Abstract

The invention provides a loudspeaker module. The loudspeaker module comprises a shell and a loudspeaker monomer contained in the shell, wherein the loudspeaker monomer divides a cavity formed by the shell into a front vocal cavity and a rear vocal cavity; the rear vocal cavity is filled with acoustic materials; heteroatoms are doped in the crystal structures of the acoustic materials. The loudspeaker module provided by the invention can reduce the adsorption of acoustic materials inside the loudspeaker module to heterogeneous molecules, and even reject the heterogeneous molecules, so as to guarantee that the acoustic materials are long-term effective and improve the stability of the acoustical property of the loudspeaker module.

Description

technical field [0001] The present invention relates to the technical field of acoustics, and more specifically, to a loudspeaker module. Background technique [0002] With the progress of society and the development of technology, wearable electronic products are becoming thinner and thinner. Traditional sound-absorbing materials can no longer meet the needs of the micro-speaker industry for debugging and correcting the acoustic performance of speakers. Therefore, people continue to try or develop new sound-absorbing material. It has been verified that placing a porous sound-absorbing material in the rear acoustic cavity of the speaker device can effectively improve the acoustic performance of the speaker. [0003] At present, the commonly used new sound-absorbing materials with better effects mainly include natural zeolite, activated carbon, white carbon black, sepiolite wool, synthetic zeolite powder with a silicon-aluminum ratio of more than 200, or a mixture of the abo...
