Abstract
Description
Technical Field
[0001] This invention primarily relates to the field of trombone instruments, while integrating electronic and internet technologies. Traditional trombone playing involves a combination of blowing techniques and bowing operations, precisely controlling lip vibration, breath, and bowing position to achieve pitch variations. Building upon this, this invention simplifies playing through electronic sensing technology and a button control system, and introduces network connectivity to enable collaborative playing across multiple devices, thus realizing intelligent and socialized music creation. Background Technology
[0002] Traditional musical instruments produce sound through their own design, structure, materials, and other physical properties. Players use different operating methods to produce sounds of different frequencies. The traditional trombone, as a typical brass instrument, mainly consists of a mouthpiece, tuning tube, bow tube, and bell.
[0003] The trombone's intonation relies entirely on manual calibration of the pull tube position and precise coordination of the lip muscles, making it widely recognized as the most difficult brass instrument to control. The player alters the effective length of the tube by pushing and pulling, creating a system of seven characteristic positions, each corresponding to a fundamental pitch. Through lip vibration and breath control, more than ten overtones can be generated, achieving the expression of pitch and timbre. Breath control requires precise adjustment of airflow, pressure, and velocity to match pitch, volume, and timbre requirements, especially maintaining stable air pressure during the movement of the trombone to ensure a consistent sound. Subtle changes in embouchure tightness directly affect the brightness and pitch of the tone; too tight an embouchure results in a sharp tone and high intonation, while too loose an embouchure produces a dull tone and low intonation.
[0004] This invention provides a network-connected trombone instrument that produces sound independently of the traditional trombone's shape, material, and structure, simulating its acoustic characteristics through electronic technology. The device employs a combined control technology of a tube pressure sensing unit and a button unit to establish a digital pitch model. The player only needs to operate the tube and buttons to control the pitch, completely eliminating reliance on lip vibration and breath control. Simultaneously, an air pressure sensor maps the blowing pressure to volume and note duration, replicating the traditional trombone playing experience. This network-connected trombone instrument supports three working modes: individual manual playing, individual control playing, and collaborative playing. Collaborative playing enables multiple trombones to network and coordinate via a cloud platform, supporting differentiated parameter configurations to complete multi-part concertos and ultimately forming a complete networked concerto system to meet diverse musical composition and performance needs. Summary of the Invention
[0005] This design presents a network-connected trombone instrument that retains a similar traditional appearance while combining traditional charm with innovative functions. Modern electronic technology breaks through the limitations of traditional instruments' physical sound production and demonstrates advantages in reducing the skill requirements and learning difficulty of playing, thus improving the convenience and intelligence of playing the instrument. This trombone instrument includes a control module, a networking module, and a playing module, and can be used as a standalone playing terminal or to build an IoT-based intelligent band system. It is achieved through the following technical solution: A network-connected trombone instrument includes a control module, a networking module, and a playing module. The control module is used for system control and coordination, supporting individual manual playing, individual controlled playing, and collaborative playing modes. The networking module establishes a communication connection between the trombone instrument and the user terminal, and indirectly connects the user terminal device to a cloud platform, enabling the download of sheet music resources, acquisition of timbre data, uploading of playing information, and the construction of a personal playing database on the cloud platform. The playing module collects playing information through sensors and synthesizes audio for playback.
[0006] The control module is responsible for the control and coordination of the entire system, including interacting with the network module to exchange control commands and controlling the playing module to enable individual manual and automatic playing functions. The automatic playing function includes individual controlled playing and collaborative playing.
