Description

Technical Field

[0001] The present invention relates to the technical field of music teaching, and in particular to an intelligent digital audio system for music teaching. Background Art

[0002] With the gradual improvement of educational standards across China, many schools have built professional music classrooms to provide music instruction. Furthermore, many music schools are steadily improving their educational and teaching standards, leading to rapid development of music instruction in recent years. Music instruction is the process of cultivating students' understanding, expression, and creativity in music through various methods and strategies. It involves not only imparting musical knowledge but also musical skills, emotional expression, and an understanding of musical culture. The goal of music instruction is to enable students to master the fundamental elements, techniques, and history of music while also cultivating their musical perception and creative thinking. While music instruction is more engaging than other subjects, it can be challenging to understand. Students must constantly comprehend the teacher's explanations and engage in classroom practice to fully appreciate the joy of music class. This requires effective collaboration between teachers and students. Current music instruction suffers from several drawbacks: 1. Students' learning positions are often adjusted based on their specific needs, resulting in poor visual and acoustic angles in many locations, hindering learning. 2. Due to the large size of music classrooms, teachers cannot adequately address every student's learning needs. Therefore, there is an urgent need for equipment suitable for music instruction.

[0003] Therefore, the present invention provides an intelligent digital audio system for music teaching. Summary of the Invention

[0059] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0060] Example 1:

[0061] This embodiment provides a smart digital audio system for music teaching. Figure 1 Shown, including:

[0062] A scene building module is used to determine the music style of this teaching according to the teaching task, and to construct a rendering scene of the teaching style of this teaching in combination with the spatial layout information of the teaching venue;

[0063] A screen coordination module is used to determine the learning needs of students based on the current teaching characteristics and display the screen on a screen display terminal related to the teaching style rendering scene;

[0065] The intelligent auxiliary module is used to obtain real-time site data of the teaching site, deduce the learning status of the students, and use the learning status to optimize the picture display and the sound playback in real time.

[0066] In this example, the teaching task represents the task that needs to be completed in this music teaching;

[0067] In this example, the spatial layout information includes the area of ​​the teaching venue, the boundary between the teaching area and the learning area, and the placement of various teaching equipment;

[0068] In this example, learning needs represent the conditions that students need to learn in order to master knowledge in music class;

[0069] In this instance, the current teaching characteristics represent the characteristics of the teaching knowledge presented by the teacher when teaching in the teaching venue;

[0070] In this example, the optimal playback mode refers to the playback mode determined according to the actual teaching situation;

[0071] In this example, the teaching style rendering scene represents the teaching style set for the teaching venue, and the scene of cooperating with the teacher in teaching during the subsequent class;

[0072] In this example, the learning state includes a normal learning state and an abnormal learning state. The normal learning state indicates that the current picture and sound meet the student's learning needs, and the abnormal learning state indicates that the current picture or sound does not meet the student's learning needs.

[0073] The working principle and beneficial effects of the above technical solution: In order to improve the teaching quality, guide students to learn music and assist teachers in teaching, first, the teaching style rendering of the teaching venue is built according to the teaching tasks, and then the students' learning needs are identified in real time during the teaching process, and then the corresponding picture is displayed in the teaching style rendering scene. At the same time, the best playback method is selected for sound playback based on the picture display and current teaching characteristics. In this way, teachers and students can be cooperated in teaching and learning, and the students' learning quality and the quality of the learning environment can be improved on the basis of ensuring the fun of music teaching. At the same time, in order to further avoid the picture and sound being out of sync and avoid the students' learning status being "offline", the sound and picture are optimized according to the real-time venue data, the quality of music teaching is improved, and new functions are added to the audio, which can be widely used in education and teaching in different scenarios and different grades.

