Audio reproducing apparatus corresponding to picture

DETAILED DESCRIPTION In view of such aspects, an object of the present invention is to provide an audio reproducing apparatus corresponding to a picture which localizes a position of a reproduced sound image obtained from an audio signal such that the sound image corresponds to a picture.
According to the present invention, an apparatus for reproducing an audio signal corresponding to a video signal includes audio reproducing means and an apparatus body unit for subjecting an audio signal corresponding to a video signal and supplied from an external sound source to a predetermined signal processing.
The audio reproducing means includes an attachment body attached to a listener's head and angle detecting means for detecting a movement of the listener's head with respect to a reference position and direction at every predetermined angle.
The apparatus body unit includes first storage means, second storage means, angle detecting means, A/D converting means, correcting means, D/A converting means, and amplifying means.
The first storage means stores a measured result of an impulse response from a virtual sound source position with respect to the reference position and direction of the head of the listener to both ears of the listener that are fixed.
The second storage means stores a control signal in response to measured results of an arrival time and a sound pressure level of a reproduced and output audio signal from a virtual sound source position with respect to the reference position and direction of the listener's head to both ears of the listener that are fixed and correspond to a movement of the listener's head.
The angle detecting means detects the movement of the listener's head with respect to the reference position and direction and outputting a signal.
The A/D converting means converts the audio signals in respective channels supplied from the signal source.
The correcting means corrects the digital signals from the A/D converting means based on the impulse response stored in the first storage means based on an output signal from the angle detecting means and for correcting the same based on a control signal stored in the second storage means
