Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of soundproof cabin, concretely is soundproof shield cabin based on sound absorption material. BACKGROUND

[0002] The soundproof shield cabin is a closed structure that isolates external noise from the internal environment through sound insulation, sound absorption, and sealing technology. It is commonly used to provide a quiet space, preventing external noise interference or blocking internal sound from spreading outside. The soundproof shield cabin is widely used in recording studios, medical equipment operating rooms, conference rooms, industrial noise control, electronic equipment test rooms, acoustic laboratories, and other places that require high quietness or noise isolation. Its main functions include isolating external noise, sound absorption, sealing, and noise reduction to ensure the quietness and sound quality of the internal environment.

[0003] The patent with publication number CN214884841U discloses a wallboard assembly unit and a soundproof cabin. The wallboard unit has a cavity in the length direction, and the upper and lower fixed structures at both ends in the height direction. The upper and lower fixed structures can form a detachable fixed connection material in the height direction of the wallboard unit. At least one polymer framework is filled in the cavity to support the wallboard unit. The utility model provides a wallboard assembly unit and a soundproof cabin. The cavity structure of the wallboard unit is increased with a polymer framework, which improves the mechanical properties of the wallboard assembly unit in terms of compression resistance and shear resistance. The cost of the polymer framework is lower than that of the metal profile, ensuring the overall strength of the wallboard assembly unit meets the standard, and reducing the overall cost. The upper and lower fixed structures can realize the assembly and splicing of multiple wallboard assembly units.

[0004] The above-mentioned wallboard unit of the prior art adopts a hollow structure to achieve sound insulation. However, in practice, the sound insulation effect of multiple wallboard units after assembly is still limited. In particular, during the assembly process, the connection between the adjacent wallboard units of the soundproof cabin requires the use of supports, which usually do not have effective sound insulation performance, weakening the overall sound insulation effect of the soundproof cabin. In addition, the material selection and structural design of the supports as the key connection and support parts do not fully consider the sound insulation performance, making it difficult to achieve the expected sound insulation effect and acoustic performance in actual application. Therefore, we propose a soundproof shield cabin based on sound absorption material. UTILITY MODEL CONTENTS
