[0053] Hereinafter, with reference to FIGS. 1 to 17, a color recognition-based music playback device according to some embodiments of the present invention will be described in detail.

[0054]

[0055] FIG. 1 is a drawing for explaining a color recognition-based music player according to some embodiment of the present invention. FIG. 2 is a side view of the music player of FIG. 1. FIG. 3 is a drawing for explaining a turntable of the music player of FIG. 1. FIG. 4 is a drawing for explaining a turntable hole of the turntable of FIG. 3.

[0056]

[0057] Referring to FIGS. 1 to 4, the music playback device (1) may include a main body (mb), a turntable, a tempo control module (tc), a drawing paper (p), a barcode sensor (bs), an instrument control module (ic), a display module (in), and an index recognition bar (b).

[0058] For example, the main body (mb) may include a fixing hole (mdh) formed at the top and a joint (j) formed spaced apart from the fixing hole (mdh). The fixing hole (mdh) may be coupled with a turntable. The fixing hole (mdh) will be described later in conjunction with the description of the turntable. The joint (j) may be coupled with an index recognition bar (b). The joint (j) will be described later in conjunction with FIG. 5.

[0059] Additionally, the main body (mb) may include a motor and a speaker disposed inside. For example, the motor may provide power to a turntable coupled to a fixed hole (mdh) of the main body (mb) to rotate the turntable. The speaker may output a frequency corresponding to the sound played by the music player (1).

[0060] The turntable may include a rotating plate (t) and a rotating shaft portion (ta). For example, the rotating plate (t) may have a turntable hole (tth) formed in the center and may be positioned on the top of the main body (mb). The center of the turntable hole (tth) and the center of the fixing hole (mdh) may coincide. However, this description is merely illustrative and the embodiments of the present invention are not limited thereto.

[0061] Referring to FIG. 4, the turntable hole (tth) may be formed symmetrically with respect to the first centerline (tl). For example, the turntable hole (tth) may include a first turntable hole (tth1) and a second turntable hole (tth2). The outer surface of the first turntable hole (tth1) may be formed in a circular shape. The second turntable hole (tth2) may be formed such that a part of the outer surface of the first turntable hole (tth1) protrudes outward from the center of the turntable toward the outer surface of the turntable. The outer surface of the first turntable hole (tth1) and the outer surface of the second turntable hole (tth2) may come into contact by forming a groove (tthg).

[0062] The rotating shaft portion (ta) can pass through the fixed hole (mdh) and the turntable hole (tth). Additionally, the rotating shaft portion (ta) can rotate by engaging with the turntable hole (tth) based on power provided by a motor placed inside the main body (mb). The turntable can rotate at the top of the main body (mb) by engaging with the rotating shaft portion (ta) based on power provided by the motor. To this end, the outer shape of the rotating shaft portion (ta) can be formed to the shape of the inner circumferential surface of the turntable hole (tth).

[0063] The tempo control module (tc) can be positioned on the top of the main body (mb) as a button or dial-type interface. For example, the tempo control module (tc) can control the rotational speed of the turntable based on a first tempo set by the user using the tempo control module (tc). A motor positioned inside the main body (bm) can control the power provided to the rotation shaft (ta) so that the rotational speed of the turntable corresponds to the first tempo.

[0064] The drawing paper (p) may include a paper fixing hole (ph) formed in the center. For example, the paper fixing hole (ph) may be formed in the shape of the outer surface of one side of the rotation shaft (ta). By combining the paper fixing hole (ph) and one side of the rotation shaft (ta), the drawing paper (p) can be placed on the top of the turntable. At this time, when the drawing paper (p) is placed on the top of the turntable, a part of the top of the main body (mb) (s) may be formed to protrude in correspondence with the outer shape of the drawing paper (p). Through this, the drawing paper (p) can be placed on the top of the turntable and rotate stably.

