[0032] 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.
[0033] Stringless guitars typically have multiple LEDs on their necks to guide the player's keystrokes or for decorative purposes. When a single LED is used as the light source, a long light guide will appear brighter in the middle and darker at the ends. Due to space limitations within the neck, the distance between the light guide and the light source cannot be too far. Related technologies use multiple LEDs to make the light from the long light guide more even. However, the limited internal space of a stringless guitar neck means that using multiple LEDs would take up more space and increase costs.
[0034] Please see Figures 1 to 4 The present invention provides a violin neck 10 including a housing 12, a light source and a light guide 16. An accommodating space 18 is formed inside the housing 12, and the light source and the light guide 16 are accommodated in the accommodating space 18. The light guide 16 includes a light-incident part 20, which is configured to convert the light emitted from the light source into parallel light rays that propagate within the light guide 16.
[0035] In the aforementioned neck 10, the light-incident section 20 is configured to convert the light emitted from the light source into parallel light rays that propagate within the light guide 16. This enables the light guide 16 to achieve a uniform light guiding effect, thereby reducing the number of light sources, which helps to reduce space occupation and lower costs.
[0036] Specifically, the light source and light guide 16 are housed within the receiving space 18 of the housing 12. The light emitted by the light source propagates and exits through the light guide 16. The light guide 16 can convert divergent light sources into parallel light rays, preventing localized over-brightness or under-brightness within the light guide 16. Simultaneously, the parallel light transmission path is more concentrated, reducing the number of reflections and energy loss within the light guide 16, thus improving light transmission efficiency. Furthermore, stable parallel light output reduces dependence on the power of the light source, lowering energy consumption and extending the lifespan of the light source.
[0037] It should be noted that the light propagates parallel within the light guide 16, where parallel light is allowed to have a certain angular deviation. For example, the allowable deviation angle of the light propagating within the light guide 16 can be determined based on the brightness difference of the light-emitting surface of the light guide 16. In other words, by obtaining the brightness difference between the brightest and darkest points of the light-emitting surface, if this brightness difference is within a preset range, then the deviation angle between the current light propagation direction within the light guide 16 and the standard parallel direction is an allowable deviation angle.
[0038] Optionally, the light emitted from the light source can be converted into parallel light rays propagating within the light guide 16 by optimizing the material of the light guide 16. For example, a material with high light transmittance can be selected to reduce light loss during propagation. Alternatively, a gradient refractive index material can be used so that the light rays are naturally collimated within the light guide 16 due to the gradual change in refractive index, guiding the light rays to maintain parallel propagation.
[0039] Alternatively, the light emitted from the light source can be converted into parallel light rays that propagate within the light guide 16 by optimizing the structure of the light guide 16, for example by improving the surface precision of the light guide 16 through mechanical polishing, chemical etching, or laser processing, thereby reducing light scattering and ensuring that the light propagates along the designed path.
[0040] Please see Figures 6 to 11In some embodiments, the light-incident portion 20 includes a light-incident surface 22 disposed toward the light source, and the light-incident surface 22 is a curved surface recessed toward the light source.
[0041] In this way, the light guide column can achieve uniform light transmission.
[0042] Specifically, the light emitted by the light source propagates in all directions, and the concave curved surface has a larger surface area than the flat surface, which can capture light that might otherwise miss the flat light incident surface 22, thereby improving the light collection efficiency and allowing more light to enter the light guide 16.
[0043] Meanwhile, the concave curved surface can change the range of the incident angle of light, allowing light from a wider range of angles to be effectively collected and enter the light guide 16. The light-incident surface 22 is a concave curved surface facing the light source, which can make the light-incident part 20 form a concave lens structure that is thin in the middle and thick at the edges. When light is emitted from the light source, the light entering the light-incident part 20 from the middle of the light-incident surface 22 propagates in a basically straight line, while the light entering the light-incident part 20 from the edge of the light-incident surface 22 is refracted by the thicker edge of the light-incident part 20, so that the light entering the light-incident part 20 from the edge has a basically the same propagation direction as the light entering the light-incident part 20 from the middle of the light-incident surface 22. In this way, the light-incident part 20 can convert the light emitted from the light source into parallel light propagating within the light guide 16.
[0044] Therefore, based on the diverging effect of a concave lens on light, parallel light rays can be dispersed, allowing the light from the LED to be emitted more evenly. This improves the propagation efficiency of light in the light guide 16, reduces scattering and loss of light during propagation, and ensures that more light can propagate along the predetermined path to the light emission section 26.
