[0040] In order to illustrate the technical solution provided by this application, a detailed description is given below with reference to specific drawings and embodiments.

[0041] As shown in FIG. 1 to FIG. 4 , some embodiments of the present application provide a string instrument playing system 100, including:

[0042] A button module 110, wherein the button module 110 includes at least one button 111;

[0043] A tension adjustment module 120, which is connected to the strings and is used to adjust the tension of the strings;

[0044] A control module 140 , wherein the control module 140 is in communication with the button module 110 and the tension adjustment module 120 ;

[0045] The control module 140 responds to the operation of the button 111 and sends a control signal corresponding to the pressed button 111 to the tension adjustment module 120. The tension adjustment module 120 adjusts the tension of the corresponding string according to the received control signal.

[0046] String instruments produce sound through the vibration of their strings. Different frequencies of string vibration produce different sounds. When playing a string instrument, the strings are pressed to adjust their vibration length and tension. Different vibration lengths and tensions cause the strings to vibrate at different frequencies when plucked, producing different sounds.

[0047] In this embodiment, the key module 110 includes at least one key 111. The key module 110 can be a mechanical key 111, a touch key 111, an optical key, or other common physical or virtual key forms, which are not required herein. A trigger signal is generated by touching or pressing. Each key 111 corresponds to one trigger signal.

[0048] Mechanical buttons have a corresponding trigger mechanism under the button. One type is contact-type buttons, such as mechanical switches and conductive rubber switches; the other type is contactless buttons, such as electrical buttons and magnetic induction buttons. The former are low-cost, while the latter have a long lifespan.

[0049] In a touch button, each button (i.e., each pad) forms an inductive capacitance with the ground. Under constant ambient conditions, this capacitance remains constant and small. When a finger approaches the button, the capacitance between the finger and the ground forms a parallel connection with the capacitance between the pad and the ground, increasing the total capacitance. This change in capacitance triggers the button to issue a command.

[0050] Photoelectric buttons use the principle of light sensing to generate resistances of different values, forming two states: open circuit and open circuit, thereby triggering the button to send a signal instruction.

[0051] The tension adjustment module 120 is connected to the strings and adjusts the string tension. The tension adjustment module 120 can be a stretching mechanism that tightens or loosens the strings to adjust the string tension. For example, a motor, pneumatic cylinder, or hydraulic cylinder can tighten or loosen the strings through forward or reverse motion at the output end.

[0052] The tension adjustment module 120 can also be a raising or pressing mechanism that adjusts the string tension by partially raising or pressing the strings. For example, a scissor mechanism, a pneumatic or electric lifting device, etc., can be installed above or below the strings. The device can be raised or lowered to press or raise the strings, thereby tightening or loosening the strings.

[0053] The control module 140 is respectively connected to the button module 110 and the tension adjustment module 120 for communication, receives the trigger signal generated by the button module 110, and sends a control signal corresponding to the pressed button 111 to the tension adjustment module 120 based on the received trigger signal. The tension adjustment module 120 adjusts the tension of the corresponding string based on the received control signal.

[0054] The control module 120 may be a single chip microcomputer, a control module, or a control system, which is not limited here.

[0055] The trigger signal generated by a key corresponds to a musical tone identifier, and a musical tone identifier corresponds to a control signal for controlling the tension adjustment module 120 , that is, the trigger signal generated by a key corresponds to a control signal for controlling the tension adjustment module 120 .

[0056] Different control signals control the tension adjustment module 120 to adjust the string tension differently, causing the strings to vibrate at different frequencies and produce different sounds. A single control signal can control the tension adjustment module 120 to adjust the tension of a single string, so that plucking that string produces a single note. A single control signal can also control the tension adjustment module 120 to adjust the tension of several strings, so that plucking the corresponding strings produces a chord. A single control signal can also control the tension adjustment module 120 to sequentially adjust the tension of one or several strings, so that plucking the strings continuously produces a musical note.

[0057] Specifically, musical sounds include single notes and chords. A single note is a single note. A chord is composed of single notes, and a chord is usually composed of three or more single notes, which are played simultaneously or continuously according to a specific interval relationship. Common chord types include triads, tetrachords, and quintuplets. For example, the C major triad consists of three notes: C, E, and G; the Cmaj7 tetrachord consists of four notes: C, E, G, and B. Through the appropriate use of chords, we can create rich and colorful musical effects, adding a sense of layering and harmony to the music.

[0058] Correspondingly, the control signal includes a single-tone control signal and a chord control signal. A single-tone control signal controls the tension adjustment module to operate on a single string. A chord control signal contains multiple single-tone control signals corresponding to the chord, which can simultaneously control the tension adjustment module to operate on multiple corresponding strings.

