Description

Hand-free apparatus of moving communication terminal using car audio}

The present invention attaches a mobile communication terminal to a control panel that is detachably attached to the car audio and controls the operation of the car audio, charges power to the battery of the mobile communication terminal, makes a phone call hands-free, as well as in the mobile communication terminal. The present invention relates to a hands-free device of a mobile communication terminal using car audio for listening to a reproduced voice signal of an output MP3 through car audio.

In general, the vehicle is equipped with a car audio to enable the driver and passengers of the vehicle to drive and ride the vehicle in a more comfortable state. The car audio is provided with an AM / FM radio, tape player and / or CD / MD player integrally, and selectively operates the AM / FM radio, tape player and / or CD / MD player according to the user's operation. It is possible to listen to broadcast signals or to listen to playback signals of playback media such as tape cassettes, CDs and / or MDs. Such car audio is very expensive and frequently intruders are stolen by separating an intruder and car audio when the vehicle is parked.

Therefore, in recent years, the control panel of the car audio is manufactured to be detachable from the front of the car audio, and when the vehicle is parked, the control panel is detached from the car audio to prevent carrying and theft of the car audio. The control panel is attached to the front of the car audio, and the control panel controls the operation of the car audio according to the user's operation.

On the other hand, with the development of information and communication technology, changes in life styles and economic growth, the form of communication culture is changing rapidly, and in the information age, the demand for high-speed information transmission, as well as time, underground, air, sea and mountain areas Mobile communication systems that can receive communication services regardless of the place of the back, are becoming an important communication medium indispensable in daily life.