[0045] After being refracted by the concave curved surface, the light can be distributed more evenly after entering the light guide 16. This helps to improve the light guiding effect of the light guide 16, avoids the situation where the light guide 16 is too bright or too dark in some places, and makes the output light softer and more uniform.
[0046] It is understandable that the light-incident surface 22 is a concave curved surface facing the light source, which allows the light-incident portion 20 to form a concave lens structure that is thin in the middle and thick at the edges. Positioning the light source at the focal point of the concave lens structure improves the light-guiding effect of the light-incident portion 20. Simultaneously, the curvature of the concave curved surface 22 facing the light source is related to the length of the light guide 16, wherein the length direction of the light guide is... Figure 6 The up and down directions are shown in the diagram.
[0047] Furthermore, because the recessed curved light-incident surface 22 can collect and utilize light more effectively, the power requirement for the light source can be reduced while achieving the same lighting or display effect. This reduces the energy consumption of the device and also lowers the overall cost of the neck 10 by using a lower-power, lower-cost light source.
[0048] In one embodiment, the light guide column is made of transparent ABS (Acrylonitrile Butadiene Styrene). The light guide column is made by mixing light-diffusing powder into the transparent ABS. By setting the light-incident surface 22 as a concave curved surface facing the light source, the light-incident part 20 can form a concave lens structure that is thin in the middle and thick at the edges, thereby achieving uniform light guiding.
[0049] Please see Figure 4 , Figures 6 to 11 In some embodiments, the light guide 16 further includes a support portion 24 and a light emitting portion 26. The light emitting portion 26 is disposed on the support portion 24. The housing 12 includes a bottom shell 28 with a through hole 30. The light emitting portion 26 is accommodated in the through hole 30. The inner wall surface of the bottom shell 28 abuts against the support portion 24 to fix the relative position of the light guide 16 and the bottom shell 28.
[0050] In this way, the position of the light guide 16 can be positioned on the housing 12, which facilitates installation.
[0051] Specifically, the light-emitting part 26 is housed in the through hole 30, ensuring that the light is emitted in a preset direction and range. The through hole 30 serves to position and guide the installation of the light-emitting part 26, allowing the light guide 16 to be accurately installed on the base shell 28, thus simplifying the installation process. During installation, simply align the light-emitting part 26 with the through hole 30 and insert it to complete the initial positioning. Then, the inner wall of the base shell 28 will naturally abut against the support part 24. Figure 4 As shown, the light guide 16 is fixed, thereby ensuring the relative positional accuracy between the light guide 16 and the light source.
[0052] The inner wall of the bottom shell 28 abuts against the support part 24, so that the inner wall of the bottom shell 28 has a limiting effect on the light guide 16, and at the same time provides stable support and fixation for the light guide 16, enabling the light guide 16 to resist certain external impacts and vibrations, and ensuring that the light guide 16 will not easily shift or shake during use.
[0053] Please see Figure 1 , Figures 6 to 11 In some embodiments, the light-emitting part 26 includes a columnar light-emitting part 26, the cross-section of the columnar light-emitting part 26 along the length direction is one of a waist-shaped, rectangular, polygonal or circular shape, and the shape of the through hole 30 corresponds to the cross-sectional shape of the light-emitting part 26 along the length direction.
[0054] In this way, different light emission effects can be achieved by using different shapes of the cross-section along the length direction.
[0055] Specifically, the light from the light source enters through the light guide and exits through the light emitting part 26. The light emitting part 26 is housed in the through hole 30 opened in the housing 12, so that the light emitting part 26 can emit light from its end face on the housing 12.
[0056] When the shape of the through-hole 30 corresponds to the cross-sectional shape of the light-emitting part 26 along its length, the loss of light between the light-emitting part 26 and the through-hole 30 can be minimized. The close fit between the two avoids the scattering and refraction of light at the gap, allowing the light to be emitted more directly, thereby enhancing the brightness and clarity of the emitted light.
[0057] The matching shapes of the light-emitting part 26 and the through hole 30 provide better support and positioning for the light guide 16. The columnar light-emitting part 26 fits tightly with the through hole 30 to prevent the light guide 16 from shaking or shifting during use, ensuring the stability of the installation of the light guide 16 and the base shell 28.
