PURPOSE: To insure sound from a central speaker against being interrupted by a screen, to accomplish large speakers even if the screen is made larger and to increase power and presence by placing three-channel tweeters and three-channel woofers on a screen frame and installing said frame.
CONSTITUTION: The central-channel tweeter 2, the central-channel woofer 3, the left-channel tweeter 4, the left-channel woofer 5, the right-channel tweeter 6 and the right-channel woofer 7 are fitted to the screen frame 8. In this constitution, sound from the three channels (right, center and left) is divided into a high-pitched sound and a low-pitched sound, which are outputted. Thus, central sound is not interrupted by the screen 1, and an installation space is reduced. In addition, the speakers are made larger in size as well as the screen, and power and presence, thereby, are imparted.
