Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view schematically illustrating a portable audio player according to a preferred embodiment of the present invention. The audio player of FIG. 1 includes a memory 10 and a sound reproducing unit 20 connected to a central processing unit 60. The memory 10 stores audio information files of various contents. The audio information file includes digital data in which sound signals and / or voice signals related to music have been converted, or digital data in which voice signals relating to digital data or other information in which voice signals related to language learning have been converted.

The sound reproducing unit 20 restores the sound and / or the voice from the digital data stored in the memory 10 and outputs the reconstructed sound and / or the voice. To this end, the sound reproducing section 20 has a codec 22 connected to the memory 10 and the CPU 60 via a bus line BL and an amplifier 24 connected in series with the codec 22. And a speaker 26. The codec 22 decodes digital data for audio information from the memory 10 to restore analog sound and / or voice signals. The analog sound and / or voice signal recovered by the codec 10 is amplified by the amplifier 24 to have sufficient power. The analog sound and / or voice signal amplified by the amplifier 24 is converted-output by the speaker 26 into sound and / or voice.

The portable audio player also includes a key input section 30 and a display section 40 which are commonly connected to the central processing unit 60 via the bus line BL. The key input unit 30 inputs a command and information desired by a user. The key input unit 30 supplies the input command and information to the CPU 60 in the form of key data. In order to input commands and information from the user, the key input unit 30 is provided with a limited number of keys. For example, a power-on / off key, a fast forward key, a reverse key, an up and down key, etc. for designating the basic operation of the audio player are provided in the key input unit 30.

The display unit 40 controls character data (e.g., lyrics data, character data for language content, audio information) about audio information (e.g. music) supplied from the memory 10 under the control of the CPU 60. The file name of the file) is displayed on the screen. In addition, data on the operating state of the portable audio player supplied from the CPU 60, input commands and information, and the like are displayed. As the display unit 40, a liquid crystal display module, an electroluminescence display module, a cathode ray tube display module, and the like may be used, but a liquid crystal display module is preferable.

Furthermore, the portable audio player may include a relay unit 50 connected to the CPU 60, a key input unit 10, and a power supply unit 70 supplying the first driving voltage VDD1 to the CPU 60 through the bus line BL. ). The relay unit 50 relays communication between the CPU 60 and an external database (for example, a computer system) or relays communication between the CPU 60 and an external communication network such as the Internet. Through the relay unit 50, the CPU 60 downloads audio information files and text data files for music information and language learning information from an external computer system or communication network. The CPU 60 causes the downloaded audio information files and the text data files to be stored in the memory 10.

The power supply unit 70 supplies the first driving voltage VDD1 to the CPU 60 and the key input unit 30 at all times. In addition, the power supply unit 70 supplies a second drive to be supplied to the memory 10, the sound reproducing unit 20, the display unit 40, and the relay unit 50 in response to the voltage control signal CVS from the CPU 60. The voltage VDD2 is controlled. The voltage control signal CVS has a specific logic value (eg, high logic) when the portable audio player is powered on. When the voltage control signal CVS has a specific logic value, the power supply unit 70 supplies the second driving voltage VDD2 to the memory 10, the sound reproducing unit 20, the display unit 40, and the relay unit 50. do. On the other hand, when the voltage control signal CVS maintains the base logic value (eg, low logic), the power supply unit 70 may include the memory 10, the sound reproducing unit 20, the display unit 40, and the relay unit ( The second driving voltage VDD2 to be supplied to 40 is cut off.

The CPU 60 decrypts the commands and information input by the user from the key data from the key input unit 30. In accordance with the decoded instructions and information, the CPU 60 selects the circuit sections (ie, the memory section 10, the sound reproducing section 20 and the display section 40, the relay section 50, etc.) in the portable audio player. The control is performed to perform an operation such as playing and stopping a user-specified audio information file (for example, music). In addition, the CPU 60 allows the audio information files downloaded from the external database or the communication network through the relay unit 50 to be stored in the memory 10. In other words, the CPU 60 performs operations of all circuits inside the audio player such as the memory unit 10, the sound reproducing unit 20, the key input unit 30, the display unit 40, the relay unit 50, and the like. Function as a control unit for controlling.

In addition, the portable audio player according to the embodiment of the present invention further includes a key mode management module 62 implemented to be included in the CPU 60. This key mode management module 62 can be implemented by a program of the same procedure as the flowchart shown in FIG. 2 operated by the CPU 60. The key mode management module 62 has some keys (e.g., fast forward key, reverse key and up key) on the key input unit 30 when the key data for the power-on command is input from the key input unit 30. Etc.) to designate language-specific additional functions (e.g., automatic fuzz-play function, repeat play function and speaker select play function, etc.). In order to dedicate some of the keys to the language-specific additional function, the key mode management module 62 displays a message asking whether to set the language key mode in response to a power-on command. Mark on. In addition, the key mode management module 62 sets the language key mode when the key data related to the language key mode setting command is input from the key input unit 30 so that some of the keys on the key input unit 30 are dedicated to the language. Make it dedicated to the assignment. In the language key mode, the key mode management module 62 controls the memory 10 and the sound reproducing unit 20 to perform language-specific additional functions corresponding to the key data in response to the key data for the restricted keys. . If the language key mode is not set, the key mode management module 62 responds to the key data for some of the dedicated keys that can be used for the basic functions of the portable audio player corresponding to the key data (e.g., fast forward playback, Backward progress, cursor up, etc.).

