[0040] To make the above-mentioned purposes, features, and advantages of the present application more clearly understood, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.
[0041] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.
[0042] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.
[0043] The embodiment of the present application provides a control method for piano key indicator lights, wherein the piano is in communication with a control terminal, the piano comprises a plurality of keys and an indicator light group corresponding to each of the keys, the indicator light group comprising at least one indicator light, Figure 1 , Figure 1 This is a flow chart of an embodiment of a method for controlling a piano key indicator light of the present application, wherein the method for controlling a piano key indicator light includes:
[0044] Step S10, receiving an indicator light control instruction sent by the control terminal, wherein the indicator light control instruction is generated by note information on a preset music score;
[0045] In an embodiment of the present application, the control terminal that establishes a communication connection with the piano (with a built-in communication module) can be a smart mobile device, such as a mobile phone, which has an application installed on it for controlling the piano. The application can pre-load the music score that the user wants to learn and generate corresponding indicator light control instructions based on the note information in the music score. The note information includes the order of the notes, each note corresponding to a key on the piano. When a note is played, the first-order indicator light group in the corresponding indicator light control instruction is the indicator light group of the key corresponding to the note.
[0046] Exemplarily, the piano is an electric piano.
[0047] Specifically, the indicator light control instruction includes an instruction to light up the indicator light group corresponding to at least three designated keys on the piano, so that the user can intuitively know the key that needs to be pressed at present and the next two keys that need to be pressed in sequence.
[0048] Step S20, lighting up indicator light groups corresponding to at least three keys on the piano according to the indicator light control instruction, wherein the indicator light groups have at least three different lighting modes, and different lighting modes correspond to different pressing sequences;
[0049] After receiving the indicator light control instruction, the indicator light group corresponding to each key is determined according to the information of the three keys contained in the indicator light control instruction (such as numbers or preset identifiers), and the indicator light group is controlled to light up according to the lighting form of each key in the indicator light control instruction.
[0050] It should be noted that in the embodiment of the present application, different lighting forms are used to distinguish the pressing order of each key. The lighting forms may include different lighting positions, different lighting colors, etc., as long as they can be distinguished, and there is no limitation here.
[0051] For example, the three lighting patterns correspond to the first, second, and third priority keys, respectively. The first priority key is the key that needs to be pressed currently, the second priority key is the key that needs to be pressed after pressing the first priority key, and the third priority key is the key that needs to be pressed after pressing the second priority key. It should be noted that during the performance of a musical score, multiple keys may need to be pressed simultaneously, that is, the number of keys corresponding to the first, second, and third priority keys may be multiple.
[0052] Step S30: When the key corresponding to the lit indicator light group is pressed, the indicator light group corresponding to the key is controlled to be extinguished, and the process returns to step S10: receiving the indicator light control instruction sent by the control terminal, until the indicator light control instruction corresponding to the note information of the music score is executed.
[0053] It should be noted that after lighting up each indicator light group according to the indicator light control instruction, the user presses a piano key according to the instruction of the indicator light group. At this time, the playing progress on the music score advances one note, and the indicator light group of the key immediately goes out. Afterwards, the communication module on the piano end can send a prompt message to the control end, prompting the control end that the current key has been pressed and a new indicator light control instruction needs to be generated. After the control end receives the prompt message, it needs to generate a new indicator light control instruction based on the key that needs to be pressed and the next two keys. That is, every time the user presses a key, the control end generates a new control instruction and sends it to the piano, and so on, until all the notes on the music score have been played.
[0054] For example, the control end initially issues an indicator light control command to illuminate the indicator light groups corresponding to key A, key B, and key C in different patterns, with the pressing order being: key A, key B, key C. After the user presses key A, the indicator light group corresponding to key A turns off. The control end then generates a control command to illuminate the indicator light groups corresponding to key B, key C, and key D in different patterns, with the pressing order being: key B, key C, key D. It should be noted that each of keys A, B, C, and D may include multiple keys.
