    How to play audio signal of CD
    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio system. In particular, a CD (Compact Disc: hereinafter referred to as a CD) in an audio system is intro-played to selectively designate a track on which a user desired song is recorded and stored in a memory. When the play key is selected, the present invention relates to a method of reproducing an audio signal of a CD, which sequentially reproduces only the songs recorded in the track stored in the memory.
    Referring to an operation for playing a cassette tape in a general audio system, after turning on the power of the audio system, a user inserts a cassette tape into a deck.
    Then, after selecting a tape function among the functions of the audio system and pressing the play key, the inserted tape is played. At this time, when the position of the inserted cassette tape is not the first part but the middle part, it is played according to the user's selection. When the user wants to play the cassette tape from the current position, the user presses the play button immediately to play it. If you want to play back, select the rewind mode, that is, select the Rewind key to rewind the tape for the first time.
    When the rewind operation is completed to the first position of the cassette tape, the rewind mode is switched to the stop mode and the rewind operation is stopped. When rewind is stopped, the user selects the play key again to play the cassette tape from the beginning.
    In order to play a CD, first, a CD function key is selected, and then, when a play key is selected, audio data recorded on the CD is played. Here, reproduction of the audio signal recorded on the CD is performed by using a pick up device.
    When playing a CD using the pickup apparatus, the pickup apparatus reads the number of tracks of the CD, that is, the number of songs and the playing time of each song, and stores the number of tracks and the playing time of the songs recorded on each track in the memory. Will be
    Subsequently, in order to play the intermediate songs among the plurality of songs recorded on the CD, the user knows all the songs recorded on the CD, and then designates the track on which the track to be played is recorded by using the track assign key and then plays the track. When the key is selected, the pickup device is moved to the first position of the selected track to play the audio signal recorded on the track.
    However, in the audio signal reproduction method of a CD according to the related art, in order to reproduce only an audio signal of a part of audio signals recorded on a CD, that is, songs in the middle of a plurality of songs, a song to be reproduced using a track designation key is used. If you select the recorded track and then select the play key, only the audio signal of the designated track is played. In addition, after all the songs of the specified track are played, in order to play a song recorded on another track, the CD deck is stopped, the desired track is designated again, and the play key is pressed to play the track. will be,
    Therefore, in order to selectively play a desired song, there is a problem that the track designation and the stop keys of the CD deck are repeatedly used as described above, and there is a problem in that the desired song cannot be continuously played at once.
    In addition, in order to reproduce a desired song in this way, the user must know what song is recorded in each track.
    The present invention has been made to solve the above-mentioned problems according to the prior art, the object of the present invention is to play the intro (Intro) function of the CD, that is, to play only the beginning of all the songs recorded on the CD for a certain time Using the function to selectively select the track to be recorded among the songs to be played in the memory to store in the memory, and according to the input of the playback key to play all the songs recorded in the track stored in the memory sequentially The present invention provides a method for reproducing an audio signal of a CD.

    The audio signal reproducing method of the CD according to the present invention for achieving the above object is a CD audio signal reproducing method of an audio system having a pickup device, a memory, an intro play key and a storage key. Performing an intro reproducing operation of reproducing the audio signal of the initial portion of each track while sequentially moving each track of the CD according to the intro reproducing input signal of a key; If the storage key input signal is applied during intro playback, storing a track number in which the audio signal currently intro reproduced is recorded in the memory; When the storage is completed, driving the pickup device to perform an intro playback operation from the track after the stored track; When the intro playback operation is completed, canceling the intro playback mode to stop the drive of the CD deck; When the play key input signal is applied, the pickup device is driven to sequentially play the audio signals recorded in each track in the order of the track number stored in the memory.
    Hereinafter, an embodiment of an audio signal reproduction method of a CD according to the present invention will be described with reference to the accompanying drawings.
    1 is a block diagram of an apparatus for implementing an audio signal reproducing method of a CD according to the present invention. Referring to FIG. 1, a block configuration of a key input unit 10, a control unit 11, and a CD are shown. It consists of the deck 12 and the memory 13.
