Description

Technical Field

[0001] This invention belongs to the field of intelligent interactive technology for electronic musical instruments, specifically relating to a segmented music performance triggering method and system, which can be widely applied to portable pocket electronic musical instruments, smart guitars, handheld music synthesizers, and other low-threshold music performance devices for users with no prior experience. Background Technology

[0002] With the increasing demand for popularizing music among the general public, the market size of portable electronic musical instruments with low barriers to entry for users with no prior experience has continued to grow in recent years. These products simplify the complex fingering logic of traditional string and keyboard instruments, allowing users to quickly complete performances without systematically learning music theory, thus significantly lowering the barrier to entry for music creation.

[0003] Currently, low-barrier electronic musical instruments on the market mainly adopt an interactive architecture of "button selection + pick trigger". Existing related technologies have a certain functional foundation, but there are still many shortcomings: 1. Hardware architecture level: For example, the intelligent guitar pick control system disclosed in Chinese patent CN120766639A uses two independent levers to correspond to the trigger logic of arpeggio and strumming respectively. Although it can achieve the switching of different playing effects, the hardware design of dual levers not only increases the material cost by more than 20%, but also requires a larger layout space, which cannot adapt to the structural design requirements of miniature portable electronic musical instruments with a size of only a pocket.

[0004] 2. Interaction Logic Level: For example, the electronic musical instrument mode control method disclosed in Chinese Patent No. CN120748346A supports switching between singing / solo modes, but it adopts the logic of outputting complete audio by triggering a single pick. The performance effect is fixed. Users cannot achieve rich effects such as segmented performance and rapid arpeggio triggering by simply operating the pick. Under the premise that the operation threshold remains unchanged, the performance richness is only about 40% of that of professional instruments, which is difficult to meet the advanced creative needs of users.

[0005] 3. Experience optimization: Most existing electronic musical instruments only support local storage for user-defined configurations. When users switch devices, they need to reset all parameters. When there are more than 20 custom chord / arpeggio parameters, the average time for repeated configuration across multiple devices exceeds 10 minutes. The lack of cross-device synchronization capability results in a poor user experience.

[0006] In summary, existing low-barrier electronic musical instrument technologies cannot simultaneously meet the demands of low hardware costs, low operating barriers, and high performance richness. They are ill-suited for the mass production and deployment of pocket-sized portable electronic musical instruments and the advanced usage needs of users. A new performance triggering technology solution is urgently needed to address these shortcomings. Summary of the Invention

[0007] The background technology addresses three distinct technical shortcomings: First, the hardware cost of electronic musical instruments with a dual-lever architecture is more than 20% higher, and the space required for trigger component layout is large, making it unsuitable for the miniaturization design requirements of pocket-sized portable devices. Second, electronic musical instruments with a single trigger component use a logic of outputting complete audio with a single trigger, resulting in only 40% of the performance richness of professional instruments, making it impossible to balance operational difficulty with performance richness. Third, custom configuration only supports local storage, and repeated configuration across multiple devices takes an average of more than 10 minutes, leading to a poor user experience.

[0008] The purpose of this invention is to provide a segmented music performance triggering method and system that reduces hardware costs, adapts to the miniaturization of portable devices, and balances low operating threshold with high performance richness. It also supports cross-device configuration synchronization and is fully adapted to the mass production and deployment of low-threshold portable electronic musical instruments and the advanced usage needs of users.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a segmented music performance triggering method, applied to an electronic performance device including a touch selection unit and a bidirectional pick triggering unit. Specifically, it includes the following steps: First, receiving a performance mode configuration instruction, determining the currently running performance mode, and configuring a corresponding audio resource mapping relationship for the touch selection unit: In the first performance mode, each trigger position of the touch selection unit corresponds to a preset chord audio segment, and each chord audio segment is pre-divided into a first segment and a second segment with sequentially continuous time; in the second performance mode, each trigger position of the touch selection unit corresponds to a preset single-note resource. Then, receiving the trigger signal from the touch selection unit, the target audio resource selected by the user is determined. Finally, the input operation of the bidirectional pick trigger unit is detected: in response to the first direction trigger operation of the bidirectional pick trigger unit, if the current performance mode is the first playing mode, the first segment corresponding to the target audio resource is played; if the current performance mode is the second playing mode, the single note corresponding to the target audio resource is played; in response to the continuous first direction trigger operation received by the bidirectional pick trigger unit after the first segment is played, the second segment corresponding to the target audio resource is played, and the first segment and the second segment are spliced ​​together to form a complete chordal rhythm audio segment; in response to the second direction trigger operation of the bidirectional pick trigger unit, the preset arpeggio audio resource corresponding to the target audio resource is played.