[0055] An embodiment of the present application provides a method for controlling a key indicator light, which is applied to a piano, wherein the piano is communicatively connected to a control terminal, the piano includes a plurality of keys and an indicator light group corresponding to each of the keys, the indicator light group including at least one indicator light, and the method for controlling the key indicator light includes: receiving an indicator light control instruction sent by the control terminal, wherein the indicator light control instruction is generated by note information on a preset music score, and then lighting up the indicator light groups corresponding to at least three keys on the piano according to the indicator light control instruction, wherein the indicator light groups have at least three different lighting forms, and different lighting forms correspond to different pressing sequences, and when the key corresponding to the lit indicator light group is pressed, the indicator light group corresponding to the key is controlled to go out, and the execution step is returned to: receiving the indicator light control instruction sent by the control terminal until the indicator light control instruction corresponding to the note information of the music score is executed. In the technical solution of the embodiment of the present application, the piano can continuously receive the indicator light control instructions sent by the control end, and control the indicator light group of the keys according to the indicator light control instructions, so as to indicate the order in which the learner presses the keys by lighting the indicator lights. In this way, the learner does not need to read the music score, but can intuitively know the keys to be pressed by the lighting of the indicator lights, which effectively reduces the difficulty of getting started with the piano. Moreover, in the embodiment of the present application, three different lighting forms of the indicator light group are used to represent different pressing sequences, so that when the learner presses the keys according to the indicator lights, he can not only know the current key to be pressed, but also know in advance the next two keys to be pressed, which facilitates the smooth pressing of the keys corresponding to the music score, improves learning efficiency, and helps beginners master the piano playing skills of the music score more quickly.
[0056] Furthermore, in a feasible embodiment, the indicator light group includes indicator lights at three different positions, and the lighting form of the indicator light group includes lighting the indicator lights at three different positions individually.
[0057] In the embodiment of the present application, the indicator light group may include indicator lights at three different positions, and different indicator light groups that are lit at the same time can be distinguished by lighting the indicator lights at different positions in the indicator light group.
[0058] The arrangement of the indicator lights in the indicator light group can be set according to the actual situation of the piano, either from top to bottom or from left to right.
[0059] Furthermore, the positions of the indicator lights in the indicator light group include at least a first position, a second position and a third position. When at least one indicator light corresponding to the first position is in a lit state, the pressing order of the keys corresponding to the indicator light group is first priority; when at least one indicator light corresponding to the second position is in a lit state, the pressing order of the keys corresponding to the indicator light group is second priority; when at least one indicator light corresponding to the third position is in a lit state, the pressing order of the keys corresponding to the indicator light group is third priority.
[0060] For example, a single indicator light group is, from left to right, indicator light number 1 (corresponding to the first position), indicator light number 2 (corresponding to the second position), and indicator light number 3 (corresponding to the third position). When only indicator light number 1 is lit, it indicates that the key pressing sequence corresponding to the indicator light group is first priority; when only indicator light number 2 is lit, it indicates that the key pressing sequence corresponding to the indicator light group is second priority; when only indicator light number 3 is lit, it indicates that the key pressing sequence corresponding to the indicator light group is third priority. Because multiple keys may be pressed in the same order, multiple indicator lights in the first position (or second position, or third position) can be lit at the same time.
[0061] In another feasible embodiment, the indicator light group includes one indicator light, and the lighting mode of the indicator light group includes at least three different lighting colors.
[0062] In an embodiment of the present application, the indicator light group may include only one indicator light, which, when illuminated, can display one of three different colors, such as red, yellow, green, or blue, according to the control command received. Compared to a light group consisting of three indicator lights, fewer indicator lights are consumed, and the indicator light group occupies less area, but the indicator light needs to be able to illuminate in multiple colors. In actual applications, manufacturers can choose to use three single-color indicator lights or one indicator light that can illuminate in three colors to form an indicator light group, depending on the cost of the indicator lights.
