本申请要求在2022年10月20日提交中国专利局、申请号为202211289355.8、发明名称为“电子设备”的中国专利申请的优先权，该中国专利申请的全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种电子设备。
背景技术
相关技术中，电子设备的内部设有发声器件，且电子设备设有出音孔和出音通道，利用出音孔和出音通道，将发声器件的声波导出，实现发声。
随着电子设备的发展，对电子设备的外观要求越来越高，为提升电子设备的外观性能，电子设备的出音孔和出音通道的尺寸越来越小，这就导致用户在使用电子设备的过程中，容易因操作不当而堵住出音孔和出音通道，同样地，长期进尘也会堵塞出音孔和出音通道，导致产生杂音，使得发声效果变差。
发明内容
本申请实施例的目的是提供一种电子设备，能够解决相关技术中电子设备的出音孔被遮挡或封堵导致产生杂音的问题。
本申请实施例提供一种电子设备，包括设备主体和发声器件，所述发声器件设置于所述设备主体，所述设备主体设有导音通道、出音通道、主出音孔和辅助出音孔，所述发声器件的发声端朝向所述导音通道，所述导音通道通过所述出音通道分别与所述辅助出音孔和所述主出音孔连通，所述辅助出音孔邻近所述主出音孔设置，且所述辅助出音孔位于所述主出音孔远离所述 导音通道的一侧。
在本申请实施例中，设备主体设有辅助出音孔和主出音孔，在主出音孔未被封堵的情况下，由于辅助出音孔位于主出音孔远离导音通道的一侧，即声音流入辅助出音孔的阻力要大于流入主出音孔的阻力，故发声器件发出的大部分声音通过出音通道由主出音孔发声；在至少部分主出音孔被封堵的情况下，此时声音流经主出音孔的声阻增大，相比之下，声音更易从出音通道进入辅助出音孔，通过辅助出音孔实现正常发声，避免产生杂音；而且，由于辅助出音孔邻近主出音孔设置，辅助出音孔的发声区域与主出音孔的发声区域基本相同，故不易出现漏音问题，避免在主出音孔被封堵时声音流向其它区域而导致漏音。

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 清楚地描述，显然，所描述的实施例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获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的电子设备进行详细地说明。
请参考图1-图6，本申请实施例公开的电子设备包括设备主体100和发声器件200，设备主体100作为发声器件200的安装基础，发声器件200设置于设备主体100，可选地，发声器件200设置于设备主体100的内部。设备主体100设有导音通道111、出音通道112、主出音孔113和辅助出音孔114，其中，发声器件200的发声端朝向导音通道111，以使发声器件200发出的声音信号能够直接进入导音通道111；导音通道111通过出音通道112分别与辅助出音孔114和主出音孔113连通，那么，导音通道111内的声音信号能够通过出音通道112分别由辅助出音孔114和主出音孔113流出。
辅助出音孔114邻近主出音孔113设置，且辅助出音孔114位于主出音孔113远离导音通道111的一侧，即沿出音通道112的延伸方向，辅助出音孔114与导音通道111之间的距离大于主出音孔113与导音通道111之间的距离。可选地，辅助出音孔114和主出音孔113可以均延伸至出音通道112的侧壁，或者，主出音孔113延伸至出音通道112的侧壁，且辅助出音孔114延伸至出音通道112远离导音通道111的一端。当然，本申请对导音通道111、 出音通道112、辅助出音孔114和主出音孔113的结构不做具体限制，能够实现对应的功能即可。