[0010] Furthermore, in the above steps, the first direction triggering operation and the second direction triggering operation are determined by the Hall sensor built into the bidirectional paddle triggering unit to detect the direction of the paddle displacement. The interval threshold between two consecutive first direction triggering operations is 80ms-300ms. If the interval threshold is exceeded, it is determined to be a new first segmented triggering operation.

[0011] Furthermore, in the first performance mode, the duration of the first and second segments of the chord audio clip is split by default according to the first two beats and the last two beats of 4 / 4 time, and the timbre and rhythm pattern of the two segments remain consistent.

[0012] Furthermore, in the above steps, the performance mode configuration command is triggered by the physical mode button on the electronic performance device, and the status feedback is provided by the color change of the fingerboard side light when switching modes: blue light corresponds to the first performance mode, and yellow light corresponds to the second performance mode.

[0013] Furthermore, the number of chord audio segments, the duration of each segment, and the rhythm pattern can be customized by the user in the associated mobile app, and the configuration is synchronously stored on the local electronic performance device after completion.

[0014] Furthermore, in the above steps, when a long press operation of the bidirectional pick trigger unit is detected, a drum machine rhythm embellishment effect is triggered, and the style of the embellishment effect matches the style of the currently played chord rhythm.

[0015] Furthermore, the arpeggio audio resource corresponding to the second direction trigger operation allows the user to select any one of ascending arpeggio, descending arpeggio, or broken chord arpeggio, and the speed of the arpeggio is synchronized with the speed of the currently played chord rhythm.

[0016] Furthermore, the plucking speed of the bidirectional plectrum trigger unit is positively correlated with the playing force of the output audio; the faster the plucking speed, the louder the volume and the brighter the timbre of the output audio.

[0017] Furthermore, in the above steps, when the user selects the target audio resource, the indicator light at the corresponding touch trigger position flashes to indicate this, while the fingerboard side light breathes and flashes at the beat frequency of the current rhythm.

[0018] Furthermore, user-defined chord segment configurations can be synchronized via the cloud to multiple electronic performance devices bound to the same account.

[0019] Furthermore, user-defined arpeggio configurations can be synchronized via the cloud to multiple electronic performance devices bound to the same account.

[0020] This invention also provides a segmented music performance triggering system integrated into a portable electronic performance device, specifically including a mode configuration module, a touch selection module, a two-way pick trigger module, a segmented performance control module, and an audio output module: The mode configuration module is used to receive performance mode configuration instructions, switch the system's performance modes, and configure the audio resource mapping relationship for the touch selection unit in the corresponding mode: in the first performance mode, it maps chord audio segments pre-split into two sequentially continuous segments; in the second performance mode, it maps single-note resources; the touch selection module is a button array containing at least 7 groups of 14 touch trigger positions, used to receive user selection operations and output target audio resources. The selection signal of the source; the bidirectional pick trigger module is a single trigger component that can recognize two opposite directions of plucking operations, up and down, and is used to receive the user's plucking operation and output the corresponding direction trigger signal; the segmented performance control module is used to respond to the first direction trigger signal of the bidirectional pick trigger module to play the segmented audio of the selected target audio resource in sequence, and the audio segments corresponding to two consecutive first direction trigger signals are spliced ​​into a complete chordal rhythm audio; in response to the second direction trigger signal of the bidirectional pick trigger module, the arpeggio audio corresponding to the selected target audio resource is played; the audio output module is used to convert the audio signal output by the segmented performance control module into sound output.

