Description

DIGITAL LANGUAGE STUDY APPARATUS HAVING AN AUTOMATIC REVIEW FUNCTION}

The present invention relates to a compressed voice file player (MP3, WMA, etc.), and more particularly, to a digital language unit having an automatic review function capable of protecting a finger joint.

More specifically, in the Cassette Tape language system, which most learners use for an hour or more per day for language learning, they can be quickly reviewed during playback for dictation or the like. When the button is pressed, an excessive force of about 2.1 kgf is applied, so excessive force is transmitted to the knuckles, and accordingly a large pressure is applied. In the present invention, in order to significantly reduce the force transmitted to the finger joints and the pressure felt accordingly, by reducing the number of use of the finger to protect the finger joints by automatically reviewing the order recently learned at the time of review, The present invention relates to an optimal digital language unit employing a push switch exclusively for language learning in which user convenience is optimally considered for efficient listening learning.

Today, the world is entering an era of infinite competition. Needless to say, Korea can only achieve sustainable growth through technological advancement and trade with foreign countries. Therefore, the necessity of foreign language education such as English is increasing. This is because there are more and more opportunities to meet and communicate with foreign people. In response to this trend, early language education has increased in recent years, and especially kindergarten and elementary school students have been studying language.

Linguistically, humans cannot speak unless they hear because of the brain structure. It's like how a baby learns language. For this reason, it is known that a native hearing impairment is almost impossible to learn to speak. Therefore, when learning a foreign language such as English for the first time, the most important thing is Listening including Dictation. For this, many people are known to use language learners. Currently, the language learner (ie, the language used mainly for dictation and listening) used by people who are learning foreign languages such as English is an analog portable cassette tape language machine. It's ironic to use analog portable cassette tape language in today's digital generation, but cassette tape language is fast forward during playback. / It has convenient functions such as review during playback. For this reason, most students and office workers studying languages have a portable cassette tape language (sometimes called "sticky"). Of course, there are many digital language classes that are generally classified as MP3 series language units and hybrid digital language units using cassette players and voice memory modules. However, despite these digital language devices being used, the main reason for using analog cassette tape language devices is to recognize the feeling of a button press when operating the Review / Cue function, which is not very accurate, Because you can listen immediately. In the case of using an analog cassette tape language in this manner, there is no need to find a very precise position, and there may be some errors.

This language term is mainly used for listening and dictation. The reason is that listening is the most difficult problem. Speaking, on the other hand, rather than relying on a semester, uses a group of three or four study groups of similar levels to define a topic. For English, for example, Time By selecting magazines such as Economist magazines, students can share their study contents in advance, study each time, and gather about 2 ~ 3 times a week to present 1 ~ 2 hours of presentation. . However, there are limits to using language to increase your speaking skills alone, and there are many cases where you give up shortly after starting, because speaking is only possible after you have fully digested your hearing.

In addition, several people with similar skills may be able to improve each other's ability by pointing out each other's faults. This is because it is not easy to correct a mistake by listening to your own voice. In other words, it is efficient to listen to the pronunciation of others and correct their pronunciation and accents. Various teaching methods, books, and learning files have been developed for efficient language learning. Especially, the time and money invested in foreign language learning are enormous. However, listening is the most basic, so if you have a digital language that can make listening and dictation convenient, I think it is possible to learn foreign languages quite efficiently.

However, the MP3 series of language devices currently available on the market can detect the time when the switch is pressed and control the user to quickly move to a desired position or to use the pre-section repeat function. In particular, the part that is hard to hear, especially when the user dictates, returns to that part and listens to it several times (about 7 times) repeatedly.

As such, the analog cassette tape language and the MP3 digital language language are widely used at present.

First of all, in the existing cassette tape language system, the fast send / replay button is used to move to the desired part during the playback. In this case, the stroke length is about 4.0 mm. Therefore, it is not very difficult to move to the desired position by the sense of the fingertip. On the other hand, in the digital language system adopting MP3, etc., since the tactile switch or soft button is used, the stroke distance that the fingertip can sense is very small, such as 0.1 to 0.25 mm, so that it can be moved to the desired position in proportion to the time pressed. It is quite difficult to move.

