The invention discloses sound absorption foam with a good sound insulation effect, relates to the technical field of sound absorption devices, and solves the problems that a sound absorption device ispoor in sound insulation effect and inconvenient to assemble, connect and use, so the sound absorption foam thereof is inconvenient to install or replace. The invention discloses the sound absorptionfoam with a good sound insulation effect; a buffer shell is included, and a sealing plate is mounted at one end of the buffer shell; a limiting circular groove is formed in one end of the sealing plate; a second spring is mounted on the inner side of the buffer shell; a supporting shell is mounted on one side of the second spring; the sound absorption device is installed on the inner side of thesupporting shell, a limiting groove is formed in one side of the buffer shell, clamping columns are installed at the two ends of the limiting groove, a limiting disc is installed at one end of each clamping column, a pull column is installed at one end of each limiting disc, a first spring is installed on the outer surface of each pull column, and a pulley is installed on the inner side of each limiting disc. The sound-absorbing foam is good in sound-insulating effect, convenient to assemble, connect and use and convenient to install or replace.
Description
technical field [0001] The invention relates to the technical field of sound-absorbing devices, in particular to a sound-absorbing foam with good sound-insulating effect. Background technique [0002] With the rapid development of social economy, the sound-absorbing device is also called sound-absorbing material or sound-absorbing sponge. High-quality auxiliary materials, sound-absorbing device materials made by high-temperature mixing and foaming. The sound-absorbing device is mainly divided into PU sponge, open-cell PE foam, open-cell PDM rubber foam material, open-cell WR rubber-plastic foam material, etc. Unique formula, pure raw materials, fine workmanship, environmental protection and non-toxic, sound-absorbing purpose is to control the appropriate reverberation time, so that the sound is full, mellow and elastic. Therefore, sound-absorbing devices are widely used in many fields such as automobiles, trains, subways, airplanes, ships, air conditioners, chemicals, inst...