[0059] The control parameters of the tension adjustment module controlled by a single tone control signal vary depending on the specific form of the tension adjustment module. For example, if the tension adjustment module is a pneumatic cylinder, the control parameters control the cylinder's expansion and contraction, thereby adjusting the string tension. If the tension adjustment module is a scissor mechanism, the control parameters control the distance between the two forks of the scissor mechanism, thereby adjusting the amount of lift of the scissor mechanism to change the string tension.

[0060] Specifically, for stringed instruments of the same model, the playing length, material, and diameter of the strings used are fixed. To play a target single note on one of the strings, the string tension is a fixed value. To achieve this value, the tension adjustment module is controlled to achieve the corresponding preset movement amount.

[0061] For example, if the tension adjustment module is a pneumatic cylinder, the string tension on the open first string of a certain guitar model is 7 kg. When the string tension reaches 8 kg, the open string produces an "F" note, and the string stretches by 0.5 mm. When the control module receives a trigger signal corresponding to the "F" note, it sends a control signal to the tension adjustment module, instructing the pneumatic cylinder connected to the first string to stretch the string by 0.5 mm. At this time, the open first string produces an "F" note.

[0062] This embodiment provides a button module 110, a tension adjustment module 120, and a control module 140. The tension adjustment module 120 is connected to the strings and is used to adjust the string tension. The control module 140 responds to the operation of the button 111 and controls the tension adjustment module 120 to adjust the string tension, thereby changing the string tension and the string vibration frequency, thereby making the strings produce the target musical sound.

[0063] To play a stringed instrument using the stringed instrument playing system 100 provided in this embodiment, one only needs to operate the key module 110 and then pluck the strings to play. It does not require a lot of practice, is easy to use, is very friendly to beginners, and is conducive to the popularization of stringed instruments.

[0064] In some embodiments, the method in which the control module 140 responds to the operation of the key module 110 includes:

[0065] The control module 140 obtains single tone identification information according to the identification information of the musical tone;

[0066] Determining a target string tension according to the correspondence between the single-note identification information and the string tension;

[0067] Control information is determined based on the target string tension.

[0068] The musical note identification information received by the control module 140 may be a single note identification information or a chord identification information composed of multiple single note identification information. If the musical note identification information received by the control module 140 is a single note identification information, the single note identification information is obtained. If the musical note identification information received by the control module 140 is a chord identification information, multiple single note identification information is obtained.

[0069] The sound of the strings is related to the string tension. Different string tensions will cause the strings to produce different sounds when in the open state.

[0070] Taking a guitar as an example, the tension adjustment module 140 is a tensioning device. The guitar capo is clamped at the third fret, and the string length is approximately 55mm. String 1 is the thinnest string, and string 6 is the thickest. The string tension is tested and adjusted to produce different musical notes when the strings are plucked open. The specific tension, corresponding musical notes, and corresponding string end displacement are shown in FIG6 .

[0071] To achieve different sounds when the strings are unstringed, the tension of the strings can be adjusted using a tension adjustment device. Each string's target musical sound is determined by a specific tension value. Each tension value corresponds to a specific amount of tension adjustment device movement. Control information is used to control the tension adjustment device to achieve this desired movement.

[0072] In some embodiments, as shown in FIG4 , the control module 140 includes a storage unit 141 ;

[0073] The storage unit 141 stores single-note identifiers or chord identifiers corresponding to the buttons 111;

[0074] The control module 140 matches the target identifier stored in the storage unit 141 according to the received key 111 signal, and determines the control signal to be sent to the tensioning force adjustment module 120 according to the target identifier.

[0075] Specifically, the control module 140 includes a storage unit 141, in which a single-note music identifier or a chord identifier is stored, and the single-note music identifier or the chord identifier corresponds to the button 111 one by one. A single-note music identifier or a chord identifier corresponds to a control signal, and the tension adjustment module 120 is controlled by the control signal to adjust so that when the string is open, the string can produce a musical sound that matches the preset single tone or chord. The single-note music identifier or the chord identifier stored in the storage unit 141 can be preset by the manufacturer, or the user can enter it into the storage unit 141 according to the performance requirements. The specific correspondence between the button 111 and the single-note music identifier or the chord identifier can be set according to the user's usage habits.

[0076] The control module 140 matches the received signal from the key 111 to the target identifier stored in the storage unit 141, and determines a control signal to be sent to the tension adjustment module 120 based on the target identifier. When any key 111 on the key module 110 is triggered, a trigger signal corresponding to that key 111 is transmitted to the control module 140. The control module 140 receives the trigger signal and matches it with the information stored in the storage unit 141 to find the single musical note identifier or chord identifier corresponding to that key 111. Based on the matched single musical note identifier or chord identifier, the control module 140 sends a control signal to the tension adjustment module 120, causing the tension adjustment module 120 to perform corresponding actions and adjust the string tension.

