The present invention is applicable to the field of audio collection and provides a fixed apparatus and an audio collection device. Multiple groups of simulated ear structures are disposed on the fixed apparatus, and the simulated ear structures have simulated ear canal openings used for placing audio collectors. The audio collectors may placed in simulated ear canal openings of the simulated ear structures of the fixed apparatus, so that collected audio signals have richer sources, higher quality, and higher stereoscopic sensation. The fixed apparatus may be used for audio recording in multiple orientations, so that smoothness, clearness, and comfort during sound field fusion and switching are ensured, more complete and richer sound field information is collected, the best sound field naturalness can be obtained, and a requirement for synchronization between a sound and an image in a VR panoramic video technology is met. In addition, a volume of the fixed apparatus is relatively small, and audio sound field restoration accuracy is further improved.

Fixed apparatus and audio collection apparatus

The present invention is applicable to the field of audio recording and provides an audio collection apparatus. Multiple fixed apparatuses are stacked and have ear structures and face contours, and audio collectors are disposed at ear canal openings of the ear structures to collect audio information. During audio collection, faces of the fixed apparatuses have different horizontal orientations, so that the audio collectors obtain the audio information at the ear canal openings of the ear structures towards horizontal directions. Therefore, rich sound sources and sound authenticity are ensured, sounds are rich in quality, a stereo field perception effect is achieved, a real sound field relationship can be restored, an in-head effect is avoided, and a requirement for real synchronization between a sound and an image in a virtual reality (VR) panoramic video technology is met.

Audio collection apparatus

The present invention is applicable to the field of audio recording and provides a recording device and a fixed apparatus. The recording device includes several fixed apparatuses that are stacked, and the fixed apparatus has a first fixed structure and a second fixed structure; the first fixed structure includes a first simulated face structure and first simulated ear structures, and the first simulated ear structures simulate a mutual position relationship between human ears and a human face and are disposed on two sides of the first simulated face structure; the second fixed structure includes a second simulated face structure and second simulated ear structures; the second simulated face structure and the first simulated face structure are inverted to each other, and the second simulated ear structures and the second simulated face structure are inverted to each other; and audio collectors are disposed at simulated ear canal openings of the first simulated ear structures and the second simulated ear structures.
