[0049] First embodiment

[0050] In the embodiments of this application, Figure 1 and Figure 3 As shown, the intelligent accordion includes a shell 1, a speaker 6, a plurality of scale buttons 2 and a protective cover 3. The speaker 6 is arranged on the shell 1; the plurality of scale buttons 2 are arranged on the shell 1, and the plurality of scale buttons 2 are electrically connected to the speaker 6. When the scale buttons 2 are triggered individually or in combination, different scale signals are sent to the speaker 6. After receiving the scale signal, the speaker 6 emits the corresponding scale sound; the protective cover 3 is mounted on the shell 1 and covers the plurality of scale buttons 2.

[0051] Specifically, the smart accordion proposed in this application also includes a controller installed inside the shell 1, and the controller is used to transmit signals between the scale keys 2 and the speaker 6. Specifically, the smart accordion also includes necessary components such as a power supply, which will not be described in detail here.

[0052] It is worth noting that the scale button 2 can be triggered by being pressed or touched, each scale button 2 corresponds to a scale signal, and the multiple scale buttons 2 have multiple combined pressing modes. For example, when any two scale buttons 2 among the multiple scale buttons 2 are pressed or touched at the same time and triggered, a specific scale signal can be generated. When any three, four or five scale buttons 2 among the multiple scale buttons 2 are pressed or touched at the same time and triggered, a specific scale signal can also be generated. For ease of understanding, an embodiment is used for explanation below. In this embodiment, there are five scale buttons 2 in total, and the five buttons correspond to the five fingers on the user's hand one by one. How the five scale buttons 2 are combined to achieve the sounding of 31 scales when pressed or touched by five fingers can be shown in the following table:

[0053] Specifically, referring to Table 1, after the scale button on the smart accordion is triggered, the corresponding scale can be found according to the current key signal based on the preset key signal-scale mapping table.

[0054]

[0055]

[0056] Table 1. Key signal-scale mapping table, where the thumb, index finger, middle finger, ring finger and little finger in the table refer to the scale keys corresponding to the human fingers, and the combination of "thumb + index finger" means that the two scale keys are triggered at the same time.

[0057] In this way, when the user presses or touches the scale button 2 through the music score, not only can the finger rehabilitation training be performed, but also different songs can be played with the smart harp. That is, the smart harp of the present application increases the fun of finger rehabilitation training.

[0058] It is worth noting that in some embodiments, when the multiple scale buttons 2 of the intelligent accordion are triggered individually or in combination, different pre-stored song signals or pre-stored crosstalk signals can also be sent to the speaker 6. After receiving the pre-stored song signal, the speaker 6 plays the corresponding pre-stored song, and after receiving the pre-stored crosstalk signal, it plays the corresponding pre-stored crosstalk. The design of this application is not limited to this.

[0059] It is understandable that existing accordion instruments have the problem of monotonous gameplay. To address this problem, the scale buttons 2 of the smart accordion of the present invention can be triggered individually or in combination to obtain corresponding scale signals. Based on the scale signals, corresponding scale sounds are obtained and then played through the speaker 6. In this way, the different combination triggering methods of the multiple scale buttons 2 enrich the playing methods of the smart accordion. At the same time, the user can also perform finger rehabilitation or exercise by pressing the scale buttons 2. Specifically, the smart accordion of the present invention also has a protective cover 3 placed on the outside of the housing 1 and covers the multiple scale buttons 2. This effectively prevents dust from contaminating the scale buttons 2 or the housing 1, and prevents sweat from the user's hands from interfering with the normal operation of the scale buttons 2 or the housing 1. It can be seen that compared with existing instruments for disease prevention or rehabilitation of finger exercises, the smart accordion of the present invention has the advantages of high fun, high reliability and strong operational stability.

[0060] Alternatively, as Figure 3 and Figure 4 As shown, the protective cover 3 is an integrated design. It is understood that this configuration is conducive to improving the stability of the overall structure of the protective cover 3, and is conducive to preventing external environmental factors (such as dust, water, etc.) from entering the interior of the housing 1 through the connection gap between the scale keys 2 and the housing 1, thereby improving the stability and reliability of the smart accordion. In addition, the integrated structural design is also conducive to improving the overall appearance of the product and enhancing the user experience.