Therefore, taking advantage of the cassette tape language machine, the necessity of a digital language machine using a push switch having a stroke distance of 1.0 to 6.0 mm and an operating force of 50 to 800 gf is increasing. However, in a digital language class such as MP3, it is difficult to find a desired place by pressing a button such as rewind or fast forward during playback. The reason for this is that the size of MP3 language schools and the like is becoming smaller and lighter, and the size of the buttons is too small according to this trend, making it difficult to learn the sense of the fingertips when the buttons are pressed. In other words, it is difficult to learn the senses of the fingertips, and most of the time, playing the wrong place far beyond the position to find. Eventually, because they often go too far or do not reach the desired place, it is a phenomenon that these digital language devices are mainly used for music rather than for language learning.

In addition, even in the cassette tape type language that is commonly used, the magnetic head is pressed against the magnetic surface of the tape at the time of regeneration due to the physical characteristics of the moving part, and the tape is 4.76 cm / It is forced to run at the speed of second and at the time of Review / Cue, it is designed to run at the speed of 47.6cm / sec, which is 10 times the normal playback speed. In long term use, the magnetic material mainly composed of iron dioxide powder or chromium dioxide powder is peeled off from the polyester base film, which makes it difficult to permanently preserve the tape. In the case of digital players such as MP3s, the self-preservation of files for playback is permanent, but as mentioned above, even roughly finding the location of the part to be heard again (hereinafter referred to as 'the desired part') during playback. There is a problem that is difficult.

1 is a block diagram of a general digital language unit according to the prior art.

As shown in Fig. 1, a conventional general language controller includes a control unit (microcom) 1 with a built-in RAM, a display unit 2, a memory 3 for storing MP3 files, and an MP3 decoder (DAC (Digital to Analog Converter)). ; 5], a speaker / earphone jack 5, and a general language button 6 in which a play / fast forward / rewind is mainly implemented using a typical tact switch or a soft button.

In such a digital language class, such as MP3, because the ultra-small tact switch or the like is used in accordance with the trend of light and short, it is difficult for the user to adjust the time to press the switch to find the desired playback position. In order to solve this problem, the user has to repeat the process several times, such as finding the desired playback position by using the send back function of the MP3 player. In particular, in the case of learning a foreign language such as English, the time consumed is accumulated to interfere with the learning. The attention is focused on the button operation rather than learning, and the phenomenon that the attendant is inverted occurs. Therefore, the user needs to operate by looking directly at the indicator. However, if you are using a cassette tape type portable language machine, which is the most used type so far, you rarely see the indicator and simply operate the playback / pause / Review / Cue function with the thumb of one hand (in most cases, the left hand). With the other hand, take notes and write them. Due to this convenience, there is still a lot of analog cassette tape language learning.

By the way, such a tape language has the advantage that it is easy to find the desired playback position, but also has the following disadvantages. The biggest disadvantage is that, in addition to the problems of mechanical wear mentioned above and the possibility of finger joint damage due to excessive force applied to the finger joint during operation, the play time per tape is too short. That is, in the case of the tape language, the total playing time is about 60 minutes. Typically, it's only about 30 minutes per side (on the other hand, MP3 semesters can have hundreds of times more play time depending on their capacity), so if you need to review a tape you've already learned, you'll have to carry it with you. In addition, this causes the inconvenience of having to carry a bag at all times. In the case of dictation or the like, in order to wind the tape back and forth from time to time, the fast forward and fast forward buttons are frequently pressed during playback. At this time, since the magnetic tape passes at a speed of about 10 times (47.6 cm / sec) of 4.76 cm / sec, which is normal playback, in contact with the magnetic head of the cassette language, the magnetic particle coating surface of the tape is scratched. When used for a long time, deterioration of the magnetization force characteristic of the tape and sagging of the tape may occur.

In addition, when listening to the right hand, the left hand is mainly used for the thumb of the left hand, at this time, due to excessive physical force applied to the finger joint may cause abnormalities in the finger joints for a long time use. The reason for using the thumb is that when the button is pressed, a considerable force of about 2.1 kgf is required. These days, early language school education is on the rise, and kindergarten and elementary school students often study language. Because they are still in the process of growth, the development of two-handed thumb may lead to an imbalance if the finger is continuously subjected to about 2.1 kgf of force.

