TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent guitar, in particular to a single note playing method of intelligent guitar and the intelligent guitar. BACKGROUND

[0002] Guitar is a stringed musical instrument that produces sound by plucking the strings. The "product" in guitar is also called "grade" and "character", which is the basic position of the strings to produce different frequency sounds. When playing guitar, the performer presses different grades with one hand and plucks the strings with the other hand. Through the coordination of the two hands, the length of the vibrating strings is different, which in turn causes different frequencies of sound. This is the basic principle of guitar sound production. Currently, intelligent guitar has become a popular choice for music lovers and guitar learners. Intelligent guitar can display music scores and control playing rhythm through sensors and processors. However, the existing intelligent guitar is designed for beginners to learn chords by pressing keys and plectrums, but it does not have the function of single note playing, which is relatively single and not convenient for beginners to learn guitar. SUMMARY

[0003] The present application provides a single note playing method of intelligent guitar and the intelligent guitar to overcome the shortcomings of the prior art and achieve the single note playing mode.

[0004] To achieve the above purpose, the present application provides a single note playing method of intelligent guitar, comprising the following steps:

[0005] S1: The mobile terminal APP or cloud server sends a song data packet to the intelligent guitar through wireless communication;

[0006] S2: The intelligent guitar analyzes the data packet and lights up the backlight LED of the chord touch key in time sequence on the neck fretboard to guide the user to press the position with the left hand;

[0007] S3: The display screen or light guides the user to pluck the position with the right hand;

[0008] S4: After the user plucks the specified key according to the display screen or light prompt, the corresponding audio information in the data packet is triggered.

[0009] Further improvement of the above scheme is that the song data packet includes a single note light sequence, and the single note light sequence is the time sequence of chord touch key and single note module LED lighting according to the song progress.

[0010] Further improvement of the above scheme is that in step S3, only when the user correctly presses the chord touch key with the left hand, the light of the plectrum piece of the single note module is activated and lit.

[0011] A further improvement to the above solution is that in step S3, the light in the light-transmitting area flashes dynamically to indicate the time to dial the key:

[0012] Steady on means ready to be triggered;

[0013] 2Hz flashing means you need to dial within 0.5 seconds;

[0014] 5Hz fast flashing means the dial timing is wrong.

[0015] A further improvement to the above scheme is:

[0016] In step S3, when the right hand plucks the single-tone module, the smart guitar detects whether the pressure sensor sensing value of the left hand's corresponding chord touch key reaches a threshold;

[0017] If the standard is not met, it will be judged as an invalid single tone trigger, and the light in the light-transmitting area will switch to red as a warning.

[0018] A further improvement to the above scheme is:

[0019] In step S4, the single note signal is generated as follows:

[0020] The plucking intensity is detected by the pressure sensor and mapped to the note volume.

[0021] On the other hand, the present invention provides an intelligent guitar, which is applied with the above-mentioned single-note playing and singing method of an intelligent guitar, and includes a neck, a body, a processor, a display screen, a pressure sensor and a communication module;

[0024] Silicone base block;

[0025] Multiple independent plectrums protruding from the surface of the silicone base;

[0026] Each plectrum is equipped with a light-transmitting area and a corresponding LED light source at the bottom;

[0027] A pressure sensor is connected under each plectrum, and the pressure sensor is electrically connected to the processor;

[0028] The processor is used to dynamically analyze song data packets and independently control the on and off timing of the neck LED and the single tone module LED;

[0029] The communication module is used to receive song data packets from a mobile terminal APP or a cloud server, and the data output end of the communication module is communicatively connected to the data input end of the processor.

[0030] Further improvement of the above scheme is that the bottom of each chord region is provided with a pressure sensor.

[0031] Further improvement of the above scheme is that the string pressing pieces are arranged in long strips and uniformly, and the length of the string pressing pieces covers the projection area of 6 strings; the light transmission area is a top circular opening or a translucent silica gel window, and the center of the light transmission area is aligned with the string projection.