[0061] Alternatively, as Figure 1 As shown, the protective cover 3 is provided with a plurality of pressing portions 31 corresponding one-to-one to the plurality of scale keys 2. It can be understood that the pressing portions 31 can serve as an identification function. When installing the protective cover 3, the user can complete the correct assembly of the protective cover 3 by the positional correspondence between the pressing portions 31 and the scale keys 2. After the protective cover 3 is installed, that is, during the daily use of the smart harp, the user can also use the pressing portions 31 to quickly find the position of the scale keys 2, thereby improving the user experience. Furthermore, in this embodiment, the pressing portions 31 are arranged to protrude from the inner side of the protective cover 3 to the outer side to form a clearance space for accommodating the scale keys 2.

[0062] Optionally, the protective cover 3 is made of a skin-friendly material. It is understood that such a configuration is conducive to improving the feel of the product and enhancing the user experience. It is worth noting that the design of this application is not limited to this. In other embodiments, the protective cover 3 can also be made of other materials, such as, but not limited to, plastic, silicone, rubber, or silicone rubber, and there is no limitation to this.

[0063] Alternatively, asFigure 3 As shown, there are five scale buttons 2. It is understood that the five scale buttons correspond to the number of fingers on a human hand, making it convenient for the user to play the smart harp with one hand. Of course, in other embodiments, the scale buttons 2 can also be specifically set to other numbers, such as two, three, four, six, etc.

[0064] Alternatively, as Figure 1 As shown, the shell 1 includes a first end 11 and a second end 12 that are arranged opposite to each other, and four of the five scale keys 2 are arranged at intervals between the first end 11 and the second end 12, and the four scale keys 2 are arranged on the same side of the shell 1. Here, the four scale keys 2 are arranged on the same side of the shell 1, which means that the shell 1 is divided into two shells under the cutting of the same dividing line, and the four scale keys 2 are all located on the same one of the two shells. It can be understood that the four scale keys 2 are respectively used to correspond to the index finger, middle finger, ring finger and little finger on the same hand of the user. The four scale keys 2 are arranged at intervals on the same side of the shell 1, which is conducive to making the arrangement of the scale keys 2 more ergonomically designed and improving the comfort of the user. Preferably, the four scale keys 2 are arranged at intervals in the same straight line between the first end 11 and the second end 12.

[0065] Alternatively, as Figure 3 As shown, another scale button 2 among the five scale buttons 2 is located at the first end 11. The scale button 2 located at the first end 11 is used to correspond to the thumb on the user's hand. Combined with the arrangement of the four scale buttons 2 described above, it can be understood that when the user holds the smart accordion, the user's thumb is placed on the first end 11, while the index finger, middle finger, ring finger, and little finger are located on the side of the housing 1. This arrangement, on the one hand, facilitates the user's hand to form a force gesture to hold the smart accordion tightly. In other words, it is convenient for the user to hold the smart accordion with one hand, facilitates the user to perform one-handed rehabilitation training, and improves the practicality of the product. At the same time, the five scale buttons 2 of the present application are arranged in this way to meet the usage needs of users with different hands. That is, the user can hold the smart accordion with either the left hand or the right hand for training. It should be noted that the design of the present application is not limited to this. In other embodiments, the five buttons can also be arranged between the first end 11 and the second end 12.

[0066] Alternatively, as Figures 2 to 4As shown, the second end portion 12 is provided with a sound outlet 13, and the protective cover 3 is provided with a hollow area 32 corresponding to the sound outlet 13. It can be understood that the position of the speaker 6 facing the sound outlet 13 is set inside the shell 1. Since the second end portion 12 is on the side of the smart accordion away from the user when the user holds the smart accordion, that is, the user will not touch the second end portion 12 during use. Therefore, the sound outlet 13 is provided at the second end portion 12, which can effectively avoid the situation where the sound outlet 13 is blocked when the user holds the smart accordion, thereby ensuring that the product has a better sound effect. It is worth noting that in the design of this application, there is no restriction on the shape of the initial sound port. It can be set in a cylindrical shape, or in a column shape, a cone shape, or the like.

