Description

电子设备
本申请要求于2023年07月05日提交国家知识产权局、申请号为202310822244.7、发明名称为“电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子产品技术领域，尤其涉及一种电子设备。
背景技术
随着社会的发展，手机的普及率越来越高，换机周期也越来越长，因此对手机的防护要求和精致度需求也越来越高。为实现超高屏占比，听筒处采用窄缝出音的方案，但是，外界的水渍(例如用户的汗液)、油污和杂质等容易从窄缝出音位置进入整机内部，当外界的水渍、油污和杂质等接触到显示面板时，可能会导致显示面无法正常显示，影响用户的使用体验。
发明内容
本申请实施例提供一种电子设备，用于防护显示屏中的显示面板免受外界水渍、油污等干扰源的干扰，提高显示屏的使用寿命。
为达到上述目的，本申请的实施例采用如下技术方案：
本申请提供了一种电子设备，该电子设备包括：显示屏和中框，显示屏包括盖板和显示面板，盖板位于显示面板的显示侧，盖板的周向侧面凸出于显示面板的周向侧面；显示屏安装在中框上中框包括边框，边框的内周面上设置有第一凸台和第二凸台，第一凸台与第二凸台均沿边框的内周面的周向延伸，第一凸台和第二凸台间隔开，显示屏、边框、第一凸台、和第二凸台之间共同形成出音通道；第一凸台包括背离边框的第一侧壁面，第二凸台包括背离边框的第二侧壁面；显示面板包括第一侧面，第一侧面为显示面板朝向出音通道的一面，第一侧面包括第一区域，第一区域为第一侧面对应出音通道的区域；第一区域上设置有第一胶体，显示屏与第一侧壁面之间设置有第二胶体，显示屏与第二侧壁面之间设置有第三胶体，显示屏与边框的内周面之间设置有第四胶体，第一胶体的一端与第二胶体相连，第一胶体的另一端与第三胶体相连，第二胶体与第四胶体相连，第三胶体与第四胶体相连。
这样一来，第一胶体、第二胶体、第三胶体和第四胶体共同形成了防护，用于保护显示面板的周向侧面免受出音通道中水渍、油污等干扰源的侵蚀。具体地，水渍、油污等干扰源通过出音通道进入到电子设备后，一部分干扰源会朝向第一区域扩散，通过在第一区域上设置第一胶体，可以避免第一区域免受干扰源的侵蚀。另一部分干扰源会朝向出音通道的两侧进行扩散，朝向出音通道两侧扩散的另一部分干扰源会被第二胶体、第三胶体和第四胶体阻拦。综上，由出音通道进入到电子设备内部的干扰源，会被第一胶体、第二胶体、第三胶体和第四胶体阻拦，不会扩散至显示面板的周向侧面，进而在保证出音通道很好的出音的前提下，避免显示面板的周向侧面受到出音通道中水渍、油污等干扰源的侵蚀。
另外，通过设置第四胶体可以将盖板与边框之间密封，避免环境中的水渍、油污等干扰源通过盖板与边框之间的避让缺口进入到电子设备的内部，将第二胶体和第三胶体分别与第四胶体相连，可以更好的保证盖板与边框之间的密封性。进而全面的保证电子设备的正常使用，改善用户的使用体验。

本申请提供一种电子设备，请参阅图1，图1为本申请一些实施例提供的电子设备的结构示意图。该电子设备100为听筒110采用窄缝出音的一类电子设备100。该电子设备100可以为用户设备(user equipment，UE)或者终端设备(terminal)等。例如，电子设备100可以为大屏显示终端、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备、车载设备、可穿戴设备、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的显示终端、无人驾驶(self driving)中的显示终端、远程医疗(remote medical)中的显示终端、智能电网(smart grid)中的显示终端、运输安全(transportation safety)中的显示终端、智慧城市(smart city)中的显示终端、智慧家庭(smart home)中的显示终端。其中，大屏显示终端包括但不限于智慧屏、平板电脑(portable android device，PAD)、笔记本电脑、台式电脑、电视机、投影仪等设备。
