本申请基于申请号为201910210093.3、申请日为2019年3月19日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及显示设备技术领域，具体涉及一种音箱结构及显示设备。
背景技术
目前电视音箱的出声一般分为朝前出声音、朝下出声音、朝后出声音三种方案，当中音质最好的是朝前出声音、其次是朝下出声音、音质最差的是朝后出声音。为了追求优质的音质效果，一般需要电视朝前出声音，但是在朝前出声音的方案中，音箱需在屏幕下面占据较大空间，无法获得具备简洁外观的电视
为此，现有的相关产品中出现了一些可以通过改变音箱的位置而实现能够调整出声方向的方案，这些方案一般集中在以下两种形式：
一、上下运动式，这种方式的音箱安装在电视的后壳内，其通过驱动音箱上下运动来实现朝前出声音；
二、组合运动式，这种方式的音箱也安装在电视的后壳内，其先通过驱动音箱上下运动，再驱动音箱倾斜或朝前运动来实现朝前出声音。
在上述第一种形式中，由于伸出的音箱与显示屏的显示面还有较大距离，外观效果不好。在上述第二种形式中，虽然能够将音箱驱动到与显示面齐平，但是驱动机构由于需要完成两种运动，使得驱动机构的体型较大，这种驱动机构都需要布置在整机内部，而为了容纳该驱动机构，会导致电 视整机的上半部分体型较大，外观不简洁、不美观，同时当音箱移开后，音箱原来所在的空间也变成空洞，这部分空洞可以伸入手指，或异物容易进入，不安全、不可靠。

实施例
本实施例提供了一种显示设备。
请参考图1-5，该显示设备包括显示屏1000和音箱结构2000，显示屏1000的背部设有容置腔1100，音箱结构2000安装在容置腔1100内，该音箱结构2000能够在容置腔1100内进行竖直方向上的往复运动和水平方向的往复运动，最终使得音箱结构2000处于显示屏1000的正下方并与显示屏1000的显示面齐平。
请结合参考图6-8，该音箱结构2000包括主音箱100、副音箱200、第一驱动机构300和第二驱动机构400。
其中，副音箱200以可相对于主音箱100发生位移的方式与主音箱100相连。第一驱动机构300用于驱动主音箱100沿第一方向往复运动。第二驱动机构400用于驱动副音箱200相对于主音箱100沿第二方向往复运动，第一驱动机构300内置于主音箱100内，第二驱动机构400内置于主音箱100内，且第二驱动机构400的输出端伸出主音箱100，副音箱200与输出端相连。
如此，由于该音箱结构2000包括主音箱100和副音箱200，并且该副音箱200以可相对于主音箱100发生位移的方式与主音箱100相连，使得主音箱100和副音箱200能够在第一驱动机构300的驱动下同时沿第一方向往复运动，副音箱200能够在第二驱动机构400的驱动下沿第二方向往复运动，通过上述两个运动方向的结合能够最终使得副音箱200与显示设备的显示面齐平，保证了显示设备的外观效果。同时，第一驱动机构300和第二驱动机构400仅需各自完成一个方向上的往复运动，可使得第一驱动机构300和第二驱动机构400在结构上更加小巧、紧凑，无需占据较多的安装空间，从而使得第一驱动机构300和第二驱动机构400均能够内置于主音箱100内，此时可将第一驱动机构300、第二驱动机构400在结构与主音箱100、副音箱200形成模块化设计，安装和维修方便，且能够进一步 提升外观效果。
需要说明的是，本申请实施方式中的音箱结构2000可以应用到诸如电视等显示设备中，此时第一方向可理解成竖直方向，第二方向可理解成水平方向。另外，该音箱结构2000也可以单独使用，例如它可以使用在一些仅需要发声的场合，在不需要发声时，该音箱结构2000隐藏收纳起来，在需要发声时，该音箱结构2000再伸出以朝前发声。
本文主要从音箱结构2000在显示设备中的应用为了进行说明，也就是说在下文的相关描述中，第一方向可理解成竖直方向，第二方向可理解成水平方向。
