Abstract

A loudspeaker module which comprises a housing having an accommodation space and a loudspeaker unit accommodated in the housing, the loudspeaker monomer divides the accommodation space into a front chamber and a rear chamber, The housing is provided with a sound outlet communicating with the front cavity, and the loudspeaker module further comprises a sealing assembly covering the sound outlet, the sealing assembly comprising a hard glue injection layer surrounding the sound outlet and a micro-foamed injection layer attached to the hard glue injection layer. The invention improves the bondingforce between the sealing assembly and the housing and the bonding force inside the sealing assembly, thereby improving the reliability of the product, reducing the cost and facilitating the mechanized production.

Description

technical field [0001] The invention relates to the field of electroacoustic conversion, in particular to a loudspeaker module and a preparation method of the loudspeaker module. Background technique [0002] With the advent of the mobile Internet era, electronic products are being updated faster and faster, and people have higher and higher requirements for the performance of electronic products. One of them is the high-quality music function. Therefore, the electroacoustic system It is necessary to continuously improve performance, and a high-quality speaker module is one of the prerequisites for realizing this high-quality music function. [0003] The speaker module usually includes a casing and a speaker unit accommodated in the casing, and the sound emission of the speaker module is realized by providing a sound outlet on the casing. In order to avoid the entry of foreign matter, it is usually necessary to set a sealing assembly covering the sound outlet. The sealing a...
