背景技术
随着技术的进步以及用户需求的提升，电子设备的声学性能持续在优化。我们知道，电子设备的通话功能是其基本功能。在使用的过程中，用户手持电子设备进行通话。例如，在较为嘈杂的环境中，为了能够进行较为清楚的通话，目前的电子设备通常配置有至少两个发声器件(例如受话器)，在此种情况下，用户能够将电子设备的音量较大程度地调大。在此种情况下，周围的人也会听到电子设备发出的声音，进而会听到通话内容。很显然，这会导致用户的隐私泄露。
为了避免隐私泄露，用户往往不得已将音量调小，这又导致较难进行清楚地通话。很显然，目前的电子设备在进行通话时存在无法兼顾通话安全性及清楚通话的问题。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
以下结合附图，详细说明本发明各个实施例公开的技术方案。
请参考图1～图7，本发明实施例公开一种电子设备，所公开的电子设备包括设备主体100、第一发声器件200和第二发声器件300。
设备主体100为电子设备的主体部分。在通常情况下，设备主体100包括电子设备的主要构成器件，例如，设备主体100可以包括设备壳体以及安装于设备壳体的显示屏100c、电池、主板等功能器件。在本发明实施例中，设备主体100开设有第一出音孔110、第二出音孔120、第一安装腔130、第二安装腔140、第一导音通道150、第二导音通道160和第三出音孔170。
在本发明实施例中，第二出音孔120和第三出音孔170的朝向与第一出音孔110的朝向不同，第二出音孔120和第三出音孔170的朝向可以相同，也可以不同。具体地，第一出音孔110可以位于设备主体100的第一侧，第二出音孔120和第三出音孔170可以位于设备主体100的第二侧。
第一发声器件200和第二发声器件300为电子设备能够产生声音的器件，例如，第一发声器件200和第二发声器件300均可以是受话器。在第一发声器件200和第二发声器件300工作的过程中，第一发声器件200产生的声音，能够通过第一出音孔110和第二出音孔120传输至电子设备所处的环境中。第二发声器件300产生的声音，能够通过第一出音孔110和第三出音孔170传输至电子设备所处的环境中。
第一发声器件200设置于第一安装腔130内，从而实现与设备主体100之间的装配。第一发声器件200将第一安装腔130分隔成第一子腔131和第二子腔132。第一子腔131和第二子腔132密封隔离。第一子腔131与第一出音孔110连通，第二子腔132通过第一导音通道150与第二出音孔120连通。
在第一发声器件200工作的过程中，第一发声器件200产生的声音会依次通过第一子腔131和第一出音孔110后传输至电子设备所处的环境中，第一发声器件200产生的声音会依次通过第二子腔132和第二出音孔120后传输至电子设备所处的环境中。
第二发声器件300设置于第二安装腔140内，从而实现与设备主体100之间的装配。第二发声器件300将第二安装腔140分隔成第三子腔和第四子腔。第三子腔和第四子腔密封隔离。第三子腔与第一出音孔110连通，第四子腔通过第二导音通道160与第三出音孔170连通。
同理，在第二发声器件300工作的过程中，第二发声器件300产生的声音会依次通过第三子腔和第一出音孔110后传输至电子设备所处的环境中，第二发声器件300产生的声音会依次通过第四子腔和第三出音孔170后传输至电子设备所处的环境中。
第一导音通道150和第二导音通道160均为能够传导声音的通道。第一导音通道150能够调节从第二出音孔120传出的第二声波的相位，第二导音 通道160能够调节从第三出音孔170传出的第三声波的相位，从而使得第二出音孔120传出的第二声波以及第三出音孔170传出的第三声波均满足后文所述的要求。
第一发声器件200通过第一出音孔110发出的声波为第一声波，第二发声器件300通过第一出音孔110发出的声波为第四声波，第一发声器件200通过第二出音孔120发出的声波为第二声波，第二发声器件300通过第三出音孔170发出的声波为第三声波。在本发明实施例中，第二声波与第一声波的相位不同，第三声波与第四声波的相位不同，从而能够使得第二声波与第一声波相遇后以及第三声波与第四声波相遇后产生一定的抵消，从而促进声音在传播过程中的衰减。
