By constructing a car audio system with an output means, it is possible to provide a multi-functional car audio device that can provide a variety of active functions such as high-quality sound such as a compact disc, update of music files, use of karaoke, and voice recording. It is about.

Description

Multi Function Car Audio Device

The present invention relates to an audio system of a vehicle. In particular, an MP3 player and a sound card are installed in a car audio to utilize all the music functions used in a computer, and a car that can arbitrarily listen to a large amount of songs at a high quality such as a compact disc. Relates to an audio device.

In general, a car audio system is composed of a radio, a tape player and a compact disc player, and tunes a specific broadcast frequency channel by radio to listen to a desired broadcast or to store music stored on a predetermined recording medium through a tape player or a compact disc player. Play and listen.

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

1 is a diagram illustrating a car audio device according to an embodiment of the present invention, which includes an MP3 player 10, a sound card 15, and a speaker 20.

The MP3 player 10 may store a plurality of songs, and may select a memory 11 capable of downloading an arbitrary music file from the outside and a command for selecting a song stored in the memory 11 and performing a predetermined function. An input unit 12, an output unit 13 for converting and amplifying the song data stored in the memory 11 into a predetermined signal form, and a control unit 14 for controlling the operation of the various devices 11 to 13; It is.

In addition, the sound card 15 may perform various types of voice processing functions, such as recording and restoring voice, and is configured to convert the song data output from the memory 11 into an analog signal and then amplify the speaker. 20 is configured to convert an electrical voice signal output from the sound card 15 into a vibration signal and output the vibration signal.

The audio system of the present invention is connected to the music file of the portable computer such as the memory 11 of the MP3 player 10 and the notebook PC 25, and can download various songs from the PC 25 at any time. Among the songs desired by the driver, the player may select and listen to the key input unit 12 of the player 10.

In addition, by connecting a microphone 30 to the sound card 15, the audio system can be utilized as a karaoke function, and if a crisis situation occurs while driving, the MP3 player 10 is recorded through the key input unit 12. After operating, the driver's voice may be recorded through the microphone 30.

In addition, by selecting a specific sound among various digital sounds stored in the memory 11 through the key input unit 12 of the MP3 player 10 and setting it as the horn sound of the vehicle, the horn sound of the vehicle can be freely changed by the driver.

By downloading the computer music files as well as tapes and compact discs to the MP3 player using car audio as described above, only the desired songs can be stored in the memory and listened freely. You can use various functions in the car, such as listening to a microphone, using a karaoke function, or recording a driver's voice in a crisis situation.

As described above, in the present invention, an audio system is constructed using an MP3 player and a sound card, thereby providing a variety of active functions such as updating high quality sound and music files such as a compact disc, using karaoke, and recording a voice. do.
