技术领域
本申请涉及电子技术领域，尤其涉及一种电子设备。
背景技术
目前，随着电子技术的不断发展，电视机、电脑等电子设备的显示屏幕除了具有传统的显示功能，还可以同时具有自发声功能，从而不需要电子设备内部再为扬声器设置安装位置，实现电子设备更加轻薄化的设计。为了实现显示屏幕自发声，电子设备会在显示屏幕的非显示侧设置电磁激励器，使得显示屏幕在电磁激励器的驱动下通过模态共振发出弯曲波进行发声。然而不难理解：强度越高的显示屏幕容易保持平整不容易变形，但为了实现显示屏幕能够实现振动发声以及达到良好的声学性能，则要求制作显示屏幕的材料质量轻、厚度薄，显示屏幕中承载光学膜片的发声基板的厚度以及弯曲强度不能过高，因此显示屏幕的振动发声性能和保持平整所需具有的强度是一对矛盾。
相关技术中，电子设备通常在显示屏幕的四周使用框架结构包裹住显示屏幕的边缘，实现对显示屏幕相对位置的固定。然而，随着诸如激光投影电视等具有超短焦投射的大尺寸显示屏幕的电子设备渐渐投入市场，对于超短焦激光投影屏幕的平整度要求较高，当屏幕尺寸较大时，现有的包裹式固定结构无法完全依靠显示屏幕自身的刚性来保持平整，尤其是由多层材料复合组成的尺寸 很薄的显示屏幕易受环境温湿度影响易产生凹凸或翘曲，进而导致激光投影屏幕所显示的图像几何失真。
因此，如何使得电子设备的自发声显示屏幕能够在获得良好声学发声性能的同时还能保持自身的平整，从而避免显示屏幕所显示的图像几何失真，是本领域亟需解决的技术问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

在正式介绍本申请之前，先结合附图，对比本申请所应用的场景以及相关技术中存在的问题进行介绍。
图1为一种电子设备的结构示意图，其中，以电子设备为电视机为例，该电子设备包括：屏幕框架11，显示屏幕12，以及至少两个扬声器(例如图1中的左扬声器131和右扬声器132)。更为具体地，图2为一种电子设备的剖面结构示意图，结合图1和图2所示，电视机的屏幕框架11在显示屏幕12四周对显示屏幕进行包裹固定，同时，显示屏幕12的显示侧用于显示画面内容，在显示屏幕12非显示侧的电子设备内部设置左扬声器131和右扬声器132设置，其中，左扬声器131和右扬声器132通常分别设置在用户观看显示屏幕12方向的左右两侧，提供左右声道声音。
随着市场上用户对于电子设备的需求逐渐向轻薄化的方向发展，以及电子技术的不断进步，越来越多的电子设备中显示屏幕、基础框架等关键组件能够以较薄的厚度实现，从而降低电子设备的整体厚度。因此，在如电子设备内部，除了设置一些用于显示的装置，给扬声器预留的空间越来越小，因此，一些技术中的电子设备具有了“自发声屏幕”，例如，可参考图3-图4，图3为一种另一种电子设备的结构示意图，图4为另一种电子设备的剖面结构示意图。
其中，以电子设备为激光投影电视作为示例性说明，主机10用于向显示屏 幕12投射激光光线，使得显示屏幕12显示图像画面内容，同时，主机10还可以向电磁激励器发送电信号，使得电磁激励器驱动显示屏幕振动发声。如图3和图4所示，电子设备除了用屏幕框架11对显示屏幕12的四周进行包裹固定，且在显示屏幕12的非显示侧设置至少一个电磁激励器(例如图中的电磁激励器141和电磁激励器142)。使得显示屏幕12除了能够用于显示画面内容，显示屏幕12还能够在电磁激励器141和142的作用下，通过模态共振发出的弯曲波进行发声，因此通过显示屏幕的自发声，使得电子设备中不需要再为扬声器设置安装位置，从而实现了电子设备更加轻薄化的设计。
然而，如图3和图4所示的电子设备通过屏幕框架11简单地对显示屏幕12四周进行包裹式的固定方式，虽然能够实现显示屏幕12与屏幕框架11之间相对位置的固定。但对于具有大尺寸的显示屏幕而言，其发声基板需要具有较高的刚性(发声基板较硬、较厚)以保持平整，但是刚性较高的发声基板又不利于振动发声。
