Abstract: Disclosed is a micro loudspeaker, which comprises a magnetic circuit system, a vibration system and a support system. The magnetic circuit system comprises a yoke, and a magnet and a washer accommodated within the yoke. The vibration system comprises a diaphragm and a voice coil adhesively fixed to the diaphragm. The support system comprises a front cover, and a housing matched and combined with the front cover. The housing comprises a bottom wall and a side wall. The bottom wall is provided with a mounting portion accommodating the magnetic circuit system, and is also provided with an assembly plane for assembly with a terminal. A height difference is provided between a position of the bottom wall of the housing corresponding to the assembly plane and a position of the side wall of the housing corresponding to the assembly plane, so as to cooperatively form an avoidance inclined surface.

Abstract: A loudspeaker module emitting sound at a lateral side comprises a loudspeaker unit and a module housing comprising a lower module housing, a middle module housing and an upper module housing. A space formed by the loudspeaker unit, the middle module housing and the lower module housing is a rear sound cavity. A space formed by the loudspeaker unit, the middle module housing and the upper module housing is a front sound cavity. The loudspeaker module further comprises a cover plate which forms a cavity together with the upper module housing. The cavity is communicated with the rear sound cavity through a conducting hole. By utilizing the loudspeaker module of the present invention, superfluous space of the upper module housing can be converted into the rear sound cavity, and therefore the size of the rear sound cavity is increased, and the acoustic performance of the loudspeaker module is improved.
