본 고안은 무선전화기의 통화대기 장치에 관한 것이다.The present invention relates to a call waiting apparatus for a wireless telephone.

주지된 바와 같이 통화를 하던 중 급한 용무가 있든지, 또한 특정인을 바꾸고자 할 때는 통화상태로 대기를 하여야 하는데, 이때 송화자는 지루함을 느끼게 마련이다.As is well known, when there is an emergency during a call or when you want to change a specific person, you have to wait in a call state, and the caller will feel bored.

따라서 송화자에게 지루함을 느끼지 않게 하려는 통화대기 장치가 이미 개발되어 사용되고 있는데, 이와같은 종전 장치중 대표적인 것으로는 오르겔을 이용한 기계적 장치 또는 음악을 발생하는 전자적 장치등을 들수 있으나, 기계적 장치는 태엽을 동력원으로 하는 것이므로 수시로 태엽을 감아 주어야 하는 불편이 있고, 전자적 장치는 전화기에 부착하여야 하는 것이어서 값이 비싸며, 특히 이들장치는 모두 통화대기시 마다 일일이 조작하여야 하는 번거로움이 있었다.Therefore, a call waiting device has been developed and used so as not to be bored by the caller. Among the previous devices, such as a mechanical device using an orgel or an electronic device that generates music, the mechanical device is a mainspring as a power source. It is inconvenient to wind up the springs from time to time, and the electronic devices are expensive to attach to the phone, especially these devices all had a hassle to operate every call waiting.

또한 음향을 발생하는 멜로디 회로를 전화기 고정장치내에 설치하므로서, 그 조작이 오로지 고정장치에만 연관되어 동작이 가능하였다.In addition, by installing a melody circuit that generates sound in the telephone fixture, the operation was possible only in connection with the fixture.

즉, 무선전화기의 장점은 야외에서 즉 먼거리에서도 통화가 가능하다는 점인데, 야외에서 사용시는 음향을 발생하는 멜로디를 동작시키려면 고정장치까지 이동해야 하는 번거로움이 발생하였다.In other words, the advantage of the wireless phone is that it is possible to talk in the outdoors, that is, from a long distance, the use of the outdoor when the melody to generate a sound has to move to a fixed device to operate.

본 고안의 목적은 이동장치에 멜로디 회로를 설치하여 어느 장소에서 통화를 해도 멜로디 동작이 가능하고, 아울러 통화대기시마다 일일이 조작을 하지 않고, 다만 이동장치를 책상위에 내려 놓으면 멜로디 회로가 동작되는 장점이 있다.The purpose of the present invention is to install a melody circuit in the mobile device, which makes it possible to operate the melody in any place, and also do not operate each time during the call waiting, but if the mobile device is placed on the desk, the melody circuit operates have.

이하 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다. 본 고안의 장치는 이동장치(50)에 설치되는 것으로 기존 이동장치내부의 송신회로(5)와 변조회로(6) 및 송화기앰프(7)에 설치되는 것으로 제1도와 같이 구성된다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The device of the present invention is installed in the mobile device 50 and is installed in the transmission circuit 5, the modulation circuit 6, and the transmitter amplifier 7 in the existing mobile device.

즉 이동장치 내부에 멜로디IC(9)와 멜로디 스위치(4)를 설치하되, 멜로디스위치(4)는 제2도와 같이 이동장치 외부로 돌출되게 설치한다.That is, the melody IC 9 and the melody switch 4 are installed inside the moving device, but the melody switch 4 is installed to protrude out of the moving device as shown in FIG.

또한 내장된 전원(8)의 한 선은 멜로디 IC(9)에 직접 공급되고, 다른 선은 트랜지스터 Q1의 에미터와 그리고 저항 R1, R3및 멜로디스위치(4)와 콘덴서 CI를 통해 송화기 앰프(7)에 연결되어 있다.In addition, one line of the built-in power supply 8 is directly supplied to the melody IC 9, and the other wire is connected to the emitter of transistor Q 1 and the resistors R 1 , R 3 and the melody switch 4 and the condenser CI through the transmitter. It is connected to the amplifier (7).

그리고 트랜지스터 Q1의 베이스는 저항 R2로서, R1에 연결되어 있고, 콜랙터는 멜로디 IC(9)와 연결되어 있다.The base of the transistor Q 1 is a resistor R 2 , which is connected to R 1 , and the collector is connected to the melody IC 9.

이와같이 구성된 본 고안은 이동장치(50)를 들고 통화를 할 때는 멜로디스위치(4)는 접점(B)(C)가 (A)(D)에 접속되지 못하고, 이동장치 제3도 처럼 지면에 내려놓으면 튀어 나온 멜로디스위치(4)가 눌려저서 접점(B)(C)는 (A)(D)와 접속되어 그라운드 되도록 되어 있다.The present invention configured as described above, when making a call with the mobile device 50, the melody switch 4 is not connected to the contact point (B) (C) (A) (D), the mobile device is lowered to the ground as shown in FIG. When released, the melody switch 4 protrudes and is pressed, so that the contacts B and C are connected to ground and connected to (A) and D.

통화가 시작되면 전원(8)은 멜로디스위치(4)가 그라운드 되지 못하므로 저항 R1과 R3및 콘덴서 C1을 통해 마이크앰프(7)에 공급되므로, 음성신호는 마이크앰프(7)를 구동시켜 변조회로(6)에서 변조되어 송신회로(5)를 통하여 상대방에게 도달되어 통화가 이루어진다.Since the melody switch 4 is not grounded when the call is started, the power supply 8 is supplied to the microphone amplifier 7 through the resistors R 1 and R 3 and the condenser C 1 , so that the voice signal drives the microphone amplifier 7. The call is modulated by the modulation circuit 6 to reach the other party through the transmission circuit 5 to make a call.

이 상태에서 필요에 따라 통화상태로 대기할 경우에는 사용자는 이동장치를 지면에 내려놓으면 멜로디스위치(4)는 제3도와 같이 눌려져서 접점(B)(C)는 (A)(D)와 접속된다.In this state, if the user waits in a call state as necessary, when the user puts the mobile device on the ground, the melody switch 4 is pressed as shown in Fig. 3 so that the contacts B and C are connected to the A and D. do.

이때 저항 R1, R3로 흐르던 전류는 접점(C)(D)로서 그라운드되므로, 트랜지스터 Q1의 베이스 전위는 낮아지게 되어 트랜지스터 Q1이 턴온된다.The resistor R 1, the current flowing in R 3 are so ground as a contact point (C) (D), the base potential of the transistor Q 1 is lowered the transistor Q 1 is turned on.

그러면 멜로디 발생IC(9)에 전원이 공급되어 멜로디 IC(9)는 동작이 되며, 그 출력은 변조회로(6)와 송신회로(5)를 통하여 상대방에게 전달된다.Then, power is supplied to the melody generating IC 9 so that the melody IC 9 is operated, and its output is transmitted to the counterpart through the modulation circuit 6 and the transmitting circuit 5.

아울러 마이크앰프(7)의 공급되는 전위도 낮아지므로 음성출력은 상대방에게 도달되지 못한다.In addition, since the potential supplied to the microphone amplifier 7 is also lowered, the audio output cannot be reached.

이상과 같이 본 고안은 통화대기시 수동으로 일일이 조작할 필요가 없이 이동장치를 지면에 내려 놓기만 하면 자동으로 멜로디가 발생되는 특징이 있는 통화대기 장치인 것이다.As described above, the present invention is a call waiting device having a feature of automatically generating a melody by simply dropping the mobile device on the ground without manually manipulating the call waiting.