BRIEF DESCRIPTION OF DRAWINGS

[0034] Figure 1 The flowchart of the present application. DETAILED DESCRIPTION

[0035] The present application will be further described below in conjunction with the drawings. It should be understood that the specific embodiments described herein are intended to be illustrative only and not limiting of the present application. In addition, it should be noted that for the purpose of clarity, not all of the structures of the application are shown in the drawings.

[0036] Before some example embodiments are discussed in more detail, it should be noted that some example embodiments are described as processes or methods depicted as flowcharts. Although the processes are described in a particular, sequential order, many of the steps can be performed in parallel, in different orders, or concurrently. Further, an order that steps are described in should not be understood as a requirement that such steps be performed in that order. The processes can be terminated when their operations are completed, but the processes can also have additional steps not included in the figure(s) that can be performed after the processes have been completed. The processes can correspond to methods, functions, procedures, subroutines, and the like.

[0037] As shown in FIG. 1, Figure 1 The present application provides a single note strumming method of an intelligent guitar, comprising the following steps:

[0038] S1: The mobile terminal APP or cloud server sends the song data packet to the smart guitar through wireless communication;

[0039] S2: The smart guitar analyzes the data packet and illuminates the backlight LEDs of the chord touch buttons on the neck and fretboard in a timed sequence, guiding the user's left hand to press the buttons.

[0040] S3: Use the display or light to guide the user to move the dial position with their right hand;

[0041] S4: After the user presses the designated button according to the display screen or light prompt, the corresponding audio information in the data packet is triggered.

[0042] Specifically, wireless communication can be connected to a mobile terminal APP or cloud server wirelessly, such as Bluetooth 5.0: using the low-power protocol (BLE GATT), establishing a two-way data channel after pairing, and the transmission delay is less than 20ms; or using WIFI connection: creating an AP hotspot through the ESP32 module, allowing mobile terminal APP or cloud server to directly access, with a transmission bandwidth of ≥10Mbps; it can also be connected by wired means, directly connected through the Type-C or USB interface, with low transmission delay.

[0043] The song data packet includes a single-note light sequence, which is the lighting timing of the chord touch buttons and the single-note module LED according to the song progress. Specifically, the song data packet is a JSON structured data packet, which can include chord instructions: fret number, string position coordinates, RGB color value; the single-note sequence can include the string piece ID, trigger timestamp, and target note frequency. After the smart guitar parses the data packet, it adjusts the lighting timing according to the data in the data packet.

[0044] In step S3, the light in the light-transmitting area of ​​the plucking piece of the single-tone module will be activated and lit only when the user's left hand presses the chord touch button correctly. Specifically, when the user's left hand chord pressing is effective and the right hand plucks the correct target single-tone module plucking piece within 0.5 seconds, the light in the light-transmitting area of ​​the synchronous single-tone module plucking piece will light up. The two-handed collaborative verification mechanism can effectively avoid incorrect playing habits, correct the user's playing habits, and facilitate beginners to learn guitar.

[0045] In step S3, the light in the light-transmitting area flashes dynamically to indicate the time to turn the dial:

[0046] Steady on means ready to be triggered;

[0047] 2Hz flashing means you need to dial within 0.5 seconds;

[0048] 5Hz fast flashing means the dial timing is wrong.

[0049] Furthermore, the brightness of the light can be used for identification and differentiation. The high-brightness lamp beads (white / green) represent the operation that the current user needs to perform, and the low-brightness lamp beads represent the preview prompts of the next operation. The LED light color is used for identification and differentiation, guiding the user to play with both hands in coordination, which is convenient for beginners to learn guitar.

[0050] In step S3, when the right hand plucks the single-tone module, the smart guitar detects whether the pressure sensor sensing value of the left hand's corresponding chord touch key reaches a threshold. In this embodiment, the pressure sensor can be set to a commonly used piezoresistive sensor or capacitive sensor;

[0051] If the standard is not met, it will be judged as an invalid single-tone trigger, and the light in the light-transmitting area will switch to red warning. The threshold detection can prevent the user from accidentally touching the smart guitar when holding it, making it easy to use.

