Intellectual Property India Publishes Patent Application for 'Porous Acoustic Volume Increasing Material And Preparation Method Therefor, Loudspeaker, And Electronic Device' Filed by SSI New Material (ZHENJIANG) Co. Ltd.

MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202517062177 A) filed by SSI New Material (ZHENJIANG) Co. Ltd., Jiangsu, China, on June 30, for 'porous acoustic volume increasing material and preparation method therefor, loudspeaker, and electronic device.'

Inventor(s) include Lu, Junran; Zhang, Lei; Guo, Mingbo; and Ma, Yuanhong.

The application for the patent was published on July 25, under issue no. 30/2025.

According to the abstract released by the Intellectual Property India: "The present invention provides a porous acoustic volume increasing material and a preparation method therefor, a loudspeaker, and an electronic device. The porous acoustic volume increasing material comprises covalent organic frameworks (COFs), wherein the COFs have a thermal decomposition temperature Td greater than or equal to 300 C, a density greater than or equal to 0.20 g/cc, and a particle specific surface area greater than or equal to 200 m2/g. Acoustic impedance and frequency response analysis tests prove that the porous acoustic volume increasing material comprising the COFs can show excellent low-frequency improvement performance. In particular, the acoustic performance of the porous acoustic volume increasing material comprising the COFs having the specific Td (i.e., Td=300 C) is more excellent."

The patent application was internationally filed on Nov. 30, 2023, under International application No.PCT/CN2023/135370.