请继续参阅图1，本实施例以及下文各实施例是以电子设备100为手机进行示例性说明。电子设备100近似呈矩形板状。在此基础上，为了方便后文各实施例的描述，建立XYZ坐标系，定义电子设备100的宽度方向为X轴方向，电子设备100的长度方向为Y轴方向，电子设备100的厚度方向为Z轴方向。可以理解的是，电子设备100的坐标系设置可以根据实际需要进行灵活设置，在此不做具体限定。在其他一些实施例中，电子设备100的形状也可以为方形平板状、圆形平板状、椭圆形平板状等等，在此不做具体限定。
在本申请的一些实施例中，请继续参阅图1，电子设备100包括显示屏120。
可以理解的是，图1仅示意性的示出了电子设备包括的一些部件，这些部件的实际形状、实际大小、实际位置和实际构造不受图1的限制。
显示屏120用于显示图像、视频等，显示屏120可以为3D显示屏或者2.5D显示屏等(图1中所示显示屏120为3D显示屏)。请参阅图2和图3，图2为图1中所示的电子设备在A-A处的剖视图；图3为图2中所示的B处的放大图。显示屏120可以 包括盖板121和显示面板122。盖板121与显示面板122层叠设置，盖板121位于显示面板122的显示侧(例如图3中所示的盖板121位于显示面板122在Z轴正方向的一侧)，即用户在使用电子设备时，盖板121面向用户。
其中，盖板121的面积大于显示面板122的面积，盖板121的周向侧面凸出于显示面板122的周向侧面。盖板121将显示面板122完全覆盖，盖板121主要用于对显示面板122起保护以及防尘作用。盖板121的材质包括但不限于玻璃。盖板121还具有防冲击、耐刮花、耐油污、防指纹、增强透光率等功能。
显示面板122可以采用柔性显示面板，也可以采用刚性显示面板。例如，显示面板122可以为有机发光二极管(organic light‐emitting diode，OLED)显示面板，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active‐matrix organiclight‐emitting diode，AMOLED)显示面板，迷你发光二极管(mini organic lightemittingdiode)显示面板，微型发光二极管(micro organic light‐emitting diode)显示面板，微型有机发光二极管(micro organic light‐emitting diode)显示面板，量子点发光二极管(quantum dot light emitting diode，QLED)显示面板，液晶显示面板(liquid crystal display，LCD)等。
请继续参阅图3，电子设备100还可以包括背壳130和中框140，背壳130与中框140共同形成电子设备100的壳体，用于保护电子设备100的内部电子元器件。背壳130位于显示面板122远离盖板121的一侧(例如图3中所示显示面板122的Z负方向所在的一侧)，并与盖板121、显示面板122层叠且间隔设置。中框140位于背壳130与盖板121之间。背壳130固定于中框140上，示例性的，背壳130可以通过粘胶固定连接于中框140上，中框140也可以与背壳130为一体成型结构，即中框140与背壳130为一个结构件整体。盖板121、背壳130与中框140围成电子设备100的容纳腔。该容纳腔将显示面板122、电路板、摄像头、闪光灯和听筒110容纳在内。
在本申请的一些实施例中，以电子设备100为手机为例，请参阅图3至图5，图4为图1中所示的电子设备的局部示意图；图5为本申请另一些实施例提供的电子设备的中框的示意图。为了实现手机的超高屏占比，手机的听筒处采用窄缝出音的方案。该听筒是指用户通话时的听筒，一般位于显示屏120的顶部(例如听筒设置在图4中所示的显示屏120位于Y轴正方向的一侧)。具体地，中框140包括边框141，边框141的内周面上设置有第一凸台1421和第二凸台1422，第一凸台1421与第二凸台1422均沿边框141的内周面的周向延伸，第一凸台1421和第二凸台1422间隔开，显示屏120、边框141、第一凸台1421与第二凸台1422之间共同形成出音通道150；盖板121包括靠近听筒的第二侧面1211，第二侧面1211设有避让缺口1212，具体地，避让缺口1212位于第二侧面1211的中间位置，且朝向Y轴负方向凹陷形成，避让缺口1212与出音通道150连通。