在本申请实施例中，设备主体100设有辅助出音孔114和主出音孔113，在主出音孔113未被封堵的情况下，由于辅助出音孔114位于主出音孔113远离导音通道111的一侧，即声音流入辅助出音孔114的阻力要大于流入主出音孔113的阻力，故发声器件200发出的大部分声音通过出音通道112由主出音孔113发声；在至少部分主出音孔113被封堵的情况下，此时声音流经主出音孔113的声阻增大，相比之下，声音更易从出音通道112进入辅助出音孔114，通过辅助出音孔114实现正常发声，避免产生杂音。
参考图4和图5的气流示意图可知，在主出音孔113未被封堵的情况下，流经辅助出音孔114的气流较少，气流主要从主出音孔113流出；在至少部分主出音孔113被封堵的情况下，流经辅助出音孔114的气流增多，说明声音信号更易从出音通道112进入辅助出音孔114，通过辅助出音孔114实现正常发声，避免产生杂音。
而且，由于辅助出音孔114邻近主出音孔113设置，辅助出音孔114的发声区域与主出音孔113的发声区域基本相同，故不易出现漏音问题，避免在主出音孔113被封堵时声音流向其它区域而导致漏音。参考图6所示的漏音性能随频率的变化曲线，可知，在至少部分主出音孔113被封堵的情况下，相关技术中未设置辅助出音孔114的电子设备和本申请设置辅助出音孔114的电子设备，二者在低频段的漏音一致性较高，说明设置辅助出音孔114并不会增大漏音性能，有利于保证发声效果。
在可选的实施例中，辅助出音孔114直接与导音通道111的一端连通，或者，如图1-图2所示，出音通道112远离导音通道111的一端还设有辅助导音腔300，辅助出音孔114开设于与辅助导音腔300对应的设备主体100的表面，即辅助出音孔114通过辅助导音腔300与出音通道112连通。在至少部分主出音孔113被封堵的情况下，出音通道112的声音信号流入辅助导 音腔300，进一步声音信号由辅助出音孔114流出。在出音通道112的延伸方向与辅助出音孔114的轴线方向不一致的情况下，若出音通道112与辅助出音孔114直接连通，声音信号需急速转换方向，才能从辅助出音孔114流出，故设置辅助导音腔300，方便声音信号在辅助导音腔300内进行过渡，有利于出音通道112的声音信号及时转换方向，从而顺利由辅助出音孔114流出。
在可选的实施例中，辅助导音腔300的过流面积小于出音通道112的过流面积，或者，辅助导音腔300的过流面积大于出音通道112的过流面积。可选地，辅助导音腔300的过流面积和出音通道112的过流面积均指在第一平面的截面积，第一平面垂直于出音通道112的延伸方向。后一实施例与前一实施例相比，在主出音孔113的至少部分被封堵的情况下，声音信号由出音通道112流入辅助导音腔300的阻力减小，有利于声音信号顺利流向辅助出音孔114，最终顺利由辅助出音孔114流出，避免声音信号流入辅助导音腔300的阻力增大，导致声音信号仍旧主要流经主出音孔113进而产生杂音。
在可选的实施例中，辅助导音腔300的顶壁的位置低于出音通道112的顶壁的位置，如此，辅助导音腔300与出音通道112的连接处的过流面积小于出音通道112的过流面积，也就是说，声音信号由出音通道112流向辅助导音腔300的过程中，阻力会增大，不利于声音信号顺利从辅助导音腔300和辅助出音孔114流出。在另一种实施例中，辅助导音腔300的顶壁与出音通道112的顶壁平齐。如此，辅助导音腔300与出音通道112的连接处的过流面积不会小于出音通道112的过流面积，故声音信号由出音通道112流向辅助导音腔300的过程中，阻力恒定或阻力减小，有利于声音信号顺利从辅助导音腔300和辅助出音孔114流出。此外，辅助导音腔300的顶壁与出音通道112的顶壁平滑过渡，也可以降低声信号传输过程中的阻力。
在可选的实施例中，导音通道111与出音通道112相连的一端的过流面积小于或等于出音通道112的过流面积，或者，导音通道111与出音通道112 相连的一端的过流面积大于出音通道112的过流面积。在后一实施例中，声音信号由导音通道111与出音通道112的连接处流向出音通道112的过程中，过流面积减小，声音信号的流速增大，有利于声音信号及时地主要从主出音孔113流出，并在主出音孔113的至少部分被封堵的情况下，声音信号也能够及时从辅助出音孔114流出。
