Description

무선송신기를 갖춘 차량용 CD플레이어 {CAR CD PLAYER THAT HAS FM MODULATION TRANSMITTER}Car CD Player with Wireless Transmitter {CAR CD PLAYER THAT HAS FM MODULATION TRANSMITTER}

본 고안은 차량에 탑재된 CD플레이어의 오디오 신호(AUDIO SIGNAL)와 차량에 탑재한 핸드폰의 수신신호를 FM 무선 변조기를 통하여 방송 수신 대역으로 무선송신하므로서, 이 신호로 차량에 탑재된 카 스테레오(CAR STERO)로 수신하므로서 CD 음악과 핸드폰 수신을 카 스테레오로 통하여 크게 증폭하여 청취할 수 있음과 동시에 차량용 전원 DC 12V를 정전압 안정시킬 수 있는 무선 송신기를 갖춘 차량용 CD 플레이어에 관한 것이다.The present invention wirelessly transmits an audio signal (AUDIO SIGNAL) of a CD player mounted on a vehicle and a mobile phone signal received in a vehicle to a broadcast reception band through an FM radio modulator. The present invention relates to a car CD player equipped with a wireless transmitter capable of amplifying and stabilizing a DC 12V power supply of a car while simultaneously receiving CD music and cellular phone reception through a car stereo by receiving it through a STERO).

종래에는 차량용 CD 플레이어 받침대로서 그 내부에 정전압 안정기로 갖춘 장치가 있었으나, 이를 사용하기 위하여 CD 플레이어의 오디오 신호를 카 스테레오와 차폐선(SHIELD WINE)로서, 유선으로 결합하는 번거로움이 있을 뿐 아니라, 핸드폰 수신 신호는 카 스테레오로서 증폭 시킬 수 없는 결함이 있었던 것이다.Conventionally, there was a device equipped with a constant voltage stabilizer therein as a vehicle CD player stand, but in order to use this, as well as the audio signal of the CD player as a car stereo and a shield line (SHIELD WINE), there is a hassle of combining wires, Cell phone reception was a car stereo fault that could not be amplified.

본 고안은 CD 플레이어에서 나오는 오디오 신호와 핸드폰의 수신 신호를 FM 방송대역으로 무선변조 시키므로서 차량에 탑재된 카 스테레오를 통하여 증폭시켜 들을 수 있는 것을 제공함에 그 목적이 있는 것이다.The present invention aims to provide an amplified audio signal from a CD player and a cellular phone received by amplifying through a car stereo mounted on a vehicle by wirelessly modulating the FM broadcast band.

도 1은 본 고안의 보록다이아그램.1 is a borok diagram of the present invention.

상기 목적을 달성하기 위한 본 고안을 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.The present invention for achieving the above object is described in detail with reference to the accompanying drawings.

차량용 전원 DC 12V는 정전압 안정기 3에 연결되고 출력전압 3V, 4.5V, 6V, 9V는 SW1을 통하여 CD 플레이어 4에 연결되고, 이의 출력 AF는 SW2를 통하여 FM 변조기 1에 연결되며, 변조기에는 ANT가 연결되어 있다. 한편 핸드폰 5의 수신 신호는 SW2에 연결되어 있다.Vehicle power DC 12V is connected to constant voltage stabilizer 3, output voltages 3V, 4.5V, 6V, 9V are connected to CD player 4 via SW1, its output AF is connected to FM modulator 1 via SW2, and ANT It is connected. On the other hand, the received signal of mobile phone 5 is connected to SW2.

카 레디오 2에는 ANT가 연결되고, 그 출력은 SP에 연결되도록 구성된 것이다.Car Radio 2 has an ANT connected and its output configured to connect to the SP.

상기와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

차량 전원 DC 12V는 전압 안정기 3에서 3V, 4.5V, 6V, 9V로서 안정된다.The vehicle power supply DC 12V is stabilized as 3V, 4.5V, 6V, 9V in voltage stabilizer 3.

CD 플레이어 4에서 필요한 전압에 따라서 SW1으로서 전압을 선택할 수 있는 것이다. CD 플레이어가 작동하면 오디오 신호(AF SIGNAL)는 스윗치 SW2의 선택에 의해 FM 변조기 1에 연결되며, 이 FM 변조기는 CD의 신호를 방송 수신 주파수로 송신한다.The voltage can be selected as SW1 according to the voltage required by the CD player 4. When the CD player is activated, the audio signal AF SIGNAL is connected to FM modulator 1 by selection of switch SW2, which transmits the signal of the CD at the broadcast reception frequency.

한편, 차량 내에 장착된 카 스테레오는 이 FM 변조 된 신호를 레디오(RADIO)로 수신하여 그 출력을 카 스피커로서 소리를 발생시킨다.On the other hand, the car stereo mounted in the vehicle receives this FM modulated signal to RADIO and generates the output as a car speaker.

한편, 핸드폰 5로서 수신된 신호는 RX SIG 단자로 통하여 SW2에 연결되며, 이는 FM 변조기 1을 통하여 FM 방송대역으로 변조되어 송신이 된다. 이 송신 신호는 카 레디오 2에서 수신되어 스피커 SP로 통하여 소리를 발생한다.On the other hand, the signal received as the mobile phone 5 is connected to SW2 through the RX SIG terminal, which is modulated into the FM broadcast band through the FM modulator 1 and transmitted. This transmitted signal is received at cardio 2 and generates sound through the speaker SP.

한편, 차량 내부에 부착된 마이크 MIC를 통하여 음성신호는 핸드폰 5에 연결된다.On the other hand, the voice signal is connected to the mobile phone 5 through the microphone MIC attached to the inside of the vehicle.

이상과 같이 본 고안으로 된 장치를 통하여 차량 탑재용 CD의 음악을 FM 변조기 1로서 무선송신하여 카 레디오로서 크게 증폭하여 들을 수 있고 핸드폰을 통하여 통신할 경우 핸드폰 수신 신호를 FM 변조기 1로서 무선 송신하여 카 레디오로서 증폭하여 들을 수 있으므로 핸드푸리(HAND FREE)의 기능을 할 수 있도록 하는 효과를 지닌 것이다.As described above, the music of the vehicle-mounted CD can be wirelessly transmitted as the FM modulator 1 through the device of the present invention to greatly amplify and listen to the car radio. As it can be amplified and listened to as a car radio, it has the effect of functioning as a hand free.