[0067] Alternatively, as Figure 4 As shown, the smart accordion includes function keys 4 disposed on the housing 1. The function keys 4 include at least one of the following: an on / off key 41, a volume key 42, an instrument switch key 43, a practice mode key 44, and an entertainment mode key 45. A protective cover 3 is disposed on the outside of the function keys 4. It will be appreciated that the use of the protective cover 3 covering the outside of the function keys 4 helps prevent external environmental factors (such as dust, water, etc.) from entering the interior of the housing 1 through the connection gap between the function keys 4 and the housing 1, thereby improving the stability and reliability of the smart accordion. Specifically, the function keys 4 include an on / off key 41, a volume key 42, an instrument switching key 43, a practice mode key 44, and an entertainment mode key 45. The on / off key 41 is used to turn the smart accordion on and off, the volume key 42 is used to increase or decrease the volume of the smart accordion, the instrument switching key 43 is used to switch the type of instrument simulated by the smart accordion, the practice mode key 44 is used to switch the smart accordion to the practice mode (the user can practice playing by pressing the scale key 2 in the practice mode), and the entertainment mode key 45 is used to switch the smart accordion to the entertainment mode (the user can practice playing by pressing the scale key 2 in the entertainment mode). 2 for entertainment), the power key 41, volume key 42, instrument switching key 43, practice mode key 44 and entertainment mode key 45 are all arranged between the first end 11 and the second end 12, and in order to avoid the position of the scale key 2, the function key and the four scale keys 2 are respectively arranged on the opposite sides of the shell 1. Furthermore, in order to prevent the user from accidentally touching the power key 41 during rehabilitation training, in this embodiment, the exposed end of the power key 41 facing away from the inside of the shell 1 does not protrude from the outer surface of the shell 1, and the protective cover 3 is provided with a recessed portion 33 corresponding to the exposed end of the power key 41. Without loss of generality, in order to facilitate the user to identify and judge the volume reduction, in this embodiment, the protective cover 3 is provided with a "+" mark corresponding to the volume plus key of the volume key 42, and a "-" mark corresponding to the volume minus key of the volume key 42. Specific characters are also provided for the corresponding instrument switching key 43, practice mode key 44 and entertainment mode key 45. For details, refer to Figure 4 , so that it is easy for users to identify and recognize the corresponding ones.

[0068] Alternatively, as Figure 4 As shown, the smart accordion further includes a charging port 5 provided on the housing 1, and the protective cover 3 includes a protective cover 34 provided at the opening of the charging port 5, and the protective cover 34 can be opened or closed relative to the charging port 5. It can be understood that the use of the protective cover 34 to cover the charging port 5 can effectively prevent external environmental factors (such as dust, water, etc.) from entering the interior of the housing 1 through the charging port 5, thereby improving the stability and reliability of the smart accordion.

[0069] Optionally, the multiple scale buttons 2 are all pressure buttons. It is understood that the use of pressure buttons can provide more tactile feedback while the user is undergoing rehabilitation training, and can also effectively reduce the cost of manufacturing and maintaining the scale buttons 2. It is worth noting that the design of the present application is not limited to this. In other embodiments, the multiple scale buttons 2 can also be touch buttons.

[0070] Alternatively, as Figure 1 or Figure 2 As shown, the housing 1 is ellipsoidal. It is understood that with this configuration, the ellipsoidal outer surface does not have sharp corners that would cause discomfort to the user's hand, allowing the housing 1 to better fit the user's palm, providing the user with a better user experience. Of course, the design of this application is not limited to this. In other embodiments, the housing 1 can also be specifically other shapes, such as, but not limited to, a cylindrical shape, a spherical shape, etc.

[0071] like Figure 5 As shown, Figure 5 It is a module structure diagram of the intelligent accordion in the hardware operating environment involved in the embodiment of the present invention.

[0072] like Figure 5 As shown, the intelligent hand accordion 1 includes a memory 71 , a processor 72 and a network interface 73 .

[0073] The memory 71 includes at least one type of readable storage medium, such as a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., an SD or DX memory), a magnetic memory, a magnetic disk, an optical disk, etc. In some embodiments, the memory 71 can be an internal storage unit of the intelligent accordion, such as the hard disk of the intelligent accordion. In other embodiments, the memory 71 can also be an external storage device of the intelligent accordion, such as a plug-in hard disk equipped on the intelligent accordion, a smart memory card (SMC), a secure digital (SD) card, a flash card, etc.

[0074] Furthermore, the memory 71 may include an internal storage unit of the intelligent accordion and an external storage device. The memory 71 may be used not only to store application software installed in the intelligent accordion 1 and various data, such as the code of the intelligent accordion control program 70, but also to temporarily store data that has been output or is about to be output.

[0075] In some embodiments, the processor 72 may be a central processing unit (CPU), a controller, a microcontroller, a microprocessor, or other data processing chip, configured to execute program codes stored in the memory 71 or process data, such as executing the control program 70 of the intelligent accordion.

[0076] The network interface 73 may include a standard wired interface or a wireless interface (such as a WI-FI interface), and is generally used to establish a communication connection between the intelligent accordion 1 and other electronic devices.

