本实施例中，所述卷簧41的第一端411位于卷簧41外周缘，所述第二端412位于卷簧41内环中。所述转体29为与卷轴20同轴的圆盘，所述转体29套于所述卷轴20的一转轴26上并与所述转轴26固定。所述棘轮42设有与轴线垂直的侧面，所述棘轮42的侧面贴于所述转体29的端面上并与所述卷轴20同轴。所述棘轮42的轮齿421为相对轴线同向倾斜的斜齿，本实施例中，轮齿421为顺时针方向倾斜。每一轮齿421包括止挡面422及与止挡面422夹角连接的引导斜面423。所述限位片43为塑料材质制成，具有回弹性。限位片43竖直向上延伸并具有靠近棘轮42的竖直侧面及水平顶面。当拉动柔性显示屏30伸展时，卷轴20在柔性显示屏30的带动下沿逆时针旋转，棘轮42在卷轴20的带动下也一同逆时针旋转。棘轮42在逆时针旋转时，其各引导斜面423将逐个抵接限位片43的竖直侧面，从而引导棘轮42的旋转。一旦停止拉动输入装置主体30，棘轮42的止挡面422将抵接限位片43的水平顶面，从而将棘轮42进行限位。并且，在拉伸输入装置主体30的过程中，卷簧41被拉伸而产生回弹力。当需要释放柔性显示屏30时，通过按钮45按压所述限位片43发生倾斜，使水平顶面与所述止挡面422分离进而释放棘轮42。在卷簧41的回弹力作用下，棘轮42及卷轴20发生顺时针旋转，从而自动将柔性显示屏30收拢。当释放按压按钮45后，所述限位片43回位，再度通过其水平顶面抵接棘轮42的止挡面422，从而对棘轮42限位，阻止输入装置主体30收拢。如此，可以通过选择性地松开按钮45使柔性显示屏30伸展至任一位置。本实施例中，所述止挡面422均位于棘轮42的径向上。
本实施例中，所述卷轴20释放所述柔性显示屏30，所述棘轮逆时针旋转，所述卷簧41发生弹性形变储蓄弹性势能，所述卷轴20回收柔性显示屏30的转动方向为顺时针，所述限位片43与所述轮齿421解锁，所述卷簧41释放弹性势能产生回弹力而使卷轴20转动，进而收回所述柔性显示屏30。而且由于卷轴20内部装有电池及电路板，会增加卷轴20的重量，在卷簧41回弹时会减小回弹力，卷轴20回转的速度降低，可以避免拉坏所述柔性显示屏30。本发明所述的驱动部仅通过棘轮42及限位片43即可实现卷轴20卷收及释放按 键本体30以及对卷轴20的锁持，结构简单，节省卷筒10的空间便于操作。

本实施例中，所述第一壳体11上位于端口位置设有第一开口槽121，位于所述第一腔体的第一端槽116内，并且所述第一开口槽121与所述第一端槽116共同有一个槽壁，即所述的第一竖板118。第一壳体11上还形成与第一竖板118连接的竖直的间隔板1115。间隔板1115的一段垂直于第一竖板118，另一端垂直于外端板15，且间隔板1115连接第一竖板118及外端板15。间隔板、第一竖板118、外端板15及弧形面111共同围设形成第一腔室的下部， 即第一开口槽121。相应的所述第二壳体13上位于所述端口位置设有第二开口槽122，位于构成所述第一腔体的第二端槽136内。第二开口槽122与第二端槽136有共同的槽壁，也就是所述第二竖板138。第二壳体亦形成垂直连接第二竖板138的间隔板1315。间隔板1315、第二竖板138、及弧形面131共同围设形成第一腔室的上部，即第二开口槽122，其与第一开口槽121连通而组成第一腔室。换句话说，所述第一开口槽121与所述第二开口槽122配合，所述外端板15遮蔽所述第二开口槽122的侧面开口，进而形成所述第一腔室。间隔板将位于第一腔室内的第一扬声器70与驱动部隔开。
进一步的，所述第一腔室内设有两个相对的定位块(图未标)，所述第一扬声器70夹持于所述两个定位块之间。所述第一开口槽121内相对于第二开口槽122的槽壁上凸设有凸台(图未标)，用于辅助所述第一扬声器70装于所述第一腔室内的定位。
请参阅图11，进一步的，所述端盖17上设有收容第二扬声器80的第二腔室(图未标)及第二出音孔区82。所述第二扬声器80的发音位置朝向所述第二出音孔区82，所述第二出音孔区82与所述第二腔室连通。本实施例中，所述底板171上有挡板177。所述挡板177连接所述底板171及周板172并围成一槽体178，所述第二出音孔区82设于构成所述槽体178部分的周板172上，所述端盖17还包括挡片175，所述挡片175朝向第二腔室172内的表面凸设有止挡片1751，所述挡片175盖于所述槽体178上形成所述第二腔室，所述止挡片1751伸入所述第二腔室内将所述第二扬声器80抵持以定位于所述第二腔室172内。所述挡片175的一侧边上设有缺口1752，所述缺口1752便于第二扬声器80的导线穿过。挡片175平行于底板171，止挡片2751垂直于底板171。
第一扬声器70通过穿过棘轮42中心通孔及转轴26的穿孔的导线与卷轴20内的电路板60电连接。电路板60通过穿过隔板213的开槽的导线与电池50电连接。电池50通过穿过转轴26的穿孔的导线而与线路板92电连接。线路板92通过穿过缺口1752的导线与第二扬声器80连接。由此，整个卷筒10内形成完整的电流回路。
本发明的所述扬声器70、80可以外音播放使用柔性显示屏30的电子装置200的音频。第一出音孔区152与所述第二出音孔区82朝向不同，而且第一 扬声器70及第二扬声器80位于所述卷筒10的两端，因此可以实现第一扬声器70沿轴向朝侧面发音，而第二扬声器80沿径向朝垂直卷筒10轴向方向(即朝向用户的方向)发音，提高卷筒10的发音面积及效果。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
