Title: Innovations by Chao Wang in Sound-Absorbing Materials
Introduction
Chao Wang is an accomplished inventor based in Changzhou, China. He has made significant contributions to the field of sound-absorbing materials, holding a total of 4 patents. His innovative approaches have the potential to enhance sound absorption technology, making it more efficient and effective.
Latest Patents
Chao Wang's latest patents include a sound-absorbing material, a method for preparing the same, and a speaker utilizing this sound-absorbing material. The disclosed sound-absorbing material involves a unique process where a sound-absorbing slurry is frozen using a freezing conveyor belt. This method allows for the slurry to be molded or coated onto a film. The pre-cooling of the slurry in the first freezing zone reduces the temperatures of both the mold and the carrier film, followed by rapid freezing in a second zone. This technique ensures uniform freezing of the slurry, enhancing the material's performance. Additionally, the preparation efficiency of the sound-absorbing material is increased, facilitating scalable mass production.
Another notable patent is for a sound absorption material block that features a gradient pore diameter from inside to outside. This block consists of an outer portion with a first pore diameter ranging from 20-200 μm and an inner portion with a second pore diameter ranging from 1-20 μm. The sound absorption material block is designed to have lower damping properties and higher intensity, with a thickness between 0.5-5 mm.