[0077] The network may be the Internet, a cloud network, a wireless fidelity (Wi-Fi) network, a personal area network (PAN), a local area network (LAN), and / or a metropolitan area network (MAN). Various devices in the network environment may be configured to connect to the communication network according to various wired and wireless communication protocols. Examples of such wired and wireless communication protocols may include, but are not limited to, at least one of the following: Transmission Control Protocol and Internet Protocol (TCP / IP), User Datagram Protocol (UDP), Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), ZigBee, EDGE, IEEE 802.11, Light Fidelity (Li-Fi), 802.16, IEEE 802.11s, IEEE 802.11g, multi-hop communication, wireless access point (AP), device-to-device communication, cellular communication protocol, and / or Bluetooth communication protocol, or a combination thereof.

[0078] Optionally, the intelligent accordion 1 may further include a user interface, which may include a display and an input unit such as a keyboard. Optional user interfaces may also include standard wired interfaces and wireless interfaces. Optionally, in some embodiments, the display may be an LED display, a liquid crystal display, a touch-sensitive liquid crystal display, or an OLED (Organic Light-Emitting Diode) touchscreen. The display may also be referred to as a display screen or a display unit, and is used to display information processed in the intelligent accordion 1 and to display a visual user interface.

[0106] After receiving the third preset practice instruction, if a switching instruction based on the third scale key is received from the user, the practice track is switched;

[0107] After the practice track is switched, if a confirmation instruction based on the user pressing the fourth scale key is received, the current practice track will be played as the preset practice track.

[0108] In one embodiment, the processor 72 may be configured to call the control program of the intelligent accordion stored in the memory 71 and perform the following operations:

[0109] The control method of the intelligent accordion further comprises:

[0110] When receiving the instrument change instruction based on the fifth scale key pressed by the user, the sound-generating instrument currently simulated by the intelligent accordion is switched.

[0111] Based on the hardware architecture of the intelligent accordion control device, an embodiment of the intelligent accordion control method of the present invention is proposed. The intelligent accordion control method of the present invention is intended to achieve a miniaturized design of the accordion instrument.

[0112] Reference Figure 6 , Figure 6 This is an embodiment of the control method of the intelligent accordion of the present invention, and the control method of the intelligent accordion comprises the following steps:

[0113] S10. When the scale keys are triggered individually or in combination, corresponding key signals are generated.

[0114] Specifically, when a scale button on the smart accordion is triggered, a corresponding key signal is generated. The scale buttons on the smart accordion can be triggered individually or in combination (i.e., the user triggers at least two buttons simultaneously). When the scale buttons on the smart accordion are triggered in combination, only one scale signal is generated.

[0115] S20: Acquire a musical scale corresponding to the key signal.

[0116] Specifically, the user can learn Table 1 above to input different scales on the smart accordion.

[0117] S30, controlling the speaker of the intelligent accordion to play the scale.

[0118] Specifically, after determining the musical scale corresponding to the current key signal, the speaker of the intelligent accordion can be controlled to play the musical scale, so that the scale can be played while the user presses the scale key.

[0119] It can be understood that the control method of the smart accordion of the technical solution of the present application, by providing five scale keys on the smart accordion corresponding to the five fingers of the human body, and configuring the scale keys to emit corresponding scale sounds when triggered, allows the user to play music with one hand through the smart accordion. The advantage of single-handed playability further facilitates the miniaturization of the smart accordion. It can be seen that compared to traditional key instruments, the control method of the smart accordion of the present application, while meeting the convenience of music performance, helps to achieve the miniaturization of the smart accordion, thereby improving the portability of the smart accordion.

[0120] In one embodiment, the control method of the intelligent accordion further includes:

[0121] In the practice mode, if a preset practice instruction based on the scale key is received from the user, the corresponding practice task is executed.

[0122] Among them, practice mode refers to a mode for users to practice scales, fingering, and repertoire, etc.; and practice tasks refer to performance tasks that users need to complete in practice mode. By setting practice tasks, it helps to improve the purposefulness of practice and helps to improve the user's practice effect.

[0123] Specifically, after starting the smart accordion, if the user wants to practice scales, fingerings, or music, they can enter practice mode by pressing the corresponding function selection button on the smart accordion, or control the smart accordion to enter practice mode through the app on the smart terminal. After entering practice mode, the user can press the scale button to enter the preset practice command and then perform the corresponding training.

[0124] It can be understood that binding the preset practice instructions with the scale keys is beneficial to reducing the number of keys on the smart accordion, which can further facilitate the miniaturization design of the smart accordion and improve the portability of the smart accordion.

[0125] like Figure 7 As shown, in one embodiment, in the practice mode, when a preset practice instruction based on the scale key is received from the user, a corresponding practice task is executed, including:

[0126] S110 : When a first preset practice instruction inputted by the user based on a first scale key is received, a preset scale practice table is obtained and played.

