Abstract
본 발명은 셀룰러 폰의 착신신호 감지장치에 관한 것으로, 송/수신 안테나로부터 송신 및 수신된 고주파 신호를 양방향으로 전송하는 듀플렉서 및 상기 듀플렉서를 통하여 수신된 고주파 신호를 검파하여 가청음 신호로 변환하는 수신부 및 음성신호를 고주파 신호로 변조하여 상기 듀플렉서를 경유하여 공중에 전파하는 송신부로 구성된 셀룰러 폰을 포함하여 이루어진 셀룰러 폰의 착신신호 감지장치에 있어서, 상기 셀룰러 폰은, 원거리에 있는 기지국으로부터 출력된 착신신호가 상기 송/수신 안테나에 유기될 경우 상기 듀플렉서를 경유하여 저주파 착신신호를 공중에 전파하는 착신신호 발생부를 구비하고; 상기 듀플렉서 및 송/수신 안테나를 통하여 출력된 상기 착신신호 발생부의 저주파 착신신호를 감지하는 착신신호 감지센서와, 상기 착신신호 감지센서를 통하여 감지된 착신신호를 저전압 증폭시키는 저전압 증폭부와, 일정한 전원전압을 공급하는 전원부와, 상기 전원부의 전원전압에 의하여 구동되어 상기 저전압 증폭부를 통하여 증폭된 착신신호를 제어신호로 변환하는 콘트롤러와, 상기 콘트롤러의 제어신호를 인가받아 부저 구동신호로 변환하는 부저 구동부와, 상기 부저 구동부의 부저 구동신호에 의하여 부저음을 발생하는 부저를 포함하여 이루어진다. 따라서, 셀룰러 폰으로부터 떨어져 있는 가입자에게 직접 전화가 왔음을 인지시켜 줄 수 있는 탁월한 효과가 있다.The present invention relates to an apparatus for detecting an incoming signal of a cellular phone, comprising: a duplexer for transmitting a high frequency signal transmitted and received from a transmitting / receiving antenna in both directions, and a receiving unit for detecting a high frequency signal received through the duplexer and converting it into an audible signal; An apparatus for detecting an incoming signal of a cellular phone, comprising a cellular phone comprising a transmitter configured to modulate an audio signal into a high frequency signal and propagate the air via the duplexer, wherein the cellular phone is an incoming signal output from a base station located at a remote location. An incoming signal generator for propagating a low frequency incoming signal to the air via the duplexer when is induced by the transmit / receive antenna; An incoming signal detection sensor for detecting a low frequency incoming signal of the incoming signal generation unit output through the duplexer and a transmission / reception antenna; a low voltage amplifier for low voltage amplification of the incoming signal detected through the incoming signal detection sensor; A power supply unit for supplying a voltage, a controller driven by the power supply voltage of the power supply unit, and converting an incoming signal amplified by the low voltage amplifier into a control signal, and a buzzer driving unit receiving the control signal of the controller and converting it into a buzzer driving signal. And a buzzer for generating a buzzer sound by the buzzer driving signal of the buzzer driver. Therefore, there is an excellent effect of notifying that the call comes directly to the subscriber away from the cellular phone.
