Problems solved by technology

[0003] The existing module shell basically adopts all-plastic or injection-molded steel sheet structure in plastic. In the case of a certain size, the volume of the rear cavity can only be increased by further reducing the thickness of the module shell. However, due to the The thickness of the shell should not be too thin, otherwise it will cause the box to resonate, which will lead to poor sound quality. Therefore, the volume of the rear cavity that can be increased by this method is very limited, and the acoustic performance of the speaker module cannot be significantly improved.

Abstract

The present invention discloses a module shell assembly, a loudspeaker module and an electronic device. The assembly includes a shell assembly body and at least one expansion board combined in the shell assembly body, and each expansion board is exposed through an inner surface of the shell assembly body, wherein the expansion board is a hard board, and the expansion board is made of a porous material. A module shell of the loudspeaker module includes the module shell assembly. The electronic device includes the loudspeaker module.

Description

technical field [0001] The present invention relates to the technical field of electro-acoustic products, more specifically, the present invention relates to a module shell assembly for a speaker module, a speaker module using the module shell assembly, and a speaker module provided with the speaker module Electronic equipment. Background technique [0002] The speaker module includes a module casing and a speaker unit installed in the module casing. In order to ensure that the speaker module has good acoustic performance, the module casing is usually required to have a larger rear cavity. [0003] The existing module shell basically adopts all-plastic or injection-molded steel sheet structure in plastic. In the case of a certain size, the volume of the rear cavity can only be increased by further reducing the thickness of the module shell. However, due to the The thickness of the shell should not be too thin, otherwise it will cause the box to resonate, resulting in poor s...