[0021] Furthermore, the bidirectional paddle trigger module has a built-in Hall sensor and displacement detection circuit, which can identify paddle operations in both upward and downward directions, and can also detect paddle speed and paddle duration parameters.

[0022] Furthermore, the system also includes a sheet music linkage module, which is used to receive sheet music data sent by the associated mobile APP. During the performance, the fingerboard side light provides real-time prompts for the position of the touch trigger to be triggered, and the user can complete the performance of the complete piece by following the prompts.

[0023] Furthermore, the audio output module is integrated inside the electronic performance device and is a high-fidelity speaker with a rated power of 5W, supporting wired audio output via Type-C interface and Bluetooth wireless audio output.

[0024] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. Hardware cost and miniaturization optimization: The traditional dual lever layout is replaced by a single bidirectional lever, which reduces the material and structural cost of one trigger component, resulting in a 20% reduction in overall hardware cost and a 15% reduction in the layout space required for the trigger component, making it fully compatible with the miniaturization design requirements of pocket-sized portable electronic musical instruments.

[0025] 2. Improved performance interaction efficiency: Users with no prior experience do not need to master music theory or complex fingering techniques. They can complete various performance effects such as full chords, arpeggios, and drum machine embellishments simply by using two directions of simple pick operation. The instrument learning cycle is shortened by 80%, and the richness of performance is increased by 40% under the same operation complexity. The continuous trigger interval threshold setting of 80ms-300ms ensures the response efficiency during fast performance and avoids accidental triggering. The accidental touch rate during performance is reduced by 75%, and the smoothness of performance is improved by 50%.

[0026] 3. Customization and cross-device experience optimization: Supports custom configuration of chord segmentation parameters and arpeggio types, increasing the range of adaptable playing styles by 60%; the cloud synchronization function can synchronize user configurations to multiple devices with one click, reducing the time cost of repeated configuration on multiple devices by 90%; with the music score linkage light prompt function, even users with no experience can play the complete piece by following the light, increasing the completion rate of beginner pieces by 70%.

Detailed Implementation

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0029] The segmented music performance triggering method and system described in this embodiment are applied to a pocket-sized portable electronic performance device 201. The device is equipped with an ARM Cortex-M4 main control chip, has 2MB of built-in Flash storage, and supports Bluetooth 5.2 connection to a mobile APP 501. It achieves a low-threshold and high-rich performance effect through a single and two-way pick triggering architecture. The following is a detailed description of this solution with reference to the accompanying drawings: refer to Figure 2 The method flow first executes the performance mode configuration step S101: the user presses the physical mode button 204 on the electronic performance device 201 to trigger the mode configuration command. The mode configuration module 101 configures the corresponding audio resource mapping relationship for the touch selection unit 202: in the first performance mode state 401, each trigger position of the touch selection unit 202 corresponds to a preset chord audio segment, and each chord audio segment is pre-divided into a first segment and a second segment with sequential time; in the second performance mode state 403, each trigger position corresponds to a preset single note resource. This rule allows the same set of touch buttons to simultaneously adapt to both chord accompaniment and melody solo scenarios without the need for additional hardware, reducing the overall hardware cost by 20%. In one embodiment of the present invention, the factory default mapping rule is C major, with the 7 touch positions corresponding to 7 diatonic chords from top to bottom: C, Dm, Em, F, G, Am, and Bdim. In another embodiment of the present invention, the user can customize the chord type and scale key corresponding to each touch position in the associated mobile APP 501. In a third embodiment of the present invention, the music score linkage module 106 can dynamically adjust the mapping relationship according to the currently playing music score, automatically adapting to the special chords / scales required by the music score. (Status feedback reference during mode switching) Figure 4 In the first playing mode 401, the fingerboard side light 205 is blue (not the yellow fingerboard side light indicator 402). In the second playing mode 403, the fingerboard side light 205 is yellow (the yellow fingerboard side light indicator 404). Users can intuitively identify the current mode without having to memorize the operation status.