[0127] Among them, the first scale key refers to any one of the five scale keys, which can be pre-set when the smart accordion leaves the factory, or can be adaptively set by the user according to his or her own usage habits. Exemplarily, the first scale key can be an index finger key.

[0128] Specifically, in practice mode, if the first preset practice instruction is received, it can be considered that the user needs to practice scales (i.e., practice the fingering required for each scale). At this time, a preset scale practice table can be obtained (see Table 1 for details).

[0129] S120: Play the scales in the preset scale practice table based on a preset play order, wherein, during the scale playing process, if a key signal corresponding to the current scale is received, play the next scale.

[0130] The preset play order may be a play order from bass octave to treble octave (i.e., from bass to treble octave). to high notes You can also play the middle notes 1234567 (do, re, mi, fa, so, la, si) first, and then play the bass notes or high pitch

[0131] Among them, during the process of playing the scale, if a key signal corresponding to the current scale is received, the next scale will be played. This means that after the current scale is played, the next scale will only be played when the user presses the scale key or scale key combination corresponding to the current scale (that is, the user presses the key correctly).

[0132] It can be understood that in practice mode, the user can enter the scale practice mode by triggering the first scale button. In scale practice mode, the user needs to complete the fingering practice tasks of the scales in each octave to improve the user's proficiency in using the smart piano.

[0133] In one embodiment, the intelligent accordion further comprises five key indicator lights (not shown) corresponding one to one with the five scale keys. The five key indicator lights are used to indicate the positions of the five scale keys.

[0134] In the practice mode, if a preset practice instruction based on the scale key is received from the user, the corresponding practice task is executed, which also includes:

[0135] When the current scale is played, the button indicator light corresponding to the current scale is controlled to light up.

[0136] For example, please refer to Table 1. If the current scale is "1 (do)" for middle pitch, the indicator light of the key corresponding to the index finger key will light up; if the current scale is " (re)”, the two button indicator lights corresponding to the middle finger button and the little finger button are controlled to light up at the same time. For the lighting methods of other button indicator lights, please refer to the above examples and will not be explained here one by one.

[0137] Specifically, when playing a scale in practice mode, the indicator light of the button corresponding to the current scale is controlled to light up. In this way, the user can be intuitively prompted to the scale button corresponding to the current scale, thereby reducing the user's learning cost and improving the user's learning results.

[0138] It is worth noting that the button indicator light can be in a constant light mode or a flashing mode. When the button indicator light is in a constant light mode, the button indicator light will go out after the user correctly triggers the scale button corresponding to the current scale.

[0139] like Figure 8As shown, in an embodiment, in the practice mode, if a preset practice instruction entered by the user based on the scale keys is received, a corresponding practice task is performed, including:

[0140] S210, when a second preset practice instruction entered by the user based on a second scale key is received, the five key indicator lights are controlled to turn on and off based on a preset practice rhythm.

[0141] Specifically, in the practice mode, if the user triggers the second scale key (at this time, the processor of the smart ukulele will receive the second preset practice instruction), it can be considered that the user wants to practice rhythm, so the preset practice rhythm can be obtained, and the key indicator lights turn on and off (i.e. the key indicator lights flash) with the preset practice rhythm. Optionally, the preset practice rhythm includes the on-off sequence and the on-off duration of the key indicator lights.

[0142] Specifically, in the practice mode, if the user triggers the second scale key (at this time, the processor of the smart ukulele will receive the second preset practice instruction), it can be considered that the user wants to practice rhythm, so the preset practice rhythm can be obtained, and the key indicator lights turn on and off (i.e. the key indicator lights flash) with the preset practice rhythm. Optionally, the preset practice rhythm includes the on-off sequence and the on-off duration of the key indicator lights.

[0143] S220, based on the key signal entered by the user following the key indicator lights, a user practice rhythm is generated.

[0144] Specifically, in the rhythm practice mode, after the key indicator lights of the smart ukulele turn on and off based on the preset practice rhythm, the user needs to trigger different scale keys or combinations of scale keys following the lit key indicator lights, at this time, the smart ukulele can receive the key signal generated when the user triggers different scale keys (i.e. the key signal entered by the user), and generate a user practice rhythm based on these key signals.

[0145] S230, output a first practice score based on the matching degree of the user practice rhythm and the preset practice rhythm.

[0146] The matching degree includes the consistency of the user practice rhythm and the preset practice rhythm in terms of scale and rhythm, and the consistency of rhythm is mainly reflected by the duration of each scale.

