 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例提供了一种扬声器模组100，结合图1和图2所示，用于设有出声口的移动终端，扬声器模组100包括扬声器箱1，扬声器箱1包括用于侧面发声的第一声音输出开口11和第二声音输出开口12，第一声音输出开口11和第二声音输出开口12分别设置于扬声器箱4的相对两个侧面；扬声器模组100还包括均呈中空且两端开口的第一号筒2和第二号筒3；第一号筒2的一端连接至扬声器箱1的侧面并与第一声音输出开口11连通，第一号筒2的另一端用于连接至移动终端的出声口；第二号筒3的一端连接至扬声器箱1的侧面并与第二声音输出开口12连通，第二号筒3的另一端用于连接至移动终端的出声口；第一号筒2与第二号筒3关于扬声器箱1呈非对称设置。
其中，第一号筒2与第二号筒3关于扬声器箱1呈非对称设置，即指代第一号筒2与第二号筒3的长度、尺寸、体积及造型不同。
本实施例中，第一号筒2和第二号筒3均为一个。当然，根据实际需求，第一号筒2和第二号筒3也可以均为多个，如两个、三个、四个、五个等。
本实施例中，扬声器箱1呈矩形，第一声音输出开口11和第二声音输出开口12分别设置于扬声器箱1的两个短轴边。当然，根据实际需求，扬声器箱1还可以设计成其它形状。
本实施例中，第一号筒2的谐振峰个数与其长度成正比。这样设计可以提升中频（1k-8kHz）响度。
本实施例中，第一号筒2包括与第一声音输出开口11连接的第一段21、由第一段21远离扬声器箱1的一端弯折延伸并与扬声器箱1间隔的第二段22以及由第二段22远离第一段21的一端延伸形成的第三段23，第三段23用于连接至移动终端的出声口。
本实施例中，第一段21沿第一方向呈90度弯折设置，第二段22沿第一方向的反方向呈180度弯折设置。这样设置可以在同等空间的前提下，加强了第一号筒2的长度，提升了空间利用率。
其中，第一方向为第一声音输出开口11的声音输出方向。
本实施例中，沿第一号筒2的出声方向，第三段23的横截面积逐渐变大。
本实施例中，第二号筒3包括与第二声音输出开口12连接且弯折设置的第四段31以及由第四段31远离扬声器箱1的一端弯折延伸并与扬声器箱1间隔的第五段32，第五段32用于连接至移动终端的出声口。通过将第二号筒3只设计成两段，可以在一定程度上减少扬声器模组100的占用空间。
本实施例中，沿第二号筒3的出声方向，第五段32的横截面积逐渐变大。
本实施例中，第一号筒2的第三段23以及第二号筒4的第五段42均延伸至超出扬声器箱1的长轴边所在的平面。
作为第一号筒2的另一种实施例，第一号筒2包括多个，多个第一号筒2的多个第一段21沿扬声器箱1的短轴方向并排设置，多个第一号筒2的多个第二段22沿扬声器箱1的厚度方向交错叠层设置，多个第一号筒2的多个第三段23沿扬声器箱1的长轴方向并排设置。
作为第二号筒3的另一种实施例，第二号筒3包括多个，多个第二号筒3的多个第四段31靠近扬声器箱1的部分沿扬声器箱1的短轴方向并排设置，多个第二号筒3的多个第四段31远离扬声器箱1的部分沿扬声器箱1的厚度方向交错叠层设置，多个第二号筒3的多个第五段32沿扬声器箱1的长轴方向并排设置。
作为第一号筒2和第二号筒3的一种具体实施例，第一号筒2为两个，第二号筒3也为两个。当然，根据实际需求，第一号筒2还可以是三个、四个、五个等，第二号筒3还可以是三个、四个、五个等。
与现有技术相比，本实施例中的扬声器模组100通过利用不同长度、尺寸、体积及造型的第一号筒2和第二号筒3完成了频响峰谷的补充，实现了谐振峰的多阶耦合，不仅提升了高频性能，还拓宽了频带范围，同时，由于无需填充吸音材料，还降低了扬声器模组100的制造成本。
另外，本实施例中的扬声器模组100还设计灵活，可适配移动终端中非对称的机壳，避让结构中的指定位置；图3为扬声器模组100中第一号筒2（Large horn）和第二号筒3（Small horn）的声功率（dB）曲线图，其单侧第二号筒3易在高频是出现坑谷，此时可利用第二号筒3进行峰谷补偿，匹配两者的曲线，图中的a用于表示Large horn声功率曲线，b用于表示Small horn声功率曲线；图4为扬声器模组100的声学性能测试结果示意图，从图中可知常规侧发声模组的测试结果曲线d在同一频率下的灵敏度均低于多级号角加出声口匹配模型的测试结果曲线c、初版2级号角的测试结果曲线e、初版2级号角加吸声材料的测试结果曲线f、多级变截面号角的测试结果曲线g、多级变截面号角加吸声材料的测试结果曲线h及大后腔模组正发声的测试结果曲线i的灵敏度，另外通过上述测试结果可知，与常规侧发声模组的发声相比，各类带号角的方案均具有高频频带的提升，其中，多级号角匹配加出声孔匹配模型的频带带宽和频响浮动均高于其它技术方案。
作为扬声器模组100的另一可选实施例，第二段22和/或第三段23和/或第五段32内填充有吸音材料。这样虽然会增加扬声器的制造成本，但却可以补充第一号筒2和/或第二号筒3的响应曲线，以提升扬声器模组100的高频性能。
图5为该扬声器模组100的声压级（SPL）曲线图，图中j表示ori的SPL曲线，k表示ori+resistance1100（内部阻抗1100Pa*s/m）+extend space（扩展空间）的SPL曲线，扬声器箱1横轴方向出声侧至移动终端的号筒在高频位置处产生坑谷时，可利用小腔体填充吸音材料增加号筒阻尼，以抹平高频SPL曲线；而逐渐增加体积，可以改变声容，进而实现对谐振频率点的控制。以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
