안테나에 수신된 수신 신호의 전계강도가 약하게되면 스피커로는 수신신호와함께 지직 거리는 잡음이 크게 출력된다.When the electric field strength of the received signal received by the antenna is weak, loud noise is outputted to the speaker along with the received signal.

종래에는 본 발명과 같은 스피커 출력 자동 절환장치가 제공되지 않았기 때문에 터널등의 난청지역을 통과할때에는 카 오디오의 스피커를 통해 지직하는 잡음이 그대로 운전자에게 제공되어 운전자가 불쾌감을 느끼는 문제점이 있었다.Conventionally, since the speaker output automatic switching device is not provided as in the present invention, when passing through a hearing loss area such as a tunnel, the noise that is delayed through the speaker of the car audio is provided to the driver as it is, so that the driver feels uncomfortable.

따라서, 상기 문제점을 해결하기 위한 본 발명은 안테나에 수신된 수신 신호의 전계강도를 감지하고, 감지결과 전계강도가 낮다고 판단되면 미리 저장해 두었던 안내음성 또는 음악등을 스피커를 통해 출력하므로서, 터널등의 난청지역을 통과할 때 스피커를 통해 잡음이 출력되지않아 사용자가 불쾌감을 느끼지 않도록 하는 난청 지역 통과시 스피커 출력 자동 절환장치를 제공함을 목적으로 한다.Accordingly, the present invention for solving the above problems is to detect the electric field strength of the received signal received by the antenna, and if it is determined that the electric field strength is low, and outputs the pre-stored voice or music through the speaker, such as tunnel, It is an object of the present invention to provide a speaker output automatic switching device when passing through a hearing loss zone so that the user does not feel uncomfortable because noise is not output through the speaker.

도면 제1도는 상기 목적달성을 위한 본 발명의 난청 지역 토오가시 스피커 출력 자동 절환장치를 도시한 것으로서, 안테나(ANT)에 수신된 음성신호를 스피커(2)를 통해 출력하는 카 오디오(1)와, 안테나(ANT)에 수신된 수신신호의 전계강도를 검출하는 전계강도 검출부(3)와, 상기 전계강도 검출부(3)에서 검출된 전계강도로 현재 채널의 수신상태를 판단하고, 그 판단결과 수신상태가 안좋다고 판단되면 카 오디오(1)의 음성신호 출력을 차단하고 미리 저장해두었던 소정의 음성신호가 출력되도록 제어하는 제어부(4)와, 안내음성이나 경음악과 같은 소정의 음성신호를 저장하며, 상기 제어부(4)의 제어신호에 따라 저장되었던 음성신호를 출력하는 메모리(5)와, 상기 메모리(5)에서 출력되는 디지털 음성신호를 아날로그 신호로 변환시켜 스피커(2)로 출력하는 D/A변환부(6)로 구성된다.FIG. 1 is a diagram illustrating an auto-switching device for hearing loss Togashi speaker output of the present invention for achieving the above object, wherein the car audio 1 outputs a voice signal received through an antenna ANT. And the electric field strength detection unit 3 for detecting electric field strength of the received signal received by the antenna ANT and the electric field strength detected by the electric field strength detection unit 3 to determine the reception state of the current channel. If it is determined that the reception state is not good, the control unit 4 for blocking the output of the audio signal of the car audio (1) and controls to output a predetermined voice signal stored in advance, and stores a predetermined voice signal such as guide voice or instrumental music, Memory 5 for outputting the audio signal stored in accordance with the control signal of the control unit 4 and D for converting the digital audio signal output from the memory 5 to an analog signal and output to the speaker (2) / A conversion section (6).

이와같이 구성된 본 발명은 동작을 설명하면 다음과 같다.The present invention configured as described above will be described below.

운전자가 카 오디오(1)를 이용하여 일정 채널의 라디오 방송을 들으면서 자동차를 운전하다가, 자동차가 터널과 같은 난청지역으로 진입하면, 전계강도 감지부(3)는 안테나(ANT)에 수신된 수신신호의 전계강도를 감지하여 제어부(4)로 출력하고, 상기 제어부(4)는 전계강도 감지부(3)로부터 입력되는 데이터를 이용하여 현재 수신되는 채널의 수신감도를 파악한다.When the driver drives the car while listening to a certain channel radio broadcast using the car audio 1, and the car enters a hearing loss area such as a tunnel, the electric field strength detecting unit 3 receives a received signal received by the antenna ANT. The electric field strength of the electric field is sensed and output to the control unit 4, and the control unit 4 determines the reception sensitivity of the channel currently received using the data input from the electric field strength detecting unit 3.

상기 판단결과 현재 채널의 수신감도가 아주 나쁘다고 판단되면, 제어부(4)는 방송 신호 대신 소정의 안내방송 또는 경음악이 출력되도록 하기위한 제어신호를 출력하고, 메모리(5)는 상기 제어부(4)에서 출력된 제어신호에 따라 동작하여 저장하고 있던 소정의 메시지 또는 경음악과 같은 디지털 음성신호를 출력하고, D/A 변환부(6)는 상기 메모리(5)에서 출력되는 디지털 음성신호를 아날로그 신호로 변환하여 스피커(2)를 통해 출력하므로서, 터널과 같은 난청지역을 통과하는 운전자는 지직 거리는 잡음대신 잔잔한 경음악이나 소정의 메시지를 들을 수 있게되는 것이다.If it is determined that the reception sensitivity of the current channel is very bad, the controller 4 outputs a control signal for outputting a predetermined announcement or light music instead of a broadcast signal, and the memory 5 is controlled by the controller 4. A digital voice signal such as a predetermined message or instrumental music stored by operating according to the output control signal is output, and the D / A converter 6 converts the digital voice signal output from the memory 5 into an analog signal. By outputting through the speaker 2, the driver passing through the deafness area, such as a tunnel, is able to listen to the soft light music or a predetermined message instead of the noise.

이상에서 설명한 바와같이 본 발명은 안테나 수신된 수신신호의 전계강도를 감지하고, 감지결과 전계강도가 낮다고 판단되면 미리 저장해 두었던 안내음성 또는 음악등을 스피커를 통해 출력하므로서, 터널의 난청지역을 통과할때 스피커를 통해 잡음이 출력되지않아 사용자가 불쾌감을 느끼지 않도록 하는 난청 지역 통과시 스피커 출력 자동 절환장치 이다.As described above, the present invention senses the electric field strength of the received signal received from the antenna, and if it is determined that the electric field strength is low, it outputs the pre-stored voice or music through the speaker and passes through the tunnel deafness region. It is a speaker output automatic switching device when passing through the hearing loss area so that the user does not feel uncomfortable because noise is not output through the speaker.
