A speaker module and electronic equipment

Abstract

The invention discloses a loudspeaker module, which comprises a housing with a receiving cavity and a sounding unit accommodated in the receiving cavity, and the sounding unit divides the receiving cavity into a front cavity and a rear cavity; the casing includes a lower A shell and an upper shell, the upper shell includes a first body portion and a first partition wall protruding from the first body portion, the lower shell includes a second body portion and a partition wall protruding from the second body portion The second partition wall, the first partition wall and the second partition wall are butted and inserted, and the rear cavity is divided into a first rear cavity and a second rear cavity, and the second rear cavity is filled with sound-absorbing particles; An air-permeable isolation channel is formed between the end surfaces of the first isolation wall and the second isolation wall, and the width of the air-permeable isolation channel is smaller than the diameter of the sound-absorbing particles. The processing and assembly of isolation components in the traditional design are omitted, the manufacturing process is relatively simple, and the processing cost is reduced; the assembly process is reduced, the difficulty is reduced, and the assembly efficiency and yield rate are significantly 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
