Title
(EN) Loudspeaker module
(ZH) 扬声器模组
Abstract
(EN) The utility model provides a loudspeaker module group. The loudspeaker module group comprises a support, a cover body which covers the support and forms a cavity with the support, a ventilating separator accommodated in the cavity, and a sound production single body accommodated in the cavity. The cavity is divided into a containing cavity and a sound absorption cavity by the breathable isolation piece, the breathable isolation piece covers the sound production single body and is enclosed with the support to form the containing cavity, a supporting rib protruding and extending towards the breathable isolation piece is arranged on the side, close to the breathable isolation piece, of the sound production single body, and the breathable isolation piece abuts against the supporting rib. The cavity is divided into the containing cavity and the sound absorption cavity through the breathable isolation piece, the sound production single body is placed in the containing cavity, the supporting ribs are arranged on the sound production single body, the breathable isolation piece abuts against the supporting ribs, and the breathable isolation piece is supported by the supporting ribs, so that the breathable isolation piece can be prevented from being attached to the surface of the sound production single body due to deformation; and therefore, the acoustic performance of the loudspeaker module can be prevented from being influenced by the deformation of the breathable isolation piece.
(ZH) 本实用新型提供了扬声器模组,扬声器模组包括支架、盖设在支架上并与支架围合形成腔体的盖体、收容于腔体内的透气隔离件以及收容于腔体内的发声单体;透气隔离件将腔体分隔为容纳腔和吸音腔,透气隔离件盖设于发声单体并与支架围合形成容纳腔,发声单体上靠近透气隔离件的一侧设置有向透气隔离件凸出延伸的支撑筋,透气隔离件抵压在支撑筋上。通过透气隔离件将腔体分隔为容纳腔和吸音腔,发声单体放置在容纳腔内,发声单体上设置有支撑筋,而透气隔离件抵压在支撑筋上,通过支撑筋对透气隔离件的支撑,可以防止透气隔离件因变形而贴在发声单体的表面,进而可以防止因透气隔离件的变形而影响扬声器模组的声学性能。
