Abstract
To provide a sound image adjustment method and a volume adjustment method for correcting the offset of a sound image sensed by a user, and an audio output device and a volume adjustment method for correcting the volume difference between left and right speakers caused by the mass difference of the mechanical structures of the speakers placed against the left and right ears.SOLUTION: A sound image adjustment method obtains a volume difference between a first sound wave and a second sound wave, and adjusts a time difference between the first sound wave and the second sound wave. The volume adjustment method obtains a volume difference between the first sound wave and the second sound wave, and adjusts an amplitude difference between the first excitation and the second excitation. An audio output device corrects an offset of the sound image perceived by a user due to a mass difference between the first mechanical structure and the second mechanical structure. The audio output device also corrects a volume difference between the first speaker and the second speaker due to a mass difference between the first mechanical structure and the second mechanical structure.SELECTED DRAWING: Figure 9