[0065] Additionally, the drawing paper (p) may include a paper material, but this is merely illustrative and the embodiments of the present invention are not limited thereto. The drawing paper (p) may be composed of other materials that allow the user to draw colors on the drawing paper (p). The drawing paper (p) may be formed as a material to which colors can be added by the user, with a paper fixing hole (ph) formed in the center and coupled to a rotation axis (ta) to form a shape that can rotate around the rotation axis (ta).

[0066] One side of the drawing paper (p) may include either a side with a pre-drawn image or a side without an image. For example, one side of the drawing paper (p) may have a design corresponding to one of the pre-stored songs drawn on it. In this case, the user may add additional color to the design drawn on one side of the drawing paper (p).

[0067] Additionally, one side of the drawing paper (p) may have guideline lines indicating a time signature. For example, one side of the drawing paper (p) may have lines separating areas evenly divided around the paper fixing hole (ph). When the drawing paper (p) corresponds to a first time signature, one side of the drawing paper (p) may have multiple areas evenly divided around the paper fixing hole (ph) based on the number of notes and unit notes of the first time signature. The user can compose by adding colors to the areas corresponding to each beat based on the guideline lines.

[0068] Additionally, on one side of the drawing paper (p), lines may be drawn to separate multiple areas based on multiple time signatures. For example, a first area on one side of the drawing paper (p) may be drawn to separate multiple areas equally based on the number of notes and unit notes of the first time signature, and a second area on one side of the drawing paper (p) may be drawn to separate multiple areas equally based on the number of notes and unit notes of a second time signature different from the first time signature. That is, the user may compose music with a changing time signature by drawing colors on the drawing paper (p) that is divided into multiple areas based on different time signatures. However, this description is merely illustrative and the embodiments of the present invention are not limited thereto.

[0069] If one side of the drawing paper (p) does not have a picture drawn on it in advance, the user can draw a picture by adding color to one side of the drawing paper (p). Through this, the music player (1) can play a sound corresponding to the picture drawn by the user. The drawing paper (p) will be described later with reference to FIGS. 6 and FIGS. 7.

[0070] The barcode sensor (bs) may be positioned at the top of the main body, spaced apart from the turntable. The barcode sensor (bs) can recognize a barcode by examining the other side of an adjacent drawing paper. The barcode sensor (bs) will be described later together with the barcode of the drawing paper (p) with reference to FIG. 7.

[0071] The instrument control module (IC) may be positioned on the top of the main body (mb) as an interface in the form of a button or a dial. The instrument control module (IC) may provide the user with a plurality of pre-stored instrument types. For example, the instrument control module (IC) may set one of the pre-stored plurality of instrument types as the first instrument by controlling the user's button or dial. The user may set one of the pre-stored plurality of instrument types as the first instrument. The music playback device (1) may output a tone corresponding to the first instrument using the speaker of the main body (mb).

[0072] The display module (in) may be positioned on the top of the main body (mb) spaced apart from the instrument control module (ic). The display module (in) may output user setting information corresponding to at least one of the first instrument and the first tempo. For example, the user setting information may include instrument data, tempo data, and volume data. The first instrument may be instrument data, which is the type of instrument set by the user controlling the instrument control module (ic). The first tempo may be tempo data, which is the music playback speed of the music playback device (1), set by the user controlling the tempo control module (tc). That is, the first tempo may correspond to the rotation speed of the turntable and the speed of recognizing one side of the picture paper (p) of the index recognition bar (b). The volume data may be the volume of the speaker of the main body (mb), which is set by the user controlling the volume control module (vc). However, this description is merely illustrative and the embodiments of the present invention are not limited thereto.

[0073] The display module (in) may display error data of the music player (1). The error data may include turntable error data and index recognition bar error data of the music player (1). The error data may be generated when a problem occurs in the operation of a component of the music player (1). However, this description is merely illustrative and the embodiments of the present invention are not limited thereto.

[0074] Figure 5 is a diagram illustrating the index bar of Figure 1.

