This application claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2020-0058375, filed on May 15, 2020, in the Korean Intellectual Property Office (KIPO), the disclosure of which is incorporated by reference herein in its entirety.
Disclosed herein are a sound source file structure, a recording medium recording the same, and a method of producing a sound source file, and more particularly, a sound source file structure, a recording medium recording the same, and a method of producing a sound source file that enable a sound source output device, outputting lyrics together with melodies, to output lyrics as audible sounds right before melodies corresponding to the lyrics start, to help a user to remind the lyrics based on accompaniment for a song after the accompaniment starts to be provided, and to help the user to sing based on correct lyrics corresponding to the melodies.
A song accompaniment device displays lyrics of a song being played on a display, combines a vocal sound input through a microphone with accompaniment for the song and outputs the combination of the vocal sound and the accompaniment through a speaker. A user selects a desired song through the song accompaniment device, and sings the song based on accompaniment for the song.
The user sings the song based on melodies while seeing lyrics of the song on the display. In this case, the user can sing the song using the song accompaniment device with no need to remember the lyrics. The song accompaniment device can be used in various environments. For example, a set-top box used in homes performs a song accompaniment function. Accordingly, lyrics are displayed on the TV connected with the set-top box, and accompaniment (melody) audio signals are output through a provided speaker. The song accompaniment device, as described above, displays lyrics on the display and helps the user to sing using the lyrics synchronized with the accompaniment.
Referring to
The song accompaniment device 10 receives an audio file of a selected song from the server 20, plays the received audio file, outputs audio signals including melodies through a speaker within a period where a series of parts to be played are played. The song accompaniment device 10 outputs audio signals including a lyric voice corresponding to lyrics of following parts to be played through the speaker during a rest period without melodies in the period where a series of parts to be played are currently being played. That is, the song accompaniment device 10 outputs following lyrics as audio signals at a time when the following lyrics do not overlap melodies, helps the user to easily recognizes the lyrics without memory of the lyrics, and to easily sing a song without disturbing the melody (the melody playing).
The server 20 is provided with (stores) a plurality of audio files, receives a request for transmission of a selected song from the song accompaniment device 10, and transmits an audio file corresponding to the song (e.g., a song corresponding to a song number) subject to the received request for transmission to the song accompaniment device 10 that makes the request for transmission.
In a situation where the song accompaniment system is not provided with a display or a display cannot be used, the user may be unable to sing a song in response to melodies or may sing a song based on incorrect lyrics because the user does not know or remember the lyrics.
For example, when a user sings based on accompaniment for a song under the circumstances where the user cannot see lyrics on the display, e.g., while the user is driving a vehicle, the user may not remember the lyrics.
Further, although a song accompaniment device 10 is installed in a vehicle, there are times when the song accompaniment device 10 cannot access a server 20 while the vehicle is moving. In this case, the song accompaniment device 10 cannot receive an audio file from the server 20 and the song accompaniment device 10 cannot be used.
Against this backdrop, there is a growing need for a technology enabling a song accompaniment device 10 to be used even when a display cannot be used or is not provided, enabling the song accompaniment device 10 to be used without a connection to a server 20, and enabling a user to recognize lyrics of a song easily and intuitively.
Embodiments of the present invention are directed to a sound source file structure, a recording medium recording the same, and a method of producing a sound source file, and more particularly, a sound source file structure, a recording medium recording the same, and a method of producing a sound source file that enable a sound source output device, outputting lyrics together with melodies, to output lyrics as audible sounds right before melodies corresponding to the lyrics start, to help a user to remind the lyrics based on accompaniment for a song after the accompaniment starts to be provided, and to help the user to sing based on correct lyrics corresponding to the melodies.

The above and other features and aspects of the present disclosure of invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
Advantages and features of the present disclosure, and a method for achieving the same can be clearly understood from the following embodiments that are specifically described with reference to the accompanying drawings. However, embodiments of the present disclosure can be implemented in various different forms, and should not be construed as being limited only to the embodiments set forth herein. Rather, the embodiments set forth herein are provided as examples so that the present disclosure can be thorough and complete and can fully convey the subject matter of the disclosure to one having ordinary skill in the art to which the disclosure pertains. The subject matter of the disclosure should be defined only by the scope of the appended claims. Additionally, in some embodiments, detailed description of well-known processes, component structures and technologies are omitted if they are deemed to make the disclosure vague. Throughout the disclosure, like reference numerals denote like components.
