Patent ID: 8116458

Claim:
An acoustic image localization apparatus that outputs sound from a plurality of speakers so as to localize an acoustic image at a predetermined position or direction on a space as viewed from a listener, the acoustic image localization apparatus comprising: in a low frequency band, amplitude phase characteristic adjusting means, provided so as to respectively correspond to the plurality of speakers, for adjusting an amplitude phase frequency characteristic such that a first acoustic image is localized at the predetermined position, while performing a crosstalk cancellation process on an inputted acoustic signal; in a high frequency band, amplitude characteristic adjusting means for adjusting an amplitude frequency characteristic of the inputted acoustic single such that a second acoustic image is localized in a direction rotated by a first angle about a position of a listener toward an upper direction from a facing direction of the listener; and level adjusting means, provided so as to respectively correspond to the plurality of speakers, for adjusting a level of the acoustic signal outputted from the amplitude characteristic adjusting means and for outputting, to a corresponding speaker, the acoustic signal whose level has been adjusted, such that a third acoustic image is localized in a direction rotated by the second angle toward the predetermined direction from the direction rotated by the first angle, wherein the low frequency band at least includes a frequency lower than or equal to approximately 1 kHz, and the high frequency band at least includes a frequency higher than or equal to approximately 4 kHz.
