Claims (1)
- 【特許請求の範囲】 1.画像スクリーン、画像を画像スクリーン上に表示させる手段、制御信号に応 答して音波を発生する電気−音響手段、及び制御信号を電気−音響手段に加える 音声信号源を有する音声−映像手段装置において、電気−音響手段は、画像スク リーンの制御に取付けられた複数の電気−音響変換機であり、制御信号を発生す る手段は、相互の信号の強さの比が、画像スクリーンに略々真向かいの聴視領域 内に集中される値を有する制御信号で電気−音響変換機を駆動するように配設さ れたことを特徴とする音声−映像装置。 2.予め決められた使用者定位に対し、画像はスクリーン上に直立位置で表示さ れ、予め決められた使用者定位で、少なくとも複数の変換機が画像スクリーンの 上側および/または下側に沿って均等に間をおいて置かれた請求項1記載の音声 −映像装置。 3.予め決められた使用者定位に対し、少なくとも複数の変換機が画像スクリー ンの左側および/または右側に沿って均等に間をおいて置かれた請求項2記載の 音声−映像装置。 4.画像スクリーンの互いに向き合った2つの側部に沿った変換機の位置は、画 像スクリーンの同じ側部に位置する2つの続いた変換機間の距離の半分に等しい 距離にわたって互いにずらされた請求項2または3記載の音声−映像装置。 5.側部の少なくとも1つに沿って位置する変換機の数は4である請求項1乃至 4のいずれか1項記載の音声−映像装置。 6.外側の2つの変換機に対する制御信号の強さと内側の2つの変換機に対する 信号の強さ間の比は2である請求項4記載の音声−映像装置。 7.請求項1乃至6のいずれか1項記載の音声−映像装置、少なくとも1つの追 加の電気−音響変換機及び前期の音声−映像装置で発声された音に相当する音声 入力信号を受信するために音声−映像装置と結合された信号プロセッサを有し、 この信号プロセッサは、更に、音響−電気変換機で受けた音に相当する測定信号 を受信するために該音響−電気変換機と結合され、前期の追加の電気−音響変換 機に補償信号を供給するために該変換機と結合され、測定信号内の始 めの音声信号の信号成分の存在を減らすように音声信号と測定信号に応答して補 償信号を取出す信号処理手段を有することを特徴とするシステム。 8.信号プロセッサは、音声周波数スペクトルの低周波数範囲内に位置する周波 数を有する信号成分の存在を減少するように配設された請求項7記載のシステム 。 9.システムは、追加の音声信号に相当する音の再生のために、追加の変換機に 追加の制御信号を加える別の音声信号源を有する請求項7または8記載のシステ ム。