[0077] In some embodiments, as shown in FIG1 to FIG4 , the tension adjustment module 120 includes a connection unit 121 and a tension unit 122 ;

[0078] One end of the connecting unit 121 is connected to the strings, and the other end is connected to the tension unit 122;

[0079] The tension unit 122 adjusts the tension of the strings by adjusting the tension on the strings.

[0080] Specifically, the tension adjustment module 120 includes a connection unit 121 and a tension unit 122. The tension unit 122 is connected to the strings via the connection unit 121. The tension unit 122 is used to pull the strings. When the tension applied by the tension unit 122 to the strings increases, the string tension increases. When the tension applied by the tension unit 122 to the strings decreases, the string tension decreases. The tension applied to the strings is adjusted by adjusting the tension by the tension unit 122 to adjust the string tension.

[0081] The pulling force unit 122 may be a motor, a cylinder, a hydraulic cylinder, or other common equipment capable of providing pulling force, which is not limited here.

[0082] In some embodiments, as shown in FIG. 1 to FIG. 4 , the control signal is used to control the tension applied by the tension unit 122 to the strings.

[0083] In this embodiment, the tension of the strings is controlled by the tension unit 122. The magnitude of the tension applied to the strings by the tension unit 122 is proportional to the magnitude of the tension of the strings. The control module 140 sends a control signal to control the tension of the strings by the tension unit 122, thereby achieving the adjustment of the tension of the strings.

[0084] For example, when the string instrument playing system 100 is applied to a certain model of guitar, the capo is positioned at the third fret, the string length is approximately 55 mm, the first string is the thinnest, and the sixth string is the thickest. The string playing system 100 adjusts the string tension so that different musical notes can be produced by plucking the open string. The specific tension, corresponding musical notes, and corresponding string end displacement are shown in FIG6 .

[0085] The control signal controls the tension unit 122 to apply different tensions to the strings, thereby changing the tension of the strings, so that the strings produce different musical sounds.

[0086] In some embodiments, as shown in FIG5 , a force measuring device is provided at one end of the connecting unit 121 ;

[0087] The control module 140 is in communication with the force measuring device;

[0088] The control module 140 receives the data fed back by the force measuring device, compares it with the data preset in the control module 140 , and sends a control signal corresponding to the pressed button to the tensioning force adjustment module 120 based on the comparison result.

[0089] In this embodiment, the force measuring device is used to detect the magnitude of the force pulling the strings, and can specifically be a dynamometer, a force sensor, etc. The force measuring device can be provided at either end of the two connection ends of the connection unit 121, and can detect the tension of the strings.

[0090] The magnitude of the tension applied to the string is equal to the string tension. The force measuring device transmits the detected tension to the control module 140, which has preset values ​​for the string tension required to produce different musical notes. See the table in Figure 6 for details. The control module 140 compares the received feedback from the force measuring device with the preset data. If the data matches the preset data, the tension adjustment module 120 issues a signal indicating a standstill. If the data does not match the preset data, the tension adjustment module 120 issues an adjustment signal to adjust the string tension until the feedback data matches the preset data.

[0091] The control module 140 adjusts the control signal sent to the tension adjustment module 120 according to the feedback signal of the force measuring device, which can more accurately adjust the tension of the strings, so that the musical sound produced when playing the string instrument playing system is more accurate.

[0092] In some embodiments, the pulling unit 122 is a stepping motor, and the connecting unit 121 is connected to the power output end of the stepping motor;

[0093] The control signal is used to control the direction and number of steps of the stepping motor.

[0094] In this embodiment, the tension unit 122 is a stepper motor. A stepper motor is an electric motor that converts electrical pulse signals into corresponding angular or linear displacements. Each pulse signal causes the rotor to rotate one degree or advance one step. The output angular or linear displacement is proportional to the number of pulses input, and the rotational speed is proportional to the pulse frequency.

[0095] The connecting unit 121 is connected to the power output of the stepper motor, and the strings are connected to the power output of the stepper motor through the connecting unit 121. The control signal is used to control the direction and number of steps of the stepper motor, accurately controlling the feed amount to ensure accurate musical sound when used.

[0096] In some embodiments, the pulling unit 122 is a servo motor, and the connecting unit 121 is connected to the power output end of the servo motor;

[0097] The control signal is used to control the direction and angle of the servo motor.