[0058] In one implementation, such as Figure 1 As shown, the neck 10 includes multiple light guides 16. Each light guide 16 includes a light-emitting portion 26 with a waist-shaped cross-section along its length and a light-emitting portion 26 with a circular cross-section along its length. The light guides 16 with the two types of light-emitting portions 26 are arranged alternately, which can illuminate the sequence of keys at different positions on the neck 10 or serve as decorative ambient lights on the neck 10.
[0059] Please see Figure 3 and Figure 5 In some embodiments, the light-incident portion 20 is disposed on the support portion 24, and the bottom shell 28 includes a mounting base, with the support portion 24 mounted on the side of the support portion 24 away from the light-incident portion 20.
[0060] In this way, the light guide 16 can be positioned and mounted on the bottom shell 28.
[0061] Specifically, the cooperation between the support 24 and the mounting base can position the light guide 16 on the bottom shell 28, so that the light-inlet portion 20 of the light guide 16 maintains a relatively fixed positional relationship with other components, ensuring the accuracy and stability of light transmission, which is beneficial to improving the performance of the optical system. For example, in lighting equipment, it can ensure that the light propagates at the correct angle and path to achieve the expected lighting effect.
[0062] The support part 24 of the light guide 16 is installed on the mounting base of the bottom shell 28, which provides stable support for the light guide 16, making it less likely to shift, shake or fall off when subjected to external impact or vibration. This improves the stability and reliability of the internal structure of the entire neck 10 and can effectively avoid problems such as light leakage and light path deviation caused by the loosening of the light guide 16.
[0063] By fixing the support 24 to the mounting base, the connection between the light guide 16 and the bottom shell 28 can be made tighter, reducing the possibility of light leakage from the gap between the light guide 16 and the bottom shell 28 during transmission, thereby improving the utilization efficiency of light, reducing light loss, and improving brightness uniformity.
[0064] Optionally, the support portion 24 of the light guide 16 and the mounting base can be connected by means of snap-fit connection, fastener connection, adhesive connection, etc.
[0065] Alternatively, in one implementation, such as Figure 3 and Figure 5 As shown, the mounting base includes a strip-shaped reinforcing rib 34 disposed on the base shell 28. A through groove 36 is formed on the reinforcing rib 34, which is arranged along the length of the base shell 28. When the light guide 16 is installed onto the base shell 28, the support portion 24 of the light guide 16 is aligned with the through groove 36 on the reinforcing rib 34 and inserted, so that the support portion 24 is at least partially engaged in the through groove 36, thus achieving the installation of the light guide 16. The reinforcing rib 34 serves to strengthen the structure of the base shell 28 and also supports the installation of the light guide 16. This strengthens the base shell 28 and ensures the stability of the light guide 16 installation.
[0066] In some embodiments, the support portion 24 is formed with one of a retaining strip and a through groove 36, and the mounting base is formed with the other of a retaining strip and a through groove 36. The retaining strip is engaged in the through groove 36 to fix the relative position of the light guide 16 and the bottom shell 28.
[0067] This facilitates the positioning and installation of the light guide 16 within the housing 12.
[0068] Specifically, the locking strip is engaged in the through slot 36, which can limit the position of the light guide 16 and effectively prevent the light guide 16 from shifting or rotating on the bottom shell 28. This stable connection method can withstand a certain amount of external force and vibration. Even if it is subjected to a certain impact or shaking during use, the light guide 16 can remain in its original position, ensuring its stability and reliability.
[0069] Meanwhile, the cooperation between the clip and the through slot 36 provides precise positioning for the light guide 16, ensuring that the light guide 16 is in the correct position on the bottom shell 28. This ensures that the light output position and angle of the light guide 16 meet the requirements, and also ensures that the relative position of the light guide 16 and the light source is fixed. This helps maintain the correct posture of the light guide 16, allowing the light to propagate along the preset path within the light guide 16. It avoids abnormal scattering and refraction of light inside due to positional deviation of the light guide 16, ensuring a smooth light path and improving the uniformity of the light guiding effect.
[0070] Furthermore, the installation of the light guide 16 via the locking strip and through slot 36 simplifies the installation process. Simply align the locking strip with the through slot 36 and snap it in to initially secure the light guide 16 to the base shell 28, eliminating the need for additional tools or complex operations. This reduces assembly difficulty, improves production efficiency, and is suitable for mass production. When maintenance, replacement, or cleaning of the light guide 16 is required, simply removing the locking strip from the through slot 36 allows for easy removal of the light guide 16 from the base shell 28, facilitating subsequent operations and reducing maintenance costs and time.