[0007] The networking module includes a communication unit and a human-computer interaction unit. The communication unit uses one or more of the following communication technologies: 4G, 5G, WIFI, and Bluetooth, to establish a communication connection with user devices (mobile phones, tablets). The human-computer interaction unit provides an interface for interaction between the user and the trombone instrument. Users interact via a mobile phone or tablet app, such as a QR code affixed to the surface of the trombone instrument, containing a unique ID code for easy account login. The human-computer interaction unit enables functions such as identity verification, sheet music acquisition, synchronization of playing parameters, and uploading of playing information through the user device. The human-computer interaction unit receives playing parameter information or repertoire information set by the user, including but not limited to timbre and rhythm, and transmits this information to the control module. The control module adjusts the audio synthesis of the playing module based on the received playing parameter information. The term "user" refers to a general user who communicates with the network module via an app on their mobile phone or tablet, including sending playing parameter information or repertoire information. The term "control user" refers to an advanced user who also uses an app on their mobile phone or tablet to control the networked concerto of trombone instruments. It is used for concerto control of multiple trombone instruments. It can control multiple trombone instruments, send playing parameter information or repertoire information, and issue control commands such as start concerto, pause, end, and concerto content to control the collaborative work of multiple trombone instruments.
[0008] The playing module includes a sound source unit, a breath inlet unit, a tube pressure sensing unit, a button unit, a playing information acquisition and synthesis unit, a sound production unit, and an operation control unit. It primarily collects playing information from the user through sensors, then synthesizes audio in real time based on this information and a timbre library, driving the sound production unit to play the audio.
[0009] The sound source unit of the playing module is a library of timbres for storing traditional trombone instruments, with a built-in storage medium (such as an SD card) for storing and managing timbre data downloaded from the user's device.
[0010] The breath port unit of the playing module has a built-in air pressure sensor that can sense the pressure of the breath blown by the player in real time and convert these physical quantities into electrical signals. These signals are then transmitted to the playing information acquisition and synthesis unit for processing, so as to accurately control the volume and duration of the notes played. In other words, the air pressure sensor collects the loudness (amplitude) and duration of the notes.
[0011] The playing module's tube pressure sensing unit incorporates a pressure sensor that detects pressure changes at four preset positions on the tube, corresponding to four reference pitches: the international standard pitches C2 (65.41Hz), D2 (73.42Hz), E2 (82.41Hz), and F2 (87.31Hz). This reference pitch design is based on the trombone's standard range (E1-Bb3) and covers the most commonly used mid-low range of the trombone through button combinations.
[0012] The key unit of the playing module includes a fifth key, a semitone key, two octave keys, and a transposition key. The fifth key raises the current reference pitch by a perfect fifth. The semitone key raises the current reference pitch by a semitone. The two octave keys are an octave sharp and an octave flat key. The transposition key is used to switch the reference pitch to other keys; the default is C major.
[0013] The transposition key must be used in combination with the octave key. In this case, the octave key acts as a transposition switch. Pressing the octave up key triggers a key shift, and pressing the octave down key triggers a key shift. For example, pressing the transposition key and the octave up key shifts the key to C#, with the reference pitch changing from C2, D2, E2, F2 to C#2, D#2, F2, F#2. Pressing the transposition key and the octave down key shifts the key to B, with the reference pitch changing from C2, D2, E2, F2 to B1, C#2, D#2, E2.
[0014] In any position of the pipe, the player can adjust the pitch using a combination of fifth, semitone, and octave keys, as shown below, taking the key of C as an example: (1) Fifth key: Raise the current reference pitch by a perfect fifth, such as C2→G2, D2→A2, E2→B2, F2→C3.
[0015] (2) Semitone key: Raises the current reference pitch by a semitone, such as C2→C#2, D2→D#2, E2→F2, F2→F#2.
[0016] (3) Octave Raise Key: Raise the current pitch by one octave, such as C2→C3, D2→D3, E2→E3, F2→F3.
[0017] (4) Lower octave key: Lower the current pitch by one octave, such as C2→C1, D2→D1, E2→E1, F2→F1.
[0018] The functions of each button can be used in combination. For example, pressing the fifth key and the semitone key simultaneously will achieve a pitch change of a perfect fifth plus a semitone, such as C2→G#2. The system achieves precise pitch control through the synergistic effect of the tube position and button combinations.
