Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of smart guitars, and in particular to a smart guitar based on a virtual string fretboard. Background Art

[0002] Smart guitars can simulate the sound and playing effects of traditional guitars through digital technology, but some technical sounds that can be achieved on traditional guitars, such as the push and rub string function, will be difficult to achieve on smart guitars. Currently, smart guitars can be divided into two types: those with strings on the fingerboard and those without strings on the fingerboard. Among them, the smart guitar with strings on the fingerboard places a coil at the end of the real strings, and analyzes and identifies the push and rub string action to make sounds by detecting the weak electrical signal changes caused by cutting the magnetic flux lines when the coil vibrates. However, beginners usually need a lot of practice when learning technical sounds. Using a smart guitar with strings on the fingerboard will cause pain during the push and rub string process, which is relatively unsuitable for beginners to learn, and the smart guitar with strings on the fingerboard also increases the difficulty of maintenance for users. However, the existing smart guitars without strings on the fingerboard are difficult to recognize technical sounds such as push and rub strings due to the lack of operation on real strings, which greatly affects the user experience. Summary of the invention

[0003] The embodiment of the present invention provides an intelligent guitar based on a virtual string fingerboard to solve the problem that the existing intelligent guitar without strings on the fingerboard cannot recognize technical sounds such as pushing and rubbing the strings, while avoiding the pain caused by traditional real pushing and rubbing methods.

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0026] Embodiment 1

[0027] Figure 1 This is a schematic diagram of the structure of a smart guitar based on a virtual string fretboard provided in the first embodiment of the present invention. This embodiment is applicable to the case where a smart guitar based on a virtual string fretboard is used to implement traditional complex and varied playing techniques such as pushing and rubbing the strings. Figure 1 As shown, the smart guitar includes: a motion detection module 100 and a data processing module 200; wherein the motion detection module 100 is used to obtain the motion data of the guitar fingerboard in real time, and transmit the motion data to the data processing module 200; the data processing module 200 is used to identify the string bending action and / or the string vibrato action according to the motion data.

[0028] Specifically, the structure of the smart guitar may include a neck and a body, and the neck may include a fingerboard. A virtual string fingerboard is a fingerboard without real strings. The fingerboard can simulate the strings and frets of a traditional guitar and set corresponding sensors to capture the user's string-pressing action. A motion detection module 100 is provided in the smart guitar, which can detect the motion data of the guitar fingerboard in real time. The motion data can reflect the slight vibration and tilt change of the guitar fingerboard, etc. Optionally, the motion data includes at least one of posture data, acceleration data and angular velocity data. Optionally, the motion detection module 100 is provided on the guitar fingerboard. Since the movement amplitude of the guitar neck is more obvious than that of the guitar body when the user performs complex playing techniques such as pushing and rubbing the strings, the motion detection module 100 is provided on the guitar fingerboard. The motion data of the guitar fingerboard itself can be more accurately detected, so that the subsequent playing technique determination results are more accurate. Of course, the motion detection module 100 can also be provided on the guitar body. The motion detection module 100 may include various motion sensors. Preferably, the motion detection module 100 includes an inertial measurement unit (IMU), and specifically, a highly integrated IMU chip may be used, so as to accurately capture finger movements and playing techniques, especially complex techniques such as pushing and rubbing the strings, etc. Optionally, the motion detection module 100 includes an accelerometer and a gyroscope, which can also capture fingerboard movements.

[0029] After the motion detection module 100 acquires the motion data of the guitar fingerboard in real time, the motion data can be transmitted to the data processing module 200 in real time, and the data processing module 200 can identify the string-pushing action and / or string-rubbing action performed by the user in real time according to the received motion data. Specifically, the data processing module 200 may include a microcontroller unit (MCU), and the received data can be identified, analyzed and processed by the MCU. On the basis of supporting the string-pushing and string-rubbing function, based on the advanced sensing technology and accurate feedback of the motion detection module 100, and the optimization of the corresponding algorithm in the data processing module 200, the use of the virtual string fingerboard can also present more abundant advanced skills, such as simulating the shaking action of the electric guitar, etc., so that the user can experience the playing feeling that is almost indistinguishable from the real performance in the simulated environment.

[0030] When the user uses the vibrato technique, the guitar fingerboard itself and even the guitar body will produce a slight up and down shake, which can change the motion data collected by the motion detection module 100. The motion data collected by the motion detection module 100 is sent to the data processing module 200, and the data processing module 200 can analyze the motion data and identify the vibrato action. Specifically, the corresponding motion data threshold and / or motion data change threshold can be set in combination with the vibrato action of professional guitarists to compare the collected motion data with the corresponding motion data threshold, and / or the change amount of the collected motion data with the corresponding motion data change threshold, so as to determine whether the guitar fingerboard itself has shaken corresponding to the vibrato action, and then determine whether the user has performed the vibrato action.

