Humans have an amazing ability of spatializing and locating the sound. Having such an ability, it is a clear evolutionary advantage. The auditory system uses various different cues for location of sound source, such as time and level differences between both ears and spectral information. The vision of paper is to describe the process of reproducing a more natural stereophonic sound giving a realistic sensation in spite of the influence of differences in the shapes of ears or an irregularity of the recording system or the reproducing system, through a combination of an air conduction sound produced through bone conduction by an acoustic output device. Provided is an acoustic output device having an air conduction sound providing unit configured to provide an air conduction sound and a bone conduction sound providing unit configured to provide a bone conduction sound. The bone conduction sound providing unit is positioned near an ear of a user.
