Claims (1)

핸드폰 통화장치에 있어서, 멜로디장치 (ML)의 출력(OUT)은 트랜지스터(Q1)의 베이스에, 전원(Vcc)은 제너 다이오드(D1)와 송신 스위치(SW0)에 각각 접속되고, 송화용 마이크(MIC)는 콘덴서(C1)를 통해 트랜지스터(Q2)의 베이스에 역결되며, 트랜지스터(Q1,Q2)의 콜렉터는 트랜스(T)1차에, 에미터는 콘덴서(C2)와 수화용 스피커(SP)가 연결된 트랜스(T) 2차에 각각 연결한 것을 핸드폰에 내장하여서된 것을 특징으로 하는 핸드폰 장치.In the cellular phone communication apparatus, the output OUT of the melody device ML is connected to the base of the transistor Q 1 , the power supply V cc is connected to the zener diode D 1 and the transmission switch SW 0 , respectively. The MIC for transmission is reversed to the base of transistor Q 2 through condenser C 1 , the collectors of transistors Q 1 and Q 2 are in the primary of transformer T, and the emitter is condenser C 2 . Mobile phone device, characterized in that the built-in cell phone connected to each of the secondary transformer (T) connected to the sign language speaker (SP). ※ 참고사항 : 최초출원내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
