Title: Hongshu Feng: Innovator in Acoustic Technologies
Introduction
Hongshu Feng is a prominent inventor based in Shenzhen, China. He has made significant contributions to the field of acoustic technologies, holding a total of 7 patents. His innovative work focuses on sound-absorbing materials and speaker designs that enhance acoustic performance.
Latest Patents
One of his latest patents is for a sound-absorbing material and speaker box. This invention includes a microporous material and an adsorbate gas that is adsorbed in the microporous material. The microporous material consists of a zeolite molecular sieve, which has a framework and extra-framework cations. The adsorption capacity of the zeolite molecular sieve for the adsorbate gas is greater than its capacity for air. This sound-absorbing material demonstrates excellent application effects, and the speaker box utilizing it offers improved low-frequency acoustic performance.
Another notable patent is for an acoustic absorption material and speaker. This invention features a composite zeolite molecular sieve, which includes two types of zeolite molecular sieves with different micropore diameters. The first zeolite molecular sieve serves as an adsorbent, while the second enhances low-frequency performance. By incorporating a zeolite molecular sieve with a larger diameter, the invention effectively absorbs various volatile organic compounds (VOCs), preventing performance degradation of the low-frequency enhancement material.
