具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行详细描述。需要说明的是，在不冲突的情况下，本申请的实施方式及实施方式中的特征可以相互组合。在下面的描述中阐述了很多具体细节以便于充分理解本申请，所描述的实施方式仅仅是本申请一部分实施方式，而不是全部的实施方式。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本申请。本文所使用的术语“和/或”包括一个或多个相关的所列项目的所有的和任意的组合。
在本申请的各实施例中，为了便于描述而非限制本申请，本申请专利申请说明书以及权利要求书中使用的术语“连接”并非限定于物理的或者机械的连接，不管是直接的还是间接的。“上”、“下”、“上方”、“下方”、“左”、“右” 等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也相应地改变。
本申请实施例提供的一种终端装置的结构示意图。终端装置可以是手机、智能手表、手环、平板电脑、笔记本电脑、行车记录仪、可穿戴设备、对讲机、蓝牙耳机、蓝牙音箱等具有音频功能的电子产品。请参阅图2，在本实施例中，以终端装置为手机100进行说明。为便于说明，定义手机100的厚度方向为Z轴方向、短边方向为X轴方向、长边方向为Y轴方向，X轴方向与Y轴方向所确定的平面为XY平面。
请一并参阅图3以及图4，为图2所示的手机100的爆炸图。为实现终端装置的音频功能，终端装置可以包括听筒50、麦克风60和/或扬声器70等用于音频功能的声学元件15。终端装置中声学元件15的数量至少为一个，在具体实施例中，听筒50、麦克风60以及扬声器70等声学元件15的数量均可以根据需要进行设置，可以为一个或多个，在一些实施例中还可以根据需要省略。例如，终端装置为手机100时，手机100中可以同时设置听筒50、麦克风60以及扬声器70，终端装置为平板电脑时，平板电脑中可以设置麦克风60以及扬声器70，即平板电脑中可以无需设置听筒50。听筒50、麦克风60以及扬声器70等声学元件15在终端装置中的位置也可以根据实际需要进行设置，例如，在一些实施例中，以手机100为例，听筒50通常设置于靠近摄像头的一侧，即手机100的头部，麦克风60可以设置于背离摄像头的一侧，即手机100的底部。可以理解，上述仅为举例说明，并不以此为限制。
终端装置还包括至少两个结构件10，结构件10位于终端装置的外表面，至少两个结构件10相互结合形成腔体11(请参阅图5)，腔体11可以用于容置听筒50、麦克风60以及扬声器70等声学元件15，腔体11还可以用于容置其他的元件，例如电池、电路板等。其中，相邻的两个结构件10之间形成至少一出音缝13，终端装置内部还设置有导音缝，导音缝与出音缝13连通，声学元件15可以通过导音缝以及出音缝13与外界实现声音的传递。在相邻的两个结构件10之间设置出音缝13，无需在结构件10上开孔，有效保证结构件10的完整性，提升终端装置的精致度以及外观竞争力；另外，出音缝13的最小宽度相较于孔的最小直径要小，有效减小外界杂质(例如水、灰尘等)进入终端装置内部的可能性，在一些实施例中，出音缝13的宽度可以为0.1mm-0.5mm，例如0.2mm、0.3mm、0.4mm等，小于相关技术中孔的直径，从而有效减小或避免灰尘或水分等杂质进入终端装置内部；两个结构件10之间形成出音缝13的制作工艺，相较于形成孔的工艺简单，所需要克服的结构件10的应力较小，且便于对缝进行表面处理以形成光滑的表面，更加便于成型结构件10。
在一些实施例中，终端装置包括相互固定的三个结构件，为便于说明，将终端装置的三个结构件10分别定义为第一结构件、第二结构件以及第三结构件，第一结构件、第二结构件以及第三结构件为单独的三个部分，即第一结构件、第二结构件以及第三结构件不是一体成型，可以通过粘结、卡接等 方式固定成一整体。