[0075] Referring to FIG. 5, the index bar (b) is combined with the joint (j) and can be formed to extend in a first direction in which a turntable is placed at the joint (j). At this time, the drawing paper (p) can be placed between the turntable and the index bar (b).

[0076] Additionally, the distance between the index bar (b) and the turntable can be controlled by the combination of the index bar (b) and the joint (j). For example, the index bar (b) can be separated from the turntable by pressure applied by the user to the top (b1) of the index bar (b). Conversely, the index bar (b) separated from the turntable can be moved in the direction in which the turntable is positioned by pressure applied to the top. Through this, the distance between the index bar (b) and the turntable can be reduced.

[0077] The user can apply pressure to the top of the index recognition bar (b) to separate the index recognition bar (b) from the turntable, and place a drawing paper (p) on the top of the turntable using the space between the index recognition bar (b) and the turntable. In this way, the drawing paper (p) can be placed between the turntable and the index recognition bar (b). However, this description is merely illustrative and the embodiments of the present invention are not limited thereto.

[0078] Additionally, the bottom of the color recognition bar (b) may include a plurality of color sensors (rgbs). The plurality of color sensors (rgbs) may be arranged along the second center line (bl) of the color recognition bar (b). The plurality of color sensors (rgbs) can identify the color of one side of the picture paper (p) adjacent to the bottom of the color recognition bar (b). The speaker can play a sound corresponding to the color recognized by the plurality of color sensors (rgbs).

[0079] Multiple color sensors (RGBs) may be arranged adjacent to multiple light source units (LEDs) that emit light. For example, a first color sensor (RGBSN1) may be arranged between a first light source unit (LED1) and a second light source unit (LED2). Additionally, a second color sensor (RGBSN2) may be arranged between a second light source unit (LED2) and a third light source unit (LED3). An nth color sensor (RGBSNN) may be arranged between an nth light source unit (LEDN) and an n+1th light source unit (LEDN+1).

[0080] Hereinafter, a plurality of color sensors (rgbs) that recognize the color of one side of the drawing paper (p) are described with reference to FIG. 6. For convenience of explanation, the second color sensor (rgbsn2) positioned on the other side of the color recognition bar (b) adjacent to the rotation axis part (ta) is described as the first color sensor (rgbsn2). In addition, the nth color sensor (rgbsnn) positioned on one side of the color recognition bar (b) adjacent to the joint part (j) is described as the second color sensor (rgbsnn).

[0081]

[0082] Figure 6 is a drawing to explain a drawing paper combined with the turntable of Figure 1.

[0083] Referring to FIG. 6, one side of the drawing paper (p) may include a plurality of paper regions distributed around the center of the drawing paper (p).

[0084] A paper fixing hole (ph) may be formed in the center of the drawing paper (p). The paper fixing hole (ph) may be formed in a shape that engages with the rotation axis portion (ta). Fig. 6 <d12>Referring to the, the paper fixing hole (ph) may be formed symmetrically with respect to the third centerline (pl). For example, the paper fixing hole (ph) may include a first paper fixing hole (ph1) and a second paper fixing hole (ph2). The outer surface of the first paper fixing hole (ph1) may be formed in a circular shape. The second paper fixing hole (ph2) may be formed such that a part of the outer surface of the first paper fixing hole (ph1) protrudes outward from the center of the paper fixing hole (ph) toward the outer surface of the drawing paper (p). The outer surface of the first paper fixing hole (ph1) and the outer surface of the second paper fixing hole (ph2) may come into contact by forming a groove (phg).

[0085] Multiple paper regions may be regions distributed at regular intervals centered around the paper fixing hole (ph). For convenience of explanation, some of the paper regions adjacent to the center of the drawing paper (p) are defined as the first paper region (pd1). Some of the paper regions adjacent to the outer surface of the drawing paper (p) are defined as the second paper region (pd2).

[0086] The distance between the center of the first paper area (pd1) and the paper fixing hole (ph) may be the first distance (d1). For example, the distance between the first reference line (sd1) passing through the center of the paper fixing hole (ph) and intersecting the third center line (pl), and the second reference line (sd2) of the first paper area (pd1) may be the first distance (d1).