[0030] Then, the target audio resource selection step S102 is executed: the main control chip receives the trigger signal from the touch selection unit 202, determines the target audio resource selected by the user, and the indicator light corresponding to the selected touch position flashes to indicate this. At the same time, the fingerboard side light 205 breathes and flashes at the beat frequency of the current rhythm. This dual indication can reduce the probability of accidental touch by the user and improve the selection accuracy by 60%. In one embodiment of the present invention, the user can select the target audio resource by short-pressing the touch position and retain the selected state after releasing it until switching to other buttons. In another embodiment of the present invention, the user can bring up the local parameter editing interface by long-pressing the touch position and directly modify the audio resource corresponding to the button on the device. In a third embodiment of the present invention, pressing multiple touch positions at the same time can trigger a custom chord combination to meet the personalized performance needs of advanced users.

[0031] Finally, perform the bidirectional paddle input detection step S103: (Refer to...) Figure 3The hardware structure includes a bidirectional pick trigger unit 203 with a built-in Hall sensor 2031 and displacement detection circuit 2032. It determines the first / second direction trigger operation by detecting the displacement direction of the built-in magnet. In this embodiment, the first direction is downward plucking and the second direction is upward plucking. Users can adjust the direction mapping rules in the system settings according to their operating habits. First, the first direction trigger response sub-step S1031 is executed: In response to the first direction trigger operation of the bidirectional pick trigger unit 203, if the current state is the first performance mode 401, the first segment corresponding to the target audio resource is played; if the current state is the second performance mode 403, the single note corresponding to the target audio resource is played. Then, the continuous first direction trigger response sub-step S1032 is executed: If a continuous first direction trigger operation is received within an 80ms-300ms interval after the first segment is played, the second segment corresponding to the target audio resource is played. The first and second segments are combined to form a complete chord rhythm splicing result 305. Users only need two simple plucking movements in the same direction to complete the standard 4 / 4 time signature chord rhythm performance, reducing the learning threshold by 80%. In one embodiment of the present invention, the default interval threshold is 80ms-300ms, which is suitable for the operation speed of most ordinary users; in another embodiment of the present invention, the interval threshold is adjusted to 150ms-350ms in novice mode, which is suitable for users who are not proficient in operation to avoid missed triggers; in a third embodiment of the present invention, the interval threshold is adjusted to 50ms-250ms in professional mode, which is suitable for fast playing scenarios. The chord segmentation rules can be flexibly configured: by default, it is split according to 4 / 4 time, with the first segment occupying the first 2 beats and the second segment occupying the last 2 beats; it can also be set to split according to 3 / 4 time, with the first segment occupying 1 beat and the second segment occupying 2 beats, which is suitable for waltz and other three-beat rhythms; users can also customize the number of segments, the duration of each segment, and the rhythm pattern in the mobile APP 501, and after configuration, it is synchronously stored to the local electronic performance device 201. Finally, the second direction trigger response sub-step S1033 is executed: in response to the second direction trigger signal 306 of the bidirectional pick trigger unit 203, the arpeggio audio output 307 corresponding to the target audio resource is played. In one embodiment of the invention, the default arpeggio type is ascending arpeggio, suitable for the performance needs of most popular songs; in another embodiment, the user can choose to set it to either descending arpeggio or broken chord arpeggio, with the arpeggio speed automatically synchronized with the current chord rhythm speed; in a third embodiment, a long press of the bidirectional pick trigger unit 203 can output a long press trigger signal 308, triggering the drum machine embellishment audio output 309, with the embellishment style automatically matching the current chord rhythm style. Furthermore, the plucking speed of the bidirectional pick trigger unit 203 is positively correlated with the output audio performance intensity; the faster the plucking speed, the louder the output volume and the higher the timbre brightness, enabling dynamic expression of performance emotion. (Reference) Figure 5User-defined chord segmentation configurations and arpeggio type configurations can be synchronized to multiple electronic performance devices bound to the same mobile APP account via cloud synchronization server 502, such as the first electronic performance device 503 bound to the account and the second electronic performance device 504 bound to the account, reducing the time for repeated configuration of multiple devices by 90%.

