Title: Audio reproducing device
Inventor: TATSUTA KAZUHITO
IPC: H04S1/00
Filed: 2001-08-10
Abstract: PROBLEM TO BE SOLVED: To realize a sound field full of presence. SOLUTION: A center channel audio signal Cn passes through a high pass filter HPF and a low pass filter LPF, from which high and low frequency components Cn1, Cn2 are produced and the high frequency component Cn is fed to a center channel loudspeaker SPC. Further, the low frequency component Cn2 passes through phase shifters 2, 3 from which two low frequency components Cn2L, C2n2R with different phases are produced. Adding the low frequency component Cn2L to a left front channel audio signal FL produces a summed audio signal SL, which is fed to a loudspeaker SPL of a left front channel. Adding the low frequency component Cn2R to a right front channel audio signal FR produces a summed audio signal SR, which is fed to a loudspeaker SPR of a right front channel.  Thus, both ear correlation coefficients of sounds outputted from the left right front channel loudspeakers SPL, SPR are corrected and a sound image of a vocal sound outputted from a center channel loudspeaker SPC is localized at a natural position to provide a sound field full of presence.