The actual force applied is about 2.1 kgf, which is quite a large force. In addition, since the area of the button in contact with the finger is only about 0.4 cm 3, the pressure felt by the finger contact surface becomes greater. This is because the pressure is usually inversely proportional to the contact area. In the worst case, callus may become hungry and have more serious consequences. Learners use an average of 30 minutes to 1 hour per day, and long-term intensive use can predict the possibility of local pain or abnormalities in the knuckle and wrist joints.

As described above, in the case of the Review / Cue button used in a conventional cassette tape language, the stroke is about 4.0 mm so that it is easy to sense the moving distance by the sense of the fingertips and to move it to the desired position sufficiently. On the other hand, the Tactile switch used in the digital language such as MP3 has a very small stroke distance of 0.1 to 0.25 mm, so that it is difficult to find a desired position in proportion to the pressing time.

Therefore, it is necessary to take advantage of the button use of the cassette tape language unit and overcome the disadvantages. Specifically, by using a push switch having a stroke distance of 1.0 to 6.0 mm (preferably 1.5 to 4.0 mm) and an operating force of 50 to 800 gf (preferably 300 to 500 gf), the pressed time of the switch is sensed. Accordingly, the necessity of a digital language unit that can dramatically reduce the force transmitted to the knuckle and the pressure felt by exerting proper control functions is increasing.

An object of the present invention is to solve the above problems, to dramatically reduce the force delivered to the finger joints and the pressure felt accordingly, and to review automatically in the order of recent learning even in review By protecting the finger joint by reducing the number of finger usage, and to provide an optimal digital language machine employing a switch for language learning dedicated to optimal user convenience for efficient listening learning.

Another object of the present invention is to provide a plurality of playback speed control buttons 15a to 15d or one speed control volume (not shown) so that the user can easily change the playback speed so that the playback speed can be varied. It is to make it possible.

In addition, another object of the present invention is to store a series of processes as a log file at the time of the first learning in order to automatically review in configuring a digital language semester in a memory, and to play files such as MP3 for later review. It is to be able to repeat automatically by using log file. In this case, the log file has a text file structure to minimize the file size.

According to an aspect of the present invention for achieving the above object, a fast send (Cue) switch during playback, a review switch during playback, a switch for playback, a stop switch and a pause In a digital language unit such as MP3, which has a (Pause) switch to perform playback and language learning functions,
During playback, cue (during playback) is provided by installing a push switch for language learning in which the stroke is 1.0 to 6.0 mm and the contact type is electro-electronic, electronic, or optical. Fast Forward) or Review (Rewind during Playback) function, and temporarily store a series of operation history of this push switch in RAM, and finally save it permanently in flash memory. When released, the history information in RAM is stored on the flash memory 3a as the final history file (study_1.log), and when the MP3 file (study_1.mp3) is played later, the review mode is selected by a separate selection switch. If selected, the digital language learner is characterized in that the language MP3 file (study_1.mp3) is played in the order stored in the history file.

In this digital language, the operating force of the push switch is in the range of 50 to 800 gf, the total area of the surface where the knob KNOB of the push switch contacts with the finger is 0.3 to 4.0 cm 3 or less, and the interval between the knobs is at least 0.2. It is preferable that it is mm or more.

In the digital language unit, when the push switch dedicated for language learning is locked, the language learning exclusive mode is displayed on the indicator, and when the review switch or the cue switch is pressed, the review / cue function is performed. In the pause mode when the dedicated push switch is released (OFF or RELEASE), pressing the Review switch jumps to the beginning of the previous file and immediately starts playing.The Cue switch moves to the beginning of the next file. Playback is immediately started, and in this state, when the push switch for the language learning-only push is locked, it is characterized in that the operation of re-entering the Review / Cue mode is executed.

In this digital language machine, when the distance between the push switch for exclusive use of language learning and the immediately adjacent review switch is between 8.0 and 18.0 mm, and the distance between the review switch and the cue switch is between 6.0 and 16.0 mm. In this regard, the distance between the playback switch and the review switch is larger than the distance between the review switch and the cue switch, and the mutual positions of these three switches are variable according to the structure of the language.

