Abstract

본 발명은 텔레비젼의 볼륨 자동조절 장치에 관한 것으로, 특히 리모콘으로부터 송신되어진 적외선 및 초음파의 도달시간차를 계산하여 그에 따라 볼륨의 레벨을 자동으로 조정할 수 있는 텔레비젼의 볼륨 자동조절 장치에 관한 것으로, 일반적인 텔레비젼의 볼륨 자동 조정장치의 경우에 반사파를 이용함으로써, 시청자외에 다른 물체에 반사되어온 신호의 방해에 의해 볼륨조정의 정확도가 떨어지는 문제점이 있으며, 다수의 사람이 시청하고 있을 때에 거리차를 구할 경우 특정 시청자까지의 거리가 아닌 텔레비젼으로부터 가장 가까운 곳에 위치한 시청자까지만의 거리를 구하여 볼륨을 조정함으로써 텔레비젼으로부터 멀리 떨어져 있는 시청자는 만족할 만한 음의 크기를 느끼지 못하는 문제점이 있었으나, 본 발명에서는 리모콘으로부터 송신되어진 적외선 및 초음파의 도달시간차를 계산하여 그에따라 볼륨의 레벨을 자동으로 조정함으로써, 거리감지기능이 작동된 후 시청자가 텔레비젼 앞에서 이동하게 되더라도 또다시 볼륨을 조정할 필요가 없는 한편 여러 사람이 텔레비젼을 시청하고 있는 경우에도 리모콘을 가지고 있는 특정시청자를 기준으로 거리가 측정되어 거리정도를 자유로이 할 수 있으며, 이로인해 시청자외에 다른 물체에 반사되어온 신호의 방해에 의한 볼륨조정의 정확도가 떨어지는 문제점을 해결하는 효과가 있게 된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically adjusting the volume of a television, and more particularly, to a device for automatically adjusting a volume of a television that can calculate a difference in arrival time of infrared rays and ultrasonic waves transmitted from a remote controller and automatically adjust the level of the volume accordingly. In the case of the automatic volume control device, the accuracy of the volume adjustment is lowered due to the interference of the signal reflected to other objects besides the viewers. The viewer far away from the television did not feel satisfactory sound volume by adjusting the volume by obtaining the distance only to the viewer located closest to the television, not the distance to the TV. By calculating the time difference between the far infrared and the ultrasonic waves and automatically adjusting the volume level accordingly, even if the viewer moves in front of the television after the distance sensing function is activated, the volume is not needed to be adjusted again. Even if it is, the distance is measured based on the specific viewer who has the remote control, and the distance can be freely set. This reduces the accuracy of volume adjustment caused by the interference of signals reflected from other objects other than the viewer. Will be.

사용자로부터 특정키를 통해 거리감지명령이 거리감지명령이 입력되면 이를 디코딩하여 그에 해당하는 적외선신호 및 초음파신호를 동시에 발생하여 송신하는 리모콘과, 상기 리모콘에 의해 송신된 적외선신호를 수신하는 적외선 수신부와, 상기리모콘에 의해 송신된 초음파신호를 수신하는 초음파 수신부와, 상기 적외선 수신부에 적외선신호가 수신되면 거리감지명령에 대한 신호인가를 판별하여 거리감지명령이면 시간을 계수하기 시작하며 상기 초음파 수신부에 초음파신호가 수신되면 시간 계수를 종결하여 그 두 신호사이의 도달시간차를 계산함으로써 거리데이타로 환산하고 그 거리데이타에 대한 볼륨조정데이타를 메모리에서 읽어와서 출력하는 마이크로컴퓨터와, 상기 마이크로컴퓨터에서 계산된 두 신호사이의 도달시간차에 따른 볼륨조정데이타를 저장하고 있는 메모리와, 입력되는 음성신호를 상기 마이크로컴퓨터로부터 출력되는 볼륨조정데이타에 의해 증폭정도를 제어하여 스피커로 출력하는 증폭부로 구성하여 된 것을 특징으로 하는 텔레비젼의 볼륨 자동조절 장치.When the distance detection command is input to the distance detection command through a specific key from the user, the remote control for decoding and generating the corresponding infrared signal and the ultrasonic signal at the same time, and the infrared receiver for receiving the infrared signal transmitted by the remote control; And an ultrasonic receiver for receiving the ultrasonic signal transmitted by the remote control, and when the infrared signal is received by the infrared receiver, determines whether it is a signal for a distance sensing command and starts counting the time if the distance sensing command is received. When a signal is received, the microcomputer converts the distance data by calculating the time difference between the two signals by terminating the time coefficient, and reads the volume adjustment data for the distance data from the memory and outputs the two data calculated by the microcomputer. Volume according to difference of arrival time between signals And a memory for storing the adjustment data, and an amplifying unit for controlling the amplification degree by the volume adjustment data outputted from the microcomputer and outputting the audio signal to the speaker. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