[0074] Example 2:

[0075] On the basis of Example 1, the smart digital audio system for music teaching, such as Figure 2 As shown, the scene building module includes:

[0076] A task analysis unit is used to screen a plurality of teaching information included in the teaching task, and match a corresponding music melody to the corresponding teaching information according to the information attribute corresponding to each teaching information, and decompose the teaching task to obtain the task logical structure of this teaching;

[0077] A music matching unit is used to map each of the music melodies into the task logic structure to perform music reorganization, and to construct a music score file corresponding to the reorganized music in each preset music mode, obtain existing music with the highest similarity to each of the music score files and the corresponding existing music type in the big data, and deduce the music style of this teaching;

[0078] a scene planning unit, configured to obtain spatial layout information of the teaching venue, determine teaching conditions and learning conditions corresponding to each area of ​​the teaching venue, arrange teaching for each area according to the teaching conditions and the music style, and optimize the teaching arrangement corresponding to each area using the learning conditions corresponding to the scene area;

[0079] The style rendering unit is used to construct a virtual teaching venue according to the teaching arrangement and teaching optimization corresponding to each of the venue areas, simulate the teaching tasks in the virtual teaching venue, obtain the style presentation characteristics corresponding to each of the venue areas, and construct the teaching style rendering scene of the current teaching according to the style presentation characteristics corresponding to each of the venue areas.

[0080] In this example, the teaching information refers to the information about the current teaching needs contained in the teaching task;

[0081] In this example, the task logic structure represents the logic between the knowledge involved in this teaching;

[0082] In this example, the music score file represents a music score generated according to the music melody;

[0083] In this example, the teaching conditions represent the conditions that teachers need to provide when teaching in a certain area, and the learning conditions represent the conditions that students can achieve when learning in a certain area. For example, if the distance between scene area A and the sound system is 5 meters, the teaching condition is to amplify the lecture sound during teaching, and the learning condition is to pay attention to the teacher's lecture sound in real time.

[0084] In this example, teaching arrangement refers to the process of determining the minimum listening sound value corresponding to each venue area according to the music style, and then adjusting the placement of the speakers;

[0085] In this example, the preset music mode refers to a plurality of music modes that are set in advance and need to be learned in the teaching of this grade, such as: major mode, minor mode, Dorian mode, Phrygian mode, Lydian mode, mixed Lydian mode, Locrian mode, chromatic mode, pentatonic scale, whole tone scale, and blues scale;

[0086] In this example, the style presentation feature represents the content related to the music style presented in a venue area.

[0087] The working principle and beneficial effects of the above technical solution: In order to ensure the quality of teaching, the teaching environment must be arranged and rendered before teaching so that students can be immersed in the learning environment. First, the corresponding music melody is matched for this teaching according to the teaching task, and the task logic structure of this teaching is determined. The task logic structure is used to reorganize the music melody and then construct the corresponding score file of the reorganized music under different music modes. The music style of this teaching is determined in combination with the existing music. Then, the teaching conditions and learning conditions corresponding to each venue area are determined according to the spatial layout information of the teaching venue, and the mechanical teaching arrangement and layout optimization of the venue area are carried out. Finally, the style corresponding to each venue area is analyzed through virtual simulation, thereby completing the teaching style rendering of the teaching scene. In this way, not only the quality of this teaching work can be ensured, but teachers can also use the convenience of rendering scenes to better teach during the teaching process, thereby increasing the role and function of music and sound.

[0088] Example 3:

[0089] Based on Example 2, the process of deriving the music style of the current teaching by the intelligent digital audio system for music teaching includes:

[0090] Determining the music type of the music score file corresponding to the music score file according to the existing music type corresponding to each of the existing music;

[0091] When all the music scores are of the same type, the music style corresponding to the existing music type is identified as the music style of the current teaching;

[0092] On the contrary, the note data corresponding to each of the music score files are respectively identified to determine the corresponding music rhythm;

[0093] Determining the playback dynamic feature corresponding to each of the music score files according to the time value distribution corresponding to each of the music rhythms;

[0094] A teaching simulation is performed according to each of the dynamic playback characteristics and the teaching task, and the learning effect corresponding to each of the venue areas when using different music score files is obtained. The target music score file is selected according to the learning effect to determine the music style of this teaching.

[0095] In this example, the note data represents the data presented by the arrangement of notes in the music score file;

[0096] In this example, musical rhythm refers to the organization of notes and rests in music.

[0097] The working principle and beneficial effects of the above technical solution are as follows: by analyzing the similarity between the music score file and the existing music, the corresponding music style is deduced, and different operations are performed for the two situations where the music styles of all music score files are consistent or inconsistent, thereby determining the music style of this teaching and laying a teaching foundation for subsequent music teaching.