[0063] Furthermore, the lighting colors of the indicator lights in the indicator light group include at least a first color (such as red), a second color (such as yellow) and a third color (such as blue). When the indicator light group lights up the first color, the pressing order of the keys corresponding to the indicator light group is the first priority; when the indicator light group lights up the second color, the pressing order of the keys corresponding to the indicator light group is the second priority; when the indicator light group lights up the third color, the pressing order of the keys corresponding to the indicator light group is the third priority.
[0064] The embodiment of the present application also provides another method for controlling a key indicator light applied to a control terminal, wherein the control terminal is connected to a piano for communication, the piano comprising a plurality of keys and an indicator light group corresponding to each of the keys, the indicator light group comprising at least one indicator light, Figure 2 , the control method of the key indicator light includes:
[0065] Step A10: Generate indicator light control instructions based on the preset note information on the musical score, wherein the indicator light control instructions are used to control the lighting of the indicator lights of the piano keys corresponding to the note information. The indicator light group has at least three different lighting modes, and the different lighting modes correspond to different pressing sequences.
[0066] The control terminal may be a mobile communication device, such as a mobile phone, with a corresponding control application installed on the mobile phone. The application can download or import a musical score as needed and generate corresponding indicator light control instructions based on the note information on the score. It is understood that the indicator light control instructions are used to determine the piano keys corresponding to at least three notes based on the note information recorded on the score, and then control the indicator light groups corresponding to each key to illuminate in different patterns, allowing the user to distinguish the order in which the keys were pressed based on the different lighting patterns.
[0067] Step A20, sending the indicator light control instruction to the piano, so that the piano lights up the indicator light groups corresponding to at least three keys on the piano according to the indicator light control instruction;
[0068] After the indicator light control command is generated, it is sent to the piano, which then illuminates the indicator light groups corresponding to at least three keys on the piano in different lighting patterns according to the indicator light control command. It should be noted that the process of lighting the indicator light groups according to the indicator light control command can refer to the aforementioned steps S20 to S30, and the number of indicator lights in the indicator light group or the lighting colors of the indicator lights are also consistent with the aforementioned method for controlling the key indicator lights applied to the piano, and will not be further described here.
[0069] In step A30, when the key corresponding to the lit indicator light group is pressed, the process returns to step A10, generates an indicator light control instruction based on the preset note information on the music score, and sends it to the piano until the indicator light control instruction corresponding to the note information on the music score is executed.
[0070] When a key corresponding to a lit indicator light group on the piano is pressed, the note on the score advances one, and the indicator light group for that key immediately turns off. The piano's communication module then sends a prompt to the control terminal, notifying it that the current key has been pressed and that a new indicator light control instruction needs to be generated. The control terminal then returns to step A10. In other words, each time the user presses a key, the control terminal generates a new control instruction and sends it to the piano, and so on, until all notes on the score have been played.
[0071] For example, the control end initially issues an indicator light control command to illuminate the indicator light groups corresponding to key A, key B, and key C in different patterns, with the pressing order being: key A, key B, key C. After the user presses key A, the indicator light group corresponding to key A turns off. The control end then generates a control command to illuminate the indicator light groups corresponding to key B, key C, and key D in different patterns, with the pressing order being: key B, key C, key D. It should be noted that each of keys A, B, C, and D may include multiple keys.
[0072] Furthermore, in a feasible embodiment, the step of generating an indicator light control instruction according to preset note information on the music score may include:
[0073] Step A11, obtaining the first three notes in the note information and determining the keys corresponding to the first three notes, wherein the first three notes refer to the first three notes from the first note in the music score, or the first three notes from the note corresponding to the second key in the previous indicator light control instruction;
[0074] Step A12: Generate indicator light control instructions corresponding to the keys corresponding to the first three notes, wherein the indicator light control instructions are used to control the lighting of the indicator light groups corresponding to the keys corresponding to the first three notes, and the lighting forms of the indicator light groups are different.