[0032] refer to Figure 1 The system architecture of the segmented music performance triggering system described in this embodiment includes the following modules: A mode configuration module 101 is deployed in the main control chip, used to receive performance mode configuration instructions, switch system performance modes, and configure the audio resource mapping relationship in the corresponding mode for the touch selection module 102. The touch selection module 102 corresponds to the touch selection unit 202 in the hardware layer, which is a button array containing 7 groups of 14 capacitive touch trigger positions, used to receive user selection operations and output the selection signal of the target audio resource. In one embodiment of the present invention, the touch selection module 102 uses a capacitive touch array, which has high recognition sensitivity; in another embodiment of the present invention, a pressure-sensitive button array is used, which can adjust the output audio gain according to the pressing pressure; in a third embodiment of the present invention, a membrane button array is used, which has lower hardware cost and is suitable for entry-level products. The bidirectional paddle triggering module 103 corresponds to the bidirectional paddle triggering unit 203 in the hardware layer, which is a single triggering component that can recognize two opposite paddle operations, and has a built-in Hall sensor 2031 and displacement detection circuit 2032, which can simultaneously detect paddle speed and paddle duration parameters. The segmented performance control module 104 is deployed in the DSP processing unit of the main control chip. It responds to the first-direction trigger signal of the bidirectional pick trigger module 103, sequentially playing the segmented audio of the selected target audio resource. The audio segments corresponding to two consecutive first-direction trigger signals are spliced ​​together to form a complete chordal rhythm audio. It responds to the second-direction trigger signal to play the corresponding arpeggio audio. The audio output module 105 corresponds to the 5W high-fidelity speaker with a rated power integrated into the bottom of the electronic performance device 201, supporting wired audio output via Type-C interface 207 and Bluetooth wireless audio output. The score linkage module 106 is deployed in the main control chip, referencing... Figure 6 The interaction logic is used to receive sheet music data sent by the sheet music sending module 601 of the associated mobile APP 501. During the performance, the fingerboard side light trigger prompt 602 is output to provide real-time prompts on the position of the touch trigger position to be triggered. After the user operation detection module 603 recognizes the user's operation according to the prompt, the audio playback module 604 outputs the corresponding audio. Users with no experience can complete the performance of the complete piece by following the prompts, and the completion rate of beginner pieces is increased by 70%.

[0033] The scope of protection of this invention is not limited to the above embodiments. Several modifications and improvements can be made without departing from the core concept of this invention, and all of them fall within the equivalent protection scope of this invention. For example, the bidirectional pick trigger unit 203 can be replaced by an input component that can recognize bidirectional actions, such as a joystick, scroll wheel, or touch bar, and can still realize segmented triggering and arpeggio triggering functions. The number of chord audio segments can be expanded to 3 or 4 segments, corresponding to three or four consecutive pick triggers in the same direction spliced ​​into a complete rhythm, adapting to more complex rhythm patterns. In addition to being applied to portable pocket electronic musical instruments, this technical solution can also be applied to other types of electronic musical instruments such as smart guitars, electronic drums, electronic keyboards, and handheld synthesizers to achieve the same low-threshold playing effect. The triggering dimension of the bidirectional pick can be expanded to include pressing pressure and pressing duration, corresponding to more playing effects. The above modifications do not depart from the core technical concept of this invention and fall within the protection scope of this invention.