In the drawings, thicknesses are exaggerated for clarity in illustrating a plurality of layers and areas. Throughout the disclosure, similar parts are given identical reference numerals. When one part such as a layer, a film, an area, a plate and the like is described as being “on” another part, it can mean that one part is “directly on” another part and that an additional part is interposed between the two parts. When one part is described as being “directly on” another part, it can mean that no additional part is interposed between the two parts. Further, it is to be understood that when one part such as a layer, a film, an area, a plate and the like is described as being “under” another part, it can mean that one part is “directly under” another part and that an additional part is interposed between the two parts. When one part is described as being “directly under” another part, it can mean that no additional part is interposed between the two parts.
Spatial terms such as “below”, “beneath”, “lower”, “above”, “upper” and the like can be used herein to readily describe a relative position between one component and other components or among components. The spatial terms should be interpreted as including different directions in which the components are used and operated as well as the direction in the drawings. For example, when components in the drawings are overturned, one component “below” or “beneath” another component can be placed “above” another component. Accordingly, the term “below” or “beneath” can imply not only an upward direction but also a downward direction. The components can be disposed in different directions. Thus, the spatial terms can be interpreted based on the disposition direction.
When one part is described as being “connected”, “coupled”, or “connected” to another part, one part can be directly connected, coupled or connected to another part. However, it is also to be understood that the two parts can electrically be “connected”, “coupled”, or “connected” with an additional component therebetween. Throughout the disclosure, unless explicitly described to the contrary, when one part is described as comprising another part, it should imply the inclusion of any other component but not the exclusion of any other component.
It will be understood that, although the terms “first,” “second,” “third,” and the like may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Thus, “a first element” discussed below could be termed “a second element” or “a third element,” and “a second element” and “a third element” can be termed likewise without departing from the teachings herein.
Unless otherwise defined, all the terms (technical and science words) used herein have the same meaning as commonly understood by one having ordinary skill in the art. Additionally, terms such as those defined in commonly used dictionaries should not be interpreted in an ideal or overly sense, unless explicitly defined herein.

The recording medium 200, on which the sound source file structure according to an embodiment is recorded, may be a magnetic memory element including a magnetic tunnel junction (MTJ) element, and as illustrated in
As illustrated in
As illustrated in
In such a memory cell array structure, source lines SL 23 that extend in the same direction as that of a bit line BL 25 alternately share memory cells C with the bit line BL 25 adjacent thereto. In particular, when one word line WL 22 is selected, since there is no memory cell C around a selected memory cell C, it is possible to prevent a memory cell C from being repeatedly selected. That is, in the memory cell array structure according to the present embodiment, there is no memory cell C immediately adjacent to one memory cell C along one word line WL 22 and a memory cell C immediately adjacent to the one memory cell C may be arranged in another word line WL 22 adjacent to the one word line WL 22.
Specifically, a connection relationship between the memory cells C and the word lines WL 22, the source lines SL 23, and the bit lines BL 25 will be described as follows.
The plurality of word lines 22 may connect gates of access transistors T of the plurality of memory cells C, and each of the two adjacent word lines 22 connects to gates of access transistors T arranged at different positions in the second direction.
For example, a second word line WL1 may connect to gates of access transistors T between a first bit line BL0 and a second source line SL1, between a second bit line BL1 and a third source line SL2, and between a third bit line BL2 and a fourth source line SL3, and a third word line WL2 may connect to gates of access transistors T between a first source line SL0 and the first bit line BL0, between the second source line SL1 and the second bit line BL1, and between the third source line SL2 and the third bit line BL2.
The plurality of source lines 23 may connect to sources or drains of the access transistors T of the plurality of memory cells C, and each of the plurality of source lines 23 may connect to sources or drains of access transistors T that alternately connect to different bit lines 25 along the first direction. For example, the second source line SL1 may alternately connect to sources or drains of access transistors T that connect to the first bit line BL0 along the first direction and access transistors T that connect to the second bit line BL1 along the first direction.
The plurality of bit lines 25 may connect to the drains or sources of the access transistors T of the plurality of memory cells C, and each of the plurality of bit lines 25 may connect to drains or sources of access transistors T that alternately connect to different source lines 23 along the first direction. For example, the first bit line BL0 may alternately connect to drains or sources of access transistors T that connect to the first source line SL0 along the first direction and access transistors T that connect to the second source line SL1 along the first direction. Herein, a bit line 25 is deemed to connect to drains or source of corresponding access transistors T through corresponding memories M.
Based on the connection relationship, when any one of the plurality of word lines 22, and any one of the plurality of source lines 23 or the plurality of bit lines 25 are selected, only one memory cell C may be selected. For example, when the third word line WL2, and the third source line SL2 or the third bit line BL2 are selected, the memory cell Cs between the second word line WL1 and the third word line WL2, and between the third source line SL2 and the third bit line BL2 may be selected.
