Listening can provide convenience to the user.

이하, 예시도면을 참조해서 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제 1도는 본 발명에 따른 전화기의 착신음량조절회로의 블록도를 나타낸 것으로, 동 도면의 회로중 참조부호 1은 통화대기상태임을 알리는 착신신호음을 발생시키는 착신신호발생부, 2는 착신신호출력부, 3은 착신신호제어부, 4는 상기 착신신호출력부(2)로부터 출력되는 착신신호를 상기 착신신호제어부(3)로부터의 제어전위에 따라 상기 착신신호음량을 소정의 레벨로 증폭시켜 출력하는 전위제어증폭부, 5는 착신신호증폭부 및, 6은 스피커를 각각 나타낸 것이다.1 is a block diagram of an incoming volume control circuit of a telephone according to the present invention. In the circuit of FIG. 1, a reference signal 1 is an incoming signal generator for generating an incoming call tone indicating a call waiting state, and 2 is an incoming signal output unit. 3 denotes an incoming signal control unit; and 4, an incoming signal output from the incoming signal output unit 2 is a potential for amplifying and outputting the incoming signal volume to a predetermined level according to the control potential from the incoming signal control unit 3; The control amplifier, 5 denotes an incoming signal amplifier, and 6 denotes a speaker.

여기서, 상기 착신신호제어부(3)는 착신신호출력부(2)로부터 출력되는 착신신호를 소정의 횟수(예컨대 5회)만큼 카운트하여 수신자가 전화를 받지 않을 경우에는 착신음레벨업카운터(B)를 증가시킴과 더불어 전위제어증폭부(4)에 소정의 제어전위를 송출함으로써 상기 전위제어증폭부(4)로 하여금 착신신호의 신호음량을 소정의 레벨만큼 증폭시켜 출력하게 한다.Here, the incoming signal control unit 3 counts the incoming signal output from the incoming signal output unit 2 for a predetermined number of times (for example, five times), and when the called party does not answer the call, sets the incoming sound level up counter B. In addition to the increase, a predetermined control potential is sent to the potential control amplifier 4 so that the potential control amplifier 4 amplifies and outputs the signal volume of the incoming signal by a predetermined level.

다음에는 본 발명의 동작을 설명한다.Next, the operation of the present invention will be described.

먼저 송화자가 수화자에게 전화를 걸게 되면 제 1도에 도시된 착신신호 발생부(1)에서는 소정의 주기로 일정한 착신신호를 발생시킨다. 그 다음에, 상기 착신신호는 착신신호출력부(2)를 거쳐 전위제어증폭부(4)로 입력되는데, 이때 착신신호제어부(3)가 상기 착신신호가 출력되는 횟수(A)를 검출하게 된다.First, when a caller makes a call to the called party, the incoming signal generator 1 shown in FIG. 1 generates a constant incoming signal at a predetermined cycle. Then, the incoming signal is input to the potential control amplifier 4 via the incoming signal output unit 2, where the incoming signal control unit 3 detects the number of times the incoming signal is output. .

여기서, 초기모드시 상기 착신신호제어부(3)의 착신음횟수카운터(A)와 착신음레벨업카운터(B) 및 착신음레벨유지플래그(C)가 제로(0)로 세트되어 있는데, 상기 착신음횟수카운터(A)는 상기 착신신호출력부(2)로부터 하나의 착신신호가 출력될 경우 하나씩 증가해서 5까지 증가하게 되면 상기 착신음레벨업카운터(B)가 하나증가한 후 리세트되게 되어 있고, 상기 착신음레벨업카운터(B)는 상기 착신음횟수카운터(A)가 5로 세트될 동안 수화자가 전화를 받지 않으면 하나씩 증가되게 되며, 상기 착신음레벨유지플래그(C)는 상기 착신음레벨업카운터(B)가 3으로 세트된 후에도 수화자가 전화를 받지 않으면 1로 세트되어 착신음레벨이 초기레벨로 되게 한다.Here, in the initial mode, the ring tone count counter A, the ring tone level up counter B, and the ring tone level maintenance flag C of the ring signal control unit 3 are set to zero, and the ring tone count counter ( A) when one incoming signal is output from the incoming signal output unit 2, increases one by one and increases to five, and the ring tone level up counter B is reset after one increase, and the ring tone level up. The counter B is incremented by one if the receiver does not answer the phone while the ring tone counter A is set to five, and the ring tone level maintenance flag C is set by the ring tone level up counter B to three. If the called party still does not answer the phone after the call is set, it is set to 1 so that the ring tone level becomes the initial level.