In addition, the digital language unit of the present invention is composed of a switch for reviewing language learning in the form of a push switch common or separate from a button for general music, a review switch and a cue switch, and a language separate from the button for general music. Configuration with multiple or one multi-function repeat button dedicated to learning, configuration with multiple playback speed control buttons or volume for one speed control, separate from general music buttons, or Either or a combination of the configurations having a separate dedicated or common multifunction automatic review dedicated switch for executing the automatic review function may be provided.

Furthermore, according to another aspect of the present invention, when giving a history file name related to automatic review, it has the same file name as the language file name and has a separate extension, the history file has a text file structure, the format stored in the file A digital language learner is provided in the same order and arrangement as the table structure on the memory, and has a file format in which various switch input states are recorded on the basis of the elapsed time after playback or stored on the basis of an address on the RAM.

In this digital language device, it is preferable to generate and store another history file having the same file name as the language file name and having a bak or other extension in case of accidental deletion of the history file name for automatic review.

According to the present invention, in order to protect the finger joints, the push switch (see Fig. 23) having an optimal stroke and sensing force without applying excessive force to the finger during operation is found and applied to the language unit, and the audio file storage of the language unit The setting mode and the set mode in which the learner selects the characteristics of the present invention in the part (3) and the storage location (3a) of the history file recording the corresponding time, the operation sequence of the switch related to the language-only switch, and the automatic review method. It is a process of regeneration. In the pre-repeated section and the normal section repeat playback setting, a guard band for 0.5 to 1 second is added and stored in the memory 7 before and after the actual section.

When the Review (9) or the Cue Switch (10) is pressed while the language exclusive playback switch is pressed, the time when the switch is pressed is stored in the RAM memory (7), and N times the normal time (normally N =). It moves to a position on the memory 7 corresponding to the time of 10) and starts playback from that portion (see Fig. 12). In the case of the language-only reproduction mode 8 as a whole, the silent portion can be selectively inserted about 0.5 to 1.0 second at the time of reproduction as finally set in the actual memory. The reason is to distinguish between the beginning and the end of the file. Here, the time of 0.5 to 1.0 second can be varied and set as desired from 0.0 second to 10 seconds in the configuration menu of the learner.

In addition, according to the present invention, the optimum according to the age of the user to protect the finger joints from excessive force of about 2.1kgf applied to the operation of the Review / Cue button (Fig. 30), which has been the biggest problem when using a conventional cassette tape language. Detecting the pressed time of the switch used for the selection and learning of the push switches 8 to 10 having the stroke distance 18 of FIG. 3 and the operating force (see 17, 23 of FIG. 3); The optimal micro-learning effect can be obtained through the control microcomputer (1) to properly utilize this for learning. In addition, a plurality of line segment repeating buttons 14a to 14d are provided so that the user can easily repeat the section, and play the section immediately after playing a section corresponding to a predetermined time without continuously playing back the language file. End of file continuously by starting playback from the point of time which has been separated from the starting point of the section and repeating it several times (in the case of the present invention, four times) and starting playback from the point of time which is away from the point of time. You can play until.

According to the present invention as described above, the language learning dedicated switch (8 to 10) of the operation pattern and the appropriate stroke length 18 and the operating force (17; Fig. 23) suitable for the age group is selected in consideration of the age group used in the digital language. Therefore, even when used for a long time there is an effect that can protect the finger joints and wrist joints from being overwhelmed.

In addition, in the case of reviewing a language file that was once learned later, it is possible to automate the learning by using the corresponding history file which is finally recorded, thus saving time required for switch operation during learning and focusing only on learning. It also has the effect of improving learning efficiency.

In addition, when the section repeat 14 and the normal section repeat operation, if the section is extended and played back to the part corresponding to about 0.5 seconds to 1.0 second (variable setting in the configuration menu) before and after the section where the actual playback sound is heard, It is possible to prevent the desired section from being cut off at the time of output. In other words, if the part you want to listen to is suddenly replayed during listening practice, it is very likely that you will not be able to hear it properly. Therefore, by providing a spare section back and forth than the section you want to listen to may provide the learner with time to improve the learning efficiency.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. The same reference numerals are used for the same elements in the drawings, and redundant description thereof will be omitted.