另一方面，如果显示屏幕具有刚性较低的发声基板(较软、较薄)以更容易产生弯曲波振动，但是刚性较低的发声基板又容易由于其内部组成的多层材料的热膨胀系数不同，当显示屏幕所在环境温度条件变化后，会造成显示屏幕整体凹进或者凸起产生不平整的变形。此时仅仅依靠屏幕框架11对显示屏幕12的包裹固定无法完全避免大尺寸的显示屏幕12表面平整不产生凹凸变形，进而会导致显示屏幕所显示的图像几何失真。
因此，本申请提供一种电子设备，通过设显示屏幕的翻折设置，结合固定结构的连接共同为显示屏幕提供张力，以解决相关技术中的显示屏幕，尤其是超短焦投射自发声显示屏幕不能够保持足够平整而导致图像失真的技术问题。
下面结合附图以具体地实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图5为本申请提供的电子设备实施例一的结构示意图，如图5所示的电子设备可以是电视机、电脑等具有显示屏幕的电子设备。在一种可能的实现中，所述电视机可以是激光投影电视，则其显示屏幕可以是激光投影屏幕。
如图5示出了本申请提供的电子设备建立x、y、z的坐标轴后，从垂直于图中x方向截面的示意图，所述电子设备包括：主机20，显示屏幕21，屏幕框架22，至少一个电磁激励器23，以及至少一个固定结构24。
其中，主机20是电子设备中用于提供声音信号和图像信号的装置。主机20可以设置在显示屏幕21的非显示侧，记为第一侧；或者，主机20还可以设置在显示屏幕21的显示侧，即图中与第一侧相对的显示屏幕21的第二侧，本申请对主机20设置的具体位置以及设置方式不作限定。
主机20具体可以向显示屏幕21投射光线，使得显示屏幕21接收主机20投射的光线后，根据光线在第一侧显示图像画面的内容。在激光投影电视中，主机20可以是激光投影主机，则主机20向显示屏幕21投射的光线为激光。
主机20还具体可以向设置在显示屏幕21的第二侧的至少一个电磁激励器23发送电信号，如图5中示出一个电磁激励器作为示例性说明。显示屏幕第二侧所设置的至少一个电磁激励器23可用于在接收到主机发送的电信号后，单独或者共同根据电信号产生电磁力，以驱动显示屏幕21振动发声。
作为说明，本申请的如下实施例中，将不包含主机20的剩余结构统称为显示模组。换种说法，电子设备包括显示模组和主机两部分，针对显示模组的相 关实施例介绍请参考电子设备的相关实施例，如下不再重复说明。
而为了固定显示屏幕21，显示屏幕21的第二侧边缘处的一周屏幕框架22贴合，屏幕框架22的形状适应显示屏幕21的形状设置，用于对显示屏幕21进行支撑与保护。并且屏幕框架22只设置在显示屏幕21的第二侧，而在显示屏幕21的第一侧未设置屏幕框架22。例如，图5中的矩形显示屏幕21在第二侧一周的四个边的边缘处，与同样是矩形的屏幕框架22贴合设置。
特别地，在本申请提供的电子设备中，显示屏幕21在与屏幕框架22贴合设置后，还继续延伸出屏幕框架22的范围，并绕设到显示屏幕21的第二侧。例如，在图5中，显示屏幕21的边缘处与屏幕框架22贴合，并以屏幕框架22的最上方为轴，由第一侧向第二侧方向进行翻转。
在一些实施例中，显示屏幕21的至少两个相对的边均绕设到显示屏幕21第二侧，从而通过相对的两个边的拉力带来对显示屏幕21所提供的张力，使得显示屏幕21在两个相对的边之间保持平整。例如，在图5中所建立的坐标系中，矩形显示屏幕21在x轴正方向和x轴负方向的两个边相对，显示屏幕21可以在这两个相对的边缘处绕设到第二侧，以提供相对的拉力。同时，矩形显示屏幕21在y轴正方向和y轴负方向的两个边相对，显示屏幕21也可以在这两个相对的边缘处绕设到第二侧，以提供相对的拉力。或者，如图5所示的电子设备的显示屏幕在上述四个两两相对的边缘处均绕设到第二侧。