在另一些实施例中，避让缺口也可以形成于边框上，具体可以是在与第二侧面1211同侧的边框的侧面开设一避让缺口1212，该避让缺口1212可以为一通槽，将出音通道150与外界连通。
手机通话时的声音由容纳腔中的听筒发出，经由出音通道150传播至手机外，然后传输到用户的耳朵。由此，通过设置出音通道150，不需要在显示屏120上单独设 置用于出音的出音孔，进而达到提高显示屏120的屏幕占比的目的。
然而，为了保证用户可以清晰的听到听筒发出的声音，请参考图3，出音通道150一般不设置物理防护。请参照图3中箭头所示的路径，用户在使用手机的过程中，用户手上或者耳朵上的汗液容易从出音通道150的位置进入到手机内部，使得汗液接触到显示面板122，影响显示面板122的正常运行，影响用户的使用体验。另一种方案是在出音通道150处设置纳米镀膜的方案，然而，纳米镀膜在电子设备长时间的使用后，会被环境中的水分等水渍侵蚀，防护效果不佳。
可以理解的是，在电子设备的使用过程中，用户的汗液和外界环境中的水分等水渍，容易通过出音通道150进入电子设备的内部，通过出音通道150传递到显示面板122上，导致显示面板122无法正常使用。其中，显示面板122包括多个子功能层，多个子功能层层叠设置，因此，显示面板122的周向侧面由多个子功能层的周向侧面组成，扩散至显示面板122周向侧面的汗液或者水渍，容易通过相邻子功能层之间的缝隙进入到显示面板122的内部，因此，显示面板122的周向侧面极易受到水渍与汗液的侵蚀。
具体地，显示面板122中的功能层可以包括偏光片(Polarizer，POL)，POL层上设有聚乙烯醇(PolyvinylAlcohol，PVA)薄膜，当汗液接触到PVA层后，会导致POL层边缘部分偏光过程缺少红色，引发发黄现象，影响用户的使用体验。
为了解决上述技术问题，请参阅图5至图7，图6为本申请另一些实施例提供的电子设备的显示屏的示意图；图7为本申请另一些实施例提供的电子设备的剖视图。
本申请提供了一种胶体电子设备，电子设备的边框141的内周面上设置有凸台142，凸台142可以包括第一凸台1421和第二凸台1422，第一凸台1421位于出音通道150的一端(例如图5中所示的出音通道150在X轴负方向的一端)，第二凸台1422位于出音通道150的另一端(例如图5中所示的出音通道150在X轴正方向的一端)，第一凸台1421包括背离边框141的第一侧壁面1421a，第二凸台1422包括背离边框141的第二侧壁面1422a。
显示面板122包括第一侧面1221，第一侧面1221与第二侧面1211朝向相同(例如图7中所示第二侧面和第一侧面均位于显示屏在Y轴正方向的一侧)，第一侧面1221包括第一区域1222，第一区域1222为第一侧面1211对应出音通道150的区域(例如图6中所示的第一区域1222)；一般情况下，出音通道150位于第二侧面1211的中间位置，出音通道150的长度一般为第二侧面1211长度的1/5-1/3，具体地，出音通道150的长度可以为第二侧面1211长度的1/3、1/4或者1/5。第一区域1222位于第二侧面1211的中间位置，第一区域1222的长度大于出音通道150的长度，出音通道150包括在其长度方向(例如图5中所示的X轴方向)的第一边缘和第二边缘，第一边缘在第一区域1222所在平面的正投影位于第一区域1222内，第二边缘在第一区域1222所在平面的正投影位于第一区域1222内，也即第一区域1222的两端均超出出音通道150的两端(第一边缘和第二边缘)。
请参阅图6至图8，图8为本申请一些实施例提供的电子设备的示意图。第一区域1222上设置有第一胶体161，显示屏120与第一侧壁面1421a之间设置有第二胶体1621，显示屏120与第二侧壁面1422a之间设置有第三胶体1622，显示屏120与边框 141的内周面之间设置有第四胶体163。
