Abstract

본 발명은 2화면 티브이의 무선헤드폰 제어장치에 관한 것으로, 종래의 부화면은 그저 영상만 보는 정도로 되어 있어서 부화면의 음성을 듣고자 할 경우엔 부화면을 주화면으로 바꾸어야 하므로 불편하고, 부화면의 음성을 별도로의 이어폰 단자를 이용하여 들어야 하므로 구조적으로 설계가 복잡해지는 등의 문제점이 있었다.The present invention relates to a wireless headset control device of a two-screen TV, the conventional sub-screen is just enough to see the image, so if you want to hear the voice of the sub-screen to change the sub-screen to the main screen, uncomfortable, sub-screen Because of the need to listen to the earphone using a separate earphone jack, there was a problem such as structurally complicated design.

따라서 종래의 문제점을 해결하기 위하여 본 발명은 부화면 영상이 있으면 무선헤드폰으로 음성을 들을 수 있도록 하고 주화면 음성을 티브이 본체 스피커를 통해 흘러 나오도록 하여 두명이상이 동시에 시청가능하도톡 하고 설계도 용이하도록 한 효과가 있다.Therefore, in order to solve the conventional problems, the present invention allows a user to listen to the audio through a wireless headphone if there is a sub-screen image, and to flow the main screen voice through the TV main body speaker so that two or more people can watch simultaneously and easily design. There is one effect.