一种可选的实施例中，设备主体100包括边框110，辅助出音孔114开设于边框110，出音通道112的延伸方向与边框110的延伸方向不一致，导音通道111相对于出音通道112弯折，主出音孔113延伸至出音通道112的侧壁。在另一种实施例中，出音通道112沿边框110的延伸方向延伸。如此，边框110可以沿自身的延伸方向开设出音通道112，有利于简化工艺，而且，出音通道112不会在边框110的厚度方向上占用边框110过多的空间，有利于实现电子设备的轻薄化。
在可选的实施例中，主出音孔113可以为圆形通孔，或者，主出音孔113为出音缝隙，出音通道112为条形出音槽，出音缝隙与条形出音槽相对且连通。采用本实施例，条形出音槽和出音缝隙均为条状结构，既能增大主出音孔113的出音面积，又能保持声音信号优先从出音缝隙流出，有利于扩大主出音孔113的发音区域。可选地，条形出音槽的延伸方向与出音缝隙的延伸方向一致，且条形出音槽的第一端与出音缝隙的第一端相对，辅助导音腔300与出音缝隙的第二端相对，如此，尽可能地增大出音缝隙的长度，有利于扩大主出音孔113的发音区域。
在可选的实施例中，设备主体100还包括显示模组120，显示模组120设置于边框110的中部区域，且边框110为一体式结构，边框110开设有辅助出音孔114和出音缝隙，且边框110内设有与出音缝隙连通的条形出音槽。在另一种实施例中，如图1所示，边框110为分体式结构，边框110包括第一框部a和第二框部b，显示模组120设置于第一框部a，辅助出音孔114设置于第二框部b，且第一框部a与第二框部b之间设有出音缝隙，在第一框 部a和第二框部b安装在一起之后，第一框部a的表面和第二框部b的表面形成条形出音槽和出音缝隙。如此，第一框部a和第二框部b的表面设置对应的结构，即可使二者连接之后直接形成出音缝隙和条形出音槽，无需再单独开设出音缝隙和条形出音槽，有利于降低工艺要求。
在可选的实施例中，边框110沿自身的延伸方向设置至少两个辅助出音孔114，最靠近主出音孔113的辅助出音孔114与主出音孔113在边框110的延伸方向上的距离大于或等于预设值，说明辅助出音孔114与主出音孔113的距离较远；或者，最靠近主出音孔113的辅助出音孔114与主出音孔113在边框110的延伸方向上的距离小于预设值，说明辅助出音孔114与主出音孔113的距离较近，辅助出音孔114的发声区域与主出音孔113的发声区域之间的距离也较近。在后一实施例中，电子设备不易出现漏音问题，避免在主出音孔113被封堵时声音流向其它发声区域而导致漏音。可选地，预设值可以为稍大于零的值。
在可选的实施例中，边框110沿自身的延伸方向设置至少两个辅助出音孔114，在电子设备的厚度方向上，各辅助出音孔114的正投影位于主出音孔113的正投影之外。在另一种实施例中，主出音孔113的正投影与至少一个辅助出音孔114的正投影重合。可选地，主出音孔113为出音缝隙，在电子设备的厚度方向上，出音缝隙的正投影与至少一个辅助出音孔114的至少部分正投影重合。采用本实施例，在电子设备的厚度方向上，主出音孔113的发声区域与各辅助出音孔114形成的发声区域至少部分重合，说明辅助出音孔114距离主出音孔113较近，电子设备不易出现漏音问题，避免在主出音孔113被封堵时声音流向其它区域而导致漏音。
在进一步的实施例中，至少两个辅助出音孔114位于出音缝隙的正上方或正下方，即在电子设备的厚度方向上，出音缝隙的正投影与各辅助出音孔114的正投影相重合，从而进一步防止漏音。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上 述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