另外，在某些实施例中，第一驱动机构300与第二驱动机构400平行设置，可以进一步合理利用主音箱100的空间，从而进一步提升整个显示设备的外观效果。而为了使得第一驱动机构300和第二驱动机构400能够平行设置，第一驱动机构300和第二驱动机构400可以采用以下的示例结构，但应当理解，第一驱动机构300和第二驱动机构400不限于以下示例结构。
请参考图7，在一种实施例中，主音箱100包括主壳体110及发音单元，主壳体110限定出主腔体，发音单元设置在主腔体内。
发音单元可采用现有的任一种元器件来实现，例如发音单元可以是喇叭，也可以是扬声器，还可以是喇叭和扬声器的组合等。
请结合参考图7-9，主音箱100还包括具有沿第一方向导向的限位槽121的支架120，支架120固定安装在主壳体110内，并与主壳体110围成安装腔，第一驱动机构300包括限位件310及第一驱动组件，限位件310的一侧穿过主壳体110并固定安装，另一侧具有与限位槽121配合的凸起311，第一驱动组件安装在安装腔内，第一驱动组件沿第一方向布置，且能够输出旋转运动，限位件310安装在第一驱动组件的输出端，其与第一驱动组 件之间发生相对转动而使其能够相对支架120而沿着限位槽121移动。
可以理解的是，在上述安装关系中，由于限位件310的一侧是固定设置的，也就是说限位件310与支架120之间的相对移动实质上是指支架120的移动。具体来说，支架120是固定安装在主壳体110内的，第一驱动组件又是安装在支架120上的，此时支架120、第一驱动组件和主壳体110将会一起移动。限位件310是安装在能够输出旋转运动的第一驱动组件的输出端的，按理说限位件310将会跟随第一驱动组件做旋转运动，但是由于限位件310受到限位槽121的周向限制作用，从而使得第一驱动组件能够相对于限位件310沿第一方向移动，继而使得支架120和主壳体110一起随着第一驱动组件而移动，最终使得主音箱100和副音箱200能够相对显示屏1000而在竖直方向上移动。
更具体地说，第一驱动组件包括第一驱动电机320、齿轮组件330及丝杠340，第一驱动电机320与丝杠340平行布置，齿轮组件330连接在第一驱动电机320和丝杠340的同一端，限位件310套设在丝杠340上。
此时可以知道的是，当启动第一驱动电机320正转时(或者反转)，第一驱动电机320将会通过齿轮组件330而带动丝杠340转动，由于限位件310是固定设置的，丝杠340在转动的过程中就会相对于限位件310发生位移，最终使得整个第一驱动组件产生移动，当启动第一驱动电机320反转时(或者正转)，第一驱动组件将会反向移动，从而实现了主音箱100和副音箱200沿第一方向的往复运动。
为了规范主音箱100和副音箱200在第一方向上的运动路线，主音箱100还包括第一挡光件130、第一控制板140及设置在第一控制板140上的第一位置传感器150和第二位置传感器160。第一挡光件130与限位件310固定连接，第一控制板140固定安装在主壳体110上，第一位置传感器150、第二位置传感器160沿第一方向间隔布置，第一位置传感器150和第二位 置传感器160分别与第一挡光件130配合以限制支架120(或主壳体110、第一控制板140)的极限位置，从而限制主音箱100和副音箱200的极限位置。
由于第一控制板140固定安装在主壳体110上，此时第一控制板140将会随主壳体110一起移动，在第一控制板140的移动过程中，第一位置传感器150和第二位置传感器160将会交替被第一挡光件130所阻挡，使得第一位置传感器150和第二位置传感器160分别发送信号，以控制第一控制板140的极限位置，也就控制了主壳体110、支架120，乃至主音箱100和副音箱200的极限位置。