First, in the embodiments of the present invention to be described, the term "language" or "language term" is to be understood as meaning a generic term for a device for learning a foreign language, such as English, Chinese, Japanese. In addition, the term "RAM" refers to volatile memory that loses data when power is not supplied, such as SDRAM, DRAM, and SRAM, and the term "ROM" does not require power supply such as NAND FLASH, NOR FLASH, or EEPROM. It means non-volatile memory that does not lose data. Broadly speaking, data recorded on hard disks, magneto-optical disks, and the like can also be included. The term " MP3 file " means not only the MP3 format but also digital audio files such as WMA and WAV.

2 is a block diagram of a digital language unit to which the conceptual configuration of the present invention is applied.

As shown in Fig. 2, the digital language machine of the present invention has added a component 16 necessary for language learning to an existing digital language machine (Fig. 1). In detail, the digital language unit of the present invention includes a flash memory area including MP3 files and the like, having switches for language learning dedicated 8 to 13 and buttons for language learning 14-14. The new language can be referred to as a digital language terminology that allocates and utilizes a specific region 3a.

In the case of the existing general language (FIG. 1), as a user interface, the play / fast forward / rewind etc. are mainly implemented by using a general button 6 such as a typical tact switch or a soft button.

In the digital language unit of the present invention, a general button 6 such as a play button, a fast-forward button, a rewind button, and the like, which has been generally used in a basic MP3 language machine or an MP3 player, is used for the user's convenience, but additionally, a large 3.5 mm Install a dedicated language learning switch with a push switch with a stroke. The biggest motivation for making this idea against the trend of miniaturization of digital devices is that the convenience of learners who use a language course is considered first. In fact, when searching for the inconvenience of using a digital language term through the Internet, the most uncomfortable thing is that there is no "squishy" function. In this way, learners using the digital language learner are feeling very inconvenient to use the small buttons, and this disadvantage has not been solved.

In the present invention, in order to solve this disadvantage, the conventional general button (6) is used when playing music, the language learning dedicated playback switch (8), rewind switch in the form of a push (PUSH) switch when learning (9) and the fast forward switch 10 are used. That is, when the regeneration switch 8 dedicated to language learning is pressed, the perturbator 8d of the regeneration switch 8 comes into contact with the two contacts 8a and 8b so that electricity flows as shown in FIG. 3. It is in a state. During language learning, as shown in FIGS. 4 and 5, a review switch is used to select a portion of the language MP3 file stored in the memory 3a that is hard to be heard during playback, or a portion that is not heard or difficult to hear while writing. Press (9) or Cue switch (10) to rewind several times to learn.

When the Review switch 9 or Cue switch 10 is pressed during playback, the elapsed time is stored in the memory 7, and when the Review switch 9 or Cue switch 10 is turned off (OFF), the memory 7 Playback is started by moving to the previous or later position corresponding to N times the elapsed time (typically N = 10) stored at. For example, if the pressed time is 1 second, the playback moves to the part before 10 seconds or after 10 seconds to start playback. In the case of the cassette tape language school still used by most people, the elapsed time of hand pressing and the time the actual tape has traveled during the review and cue operation are calculated and calculated, and it runs about 10 times faster. In view of this point, in the present invention, N is set to 10. Even if you press the Review / Cue button very briefly, it will be pressed for about 0.1 seconds, and the tape will actually run for about 1 second. If the push switch with 3.5 stroke stroke is used, the operation will be almost similar to that of the tape language. If the push switch with 4.0 stroke stroke has a long distance, it is necessary to set the value of N to 12-13. do. Of course, since it is also closely related to the operating force of the spring used for the switch, the stroke length is appropriately set in consideration of this point.

12 shows an example of the operation when the Review and Cue buttons are pressed. 18 and 19 show flow charts for operations when the Review and Cue buttons are pressed.

For example, suppose that the song "Can't Falling In Love With You" by the American singer Elvis Presley is stored in the FLASH memory 3 as a language learning file having a file name of study_1.mp3.