[0087] The separation distance between the third reference line (sd3) and the first reference line (sd1) of the second paper area (pd2) may be the second separation distance (d2). The first separation distance (d1) may be shorter than the second separation distance (d2). In addition, the area of ​​the first paper area (pd1) may be narrower than the area of ​​the second paper area (pd2).

[0088] Additionally, the first paper area (pd1) may be a first irradiation area that a first light source unit corresponding to the first color sensor (rgbsn2) irradiates onto the drawing paper (p). The first light source unit may be at least one light source unit (LED) positioned adjacent to the first color sensor (rgbsn2). By the first light source unit irradiating the first irradiation area of ​​the drawing paper (p), the first color sensor (rgbsn2) can recognize the first color of the first paper area (pd1). The first color may be at least one color shown in the first paper area (pd1).

[0089] The second paper area (pd2) may be a second irradiation area that a second light source unit corresponding to the second color sensor (rgbsnn) irradiates onto the drawing paper (p). The second light source unit may be at least one light source unit (LED) positioned adjacent to the second color sensor (rgbsnn). By the second light source unit irradiating the second irradiation area of ​​the drawing paper (p), the second color sensor (rgbsnn) can recognize the second color of the second paper area (pd2). The second color may be at least one color shown in the second paper area (pd2).

[0090] The first irradiation area of ​​the first light source unit may be formed narrower than the second irradiation area of ​​the second light source unit to correspond to the width of the first paper area (pd1). However, this description is merely illustrative and the embodiments of the present invention are not limited thereto.

[0091] Next, referring to Fig. 7, the other side of the drawing paper (p) is described.

[0092]

[0093] Figure 7 is a drawing to explain the barcode of the drawing paper of Figure 6.

[0094] Referring to FIGS. 3 and 7, the other side of the drawing paper (p) may further include a barcode (bc). For example, the barcode (bc) may be placed at a location where a barcode sensor (bs) can identify it when the drawing paper (p) is placed on the rotating plate (t) of a turntable and rotated. That is, when the drawing paper (p) is placed on the rotating plate (t) of a turntable, the barcode (bc) may be placed in a portion of the other side of the drawing paper (p) that does not come into contact with or overlap with the rotating plate (t). A portion of the other side of the drawing paper (p) that does not come into contact with or overlap with the rotating plate (t) is defined as the barcode-possible area of ​​the drawing paper (p).

[0095] The barcode-capable area may include a plurality of equally divided areas (p1 to pn). In this case, the barcode (bc) may be placed in a preset area among the barcode-capable areas. For example, the barcode (bc) may be shown in the first barcode-capable area (p1), the second barcode-capable area (p2), the third barcode-capable area (p3), and the fourth barcode-capable area (p4).

[0096] The preset area can be preset based on the time from when the turntable starts rotating until when the barcode sensor (bs) starts recognizing the barcode (bc). The preset area will be described later with reference to FIG. 9.

[0097] Below, the operation of the music player (1) is described with reference to FIGS. 8 and FIGS. 9.

[0098]

[0099] FIG. 8 is a drawing for explaining the operation of the music player of FIG. 1 combined with the drawing paper of FIG. 6. FIG. 9 is a drawing for explaining the change in the position of the paper fixing hole according to the operation of the music player of FIG. 8.

[0100] Referring to FIG. 8, the music player (1) can receive power by the action of pressing the user's power button (pw). The light source part of the index recognition bar (b) of the music player (1) can emit light with the provided power. For example, the top of the index recognition bar (b) can be displayed in multiple colors by the light emission of at least one light source part of the index recognition bar (b).

[0101] Next, the motor of the main body (mb) can provide power to the rotating shaft (ta) by the action of the user pressing the play button (pc). For example, the turntable can rotate around the rotating shaft (ta) by the power provided by the motor.