在本申请实施例中，将第一位置传感器150设置在下方，将第二位置传感器160设置在上方，当主音箱100和副音箱200未沿第一方向移动时，第一挡光件130处于丝杠340的最下方，并与第一位置传感器150相对应，此时显示设备处于关机状态。一旦显示设备开机产生开机信号，第一驱动电机320即开始运转，最终使得丝杠340往下移动，直至第一挡光件130移动到与第二位置传感器160相对应，接着再通过第二驱动机构400驱动副音箱200沿第二方向移动即可最终使得副音箱200处于显示屏1000的正下方，并与显示屏1000的显示面齐平。
为了避免对副音箱200的移动造成干扰，主音箱100在第一驱动机构300的驱动下宜移动到超过显示屏1000的最下方，使得副音箱200与显示屏1000之间具有一定的间隙(如图10所示)，而为了提高显示设备的外观效果，该间隙在副音箱200移动到位后又应当消除(如图11所示)。
对此，请参考图12，本申请在第一位置传感器150和第二位置传感器160之间还设有第三位置传感器170，该第三位置传感器170靠近第二位置传感器160而设置，并且第三位置传感器170与第二位置传感器160之间的距离与前述间隙相匹配。
此时，在检测到副音箱200移动到位后，第一驱动电机320反转使得第一挡光件130移动到与第三位置传感器170相对应的位置处，此时对主音箱100和副音箱200来说，就向上移动了一定的距离，从而消除了副音箱200与显示屏1000之间的间隙。
请结合参考图6-7，在一种实施例中，副音箱200包括副壳体210及发音单元，副壳体210限定出副腔体，发音单元设置在副腔体内，第二驱动机构400包括第二驱动电机410及齿轮齿条组件420，第二驱动电机410设置在主腔体内，其输出端伸入到副腔体，齿轮齿条组件420连接于第二驱动电机410的输出端，齿轮齿条组件420中的齿条沿第二方向布置。
在第一驱动机构300驱动主音箱100和副音箱200移动到第一挡光件130与第二位置传感器160相对应时，第二驱动机构400中的第二驱动电机410即可开始运转，使得齿轮齿条组件420动作，此时第二驱动电机410在第一方向上是固定的，而齿条沿第二方向布置，从而使得齿条能够相对于齿轮沿第二方向移动，而齿轮齿条组件420中的齿条是与副壳体210固定连接的，最终使得副音箱200沿第二方向移动。
请参考图7及图13，为了规范副音箱200在第二方向上的运动路线，副音箱200还包括第二挡光件220、第二控制板230及设置在第二控制板230上的第四位置传感器240和第五位置传感器250，该第二控制板230设置在主壳体110的外壁上，第四位置传感器240和第五位置传感器250沿第二方向间隔布置，此时通过第四位置传感器240和第五位置传感器250分别与第二挡光件220的配合即可限制副音箱200在第二方向上的极限位置。
进一步的，请结合参考图6-7，副音箱200还可以包括导向组件260，导向组件260设置在副腔体内，导向组件260至少为三组，且沿副腔体的长度方向均匀间隔布置。
具体而言，导向组件260包括固定安装在主壳体110侧壁的导向套261和固定安装在副壳体210上的导向柱262，该导向柱262能够插入到导向套261内，此时在副音箱200沿着第二方向移动时，由于导向柱262和导向套261的配合作用可很好的保证齿轮齿条组件420的啮合效果，从而使得副音箱200能够稳定的移动。
更具体地说，处于中间位置的导向柱262和导向套261的匹配间隙较小，而处于两端位置的导向柱262和导向套261的匹配间隙较大，通过三组导向组件260的设置一方面可保证齿轮齿条组件420的啮合效果，另一方面还可以控制副音箱200在移动过程中产生晃动。
除以上所述外，请参考图5，为了保证音箱结构2000移动的稳定性，在容置腔1100内还设置有一对导轨1200，同时为了便于限位件310一侧的固定安装，在容置腔1100内还设有固定安装位1300，限位件310的一侧可以穿过主壳体110而固定安装在该固定安装位1300处。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型。
