[0043] Figure 1 The structure schematic diagram of a split combined type intelligent musical instrument provided for the embodiment of the utility model, reference Figure 1The split combined type intelligent musical instrument provided by the embodiment of the utility model includes a host 10 and at least one accessory 20. The host 10 includes a host circuit board 11 and a first touch module 12, and the host circuit board 11 includes a master control chip 111. The accessory 20 includes an accessory circuit board 21 and a playing module 22, and the accessory circuit board 21 includes a second touch module 211. The host circuit board 11 and the accessory circuit board 21 are pluggable connected. The first touch signal input end of the master control chip 111 is electrically connected with the first touch signal output end of the first touch module 12, and is used for receiving the first touch signal output by the first touch module 12. The second touch signal input end of the master control chip 111 is electrically connected with the second touch signal output end of the second touch module 211, and is used for receiving the second touch signal output by the second touch module 211. The playing signal output end of the master control chip 111 is electrically connected with the playing signal input end of the playing module 22, and is used for outputting the playing signal to the playing module 22.

[0044] For example, the host circuit board 11 and the accessory circuit board 21 can be connected or separated through the electric interface of the plug-in structure. As a feasible implementation manner, the host 10 further includes a first pair of plug connectors 13. The first pair of plug connectors 13 are electrically connected with the host circuit board 11. The accessory 20 further includes a second pair of plug connectors 23. The second pair of plug connectors 23 are electrically connected with the accessory circuit board 21. The first pair of plug connectors 13 and the second pair of plug connectors 23 are pluggable connected.

[0045] The first touch signal output end of the first touch module 12 can be electrically connected with the first touch signal input end of the master control chip 111 when the first pair of plug connectors 13 and the second pair of plug connectors 23 are connected together, and then the first touch signal sensed by the first touch module 12 can be transmitted to the master control chip 111. As a feasible implementation manner, the first touch module 12 includes a touch display screen. Figure 2 A split combined type intelligent musical instrument provided by the embodiment of the utility model, Figure 3 A split combined type intelligent musical instrument provided by the embodiment of the utility model, Figure 2 And Figure 3The first touch module 12 shown is a long strip-shaped display screen module with full lamination and capacitive touch function. When the host is powered on, the long strip-shaped touch display screen can display the home page of the application software related to musical instrument performance. The user can select the musical instrument interface matched with the accessory 20 by touching the long strip-shaped touch display screen. For example, if the shell of the accessory 20 imitates the shape of the lower half of a traditional wooden guitar, and the second touch module 211 of the accessory 20 imitates the strings of a traditional wooden guitar, the user can control the long strip-shaped touch display screen to display the user interface (UI interface) of the left-hand fingerboard of the wooden guitar. It should be noted that the above-mentioned application software is run according to the host control chip 111 with an android or Linux system. The host control chip 111 can be selected from RK3566 or PX30 and above specifications.

[0046] It should also be noted that the long strip-shaped touch display screen is preferably a 11.9-inch 1480*320 long strip screen. The screen is an IPS full-view LCD display, and the full lamination process makes the display effect excellent. When the guitar performance posture is similar, a slight tilt can clearly see the screen. If the length is less than this length, the operation interface is too small, and the simulation performance experience is not good, or even the musical instrument performance posture cannot be completely restored. If the length is very long, not only the cost will increase, but also the simulation degree of some musical instruments will be affected. In general, a long strip screen must be used, and the aspect ratio of about 4.7:1 is more appropriate.

[0047] The second touch signal input end of the second touch module 211 can be electrically connected to the second touch signal input end of the host control chip 111 when the first and second plug-in connectors 13 and 23 are connected together, and then the second touch signal sensed by the second touch module 211 can be transmitted to the host control chip 111. As a feasible implementation, the second touch module 211 includes a plurality of capacitive touch modules. It should be noted that the number of capacitive touch modules corresponding to different types of accessories is different. For example, the accessory 20 imitating the shape of a guitar has six protruding capacitive touch modules to imitate the six strings of a guitar. The capacitive touch module is generally composed of a mainboard with a capacitor and a capacitive touch chip tightly attached by conductive silicone or conductive rubber. For example, the accessory 20 imitating the shape of a zither has 21 protruding capacitive touch modules to imitate the 21 strings of a zither.

