Loudspeaker module and electronic equipment

Abstract

The invention discloses a loudspeaker module, which comprises a shell with an accommodating cavity and a sound production unit accommodated in the accommodating cavity, and is characterized in that the accommodating cavity is divided into a front cavity and a rear cavity by the sound production unit; the shell comprises a lower shell body and an upper shell body, the upper shell body comprises a first body part and a first isolation wall arranged on the first body part in a protruding mode, the lower shell body comprises a second body part and a second isolation wall arranged on the second body part in a protruding mode, and the first isolation wall and the second isolation wall are inserted in a butt joint mode. The rear cavity is divided into a first rear cavity and a second rear cavity,and the second rear cavity is filled with sound absorption particles; a breathable isolation channel is formed between the end faces of the first isolation wall and the second isolation wall, and thewidth of the breathable isolation channel is smaller than the diameter of the sound absorption particles. Processing and assembling of an isolation assembly in traditional design are omitted, the manufacturing process is simple, and the processing cost is reduced; the assembling procedures are reduced, the difficulty is reduced, and the assembling efficiency and the yield are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a loudspeaker module and electronic equipment. Background technique [0002] With social and economic development and consumption upgrades, consumers have put forward higher requirements for the sound quality of electronic equipment, which requires more space for the sound cavity design of speaker modules, but the contradiction is that consumers have higher requirements for some electronic equipment. The portability requirements of the equipment are getting higher and higher, and the expansion of the sound chamber space is limited, and even further compression of the space is required. [0003] In order to expand the volume of the sound cavity, reduce the low frequency of the module, and expand the bandwidth, sound-absorbing particles are generally filled in the rear cavity of the module. In order to prevent the sound-absorbing particles from entering the speak...

Problems solved by technology

However, the isolation component is made of the isolation net and the isolation frame by insert injection molding. When the isolation net is used as an insert and the isolation frame is injection molded, on the one hand, the process is relatively complicated, the mold cost is high, and the yield rate is low. On the other hand, the assembly process cumbersome and less efficient