[0019] The playing information acquisition and synthesis unit simultaneously collects three types of playing data: the breath port unit, the pipe pressure sensing unit, and the button unit. The breath port unit acquires the air pressure parameters of the notes: the note amplitude represented by the amount of air and the note duration represented by the duration of airflow. The pipe pressure sensing unit acquires the position of the corresponding C2 / D2 / E2 / F2 reference pitch. The button unit acquires the button combinations consisting of transposition keys, fifth keys, semitone keys, and octave keys. Based on the pipe position and button combinations, the playing information acquisition and synthesis unit determines the note number of the target pitch, retrieves the corresponding timbre data from the sound source unit, and synthesizes an audio signal in real time by combining the air pressure parameters, driving the sound output unit to output the sound effect. Simultaneously, the system combines the target pitch note number and the corresponding note air pressure parameters from the playing data into playing information, uploads it to the cloud in chronological order, and constructs a user playing database to measure playing accuracy and evaluate playing level.
[0020] The sound unit further supports one or more of the following playback methods: speaker, headphones, Bluetooth speaker, for playing synthesized audio data.
[0021] The trombone instrument described herein has an appearance design similar to that of a traditional trombone, in order to retain the visual characteristics of a traditional trombone instrument. To maintain consistency with the characteristics of a traditional trombone, this invention only supports a single-note sound production mode.
[0022] The operation control unit includes a power switch, volume adjuster, mode switcher, chord selection button, and accompaniment control button; the mode switcher refers to switching between three modes: manual playing alone, controlled playing alone, and collaborative playing; the chord selection button and accompaniment control button are used to assist in playing operations.
[0023] The trombone has three operating modes: manual playing, individual control playing, and collaborative playing, which are jointly controlled by the user and the trombone. In the mode switcher of the operation control unit of the above-mentioned playing module: when the trombone is selected to play manually, it can only be played manually; when the trombone is selected to play individually, it is handed over to the user to play; when the trombone is selected to play collaboratively, it is handed over to the user to control the collaborative playing.
[0024] In the standalone manual playing mode, the control module enables the playing module to directly respond to the player's breath pressure, tube position, and key combination operations for a certain period of time, driving the playing module to perform real-time audio synthesis and playback; In standalone playing mode, the user's mobile app downloads sheet music from the cloud platform and sends playing parameters and the piece to be played to the trombone's network module. The control module receives and parses the control commands and piece information from the user's mobile app, and controls the playing module to automatically synthesize and play audio, enabling automatic playing, as well as responding to control commands such as start, pause, and stop. The piece information mainly includes note numbers, note amplitude and duration, and information corresponding to the air pressure, pipe position, and key combination information collected by the playing module. In collaborative playing mode, the user's mobile app obtains the sheet music data corresponding to each trombone from the cloud platform and sends the playing parameters and the repertoire information to the network modules of each participating trombone. The control modules of each trombone receive and parse the concerto control commands from the user's mobile app, and the playing modules of each trombone play synchronously according to their assigned sheet music information, and respond to control commands such as start concerto, pause, and end concerto. The playing parameters and repertoire information obtained by each trombone can be different, so as to perform multi-part or differentiated playing.
[0025] A trombone instrument capable of network-connected ensemble playing can be played manually on its own. Step 1: Turn on the power. The trombone instrument enters standby mode, and each module (control module, network module, playing module) completes self-test.
[0026] Step 2: The user selects the manual playing mode on the trombone instrument, using the default or last set playing parameters.
[0027] Step 3: The playing module begins collecting air pressure, pipe position, and key information. The air pressure sensor collects breath pressure to control note loudness (amplitude) and duration; the pipe pressure sensor unit determines four reference pitches (C2, D2, E2, F2) using four preset pressure values; key combinations (fifth / chromatic / octave / transposition keys) are used for pitch adjustment; the system calculates the note number based on the current pipe position and key combinations, converts the air pressure signal amplitude into note volume, and the air pressure duration determines the note duration.
[0028] Step 4: The playing module calculates the note sequence number based on the pipe position and key combination, retrieves the timbre data of the corresponding note from the sound source unit, and then synthesizes the audio data of the note based on the corresponding amplitude and duration, driving the sound-producing unit to emit a sound of the corresponding amplitude and duration.
[0029] Step 5, repeat steps 3-5.