    The key input unit 10 includes an intro play key, a storage key, and a play key to provide the controller 11 with an intro play signal for sequentially playing the initial portions of all the songs recorded on the CD for a predetermined time, and intro play. When a song to be recorded by the user is reproduced, a storage key input signal for storing the track number in which the song is recorded in the memory 13 is provided to the controller 11. In addition, the controller 11 applies a playback key input signal for sequentially reproducing the songs recorded in each stored track while all track numbers recorded by the user are to be reproduced.
    When the intro play key signal of the key input unit 10 is applied, the control unit 11 controls the pickup device of the CD deck 12 to reproduce the audio signal of the initial part of the songs recorded on each CD track for a predetermined time. In addition, when the storage key input signal is applied during the intro playback, the corresponding track number in which the track currently being played is recorded is stored in the memory 13.
    In addition, the control unit 11 picks up the CD deck 12 when the play key input signal is input in the stored state in which all the track numbers on which the desired songs are recorded are stored in the memory 13, that is, the intro playback is completed. The device is controlled to sequentially play the tracks recorded in each track while sequentially moving corresponding tracks of the CD according to the track numbers stored in the memory 13.
    As a result, only the songs recorded in the track stored in the memory 13 are reproduced sequentially.
    A method of reproducing an audio signal of a CD corresponding to an operation of an apparatus for implementing an audio signal reproducing method of a CD according to the present invention having the configuration as described above will be described with reference to FIGS. 1 and 2.
    2 is a flowchart illustrating an operation of a method of reproducing an audio signal of a CD according to the present invention.
    First, after turning on the power of the audio system (S101), a CD to be played is inserted into the CD deck 12 (S102).
    Subsequently, it is determined whether the intro reproduction key signal has been input (S103). If the intro reproduction key signal is input, the intro reproduction operation is performed (S104). Here, the intro reproducing operation is a function of reproducing only the beginning of all the songs recorded on the CD for a predetermined time as described above. In order to perform this intro playback operation, the control unit 11 moves the pickup device of the CD deck 12 to each track, that is, moves the pickup device to the first track so that only a portion of the beginning of the song recorded on the first track is moved. After a certain portion has been played back, the pickup unit is moved back to the second track so that only a portion of the beginning of the track recorded on the second track is played. will be.
    In this way, when the user hears the audio signal played during the intro playback of the CD and the desired song is played, the storage key is selected to store the song in the memory 13. That is, it is determined whether the storage key is input during intro playback (S105), and when the storage key is input, the controller 11 stores the corresponding track number of the song currently being played in the memory 13 (S106).
    Subsequently, it is determined whether or not the corresponding track number is stored in the memory 13 (S107). When the storing is completed, the controller returns to the intro mode and performs the intro playback operation from the track after the stored track (S108).
    It is determined whether a storage key is input during intro playback (S109). If a song desired by the user is played intro and the storage key is input, the feedback is fed back to step S106 to store the corresponding track number in the memory 13, and the storage key is not input. If not, it is determined whether all the intro playback of the CD is completed (S110).
    If it is determined that the intro play is completed, the intro play mode is canceled. That is, the drive of the CD deck 12 is stopped (S111).
    Subsequently, it is determined whether the play key is input in a state in which the corresponding track numbers for the image are all stored (S112).
    In other words, storing the track number of the tracks desired by the user in the memory 13 in this way is to continuously play only the tracks desired for playing the CD. If input, the control unit 11 controls the pickup device of the CD deck 12 to sequentially play the songs recorded in each track in the order of the corresponding track storage stored in the memory 13 (S113).
    As a result, the audio signal reproducing apparatus of the CD according to the present invention selects a storage key to store the corresponding track number in the memory 13 when the music to be recorded by the user is reproduced during the intro reproduction operation of the CD as described above. do. In this manner, only the tracks recorded in the track stored in the memory are sequentially played according to the input of the playback key while all the track numbers of the desired tracks among the plurality of tracks recorded on the CD are stored.
    As described above, the apparatus for reproducing an audio signal of a CD according to the present invention selects a storage key and stores a corresponding track number in a memory when a song to be recorded by a user is played intro during the intro playback operation of the CD. In this way, while all the track numbers of the desired songs among the plurality of songs recorded on the CD are stored, only the songs recorded in the track stored in the memory are sequentially played according to the input of the playback key. There is an advantage that only the desired songs among the plurality of songs recorded on the CD can be sequentially listened to and listened without a separate key operation. In addition, there is an advantage that the user does not need to know all the songs recorded on the CD one by one.