[0075] For example, when the control end first generates the indicator light control instruction, it takes the first note of the music score as the starting point, determines the keys corresponding to the first three notes, and generates indicator light control instructions for controlling the indicator light groups corresponding to the three keys to light up in different forms according to the order of the three notes.
[0076] For example, when the control end generates an indicator light control instruction for a non-initial time, the note corresponding to the second-ranked key in the last generated indicator light control instruction is used as the starting point, the keys corresponding to the first three notes starting from the note are determined, and indicator light control instructions are generated in the order of the three notes to control the indicator light groups corresponding to the three keys to light up in different ways. This is because after the indicator light control instruction sent last time is executed by the piano and the user presses the first-ranked key, the key corresponding to the second-ranked key in the last sent indicator light control instruction becomes the first-ranked key in this pressing sequence, so this key needs to be used as the starting point, and the key corresponding to the third-ranked key in the last sent indicator light control instruction becomes the second-ranked key in the indicator light control instruction generated this time. Finally, the third-ranked key in the indicator light control instruction generated this time needs to be postponed by one based on the note that has been determined as the second-ranked key in the music score to determine the next note and the third-ranked key corresponding to the note.
[0077] The control method for the key indicator lights applied to the control terminal provided in the embodiment of the present application adopts the control method for the key indicator lights in the above embodiment, which can solve the technical problem that it is currently difficult to learn piano. Compared with the existing technology, the beneficial effects of the control method for the key indicator lights applied to the control terminal provided in the embodiment of the present application are the same as the beneficial effects of the control method for the key indicator lights applied to the control terminal provided in the above embodiment, and the other technical features of the control method for the key indicator lights are the same as the features disclosed in the above embodiment, and are not further described here.
[0078] It should be noted that this example is only used to assist in understanding the present application and does not constitute a limitation on the control method of the piano key indicator light of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
[0079] The present application also provides a control device for a piano key indicator light, which is applied to a piano. Figure 3 , the control device of the key indicator light includes:
[0080] The instruction receiving module 11 is used to receive the indicator light control instruction sent by the control terminal, wherein the indicator light control instruction is generated by the note information on the preset music score;
[0081] A light group lighting module 12 is used to light up the light groups corresponding to at least three keys on the piano according to the indicator light control instruction, wherein the indicator light group has at least three different lighting modes, and different lighting modes correspond to different pressing sequences;
[0082] The light group extinguishing module 13 is used to control the light group corresponding to the lighted indicator light group to extinguish when the key corresponding to the key is pressed, and return to the execution step: receiving the light control instruction sent by the control end until the light control instruction corresponding to the note information of the music score is executed.
[0083] In one embodiment, the indicator light group includes indicator lights at three different positions, and the lighting form of the indicator light group includes lighting the indicator lights at three different positions individually.
[0084] In one embodiment, the positions of the indicator lights in the indicator light group include at least a first position, a second position and a third position. When at least one indicator light corresponding to the first position is in a lit state, the pressing order of the keys corresponding to the indicator light group is the first priority; when at least one indicator light corresponding to the second position is in a lit state, the pressing order of the keys corresponding to the indicator light group is the second priority; when at least one indicator light corresponding to the third position is in a lit state, the pressing order of the keys corresponding to the indicator light group is the third priority.
[0085] In one embodiment, the indicator light group includes one indicator light, and the lighting modes of the indicator light group include at least three different lighting colors.
[0086] In one embodiment, the lighting colors of the indicator lights in the indicator light group include at least a first color, a second color and a third color. When the indicator light group lights up the first color, the pressing order of the keys corresponding to the indicator light group is the first priority; when the indicator light group lights up the second color, the pressing order of the keys corresponding to the indicator light group is the second priority; when the indicator light group lights up the third color, the pressing order of the keys corresponding to the indicator light group is the third priority.