[0048] The master control chip 111 can output corresponding playing signals to the playing module 22 according to the first touch signal and the second touch signal after receiving the first touch signal and the second touch signal, so as to emit sound. Taking a guitar as an example, when the user's left hand presses the position of a certain string of the simulated wooden guitar fingerboard of the UI interface displayed by the first touch module 12, the first touch module 12 will transmit the detected electric signal (voltage signal or current signal), that is, the first touch signal, to the master control chip 111, and the master control chip 111 will process the first touch signal after receiving the first touch signal, so as to convert the first touch signal into a first touch signal containing the number of the sounding string and the pitch information. When the user's right hand touches or plucks the raised part simulating the string, that is, the second touch module 211, the second touch module 211 will transmit the detected electric signal (for example, a capacitance signal), that is, the second touch signal, to the master control chip 111, and the master control chip 111 will process the second touch signal after receiving the second touch signal, so as to convert the second touch signal into a second touch signal containing the number of the string and the mute information. If the same string number is detected in the first touch signal and the processed second touch signal, the playing information corresponding to the string number will be output to the playing module 22.

[0049] In other possible embodiments, the second touch signal output by the second touch module 211 will not be directly transmitted to the master control chip 111 for processing. Figure 4 Another structure schematic view of the split combined intelligent musical instrument is provided for the embodiments of the utility model, referring to Figure 4 The accessory circuit board 21 further comprises a micro control unit 213. The micro control unit 213 is electrically connected with the second touch signal output end and the second touch signal input end respectively, is used for processing the second touch signal, and transmits the processed second touch signal to the master control chip 111. Figure 4 In the utility model embodiment shown in the figure, the second touch signal output by the second touch module 211 will be first transmitted to the micro control unit 213, and the micro control unit 213 will convert the electric signal second touch signal directly output by the second touch module 211 into the second touch signal containing the number of the string and the mute information, and transmit the converted second touch signal to the master control chip 111, so as to reduce the data processing pressure of the master control chip 111, and be beneficial to improving the working efficiency of the master control chip 111. It should be noted that the micro control unit 213 in the embodiments of the utility model can select st103, st405 or MCU with similar performance.

[0050] Take the example of a wind instrument, the host 10 and the accessory 20 in the shape of a wind instrument are plugged together. The first touch module 12 will display the interface of the simulated keys of the wind instrument to be played, meeting the pressing needs of the four fingers of both hands. Some accessories 20 in the shape of a wind instrument will also have multiple capacitive touch modules, meeting the pressing needs of the thumbs of both hands. The accessory 20 in the shape of a wind instrument will also contain a mouthpiece module with a built-in vibration sensor, usually made of a piezoelectric sensor or a pressure sensor. When the user blows air into the mouthpiece module with the mouth, the airflow will impact the vibration or pressure sensor, generating an electrical signal change. The micro control unit 213 of the accessory 20 will calculate and process the signal exceeding the set threshold as the state information of the sound to be played, and send it to the host control chip 111 of the host 10. Combined with the keys on the user interface and the capacitive touch modules on the accessory 20, these signals are processed by software as pitch information, and the sound will be played after pressing, and the sound will stop playing when the user completely releases or stops blowing air.

[0051] Take the example of a string instrument, the host 10 and the accessory 20 in the shape of a violin are plugged together. The first touch module 12 will display the simulated interface of the fingerboard of the violin to be played, meeting the needs of the left hand pressing the fingerboard strings. The accessory 20 in the shape of a violin has four raised parts simulating strings, which is the same as the accessory of a guitar. Touching with fingers or using a conductive accessory simulating a violin bow will change the electrical signal, and the micro control unit 213 will send the string number and sound state information to the host control chip 111 of the host 10, and then combine the string number and pitch information mapped by the left hand pressing position to produce sound.

[0052] The accessories of a piano, an electronic organ and a drum are plugged together with the host. The host has a black and white key interface or a drum interface, while the accessory has various structural systems of keys or electronic drum surfaces for finger pressing or knocking. The signals are processed by the micro control unit 213 of the accessory 20 and sent to the host control chip 111 of the host 10 to produce sound or stop sound.

[0053] It should be noted that the final output of the host control chip is the playback signal retrieved from the storage module. Specifically, refer to Figure 1 and Figure 4The host circuit board 11 further comprises a storage module 113. The storage module 113 is configured to store a wave table file, wherein the wave table file comprises a plurality of musical instrument sound sample data. The retrieval request signal output end of the host chip 111 is electrically connected to the retrieval request signal input end of the storage module 113, and is configured to output a retrieval request signal to the storage module 113. The musical instrument sound sample data input end of the host chip 111 is electrically connected to the musical instrument sound sample data output end of the storage module 113, and is configured to receive the musical instrument sound sample data output by the storage module 113. After the host chip 111 detects that the first touch signal and the processed second touch signal have the same string number, the host chip 111 outputs a retrieval request signal to the storage module 113. After receiving the retrieval request signal, the storage module 113 transmits the sound sample data corresponding to the string number to the host chip 111.

