Abstract

본 발명은 셀룰라폰의 핸드프리키트에 관한것으로, 핸드프리키트에 유선으로 인터페이스된 외부마이크로폰을 무선마이크로폰 시스템으로 구현하여 변조 및 송신할 수 있도록 하고 핸드프리키트에서 무선마이크로폰 시스템으로부터의 송신신호를 수신 및 복조하여 핸드프리키트를 운용함으로써 무선 마이크로폰을 사용자가 옷깃 등에 꽂아 사용할 수 있으므로 마이크로폰에서 멀리 위치한 사용자도 편리하게 통화할 수 있다.The present invention relates to a handfree kit of a cellular phone. The external microphone interfaced to the handfree kit by wire can be implemented by a wireless microphone system to allow modulation and transmission, and to receive a transmission signal from the wireless microphone system in the hand free kit. And by demodulating and operating the hand-free kit, the wireless microphone can be plugged into the user's collar, etc., so that a user far from the microphone can conveniently talk.