显示屏20可以是有机发光二极管(Organic Light-Emitting Diode，OLED)显示屏20，也可以为液晶显示屏(Liquid Crystal Display，LCD)。显示屏20可以包括显示器和触控器件，显示器用于向用户输出显示内容，触控器件用于接收用户在显示屏20上输入的触摸事件。
壳体40的材质可以是金属、玻璃、塑料、陶瓷等或者上述材质的组合，具体材质种类并不限制。在本实施例中，壳体40为电池壳，在其他实施例中，壳体40并不限于电池壳，可以根据终端装置的具体种类设置。

在需要设置听筒50、麦克风60、扬声器70的区域内的背胶21在XY平面内朝向背离边框31的方向凹陷(请参阅图3或图4)，即环状的背胶21 朝向环状中心凹陷，以预留部分区域设置听筒50、麦克风60以及扬声器70，以避免背胶21阻挡用于传递声音的通道，从而影响出音或拾音效果；另外，环状的背胶21围设于导音缝以及出音缝13的周缘从而密封导音缝以及出音缝13，以使声音在导音缝以及出音缝13中传递，避免声音进入手机100内部而影响出音或拾音效果。
壳体40与中框30固定连接。在本实施例中，壳体40与中框30也通过背胶(图未示)固定连接，从而将壳体40固定于第二凹槽34中。在其他实施例中，壳体40与中框30也可以通过点胶工艺或者点胶工艺与背胶21结合进行固定连接。

沿Z轴方向大致与听筒50对应区域的中板32与显示屏20间隔设置形成第一导音缝91，上边框部311与显示屏20间隔设置形成第一出音缝131，即第一出音缝131位于手机100的外观面，上边框部311与显示屏20未设置第一出音缝131的区域连接，第一导音缝91沿X轴方向延伸，形成细长的狭缝，第一出音缝131位于相邻的两个结构件10之间，第一导音缝91与第一通孔321以及第一出音缝131连通，共同形成第一通道A，其中，听筒50发声，经过第一通道A(即第一通孔321、第一导音缝91以及第一出音缝131)，从而将听筒50发出的声音传递到手机100的外部。
具体地，在本实施例中，中板32临近边框31、设置听筒50并朝向显示屏20的表面沿Z轴方向朝向背离显示屏20的方向凹陷，以使中板32与显示屏20间隔设置，从而形成第一导音缝91。第一导音缝91可以由中板32和/或显示屏20凹陷形成。

请参阅图2、图5和图6，在XY平面内，第一出音缝131同时与第一导音缝91以及第二导音缝92均相互连通，即第一通道A与第二通道B共用第一出音缝131。在一些实施例中，第一通道A与第二通道B也可以不共用第一出音缝131。
请参阅图7，在一些实施例中，中框30还包括阻挡部35，阻挡部35设置于第一凹槽33所在一侧，阻挡部35设置于中板32与上边框部311相互连 接的区域，且位于第一导音缝91以及第二导音缝92之间，阻挡部35用于间隔第一导音缝91以及第二导音缝92，降低声音通过第一通道A与第二通道B时的相互干扰。

请参阅图11，图11为图10沿C’-C’方向的截面示意图。中板32上设置有第五导音缝95，第五导音缝95为通孔，第五导音缝95贯穿中板32以及下边框部313，第一部36a与第二部37a围设形成第五导音缝95，第五导音缝95为弯曲状，第五导音缝95的一端靠近扬声器70并与扬声器70连通。第一部36a通过胶体38a与壳体40连接，第二部37a沿Y轴方向朝向背离壳体40的方向凹陷，以使第二部37a与壳体40间隔设置，从而形成第三出音缝133，第三出音缝133位于手机100a的外观面，第三出音缝133沿X轴方向延伸，形成细长的狭缝，第三出音缝133位于相邻的两个结构件10之间，第三出音缝133与第五导音缝95连通共同形成第五通道E，其中，扬声器70发出的声音通过第五通道E(即弯曲状的第五导音缝95、第三出音缝133)传递至手机100a的外部。可以理解，胶体38a连接中框30与壳体40，在能够实现第三出音缝133的功能的前提下，可以减小或避免外界杂质(例如灰尘、水等)进入壳体40与中框30之间而污染手机100a的内部元件。
