Abstract

본원 발명은 휴대장치와 고정장치의 거리에 따라 가청신호를 발생하여 고정장치의 위치를 알려주는 시각장애자용 무선전화기에 관한 것으로서, 휴대장치 및 고정장치를 포함하여 이루어지는 무선전화기에 있어서; 상기 휴대장치는 입력되는 키(key)를 인식하는 버튼인식부와, 상기 버튼인식부의 출력에 따라 휴대장치를 제어하는 제1제어부와, 상기 제1제어부의 제어신호에 따라 고주파신호를 발생하는 전파발생부로 구성되고; 상기 고정장치는 상기 휴대장치의 전파발생부에서 출력되는 전파의 세기를 감지하는 전파감지부와, 상기 전파감지부의 출력에 따라 고정장치를 제어하는 제2제어부와, 상기 제2제어부의 제어신호에 따라 가청신호를 발생시키는 가청신호 발생부와, 상기 가청신호 발생부의 출력에 따라 경고음을 출력하는 스피커구동부 및 스피커로 구성되어; 상기 고정장치에서 상기 휴대장치와의 거리에 따라 음량 및 주파수가 다른 경고음을 발생함으로써 고정장치의 위치파악이 용이하게 되는 것을 특징으로 한다.The present invention relates to a wireless telephone for the visually impaired by generating an audible signal according to the distance between the portable device and the fixed device to indicate the location of the fixed device, the wireless phone comprising a portable device and a fixed device; The portable device includes a button recognition unit for recognizing a key to be input, a first control unit for controlling the portable device according to an output of the button recognition unit, and a radio wave for generating a high frequency signal according to a control signal of the first control unit. A generator; The fixing device includes a wave detection unit for detecting the intensity of the radio wave output from the radio wave generation unit of the portable device, a second control unit for controlling the fixing unit according to the output of the wave detection unit, and a control signal of the second control unit. And an audible signal generator for generating an audible signal, a speaker driver for outputting a warning sound according to the output of the audible signal generator, and a speaker; The fixing device may be configured to easily detect the position of the fixing device by generating a warning sound having a different volume and frequency depending on the distance from the portable device.
