Description

电子终端 技术领域
本发明涉及电子终端技术领域，特别涉及一种电子终端。
背景技术
现有的电子终端(例如但不限于手机、IPAD等)中，其内部通常仅设置一个发声器件，且该发声器件通过导声管与电子终端外壳上的出声孔连通，以将声音导出。然而，发声器件所发出的声音在导声管内传导的过程中，通常会产生较大的音量衰减，从而导致电子终端的响度较低，影响用户体验。

本发明提出一种电子终端。
参照图1至图4，在本发明一实施例中，该电子终端包括：
外壳，具有一出声孔11；
至少两个发声器件20，设于外壳内；以及
导声管结构，连通各发声器件20与出声孔11。
不失一般性，本实施例中，该出声孔11可以是一个整体的大孔，且为避免颗粒杂质等污染物从出声孔11进入外壳内，作为整体大孔的出声孔11中盖设有滤网。然本设计不限于此，于其他实施例中，该出声孔11也可以由一微孔群所构成。
本发明的技术方案中，电子终端内装配有两个或以上的发声器件20，并通过导声管结构将各发声器件20与电子终端的出声孔11连通，如此，可通过多个发声器件20的协同工作来弥补导声管结构所导致的音量衰减，从而提升该电子终端的声音响度。
不失一般性，本实施例中，该电子终端的外壳包括后盖101、连接于后盖周缘的边框102，及连接于边框102的前壳103。后盖101与前壳103相对设置，为便于用户通话时听到声音，出声孔11可以设于前壳103的上部(见图2)，而导声管结构的设置，则可使得发声器件20的位置选择更为方便。
或者，出声孔11并不设于前壳103上，而是设置在边框102与前壳103之间结合的缝隙处，此时外壳包括后盖101、连接于后盖周缘的边框102，及连接于边框102的前壳103。后盖101与前壳103相对设置，前壳103与边框102间形成有透气缝隙，透气缝隙为出声孔11，如图8所示。此时本结构更适用于电子终端的全面屏结构或者屏占比高的设备。
进一步的，上述前壳103与边框102之间形成透气缝隙，可以是前壳103上形成避让部分，以便在与边框102结合时前壳103的避让部分形成透气缝隙，也可以是边框102上形成避让部分，以便在与前壳103结合时边框102的避让部分形成透气缝隙，还可以是前壳103及边框103都有避让部分，此时在前壳103与边框102结合时，由前壳103及边框103的避让部分形成透气缝隙，如图9所示。
进一步的，上述电子终端可以是全面屏手机或者屏占比高的手机，或者IPAD等电子设备，本发明对此不做限制。
进一步的，上述后盖101与边框103可以是一体成型的结构，此时边框 102与后盖101之间并没有明显的缝隙结构，使得电子终端更为美观。当然，后盖101与边框102也可以是分体结构，本发明对此不做限制。
在本实施例中，参照图4，进一步地，导声管结构设置为一整体的导声管31，该导声管31对应每一发声器件20设有一导声入口，并对应出声孔11设有一导声出口，如此，可使得各发声器件20所发出的声音均能进入导声管31，并由导声管31传导至出声孔11。可以理解，将导声管结构设置为一整体的导声管31，只需要一次安装动作即可将导声管结构装配完毕，有利于产品装配效率的提升。
本实施例中，可选地，该至少两个发声器件20完全相同，如此，一方面可获得较好的响度提升效果，另一方面有利于发声器件20的规模采购，从而有利于产品成本的降低。然本设计不限于此，于其他实施例中，该至少两个发声器件20也可以是不相同的，其可以是外形尺寸不同，也可以是所发出的声音频率不同。例如在电子终端包含两个发声器件20时，其外形尺寸不同，参照图7。特别地，该至少两个发声器件20中的一个可以为低频发声器件(其所发出的声音注重低频)，其他的则可以为中频发声器件(其所发出的声音注重中频)或高频发声器件(其所发出的声音注重高频)，如此，至少两个发声器件20所发出的声音叠加，可获得改善整机音质的效果。当然，上述至少两个发声器件20也可以都是低频发声器件，或者都是中频发声器件，或者都是高频发声器件，本发明对此不做限制。
可选地，该电子终端上发声器件20所采用的是动圈式发声器件，动圈式发声器件的效率较高，且可靠耐用。然本设计不限于此，于其他实施例中，该电子终端上的发声器件20还可采用发射超声波的超声传感器等，本发明对此不作限制。
本实施例中，进一步地，该至少两个发声器件20的工作状态均可独立控制；即是说，该至少两个发声器件20可同时工作，也可以仅控制其中一个发声器件20进行工作。可以理解，单一发声器件20工作，可节省电量，在环境噪声较低而响度要求不高、或者需要更好的声音私密性而不需要高响度时，可仅控制其中一个工作；而同时工作，则可获得更高的响度。需要说明的是，本实施例中，既可以从通断供电的方式，也可以从通断信号的方式，进行发声器件20的工作状态控制。
在本实施例中，进一步地，发声器件20的数量为两个，且该两个发声器件20分设于出声孔11的相对两侧，如此，有利于使电子装置获得效果良好的立体声。
可选地，出声孔11设于前壳103上部的中部位置，以利于用户在通话时，对准耳朵，从而便于听到清晰的声音。
参照图5，图5为本发明电子终端另一实施例的结构示意图。一并参照图6，该实施例与前述实施例的不同之处在于，在该电子终端中，导声管结构包括至少两导声子管32，每一导声子管32的一端连通一发声器件20设置，另一端连通所述出声孔11。如此，亦可通过该导声管结构，使得各发声器件20所发出的声音能传导至出声孔11。
本实施例中，可选地，不同的导声子管32连通出声孔11的不同区域。如此，不同的发声器件20所发出的声音通过各自对应的导声子管32进行传导，并从出声孔11的不同区域传到外部，如此，即使出声孔11上对应一导声子管32的区域被堵塞，只要对应另一导声子管32的区域未被堵塞，则仍可听到声音，提高了该电子终端的发声可靠性。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