When any one word line and any one bit line are selected in a typical magnetic memory element, a corresponding source line may be automatically selected. Additionally, when any one word line and any one source line are selected, a corresponding bit line may be automatically selected. In
The access transistor T constituting the memory cell C may control supply of current to the memory M while being turned-on or turned-off based on a voltage of the word line 22. For example, the access transistor T may be a MOS transistor or a bipolar transistor. The memory M constituting the memory cell C may include a magnetic material. For example, the memory M may include an MTJ element. The memory M may perform a memory function, based on the spin-transfer torque phenomenon in which a magnetization direction of a magnetic material is changed by input current.
For reference, the magnetic memory device, for example, a magnetic random access memory (MRAM) will be briefly described. In order to store states “0” and “1” in the MTJ devices that are memory devices included in the magnetic memory device, currents that flow through the MTJ devices must be bidirectional. That is, the current that flows through the MTJ devices when data “0” is recorded must be opposite to the current that flows through the MTJ devices when data “1” is recorded.
In order to form a structure in which currents of opposite directions flow, in the magnetic memory device, the source lines other than the bit lines exist. The bit lines and the source lines change respective potential differences with the MTJ devices and the access transistors (or cell transistors) of the memory cell interposed so that the directions of the currents that flow through the MTJ devices of the respective memory cells may be selected.
The magnetic memory device according to the inventive concepts may have a memory cell array structure capable of reducing or minimizing a size of unit memory cells while applying the method of using the separate source lines. That is, as illustrated in
In addition, since the memory cells are arranged so that two source lines share one bit line, the memory cells may be arranged in zigzags along the word lines WL 22 and the source lines SL 23 or the bit lines BL 25. Therefore, the size of the unit memory cells may be reduced or minimized.
For example, the magnetic memory element according to the present disclosure may have a unit memory cell Cu size indicated by a dashed-line rectangle. Specifically, when a pitch between the word lines 22 is 2 F and a pitch between source lines 23 or the bit lines 25 is 4 F, the unit memory cell Cu size may be 8 F2. Herein, F may denote a minimum lithographic feature size.
Since the memory cells are disposed in a zigzag manner along the word line 22, and the source line 23 or the bit line 25, and as illustrated, connect to the word line 22, the source line 23 and the bit line 25, only one memory cell may be selected by selecting any one word line and any one bit line (or any one source line).
A device for reproducing a recording medium on which the above sound source file structure 100 is recorded may include a sound source output device such as a song accompaniment device, a karaoke for business, a home karaoke device, a karaoke microphone, a smartphone, a set-top box, or a navigation device and the like.
Backings sounds, melody notes and lyric voices may be respectively converted into 0 or 1. For example, analogue-type backings sounds, melody notes and lyric voices may be respectively converted into 0 or 1 through an analogue-to-digital converter, and may be recorded on a recording medium 200 of the magnetic memory element as follows.
Referring to
A high voltage is applied to the third source line SL2, a low voltage is applied to the second bit line BL1, and an appropriate turn-on voltage is applied to the sixth word line WL5 so that a current path marked with an arrow is generated and the data “0” may be recorded in an MTJ device of the selected memory cell Cs. Here, the high voltage applied to the third source line SL2 may be 1.2V and the low voltage applied to the second bit line BL1 may be 0V.
However, the high voltage and the low voltage are example numerical values and the high voltage applied to the source line and the low voltage applied to the bit line are not limited to the above numerical values.
Referring to
A low voltage is applied to the third source line SL2, a high voltage is applied to the second bit line BL1, and an appropriate turn-on voltage is applied to the sixth word line WL5 so that a current path marked with an arrow is generated and the data “1” may be recorded in the MTJ device of the selected memory cell Cs. Here, the low voltage applied to the third source line SL2 may be 0V and the high voltage applied to the second bit line BL1 may be 1.2V.
That is, the voltages applied when the data “0” is recorded may be exchanged to record the data “1”. Therefore, in the memory cell array structure according to the present embodiment, data may be recorded on the MTJ element using the low operation voltage of about 1.2 V. Certainly, as stated in the description of the record of data “0”, the high voltage and the low voltage are provided only as an example and may vary.

The active region 21 may be defined on a substrate (not illustrated) by an isolation film (not illustrated). For example, the active region 21 may extend in an extension direction E marked with a bidirectional arrow and may be arranged at an oblique angle in a first direction (an x direction). For example, the active regions 21 may be arranged at a first angle θ corresponding to an acute angle in the first direction. In addition, as the active region 21 may be arranged at the oblique angle in the first direction, the active regions 21 may be arranged at the oblique angle in the second direction (a y-direction) vertical to the first direction.
