如图3所示，为了不占用竖直空间，本实施例扬声器模组的第一壳体11侧面设置有出声孔11b，第一壳体11与扬声器单体2围成前声腔，出声孔11b与前声腔连通，扬声器单体2发出的声音从出声孔11b传递至外部环境。为了避免外部异物进入扬声器某种内部对扬声器正常工作造成影响，第一壳体11侧面对应出声孔11b位置设置有防尘网4，防尘网4可以进一步提高扬声器模组可靠性。As shown in FIG. 3, in order to not occupy the vertical space, the sound emitting hole 11b is disposed on the side of the first housing 11 of the speaker module of the embodiment, and the first housing 11 and the speaker unit 2 enclose the front sound chamber. The hole 11b communicates with the front sound chamber, and the sound emitted from the speaker unit 2 is transmitted from the sound hole 11b to the external environment. In order to prevent external foreign matter from entering the interior of the speaker and affecting the normal operation of the speaker, the side of the first housing 11 is provided with a dustproof net 4 corresponding to the sound hole 11b. The dustproof net 4 can further improve the reliability of the speaker module.
综上，本发明扬声器模组具有可靠性高的优点。In summary, the speaker module of the present invention has the advantage of high reliability.
