在阅读并理解了附图和详细描述后，可以明白其他方面。
附图概述
图1为相关技术中的音频输出器件的示意图；
图2为本实用新型实施例提供的一种电子设备的结构示意图；
图3为本实用新型实施例提供的电子设备中一种结构件的结构示意图；
图4为本实用新型实施例提供的电子设备中另一种结构件的结构示意图；
图5为本实用新型实施例提供的电子设备中一种柔性连接件与音频输出 器件的连接关系示意图。
本实用新型的实施方式
下文中将结合附图对本实用新型的实施方式进行详细说明。需要说明的是，在不冲突的情况下，本文中的实施例及实施例中的特征可以相互任意组合。
如图2所示，为本实用新型实施例提供的一种电子设备的结构示意图。本实施例提供的电子设备可以包括：电路板21、音频输出器件22和结构件23。
其中、音频输出器件22与电路板21电连接；结构件23设置在电路板21的外围，该结构件23设置有一容置腔2301，音频输出器件22密封于容置腔2301内。
可选地，本实施例在实施过程中，为了将音频输出器件22密封于容置腔2301内，如图3所示，为本实用新型实施例提供的电子设备中一种结构件的结构示意图，结构件23可以包括容置槽231和密封板232，密封板232与容置槽231的开口2311密闭地扣合，形成容置腔2301。此时，当密封板232与容置槽231扣合之后，可以在接缝处采用如超焊、点胶等方式固定密封板232和容置槽231，使得密封板232和容置槽231密闭，进而使得音频输出器件22具有一个密封性良好的音腔，避免漏音。
可选地，为了简化电子设备的结构，如图4所示，为本实用新型实施例提供的电子设备中另一种结构件的结构示意图，结构件23仅具有一容置槽231，上述容置槽231可以与音频输出器件22的尺寸相匹配，使得音频输出器件22放入容置槽231之后，该音频输出器件22的第一表面能够刚好卡合在容置槽231的开口2311处，这样，在音频输出器件22的第一表面的边缘与容置槽231之间的接缝处，便可以采用如超焊、点胶等方式固定上述第一表明的边缘和容置槽231，使得第一表面与容置槽231密闭，进而使得音频输出器件22具有一个密封性良好的音腔，避免漏音。
可选地，音频输出器件23可以与电路板21为有线或者无线连接。例如，当音频输出器件23与电路板21为有线连接时，电子设备可以还包括一柔性连接件，该柔性连接件的一端与音频输出器件22连接，该柔性连接件的另一端 与电路板21连接；当音频输出器件22与电路板21为无线连接时，电子设备还可以包括第一无线连接件和第二无线连接件，其中，第一无线连接件设置在电路板21上，第二无线连接件设置在音频输出器件22上，通过第一无线连接件和第二无线连接件之间的数据交互，实现音频输出器件22与电路板21的电连接。
在实际应用中，上述柔性连接件可以为普通排线、柔性电路板(Flexible Printed Circuit board，简称为：FPC)等，本实用新型不作具体限定。
举例来说，如图5所示，为本实用新型实施例提供的电子设备中一种柔性连接件与音频输出器件的连接关系示意图，音频输出器件22贴片于柔性连接件41，即FPC上，那么，对于如图3所示实施例中的结构件23，也就是说，当音频输出器件22通过容置槽231和密封板232密封时，密封板232上还可以开设一通孔，柔性连接件41可以从该通孔中穿出，然后，采用超焊或者点胶的方式将柔性连接件41固定于密封板232上，进一步密封容置腔2301。
可选地，本实用新型实施例为了避免音频输出器件22与其他音频器件引起啸叫，在上述一个或者多个实施例所述的电子设备中，可以在容置槽231的底部开设有一个出音孔，这样，当音频输出器件22发声时，声音就可以通过这个唯一的出音孔传播，不会与其他音频器件产生干扰，从而避免啸叫。
本领域技术人员应理解，说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本实用新型的至少一个实施例中。因此，在整个说明书中多处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外，这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。应理解，在本实用新型的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本实用新型实施例的实施过程构成任何限定。上述本实用新型实施例序号仅仅为了描述，不代表实施例的优劣。
在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过 程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
以上所述，仅为本实用新型的实施例和可选地实施方式，本实用新型的保护范围并不局限于上述实施例和可选地实施方式，对于本实用新型实施例所属技术领域的普通技术人员来说，在不脱离本实用新型实施例构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本实用新型实施例的保护范围。也就是说，本实用新型实施例的保护范围应以权利要求的保护范围为准。
工业实用性
本实用新型实施例的电子设备包括电路板、音频输出器件和结构件，其中，音频输出器件与电路板电连接，结构件设置在电路板的外围，该结构件设置有容置腔，该音频输出器件密封于该容置腔内；本实用新型实施例通过在固定电路板的结构件上专门为音频输出器件设置一容置腔，将音频输出器件密封于该容置腔中，以实现增强音频输出器件的密封性，避免漏音、啸叫等情况发生的技术效果。