[0030] The following uses a mobile device as an example to illustrate the implementation process of individual control playing mode and collaborative playing mode. The user terminal device includes, but is not limited to, mobile phones and tablets.
[0031] A network-connected trombone instrument that allows for individual control during playing: Step 1: Turn on the power. The trombone instrument enters standby mode, and each module (control module, network module, playing module) completes self-test.
[0032] Step 2: The user selects the individual control playing mode on the trombone instrument and sets the playing parameters and the song to be played through the mobile APP.
[0033] Step 3: The mobile app downloads the sheet music from the cloud platform and sends the playing parameters and the piece to be played to the trombone's network module.
[0034] Step 4: The network module transmits the received information to the control module, which then forwards it to the playing module. This information primarily includes the note number, the amplitude and duration of the note, and the corresponding information from the playing module regarding air pressure, pipe position, and key combinations.
[0035] Step 5: The mobile app issues the command to start playback.
[0036] Step 6: The playing module retrieves the timbre data of the corresponding note from the sound source unit based on the note number in the obtained score information, and then synthesizes the audio data of the note according to the corresponding amplitude and duration, driving the sound-producing unit to emit a sound of the corresponding amplitude and duration.
[0037] Step 7, continue until the sheet music has finished playing or the mobile app issues a stop playback command.
[0038] The process of collaborative playing of a network-connected trombone instrument: Step 1: Turn on the power. The trombone instrument enters standby mode, and each module (control module, network module, playing module) completes self-test.
[0039] Step 2: The user selects the collaborative playing mode on the trombone instrument, and controls the user to select the trombone instrument to participate in the playing through the mobile APP, and set the playing parameters and the music to be played.
[0040] Step 3: Control the user's mobile app to retrieve the sheet music data for each trombone instrument from the cloud platform, and send the playing parameters and the repertoire information to the network module of each participating trombone instrument. Note that the playing parameters and repertoire information sent to each trombone instrument can be different, thus enabling multi-part or differentiated playing.
[0041] Step 4: The network module of each trombone instrument receives information and transmits it to the control module, which then forwards it to the playing module for processing. This information mainly includes the note number, the amplitude and duration of the note, and the corresponding information from the playing module regarding air pressure, pipe position, and key combinations.
[0042] Step 5: Control the user to issue a start playback command via the mobile APP.
[0043] Step 6: The playing module of each trombone instrument retrieves the timbre data of the corresponding note from the sound source unit according to the note number in the obtained score information, and then synthesizes the audio data of the note according to the corresponding amplitude and duration, driving the sound-producing unit to emit a sound of the corresponding amplitude and duration.
[0044] Step 7, continue until the sheet music has finished playing or the user issues a stop playback command via the mobile app.
[0045] The trombone instrument capable of network-connected concerto playing proposed in this invention has the following advantages: 1. Optimized playing method makes playing simple and easy to learn. Traditional trombones rely on the player adjusting the tube length by pushing and pulling, combined with lip muscle tension and breath control to achieve the target pitch. This physical sound production method requires specialized training to master the precise coordination of "tube length-lip vibration-embouchure," and pitch control is widely recognized as the most difficult among brass instruments. This design revolutionizes this logic through electronic modification: the tube position is detected by a sensor and corresponds to four reference pitches: C2 / D2 / E2 / F2; pitch expansion is achieved through combinations of fifth, semitone, and octave keys; the system uses an air pressure sensor to map the blow pressure into volume and note duration; thus, pitch control completely eliminates dependence on embouchure tension. This optimization frees the player from relying on lip muscle memory, allowing for stable output of the target pitch simply through the logical operation of "selecting a reference - pressing a combination - controlling airflow," transforming the muscle instinct that traditionally requires years of accumulation into digital rules that can be quickly mastered, significantly lowering the barrier to professional playing.
[0046] 2. It can collect playing data and perform intelligent evaluation. The collected playing information can be uploaded to the cloud to build a user playing database, which can then be used to measure playing accuracy and evaluate playing level.