[0071] Please see Figure 4 In some embodiments, the light guide 16 includes a limiting part 40, which is disposed on the side of the support 24 away from the light emitting part 26. The housing 12 also includes a front shell 42, and the bottom shell 28 and the front shell 42 form an accommodating space 18. The front shell 42 includes a limiting post 44, which abuts against the limiting part 40 to fix the relative position of the light guide 16 and the bottom shell 28.
[0072] In this way, the relative position of the light guide 16 in the housing 12 can be kept stable.
[0073] Specifically, the limiting part 40 is provided on the side of the support part 24 away from the light-emitting part 26. The light-emitting part 26 is housed in the through hole 30 opened in the housing 12. The support part 24 around the light-emitting part 26 abuts against the housing 12, which can limit the displacement of the light guide 16 toward the housing 12. The limiting part 40 is provided on the side of the support part 24 away from the light-emitting part 26, and the limiting post 44 on the faceplate 42 abuts against the limiting part 40, thereby limiting the position of the light guide 16 away from the housing 12.
[0074] Thus, when the limiting post 44 abuts against the limiting part 40, the light guide 16 is fixed on the bottom shell 28, preventing the light guide 16 from moving within the accommodating space 18 in the directions toward and away from the shell 12. The light guide 16 experiences virtually no displacement within the shell 12, thereby preventing any deviation in the position of the light guide 16 from affecting the light propagation path and light emission effect, and ensuring that the optical properties of the light guide 16 remain unaffected.
[0075] Furthermore, vibrations may occur during the use of the electronic musical instrument 100. By fixing the light guide 16 by the limiting post 44 abutting against the limiting part 40, the vibration resistance of the light guide 16 can be effectively enhanced. Even if the electronic musical instrument 100 is subjected to a certain degree of vibration, the light guide 16 can maintain a relatively stable position, reducing loosening or displacement caused by vibration, thereby ensuring the stability and reliability of its operation.
[0076] Please see Figure 2 and Figure 4 In some embodiments, the housing 12 includes a bottom housing 28 and a front housing 42, which together form an accommodating space 18, and the light guide 16 is mounted on the bottom housing 28.
[0077] Thus, the accommodating space 18 formed by the bottom shell 28 and the front shell 42 provides an installation position and protection for the light guide 16. At the same time, the separate design of the front shell 42 and the bottom shell 28 facilitates assembly.
[0078] Specifically, the accommodating space 18 formed by the bottom shell 28 and the front shell 42 provides a relatively enclosed and safe environment for the light guide 16, which can prevent the light guide 16 from being affected by external dust, moisture, collisions and other factors, reduce the risk of damage or performance degradation of the light guide 16 caused by external factors, and thus extend the service life of the light guide 16.
[0079] Mounting the light guide 16 on the base shell 28 provides a basic positioning for its installation and accommodates the position of the light emitting part 26, ensuring a stable mounting base for the light guide 16 within the accommodating space 18. The base shell 28 provides support and fixation for the light guide 16, reducing shaking or displacement during use and ensuring its positional accuracy, thereby guaranteeing the stability of light propagation and distribution.
[0080] The installation of the light guide 16 is relatively separate from the assembly process of the front shell 42 and the bottom shell 28, which simplifies the assembly steps. During assembly, the light guide 16 can be installed on the bottom shell 28 first, and then the front shell 42 can be assembled with the bottom shell 28, thereby reducing the assembly difficulty and improving production efficiency.
[0081] In some embodiments, the periphery of the bottom shell 28 is provided with one of a slot and a buckle, and the periphery of the front shell 42 is provided with the other of a slot and a buckle. The buckle is engaged in the slot to fix the front shell 42 and the bottom shell 28 together.
[0082] In this way, the bottom shell 28 and the front shell 42 can be installed quickly.
[0083] Specifically, the bottom shell 28 and the front shell 42 are fixedly connected by slots and clips. During installation, simply align and press the slots and clips to complete the installation. In this way, the slots and clips simultaneously provide positioning and fixed connection for the bottom shell 28 and the front shell 42. The engagement between the slots and clips provides a certain degree of connection strength, ensuring that the front shell 42 and the bottom shell 28 are tightly joined together. This prevents loosening or separation during normal use, ensuring the stability of the overall product structure.
[0084] Optionally, in one embodiment, multiple slots and buckles are evenly distributed around the periphery of the bottom shell 28 and the top shell 42. This makes the connection between the bottom shell 28 and the top shell 42 more reliable. When the neck 10 is subjected to external impact or vibration, the engagement of the buckles and slots can distribute the external force to all the connection points of the slots and buckles, avoiding stress concentration at a certain point and causing the buckle to break. This enhances the impact and vibration resistance of the neck 10 and extends the service life of the neck 10.