[0102] The turntable can be rotated in a preset direction (cw) by power provided by a motor and positioned in a playable position. Referring to FIGS. 2, 4, and 9 together, the playable position may be a position where the turntable is positioned so that the first centerline (tl) of the turntable hole (tth) aligns with the playable reference centerline (sl). Additionally, the playable position may be a position where the third centerline (pl) of the paper fixing hole (ph) aligns with the playable reference centerline (sl). The playable position may also be a position where the first centerline (tl) and the barcode sensor (bs) are aligned in a line.

[0103] In the following, for the convenience of explanation, the operation of rotating when the play button (pc) is pressed while the turntable is positioned at the intersection of the playback reference center line (sl) and the third center line (pl) is described.

[0104] Fig. 9 <e11>Referring together with [the image], the turntable can be positioned so that the third centerline (pl) and the playback reference centerline (sl) intersect. The turntable can rotate in a direction (cw) where the third centerline (pl) aligns with the playback reference centerline (sl) by the action of a user pressing the play button (pc). [The image] of FIG. 9 <e13>By referring to the above, the turntable can be placed in a playable position such that the third centerline (pl) and the playback reference centerline (sl) coincide.

[0105] Fig. 9 <e12>When referring to the above, when the turntable rotates so that the third center line (pl) and the playback reference center line (sl) coincide, the barcode sensor (bs) can recognize the barcode (bc) placed on the other side of the picture paper (p) and recognize the background setting data included in the barcode (bc).

[0106] Background setting data may be data corresponding to at least one of tempo and background music. For example, background setting data may include tempo data for rotating a turntable and background music data played by a speaker. The turntable's rotating plate (t) may rotate at a speed corresponding to the tempo data. The speaker may play background music. The turntable's rotating plate (t) may be positioned in a playable position while background music is being played.

[0107] Additionally, the barcode sensor (bs) can maintain a state of not identifying the barcode (bc) while the turntable rotates so that the third centerline (pl) and the playback reference centerline (sl) coincide, when the other side of the picture paper (p) does not contain the barcode (bc). Accordingly, the turntable can be positioned in a playable position by rotating at a speed corresponding to the tempo set by the tempo control module (tc), or positioned in a playable position by rotating at a pre-stored speed. The pre-stored speed may be the speed of the rotation axis part (ta) that rotates by the action of pressing the user's playback button (pc).

[0108] Hereinafter, with reference to FIGS. 10 to 16, the operation method of a music player is described together with a system block diagram.

[0109]

[0110] FIG. 10 is a system block diagram of the music player of FIG. 1. FIG. 11 is a flowchart for explaining a method of playing music of the music player of FIG. 10. FIG. 12 is a flowchart for explaining step S10 of FIG. 11. FIG. 13 is a flowchart for explaining step S20 of FIG. 11. FIG. 14 is a flowchart for explaining step S21 of FIG. 13.

[0111] Referring to FIG. 10, a music player (1) includes an interface (110), a database (120), a processor (130), and a memory (140). In this case, an instrument control driver (icd), a barcode recognition driver (bsd), a tempo control driver (tcd), a sound output driver (sod), and a shared driver (s1d) are loaded into the memory (140) and can be driven or executed by the processor (130). Each driver may be stored in the form of a computer program in storage included in the music player (1) and used. For example, each driver may be stored in the form of a computer in the database (120) included in the music player (1) and used. However, this description is merely illustrative and the embodiments of the present invention are not limited thereto.

[0112] The interface (110) can perform the function of exchanging data between the music player (1) and the user terminal. The interface (110) can transmit data received from the user terminal to other components within the music player (1). The interface (110) may include various communication modules and can perform data exchange between an external device or a user terminal through a communication network. The data received by the interface (110) will be described later with reference to FIG. 15.

[0113] The database (120) performs the function of storing and managing data received through the interface (110). The database (120) can store multiple modules that are loaded into memory (140) and available in the form of programs.

