为了使本领域技术人员更好的理解本申请的技术方案，下面结合说明书附图对本申请实施例进行详细的描述。
一方面，本申请实施例提供了一种扬声器组件；如图1所示，扬声器组件包括第一壳体1、第二壳体2、扬声器振子3及调节机构；第一壳体1(的一部分)与扬声器振子3围成第一腔体，第二壳体2(的一部分)与扬声器振子3围成第二腔体；调节机构包括驱动机构4及填充部件5；驱动机构4能够驱动填充部件5运动以改变填充部件5探入第二腔体内的体积，以降低或增大第二腔体的体积大小。

进一步的，如图1至图3所示，在本申请提供的实施例中，驱动机构4包括驱动电机41及传动组件，填充部件5为滑块51；驱动电机41通过传动组件与滑块51传动连接；第二壳体2具有限定滑块51往复滑动的滑孔(图中未示出)；其中，传动机构能够将驱动电机41的旋转运动转化为直线运动，以带动滑块51沿直线方向滑动。
具体的，如图2所示，在第一实施例中，传动组件可以为丝杠螺母机构；其中，驱动电机41的输出轴42上设有螺纹(图中未示出)，滑块51上设有与输出轴42螺接的螺纹孔52；驱动电机41的输出轴42旋转以带动滑块51滑动。其中，滑块51为矩形的块状，滑孔(图中未示出)为与滑块51相对应的矩形孔，滑块51与滑孔密闭式接触；这种结构设置不仅能够保证在驱动电机41旋转时，滑块51能够沿滑孔部分地滑入、滑出第二腔体，还能保证第二腔体的密闭性；其中，为了进一步提升第二腔体的密闭性，滑块51上的螺纹孔52为盲孔。
当然，在其他实施例中，滑块51还可以为其他的形状构造，例如，滑块51的截面形 状还可以为三角形、六边形等多边形结构；相应的，滑孔的截面形状应为与滑块51的截面形状相对应的三角形、六边形等结构；本实施例对此不作具体限定。
进一步的，如图3所示，在第二实施例中，传动组件还可以为齿轮齿条机构；其中，齿轮6套设在驱动电机41的输出轴42上，齿条7与滑块51连接，驱动电机41驱动齿轮6转动以带动齿条7和滑块51移动。其中，滑块51为矩形的块状，滑孔为与滑块51相对应的矩形孔，滑块51与滑孔密闭式接触，以保证第二腔体的密闭性；其中，在滑块51本体上也可以设置齿条形结构能够与齿轮6进行啮合，但为了降低制作成本，同时也为了保证第二腔体的密闭性，在本实施例中，滑块51与制作成型的齿条7固定连接，以通过齿条7与齿轮6的啮合来带动滑块51滑动。
当然，在其他实施例中，滑块51还可以为其他的形状构造，例如，滑块51的截面形状还可以为圆形、三角形、六边形等结构；相应的，滑孔的截面形状应为与滑块51的截面形状相对应的圆形、三角形、六边形等结构；本实施例对此不作具体限定。
其中，第一壳体1和第二壳体2的材质可以为塑料(如聚乙烯、聚氯乙烯)，滑块51的材质也可以为塑料，当然，为了增加滑块51的响应速度，可选轻质的材料来制作滑块51。

为了进一步提升音效品质，本实施例中，电子设备还包括音频采集模块；音频采集模块能够采集待播放音频信息的频率信息；控制器能够根据所述频率信息控制驱动机构4的供断电状态。
具体的，以智能手机为例，当用户在播放某一首音乐时，音频采集模块采集该首音乐的音频信息中的频率信息，控制器根据该频率信息来控制驱动机构4的供断电状态，进而控制第二腔体的体积大小。其中，在音乐播放过程中的某一时间点内可控制第二腔体的体积增加，在下一时间点内控制第二腔体的体积减小；本领域技术人员可对其具体控制逻辑及实现的播放效果作相应调整，本实施例对此不作具体限定。