[0085] Furthermore, the bottom shell 28 and the front shell 42 are fixedly connected by slots and buckles, which makes the installation of the bottom shell 28 and the front shell 42 simple and reliable, with fewer installation steps, and relatively low skill requirements for operators, reducing labor costs and the risk of product damage due to improper operation.
[0086] Alternatively, in one embodiment, the bottom shell 28 and the front shell 42 can be connected using other detachable connection methods, such as threaded connection, magnetic connection, etc.
[0087] Alternatively, in one embodiment, the bottom shell 28 and the top shell 42 can be fixedly connected using other connection methods, such as bonding with tape or glue.
[0088] Please see Figure 2 and Figure 3 In some embodiments, the front shell 42 has a first connecting hole 50, the bottom shell 28 has a second connecting hole 52, and the neck 10 includes a fastener that passes through the first connecting hole 50 and the second connecting hole 52 to fix the bottom shell 28 and the front shell 42.
[0089] This ensures the stability of the connection between the front shell 42 and the bottom shell 28.
[0090] Specifically, the bottom shell 28 and the top shell 42 are connected by fasteners. The fasteners provide strong connection force, increasing the stability of the connection between the top shell 42 and the bottom shell 28, allowing the neck 10 to withstand greater external forces. In the event of a collision or vibration, the bottom shell 28 and the top shell 42 are less likely to separate, thus ensuring the overall structural stability of the neck 10 and helping to maintain the normal operating condition of the electronic musical instrument 100.
[0091] Furthermore, the first connecting hole 50 and the second connecting hole 52 provide precise positioning for the installation of the front shell 42 and the bottom shell 28. During installation, by sequentially passing fasteners through the first connecting hole 50 and the second connecting hole 52, it can be ensured that the front shell 42 and the bottom shell 28 are accurately installed in the appropriate positions, avoiding misalignment or displacement, thereby ensuring the relative positional accuracy of the various structural parts of the neck 10. This reduces installation difficulty and improves installation efficiency.
[0092] Furthermore, the fasteners securely connect the bottom shell 28 and the top shell 42, allowing for easy assembly and disassembly. When internal components of the neck 10 require repair, replacement, or cleaning, simply removing the fasteners allows for easy separation of the top shell 42 and bottom shell 28, enabling access to the interior of the neck 10. This detachable connection method enhances the maintainability of the electronic musical instrument 100, reducing repair costs and complexity.
[0093] In one embodiment, the periphery of the front shell 42 and the bottom shell 28 of the neck 10 is provided with a slot and a buckle, respectively. A first connecting hole 50 and a second connecting hole 52 are opened in the space-constrained area. In the illustrated embodiment, the front shell 42 and the bottom shell 28 are each provided with three connecting holes. They are connected by the slots, buckles, and three fasteners. This can improve the reliability of the connection between the bottom shell 28 and the front shell 42, and simplify the positioning and installation process, reduce the number of installation steps, and help improve the installation quality and efficiency.
[0094] In summary, by optimizing the light-incident surface 22 of the light guide 16, the number of required light sources can be reduced, achieving essentially the same effect with fewer light sources. This optimizes the internal layout of the neck 10, and the reduced number of light sources also reduces installation steps and costs. Furthermore, by assembling and fixing the light guide post with the front shell 42 and the bottom shell 28 of the neck 10, the light guide 16 can be fully positioned, ensuring the stability and reliability of its installation. Finally, the front shell 42 and the bottom shell 28 of the neck 10 are fixedly connected by slots and clips, and secured with three screws, reducing the number of screws, thereby reducing assembly steps, improving assembly efficiency, and lowering production costs.
[0095] Please see Figure 1 The present invention provides an electronic musical instrument 100, which includes the neck 10 of any of the above embodiments.
[0096] In the aforementioned electronic musical instrument 100, the light-incident section 20 is configured to convert the light emitted from the light source into parallel light rays that propagate within the light guide 16. This enables the light guide 16 to achieve a uniform light guiding effect, thereby reducing the number of light sources, which helps to reduce space occupation and lower costs.
[0097] Specifically, electronic musical instruments 100 include, but are not limited to, electronic guitars, electronic pipa, electronic liuqin, electronic yueqin, electronic pianos, etc.
