Abstract
A loudspeaker module comprises a housing and a loudspeaker unit. The housing is provided with an inner cavity for receiving and fixing the loudspeaker unit. A vibrating diaphragm of the loudspeaker unit partitions the inner cavity into a front sound cavity and a rear sound cavity. The front sound cavity is in communication with at least two sound uttering holes, and the at least two sound uttering holes are distributed on different sides of the housing. The electronic product comprises the loudspeaker module. By means of the technical solution of the present disclosure, the sound uttering holes are provided individually on different sides of a housing of a loudspeaker module. Due to the design of holes opened on at least two sides around the front cavity structure, the loudspeaker module having a side sound uttering structure reduces pipelines introduced during the implementation of the side sound uttering solution, and can achieve the effect of equivalently increasing the length of the sound uttering holes by increasing the number of the sound uttering holes, thereby extending the high-frequency characteristic of the electronic product having the loudspeaker module.