[0047] 3. It features multiple playing modes. The single-hand manual playing mode achieves a traditional playing experience through electronic optimization, simplifying operation; the individual control playing mode supports preset playing parameters and sheet music information, enabling automated performance and complex repertoire arrangement; the collaborative playing mode supports multi-device cross-space synchronous multi-track ensemble playing, preserving the expressiveness of multi-part music while creating a new mode of multi-track music collaboration.
[0048] 4. Easy online collaboration and group formation. With the help of the networking module, users can connect multiple trombones and enjoy compatibility with various instruments. Real-time connection to the cloud platform enables multi-instrument collaboration. This allows for the formation of local online bands in communities, schools, and other locations, as well as the simulation of synchronized human-computer ensemble playing. It facilitates individual practice of ensemble pieces by individual players, promoting music social interaction and widespread popularization. Attached Figure Description
[0049] Figure 1 This is a system architecture block diagram of a trombone instrument capable of network-connected concerto playing according to this embodiment; Figure 2 This is a schematic diagram of the structure of a network-connected trombone concerto instrument according to this embodiment; Figure 3 This is a flowchart illustrating the process of implementing a network-connected concerto for a trombone instrument in this embodiment. Detailed Implementation
[0050] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, but the implementation of the present invention is not limited thereto.
[0051] like Figure 1 The diagram shown is a system architecture block diagram of a trombone instrument capable of network-connected concerto playing according to this embodiment, which includes a network module, a control module, and a playing module.
[0052] The networking module includes a communication unit and a human-computer interaction unit. The communication unit uses communication technologies such as 4G, 5G, WIFI, and Bluetooth to establish a communication connection with the user's terminal device. The user's terminal device (such as a mobile phone or tablet) obtains data from the cloud platform and forwards it to the networking module. The cloud platform stores and manages the sheet music resource library and timbre database. Each trombone instrument has a QR code with a unique local ID, allowing users to scan the code to log in to their account; the account information is linked to the cloud platform's user database.
[0053] The control module is responsible for the control and coordination of the entire system. The three modes—individual manual playing mode, individual control playing mode, and collaborative playing mode—are selected through the mode switch of the operation control unit. In the individual manual playing mode, the trombone can be played directly without user-end commands. The individual control playing mode and the collaborative playing mode require user-end commands or control user-end commands to take effect.
[0054] Users send instructions and data, including playing parameters, repertoire information, or concerto control commands, via applications on user-end devices such as mobile phones or tablets. These instructions and data are sent to the trombone's network module. The communication unit receives the instructions from the user or the controlling user, passes them to the human-computer interaction unit for parsing, and transmits the parsed information to the control module. The control module adjusts the operating mode of the playing module based on the parsed information and sends corresponding control commands to the playing module. In individual control playing mode, the control module receives and parses control commands and repertoire information from the user's mobile app, controls the playing module to play automatically, and responds to start, pause, and stop commands. In collaborative playing mode, the control modules of each trombone receive and parse concerto control commands from the controlling user's mobile app, and the playing modules of each trombone play synchronously according to their assigned playing parameters and repertoire information, and respond to start, pause, and stop commands. In individual manual playing mode, the control module enables the playing module to directly respond to the player's breath pressure, pipe position, and key combinations for a certain duration.
[0055] The playing module includes a sound source unit, a tube pressure sensing unit, a button unit, a breath control unit, a playing information acquisition and synthesis unit, a sound production unit, and an operation control unit. The sound source unit stores a traditional trombone tone library.
[0056] The tube pressure sensing unit has a built-in pressure sensor to detect pressure changes in four preset positions during playing. Each position corresponds to a reference pitch: Position 1: C2 (65.41Hz), Position 2: D2 (73.42Hz), Position 3: E2 (82.41Hz), Position 4: F2 (87.31Hz).
[0057] The key unit includes transposition keys, fifth keys, semitone keys, and two octave keys (an octave up key and an octave down key). The system achieves precise pitch control through the position of the tube and the keys. The functions of each key are as follows: (1) Transposition key: It needs to be used in combination with the octave key. In this case, the octave key is used as a transposition key to switch the reference pitch to other keys. Press the octave key to raise the pitch, such as C major to C# major. Press the octave key to lower the pitch, such as C major to B major, to achieve the switching of the reference pitch.