이때, 상기 착신신호제어부(3)는 착신신호에 대한 검출을 계속하여 착신음횟수카운터(A)를 계속 증가시켜 가면서 카운트하다가 상기 착신음횟수카운터(A)가 5로 세트되어도 수신자가 전화를 받지 않으면 착신음레벨업카운터(B)를 하나증가시킴과 더불어 상기 착신음횟수카운터(A)를 초기화 시킨다.At this time, the incoming signal control unit 3 continues to detect the incoming signal and continues to increase the number of ringing tone counters A while counting the ringing tone counter A even if the ringing tone counter A is set to 5. The level up counter (B) is increased by one, and the ring tone counter (A) is initialized.

이어서, 상기 전위제어증폭부(4)에는 상기 착신음레벨업카운터(B)의 증가치에 대응하는 제어전위가 인가되게 되어 상기 착신신호출력부(2)로부터 출력되는 착신신호음량에 대한 레벨이 소정치이상 증폭되어 출력되게 된다.Subsequently, a control potential corresponding to the increase value of the ring tone level up counter B is applied to the potential control amplifier 4 so that the level of the incoming signal volume output from the incoming signal output unit 2 is a predetermined value. This is amplified and output.

그리고 나서, 상기 착신신호제어부(3)는 재차 상기 착신신호출력부(1)에서 출력되는 착신신호를 계속 검출하여 초기화되었던 착신신호음횟수카운터(A)를 계속 증가시키고, 이때 상기 착신신호음횟수카운터(A)가 재차 5로 세트되어 수신자가 전화를 받지 않을 경우에는 1로 세트되었던 상기 착신음레벨업카운터(B)가 하나증가되어 2로 세트되면서 이에 대응하는 제어 전위가 상기 전위제어증폭부(4)에 인가됨으로써 착신신호음량에 대한 레벨이 재차 소정치이상 증폭되어 출력되게 된다.Then, the incoming signal control unit 3 again detects the incoming signal output from the incoming signal output unit 1 to continuously increase the incoming signal number counter A which has been initialized, and at this time, the incoming signal number counter ( When A) is set to 5 again and the receiver does not answer the call, the ring tone level up counter B, which has been set to 1, is increased by one and set to 2, so that the control potential corresponding thereto is set to the potential control amplifier 4; When applied to, the level of the incoming signal volume is amplified again by a predetermined value or more and output.

그 다음에, 상기의 과정이 반복되어 착신음레벨업카운터(B)가가 3으로 세트되어도 사용자가 전화를 받지 않을 경우에는 착신음레벨유지플래그(C)가 1로 세트되어 상기 증폭되었던 착신신호음량레벨이 초기화되면서 최초의 착신신호음량레벨상태로 리턴되어 상기와 과정을 반복하게 된다.Then, even if the ring tone level up counter (B) is set to 3 and the user does not answer the call, the ring tone level maintenance flag (C) is set to 1 so that the amplified ring tone level is increased. Initialization is returned to the state of the first incoming signal volume level, and the above steps are repeated.

따라서 상기와 같이 동작하는 본 발명에 의하면, 전화기의 통화대기상태에서 착신신호음이 소정의 횟수 울리더라도 수신자가 전화를 받지 않으면 착신신호음량레벨을 소정레벨 이상으로 증가시켜 출력하고, 이후 증가된 착신신호음량레벨에 대한 착신신호음을 카운트하여 소정의 횟수 울리더라도 수신자가 또 전화를 받지 않으면 재차 착신신호음량레벨을 증가시키는 과정을 반복하고 그래도 수신자가 전화를 받지 않으면 최초의 음량레벨상태로 복귀시킴으로써 수신자가 전화기로부터 멀리 떨어져 있어도 착신신호음을 들을 수 있어서 사용자에게 편의를 제공할 수 있게 된다.Therefore, according to the present invention operating as described above, even if the incoming call tone sounds a predetermined number of times in the call waiting state of the phone, if the receiver does not answer the call, the incoming call volume level is increased to a predetermined level or more, and then the increased incoming call signal Repeat the process of increasing the incoming call volume level again if the receiver does not answer the call even if the receiver receives a call a predetermined number of times, and the receiver returns to the original volume level if the receiver does not answer the call. Incoming ring tone can be heard even if the user is far from the phone to provide convenience to the user.