[0098] In this embodiment, the pulling unit 122 is a servo motor. The servo motor can convert a voltage signal into torque and rotation speed to drive a controlled object, and the accuracy of controlling speed and position is very high.

[0099] The connecting unit 121 is connected to the power output end of the servo motor, and the strings are connected to the power output of the servo motor through the connecting unit 121. The control signal is used to control the direction and angle of the servo motor, and the control accuracy is high.

[0100] In some embodiments, as shown in FIG. 1 to FIG. 3 , the string instrument playing system 100 further includes a display panel 130 , which is connected to the control module.

[0101] Traditional stringed instruments rely on pressing the strings to adjust their vibration length and tension, thereby producing different sounds. Different strings are pressed at different locations to produce different sounds.

[0102] In this embodiment, the strings can be adjusted to produce different musical notes without pressing them. The target musical note is a single note, a chord, or a chordal section. The target musical note corresponds to the sound produced by pressing a string on a traditional string instrument that lacks a tension adjustment mechanism. To help the user understand the string position on a traditional string instrument that corresponds to the target musical note, a display panel 130 indicates the desired pressing position.

[0103] The tension adjusting mechanism adjusts the string tension so that it can produce the target musical sound in the open string state. The display panel 130 is used to display the string position that needs to be pressed down to produce the target sound or target chord in a traditional string instrument without a tension adjusting mechanism.

[0104] The display panel 130 can be a display screen or a display light panel composed of light beads. The display panel 130 can be set on the stringed instrument or at other locations that are convenient for the user to view.

[0105] Taking the guitar as an example, when the first string from the left is played open, the musical note is "E". When the first string from the left is pressed at the first fret on the fingerboard, the musical note is "F". The tension of the string is adjusted by the tension adjustment mechanism so that the musical note "F" is played when the string is played open. At this time, the display panel 130 shows that the position to be pressed is the first string from the left, pressed at the first fret.

[0106] The display panel 130 may display the pressed position with text, such as "third string, fourth fret", or may be provided with multiple groups of light beads corresponding to the pressed string positions. When the light beads light up, it indicates that the position is pressed, which is helpful for displaying the chords.

[0107] Specifically, when the stringed instrument is a guitar, six columns of light beads are set on the display panel 130, corresponding to the six strings of the guitar. Each column is provided with N light beads, representing the pressing positions from the first fret to the Nth fret.

[0108] Preferably, N can be 4. When playing the guitar, pressing the first to fourth frets can play most single notes and chords on a cost-effective basis.

[0109] In some embodiments, as shown in FIG1 , this embodiment provides a guitar, including the string instrument playing system 100 described in any of the above embodiments.

[0110] In this embodiment, the tension adjustment module 120 is connected to the guitar strings. The control module 140 responds to the operation of the key 111 and sends a control signal corresponding to the pressed key 111 to the tension adjustment module 120. The tension adjustment module 120 adjusts the tension of the corresponding guitar strings according to the received control signal.

[0111] In some embodiments, the button module 110 is disposed above the fingerboard.

[0112] In this embodiment, the button module 110 is arranged above the fingerboard. The user's posture when pressing the button module 110 is similar to that when actually pressing the strings. The operation feels stronger, the experience is good, and it is easy to get started.

[0113] The key module 100 may not be in contact with the strings. If the key module 100 is not in contact with the strings, the strings will not be affected, and the string positions not blocked by the key module 100 can be played normally.

[0114] The key module 100 can also come into contact with the strings, abutting the fingerboard and pressing the strings to prevent them from vibrating. The pressed portion of the string does not vibrate, effectively shortening the string's usable length. When the strings are tensioned to a certain tension value, the shorter the string's usable length, the smaller the adjustment amount by the tension adjustment module.

[0115] In some embodiments, the button module 110 can be set at at least one position on the side of the neck, the back of the neck, and the headstock. The button module 110 can also be set at other positions to suit the user's operating habits.

[0116] In some embodiments, the keys 111 are arranged in 6 columns along the string installation direction, and each column is provided with 4 keys 111.

[0117] Specifically, the keys 111 are arranged in 6 columns along the string installation direction, corresponding to the six strings of the guitar, and each column is provided with 4 keys, corresponding to the four frets of the guitar.

[0118] The key module 110 can be installed between the first and third frets of the guitar, between the first and fourth frets, or anywhere else convenient for the operator. The key module 110 is arranged in six columns and four rows, with a total of 24 operation keys 111. This allows the user to easily memorize the notes or chords corresponding to the keys 111. Furthermore, the key module 110 is compact and easy to operate.

[0119] The above are merely optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included within the scope of the claims of the present application.
