, the sensing layer 30, and the main control board, so that the pressing layer 12, the sensing layer 30, and the main control board can maintain a relatively stable positional relationship. During the use of the instrument, the layers will not easily shift or shake, thus ensuring the stability and reliability of the neck 10.

[0091] Integrating components such as the pressing layer 12, the sensing layer 30, and the main control board into a single receiving slot simplifies the assembly process of the neck 10. During assembly, simply placing the pressing layer 12, the sensing layer 30, and the main control board into the receiving slot sequentially and securing them completes the assembly. This reduces assembly steps and required parts, improves production efficiency, and lowers production costs.

[0092] Furthermore, if a component inside the neck 10 malfunctions, since the layers are stacked within the receiving slot, they are relatively independent and easy to disassemble. Maintenance personnel can easily open the housing 32, locate the faulty component, and replace it without having to disassemble and reassemble the entire neck 10 structure on a large scale, thus reducing maintenance difficulty and cost.

[0093] Please see Figure 3 and Figure 5 In some embodiments, the housing 32 includes positioning posts, and positioning holes 34 are respectively formed in the pressing layer 12, the sensing layer 30 and the main control board. The positioning posts pass through the positioning holes 34 so that the pressing layer 12, the sensing layer 30 and the main control board overlap in sequence.

[0094] This ensures assembly precision and stable triggering function of the neck 10.

[0095] Specifically, the cooperation between the positioning post and the positioning hole 34 precisely defines the relative positions of the pressing layer 12, the sensing layer 30, and the main control board, ensuring that each layer can be accurately overlapped and avoiding offset or misalignment between layers. This ensures accurate correspondence between the trigger part 16 and the carbonized area 31 of the sensing layer 30, and a good electrical connection between the sensing layer 30 and the main control board, thereby improving the sensing accuracy and stability of the entire system and ensuring that the instrument can accurately respond to the player's operations.

[0096] The positioning pins pass through the positioning holes 34 to allow the pressing layer 12, the sensing layer 30, and the main control board to overlap sequentially. This effectively restricts the movement of the pressing layer 12, the sensing layer 30, and the main control board within the plane, keeping the relative positions of each layer fixed. During instrument use, even if subjected to vibration or external force, the layers are unlikely to shift, thus ensuring the reliability and stability of the system and reducing the probability of problems such as poor contact and signal interruption caused by interlayer movement.

[0097] During the production and assembly process, the design of the positioning posts and positioning holes 34 provides guidance for the installation of each layer. During assembly, simply pass the positioning posts through the corresponding positioning holes 34 to quickly achieve the sequential overlapping installation of the pressing layer 12, the sensing layer 30, and the main control board. There is no need for complex measurement and calibration work, which greatly improves the assembly efficiency, reduces labor costs, and is also conducive to achieving large-scale automated production.

[0098] In summary, by making the trigger portion 16 of the pressing layer 12 protrude from the body, the sensitivity of the pressing layer 12 can be improved, and the trigger pressure can be reduced. This allows the neck 10 to be more sensitive to the trigger force, giving it a dynamic feedback function. This enhances performance expressiveness and realism, allowing the player to achieve more nuanced sound control through different dynamic variations. It is suitable for complex musical expressions, allowing for real-time adjustment of sound intensity and making the performance more expressive. Furthermore, the electronic musical instrument 100 with higher sensitivity and dynamic feedback can expand upon more playing techniques, such as glissando, vibrato, and pitch fine-tuning, thus enriching playing styles and providing players with more creative space.

[0099] Please see Figure 1 The present invention provides an electronic musical instrument 100, which includes the neck 10 of any of the above embodiments.

[0100] In the aforementioned electronic musical instrument 100, the first surface 18 is provided with a pressing area 22, and the trigger part 16 protrudes from the second surface 20. The trigger part 16 and the pressing area 22 are correspondingly arranged along the thickness direction of the neck 10. In this way, the pressure required to trigger the pressing area can be reduced, thereby improving the sensitivity of the keys and thus improving the smoothness of the performance.

[0101] Specifically, electronic musical instruments 100 include, but are not limited to, electronic guitars, electronic pipa, electronic liuqin, electronic yueqin, electronic pianos, etc.