[0114] For example, the database (120) can store data received through the interface (110). The database (120) can store multiple types of musical instruments and the speed of the rotating shaft (ta) that rotates by the action of the user pressing the play button (pc).

[0115] Additionally, the database (120) may store music that is generated or played by the music player (1) recognizing the color and barcode of the picture paper (p). The music that is generated or played may be generated based on the barcode (bc) recognized by the music player (1) through the barcode sensor (bs) and the color recognized by the color recognition bar (b).

[0116] The processor (130) can execute software to control at least one other component (e.g., a hardware or software component) of the music player (1) and can perform various data processing and operations. For example, the processor (130) can load information, commands, or data received from another component (e.g., an interface (110)) into memory (140), perform operations using the loaded information, commands, or data, and store the resulting data in memory (140) or storage (not shown).

[0117] The memory (140) can store and load various data used in at least one component of the music player (1), e.g., the processor (130). For example, the data may include input data or output data for software and related commands.

[0118] Accordingly, the processor (130) can load and use drivers or instructions related to various operations of a color recognition-based music playback device (1) according to some embodiment of the present invention onto memory (140).

[0119] For example, the processor (130) can set the type of instrument using an instrument control driver (icd) loaded in memory (140). The processor (130) can set one of a first instrument selected by the user using a plurality of provided instrument type instrument control modules (ic) and a second instrument selected by the user using an interface (110) as the type of instrument corresponding to the tone output by the music playback device (1). The processor (130) can finally set the type of instrument based on the time when the first instrument is set and the time when the second instrument is set.

[0120] Additionally, referring to FIG. 11, the processor (130) can recognize a barcode on a drawing paper (p) using a barcode recognition driver (bsd) loaded in memory (140) and rotate a turntable based on background setting data corresponding to the barcode (S10). For example, referring to FIG. 12, the processor (130) can rotate the turntable at a speed stored in advance in the database (120) and recognize a barcode (bc) placed on the other side of the drawing paper (p) (S11).

[0121] Next, the processor (130) can control the power provided by the motor to the turntable based on the tempo of the background setting data included in the recognized barcode (bc) to rotate the turntable at a first speed corresponding to the tempo (S13). The first speed may differ from the speed stored in advance in the database (120), but is merely exemplary and the embodiments of the present invention are not limited thereto.

[0122] Additionally, the processor (130) can play background music of the background setting data using the speaker of the main body (mb) (S15). For example, the processor (130) can play background music before the color recognition bar (b) recognizes the color of the drawing paper (p), but can also play background music from the point when the color recognition bar (b) recognizes the color of the drawing paper (p).

[0123] Referring again to FIGS. 10 and FIGS. 11, the processor (130) can identify the color of one side of the drawing paper (p) using the color recognition bar (b) and play at least one sound corresponding to the identified color using a speaker (S20). For example, referring together to FIG. 13, the processor (130) can identify the color recognized by each color sensor of the color recognition bar (b) (S21).

[0124] Referring together with FIG. 14, the processor (130) can recognize the first color of the first paper area distributed around the center of the drawing paper (p) using the first color sensor of the color recognition bar (b) (S211).

[0125] Additionally, the processor (130) can recognize the second color of the second paper area, which is distributed to the center of the drawing paper (p) and separated from the first paper area, using the second color sensor of the color recognition bar (b) (S213).

[0126] The processor (130) can play each sound corresponding to the recognized first color and second color, respectively, using a sound output driver (sod) (S215). For example, the processor (130) can simultaneously play each sound corresponding to the color recognized by each color sensor of the color recognition bar (b). The processor (130) can update the recognized color based on the first paper area and the second paper area that are updated by the rotational motion of the drawing paper (p) that rotates together with the rotating plate (t). The processor (130) can simultaneously play background music corresponding to the barcode and each sound corresponding to the color recognized by each color sensor using a sound output driver (sod). At this time, the processor (130) can play each sound and background music recognized based on the tempo using a speaker.