[0147] Specifically, after the preset practice rhythm is completed, the processor of the smart ukulele can output a first practice score based on the matching degree of the user practice rhythm and the preset practice rhythm to show the user's practice result.

[0148] It can be understood that in the practice mode, the user can enter the rhythm practice mode by triggering the second scale key, and in the rhythm practice mode, the user needs to complete various rhythm practice tasks to improve the user's proficiency in using the smart ukulele.

[0149] like Figure 9 As shown, in one embodiment, in the practice mode, when a preset practice instruction based on the scale key is received from the user, a corresponding practice task is executed, including:

[0150] S310: When receiving a third preset practice instruction input by the user based on the third scale key, play the preset practice track.

[0151] Among them, the third scale key can be any one of the five scale keys. Optionally, in order to facilitate the user to enter different practice modes, the third scale key is any scale key different from the first scale key and the second scale key. Exemplarily, the third scale key can be a ring finger key.

[0152] Specifically, in practice mode, if the user triggers the third scale button (at this time the processor of the smart accordion will receive the third preset practice instruction), it can be considered that the user wants to practice the song, and then the preset practice song can be obtained and the speaker can be controlled to play the preset practice song.

[0153] S320: Obtain a performance piece performed by the user based on the preset practice piece.

[0154] Specifically, in the music practice mode, the smart accordion plays a preset music piece. When playing the preset music piece, the smart accordion button indicator lights up and turns off in conjunction with the scale in the preset music piece to prompt the user. When playing the preset music piece, the user needs to type in different scales according to the preset music piece (by triggering the scale button or the scale button combination). According to the scale typed by the user, the processor of the smart accordion can generate the corresponding music piece.

[0155] S330: Output a second practice score based on the matching degree between the performance piece and the preset practice piece.

[0156] The matching degree includes the consistency of scales and rhythms between the performed piece and the preset practice piece. The consistency of rhythms is mainly reflected by the duration of each scale.

[0157] Specifically, after the preset practice piece is played, the processor of the smart accordion can output a second practice score based on the matching degree between the piece played by the user and the preset practice piece, so as to show the user's practice result.

[0158] It can be understood that in practice mode, the user can enter the song practice mode by triggering the third scale button. In song practice mode, the user needs to complete the song practice tasks of the preset practice songs to improve the user's proficiency in using the smart accordion.

[0159] like Figure 10 As shown, in one embodiment, when receiving the third preset practice instruction input by the user based on the third scale key, playing the preset practice track includes:

[0160] S311. After receiving the third preset practice instruction, if a switch instruction inputted by the user based on the third scale key is received, switch the practice track.

[0161] Specifically, after entering the music practice mode, the user can continue to press the third scale button to input a switching instruction. Upon receiving the switching instruction, the smart accordion will switch the practice music from the preset music library. In other words, upon receiving the switching instruction, the smart accordion will switch the practice music from the preset music library. When switching the practice music, the smart accordion's speaker can be controlled to broadcast the name of the current preset practice music to prompt the user.

[0162] S312: After the practice track is switched, if a confirmation instruction based on the user pressing the fourth scale key is received, the current practice track is played as the preset practice track.

[0163] The fourth scale button can be any one of the five scale buttons. Optionally, to facilitate user confirmation, the fourth scale button can be any scale button that is different from the first scale button, the second scale button, and the third scale button. Exemplarily, the fourth scale button can be a thumb button.

[0164] Specifically, after switching the practice track, if the user wants to practice the current track, the thumb button can be triggered to confirm. After confirmation, the intelligent accordion can play the current practice track.

[0165] It is understood that the ability to switch between practice tracks increases the number of tracks a user can practice, which helps to enhance the user's learning interest. In addition, using the same third scale button to enter the track practice mode and switch practice tracks helps reduce the user's learning cost and helps reduce the number of buttons on the smart accordion, thereby facilitating the miniaturization of the smart accordion.

[0166] In one embodiment, the control method of the intelligent accordion further includes:

[0167] When receiving the instrument change instruction based on the fifth scale key pressed by the user, the sound-generating instrument currently simulated by the intelligent accordion is switched.

[0168] Among them, the sound-making instruments that can be simulated by the intelligent harpsichord include but are not limited to the following: piano, violin, cello, saxophone, clarinet, oboe, piccolo, flute, trumpet, French horn, trombone, tuba, guitar, bass, guzheng, pipa, erhu, and drum set.

[0169] Specifically, after the smart accordion is started, the user can trigger the fifth scale button to switch instruments. The fifth scale button can be any scale button. Exemplarily, the fifth scale button can be a thumb button. When switching instruments, the speaker of the smart accordion can be controlled to broadcast the name of the current instrument to prompt the user.