其中，第一胶体161的一端与第二胶体1621密封连接，由此，使得扩散至第一胶体161与第二胶体1621连接处的水渍，无法通过第一胶体161与第二胶体1621的连接处进入到电子设备内部；第二胶体1621与第四胶体163密封连接，由此，使得扩散至第二胶体1621与第四胶体163连接处的水渍，无法通过第二胶体1621与第四胶体163的连接处进入到电子设备内部。第一胶体161的另一端与第三胶体1622密封连接，使得扩散至第一胶体161与第三胶体1622连接处的水，无法通过第一胶体161与第三胶体1622连接处进入到电子设备内部；第三胶体1622与第四胶体163密封连接，使得扩散至第三胶体1622与第四胶体163连接处的水，无法进入到电子设备的内部。
这样一来，第一胶体161、第二胶体1621、第三胶体1622和第四胶体163共同形成了胶体防护，用于保护显示面板122的周向侧面免受出音通道150中水渍的侵蚀。具体地，请参阅图8中箭头所示的路径，水渍通过出音通道150进入到电子设备100后，一部分水渍会朝向第一区域1222扩散，通过在第一区域1222上设置第一胶体161，使得第一区域1222免受水渍的侵蚀。另一部分汗液会朝向出音通道150的两侧(例如图8中所示的出音通道150在X轴方向的两侧)进行扩散，朝向出音通道150两侧扩散的另一部分汗液会被第二胶体1621、第三胶体1622和第四胶体163阻拦。
综上，由出音通道150进入到电子设备100内部的汗液，会被第一胶体161、第二胶体1621、第三胶体1622和第四胶体163阻拦，不会扩散至显示面板122的周向侧面，进而在保证电子设备出音状况良好的前提下，避免显示面板122的周向侧面受到出音通道150中水渍的侵蚀。
另外，通过设置第四胶体163可以将盖板121与边框141之间密封，避免环境中的水分通过盖板121与边框141之间的缝隙进入到电子设备100的内部，将第二胶体1621与第四胶体163相连，第三胶体1622与第四胶体163相连，可以更好的保证盖板121与边框141之间的密封性。进而全面的保证电子设备100的正常使用，改善用户的使用体验。
在本申请的一些实施例中，第一凸台1421背离所述出音通道150的一端，与第二凸台1422背离所述出音通道150的一端相连接。
在本申请的一些实施例中，请参阅图9，并结合图7，图9为图6中所示的显示屏的仰视图。显示屏120还可以包括功能层123，具体地，功能层123可以为铜箔层，铜箔层在显示屏120中起到屏蔽电磁干扰的作用，铜箔层与显示面板122层叠设置，铜箔层位于显示面板122背离盖板121的一侧，显示面板122的周向侧面凸出于铜箔层的周向侧面；铜箔层与显示面板122之间通过网格胶粘接，铜箔层朝向显示面板122的一侧还可以设有泡棉层，用于避免铜箔层与显示面板122之间的硬性碰撞。
显示面板122还可以包括第二区域1223，第二区域1223位于显示面板122背离盖板121的一侧表面，第二区域1223露出于功能层，第二区域1223与第一区域1222相连；第一胶体161覆盖第一区域1222和第二区域1223。这样一来，第一胶体161可以覆盖显示面板122暴露于出音通道150的区域，进而全面的保护显示面板122。
可以理解的是，请参考图10，图10为本申请另一些实施例提供的电子设备出音通道处的示意图。参照图10中箭头所示的路径，显示面板122的第二区域1223暴露 于出音通道150的空间中，由外界进入到出音通道150的汗渍和水汽，会接触至第二区域1223，由于显示面板122上设有多个电子元器件，汗液扩散至第二区域1223后，显示面板122也有发生损坏的可能性。因此，在第二区域1223涂覆第一胶体161，可以将显示面板122上与第一区域1222相连的第二区域1223进行遮盖，阻挡出音通道150中的水汽和汗液侵蚀第二区域1223，进而对显示面板122提供更加全面的保护，使得显示面板122免受出音通道150中汗渍和水汽的侵蚀。
