Abstract: Disclosed is a loudspeaker, comprising a casing (7) and a vibration system. The vibration system comprises a vibrating diaphragm (3) and a sound coil (4) fixed at a side of the vibrating diaphragm. A joint portion is arranged at an edge of the vibrating diaphragm (3). The joint portion is bonded and fixed to the casing (7). A recessed adhesive accommodating structure (71) is arranged at an end face connecting the casing (7) to the joint portion. The adhesive accommodating structure (71) is arranged corresponding to an adhesive surface between the vibrating diaphragm (3) and the casing (7), and is an annular structure. According to the present invention, the loudspeaker's acoustic performance is stabilized, while the vibrating diaphragm (3) and the casing (7) can be firmly connected to each other.

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.