[0052] In step S4, the single note signal is generated as follows:

[0053] The plucking intensity is detected by a pressure sensor and mapped to the note volume. In this embodiment, the sensor is configured as a vibration sensor.

[0054] Another aspect of the present invention provides an intelligent guitar, which is applied with any of the above-mentioned single-note playing and singing methods of an intelligent guitar, and includes a neck, a body, a processor, a display screen, a pressure sensor, and a communication module;

[0055] The neck fingerboard is equipped with multiple groups of LED backlit chord touch buttons, each group of buttons corresponds to a chord area;

[0056] The surface of the guitar body is equipped with a single-tone module, which includes:

[0057] Silicone base block;

[0058] Multiple independent plectrums protruding from the surface of the silicone base;

[0059] Each plectrum is equipped with a light-transmitting area and a corresponding LED light source at the bottom;

[0060] A pressure sensor is connected under each plucking piece, and the pressure sensor is electrically connected to the processor. In this embodiment, the pressure sensor is configured as a piezoresistive thin film sensor with a small thickness, which can ensure the authentic plucking feel of the plucking piece. At the same time, the piezoresistive thin film sensor can monitor the force distribution in real time. Combined with the contact center of gravity of the user's finger when plucking the string, it can distinguish whether the user is plucking up or sweeping down. When it is pressed, the contact area of ​​the internal conductive network changes, thereby realizing the conversion of the pressing force into an electrical signal with a resistance change. The processor can add playing technique sound effects (such as strumming noise, nail touching string sound, etc.) according to different actions, and can also cooperate with the string touch button to perform two-hand coordinated detection to avoid incorrect playing habits.

[0061] The processor is used to dynamically analyze song data packets and independently control the on and off timing of the neck LED and the single tone module LED;

[0062] The communication module is used to receive song data packets from the mobile terminal APP or the cloud server, and the data output end of the communication module is communicatively connected to the data input end of the processor.

[0063] A pressure sensor is provided at the bottom of each chord area. In this embodiment, the pressure sensor is configured as a piezoresistive sensor.

[0064] The plectrums are evenly arranged in long strips, and the length of the plectrums covers the projection area of ​​6 strings; the light-transmitting area is a circular opening on the top or a translucent silicone window, and the center of the light-transmitting area is aligned with the projection of the strings. The plectrums correspond to the projection area of ​​the strings, which is in line with the playing habits of traditional guitar and can effectively help beginners form correct playing habits.

[0065] Working Principle: Taking the single-note singing process of "Twinkle Twinkle Little Star" as an example, the user operates the mobile terminal APP or obtains the song data packet from the cloud server. The mobile terminal APP or cloud server caches the song data packet to the smart guitar via wired or wireless communication. The processor parses the song data packet and drives the LED backlight under the corresponding fret of the chord touch button on the neck according to the content of the song data packet. At this time, the piezoresistive sensor under the chord touch button is monitored in real time. When the processor detects that the capacitor sensor data meets the valid press judgment condition, that is, the piezoresistive sensor sensing value reaches the threshold (such as when the capacitance value ≥ 50pF), the LED backlight at the bottom of the chord touch button lights up. At this time, the processor controls the corresponding indicator light in the light-transmitting area of ​​the single-note module according to the data in the song data packet. When the user plucks the string piece in the corresponding light-transmitting area with his right hand, the pressure sensor outputs a voltage, which is mapped to the output volume level after ADC conversion and outputs the single-note playing sound. In this way, according to the song data packet, timely feedback and guidance are provided through light, replacing the display screen, effectively ensuring the user's concentration when using the smart guitar. At the same time, single-note singing can be achieved, which can help beginners familiarize themselves with guitar playing through the smart guitar.
