Abstract

The present invention provides a loudspeaker module, which includes a housing and a loudspeaker unit housed in the housing. The loudspeaker unit separates the cavity formed by the housing into a front acoustic cavity and a rear acoustic cavity; wherein, the rear acoustic cavity is filled with sound-absorbing materials ; The crystal structure of the sound-absorbing material is doped with heteroatoms. The above invention can reduce the absorption of heterogeneous molecules by the sound-absorbing material inside the speaker module, and even repel the heterogeneous molecules, thereby ensuring the long-term effectiveness of the sound-absorbing material and improving the stability of the acoustic performance of the speaker 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...