其中，第一胶体161可以包括第一部分1611，第一部分1611设置于第一区域1222，第一部分1611厚度的最大值，小于或等于第二侧面1211到第一侧面1221的距离。其中需要说明的是，第一胶体161通过点胶机进行点胶，在整个点胶的过程中，点胶机不可能保证点胶厚度完全一样，当第一部分1611厚度的最大值，小于或等于第二侧面1211到第一侧面1221的距离时，也就是说明，第一部分1611的厚度，均小于或等于第二侧面1211到第一侧面1221的距离时。即第一部分1611不会凸出于第二侧面1211，用户从避让缺口观察电子设备100内部时，不会观察到第一胶体161，进而提高电子设备的产品质量，保证电子设备100整体的美观，改善用户的使用体验。
第一胶体161还可以包括第二部分1612，第二部分1612设置于第二区域1223，第二部分1612厚度的最大值，小于或等于功能层123的厚度。也就是说明，第二部分1612的厚度，均小于或等于功能层123的厚度。即第二部分1612不凸出于功能层123的底面。需要说明的是，第二胶体1621和第三胶体1622抵接在功能层123的底面，第二胶体1621和第三胶体1622对功能层123具有一定的应力，当第二部分1612凸出于功能层123的底面时，第一胶体161的第二部分1612会占用第二胶体1621和第三胶体1622的空间，导致第二胶体1621和第三胶体1622对功能层123的应力增大，使得功能层123存在变形的风险。因此，通过限制第二部分1612厚度的最大值，小于或等于功能层123的厚度，可以避免因上述原因导致功能层123变形的现象出现。
其中，第一胶体161的材质为热熔胶。当电子设备100长时间的使用后，第一胶体161发生损坏，可以将显示屏120从中框140上拆卸下来，然后对第一胶体161进行加热，由于第一胶体161是热熔胶，对其加热后，将其取下，重新涂覆新的热熔胶即可。
在本申请的一些实施例中，第一胶体161的第一部分1611和第二部分1612相连。
在本申请的一些实施例中，请继续参阅图8，第二胶体1621位于出音通道150的一侧(例如图8中所示出音通道150在X轴负方向的一侧)，第三胶体1622位于出音通道150的另一侧(例如图8中所示的出音通道150在X轴正方向的一侧)。
这样，一方面，使得第二胶体1621可以规避出音通道150，避免第二胶体1621和第三胶体1622封堵出音通道150的现象出现，保证出音通道150的正常出音。另一方面，可以减少第二胶体1621和第三胶体1622的使用量，进而减少电子设备100的生产成本，减轻电子设备100的整体重量，提高用户的使用手感。
其中，第二胶体1621与第一胶体161的一端(例如图8中所示的第一胶体161在X轴负方向的一端)相连，由此，扩散至第二胶体1621与第一胶体161连接处的水，无法通过第二胶体1621和第一胶体161的连接处进入到电子设备内部；第二胶体1621与第四胶体163相连，由此，第二胶体1621与第四胶体163连接处的水，无法 通过第二胶体1621与第四胶体163的连接处进入到电子设备的内部。
第三胶体1622与第一胶体161的另一端(例如图8中所示的第一胶体161在X轴正方向的一端)相连，由此，扩散至第三胶体1622与第一胶体161连接处的水渍，无法通过第三胶体1622与第一胶体161的连接处进入到电子设备的内部；第三胶体与第四胶体相连，由此，扩散至第三胶体1622与第四胶体163连接处的水，无法通过第三胶体1622与第四胶体163的连接处进入到电子设备的内部。
请继续参考图8和图10，边框141可以包括第一边框1411、第二边框1412和第三边框1413，第一边框1411与第二侧面1211相对设置，第一边框1411的一端(例如图8中所示的第一边框1411在X轴负方向的一端)与第二边框1412相连，第一边框1411的另一端(例如图8中所示的第一边框1411在X轴正方向的一端)与第三边框1413相连；第二胶体1621形成“L”型胶体；第三胶体1622形成“L”型胶体。