The operation of Fig. 12 will be described in detail with reference to Fig. 11 showing an example of the contents of the memory. When the language exclusive playback switch 8 is turned ON, playback of the language file is started. If the Cue switch 10 is pressed for 1 second after 4 seconds have elapsed since the start of playback (the end of playback of the " SAY " portion of the memory contents in Fig. 11), the return time is 15 seconds longer than the playback time. In this case, playback starts from "CAN'T" in the memory contents and proceeds to the portion corresponding to 28 seconds ("YOU"). If the review switch 9 is pressed for 2 seconds at the time when 24 seconds have elapsed during the playback (the end of the playback of the part called "LOVE"), the return is made 20 seconds before the pressed time (2 seconds). The playback returns to the start point (part "ONLY") and starts playback.

In the above description, the value of N is variable and can be set on the configuration menu of the digital language semester according to the present invention. When using a switch with a stroke length of 3.5 mm, the Review switch 9 or the Cue switch 10 may be pressed deeply to the end (about 3.0 to 3.5 mm), but slightly pressed (1.0 to 2.0 mm). There may also be. When pressed slightly (1.0 to 2.0 mm) in this manner, the learner is momentarily pressed (half-touch state), so that the corresponding operation is performed.

The review switch 9 and the cue switch 10 are each configured in the form of two contacts. In general, the operation of the review switch 9 is a slider 9d attached to the contact 9b and the contact 9c, and when pressed gently, it is pressed halfway (half touch). The perturbator 9d is attached only to the contact 9b and is not attached to the contact 9a or the contact 9c. At this time, after the elapsed time in the state where the contact is separated is stored in the RAM memory 7 in the microcomputer 1, when the switch 9 is returned to its original position (the oscillator is attached to the contact 9b and the contact 9c again ( Short-circuit state), it moves to a place corresponding to N times (N = 5) times the time stored in the memory 7, and starts playback.

The same applies to the operation in the half-pressed state (half touch state) using the cue switch 10. That is, in the operation of the cue switch 10, the perturbator 10d is normally attached to the contact 10b and the contact 10c, and when pressed lightly, it is in a half-pressed state (half-touch state), thereby causing the perturbator 10d. Is attached only to the contact 10b and is not attached to the contact 10a or the contact 10c. At this time, after storing the elapsed time in the state where the contact is separated in the RAM memory 7 in the microcomputer 1, when the switch 10 is returned to its original position (the moderator is attached to the contact 10b and the contact 10c again ( Short-circuit state), it moves to a place corresponding to N times (N = 5) times the time stored in the memory 7, and starts playback. Here, the value of N is variable and can be set on the preference menu of the language semester according to the present invention.

The half touch operation will be described in detail with reference to FIG. 11. After the Cue switch 10 is pressed halfway for 1 second (after half-touch) in the 19 second portion (the point at which the end of the portion called "HELP" is finished), the half touch operation is returned. If you do so, it moves to the point corresponding to 5 times of 1 second and starts playback in the 25 second part (the starting point of "WITH"), and at the end of the 24 second part (the end point of "LOVE" part) during the playback, If the review switch 9 is pressed halfway for 2 seconds (after half-touching) and then returned, the playback returns to the 15-second portion (the starting point of "CAN'T"), which is 5 times the 2 seconds.

Here, if the automatic review selection switch is set to the recording position 11 for convenient use in the future review, a series of processes for the operation of the Review switch 9 or the Cue switch 10 generated during the study as a log file will be displayed. You can save it. To exit the recording mode, press the play switch 8 again to enter the pause mode or set the automatic review selection switch to the stop position 12. At this time, the history file of the TEXT file format Log file) is generated and stored in the flash memory 3a. The reason for the text file format is that it has the smallest capacity and the best efficiency in file compression.

Fig. 16 shows a flow chart for explaining the storage of the history file. In this case, assuming that the stored history file (Log file) is study_1.log, the internal structure of the history file (Log file) is as shown in FIG. The method of giving the history file name is the same as the method of giving the language file name, but the extension of the file is log. This is to make it easier to find the file during the automatic review. In addition, in case of accidental deletion of the log file, a backup file, for example, an extension of bak, may be additionally created for backup purposes.

