Abstract

1. 청구범위에 기재된 기술분야1. Technical field described in the claims

전화기에 있어서 스피커폰 구현빙법에 관한 것으로, 특히 후크스위치를 이용하여 수화기를 놓았을때 스피커폰 기능을 실현토록 루프가 형성되고 수화기를 들었을때 일반통화가 수행토록 겸용할 수 있는 방법 및 장치에 관한 것이다.The present invention relates to a method for implementing a speakerphone in a telephone, and more particularly, to a method and an apparatus in which a loop is formed to realize a speakerphone function when a receiver is placed using a hook switch, and a general call can be performed when the receiver is picked up.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

단일 스피커와 마이크를 이용하여 후크스위치에 의해 루프를 전환함으로써 스피커폰 통화와 핸드세트 통화기능을 겸용할 수 있어 원자 절감을 할 수 있는 방법을 제공함.By using a single speaker and a microphone to switch the loop by hookswitch, speakerphone call and handset call function can be used together, thus providing a method of saving atomicity.

3. 발명의 해결 방법의 요지3. Summary of the Solution of the Invention

후크스위치를 이용하여 수화기를 놓았을때에는 수화기의 스피커와 마이크가 스피커폰 기능을 구현하기 위한 루프로 연결되고, 수화기를 들었을때는 마이크와 스피커가 핸드세트로 통화를 할 수 있도록 루프를 전환시켜 줌으로써 단일 스피커와 단일 마이크를 사용함으로써 핸드세트 통화와 스피커폰 통화가 가능토록 함.When the handset is placed using the hook switch, the speaker and microphone of the handset are connected in a loop to implement the speakerphone function, and when the handset is picked up, the speaker is switched by switching the loop so that the microphone and speaker can talk to the handset Using a single microphone with handset calls allows speakerphone calls.