Alternatively, the key mode management module 62 may be implemented by a program of the same procedure as the flowchart shown in FIG. 3 operated by the CPU 60. When the key data for designating a command or information is input from the key input unit 30 during the reproducing operation (i.e., while in the reproducing mode), the key mode management module 62 returns the audio information file being reproduced to the music information or the like. Determine whether information for language learning is included. The determination of the type of the audio information file being played back depends on the logical value of the user index code recorded in the other index area of the header information for the audio information file as shown in FIG. If the logical value of this user index code is reset to "0", the key mode management module 62 determines that the audio information file of the music information is being reproduced. In contrast, if the logical value of the user index code is set to "1", the key mode management module 62 determines that the audio information file of language learning information is being reproduced. The user index code is set or reset by the producer or user of the audio information file through an information handling system such as a personal computer and a notebook computer. In addition, the user index code on the other index area of the header information of the audio information file may be set or reset by the CPU 60 responding to the user's designation when the audio information file is recorded in the memory 10. .

If it is determined that the audio information file of the language learning information is being reproduced, the key mode management module 62 causes some of the keys (eg, the fast forward key, the reverse key, and the up key, etc.) on the key input unit 30 to be language-set. Dedicated to specify dedicated additional functions (e.g., automatic fuzz-play function, repeat play function, speaker select play function, etc.). For example, if key data for any one of some keys (ie, fast forward key, reverse key and up key, etc.) on the key input unit 30 is input during reproduction of the audio information file of language learning information, the key The mode management module 62 controls the memory 10 and the sound reproducing unit 20 to perform a language-specific additional function corresponding to the key data in response to the key data for the restricted keys. When playback of an audio information file of music information other than language learning information is detected, the key mode management module 62 responds to the key data for some of the dedicated keys, and the basic functions of the portable audio player corresponding to the key data (e.g., For example, fast forward playback, backward progression, cursor up, etc.) are performed.

In this way, the key mode management module 62 causes some of the keys on the key input unit 30 to receive commands for different functions according to the key mode. Accordingly, the portable audio player according to the embodiment of the present invention may enable the selection of more functions than the number of keys by the limited number of keys. In addition, the portable audio player according to the embodiment of the present invention enables the selective control of language-only additional functions without separate keys.

2 is a flowchart illustrating a step-by-step method of controlling a portable audio player according to an embodiment of the present invention. The flowchart of FIG. 2 is performed by the CPU 60 shown in FIG. 1 to allow the key mode management module 62 to be implemented. Thus, the flowchart of FIG. 2 will be described in detail in conjunction with FIG.

In step S10, the CPU 60 waits until key data for a power-on command is input from the key input unit 30. When the key data for the power-on command is input from the key input unit 30, the CPU 60 supplies the power supply unit 70 with a voltage control signal CVS of a specific logic value (e.g., high logic) ( Step S12). The power supply unit 70 responding to the voltage control signal CVS having a specific logic value supplies the second driving voltage VDD2 to the memory 10, the sound reproducing unit 20, the display unit 40, and the relay unit 50. To allow the portable audio player to be driven. The CPU 60 supplies the language key mode setting request message to the display unit 40 such as "The language key mode can be set to use the language-specific additional function by setting the language key mode." Ask the user to set the language key mode through the screen. Further, the CPU 60 sets a timer assigned to any one of the registers in the CPU 60 so that the period for setting the language key mode can be counted (S14). Until the set timer is reset, the CPU 60 checks whether the key data for the setting command of the language key mode is input from the key input unit 30 (steps S16 and S18). When the key data for the language key mode setting command is input from the key input unit 30, the CPU 60 sets the logical value of the language key mode flag assigned to any one of the registers in itself to " 1 " The key mode is set (step S20).

After the timer is reset in step S18 or after setting in step S20, the CPU 60 waits until key data is input from the key input unit 30 (step S22). When key data is input from the key input unit 30, the CPU 60 checks the logical value of the language key mode flag to determine whether the language key mode is set (step S24). If the logical value of the language key mode flag is " 1 " Or the like) is checked (steps S26 to S30). For example, if the key data input in step S26 corresponds to the fast forward key, the CPU 60 causes the read operation of the memory 10 to be performed in the form of alternating with a rest period of a predetermined period (ie, automatic The fuzz-play function is performed) (step S32). In this case, the sound reproducing unit 20 does not periodically output sound and / or voice, so that the fuzz state and the reproducing state are alternated. Accordingly, the user can follow the voice output from the sound reproducing unit 20. As another example, when the key data input in step S28 corresponds to the reverse key, the CPU 60 causes the memory 10 to repeatedly read the digital data for the audio information stored in the storage area of the predetermined section ( Step S34). In this case, the sound reproducing unit 20 repeatedly outputs the same sound and / or voice. As another example, when the key data input in step S30 corresponds to an up key, the CPU 60 causes the sound reproducing unit 20 to correspond to audio data of voices of two speakers from the memory 10. In step S36, the voice signal of any one of the voice signals is muted. Accordingly, the sound reproducing unit 20 can practice responding to the output voice.