Each of the active regions 21 may include a first region A1 and a second region A2 at both ends thereof. The first region A1 may be an area connecting to the source line 23, and may partially overlap the source line 23. The first region A1 may be a source or drain regions in terms of transistors. The second regions A2 connected to the bit lines 25 may partially overlap the bit lines 25. The second regions A2 may be a drain or source regions in terms of transistors. On the other hand, the second regions A2 of the active regions 21 may be connected to the bit line 25 through the variable resistance structures 24.
A plurality of active areas 21, as illustrated, may be disposed in parallel with each other in the first and second directions. An extension direction E of first line active areas 21 disposed along any one word line 22 in the second direction may cross an extension direction E of second line active areas 21 disposed along an adjacent word line 22. For example, the extension direction E of the first line active areas 21 may be orthogonal to the extension direction E of the second line active areas 21.
Similarly, first group active regions 21 arranged between one bit line 25 and a source line 23 adjacent to the one bit line 25 above the one bit line 25 in the second direction may be arranged so that an extension direction E thereof intersects that of second group active regions 21 arranged between the one bit line 25 and a source line 23 adjacent to the one bit line 25 below the one bit line 25 in the second direction. For example, the first group active regions 21 may be arranged so that the extension direction E thereof intersects that of the second group active regions 21 at right angle.
The active regions 21 may be formed into a semiconductor material layer constituting a substrate or into a semiconductor material layer additionally formed on a substrate. For example, the active area 21 may be formed into a silicon layer formed based on deposition or epitaxial growth on a substrate. The silicon layer, for example, may be a single crystal silicon layer or a poly silicon layer.
The plurality of word lines 22 may be extended in the second direction and disposed in parallel with each other in the first direction on the substrate, and each of the plurality of word lines 22 may be disposed across the plurality of active areas 21 disposed in the second direction and corresponding thereto, on the substrate. For example, each of the plurality of word lines 22 may be disposed across a central portion between the first area A1 and the second area A2 of each of the plurality of active areas 21 disposed in the second direction and corresponding thereto.
The word line 22 may include at least one of a doped semiconductor, metal, a conductive metal nitride, and a metal-semiconductor compound. A pitch between the word lines 22 may be 2 F in the first direction.
The plurality of source lines 23 may be extended in the first direction and disposed in parallel with each other in the second direction. Each of the plurality of source lines 23 may partially overlap and may electrically connect to the first area A1 of each of the plurality of active areas 21. For example, in each of the plurality of source lines 23, the first group active regions 21 arranged between the source line 23 and a bit line 25 adjacent to the source line 23 below the source line 23 in the second direction and the second group active regions 21 arranged between the source line 23 and a bit line 25 adjacent to the source line 23 above the source line 23 in the second direction may be arranged. The first regions A1 of the first group active regions 21 and the second group active regions 21 may be commonly and electrically connected to one source line 23.
Additionally, each of the first group active regions 21 and the second group active regions 21 may be crossed respectively by a different word line 22 in the first direction. Thus, just one active regions 21 among all the active areas included in the first group active regions 21 and the second group active area 21 may be selected as a result of selection of any one word line 22.
The source line 23 may include at least one of metal, a conductive metal nitride, a metal-semiconductor compound and a doped semiconductor. A pitch between the source lines 23 may be 4 F in the second direction.
The plurality of variable resistance structures 24 may be arranged to correspond to the plurality of active regions 21 in the first and second directions. The variable resistance structures 24 may be arranged below the bit lines 25 to be connected to the second regions A2 of the active regions 21 connected to the bit lines 25. That is, the variable resistance structures 24 may be arranged to correspond to the plurality of active regions 21, respectively, and may be electrically connected to the second regions A2 of the plurality of active regions 21, respectively.
Like the source lines 23, the plurality of bit lines 25 may be extended in the first direction and arranged in parallel with each other in the second direction. The plurality of bit lines 25 may be arranged to alternate with the plurality of source lines 23 in the second direction. Each of the plurality of bit lines 25 may partially overlap the second regions A2 of each of the plurality of active regions 21, and may electrically connect to the second regions A2. Each of the plurality of bit lines 25 may electrically connect to the second regions A2 of each of the plurality of active regions 21 through the variable resistance structure 24 arranged between the plurality of bit lines 25.
Each of the plurality of bit lines 150 may have a third group active regions 21 arranged between the bit line 150 and an adjacent source line 23 downward in the second direction, and a fourth group active regions 21 arranged between the bit line 150 and an adjacent source line 23 upward in the second direction. The second regions A2 of each of the third group active regions 21 and the fourth group active regions 21 may connect to a single bit line 25 commonly and electrically through corresponding variable resistance structures 24.
