Problems solved by technology

[0004] However, the existing resonant cavity is a single cavity, which is limited by the singleness of the natural frequency. The resonant cavity has a limited frequency adjustment width, and cannot effectively adjust the position of the frequency response curve with multiple peaks and valleys, and the frequency response curve is not smooth.

Abstract

Disclosed are a loudspeaker module and an electronic device. The module comprises a module housing and a loudspeaker monomer; an accommodating cavity and a plurality of resonant cavities are formed in the module housing; the loudspeaker monomer is provided in the accommodating cavity, and separates the accommodating cavity into a front acoustic cavity and a rear acoustic cavity; the front acoustic cavity is communicated with an external space by means of a sound outlet; at least two of the plurality of resonant cavities are communicated in series, and at least two resonant cavities are provided in parallel; one of the resonant cavities communicated in series is communicated with the front acoustic cavity; the resonant cavities provided in parallel are isolated from each other, and are communicated with the front acoustic cavity, separately. In the present invention, by enabling the resonant cavities to be provided in parallel and in series, the sound production effect of the loudspeaker module can be improved.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products. More specifically, it relates to a speaker module and electronic equipment. Background technique [0002] The loudspeaker is an important acoustic component in electronic equipment, and it is a transducer device that converts electrical signals into acoustic signals. The existing loudspeaker module includes a casing, and a sound generator unit arranged in the casing, and the sound generator unit divides the accommodating cavity in the casing into a front sound cavity and a rear sound cavity. The front cavity has little effect on the low-frequency band of the music sound, but mainly affects the high-frequency part. [0003] In the existing speaker modules, especially for the modules with side sound outlets, because the sound outlet channel of the front cavity is long, it is easy to cause high-frequency resonance, thereby affecting the acoustic performance of the speaker module, ...