在一些实施例中，向第二侧翻转的可以是显示屏幕21的一部分，即，生产商可以在制作时显示屏幕21的尺寸设置为大于屏幕框架22的尺寸，从而在显示屏幕21与屏幕框架22贴合设置之后，显示屏幕21的四个边的边缘处还能够伸出屏幕框架22，并以屏幕框架22为轴绕设到显示屏幕21的第二侧之后。
在一些实施例中，当本申请提供的电子设备的显示屏幕绕21设到第二侧之后，由同样设置在显示屏幕21第二侧的至少一个固定结构对显示屏幕提供张力。如图5所示，以固定结构24为拉簧为例进行说明。其中，固定结构24的第一端242与屏幕框架连接，第二端241与绕设到第二侧的显示屏幕21连接。可以理解的是，在如图5所示的示例中，当矩形的显示屏幕21在四个边缘处均绕设到第二侧后，在边缘的第二侧均设置有至少一个固定结构24，从而通过两两相对的边缘为显示屏幕21提供向x轴正方向、x轴负方向、y轴正方向和y轴负方向四个边方向的张力。
综上，在本申请实施例提供的电子设备中，通过显示屏幕与屏幕框架贴合设置之后，显示屏幕还进一步在至少两个相对的边缘处伸出屏幕框架，并以屏幕框架为轴绕设到显示屏幕的第二侧，随后通过与屏幕框架连接的固定结构对显示屏幕进行固定。使得显示屏幕在至少两个相对的边缘处，通过绕设到第二侧部分所连接的固定结构提供相对方向的拉力，从而为显示屏幕的表面提供张力，进而使得显示屏幕能够通过固定结构对显示屏幕的拉力来保持显示屏幕的平整。
尤其是对于超短焦投射自发声屏幕，可以对显示屏幕整体提供张力，使得显示屏幕不会由于其多层材料的热膨胀系数不同而在环境温度变化后显示屏幕整体凹进或者凸起产生不平整的变形，进而保证了显示屏幕在超短焦投射下所显示的图像不会几何失真。
在一些实施例中，本申请提供的电子设备中，显示屏幕绕设到第二侧与固定结构连接的可以是显示屏幕本身，或者，还可以是显示屏幕的一部分。例如，图6为激光投影屏幕的结构示意图，当显示屏幕为自发声激光投影屏幕时，如 图6所示，所述自发声激光投影显示屏幕包括：发声基板212和显示结构211，其中，发声基板212的一侧与显示结构211贴合设置，至少一个电磁激励器设置在发声基板212的另一侧。更为具体地，图7为激光投影屏幕中发声基板的结构示意图，结合图6和图7，发声基板具体包括：第一蒙皮2121、中间层2122和第二蒙皮2123。第一蒙皮2121和第二蒙皮2122分别贴合设置在中间层2123的两侧，第一蒙皮2121、中间层2122和第二蒙皮2123的表面积相同，所述中间层可以由多个呈六角形排列的蜂窝芯连接而成。
则当如图6和图7所示的显示屏幕在翻转时，可以只将显示屏幕中发声基板上的一张或两张蒙皮向后翻转，并与固定结构连接，由固定结构对蒙皮的拉力实现对显示屏幕整体的张力。例如，在图5所示的示例中，若显示屏幕21是如图6和图7所示的激光投影屏幕，则显示屏幕21第二侧边缘一周的第二蒙皮2123，与屏幕框架22贴合设置。随后，显示屏幕21的第二蒙皮2123进一步延伸出屏幕框架22之外，并以屏幕框架22为轴翻转，绕设到显示屏幕21的第二侧后，第二蒙皮2123与固定结构24的第一端241连接。此时，由于第二蒙皮2123、中间层2122、第一蒙皮2121和显示结构211依次贴合设置，则固定结构通过对第二蒙皮2123的拉力可以实现对显示屏幕整体的拉力，并最终由相对的两个边缘的拉力实现对显示屏幕整体的张力。此外，除了上述示例中第二蒙皮绕设到显示屏幕的第二侧，还可以是第一蒙皮绕设到显示屏幕的第二侧，或者还可以是第一蒙皮和第二蒙皮共同绕设到显示屏幕的第二侧，其实现方式与原理相同，不再赘述。
