Abstract

【課題】　サラウンドチャンネルの再生音がフロントチャンネル用スピーカードライバーからの再生音と干渉すると、壁などの反射と同様、明確な定位感を得ることが出来ない。 【解決手段】　フロントＬチャンネル、フロントセンターチャンネル、フロントＲチャンネルを再生するためのスピーカードライバーが取り付けられ、テレビ画面下側に設置される第1のスピーカーボックスと、サラウンドＬチャンネル及びサラウンドＲチャンネル用スピーカードライバーが取り付けられ、テレビ画面の上部に設置される第２のスピーカーボックスと、ラウンドＬチャンネル及びサラウンドＲチャンネル用スピーカードライバーに入力される再生信号を信号処理し、ラウンドＬチャンネル及びサラウンドＲチャンネル用スピーカードライバーが設置されている場所とは異なる場所に音源を定位させるバーチャライザーとを備える。
