Title
(EN) Loudspeaker module
(ZH) 扬声器模组
Abstract
(EN) The invention provides a loudspeaker module, which comprises a shell with an accommodating space, and a sound production assembly and a breathable separator which are accommodated and fixed in the shell, wherein the shell comprises a bottom wall and a top wall which are oppositely arranged at an interval, and a side wall which is bent and extends from the bottom wall to the top wall; the bottom wall, the side wall and the top wall enclose the accommodating space; a retaining wall is convexly arranged on one side, close to the top wall, of the bottom wall towards the top wall; the breathable isolation part is injection-molded at one end, close to the top wall, of the retaining wall and divides the accommodating space into an accommodating cavity for accommodating the sound production assembly and a sound absorption cavity for accommodating the sound absorption material; the breathable isolation part, the retaining wall and the bottom wall define an accommodating cavity; the sound absorption cavity is located between the breathable isolation part; the sound production assembly comprises a sound production single body and a support for accommodating and fixing the sound production single body, the sound production single body is provided with a vibrating diaphragm deviating from the top wall, a mounting hole is formed in the bottom wall in a penetrating mode, and the support is fixed to the shell through the mounting hole and fixes the sound production single body between the bottom wall and the breathable isolation piece. The assembly is convenient, and the acoustic performance is improved.
(ZH) 本发明提供了扬声器模组,包括具有收容空间的壳体以及收容固定于壳体的发声组件和透气隔离件,壳体包括相对且间隔设置的底壁与顶壁、以及自底壁朝顶壁弯折延伸的侧壁,底壁、侧壁及顶壁围成收容空间;底壁靠近顶壁的一侧朝顶壁方向凸设有挡墙,透气隔离件注塑在挡墙靠近顶壁的一端并将收容空间分割成收容发声组件的容纳腔以及收容吸音材料的吸音腔,透气隔离件、挡墙及底壁围合形成容纳腔,吸音腔位于透气隔离件与顶壁之间;发声组件包括发声单体以及收容并固定发声单体的支架,发声单体具有背离顶壁的振膜,底壁贯穿开设有安装孔,支架经安装孔固定于壳体并将发声单体固定于底壁与透气隔离件之间。不仅便于装配,而且提高了声学性能。