Additionally, each of the third group active regions 21 and the fourth group active regions 21 may be crossed respectively by a different word line 22 in the first direction. Thus, just one active regions 21 among all the active areas included in the third group active regions 21 and the fourth group active regions 21 may be selected as a result of selection of any one word line. The third group active regions 21 may correspond to the second group active regions 21 stated in the above description of the source line 23, and the fourth group active regions 21 may correspond to the first group active regions 21 stated in the above description of the source line 23. An upward direction of the second direction with respect to any one source line 23 may correspond to a downward direction of the second direction with respect to an adjacent bit line 25, and similarly, a downward direction of the second direction with respect to any one source line 23 may correspond to an upward direction of the second direction with respect to an adjacent bit line 25.
The bit line 25 may include at least one of metal, a conductive metal nitride, a metal-semiconductor compound and a doped semiconductor. A pitch between the bit lines 25 may be 4 F in the second direction.

The transparent plastic layer 510 may have a thickness of about 1.2 mm and transmit a laser beam.
The metallic reflection layer 520 may be mainly made of aluminum, and may reflect a laser beam passing through the transparent plastic layer.
The protection film 530 may mainly use polycarbonate. For the protection film 530, polycarbonate may melt into liquid and then a land 522 or a pit 524 representing 0 or 1 may be formed using a stamper. That is, the protection film 530 may include the pit 524 which is burned by a strong laser beam and the color of which turns opaque, and the land 522 which transmits a laser beam and the color of which is transparent, in polycarbonate. Accordingly, when a CD-ROM laser beam radiates to polycarbonate, the portion transparent may be read as the land 522 representing 1, and the portion burned and opaque may be read as the pit 524 representing 0.
As described above, the metallic reflection layer 520 made of aluminum may be coated on the transparent plastic layer 510 and may be coated with the protection layer 530 to create a CD.
In the recording medium 500 having the above structure, backing sounds of the backing sound source layer 110, 112, 114, melody notes of the melody sound source layer 120 and lyric voices of the lyric voice source layer 130 may be respectively recorded as 0 or 1.
To read data stored on the CD, a CD-ROM drive may irradiate a laser beam and measure a length of a path of a laser beam reflected from a surface of the metallic reflection layer 520 and passing through a lens and a Photo Director (a one-way reflection mirror), and a length of waves. In the land 522, almost all of the laser light may reflect without scattering, but in the pit 524, the laser light may diffuse.
The difference may allow light from the pit 524 to eliminate light from the land 522, and a reading mechanism may interpret this as 1. A portion with no change may be accepted as 0. In other words, portions changed from the land 522 to the pit 524 and changed from the pit 524 to the land 522 may be interpreted as 1, and portions that read the land 522 or the pit 524 may be interpreted as 0. Accordingly, when the land 522 or the pit 524 is short, time taken for reading may be short and the number of 0s may be reduced.
The land 522 and the pit 524 may include a minimum of 3 bits (or 90 nm) and a maximum of 11 bits (3300 nm). This is because each bit of data requires a length of about 300 nm on a spiral track.
When the pit 524 and the land 522 are just adjacent to each other, . . . may have continuity of pit-land-pit-land, and the continuity may be expressed as 11111. Accordingly, the continuity may not be sufficiently read using a laser beam. Thus, two pits need to be between three lands all the time, and this means that at least two 0s are between two 1s. However, the continuity of the pit and the land may not be excessively long, and a maximum length needs to be ensured. Thus, two or greater and ten or less 0s may be between two 1s.
However, within 1 byte, a minimum of 3 bits may not be ensured in a combination of 1 and 0, and within a plurality of bytes, a maximum of 11 bits may be exceeded. Thus, data may not be recorded on a CD-ROM in a 8-bit format used for storing data. To solve the problem, the CD-ROM may modulate 8-bit data into 14-bit pattern called a channel bit. This process is referred to as 8-to-14 modulation (Eight-to-Fourteen Modulation; EFM).
A decoder in the CD-ROM may modulate 8-bit data into 14-bit forms using an EFM conversion table. However, even in 14-bit bytes, continuous 1s that occur finally may not be prevented. This is the case where one ends with 1 and another one begins with 1. To prevent this from happening, three merging bits may be placed between bytes. Accordingly, 8-bit bytes usually used for a computer may require 1-channel bits in the CD-ROM.
In the above embodiment, a CD is provided as an example of the recording medium 500, but not limited. The recording medium may also be applied to an LP, a CD-RW, a DVD, a Blu-ray Disc (BD) and the like.
