Summary: | PURPOSE: A vehicle handsfree system is provided to connect a handsfree device to a car audio system so that a user can make a call using a portable phone through a microphone and the speaker of the car audio system in the middle of driving, without the necessity of purchasing and installing special sales goods or without doing damage to the inside of a vehicle. CONSTITUTION: A vehicle handsfree system is comprised of a microphone(28), a portable phone access part(32), an earphone output part(29), a call button part(30), and a handsfree control part(31). The microphone(28) converts a driver's voice signal into an electrical signal. The portable phone access part(32), connected with an earphone jack(33), transmits and receives a call signal and a control signal. The earphone output part(29) outputs a voice signal through an earphone(36) in a secret call. The call button part(30) is to select a generic call or a secret call and to operate various functions. The handsfree control part(31) outputs a control signal, dependent on the state of the call button part(30), and a voice signal, inputted through the microphone(28), to a portable phone(34) through the portable phone access part(32). In a secret call, the handsfree control part(31) outputs a call signal, inputted through the portable phone access part(32), only to the earphone output part(29).
본 발명은 차량용 핸즈프리 장치에 관한 것으로서, 운전 중 휴대폰의 통화를 위해 사용되는 핸즈프리 장치를 카오디오에 결합시킴으로써 별매품을 구매하여 장착하거나 차량내부의 손상을 주지 않고도 마이크와 카오디오의 스피커를 통해 운전 중 휴대폰을 이용한 통화를 할 수 있도록 할 뿐만 아니라 전화통화 음질은 카오디오의 기능에 따라 볼륨을 조절하거나 음색을 조절함으로써 상대방을 음성을 명확하게 들을 수 있는 이점이 있다. |
