かる音像定位制御回路であつて、 前記遅延時間Δｔ１を Δｔ１≒ｒ（θ＋ｓｉｎθ）／Ｃ 但し、ｒ；聴取者の頭を球と見做し、その両耳 間距離の１２ θ；聴取者の正面軸から左右スピーカを 見た角度 Ｃ；音速 としたことを特徴とする音像定位制御回路。[Claims for Utility Model Registration] Difference signal generation means for generating a difference signal (L-R) from acoustic signals of left and right L and R channels, and a difference signal (L-R) obtained from this difference signal generation means
a delay time addition means for adding a delay time Δt1 corresponding to the listening distance between the left and right speakers and the listener; and a delay time addition signal obtained from the left L channel acoustic signal and the delay time addition means. and a subtraction means for subtracting the sound signal of the right R channel from the supplied delay time addition signal, and supplying both signals obtained from the addition means and the subtraction means to left and right speakers, respectively. This is a sound image localization control circuit that expands the sound field of acoustic signals of left and right L and R2 channels by The sound image localization control circuit is characterized in that the head is regarded as a sphere, and the distance between the ears is 12 θ; the angle when the left and right speakers are viewed from the front axis of the listener is C; the speed of sound.
