[0040] Embodiment 1

[0041] like Figures 1 to 5 As shown, this embodiment provides an input device 100 for a guitar controller, comprising:

[0042] At least one first sensor is arranged between the fingerboard and the strings, and one string corresponds to one first sensor 120 in one fret;

[0043] The input device is in communication connection with the guitar controller, and the trigger signal sent to the guitar controller by each first sensor 120 when triggered corresponds to a single note or a chord;

[0044] Wherein, the first sensor is a touch sensor or a photoelectric detection device.

[0045] In this embodiment, at least one first sensor 120 is disposed between the fingerboard and the strings. Specifically, the first sensor 120 can be disposed on the bottom plate 110 and installed between the fingerboard and the strings through the bottom plate 110, or can be directly disposed on the fingerboard and placed between the fingerboard and the strings, or can be installed in other ways. The first sensor 120 is used to sense the user's fingers. When the user's fingers are in the sensing area of ​​the first sensor 120, a trigger signal can be issued. One first sensor 120 corresponds to one trigger signal, and one trigger signal corresponds to one musical sound, and the musical sound includes a single tone and a chord.

[0046] The first sensor may be a touch sensor, which is a sensor for detecting and responding to human body, and allows the user to interact with the device through touch. The first sensor 120 may specifically be a capacitive touch sensor, which is based on the principle of capacitance and senses touch operation by detecting the capacitance change of the touch area. Common capacitive touch sensors include capacitive touch screens and capacitive touch pads. It may also be a resistive touch sensor, which is based on the principle of resistance and senses touch operation by placing two layers of thin films with conductive coatings on the surface of the screen to generate resistance changes when touched. Resistive touch screens were more common in the past, but have now been replaced by other technologies. It may also be other common sensors that are triggered by touch. The development of touch sensors makes human-computer interaction more intuitive and natural, and is widely used in devices such as smart phones, tablet computers, computers, ATM machines, interactive displays, etc. It provides users with a more convenient and efficient way of operation and changes the way people interact with electronic devices.

[0047] The first sensor may also be a photoelectric detection device, which can be triggered when the user's finger moves to the sensing area of ​​the first sensor 120, and the response is more sensitive.

[0048] Specifically, the corresponding relationship between the trigger signal and the musical sound can be that the signal triggered by each first sensor 120 can uniquely identify the position of the key on the keyboard, and the signal has a unique corresponding relationship with the musical sound. For example, the multiple first sensors 120 are arranged in a 6×4 matrix, and the signal triggered by the sensor in the 1st row and 1st column is identified by a position identifier corresponding to the 1st row and 1st column, and the position identifier corresponds to a musical sound C, the signal triggered by the sensor in the 1st row and 2nd column is identified by a position identifier corresponding to the 1st row and 2nd column, and the position identifier corresponds to a musical sound D... The signal triggered by the sensor in the 3rd row and 6th column is identified by a position identifier corresponding to the 3rd row and 6th column, and the position identifier corresponds to a musical sound G, and so on.

[0049] The corresponding relationship between the trigger signal and the musical sound can also be that each first sensor 120 is connected to the controller separately, and each first sensor 120 corresponds to a musical sound. For example, the first sensor 120 No. 1 corresponds to a musical sound C, the first sensor 120 No. 2 corresponds to a musical sound D... The first sensor No. 6 corresponds to a musical sound G.

[0050] String instruments produce sound through the vibration of the strings. Different frequencies of string vibration produce different sounds. When playing a string instrument, the strings are pressed to adjust the vibration length and tension of the strings. Different vibration lengths and tensions of the strings cause the strings to vibrate at different frequencies when they are plucked, thus producing different sounds.

[0051] The string instrument playing system is provided with a tension adjusting device, which is connected to the strings and is used to control the tension of the strings. The tension of the strings is adjusted by the tension adjusting device, thereby changing the vibration frequency of the strings, so that the target single tone or target chord can be played when the open strings are plucked.

[0052] The tensioning force adjusting device is connected to the controller for communication, and the controller sends a control signal to the tensioning force adjusting device to control the tensioning force adjusting device.

[0053] The first sensor 120 is in communication connection with the controller, and the controller sends different control signals to adjust the tension of the strings according to different trigger signals received.