[0058] (2) After pressing the fifth key, assuming the current key is C, raise the current reference pitch by a perfect fifth, such as C2→G2, D2→A2, E2→B2, F2→C3.
[0059] (3) After pressing the semitone key, assuming the current key is C, raise the current pitch by a semitone, such as C2→C#2, D2→D#2, E2→F2, F2→F#2.
[0060] (4) After pressing the octave key, assuming the current key is C, raise the current pitch by one octave, such as C2→C3, D2→D3, E2→E3, F2→F3.
[0061] (5) After pressing the octave down key, assuming the current key is C, lower the current pitch by one octave, such as C2→C1, D2→D1, E2→E1, F2→F1.
[0062] The functions of each button can be used in combination, and the system achieves precise pitch control through the synergistic effect of the tube position and button combinations. An example is shown below, still assuming the current key is C: (1) Fifth key + semitone key: Raise the current reference pitch by a perfect fifth plus a semitone, such as C2→G#2, D2→A#2, E2→C2, F2→C#3.
[0063] (2) Fifth key + octave key: Raise the current reference pitch by a perfect fifth and an octave, such as C2→G3, D2→A3, E2→B3, F2→C4.
[0064] (3) Fifth key + octave lower key: raise the current reference pitch by a perfect fifth and lower it by an octave, such as C2→G1, D2→A1, E2→B1, F2→C2.
[0065] (4) Fifth key + octave key + semitone key: Raise the current reference pitch by a perfect fifth plus a semitone, and raise it by an octave, such as C2→G#3, D2→A#3, E2→C3, F2→C#4.
[0066] (5) Semitone key + octave key combination: raise the current reference pitch by a semitone and an octave, such as C2→C#3, D2→D#3, E2→F3, F2→F#3.
[0067] The breath inlet unit senses the blowing pressure through a pressure sensor and converts it into an electrical signal, which is then transmitted to the playing information acquisition and synthesis unit for processing, in order to precisely control the volume and duration of the notes played. In other words, the pressure sensor collects the loudness (amplitude) and duration of the notes.
[0068] The playing information acquisition and synthesis unit simultaneously collects three types of playing data: the breath port unit, the pipe pressure sensing unit, and the button unit. The breath port unit acquires the note's air pressure parameters: the note amplitude represented by air volume and the note duration represented by air blowing time. The pipe pressure sensing unit acquires the position of the corresponding C2 / D2 / E2 / F2 reference pitch. The button unit acquires the button combinations consisting of transposition keys, fifth keys, semitone keys, and octave keys. Based on the pipe position and button combinations, the playing information acquisition and synthesis unit determines the note number of the target pitch, retrieves the corresponding timbre data from the sound source unit, and combines it with the air pressure information to synthesize audio data, driving the sound unit to play it. The sound unit supports output from speakers, headphones, or Bluetooth speakers. Simultaneously, the target pitch note number and corresponding note air pressure parameters in the playing data can be uploaded to the cloud sequentially to build a user playing database, which is used to measure playing accuracy and evaluate playing level.
[0069] The operation control unit includes a power switch, volume adjuster, mode switcher, chord selection button, and accompaniment control button; the mode switcher refers to switching between three modes: manual playing alone, controlled playing alone, and collaborative playing; the chord selection button and accompaniment control button are used to assist in playing operations.
[0070] like Figure 2 The diagram shown is a structural schematic of a trombone instrument capable of network-connected concerto playing according to this embodiment.
[0071] The control module, networking module, and playing module's playing information acquisition and synthesis unit and sound source unit all adopt an integrated design, forming a central control hub 201.
[0072] The breath inlet unit 202 is integrated into the traditional mouthpiece position, and the built-in air pressure sensor directly collects the air pressure data for playing.
[0073] The tube pressure sensing unit 203 has a built-in tension and pressure sensor. By detecting the pressure changes of the tube at four preset positions, it corresponds to the four reference pitches C2, D2, E2, and F2 respectively.