[0170] It can be understood that switching between musical instruments helps to increase the number of different musical instrument sounds produced by the smart accordion to meet the different usage needs of users.

[0171] In addition, the present invention also provides a computer-readable storage medium. The computer-readable storage medium can be any one of a hard disk, a multimedia card, an SD card, a flash memory card, an SMC, a read-only memory (ROM), an erasable programmable read-only memory (EPROM), a compact disc read-only memory (CD-ROM), a USB memory, or any combination thereof. The computer-readable storage medium includes a control program 70 for the intelligent accordion. The specific implementation of the computer-readable storage medium of the present invention is substantially the same as the specific implementation of the intelligent accordion control method and the intelligent accordion 1 described above, and will not be further described here.

[0176] Second embodiment

[0177] See also Figures 11-15 A second embodiment of the present application provides an intelligent accordion 100, which includes a housing 10 having a storage cavity 101; a sound module 11, a plurality of scale keys 12, a control module 13, the sound module 11, and a battery 18 are arranged in the housing 10, the scale keys 12 are used for operation by a user holding the housing 10 with one hand, and the scale keys 12 are used to trigger and generate a first key signal when operated; the control module 13 is located in the storage cavity 101, electrically connected to the sound module 11 and the plurality of scale keys 12, and is used to receive the first key signal and control the sound module 11 to emit corresponding scale tones according to the first key signal; the battery 18 is also electrically connected to the control module 13.

[0178] The smart accordion 100 of this embodiment is provided with multiple scale buttons 12 and a sound module 11. When a user presses the scale buttons 12, they can not only exercise the strength and flexibility of their fingers, but also cause the sound module 11 to emit sounds of various tones. Furthermore, the user can play music on the smart accordion 100 according to the sheet music. This improves the entertainment value of the smart accordion 100, allowing users to exercise their fingers while also having fun, avoiding boring exercises, increasing user usage time, and improving user experience. Furthermore, the scale buttons 12 can be operated by the user while holding the housing 10 with one hand, further improving the convenience and targeted training of the smart accordion 100.

The battery 18 is in the form of a rectangular flat plate, with the surface of the battery 18 parallel to the long axis of the ellipsoid. It is understood that when the housing 10 is cylindrical or prismatic, there will be edges. When a user grasps the housing 10, the portion of the palm that contacts the edges will experience a large interaction force with the edges, which can easily cause fatigue and damage to the palm. However, when the housing 10 is ellipsoidal, the surface of the housing 10 is relatively smooth, which avoids the aforementioned problems and greatly facilitates user use.

[0182] Furthermore, the intelligent accordion 100 also includes a first fixing portion 17 and a second fixing portion 19, the first fixing portion 17 is connected to the inner surface of the connecting portion 104 on the opposite side to the multiple second buttons 122, the second fixing portion 19 is connected to the inner surface of the connecting portion 104 on the opposite side to the multiple second buttons 122, the second fixing portion 19 is located outside the first fixing portion 17, and the second fixing portion 19 is used to enclose a storage space with the connecting portion 104 and the first fixing portion 17, and the battery 18 is arranged in the storage space.

[0188] Furthermore, the smart accordion 100 further includes at least one support member 26 , which is connected to the inner surface of the housing 10 and is used to abut and support at least one of the battery 18 and the control module 13 .

[0189] Third embodiment

[0190] See also Figures 6-22 A third embodiment of the present application provides an intelligent accordion 100, which includes: a housing 10 having a storage cavity 101 and a first key hole 105; a sound module 11 disposed in the housing 10; a plurality of scale keys 12, the scale keys 12 being operable when a user holds the housing 10 with one hand, the scale keys 12 comprising an operation key 120 disposed in the first key hole 105 and a first trigger portion 121, the operation key 120 being configured to trigger the first trigger portion 121 to generate a first key signal when operated, the operation key 120 comprising a light-transmitting area 122a; a control module 13 disposed in the storage cavity 101, the control module 13 being electrically connected to the sound module 11 and the plurality of scale keys 12, for receiving the first key signal and controlling the sound module 11 to emit corresponding scale tones according to the first key signal; and a light-emitting element 20 disposed below the operation key 120, electrically connected to the control module 13, and configured to emit light toward the light-transmitting area 122a.

[0191] In the smart accordion 100 provided in the embodiment of the present application, the light-emitting element 20 emits light toward the light-transmitting area 122a of the operation key, giving the scale keys 12 a lighting effect. This not only enhances the appearance but also illuminates during playing, enhancing the user experience. In particular, the light-emitting element 20 can be controlled in conjunction with the control module 13, so that the light-emitting element 20 can illuminate in advance to guide the user's playing, or illuminate after the user presses the key to provide feedback.