在一些实施例中，第一蒙皮2121和第二蒙皮2122的制作材料为高分子材料，所述高分子材料包括但不限于：聚氨酯或者聚苯乙烯。其中，由于本实施 例中显示屏幕组成部分中的蒙皮由高分子材料组成，其具有较高的韧性，因此可以直接与固定结构连接，使得固定结构可以直接通过蒙皮提供对显示屏幕的拉力，而同时保证显示屏幕不受损伤。与相关技术中由其他材料制成的显示屏幕不能被固定结构直接作用，故还需要加入对显示屏幕的保护装置来提供拉力相比，极大地减少了显示屏幕的结构复杂度，降低了显示屏幕的制作成本，显示屏幕所减少的保护装置还可以用于设置电子设备其他的装置，还提高了电子设备内部的空间利用率。
图8为本申请提供的显示屏幕的蒙皮的结构示意图，如图8所示，第二蒙皮2123的尺寸略大于显示结构211的尺寸，并且在四个边缘的延伸处均设置有至少一个开孔213，并且在开孔之上设置空心铆钉214。所述空心铆钉214用于，使固定结构通过空心铆钉能够为第二蒙皮提供较为均匀的拉力，进一步对显示屏幕的结构进行保护。因此，当如图8所示的第二蒙皮2123的延伸处绕设到第二侧之后，第二蒙皮2123上设置的空心铆钉214与固定结构24的连接方式如图9所示，图9为本申请提供的固定结构的连接方式示意图，其中，在绕设到第二侧的第二蒙皮2123上设置了空心铆钉214一一对应的位置处，均设置一个固定结构24。所有固定结构24的第一端连接对应的空心铆钉214，第二端连接屏幕框架22，一个边缘处所有的固定结构共同为该边缘处翻转到第二侧的蒙皮提供拉力。
在一些实施例中，图10为本申请提供的显示屏幕的包裹结构示意图，其中，当电子设备完成对蒙皮如图9所示的固定方式后，可以在电子设备显示屏幕各个边缘处，套设如图10所示的外框25，以对显示屏幕以及固定结构进行保护。在一些实施例中，在上述矩形的显示屏幕四个边缘处中，由于显示屏幕上侧边 缘所连接的拉簧除了提供显示屏幕的拉力，还需要承担显示屏幕本身的重量，因此，显示屏幕上侧边缘所连接的拉簧的弹性系数，大于显示屏幕下侧边缘所连接的拉簧的弹性系数，以抵消上侧拉簧所承担的显示屏幕的重量。
综上，在本申请如图5-10所示的实施例中，示出了将显示屏幕翻转到屏幕框架的第二侧，并与固定结构直接连接的显示屏幕固定结构，而在其他可能的实现方式中，由于单纯地将显示屏幕增大仅为了绕设到第二侧进行固定虽然具有结构简单、易于实现的技术效果，但是在具体实现中出于生产成本方面考虑，可以将显示屏幕的大小还是限定在与屏幕框架相同，而将显示屏幕边通过连接布进行扩展，通过显示屏幕所连接的连接布对显示屏幕进行“延伸”，从而将显示屏幕所连接的连接布绕设到显示屏幕第二侧并并与固定结构连接，使得固定结构通过连接布向显示屏幕提供张力。
其中，图11为本申请提供的电子设备实施例二的结构示意图，如图11所示的电子设备包括：主机20，显示屏幕21，屏幕框架22，至少两个连接布26，与连接布26一一对应的支撑杆27，至少一个电磁激励器23，以及与支撑杆27对应的至少一个固定结构24。
其中，对于主机20、显示屏幕21、屏幕框架22以及至少一个电磁激励器23的描述可以参照如图5所示的实施例，本实施例不再赘述。
而在本实施例中，显示屏幕的至少两个相对的边缘处均与所述至少两个连接布26连接，并贯穿一个支撑杆27，从而实现对显示屏幕本身进行的延伸，此时，显示屏幕可以相当于既包括显示屏幕本身，又包括了所有连接布26。
例如，在如图11所建立的坐标系中，矩形显示屏幕21在x轴正方向和x轴负方向的两个边相对，显示屏幕21在这两个相对的边缘处分别与一个连接布 26连接，并且相对的边缘处所连接的两块连接布26还分别贯穿一个连接杆27后绕设到显示屏幕21的第二侧。同时，矩形显示屏幕21在y轴正方向和y轴负方向的两个边相对，显示屏幕21在这两个相对的边缘处分别与一个连接布26连接，并且相对的边缘处所连接的两块连接布26还分别贯穿一个连接杆27后绕设到显示屏幕21的第二侧。或者，如图11所示的电子设备的显示屏幕在上述四个两两相对的边缘处均与连接布26连接，并贯穿连接杆27后绕设到第二侧。