[0031] When the user uses the bend technique, the guitar fingerboard itself and even the guitar body will have a large tilt angle change, and the tilt angle change can cause the motion data collected by the motion detection module 100 to change. The motion data collected by the motion detection module 100 is sent to the data processing module 200, and the data processing module 200 can analyze the motion data and identify the bend action. Specifically, the corresponding motion data threshold and / or motion data change threshold can be set in combination with the bend action of a professional guitarist, so as to compare the collected motion data with the corresponding motion data threshold, and / or compare the change amount of the collected motion data with the corresponding motion data change threshold, so as to determine whether the guitar fingerboard itself has a tilt corresponding to the bend action, and then determine whether the user has performed a bend action.

[0032] On the basis of the above technical solution, optional, such as Figure 2As shown, the smart guitar also includes: a pressure sensing module 300; the pressure sensing module 300 is used to obtain the pressure position data and pressure intensity data on the guitar fingerboard in real time, and transmit the pressure position data and the pressure intensity data to the data processing module 200; the data processing module 200 is specifically used to identify the string bending action and / or the string vibrato action according to the motion data, the pressure position data and the pressure intensity data. Specifically, combining the pressure position data and the pressure intensity data can make the recognition result of the string bending action or the string vibrato action more accurate, such as determining whether the user actually performs the string bending action or the string vibrato action, rather than simply shaking the guitar. When the user vibrato or bends the string, the finger's pressure position will change, and the pressure on different pressure positions may also change, so that the string bending action and / or the string vibrato action can be identified in combination with the motion data, the pressure position data and the pressure intensity data. Furthermore, the pressing position data and the pressing force data can correspond to the pitch, so that the combination of the motion data, the pressing position data and the pressing force data can also make the subsequent simulated sound closer to the pushing and rubbing of the strings of a real guitar.

[0033] Further optionally, the pressure sensing module 300 includes a pressure sensor and / or a contact sensor. Specifically, the corresponding sensors can be set to simulate the strings and frets of a traditional guitar, and more sensors can be additionally set between the simulated string positions and at the fret positions, so as to more accurately determine the pressing position data and the pressing force data. The pressure sensing module 300 can also be used to capture the user's string pressing action as described above, that is, the common pressure sensing module 300 is used to capture common fingering.

[0034] Further optional, such as Figure 3 As shown, the smart guitar further includes a string-plucking detection module 400; the string-plucking detection module 400 is disposed on the guitar body and is used to obtain string-plucking data in real time. Specifically, the string-plucking function part on the guitar body can use real strings, and the string-plucking detection module 400 can include a vibration sensor, and can obtain string-plucking data by detecting the vibration of the string. Alternatively, a virtual string can be used, and the string-plucking detection module 400 can include a pressure sensor or a contact sensor corresponding to the string, and can obtain string-plucking data by detecting the user's pressure.

[0035] Further optionally, the data processing module 200 is also used to: generate a performance digital signal in real time according to the motion data, the pressing position data, the pressing force data and the string-plucking data. Specifically, after the string-bending action and / or string-rubbing action are obtained according to the motion data, or after the string-bending action and / or string-rubbing action are obtained by combining the motion data, the pressing position data and the pressing force data, the corresponding string-bending sound signal and / or string-rubbing sound signal can be simulated and generated. In addition, the corresponding single-click sound signal or chord sound signal, etc. can also be generated according to the pressing position data, the pressing force data and the string-plucking data.

[0036] Further optional, such as Figure 4 As shown, the smart guitar also includes: a communication module 500; the data processing module 200 is also used to send the performance digital signal to the playback device through the communication module 500, so as to perform audio processing and playback through the playback device. Specifically, through the processing of the data processing module 200, various performance actions of the user can be converted into performance digital signals, and can be transmitted to the playback device such as a computer, a mobile phone, a stereo, etc. in real time through the communication module 500, which can be a wireless communication module such as Bluetooth or WiFi, or a wired communication module such as a data cable. After receiving the performance digital signal, the playback device can parse the performance digital signal and simulate the corresponding sound for playback.

[0037] The smart guitar based on the virtual string fingerboard provided by the embodiment of the present invention includes a motion detection module and a data processing module. The motion detection module can obtain the motion data of the guitar fingerboard in real time, and transmit the obtained motion data to the data processing module in real time, and then the data processing module can identify the bending and / or vibrato according to the received motion data. By adding a motion detection module to the smart guitar based on the virtual string fingerboard to detect the motion data, and improving the data processing module to identify the bending and / or vibrato according to the motion data, the smart guitar can more accurately capture the finger movements and posture information of the performer, thereby realizing the recognition and simulation of complex playing techniques such as the bending and vibrato functions of the smart guitar without strings on the fingerboard, improving the expressiveness and realism of the smart guitar, and making it closer to the playing experience of the traditional guitar. At the same time, the product does not require real strings, and the user does not need to operate the real strings, thereby avoiding the pain and fatigue of beginners when practicing the bending and vibrato techniques for a long time, making the smart guitar easier to use and reducing the difficulty of product maintenance.