[0074] The key unit 204 includes a fifth key 2041, a semitone key 2042, an octave-high key 2043, an octave-low key 2044, and a transposition key 2045. All the keys are concentrated in the hand position for easy two-handed operation.
[0075] The operation control unit 205 includes a power switch, volume adjuster, mode switcher, chord selection button, and accompaniment control button.
[0076] The sound unit 206 is built into the horn opening, and the horn structure is used to enhance the acoustic performance.
[0077] In this embodiment, the user terminal is illustrated by mobile phone 207. The user interacts with the cloud platform 208 through the mobile APP, and logs in to the account by scanning the QR code 209 of the trombone instrument. After that, the user can download sheet music resources and set playing parameters.
[0078] Figure 3 This is a flowchart illustrating the process of implementing networked concerto performance for a trombone instrument in this embodiment. The concerto steps are as follows: Step 1: Turn on the power. The trombone instrument enters standby mode, and each module (control module, network module, playing module) completes self-test.
[0079] Step 2: The user selects the collaborative playing mode on the trombone instrument, and controls the user to select the trombone instrument to participate in the playing through the mobile APP, and set the playing parameters and the music to be played.
[0080] Step 3: Control the user's mobile app to retrieve the sheet music data for each trombone instrument from the cloud platform, and send the playing parameters and the repertoire information to the network module of each participating trombone instrument. Note that the playing parameters and repertoire information sent to each trombone instrument can be different, thus enabling multi-part or differentiated playing.
[0081] Step 4: After receiving the information, the network module of each trombone instrument transmits it to the control module, which then forwards it to the playing module. This information mainly includes the note number, the amplitude and duration of the note, and the corresponding information from the playing module regarding air pressure, pipe position, and key combinations.
[0082] Step 5: Control the user to issue a start playback command via the mobile APP.
[0083] Step 6: The playing module of each trombone instrument retrieves the timbre data of the corresponding note from the sound source unit according to the note number in the obtained score information, and then synthesizes the audio data of the note according to the amplitude and duration corresponding to the air pressure information, driving the sound unit to emit a sound of the corresponding size and duration.
[0084] Step 7, continue until the sheet music has finished playing or the user issues a stop playback command via the mobile app.

The human-computer interaction unit receives playing parameter information or playing repertoire information set by the user, including but not limited to timbre and rhythm, and transmits the above information to the control module. The control module controls the audio synthesis of the playing module according to the received playing parameter information. The term "user" refers to a general user who communicates with the network module via an app on their mobile phone or tablet, including sending playing parameter information or repertoire information. The term "control user" refers to an advanced user who also uses an app on their mobile phone or tablet to control the networked concerto of trombone instruments. It is used for concerto control of multiple trombone instruments. It can control multiple trombone instruments, send playing parameter information or repertoire information, and issue control commands such as start concerto, pause, end, and concerto content to control the collaborative work of multiple trombone instruments.
4. A trombone instrument capable of network-connected concerto playing according to claim 1, characterized in that, The playing module includes a sound source unit, a breath port unit, a tube pressure sensing unit, a button unit, a playing information acquisition and synthesis unit, a sound generation unit, and an operation control unit. It mainly collects the playing information of the user through sensors, and then synthesizes audio in real time based on the playing information and the timbre library to drive the sound generation unit to play. The sound source unit of the playing module is a timbre library for storing traditional trombone instruments, used to store and manage timbre data downloaded from the user terminal.
5. A trombone instrument capable of network-connected concerto playing according to claim 4, characterized in that, The breath port unit of the playing module has a built-in air pressure sensor that can sense the pressure of the breath blown by the player in real time and convert these physical quantities into electrical signals, which are then transmitted to the playing information acquisition and synthesis unit for processing, so as to accurately control the volume and duration of the notes played.
6. A trombone instrument capable of network-connected concerto playing according to claim 4, characterized in that, The pipe-pulling pressure sensing unit of the playing module has a built-in pressure sensor. By detecting the pressure changes of the pipe at four preset positions, it corresponds to four reference pitches: international standard pitch C2 (65.41Hz), D2 (73.42Hz), E2 (82.41Hz), and F2 (87.31Hz).
