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.
