The USB module 120 reads and reproduces data stored in a USB (Universal Serial Bus) external memory, and the Bluetooth module 130 Receives and reproduces data transmitted from a device (e.g., a smart phone) connected via Bluetooth, and the radio module 140 receives and reproduces radio signals such as AM and FM.

The Global Positioning System (GPS) module 150 is used to receive a GPS signal and detect the current position of the vehicle.

The sound source data management unit 160 controls the disc module 110, the USB module 120, the Bluetooth audio module 130, the radio module 140, and the GPS module 150 to generate data The number of times of music reproduction, the cumulative time of music reproduction, the current position, the preference, etc.), manages music data on the basis of the collected data, and reproduces corresponding music according to a user's instruction.

The sound source data management unit 160 functions as a control unit for music reproduction.

In the present embodiment, the sound source data management unit 160 assigns weights to music frequently heard by the user (that is, music with high preference) and stores the music in a database (see FIG. 3) And instructs the music player to randomly reproduce the music).

FIG. 3 is an example of a database generated in FIG. 2 for analyzing a music preference of a user.

As shown in FIG. 3, the database stores the number of songs, albums, song names, sound source information (e.g., about 5 seconds of data of sound source data being played back), accumulated playback time, location information, (E.g., the number of times the same music is repeatedly reproduced during movement of a specific location or route).

2, the UI display unit 170 displays data related to music to be played according to the control of the sound source data management unit 160, receives a command related to music playback from the user, Information related to mood or music preference (for example, volume control, button input, location information, etc.).

For example, the UI display unit 170 can process both the output of music playback information and the input of information related to music playback.

The sound output unit 180 converts the selected music into an analog signal under the control of the sound source data management unit 160 and outputs the converted analog signal through the speaker 190.

4 is a flowchart illustrating a method of playing music in a multimedia device for a vehicle according to an embodiment of the present invention.

As shown in FIG. 4, the sound source data management unit 160 assumes a state in which music is being reproduced in the vehicle multimedia device according to the present embodiment (S101).

The sound source data management unit 160 may generate a play list for the music playback and may scan the MP3 music files stored in the memory (internal memory or external memory) and sequentially play or randomly play the music without creating a play list .

However, in the present embodiment, the description of the simple random reproduction or the sequential reproduction will be omitted, and a music reproduction method based on the reproduction list reflecting the user's propensity or preference will be mainly described.

The sound source data management unit 160 detects information related to the music preference of the user during the music reproduction (S102).

Information related to the music preference may be detected in the playlist (e.g., by adjusting the list rank by the user) or detected during music playback (e.g., by selecting a preference button displayed on the screen, Manipulation, etc.). Information related to the music preference can be detected even during simple random playback or sequential playback.

When the information related to the musical tendency or preference of the user is detected as described above, the tone generator data management unit 160 generates a database for analyzing the user's musical preference (S103).

When the continuous detection of the information related to the preferences and the random playback function reflecting the preference in the state where the database is generated are performed as described above (S104), the sound source data management unit 160 stores information (for example, Location, current time, music preference of the user, etc.) (S105) (see Fig. 5).

FIG. 5 is a view showing an example of a playlist screen for music reproduction of a multimedia device for a vehicle according to an embodiment of the present invention, and includes artist, song, album, , And is arranged in descending order of score according to the preference score set for each piece of music (i.e., music name).

The user selects one of the songs (music) in the playlist and changes the priority. As the priority is changed as described above, the preference score of the song is changed according to the ranking.

6). When a user inputs a preference up button (e.g., a Good button), the preference degree (favorite score) of the currently reproduced music is increased and the user decreases the preference degree If you enter a button (eg Not Good button), the preference (favorite score) of the currently playing song will decrease. At this time, depending on the number of times the button is pressed, the preference score may be higher or lower.

In addition, if the driver changes to the next music during music playback, the time to reproduce the music is sensed and the preference score is different according to the reproduction time. In addition, the same music can be repeatedly played back repeatedly. At this time, the number of times of reproduction and the total reproduction time are accumulated and a preference score is charged differently.

In addition, if the volume is increased during music playback, the user's preference score increases for the song, and if the volume is lowered during music playback, the user's preference score decreases for the song. Using this principle, the sound source data management unit 160 automatically raises the volume when a song having a high user's preference is reproduced during the music random play, and automatically plays the volume by lowering the volume when the song having a low user's preference is reproduced.

In this case, the range of the volume to be automatically controlled can be limited, and the volume in which the volume is automatically adjusted can be set to a higher constant range.

The reproduction list is a reproduction list reflecting the user's propensity and preference, and the sound source data management unit 160 reproduces music according to the reproduction list (S106).

At this time, the driver does not have to listen to all music (music) set in the playlist, but can selectively listen to it by setting the number of songs (for example, 5 songs, 10 songs, 30 songs, etc.) That is, the user may randomly select and play music in the playlist generated by reflecting the music preference of the user.

In addition, the user may have different preferred music according to the vehicle traveling route.

For example, you can listen to music of a lively type (for example, dance, group sound, etc.) so that you can start a lively day by waking up in the morning on the way to the morning, and type in which you can smoothly wrap a tired day 7, the sound source data management unit 160 uses the information detected through the DSP module 150 to determine a current position (e.g., And acquires the route information set in the navigation module (not shown) to reproduce the music having a high preference score that matches the route and the position that are currently being traveled.

As described above, the preference score may vary depending on the situation of the playlist.

For example, a preference score of a playlist to be applied to a commute, a preference score of a playlist to be applied to a workout, and a preference score of a playlist to be applied to a normal playout may be different.

Accordingly, the user can reproduce the music through the differently combined play lists in various situations, so that the new music is always played without being bored during driving.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, I will understand the point. Accordingly, the technical scope of the present invention should be defined by the following claims.