Later, when you want to review the MP3 language file (3) called study_1.mp3, set the automatic review selection switch to the automatic review position (13) and press the language playback switch (8) to enter the playback mode. 3) A log file called study_1.log, which is a history file corresponding to the corresponding MP3 file stored in 3), is searched in the memory 3a. If the study_1.log is not deleted by mistake, the file called study_1.bak is stored in RAM memory ( 7), the memory is stored in the RAM memory 7 in the form of a table, and then controlled by the microcomputer 1 in the order stored in the table, thereby enabling automatic review. An example of this typical table is shown in FIG. 15.

For reference, because of the characteristics of language learning, the part which is not understood once is often not understood again even if reviewed later. Therefore, even if you do not press the Review switch 9 or Cue switch 10 one by one has the advantage that the review can be automatically convenient. 17 shows a flow chart for this automatic review operation.

When the review mode is to be canceled during the automatic review, the review selection switch may be set to the stop position 12. The automatic review mode is canceled, and the reproduction mode for the language learning is entered.

In general, when receiving or writing, the parts which are hard to hear are often repeatedly heard several times (about 4 to 7 times in the case of the present invention). Since voices from news and the like are generally very fast, the speed of handwriting in the case of dictation is relatively slow. In such a case, it is necessary to listen to the same section repeatedly. However, in the case of general MP3 language language, to set the desired section repetition, it is simply set by using a section repeat (usually A <---> B) dedicated button (not shown). In such a case, as described above, it is difficult to check whether the setting is made properly, and in most cases, the section repeat-only button is so small that it is necessary to look at the corresponding flag on the LCD display to make sure that the setting is made correctly. .

In order to overcome these drawbacks, the language unit of the present invention is provided with four separate dedicated section 14 for learning language lines. For example, a two-second segment button 14a for replaying seven times from the point in time two seconds ago that has already passed on the basis of the current point of view, and the section from the point in time four seconds ago to the present seven times 4 seconds of segment button 14b for repeated playback, 10 seconds of segment button 14c for playback 7 times from 10 seconds ago, and 7 times of playback from 20 seconds ago The line segment button 14d for 20 seconds is provided. Of course, when the interval repeat playback is completed, the normal playback mode is returned. Here, too, in detail with reference to Fig. 11 showing an example of the contents of the memory and Fig. 13 for explaining the line segment repetitive operation, for example, the current playback position has just finished playing at the end of 18 seconds ("HELP" playback). End point), pressing the four-second segment button 14b returns to the point four seconds ago and starts playback from the 15-second portion (the portion of "CAN'T"), followed by the 18-second portion ("HELP"). Repeat seven times and return to playback mode. In order to cancel the repeat section mode, the review switch 9 or the cue switch 10 dedicated to language learning can be pressed. It is needless to say that the time setting of each of the line segment buttons 14a to 14d can be set to any time on the environment setting menu of this semester.

As another automatic repeat playback method, a language file is repeatedly played N times (N = 4 is the default setting and the value of N can be arbitrarily changed) repeatedly for one language file. There is a method of continuously performing this operation until the end of the file, while rewinding and replaying a section corresponding to a predetermined time from that point again N times. By adopting this method, the learner can concentrate on listening by listening to the ear without using the left hand to operate the device while listening or writing. Rather, it can significantly increase learning efficiency.

Press and hold the line segment repeat button 14 to enter this automatic repeat play mode. According to the default setting, for example, if the button 14a is pressed for more than 0.5 seconds at the time 4 seconds after playback, the 5 seconds section is played four times repeatedly, then the 4 seconds are rewound and the 5 seconds section is immediately Play four times, rewind four seconds, and play five times five times immediately. Playback continues. In this case, press and hold the button 14b for 0.5 seconds or longer to play the 10-second section four times, rewind 8 seconds and repeat the 10-second section four times, and then rewind 8 seconds to 10 seconds. The section is played back four times to the end of the file. If the button 14c is pressed for 0.5 seconds or longer, the 15 second section is repeatedly played four times, and then the 12 second is rewound and the 15 second section is repeatedly played four times. If the button 14d is pressed for 0.5 seconds or longer, the 20 second section is repeatedly played four times, and then 16 seconds are rewound and the 20 second section is repeatedly played four times.

