具体的，所述导电端子5通过所述胶水贴合固定于所述支撑壁22并在所述断口410位置贴合固定于所述支架41。本实施方式中，所述支架41包括第一端部411、第二端部412以及连接所述第一端部411和第二端部412的连接部413，所述第一端部411和第二端部412之间形成所述断口410，所述第一端部411靠近所述连接部413的一端高于所述第一端部411靠近所述第二端部412的一端。当然，同理，也可以设置为所述第二端部412靠近所述连接部4的一端高于所述第二端部412靠近所述第一端部411的一端。也就是说，所述断口420沿所述支架41延伸的方向远离所述支撑壁22的一侧的距离大于靠近所述支撑壁22的一侧的距离。本实施方式中，所述断口410沿所述透气隔离件42向所述支撑壁22的方向呈倒梯形。该结构使得胶水从所述断口420远离所述支撑壁22的一侧流入将所述导电端子5密封固定，有利于组装，并提高了可靠性。
与相关技术相比，本实用新型的扬声器箱将所述发声单体和所述透气隔离组件分别支撑固定于所述支撑壁以共同将所述收容空间分隔成前腔和后腔，透气隔离组件设有分别环绕所述发声单体的周侧的支架和透气隔离件，支架设有断口，导电端子卡设于断口并夹设固定于支撑壁与透气隔离件之间，导电端子经断口及后腔延伸至收容空间外；透气隔离组件完全覆盖泄漏孔并将吸音颗粒封装于后腔内。上述结构则使得透气隔离组件远离所述发声单体一侧的后腔内填充吸音颗粒后全部作为虚拟声腔，有效提高了扬声器箱的低频声学性能；因透气隔离组件绕设固定于发声单体，极大程度的提高了后腔的体积，从而有效提高了后腔内的吸音颗粒的灌装效率。
以上所述仅为本实用新型的实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本实用新型的专利保护范围内。