[0098] Example 4:

[0099] Based on Example 1, the smart digital audio system for music teaching, wherein the picture coordination module includes:

[0100] a feature recognition unit, configured to determine several teaching objectives of the current teaching according to the teaching task, obtain a current teaching scene in the teaching venue, accumulate teaching effects corresponding to the current teaching scenes at different times, and obtain a current teaching feature of the teaching venue;

[0101] a demand identification unit, configured to identify, in the teaching task, the teaching progress corresponding to the current teaching feature and the corresponding teaching objective at the current moment, match the current teaching feature with the teaching objective, and construct the learning demand corresponding to the student in achieving the teaching objective at the current moment;

[0102] A demand realization unit is used to locate several screen display terminals included in the teaching style rendering scene, allocate corresponding teaching display content to each screen display terminal according to the learning needs and the teaching tasks, and simultaneously obtain the teacher's teaching actions and the student's learning actions to build a real-time teaching process;

[0103] The synchronization corresponding unit is used to use the real-time teaching process to analyze the real-time teaching needs of the teacher and the real-time learning needs of the students, control each of the screen display terminals to perform synchronized primary display according to the real-time teaching needs, and control each of the screen display terminals to perform synchronized secondary display according to the real-time learning needs.

[0104] In this example, the current teaching scene refers to the images and sounds presented in the teaching venue at the current moment;

[0105] In this example, the synchronous primary display means that the screen corresponding to the teacher's real-time teaching needs is displayed first, and the synchronous secondary display means that the screen corresponding to the student's real-time learning needs is not displayed first.

[0106] The working principle and beneficial effects of the above technical solution: Since the teaching process is an interactive process, teachers and students have different needs during the teaching process. In order to respond to the needs of teachers and students in a timely manner and ensure the quality of teaching, the teaching tasks are first divided into several teaching objectives, and then the current teaching characteristics of the teaching venue are obtained by accumulating the current teaching scenes corresponding to different times. Furthermore, the students' learning needs are determined according to the current teaching progress and teaching objectives, and then the real-time teaching process is constructed according to the teaching display content of each screen display terminal and the teacher's teaching actions. Finally, the teacher's real-time teaching needs and the student's real-time learning needs are identified in the real-time teaching process, and the screen display terminal is controlled to display them. Since the teacher is the leader of the classroom, the teacher's needs are the main focus during the teaching process, and the screen display terminal is controlled to display the teacher's needs first to ensure classroom order.

[0107] Example 5:

[0108] Based on the fourth embodiment, the intelligent digital audio system for music teaching, wherein the synchronous response unit includes:

[0109] a teacher identification subunit, configured to bind a primary synchronization signal to the real-time teaching process according to the teaching action, and to identify the teaching action purpose corresponding to the teaching action when the primary signal value of the primary synchronization signal changes, thereby determining the real-time teaching demand issued by the teacher;

[0110] a demand determination subunit, which binds a secondary synchronization signal to a range outside the signal range of the primary synchronization signal, and when a secondary signal value of the secondary synchronization signal changes, locates the corresponding dynamic student in the teaching scene, determines whether the dynamic learning action corresponding to the dynamic student responds to the real-time teaching demand, and if so, constructs the real-time learning demand of the dynamic student according to the dynamic learning action;

[0111] The screen synchronization sub-unit is used to configure the primary response weight for the real-time teaching demand and the secondary response weight for the real-time learning demand. When the real-time teaching demand conflicts with the real-time learning demand, each of the screen display terminals is controlled to perform primary display. Conversely, each of the synchronous display terminals is controlled to perform synchronous primary display and synchronous secondary display respectively.

[0112] In this example, the primary synchronization signal represents a link that binds the real-time teaching process to the display screen, and the synchronous display terminal gives priority to displaying the screen corresponding to the primary synchronization signal; the secondary synchronization signal represents a link that binds the real-time teaching process to the display screen, and the synchronous display terminal does not give priority to displaying the screen corresponding to the primary synchronization signal;

[0113] In this example, the primary response weight is greater than the secondary response weight.

