Description

MP3 Audio for Cars {MP3 AUDIO SYSTEM IN VEHICLE}

The present invention relates to a vehicle MP3 (MP3) device, and more particularly to a vehicle MP3 audio that can easily search and manipulate the MP3 file contained in the CD-ROM with the vehicle MP3 player.

In general, MP3 is an acronym for MPEG 1 LAYER 3, and it is a standard technology that maintains CD-Quality sound quality while compressing data at a compression ratio of about 1:12 compared to digital audio data of conventional AUDIO CD. As it is small, it is easy to download from the Internet, and it can be used like a personal jukebox because it can store about 170 songs using a medium such as a 650MB CD-R / RW.

Thus, unlike conventional audio CDs or CD-ROM CDs, which are manufactured through a “pressing” process at specialized factories, ordinary users can use the “CD-R” writer or “CD-RW” writer on their PC. Data stored in the hard disk can be recorded by CD-R / CD-RW.

CD-R is an abbreviation of “Recordable” and can be recorded only once. CD-RW is an abbreviation of “Rewritalbe” and can be repeatedly recorded and deleted several times.

In other words, “MP3-CD” refers to the state where the user converts the AUDIO CD that is downloaded from the Internet or stored in the CD-R / CD-RW into the MP3 file. It can be played on a portable player “MP-JUKE” or a car “In-dash type Car-MP3 CD”, allowing users to select and edit their favorite music for more than 10 hours. It's a breakthrough.

However, the conventional MP3 device uses an expensive flash memory, but can store only 8 to 16 songs (64MB), and if the song is added beyond the memory capacity, the existing song must be deleted. It has a very troublesome problem of having to download songs in connection with PC.

Accordingly, an object of the present invention is to solve the above problems, and to provide an MP3 audio for a vehicle that can be searched and played by converting a song data file recorded on a CD-ROM into an MP3 file with an MP3 player.

The present invention for achieving the above object,

The CD type MP3 mode can be selected and the selected mode can be changed sequentially, and all MP3 files stored in the CD-ROM are played for a predetermined time, and the files are sequentially played from the currently playing file. In-car MP3 audio, which allows users to select and release songs stored in memory, release stored data, play and save songs stored in memory, and switch to sequential mode. In the present invention, CD-ROM data consisting of a plurality of sub folders under a boot is reconfigured and recognized as MP3 data consisting of one sub folder under one boot.

1 is a perspective view of a vehicle MP 3 audio configuration applied to the present invention.

2 is a data folder structure of MP3 audio for a vehicle applied to the present invention.

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

FIG. 1 is a MP3 audio for automobiles according to the present invention, when the user inserts CD-ROM data in which a song data is recorded, which is mounted in a vehicle, the vehicle MP3 audio is corresponding to the user's button selection. Performs the function of.

Therefore, in the MP3 apparatus, the power supply unit 10 applies power to the MP3 audio for the vehicle according to the user's selection. The display unit 20 displays an initial screen and a title of data selected by the user. The mode selector 30 is used when the CD type MP3 mode is selected, and the mode can be changed in the order of AM-CD-FM, and the MP3 and CD data are automatically recognized when the CD is initially inserted. The search unit 40 sequentially plays all MP3 files stored in the CD-ROM from the file currently being played to the last file for a predetermined time. The memory setting unit 50 simultaneously stores and displays the song selected by the user in the memory, and plays and releases the stored content according to the user's selection. The forward / backward search unit 60 performs forward / backward search and playback within the data of the song being played according to the user's will. The list forward / reverse search unit 70 sequentially searches the MP3 file list stored in the CD-ROM, and displays a portion without the MP3 list as “no file”. The repeat playback unit 80 switches all MP3 files in the current folder to repeat play and sequential mode, and continuously plays back the currently played file according to the user's selection. The random unit 90 reproduces the MP3 file stored in the CD-ROM in a random order and switches to the sequential mode. The key knob 100 can easily navigate the data of the CD-ROM according to the user's up / down / left / right operation. In particular, the key knob 100 can move to the upper / lower folder from the current folder position. Makes next song and all songs searchable.

Accordingly, in the vehicle MP3 device having each of the function keys as described above, when the user inserts the CD-ROM, the CD-sub consists of several subfolders based on booting, as shown in FIG. 2. The ROM data is switched to the MP3 data state having one subfolder on the basis of the boot, and the title data recorded in each subfolder is searched and stored in the memory.

Subsequently, when a corresponding button manipulation for the user's search is made, the MP3 device displays the title sequentially for a predetermined time (about 10 sec) on the basis of the data currently being played and reproduces it so that the user can listen to it.

Then, the data of the song currently being played may be temporarily stored in the memory and the stored data may be deleted, and may be repeatedly played until another user's selection is made.

This simplifies the user's operation of the corresponding button, simplifying its use, and at the same time enabling a quick search when searching for the corresponding data.

As described above, the vehicle MP3 apparatus according to the present invention can search and play song data files stored on CD-ROMs as MP3 files using MP3 players, thereby simplifying the user's operation of the corresponding button. At the same time, there is an effect that quick search is possible when searching the data.
