Description

Technical field:

[0001] The present invention relates to the technical field of intelligent guitars, and in particular to an intelligent guitar pick control system and method. Background technology:

[0002] At present, smart guitars have become a popular choice for music lovers and guitar learners. By integrating sensors and processors, smart guitars can realize functions such as music score display and playing rhythm control, allowing users to learn and play guitar more conveniently. However, most existing smart guitar picks use a single trigger logic (such as switch-type pickup), and their modes are rigid. They cannot distinguish between singing, single notes, improvisation and other scene requirements, lack targeted interactive logic, and are not convenient to use. Summary of the invention:

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an intelligent guitar pick control system and method. Through a three-mode architecture consisting of a singing mode, a single-note follow-up mode, and an AI improvisation mode, combined with a lever velocity sensing and chord key combination triggering mechanism, this system achieves force-controlled rhythm generation. The system supports score follow-up determination, AI collaborative creation, and Wi-Fi downloading of multiple-source songs (pre-set or AI-generated), addressing the problem of traditional picks lacking intelligent interactive mode switching and dynamic response.

[0004] To achieve the above objectives, the present invention provides a technical solution that is an intelligent guitar pick control system, comprising:

[0005] The mode switching module provides three working modes: singing and playing mode, single-note follow-up mode, and AI improvisation mode;

[0006] The lever assembly includes lever A and lever B, which are used to detect downward or upward movement and pushing speed;

[0007] The chord key module detects the chord pressing status of the user's left hand;

[0008] Control logic module for:

[0009] The function is only triggered when the paddle movement and the chord grid key combination operation are detected. Triggering the chord grid key alone will produce a string-fingered effect sound.

[0010] Dynamically adjust the output rhythm strength according to the speed of the lever push, and the speed and strength are positively correlated;

[0011] By default, lever A triggers flat chords, and lever B triggers strummed chords.

[0012] A further improvement to the above scheme is that the singing and playing mode includes:

[0013] Sing-and-play: directly enter the singing part without MIDI score, and a single lever action triggers a chord rhythm pattern;

[0014] Sing-along the whole song: When playing a song with MIDI music, trigger the lever in the prelude, interlude or ending section to play a measure of the MIDI music, and trigger a single chord rhythm pattern in the singing section.

[0015] A further improvement to the above solution is that, in the single-note follow-up mode, the lever action triggers the device to play a measure of MIDI music.

[0016] A further improvement to the above solution is that in the AI ​​improvisation mode:

[0017] A single lever action triggers the playback of an MP3 or WAV audio clip;

[0018] When switching songs within the same mood playlist, a stop signal must be received to terminate the current playback;

[0019] Supports configuration of music style parameters through APP, and configuration data is saved after power failure;

[0020] A further improvement to the above solution is that it also includes a music score following module. When the chord block is displayed in the screen judgment area, it synchronously detects the left-hand chord pressing and the right-hand plucking action or the right-hand triggering single-tone module action. After verifying the match, it plays the pre-stored MP3 or WAV clip and the corresponding single tone.

[0021] In another aspect, the present invention provides a song generation method, applied to the system according to claim 1, comprising the following steps:

[0022] In AI creation mode, the app guides users to input chords, styles, and lyrics;

[0023] Send chord suggestion information to the smart guitar to guide the user to press the best chord key;

[0024] Upload the user's transposition or speed change operations on the smart guitar to the cloud server in real time as AI-generated parameters;

[0025] After the song is generated, it is sent to the smart guitar in the form of sliced ​​MP3 or WAV+JSON files.

[0026] A further improvement to the above solution is that guiding the user input through the APP specifically includes:

[0027] Provide chord input module, style selector and lyrics editing box on the APP interface;

[0028] Dynamically generates a list of chord progression suggestions based on the user's selected musical style.

[0029] A further improvement to the above solution is that sending the chord suggestion information to the smart guitar specifically includes:

[0030] Send chord pressing coordinate data to the smart guitar via Bluetooth or WIFI;

[0031] Drive the LED indicator array on the smart guitar neck to illuminate the optimal pressing position for the corresponding chord.

[0032] A further improvement to the above solution is that the real-time uploading of the user's transposition or speed change operation on the smart guitar includes:

[0033] Monitor the change signal of the physical transposition touch button of the smart guitar;

[0034] Capture rhythmic speed adjustment gestures in the paddle area;

[0035] Synchronize transposition and tempo parameters to the cloud server in real time.

[0036] A further improvement to the above solution is that the structure of the MP3 or WAV+JSON file includes:

[0037] MP3 or WAV audio slices: audio files stored in segments;

[0038] JSON data: includes chord trigger sequence, slice start and end timestamps, tempo, tonality, and chord properties.

[0039] The beneficial effects of the present invention are as follows: the present invention includes a mode switching module, which provides three working modes: singing mode, single-note follow-up mode, and AI improvisation mode; a lever assembly, including lever A and lever B, for detecting downward or upward plucking movements and pushing speed; a chord key module, which detects the chord pressing state of the user's left hand; a control logic module, which is used to: trigger the function only when a combination of lever movement and chord grid key operation is detected, and triggering the chord grid key alone will produce a rubbing effect sound; dynamically adjust the output rhythm strength according to the lever pushing speed, and the speed is positively correlated with the strength; the default configuration is that lever A triggers broken chords, and lever B triggers strummed chords;

[0040] The present invention can switch between singing and playing, single-note, and AI improvisation modes. The singing and playing mode is adapted to chord accompaniment scenarios, the single-note singing and playing focuses on melody learning, and the AI ​​improvisation mode meets creative needs, covers users' needs in different scenarios, and is highly practical. At the same time, an anti-false triggering mechanism is provided, which requires the lever action and chord pressing combination to trigger, to avoid accidental touching of the lever during performance and causing noise, to ensure the normal progress of the performance, and at the same time can dynamically adjust the output force according to the pushing speed of the push rod, to effectively improve the expressiveness of the performance, and the lever can realize different functions, which can reduce the user's learning cost and improve the operation consciousness.