具体地，第一凸台包括相连的第一子凸台和第二子凸台，第一子凸台的延伸方向与第一边框1411的延伸方向平行，第二子凸台的延伸方向与第二边框1412的延伸方向平行，第一子凸台包括背离边框141的第一子侧壁面，第二子凸台包括背离边框141的第二子侧壁面，第一子侧壁面与第二子侧壁面组成第一侧壁面1421a，第一胶段1621a位于所述第一子侧壁面与显示屏120之间，第二胶段1621b位于第二子侧壁面与显示屏120之间,第一胶段1621a和第二胶段1621b在第一边框1411和第二边框1412的过渡位置连接。
第二凸台包括相连的第三子凸台和第四子凸台，第三子凸台的延伸方向与第一边框1411的延伸方向平行，第四子凸台的延伸方向与第三边框1413的延伸方向平行，第三子凸台包括背离边框141的第三子侧壁面，第四子凸台包括背离边框141的第四子侧壁面，第三子侧壁面和第四子侧壁面组成第二侧壁面1422a，第三胶体1622包括相连的第三胶段1622a和第四胶段1622b，第三胶段1622a位于第三子侧壁面与显示屏120之间，第四胶段1622b位于第四子侧壁面与显示屏120之间。第三胶段1622a和第四胶段1622b在第一边框1411和第三边框1413的过渡位置连接。
需要说明的是，相对于第一边框1411、第二边框1412和第三边框1413上的平直的第四胶体163而言，第一边框1411与第二边框1412的连接位置、第一边框1411与第三边框1413的连接位置为过渡位置，过渡位置点胶难度大。将第二胶体1621设置为“L”型胶体，可以很好的将第一边框1411和第二边框1412的过渡位置包裹住；将第三胶体1622设置为“L”型胶体，可以很好的将第一边框1411和第三边框1413的过渡位置包裹住。
具体地，参考图8，其中，边框141在过渡位置为圆角，盖板在过渡位置也设置为圆角，两个圆角相互配合，圆角的大小可以根据电子设备的大小和具体的设计要求进行确定。盖板与边框在过渡位置的连接很难保证配合的精确度，从而导致过渡位置第四胶体163的点胶难度较大，无法保证过渡位置的密封性。
然而，点胶机单位时间内的点胶量一般是固定的。并且第四胶体163设置在过渡位置时，点胶机需要不断变换方向，因此，过渡位置的第四胶体163很难保证该位置的密封性，通过设置“L”型的第二胶体1621和第三胶体1622，可以弥补过渡位置边框141与盖板之间的加工误差，为第四胶体163的点胶提供大小稳定的点胶空间，进而 保证第四胶体163点胶后，盖板与边框141之间配合的稳定性。
同时，参考图8中的箭头路径，在第一边框1411和第二边框1412之间的过渡位置、第一边框1411和第三边框1413之间的过渡位置，外界环境中的水汽等水渍进入电子设备内部的可能性较大。由此，在第一边框1411和第二边框1412之间的过渡位置设置第二胶体1621、第一边框1411和第三边框1413之间的过渡位置上设置第三胶体1622，之后再设置第四胶体163可以更好的保证过渡位置的密封性，进而避免外界环境中的汗液与水分等水渍进入电子设备内部，更好的保护电子设备内部的电器元件，提高产品质量。
具体地，在一些实施例中，第二胶体1621和第三胶体1622的材质可以为硅胶，硅胶体质的胶体具有良好的电绝缘性能、不易老化、吸附性能高、热稳定性好、化学性质稳定等优点。
在本申请的一些实施例中，请继续参阅图8至图10，中框140还可以包括中板145，边框141连接在中板145的周向边缘；电子设备还可以包括第五胶体164，第五胶体164设置于显示屏120与中板145之间，用于将显示屏120粘接在中板145上。
其中，第五胶体164包括朝向出音通道的第一端，第二胶体1621与第五胶体164的第一端密封连接，第三胶体1622与第五胶体164的第一端密封连接。
具体地，一方面，中板145包括朝向显示屏120的支撑面1451，第五胶体164设置在显示屏120朝向支撑面1451的一侧表面上，通过在显示屏120与中板145之间设置第五胶体164，将显示屏120固定在中框140的中板145上。
另一方面，第五胶体164的第一端分别与第二胶体1621和第三胶体1622相连，可以避免第二胶体1621与第五胶体164之间形成缝隙，避免第三胶体1622与第五胶体164之间形成缝隙，使得环境中的水渍无法由第二胶体1621与第五胶体164之间的缝隙、与第三胶体1622与第五胶体164之间的缝隙进入到显示屏120与中板145之间，影响电子设备的正常使用。
