Description

Technical Field

[0001] This invention relates to the field of finger sleeves, specifically a finger sleeve for playing stringed instruments. Background Technology

[0002] Stringed instruments produce sound by mechanically vibrating taut strings, thus limiting the volume of their sound. Different strings are typically used to play different notes, and sometimes the strings are pressed with the fingers to change their length, thereby altering the pitch.

[0003] Among stringed instruments, plucked instruments are the most difficult to learn because they require the use of a third medium, most commonly a pick. Playing with a pick requires mastering this medium to control the plucking force, which is quite challenging and difficult to control precisely. Furthermore, the pick doesn't provide a good grasp of tone quality, and the lack of precise perception at each angle requires considerable experience to compensate for, undoubtedly increasing the learning difficulty. While plucking directly with your fingers is better, the sharp strings can easily injure your fingers.

[0004] Finger sleeves, as a later-developed third-party medium, can be worn on the fingers for playing. However, finger sleeves have a certain thickness and are placed between the fingers and the strings, which can affect the hand's perception. Moreover, finger sleeves of different thicknesses will create different perceptions, making it difficult to control the tone and playing force, and resulting in poor tone quality during playing.

[0005] Furthermore, the outer side of the existing finger sleeves is smooth, which can cause the strings to slip when playing. Summary of the Invention

[0006] The purpose of this invention is to provide a finger sleeve for playing stringed instruments, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a finger sleeve for playing stringed instruments, including a thumb sleeve, wherein a protruding corner is fixedly installed on the top edge of the thumb sleeve, and an eight-shaped protrusion is provided on the outer side of the thumb sleeve that contacts the fingerprint; an eight-shaped protrusion is also provided on the outer side of the thumb sleeve that contacts the nail.

[0008] The hardness of the convex corner is greater than that of the thumb cot.

[0009] The side of the thumb sleeve that contacts the convex corner gradually hardens outwards, reaching its maximum hardness at the convex corner.

[0010] Preferably, it also includes other finger cots, with a strip-shaped protrusion on the outer side of the finger cot that contacts the thread.

[0011] The hardness of the strip-shaped protrusions is greater than that of the finger cot.

[0012] The area where the finger cot contacts the strip-shaped protrusion gradually hardens outwards, reaching its maximum hardness at the top of the protrusion.

[0013] Preferably, both the thumb cot and the finger cot have an opening on the side that contacts the fingernail.

[0014] Preferably, the vent is located on the side that comes into contact with the fingerprint.

[0015] Preferably, the ventilation holes on the thumb cot are distributed in a triangular pattern.

[0016] Preferably, the ventilation holes on the finger sleeve are linearly distributed and arranged parallel to the strip-shaped protrusions.

[0017] Preferably, the thumb cot and the finger cot have a recessed hole on the side that contacts the nail.

[0018] A method for manufacturing a finger sleeve for playing stringed instruments involves using the aforementioned finger sleeve for playing stringed instruments. After the finger sleeve is injection molded from silicone, a layer of cross-linking agent is applied to the convex corner of the thumb finger sleeve or the strip-shaped protrusion of the finger finger sleeve. Then, the thumb finger sleeve or finger finger sleeve is placed in an insulated box for heating for 1-2 hours, with the temperature of the insulated box maintained at 100-150℃.

[0019] A method for manufacturing a finger sleeve for playing stringed instruments involves using the aforementioned finger sleeve for playing stringed instruments. During injection molding of the finger sleeve, white and black charcoal (i.e., colored powdered X-ray amorphous silica and silicate products) is applied to the grooves of the protruding corners or the grooves of the strip-shaped protrusions in the mold. During injection molding, the white and black charcoal will mix in the protruding corners or the strip-shaped protrusions of the finger sleeve. Then, the finger sleeve is heated for 0-2 hours.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention features raised corners or strip-shaped protrusions made of a relatively hard material, with the hard parts directly contacting the fingers. When playing, the finger sleeve directly transmits the string's contact force to the fingers, allowing for direct tactile perception. This improves pitch control, facilitates smoother instrument learning, and provides more timely and accurate control of tone and melody. It avoids the instability in dynamics and tone control caused by the finger sleeve, and offers greater control over dynamics compared to using a pick. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-2 This embodiment provides a finger sleeve for playing stringed instruments, including a thumb sleeve 1. A protruding corner 2 is fixedly installed on the top edge of the thumb sleeve 1. An eight-shaped protrusion 4 is provided on the outer side of the thumb sleeve 1 that contacts the fingerprint of the finger. An eight-shaped protrusion 4 is also provided on the outer side of the thumb sleeve 1 that contacts the nail. The sides of the protrusions 4 that are close to each other are arc-shaped and have a certain curvature.

