speaker module

Abstract

The invention discloses a loudspeaker module which comprises a shell and a loudspeaker body fixedly contained in the shell. A sound outgoing hole corresponding to the loudspeaker body is formed in the shell and used for outgoing of sound. A shielding part is arranged at the position, corresponding to the sound outgoing hole, inside the shell. The shielding part covers the sound outgoing hole and is of a nonmetal net structure. The shielding part of the nonmetal net structure and the shell are integrally formed in an injection molding mode. The loudspeaker module has the advantages of being good in acoustic performance, high in reliability, good in space use ratio and high in production efficiency.

Description

Technical field [0001] The invention relates to the field of electroacoustics, in particular to a speaker module. Background technique [0002] With the expansion of the consumer electronics market, a large number of consumer electronic products such as mobile phones and notebook computers have been widely used. As an important acoustic component in consumer electronic products, speaker modules have a wide range of needs. As people's requirements for consumer electronic products increase, the performance of speaker modules has attracted more and more attention. [0003] The speaker module includes a housing for accommodating a speaker unit fixed in the housing. The housing is provided with a sound outlet corresponding to the speaker unit for sound emission, and the sound emitted by the speaker unit is transmitted from the sound outlet to the speaker Outside the module. In order to improve the waterproof and dustproof performance of the module, while adjusting the acoustic perform...

AI Technical Summary

Problems solved by technology

The damping mesh made of metal material has a large thickness and a large mesh aperture, which has poor waterproof and dustproof effect and is prone to rust, which will adversely affect the performance of the speaker module

Moreover, the metal material will increase the metal area of ​​the module, which will affect some parts of the end product

[0004] For other non-metallic damping meshes, during the assembly process, the damping cloth or metal mesh is usually pasted on the position of the sound hole by manual or automatic pasting. When pasting by hand, the positioning of the damping material is poor and the assembly efficiency is low. , automatic paste increases the production cost of the module; the damping material pasted at the position of the sound outlet affects the appearance of the product and increases the volume of the speaker module; therefore, it is necessary to provide an improvement to overcome the defects of the prior art speaker module