其中，在本申请的一些实施例中，第四胶体163和第五胶体164的材质也可以为热熔胶。这样，当电子设备长期使用过程中，需要对电子设备内部进行维护时，只需要对第四胶体163进行加热，既可以将显示屏120与边框141分离，在对第五胶体164进行加热，将显示屏120与中框140分离，即可对电子设备的内部进行维护。
请继续参阅图10箭头所示的路径，由出音通道150进入，并且扩散至功能层123背离盖板121一侧的汗液与水渍，会被第五胶体164封堵，进一步地避免由出音通道150进入的水渍进入到电子设备的内部。这样，通过相互配合的第一胶体161、第二胶体1621、第三胶体1622、第四胶体163和第五胶体164，可以更好的保护电子设备。
在本申请的一些实施例中，请参阅图11，图11为本申请另一些实施例提供的中框的局部示意图。第一凸台1421与出音通道150之间设有第一避让空间143，第二凸台1422与出音通道150之间设有第二避让空间144。其中，第一凸台1421设置于出音通道150的一侧(例如图11中所示的出音通道150在X轴负方向的一侧)，第一凸台1421与出音通道150之间具有一定的距离不设置凸台，第一凸台1421与出音通道150之间的空间为第一避让空间143。
同理，第二凸台1422位于出音通道150的另一侧(例如图11中所示的出音通道 150在X轴正方向的一侧)，第二凸台1422与出音通道150之间具有一定的距离不设置凸台，第二凸台1422与出音通道150之间的空间为第二避让空间144。
需要说明的是，第一胶体、第二胶体和第四胶体在第一避让空间的位置连接，设置第一避让空间143，可以增加第一胶体、第二胶体和第四胶体在第一避让空间143的设置空间，继而增加第一胶体、第二胶体和第四胶体在第一避让空间143的量，进而可以增加第一胶体、第二胶体和第四胶体在第一避让空间143连接的稳定性，保证第一胶体、第二胶体和第四胶体之间密封性，避免外界环境中的水渍由第一胶体、第二胶体和第四胶体连接的位置进入到电子设备内部。
第一胶体、第三胶体和第四胶体在第二避让空间的位置连接，设置第二避让空间143，可以增加第一胶体、第三胶体和第四胶体在第二避让空间144的设置空间，继而增加第一胶体、第三胶体和第四胶体在第二避让空间144连接的稳定性，保证第一胶体、第三胶体和第四胶体之间的密封性，避免外界环境中的水渍由第一胶体、第三胶体和第四胶体连接的位置进入电子设备内部。
这样一来，一方面，设置第一避让空间143可以提高第二胶体1621、第一胶体161和第四胶体163之间的连接强度；设置第二避让空间143可以提高第三胶体1622、第一胶体161和第四胶体163之间的连接强度。另一方面，通过设置第一避让空间143和第二避让空间144，用户在使用电子设备时，可以避免用户由避让缺口看到凸台，进而提升电子设备整体美感，改善用户的使用体验。
在具体的点胶过程中，请参阅图12和图13，图12为本申请另一些实施例中第一胶体点胶至显示屏的示意图；图13为本申请另一些实施例中第二胶体、第三胶体和第四胶体点胶至中框的示意图。首先，将第一胶体161点胶至显示屏120上的相应位置；其次，将第二胶体1621和第三胶体1622点胶至中框140上的相应位置；再次，将第四胶体163点胶体中框140上的相应位置；最后，将显示屏120安装到中框140上。其中，显示屏120和中框140之间还设有第五胶体164。
由此，通过设置相互配合的第一胶体161、第二胶体1621、第三胶体1622、第四胶体163和第五胶体164，其中，第二胶体1621与第一胶体161相连接，第二胶体1621与第四胶体163相连接，第二胶体1621与第五胶体164相连接；第三胶体1622与第一胶体161相连接，第三胶体1622与第四胶体163相连接，第三胶体1622与第五胶体164相连接。进而全方位的保护电子设备，避免外界环境中的水分进入到电子设备的内部，避免电子设备内部的电子元器件遭受侵蚀。
在本说明书的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