[0127] Additionally, the processor (130) can control the rotation speed of the turntable based on a first tempo set by the user using the tempo control module (tc). For example, the processor (130) can control the power of the motor using the tempo control driver (tcd) so that the motor can rotate the turntable based on the first tempo.

[0128] Next, with reference to FIGS. 15 and 16, data exchange between a music player (1) and a user terminal based on an interface (110) is described.

[0129]

[0130] FIG. 15 is a diagram illustrating the interface of an application linked with the music player of FIG. 1. FIG. 16 is a flowchart illustrating the operation of the interface of FIG. 15.

[0131] Referring to FIGS. 15 and 16, the processor (130) can provide data to a user terminal using the interface (110) (S30). For example, the processor (130) can create and provide to the user terminal an interface that includes an instrument type set by an instrument control driver (icd), each note of the scale of the instrument type, and a color corresponding to each note, in conjunction with the interface (110).

[0132] The interface may include an instrument control interface (ini), a keyboard interface (kb), and a shared interface. For example, the instrument control interface (ini) may include an instrument name interface (ii) that displays the name of an instrument type configured using an instrument control driver (icd) and an instrument control module (ic), and an instrument type change interface (ici) that can change the instrument type.

[0133] The processor (130) can update the interface with the first instrument, which is the type of instrument of the music player, via the instrument control interface (ini) (S40). For example, the user can change the type of instrument by pressing a button shown on the instrument type change interface (ici). The instrument name interface (ii) may show the name of the type of instrument that is updated by the instrument type change interface (ici).

[0134] Conversely, the instrument control interface (ini) can be updated based on the type of instrument set by the user using the instrument control module (ic) of the music player device (1).

[0135] Additionally, the keyboard interface (kb) may be an interface that displays each note of a musical scale in the form of a keyboard. For example, the keyboard interface (kb) may include a black key interface (bk) that displays black keys and a white key interface (wk) that displays white keys.

[0136] Each key on the keyboard interface (kb) can be displayed based on sound matching data stored in the database (120). For example, the color of each key on the keyboard interface (kb) can be displayed as a color recognized by the color sensor of the color recognition bar (b).

[0137] The color of each key of the keyboard interface (kb) can be depicted as a color corresponding to the pitch of each key. For example, the middle key (n1) depicted in the white key interface (wk) can be depicted as a color corresponding to middle.

[0138] Additionally, for each key of the keyboard interface (kb), data corresponding to at least one of the musical note and octave for the corresponding note may be displayed together. For example, in the part of the interface where the middle key (n1) is displayed, at least one of "C4" and "Do" may be displayed. The musical note may be displayed in a language stored in a database. However, this description is merely illustrative and the embodiments of the present invention are not limited thereto.

[0139] The shared interface may include at least one interface that shares at least one. For example, the shared interface may include an interface capable of sharing music generated by the music player (1). The music generated by the music player (1) may be stored in a user terminal or provided to an external system through the shared interface.

[0140] The shared interface may include an interface for storing data in a user terminal or providing it to an external system, wherein the music generated by the music player (1) and at least one image are combined. The at least one image may be one side image of the drawing paper (p), an image of the music player (1) on which the drawing paper (p) is placed, or a video of the drawing paper (p) rotating on the music player (1). The at least one image may be an image that is requested by the user and captured through the camera module of the user terminal, or an image and video generated based on the captured image. However, this description is merely illustrative and the embodiments of the present invention are not limited thereto.

[0141] Additionally, the shared interface may include a first shared interface (s1), a second shared interface (s2), and a third shared interface (s3). The first shared interface (s1) may be an interface for sharing music generated by the music player (1).

[0142] The second shared interface (s2) may include an interface connected to an interface of an external system. For example, the second shared interface (s2) may include a company interface related to the music player (1) and an interface for selling music generated by the music player (1).

[0143] The third shared interface (s3) may include a music playback device (1) and an interface that provides a method for using the interface. However, this description is merely illustrative and the embodiments of the present invention are not limited thereto.
