Title
(EN) Loudspeaker module
(ZH) 扬声器模组
Abstract
(EN)
A loudspeaker module includes a module housing forming an accommodation space, and a loudspeaker unit provided in the accommodation space, a loudspeaker unit divide the accommodating space into a front acoustic chamber and a rear acoustic chamber, the module housing is provided with an acoustic outlet hole communicated with the front acoustic cavity, an outer surface of the module housing near thesound outlet hole is fixedly coupled with a fixing portion, the loudspeaker module further comprises an annular separating sound hole, wherein the separating sound hole protrudes outwardly from one side surface of the module housing to form a plugging portion, the plugging portion has an outer shape corresponding to the inner side surface of the sound outlet hole, the plugging portion and the sound outlet hole are arranged to be interference fit, and the separating sound hole is fixedly bonded to the surface of the fixing portion. The structure makes the bending force generated by the separating sound hole be borne by the shell during the drop test, and reduces the separating force generated between the separating sound hole and the fixed part, so the cracks are not easily generated between the separating sound hole and the shell, thus causing the separating sound hole to fall off from the shell, and improving the reliability of the product.

本发明公开一种扬声器模组,包括形成容纳空间的模组壳体,以及设置在容纳空间中的扬声器单体,扬声器单体将容纳空间分隔为前声腔和后声腔,模组壳体开设有与前声腔连通的出声孔,靠近出声孔处的模组壳体外侧表面固定结合有固定部,该扬声器模组还包括环形的分离声孔,分离声孔靠近模组壳体的一侧表面向外凸起形成插接部,插接部具有与出声孔的内侧表面匹配对应的外形,插接部与出声孔设置为过盈配合,且分离声孔固定结合于固定部的表面。此种结构使得跌落测试时,分离声孔产生的弯折力由壳体承担,减少分离声孔与固定部之间产生分离力,从而不易在分离声孔与壳体之间产生裂缝,造成分离声孔从壳体上脱落,提高了本产品的可靠性。
