Abstract

The invention discloses a gas absorbing material block, which comprises a main body structure formed by a zeolitic material bonded by a binder, and a plurality of cavitation bubbles randomly distributed in the main body structure, wherein the cavitation bubbles are obtained by decomposing a foaming agent or a pore-forming agent.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a gas-absorbing material block and a manufacturing method thereof. Background technique [0002] Loudspeaker is an important component in electroacoustic products, which is used to convert electrical signals into sound signals. The inner cavity of the loudspeaker is divided into two cavities, the front cavity and the rear cavity, and the rear cavity is also called a resonant cavity. In order to improve the acoustic performance, sound-absorbing parts are usually added in the rear acoustic cavity to absorb part of the sound energy, which is equivalent to expanding the volume of the resonant cavity, thereby reducing the resonant frequency of the speaker module. The sound-absorbing parts can also be called gas absorption. pieces. [0003] With the increasingly thinner and lighter electronic products, the speaker is also continuously developing towards flatness, which makes the...