请参阅图12，图12为图10沿D’-D’方向的截面示意图。沿Z轴方向大致与第二麦克风63对应区域的中板32上设置有第三通孔323，第三通孔323与第二麦克风孔822连通；下边框部313开设有第四通孔324并延伸至壳体40所在区域，且中板32与显示屏20间隔设置并与第四通孔324连通共同形成第六导音缝96，第一部36a与第二部37a围设形成第六导音缝96的一部分，即在本实施例中，第六导音缝96由中框30与显示屏20之间间隔设置的空间以及贯穿中板32与下边框部313的第四通孔324两部分组成。第二部37a与壳体40间隔设置形成的第三出音缝133还延伸至第二麦克风63所在区域，从而使得第三出音缝133与第六导音缝96连通，第二麦克风孔822、第三通孔323、第六导音缝96以及第三出音缝133相互连通形成第六通道F，外界声音可以通过第六通道F(即第三出音缝133、第六导音缝96、第三通孔323以及第二麦克风孔822)，从而将外界的声音传递至第二麦克风63以实现拾音。
请参阅图13，在一些实施例中，中框30还可以包括阻挡部35b，阻挡部35b设置于第二凹槽34所在一侧，阻挡部35b设置于中板32以及下边框部313相互连接的区域，且位于第五导音缝95以及第六导音缝96之间，阻挡部35b用于间隔第五导音缝95以及第六导音缝96，降低声音通过第五通道E与第六通道F时的相互干扰。
当出音缝13(例如第三出音缝133)位于壳体40所在一侧时，由于用户在使用手机100a的过程中，通常是显示屏20朝向用户，当出音缝13位于手机100a的壳体40所在一侧时，用户更加难以发现位于背面(即壳体40所在一侧)的出音缝13，进一步提升手机100a的精致度以及外观竞争力。终端装置可以采用屏幕发声(即显示屏发声)。例如，请参阅图14和图15，手机100a还可以包括激励器23，激励器23固定于显示屏20上并位于腔体11中，激励器23与中框30以及电路板80(例如第一电路板81)均间隔设置，中框30上可以设置用于容置激励器23的避让槽39以使激励器23与中框30 间隔设置。激励器23可以是压电陶瓷、动圈磁铁等。在一些实施例中，例如出音缝13设置于壳体40所在一侧时，由于用户在使用手机100a时，例如打电话、看视频等，通常是屏幕所在一侧朝向用户，出音缝13设计于壳体40所在一侧，声音从壳体40一侧传出，较难保证使用效果，当采用与屏幕发声相结合时，在不影响用户使用效果时，能够提升手机100a的精致度以及外观竞争力。
可以理解地，用于听筒50以及第一麦克风61的声音传递的通道并不仅限于设置于显示屏20所在的一侧，也可以设置于壳体40所在一侧，即在壳体40所在一侧设置第四出音缝(图未示)，具体设置结构可以第一通道A以及第二通道B的结构设计，这里不再赘述。
在一些实施例中，与同一声学元件15相连通的通道并不仅限于一个，也可以为多个，用于同一声学元件15的声音传递的通道并不仅限于设置于显示屏20所在的一侧，或者壳体40所在一侧，可以在显示屏20所在一侧以及壳体40所在一侧均设置出音缝13。具体地，请参阅图16，本申请一些实施例提供一种手机100b的截面示意图。在本实施例中，手机100b同时包括第二出音缝132b以及第三出音缝133b，中框30上可以设置具有分叉结构的第七导音缝97，第七导音缝97的起点朝向扬声器70的振膜，第七导音缝97的终点一端朝向显示屏20，另一端朝向壳体40。具有分叉结构的第七导音缝97并不仅限于与扬声器70相互连通，也可以是其他声学元件15，即多个出音缝可以供应同一导音缝，则同一个声学元件15可以实现从多个出音缝实现出音或拾音，提升声学元件15出音或拾音的效果。
可以理解，用于听筒50以及第一麦克风61的声音传递的通道并不仅限于设置于显示屏20所在的一侧，或者壳体40所在一侧，可以在显示屏20所在一侧以及壳体40所在一侧均设置出音缝13，即终端装置可以同时包括第一出音缝131以及第四出音缝。
在一些实施例中，手机100的显示屏20可以为平面显示屏，例如显示屏20均位于XY平面内，在其他实施例中，显示屏20也可以为曲面显示屏(包括但不限于双曲面屏、四曲面屏等)。
