Abstract

본 발명은 스피커 출력 자동 절환장치에 관한 것으로서, 안테나에 수신된 수신신호의 전계강도가 약하게 되면 스피커로는 수신신호와 함께 지직거리는 잡음이 크게 출력된다.The present invention relates to an automatic speaker output switching device, and when the electric field strength of a received signal received by the antenna is weak, a 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 통과할 때에는 카 오디오의 스피커를 통해 지직하는 잡음이 그대로 운전자에게 제공되어 운전자가 불쾌감을 느끼는 문제점이 있었다.In the related art, 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 수신신호의 전계강도를 감지하고, 감지결과 전계강도가 낮다고 판단되면 미리 저장해 두었던 안내음성 또는 음악등을 스피커를 통해 출력하므로서, 터널등의 난청지역을 통과할때 스피커를 통해 잡음이 출력되지 않아 사용자가 불쾌감을 느끼지 않도록 하는 난청 지역 통과시 스피커 출력 자동 절환장치이다Therefore, the present invention for solving the above problems is to sense the electric field strength of the received signal received by the antenna, if the detection result is determined that the electric field strength is low by outputting the pre-stored voice or music through the speaker, such as tunnel It is a speaker output automatic switching device that passes through the hearing loss area so that the user does not feel uncomfortable because noise is not output through the speaker.