[0029] When the thumb plucks the string, the protruding corner 2 comes into contact with the string, causing the string to vibrate and produce sound.

[0030] Because it's related to the string's cut angle, the curvature of the contact surface between the finger and the string is also relevant. The curvature ranges from 15 degrees to 45 degrees. The finger is at its lowest point when in contact with the string, and as you play, you gradually pull upwards until the string reaches its highest point, then release to produce sound.

[0031] Furthermore, because the material of protrusion 4 is relatively hard, when it comes into contact with the strings, it will provide a reaction force to the strings under the tension of the strings. Therefore, when it comes into contact with the strings, it is a hard contact. Compared with the soft contact between the fingers and the strings, it can make the strings more taut and produce better sound quality.

[0032] Furthermore, when playing with the thumb, the string reaches its highest point, resulting in more even tension on the string. When the string is released, it produces a sound, preventing the string from vibrating during outward plucking and thus improving the sound quality.

[0033] Furthermore, the contact point between the figure-eight protrusion 4 and the string is at the tangent of the figure-eight arc. When the string detaches from the protrusion 4, it avoids collisions and interference with the string due to excessive contact, ensuring that there is no noise when the string is open.

[0034] When plucking the strings, make contact between the curved part of protrusion 4 and the string, push the lower part of your hand upwards, raise it to the highest point and tighten the string, and then release the string to produce a sound. With the curve, the pushing action does not need to be too big or the angle change does not need to be large. The finger sleeve can easily complete the high note action.

[0035] The raised design allows the fingers to produce sound with consistent force, requiring minimal effort to pluck the strings. This makes it easy to achieve the necessary elasticity while avoiding direct contact between the fingers and strings, thus reducing the difficulty for the hands. The raised design also prevents the strings from slipping during plucking.

[0036] The hardness of the protruding corner 2 is greater than that of the thumb sleeve 1. The side of the thumb sleeve 1 that contacts the protruding corner 2 gradually hardens outwards, reaching its maximum hardness at the protruding corner 2. The hardness of the protruding corner 2 extends directly to the inner wall of the finger sleeve, allowing the force from the protruding corner 2 to be directly transmitted to the finger without any obstruction, thus improving the finger's perception of force and enhancing finger sensitivity. When plucking the strings, there will be minimal variation in force, as the force can be directly transmitted to the finger through the combination of soft and hard elements.

[0037] like Figure 3-4 As shown, the finger sleeve also includes other finger sleeves 6, and the outer side of the finger sleeve 6 that contacts the thread has a strip-shaped protrusion 7.

[0038] The hardness of the strip-shaped protrusion 7 is greater than that of the finger sleeve 6. The area of ​​the strip-shaped protrusion 7 that comes into contact with the skin gradually hardens outwards, reaching its maximum hardness at the top. Located at the fingerprint and fingertip, the hardness of the strip-shaped protrusion 7 extends directly to the inner wall of the finger sleeve, allowing the force applied to it to be directly transmitted to the finger without any obstruction, thus enhancing the finger's perception of force. For example, when playing the guzheng, the strip-shaped protrusion 7 contacts the strings to pluck them, and the force applied to plucking the strings can be transmitted to the finger through the strip-shaped protrusion 7, improving the finger's perception of force.

[0039] Compared to a pick, which is a relatively hard medium and reduces the sensitivity of the hand, the fingertip provides a more stable contact area compared to the feel of a finger touching the notes. The raised corners (2 and 4) distribute the force to each fingertip, resulting in very timely feedback for each note. This improves sound control, making learning the instrument smoother and allowing for a more immediate and fluid grasp of tone and melody.

