[0002] The soundproof capsule door serves as the entrance and exit for the soundproof capsule. It is made of high-quality soundproofing materials and its design emphasizes sealing performance. In open office environments, the soundproof capsule provides employees with a quiet and independent space for important conference calls, focused work, or private conversations. It effectively blocks external noise interference, improving work efficiency. Whether in the office or other public areas, the soundproof capsule door, when closed, provides users with a relatively private space for private calls, work, or study.

[0003] A search revealed Chinese patent publication number CN217421008U, which relates to the field of noise reduction equipment technology. Specifically, it discloses a novel noise-reducing door, comprising a door frame and a cabin frame. The door frame includes a front and a back side. This novel noise-reducing door features a front mounting groove and a back mounting groove on the front and back sides of the door frame, respectively. Front and back soundproof glass are fixedly mounted and positioned within these grooves, creating a hollow cavity between the front and back soundproof glass and the door frame. This effectively blocks external noise, achieving noise reduction and noise reduction. Furthermore, the surfaces of the soundproof glass are on the same plane as the surfaces of the front and back frames, significantly improving the overall aesthetics of the door frame. A sealing part on the front frame, which engages with the cabin frame, further prevents noise from entering through the door gaps, thus achieving sound insulation. However, when the cabin frame closes, it will collide with the door frame. Due to the lack of effective cushioning measures, the huge shaking will cause a great impact on the door frame, especially the hollow cavity formed between the front and rear soundproof glass and the door frame. Under such strong impact for a long time, cracks will appear at the connection, the sealing performance will be greatly reduced, and the blocking performance against external noise will be worse.