请参阅图17以及图18，图17为本申请一些实施例提供的手机100c的显示屏20为曲面显示屏的整体结构示意图，图18为图17所示的手机100c的截面示意图。手机100c包括第一表面16、第二表面17以及侧面18，侧面18连接第一表面16以及第二表面17，第一表面16、第二表面17以及侧面18围设形成手机100c的外表面。第一表面16为显示屏20所在一侧，第二表面17为壳体40所在一侧，由于显示屏20为曲面，显示屏20还弯曲至侧面18，即显示屏20的表面包括第一表面16以及部分侧面18，剩余部分的侧面18可以为中框30的表面。其中，出音缝13可以设置在显示屏20与中框30之间，即出音缝13位于手机100c的侧面18，由于用户在使用手机100c的过程中，通常是显示屏20朝向用户，当出音缝13位于手机100c的侧面18时，用户更加难以发现位于侧面18的出音缝13，进一步提升手机100c 的精致度以及外观竞争力。
请参阅图19，在一些实施例中，出音缝13设置于手机100d的侧面18时，出音缝13也可以位于中框30与壳体40之间，即壳体40为曲面，壳体40弯曲至侧面18。其中，壳体40弯曲至侧面18且出音缝13位于中框30与壳体40之间时，显示屏20可以是平面显示屏或者曲面显示屏。
在一些实施例中，麦克风60、听筒50、扬声器70等声学元件15的相对位置以及与显示屏20、中框30以及壳体40的相对位置并不限于上述结构，可以根据需要进行调整。请参阅图20，在本实施例中，听筒50位于中板32与显示屏20之间并固定于第二电路板82上，用于与听筒50连通的导音缝以及出音缝13位于壳体40与中框30之间。
扬声器70的数量并不仅限于一个，还可以为多个(即大于或等于两个)，以便于提供更加真实的立体声效果。用于与扬声器70连通的出音缝13的数量与扬声器70的数量可以相同，也可以不同，出音缝13的位置可以根据需要实现的立体声效果进行设置。
在一具体实施例中，请参阅图21以及图22，以手机100e的扬声器70的数量为四个为例，用于与扬声器70连通的出音缝13的数量为四个。其中两个扬声器70位于手机100的一端，另外两个扬声器70位于手机100e的另一端；其中两个出音缝13位于显示屏20所在一侧，另外两个出音缝13位于壳体40所在一侧，四个扬声器70分别通过不同的出音缝13实现声音传递，则手机100的立体声效果更佳出色。在一些实施例中，还可以根据需要设计屏幕发声。
在一具体实施例中，请参阅图23，以手机100f的扬声器70的数量为四个为例，用于与扬声器70连通的出音缝13的数量为两个。其中两个扬声器70位于手机100f的一端，另外两个扬声器70位于手机100f的另一端；出音缝13均位于显示屏20所在一侧，每两个扬声器70共用一个出音缝13。在一些实施例中，还可以根据需要设计屏幕发声。
在一具体实施例中，请参阅图24，以手机100g的扬声器70的数量为四个为例，用于与扬声器70连通的出音缝13的数量为两个。其中两个扬声器70位于手机100g的一端，另外两个扬声器70位于手机100g的另一端；出音缝13均位于壳体40所在一侧，每两个扬声器70共用一个出音缝13。在一些实施例中，还可以根据需要设计屏幕发声。
在一些实施例中，请参阅图25，麦克风60的数量并不仅限于两个，还可以为多个，麦克风60的位置可以根据需要进行设置，例如，设置于手机100h的四周。
本申请实施例提供的终端装置(例如手机100、100a、100b、100c、100d、100e、100f、100g、100h)，在相邻的两个结构件10之间设置出音缝13，无需在结构件10上开孔，有效保证结构件10的完整性，提升终端装置的精致度以及外观竞争力；另外，出音缝13的最小宽度小于相关技术中孔的直径，从而有效减小或避免灰尘或水分等杂质进入终端装置内部；两个结构件10 之间形成出音缝13的制作工艺，相较于形成孔的工艺简单，所需要克服的结构件10的应力较小，且便于对缝进行表面处理以形成光滑的表面，更加便于成型结构件10。
以上实施方式仅用以说明本申请的技术方案而非限制，尽管参照以上较佳实施方式对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或等同替换都不应脱离本申请技术方案的精神和范围。