[0054] The technical scheme of the embodiment of the utility model, through setting up host computer 10 in main control circuit board 11 and accessory 20 in accessory circuit board 21 of accessory 20 are pluggable connection, namely host computer 10 can and multiple accessories 20 connection constitutes multiple musical instruments, not only simple structure, moreover can through giving different accessory corresponding shell to make the appearance of the combined musical instrument more close to real musical instrument, be favorable to improve user experience, and the most costly part is as host computer 10, using split to plug mode, only change different low -cost accessory 20, can expand the simulation performance of possessing more kinds of musical instruments.

[0055] Compared with traditional musical instruments, the left hand part of the plucking and stringed musical instruments in the traditional musical instruments is simulated by software, and the key area of the double hands of the wind instrument is also simulated by software. The other part of the operation simulation is solved by using the controller and the sound box integrated pluggable accessory. The intelligent virtual musical instrument interface experience of the host computer 10 and the physical interaction operation experience of the accessory 20 are combined to achieve the approximate restoration of the real feeling of the traditional musical instruments, share one host computer 10, and realize the simulation performance of multiple musical instruments by plugging different accessories 20. The restoration degree is high, the cost is the lowest, and the cost performance effect is obtained.

[0056] Compared with the simulation musical instrument mode of pure software, the split combination type intelligent musical instrument provided by the utility model has the performance experience of the real musical instrument, and even can directly restore the finger method and performance posture of using the real musical instrument. In addition to the sound, the utility model also has the action effect of stage performance. The performer and the audience can obtain better happiness and immersion experience.

[0057] Compared with electronic electric musical instruments, although some specifications and size simulation restoration degrees are sacrificed, effects and multi-tone playing can also be completed through software, and because pure software sound sources are used, there are absolute advantages in tone expansion, large capacity and high quality tone, and the traditional electric musical instruments are based on specific DSP chips and small capacity storage devices for sound generation, and the expansion is limited. And compared with traditional musical instruments and electronic electric musical instruments, it also has the characteristics of small size and easy to carry, and is more popular among music lovers.

[0058] Compared with the modern way of playing and interacting through the connection of mobile phone app and musical instrument host through Bluetooth. The advantage of the split combined intelligent musical instrument provided by the utility model lies in that the long screen can display music scores, lyrics, accompaniment and other information by using part of the display area, all information display and interaction functions that can be realized by all apps can be completed by the host, and it is not necessary to download mobile phone apps. And the negative experience of turning head and switching sight line, affecting the continuity of playing, is completely avoided. The host transmits data and audio signals through internal wired connection, and there is almost no delay, while the musical instruments connected in the way of mobile phone app have a certain degree of delay, especially the mobile phone app itself makes sound wave table and audio playing transmission to the musical instrument loudspeaker playing, and the current technology is almost impossible to be lower than 60ms, which is unacceptable delay for players. And pre-storing sound wave table and audio playing source files on the musical instrument needs special chips and storage cards, and the cost increases more. In addition, the app needs to be adapted to mobile phones or tablets, and there are compatibility problems for some models, so it cannot be used smoothly, and many customer service interventions are needed, and even users need to replace mobile phones to use normally. The split combined intelligent musical instrument provided by the utility model does not have compatibility problems.

[0059] The split combined intelligent musical instrument provided by the utility model supports a certain degree of opening, for example, the touch keys and RGB lights of accessories have packaged APIs, and developers can be called to develop, for example, compatible with third-party mainstream musical instrument learning software, light prompts the part to be played, or error correction prompts, and the third-party software can also make payment functions of value-added functions or services, for example, a two-dimensional code for subscription payment is displayed in the host screen. Forming a small ecological mode of host plus industry software developers, more diversified learning, entertainment and game applications are provided for users. Not only can it meet the use of general players, but also can expand students to use musical instruments and music, and game lovers to play music games, greatly expanding the customer group and business value.

Taking the accessory 20 in the shape of an imitation guitar as an example, the indication module 214 includes six RGB lamps, and the six RGB lamps correspond one by one to the capacitive touch modules imitating six strings of a guitar. Taking the accessory 20 in the shape of an imitation guzheng as an example, the indication module 214 includes 21 RGB lamps, and the 21 RGB lamps correspond one by one to the capacitive touch modules imitating 21 strings of a guzheng.