Herein, the operation in the case where the button 14d is pressed will be described in detail with reference to the contents of RAM (Fig. 11). When pressed for 1 second, the "ONLY FOOL RUSH-IN BUT I CAN'T HELP FALLING IN" section is played four times and then the "FOOL RUSH-IN BUT I CAN'T HELP FALLING IN" section is played four times. (8 seconds to 22 seconds) is repeatedly played four times, and the "BUT I CAN'T HELP FALLING IN LOVE" section (11 seconds to 25 seconds) is repeatedly played four times, and "I CAN'T HELP is played." FALLING IN LOVE WITH YOU "section (14 seconds to 28 seconds) is played four times and then stops.

Press and hold button 14d for 0.5 seconds or longer to play the 20-second section four times, rewind 16 seconds and repeat the 20-second section four times, and then repeat the 20-second section four times, and The same operation is continued until the end of the file, such as rewinding the second and playing the 20 second section four times.

One of the important things in language learning is the speed of reproduction. In some cases, it may be necessary to play slowly or quickly. This is because, in the case of fast news or conversation, you may hear it slowly. In addition, if you have some skill, you may need to hear faster than normal speed. Conventional digital language units have this function, but most of them have only one button, so each time you press this button, you hear the variable speed. However, even in such a case, it is difficult to distinguish how many times the speed is achieved without directly looking at a corresponding flag in the LCD display.

In order to overcome this disadvantage, the digital language unit of the present invention is provided with four playback speed control buttons 15a to 15d separately for controlling the playback speed, so that one-touch playback speed can be selected. For example, the playback speed is 0.7 times for the button 5a, 1 times speed (normal speed) for the button 15b, 1.3 times speed for the button 15c, and 1.8 times speed for the button 15d. This is making it possible. Here, needless to say, the speed setting of each of the playback speed control buttons 15a to 15d can be set at an arbitrary speed on the preference menu of the language learner according to the present invention.

On the other hand, if the listening practice is set to play directly from the part to be listened to, there is a possibility that the learner is embarrassed and cannot understand the beginning part properly. For this reason, when performing line segment repeat 14 and general segment repeat (not shown), about 0.5 seconds to 1.0 second before and after the section where the actual playback sound is recorded (of course, this time can also be changed in the configuration menu). It is possible to enlarge and play the section with a spare section. In this way, by inserting the spare section before and after the original section, it is possible to prevent the phenomenon that the desired section is cut at the time of output, and also to increase the learning efficiency by providing the learner with the time to prepare.

In addition, in the line segment repeat mode and the normal segment repeat mode (not shown), a silent portion may be inserted at the front and back portions 0.5 to 1.0 seconds selectively during playback as finally set in the real memory 7. Here, the method of inserting the silent portion can be largely divided into two. One is digital and the other is analog. First, a digital method is a method of delaying the output of a decoder which decompresses a compressed file such as an MP3 before passing it to the DAC. The analog method is to mute by using a transistor, a field effect transistor (FET), a relay (RELAY), etc. at a DAC output terminal or an audio final output terminal (earphone or speaker terminal). The reason is to distinguish between the beginning and the end of the file. Here, the time of 0.5 to 1.0 second can be varied and set as desired from 0.0 second to 10.0 second in the environment setting menu of the learner.

As described above, according to the present invention, the force transmitted to the finger joints and the pressure felt according to the present invention can be drastically reduced, and the finger joints can be reduced by reducing the number of times of finger use by automatically reviewing the order recently learned even during the review. It is possible to provide an optimal digital language unit that adopts a switch for language learning that considers the user's convenience optimally.

In addition, a plurality of playback speed control buttons 15a to 15d may be provided to change the playback speed so that the user can easily change the playback speed.

In addition, in order to automatically review the digital language semester, a series of processes are stored in the memory as a log file at the time of the first study, and a log file is selectively used when playing a file such as MP3 for later review. It is also possible to repeat automatically.