[0054] One trigger signal corresponds to one control signal. Different control signals control the tension adjusting device to adjust the tension of the strings differently, so that the strings can vibrate at different frequencies and produce different sounds. One control signal can control the tension adjusting device to adjust the tension of a certain string, so that a single tone can be played by plucking the string. One control signal can also control the tension adjusting device to adjust the tension of several strings, so that a chord can be played by plucking the corresponding strings. One control signal can also control the tension adjusting device to adjust the tension of one or several strings in sequence, so that a piece of music can be played by plucking the strings continuously.

[0055] Specifically, musical sounds include single tones and chords. A single tone is a single note. A chord is composed of single tones. A chord is usually composed of three or more single tones. These single tones 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 is composed of three notes: C, E, and G; the Cmaj7 tetrachord is composed of four notes: C, E, G, and B. Through the reasonable use of chords, you can create a variety of musical effects and increase the sense of hierarchy and harmony of the music.

[0056] It is understandable that the ukulele is also called a "four-string guitar". The structure of the ukulele is the same as that of the guitar, except that the size and number of strings are different. The "guitar" in this embodiment can be an ordinary six-string guitar or a ukulele.

[0057] In this embodiment, at least one first sensor 120 is arranged between the guitar fingerboard and the strings, and one first sensor 120 corresponds to one string in one fret. When the player presses the string, the first sensor 120 corresponding to the string is triggered at the same time, and a trigger signal is sent to the guitar controller. The trigger signal sent when a first sensor 120 is triggered corresponds to a single tone or chord. The user can conveniently send a command to the controller to change the single tone or chord by touching the button, and further conveniently control the tension adjustment device to adjust the tension of the string, which is convenient for the user to operate. By pressing the string to trigger the corresponding first sensor 120, the touch is close to that of playing the guitar in real life, which optimizes the player's experience.

[0058] Embodiment 2

[0059] On the basis of the first embodiment, the input device of the guitar controller further includes a bottom plate 110 , the first sensor 120 is mounted on the bottom plate 110 , and the bottom plate 110 is arranged on the fingerboard.

[0060] A plurality of first sensors 120 may be installed on the bottom plate 110, and then the bottom plate 110 may be installed on the fingerboard, which is more convenient for installation. The bottom plate 110 is arranged between the fingerboard and the strings, and the thickness of the bottom plate 110 is less than the distance between the fingerboard and the strings. The bottom plate 110 is arranged on the fingerboard, and the bottom plate 110 and the fingerboard may be bonded or connected in other common ways, and the fingerboard provides support for the bottom plate 110.

[0061] In one embodiment, the bottom plate 110 is detachably connected to the fingerboard, so as to facilitate installation or removal of the input device of the guitar controller and the fingerboard, and the guitar can be played normally after the input device of the guitar controller is removed.

[0062] Embodiment 3

[0063] On the basis of the first embodiment, a bottom plate is further included. The first sensor 120 is installed on the bottom plate 110 . The bottom plate 110 is arranged at the connection between the fingerboard and the neck.

[0064] A plurality of first sensors 120 can be installed on the bottom plate 110, and the bottom plate 110 provides support for the plurality of first sensors 120, which is more convenient for installation. The bottom plate is fixed between the fingerboard and the neck, and a clearance groove is provided on the neck, and the clearance groove is used to clear the first sensor 120 on the bottom plate, so that the first sensor 120 can pass through the fingerboard and be placed between the fingerboard and the strings. The installation of the bottom plate is more stable, and the input device of the guitar controller installed on the guitar is more beautiful.

[0065] Specifically, a plurality of slots may be provided to correspond to the position of each first sensor 120 .

[0066] Embodiment 4

[0067] On the basis of the third embodiment, the first sensor 120 is a touch switch, and the touch switch is arranged on the side of the corresponding string.

[0068] In this embodiment, the first sensor 120 is a touch switch, which includes a sensing area. When the sensing area is touched, the touch switch is turned on (or off), and when the touch stops, the touch switch is turned off (or on).

[0069] The touch switch is set on the side of the corresponding string. When the player presses the string, the touch switch corresponding to the string will be touched at the same time, thereby changing the switch state of the touch switch and sending a trigger signal to the guitar controller. The trigger switch is set on the side of the string to prevent accidental triggering of the trigger switch on different frets corresponding to the same string when pressing the string.

[0070] Embodiment 5

[0071] On the basis of the fifth embodiment, the touch switch is in the shape of a long strip, the length of the touch switch is less than the length of one fret on the fingerboard, and the width is less than 1 / 2 of the distance between two adjacent strings.

[0072] Specifically, the length of the touch switch is smaller than the length of one fret on the fingerboard to ensure that one touch switch can be set within one fret, and the width of the touch switch is smaller than 1 / 2 of the distance between two adjacent strings to avoid accidental touching of the first touch switch corresponding to an adjacent string when pressing a certain string.