在一些实施例中，图12为本申请系统的显示屏幕的蒙皮的结构示意图，如图12所示，显示屏幕21的第二蒙皮2123在四个边缘处均各自连接一个连接布26，连接布绕设一个支撑杆27。因此，当如图12所示的连接布26贯穿支撑杆27绕设到第二侧之后，支撑杆27与同样设置在显示屏幕21第二侧的至少一个固定结构24连接，由至少一个固定结构24通过支撑杆27和连接布26向显示屏幕21提供张力。
至少一个固定结构24与支撑杆27的连接方式如图13所示，图13为本申请提供的固定结构的连接方式示意图，其中，在绕设到第二侧的连接布26固定结构一一对应的位置设置开孔215，用于容纳固定结构24的第二端。则在如图13的示例中，以固定结构24为拉簧为例进行说明。其中，固定结构24的第一端242与屏幕框架连接，所有固定结构24的第二端241通过对应的开孔连接支撑杆27。则支撑杆27上连接的至少一个固定结构24共同通过该支撑杆27向贯穿的连接布26提供拉力，支撑杆27可以使得至少一个固定结构24提供的拉力均匀地分布在整个连接布之上，防止连接布被固定结构24直接拉扯而损坏。此时，由于连接布26与第二蒙皮2123连接，而第二蒙皮2123、中间层2122、 第一蒙皮2121和显示结构211依次贴合设置，则固定结构通过支撑杆27对连接布26的拉力可以实现对显示屏幕整体的拉力，并最终由相对的两个边缘的拉力实现对显示屏幕整体的张力。
可以理解的是，在如图11所示的示例中，当矩形的显示屏幕21在四个边缘处均与贯穿支撑杆的连接布连接，并且连接布绕设到第二侧后，在四个边缘的第二侧均设置有至少一个固定结构24，边缘设置的至少个一个固定结构24均通过支撑杆向连接布提供拉力，进而通过两两相对的边缘处的连接布，为显示屏幕21提供向x轴正方向、x轴负方向、y轴正方向和y轴负方向四个边方向的张力。
在一些实施例中，图14为本申请提供的显示屏幕的包裹结构示意图，其中，当电子设备完成对蒙皮如图13所示的固定方式后，可以在电子设备显示屏幕各个边缘处，套设如图14所示的外框25，以对显示屏幕以及固定结构进行保护。
在一些实施例中，在上述矩形的显示屏幕四个边缘处中，由于显示屏幕上侧边缘所连接的拉簧除了提供显示屏幕的拉力，还需要承担显示屏幕本身的重量，因此，显示屏幕上侧边缘所连接的拉簧的弹性系数，大于显示屏幕下侧边缘所连接的拉簧的弹性系数，以抵消上侧拉簧所承担的显示屏幕的重量。
综上，在本申请实施例提供的电子设备中，通过显示屏幕与屏幕框架贴合设置之后，显示屏幕还在至少两个相对的边缘处连接被支撑杆贯穿的连接布，并且当连接布以屏幕框架为轴绕设到显示屏幕的第二侧后，通过与屏幕框架连接的固定结构对支撑杆的进行固定。使得显示屏幕在至少两个相对的边缘处，通过绕设到第二侧部分所连接的连接布提供相对方向的拉力，从而为显示屏幕第一侧的表面提供张力，进而使得显示屏幕能够通过固定结构对显示屏幕的拉 力保持显示屏幕的平整。
尤其是对于超短焦投射自发声屏幕，可以对显示屏幕整体提供张力，使得显示屏幕不会由于其多层材料的热膨胀系数不同而在环境温度变化后显示屏幕整体凹进或者凸起产生不平整的变形，进而保证了显示屏幕所显示的图像不会几何失真。
本申请实施例还提供一种激光电视，包括：盒子，被配置为发射投影光线；显示屏幕，被配置为接收所述投影光线，并在所述显示屏幕上呈现图像画面；至少一个电磁激励器，被配置为驱动所述显示屏幕振动发声。其中，盒子即为前文中介绍的主机的一种，具体介绍参考前文。

在一些实施例中，所述固定结构具体用于通过为所述显示屏幕提供张力，使所述显示屏幕保持平整。
在一些实施例中，所述显示屏幕包括：发声基板和显示结构，所述发声基板和所述显示结构贴合设置，所述至少一个电磁激励器设置在所述发声基板一侧；所述发声基板的包括：第一蒙皮、第二蒙皮和中间层；所述第一蒙皮和所述第二蒙皮分别贴合设置在所述中间层两侧。
