Kind Code:
A1
Abstract:
Provided is an audio acquisition apparatus; by means of a plurality of fixtures (10) arranged stacked on top of one another and having face contours, an audio acquisition device (20) is disposed at the openings of the ear canal of ear structures (101) so as to acquire audio information; when acquiring audio, the faces of the fixtures (10) face in different directions horizontally, such that the audio acquisition device (20) obtains the audio information of the ear canal openings of the ear structures (101) facing in all horizontal direction; thus the rich sound sources and authenticity of sound are preserved, the texture is rich and there is a 3-D acoustic-field perception effect, and a true acoustic-field relationship is restored; an in-head effect is prevented, satisfying the requirements of VR panoramic-video technology, in which sound and picture are truly synchronized.