[0073] Embodiment 6

[0074] On the basis of the first embodiment, the touch switch is embedded on the bottom plate 110, and the sensing area of ​​the touch switch is lower than the side of the bottom plate 110 that contacts the strings.

[0075] In this embodiment, the strings are in contact with the bottom plate 110. If the sensing area of ​​the touch switch is higher than or horizontal to the side of the bottom plate 110 that is in contact with the strings, it is easy to cause accidental touch due to the movement of the strings along the bottom plate 110. If the sensing area of ​​the touch switch is lower than the side of the bottom plate 110 that is in contact with the strings, the touch switch will only be triggered by pressing the strings, reducing the possibility of accidental touch.

[0076] After being pressed by the string pressing plate 134, the vibration of the strings on both sides of the string pressing plate will be blocked by the string pressing plate, that is, when the strings are plucked on one side of the string pressing plate 134, the strings on the other side of the string pressing plate 134 will not vibrate, which is equivalent to shortening the use length of the strings. When the strings are tensioned to a certain tension value, the shorter the use length of the strings, the smaller the adjustment amount of the tension adjustment device.

[0077] Embodiment 7

[0078] like Figure 3 As shown, based on the first embodiment, the first sensors 120 are distributed in an array, and the array is provided with 6 columns along the arrangement direction of the strings.

[0079] Specifically, the input device of the guitar controller is applied to a six-string guitar, and the first sensors 120 are arranged in six rows along the arrangement direction of the six strings, corresponding to the six strings respectively.

[0080] Preferably, the first sensors 120 are arranged in six columns and three rows, corresponding to the three frets of the guitar.

[0081] In one embodiment, the first sensor 120 can be installed at positions corresponding to the first to fourth frets of the guitar. The first sensors 120 are arranged in 6 columns and 3 rows, and a total of 18 first sensors 120 are operated, so that the user can memorize the single note or chord corresponding to the first sensor 120, which is convenient for the operator to operate.

[0082] In another embodiment, when the input device of the guitar controller is applied to a ukulele, the first sensors 120 are arranged in four rows along the arrangement direction of the four strings, corresponding to the four strings. The number of the first sensors 120 corresponds to the number of guitar strings.

[0083] Embodiment 8

[0084] like Figure 4 As shown, based on the first embodiment, the input device of the guitar controller further includes at least one auxiliary board 140:

[0085] at least one second sensor 150 disposed on the auxiliary plate 140;

[0086] The auxiliary plate 140 is disposed at at least one position on the side surface of the neck, the back surface of the neck, and the headstock.

[0087] In this embodiment, the second sensor 150 is mounted on the auxiliary board 140 to sense the touch of the user's finger. When the user's finger touches the second sensor 150, a trigger signal is sent. One second sensor 150 corresponds to one trigger signal, and one trigger signal corresponds to one musical sound.

[0088] The beneficial effects of the second sensor 150 of this embodiment are equivalent to the beneficial effects of the first sensor 120 described above, and are not described in detail here.

[0089] Embodiment 9

[0090] like Figure 5 As shown, this embodiment provides a guitar, comprising the input device of any one of the guitar controllers of Embodiments 1 to 9 and a capo 300;

[0091] The capo 300 is clamped between the bottom plate 110 and the piano body.

[0092] Specifically, a guitar includes a headstock, a neck and a body, wherein the neck is arranged between the headstock and the body, and the strings are arranged to extend from the headstock to the body. A sound hole is arranged on the body, and the string vibrates and produces sound when the string is plucked at the sound hole. The sound is transmitted into the body through the sound hole, resonates, amplifies the sound and modifies the timbre.

[0093] After the capo 300 is clamped, the strings on both sides of the capo 300, which are close to the sound hole, vibrate when the strings are plucked, while the strings on the side away from the sound hole do not vibrate when the strings are plucked. The capo 300 is clamped between the base plate 110 and the body of the qin, and the use length of the strings is shortened, which is conducive to reducing the adjustment amount of the tensioning force adjusting device. Pressing the strings in the area provided on the base plate 110 will not have any effect on the strings that can vibrate. After the capo 300 is clamped, the strings fit with the base plate 110, so that the fingers can accurately touch the corresponding first sensor 120 when pressing the strings.

[0094] In this embodiment, the guitar is preset with a tension adjusting device and a controller for controlling the tension adjusting device.