[0114] The working principle and beneficial effects of the above technical solution: In order to avoid the terminal screen being disordered or too jumpy, affecting the classroom order, first, the primary synchronization signal is bound to the real-time teaching process according to the teacher's teaching behavior, and the secondary synchronization signal is bound to the area outside the coverage of the signal. Then, by identifying the real-time teaching needs issued by the teacher and the real-time learning needs of the students, when the signal value of the corresponding signal changes, it means that the screen needs to be switched or operated, and the corresponding terminal is controlled to respond to the synchronization signal, and give priority to responding to the signal sent by the teacher, so as to provide students with the opportunity for independent learning while ensuring the progress of the class.

[0115] Example 6:

[0116] Based on Example 1, the intelligent digital audio system for music teaching, wherein the sound coordination module includes:

[0117] A collaborative alignment unit is configured to construct real-time teaching synchronization information of the teaching venue according to the screen display status in the teaching venue and the current teaching characteristics, obtain the teacher's real-time teaching voice and perform semantic recognition to obtain the real-time voice synchronization information of the current teaching;

[0118] a fusion playback unit, configured to obtain the real-time personnel distribution of the teaching venue and the distribution of fixed players in the teaching venue, determine the playback volume corresponding to each fixed player according to the real-time personnel distribution, and fuse the real-time teaching synchronization information and the real-time voice synchronization information to transmit to each fixed player for playback;

[0119] The emphasis highlighting unit is used to identify the teaching emphasis sound and the corresponding key teaching position corresponding to the current playback moment according to the real-time voice synchronization information, and control the fixed player corresponding to the key teaching position to enhance the playback of the teaching emphasis sound.

[0120] In this example, the real-time teaching synchronization information represents the sound produced in conjunction with the teaching screen during the teaching process, and the real-time voice synchronization information represents the sound made by the teacher when teaching.

[0121] The working principle and beneficial effects of the above technical solution: Since most of the teaching in music class relies on sound, the real-time teaching synchronization information and real-time voice synchronization information of this teaching are determined according to the picture display in the teaching venue and the teacher's real-time teaching voice, and the corresponding playback volume is matched for each fixed player in combination with the personnel distribution in the teaching venue and the distribution of fixed players in the teaching venue. Then, the real-time teaching synchronization information and the real-time voice synchronization information are integrated and played, and enhanced processing is performed on key positions to ensure that every student can be immersed in the music class and receive the influence of music.

[0122] Example 7:

[0123] Based on Example 1, the smart digital audio system for music teaching, wherein the smart auxiliary module comprises:

[0124] a real-time monitoring unit, configured to obtain real-time venue data of the teaching venue and real-time rendering data of the teaching style rendering scene, determine whether the real-time venue data is consistent with the real-time rendering data, and if so, determine that the student is in a normal learning state;

[0125] a defect identification unit, configured to determine that the student is in an abnormal learning state when the real-time venue data is inconsistent with the real-time rendering data, and determine a plurality of teaching defects of the teaching venue based on the data differences between the real-time venue data and the real-time rendering data;

[0126] An optimization execution unit is used to optimize the screen display and the sound playback in real time according to the defect type and defect value of the teaching defect.

[0127] The working principle and beneficial effects of the above technical solution: In order to ensure the quality of teaching and avoid the phenomenon of audio and video being out of sync that affects students' learning state, the real-time site data and implementation rendering data are used to determine whether the students are in a normal learning state. When the students are not in a learning state, the picture display and music playback are optimized and adjusted according to the defect type and defect value to ensure the smoothness of the teaching scene.

[0128] Example 8:

[0129] Based on Example 7, the smart digital audio system for music teaching further includes:

[0130] When the defect type is a sound type, performing sound optimization on the teaching scene according to the defect value;

[0131] When the defect type is a display type, the teaching scene is optimized according to the defect value;

[0132] When the defect type includes the sound type and the display type, the sound-display time difference of the teaching venue is determined according to the defect data value, and the sound-picture alignment optimization is performed on the teaching scene.

[0133] The working principle and beneficial effects of the above technical solution are: different optimization treatments are performed for different types of defects, ensuring classroom order and improving students' learning interest.

[0137] When the real-time site data contains the timbre feature, the teaching audio of the teaching instrument is enhanced.

[0138] The working principle and beneficial effects of the above technical solution: Musical instruments play an especially important role in music classes, so the sound of the teaching instruments is enhanced during the teaching process to ensure that every student can hear the sound of the instrument clearly.