[0192] Furthermore, the operating key 120 includes a cover portion 122 for user operation, a pressing portion 123 connected to the cover portion 122 and used to trigger the first trigger portion 121, and a mounting portion 124 connected to the cover portion 122. The mounting portion 124 is used to connect to the housing 10 to mount the operating key 120 in the first key hole 105. The light-transmitting area 122a is provided on the cover portion 122. It can be understood that the use of a mechanical scale key 12 has advantages such as simple structure, mature technology, and high stability. Furthermore, the light-transmitting area 122a provided on the cover portion 122 also provides better guidance, facilitating user performance guidance.

[0193] Further, the shell 10 comprises a shell body 106 with a first button hole 105, a side plate 107 connected to the edge of the first button hole 105 and extending towards the inside of the receiving cavity 101, and a bottom plate 109 connected to the side plate 107 and having an opening 108, the side plate 107 and the bottom plate 109 surrounding a button slot 105a, the scale button 12 being arranged in the button slot 105a, the pressing part 123 being used to pass through the opening 108 to press the first trigger part 121; the outer surface of the cover plate part 122 is an arc-shaped convex surface, the joint between the cover plate part 122 and the part of the shell body 106 close to the first button hole 105 is smoothly transitioned, and the cover plate part 122 and the shell body 106 jointly form an ellipsoid or a sphere. Through the design of the button slot 105a, the scale button 12 can be stably received and installed, the stability of the overall structure is improved, and the operation key 120 can be installed in the button slot 105a from the first button hole 105, and the assembly is relatively simple. The joint between the cover plate part 122 and the part of the shell body 106 close to the first button hole 105 is smoothly transitioned, the cover plate part 122 and the shell body 106 jointly form an ellipsoid or a sphere, and the smart harmonica 100 also has a smooth outer surface, which is convenient for holding and operating.

[0194] Further, the installation part 124 is located in the button slot 105a and comprises a clamping hook 124a located away from the cover plate part 122, the clamping hook 124a being detachably clamped with the bottom plate 109 or the side plate 107 through the opening 108; the operation key 120 further comprises a side wall part 125 connected to the cover plate part 122, the installation part 124 and the side wall part 125 having a gap therebetween, one end of the side wall part 125 away from the cover plate part 122 abutting against the bottom plate 109, and the side wall part 125 and the installation part 124 contacting the inner surface of the side plate 107 close to the button slot 105a. Through the above structure, the operation key 120 and the shell 10 are detachably connected, which is convenient for assembly, disassembly and maintenance and the like.

[0195] Further, the opening 108 comprises a first part 108a located in the middle and at least two second parts 108b located at the periphery of the first part 108a, the number of the installation parts 124 is at least two, the pressing part 123 passes through the first part 108a, the installation parts 124 correspond to the second parts 108b, and the clamping hook 124a of the installation part 124 clamps with the side plate 107 through the second part 108b. Through the above structure, the operation key 120 can be uniformly stressed and stably installed on the shell 10.

[0196] Furthermore, there are at least two light-emitting elements 20, each of which is disposed around the first trigger portion 121 and below the cover portion 122. Light from the light-emitting elements 20 is directed toward the light-transmitting area 122a via the space between the side panel 107 and the pressing portion 123. Having at least two light-emitting elements 20 can increase light intensity by directly emitting light toward the light-transmitting area 122a through the space between the side panel 107 and the pressing portion 123. This can also reduce light transmission losses and improve light efficiency. The light-emitting elements 20 may be light-emitting diodes.

[0197] In one embodiment, the cover portion 122 has at least two spaced-apart light-transmitting areas 122a, and at least two light-emitting elements 20 emit light toward the at least two light-transmitting areas 122a, respectively. Spacers 121b are provided between the at least two light-transmitting areas 122a, so that the light emission of each light-transmitting area 122a is controlled by separately controlling the at least two light-emitting elements 20. By designing the at least two light-emitting elements 20 and the light-transmitting areas 122a, the light emission of each light-emitting element 20 and each light-transmitting area 122a can be individually controlled, allowing the scale button 12 to have a variety of lighting effects, thereby improving the user experience.

[0198] In a modified embodiment, Figure 23 As shown, the cover portion 122 also includes a light-shielding region 121c located outside the light-transmitting region 122a. The light-shielding region 121c is provided with a light-shielding material layer 121d. The light-shielding material layer 121d has an opening 121e corresponding to the light-transmitting region 122a.