[0040] When playing the guzheng or other stringed instruments, the thumb is often used to pluck the strings. For example, when playing the pipa or guzheng, the thumb is used to pluck the strings back and forth. When the thumb plucks the strings back and forth, the protruding corner 2 will contact the strings, thus plucking the strings back and forth and making them produce sound.

[0041] Both the thumb sleeve 1 and the finger sleeve 6 have an opening 3 on the side that contacts the fingernail. This opening saves material during injection molding and allows for ventilation. The opening 3 is for placing the fingernail, which can pass through it, preventing damage to the finger sleeve and avoiding any discomfort caused by the finger sleeve pressing on the fingernail.

[0042] Both the thumb sleeve 1 and the finger sleeve 6 have ventilation holes 5. The ventilation holes are used to allow air to pass through and to dissipate moisture generated by the fingers.

[0043] Preferably, the ventilation holes 5 on the thumb sleeve 1 are triangularly distributed and located at the center of the thumb sleeve 1. The ventilation holes 5 on the finger sleeve 6 are linearly distributed and arranged parallel to the strip protrusion 7, and are distributed on both sides of the strip protrusion.

[0044] The thumb sleeve 1 and the finger sleeve 6 have a recess 8 on the side that contacts the nail. During injection molding, the recess 8 saves material and allows for ventilation. Furthermore, the recess 8 is located at the base of the nail where it contacts the finger, an area prone to peeling (hangnails) when subjected to friction. When plucking strings, the force required creates friction in this area. Therefore, the recess 8 design avoids this friction, preventing hangnails and providing better protection for the fingers.

[0045] A method for manufacturing finger sleeves for stringed instruments involves molding the finger sleeves with silicone, and then applying a layer of crosslinking agent to the protruding corner 2 of the thumb finger sleeve 1 or the strip-shaped protrusion 7 of the finger finger sleeve 6. The crosslinking agent can be a sulfur-containing crosslinking agent, such as sulfur, or it can be selenium.

[0046] Then place the thumb cot 1 or finger cot 6 in an incubator for 1-2 hours, maintaining the temperature of the incubator at 100-150℃.

[0047] Secondary vulcanization is performed on the convex corner 2 or strip protrusion 7 of the silicone rubber. When silicone rubber is vulcanized with peroxide, the decomposition of the peroxide triggers a polymer reaction, generating low-molecular-weight compounds such as benzene and benzoic acid, which will affect the mechanical properties of the rubber. Moreover, after the first stage of heating and molding, the cross-linking density of the silicone rubber is insufficient, and further vulcanization is required to increase the density of the silicone rubber. Tensile strength, resilience, hardness, swelling degree, density, and thermal stability are all significantly improved compared to single vulcanization. As the degree of rubber vulcanization increases, the outermost silicone rubber, which has the most contact with the vulcanizing agent, has the greatest hardness. As the rubber moves inward, the amount of vulcanizing agent gradually decreases, and the hardness slowly decreases, thus forming a soft-hard bond.

[0048] When treating the localized hardness of finger cots, black and white charcoal can also be used. During injection molding of the finger cot, black and white charcoal (i.e., colored powdered X-ray amorphous silica and silicate products) is applied to the grooves of the protruding corner 2 or the strip-shaped protrusion 7 in the mold. When injecting hot silicone, the flowing hot silicone flows into the grooves of the protruding corner or the strip-shaped protrusion in the mold and mixes with the black and white charcoal. The black and white charcoal will mix at the protruding corner 2 or the strip-shaped protrusion 7 of the finger cot, causing the protruding corner 2 or the strip-shaped protrusion to harden. The finger cot is then ready for direct use. However, the quality of the protruding corner 2 or the strip-shaped protrusion 7 may be unstable.

[0049] To improve the stability of the protruding corners or strip-shaped protrusions, the finger cots are heated for 0-2 hours, maintaining a temperature of 150-180℃, with a preferred treatment time of 1 hour at 170℃. This second heating of the finger cots softens the silicone again, allowing the carbon black and white charcoal to mix better with the silicone, thus improving the stability of the protruding corners 2 or strip-shaped protrusions 7.

[0050] To better fit the finger joints, the upper part of the finger sleeve (the back of the hand where the finger joint is located) is longer than the bottom part (the palm of the hand where the finger joint is located), ensuring flexible use of the joints when the fingers are clenched together or when playing.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