7. A trombone instrument capable of network-connected concerto playing according to claim 4, characterized in that, The key unit of the playing module includes a fifth key, a semitone key, two octave keys, and a transposition key: the fifth key raises the current reference pitch by a perfect fifth; the semitone key raises the current reference pitch by a semitone; the two octave keys are an octave raise key and an octave lower key; the transposition key is used to switch the reference pitch to other keys, with the default being C major. The transposition key must be used in combination with the octave key. In this case, the octave key acts as a transposition switch key. Pressing the up octave key triggers an up pitch, and pressing the down octave key triggers a down pitch. With the tube in any position, the player can adjust the pitch by combining the fifth, semitone, and octave keys. The functions of each key can be used in combination, and the system achieves precise pitch control through the combined action of the tube position and key combinations.
8. A trombone instrument capable of network-connected concerto playing according to claim 4, characterized in that... The playing module's playing information acquisition and synthesis unit simultaneously acquires three types of playing data: the breath port unit, the tube pressure sensing unit, and the button unit. The breath port unit obtains the note's air pressure parameters: the note's amplitude represented by the amount of air and the note's duration represented by the duration of the breath. The tube pressure sensing unit obtains the position of the corresponding C2 / D2 / E2 / F2 reference pitch. The button unit then obtains button combinations consisting of transposition keys, fifth keys, semitone keys, and octave keys. The playing information acquisition and synthesis unit performs real-time audio synthesis based on the above three types of playing data: the note number of the target pitch is determined according to the pipe position and key combination, then the corresponding timbre data is retrieved from the sound source unit, and the audio signal is synthesized in real time in combination with the air pressure parameters to drive the sound unit to output sound effects; Meanwhile, the target pitch note number and the corresponding note air pressure parameters in the playing data constitute the playing information, which is uploaded to the cloud in chronological order to build a user playing database, thereby measuring playing accuracy and evaluating playing level.
9. A trombone instrument capable of network-connected concerto playing according to claim 4, characterized in that... The sound-generating unit of the playing module plays the synthesized audio data; the operation control unit includes a power switch, volume adjuster, mode switcher, chord selection button and accompaniment control button, etc.; the mode switcher refers to switching between three modes: manual playing alone, controlled playing alone, and collaborative playing; the chord selection button and accompaniment control button are used to assist in the playing operation.
10. A trombone instrument capable of network-connected concerto playing according to claim 2, characterized in that... The trombone has three operating modes: manual playing, individual controlled playing, and collaborative playing, which are jointly controlled by the user and the trombone. In the mode switcher of the operation control unit of the playing module: when the trombone is selected to play manually, it can only be played manually; when the trombone is selected to play individually controlled, it is handed over to the user to play; when the trombone is selected to play collaboratively, it is handed over to the user to control the collaborative playing. In the standalone manual playing mode, the control module enables the playing module to directly respond to the player's breath pressure, tube position, and key combination operations for a certain period of time, driving the playing module to perform real-time audio synthesis and playback; In standalone playing mode, the user's mobile app downloads sheet music from the cloud platform and sends playing parameters and the piece to be played to the trombone's network module. The control module receives and parses the control commands and piece information from the user's mobile app, and controls the playing module to automatically synthesize and play audio, enabling automatic playing, as well as responding to control commands such as start, pause, and stop. The piece information mainly includes note numbers, note amplitude and duration, and information corresponding to the air pressure, pipe position, and key combination information collected by the playing module. In collaborative playing mode, the user's mobile app obtains the sheet music data corresponding to each trombone from the cloud platform and sends the playing parameters and the repertoire information to the network modules of each participating trombone. The control modules of each trombone receive and parse the concerto control commands from the user's mobile app, and the playing modules of each trombone play synchronously according to their assigned sheet music information, and respond to control commands such as start concerto, pause, and end concerto. The playing parameters and repertoire information obtained by each trombone can be different, so as to perform multi-part or differentiated playing.
