Abstract

The invention discloses a loudspeaker module and an electronic device. The module comprises a module shell and a sound production device. A containing cavity and a plurality of resonant cavities are arranged in the module shell. The sound production device is arranged in the containing cavity. The containing cavity is divided into a front sound cavity and a rear sound cavity by the sound production device. The front sound cavity communicates with an external space through a sound outlet. The plurality of resonant cavities are mutually isolated. Each resonant cavity communicates with the front sound cavity of the module shell through a respective communication channel. Through application of the mode, the sound production effect of the loudspeaker module can be improved by the plurality of resonant cavities which are arranged in parallel.

Description

technical field [0001] The present invention relates to the technical field of electroacoustic conversion, and more specifically, to a loudspeaker module and electronic equipment. Background technique [0002] In existing speaker modules, in order to reduce noise, a sealed resonant cavity is usually provided on the module casing. The resonance cavity communicates with the front acoustic cavity. The resonance cavity has a significant improvement on the speaker module FR. [0003] However, the existing resonant cavity is a single cavity. Limited by the singleness of the natural frequency, the resonant cavity has a limited adjustment frequency width and cannot effectively absorb noise in a wider frequency band. [0004] In addition, a single cavity has less transmission loss in the set frequency band. Contents of the invention [0005] An object of the present invention is to provide a new technical solution for a loudspeaker module. [0006] According to a first aspect ...