The key data input in steps S26 to S30 does not correspond to any of the specific keys (for example, a fast forward key, a reverse key, or an uplink key), or the logical value of the language key mode flag is changed in step S24. If " 0 " (i.e., not in language key mode), the CPU 60 checks whether the input key data corresponds to the power-off key (steps S38 and S44). If the key data input in steps S38 and 44 correspond to the power-off key, the CPU 60 resets the logic value of the language key mode flag to "0" to cancel the language key mode and the power unit 70. In step S40, a specific logic value (e.g., high logic) of the voltage control signal CVS, which is supplied to the control panel, is transitioned to a base logic value (e.g., low logic). Then, the power supply unit 70 supplies the second driving voltage VDD2 supplied to the memory 10, the sound reproducing unit 20, the display unit 40, and the relay unit 50 in response to the voltage control signal having the base logic value. ) To power off the portable audio player. If the key data input in step S44 does not correspond to the power-off key, the CPU 60 causes the memory 10, the sound reproducing unit 20, and the display unit 40 to perform an operation according to the input key data. And at least one of the relay unit 50 (step S42). If the key data input in step S38 does not correspond to the power-off key or after performing step S42, the CPU 60 returns to step S22.

3 is a flowchart illustrating a step-by-step method of controlling a portable audio player according to another embodiment of the present invention. 3 is performed by the CPU 60 shown in FIG. 1 to allow the key mode management module 62 to be implemented. Thus, the flowchart of FIG. 3 will be described in detail in conjunction with FIG. 1.

In step S50, the CPU 60 waits until key data is input from the key input unit 30. When key data is input from the key input unit 30, the CPU 60 checks which one of the audio information files stored in the memory 10 is reproduced through the sound reproducing unit 20 (step S52).

If it is determined in step S52 that any one of the audio information files on the memory 10 is being played back, the CPU 60 may determine a user index code on the other index area of the header information of the audio information file being played back from the memory 10. (Step S54). The CPU 60 checks whether the audio information file being reproduced contains language learning information or music information based on the logical value of the read user index code (step S56).

If it is determined in step S56 that the audio information file being played back contains language learning information (that is, if the logical value of the user index code is set to "1"), then the CPU 60 inputs the key data into specific keys. (E.g., a fast forward key, a reverse key, an uplink key, etc.) is checked (steps S58 through S62). For example, if the key data input in step S58 corresponds to the fast forward key, the CPU 60 causes the read operation of the memory 10 to be performed in the form of alternating with a certain period of rest (i.e., automatic The fuzz-play function) (step S64). In this case, the sound reproducing unit 20 does not periodically output sound and / or voice, so that the fuzz state and the reproducing state are alternated. Accordingly, the user can follow the voice output from the sound reproducing unit 20. As another example, when the key data input in step S60 corresponds to a reverse key, the CPU 60 causes the memory 10 to repeatedly read digital data about audio information stored in a storage area of a predetermined section ( Step S66). In this case, the sound reproducing unit 20 repeatedly outputs the same sound and / or voice. As another example, when the key data input in step S62 corresponds to an up key, the CPU 60 causes the sound reproducing unit 20 to correspond to audio data of voices of two speakers from the memory 10. The voice signal of any one of the voice signals is muted (step S68). Accordingly, the sound reproducing unit 20 can practice responding to the output voice.

The key data input in steps S58 through S62 do not correspond to any of the specific keys (for example, a fast forward key, a reverse key, or an uplink key), or the user index code is set to "0" in step S56. If it is determined that the audio information file being reset and being reproduced contains music information other than language learning information, or the audio information file is not being played back in step S52, the CPU 60 functions corresponding to the input key data. In operation S70, at least one of the memory 10, the sound reproducing unit 20, the display unit 40, and the relay unit 50 is driven to perform this operation. After the execution of any one of the steps S64 to S70, the CPU 60 returns to the step S50.

The control method of the portable audio player performed by the CPU 60 as described above allows the key data for some of the keys on the key input unit 30 to be recognized as specifying different functions according to the key mode. Accordingly, each of some of the keys on the key input unit 30 enables selection of at least two different functions. As a result, the control method of the portable audio player according to the embodiment of the present invention may enable selection of more functions than the number of keys by a limited number of keys. In addition, without a separate key, the control method of the portable audio player according to an embodiment of the present invention enables selective control of additional functions dedicated to language.