本发明实施例公开的电子设备对现有的电子设备的结构进行改进，通过在设备主体100的第一侧开设有第一出音孔110以及在设备主体100的第二侧开设第二出音孔120和第三出音孔170，并使得第一发声器件200将第一安装腔130分隔成第一子腔131和第二子腔132，同时使得第二发声器件300将第二安装腔140分隔成第三子腔和第四子腔，第一导音通道150能够改变从第二出音孔120发出的第二声波的相位，从而使得第二声波与第一声波的相位不同，第二导音通道160能够改变从第三出音孔170发出的第三声波的相位，同时使得第三声波与第四声波的相位不同，在第一声波与第二声波相遇以及第三声波和第四声波相遇时均能够达到一定的声波抵消效果，从而能够有效地降低声音泄漏量。声音泄漏量的降低，使得用户在使用电子设备进行通话的过程中能够通过调整较大音量使得自己实施更清楚的通话，同时由于第二声波与第一声波之间以及第三声波与第四声波之间发生抵消，从而能够使得在声音传输的过程中衰减较大，进而能够缓解用户在通话的过程中周围的人听到电子设备发出的声音的现象，达到防漏音的目的。
在较为优选的方案中，第二声波与第一声波的相位相反，第三声波与第四声波的相位相反，从而能够使得第二声波与第一声波相遇后以及第三声波与第四声波相遇后均能够产生反相抵消，进而能够进一步增大声音向远方传输过程中的衰减，有利于进一步减少电子设备的声音泄漏量。具体地，第二声波和第三声波相位可以相同，也可以不同。同理，第一声波与第四声波的 相位可以相同，也可以不同。
在具体的仿真检测过程中，通过仿真结果也能够得以验证，在第二出音孔120和第三出音孔170的发声方向上，声音能够得到较大的衰减。
如上文所述，第一出音孔110设置于设备主体100的第一侧，第二出音孔120和第三出音孔170设置于设备主体100的第二侧。一种可选的方案中，第一侧和第二侧，可以是设备主体100相背的两侧，也可以是设备主体100相邻的两侧，即第一侧与第二侧相邻设置。在第一侧和第二侧是设备主体100相背的两侧的情况下，第一出音孔110和第二出音孔120能够实现电子设备相背的两侧同时发声。在此种情况下，可以是：第一侧是电子设备安装显示屏100c的一侧，第二侧是电子设备上安装后盖100b的另一侧。当然，还可以是：第一侧是电子设备安装显示屏100c的一侧，第二侧是电子设备的侧方所在的一侧，例如可以是电子设备的中框的外侧。
在本发明实施例中，第一导音通道150和第二导音通道160起到声音传导及分别调节第二声波和第三声波的相位的作用。在具体的设计过程中，可以通过调节第一导音通道150和第二导音通道160的长度、横截面积等参数，达到分别调节第二声波和第三声波的相位的作用。
第一发声器件200和第二发声器件300的分布方式有多种。可选地，第一发声器件200的中心与第二发声器件300的中心之间的连线可以与电子设备的顶端边缘平行，从而能够使得第一发声器件200和第二发声器件300以较为规整的方式实施布设。
在较为优选的方案中，第一发声器件200和第二发声器件300可以对称地设置于第一对称轴线的两侧，且第二出音孔120和第三出音孔170可以对称设置于第一对称轴线的两侧。上述布设方式使得第一发声器件200与第二发声器件300以及第二出音孔120和第三出音孔170均以第一对称轴线对称设置，进而使得布局更加合理，有利于提高电子设备的外观性能，同时还有利于提高发声的均衡性。
同理，第一导音通道150和第二导音通道160也可以通过多种方式布设，一种具体的实施方式中，第一导音通道150和第二导音通道160可以对称地设置于第一对称轴线的两侧，此种布设方式使得通过第一导音通道150传输 至第二出音孔120的声音以及通过第二导音通道160传输至第三出音孔170的声音之间具有较好的同步性，进而有利于提高电子设备的声音性能。
为了更好地调节第二声波和第三声波的相位，第一导音通道150和第二导音通道160均可以为条形通道。第一导音通道150的第一端与第二子腔132连通，第一导音通道150的第二端与第二出音孔120连通。第二导音通道160的第三端与第四子腔连通，第二导音通道160的第四端与第三出音孔170连通。具体地，第一导音通道150的第一端与第一导音通道150的第二端可以在电子设备的长度方向依次设置，第二导音通道160的第三端与第二导音通道160的第四端也可以在电子设备的长度方向依次设置。
在本发明实施例中，第一导音通道150和第二导音通道160的形状及分布方式有多种。一种具体的实施方式中，如图1所示，第一导音通道150和第二导音通道160可以相平行。另一种具体的实施方式中，第一导音通道150和第二导音通道160可以相垂直，如图4所示。本文中，第二导音通道160也可以沿着电子设备的长度方向或电子设备的宽度方向延伸。当然，第一导音通道150和第二导音通道160还可以沿着其他方向延伸。
需要说明的是，本文中，电子设备的长度方向，指的是在电子设备的显示屏100c的平面内尺寸较大的方向，电子设备的宽度方向与电子设备的长度方向相垂直。在通常情况下，电子设备在垂直于显示屏100c的投影为长方形或类似于长方形的长形结构，电子设备的长度方向可以认为是投影的长边延伸的方向，电子设备的宽度方向可以认为是投影的宽边延伸的方向。本文所述的电子设备的顶端边缘，可以认为是电子设备上与所述的投影的一个宽边对应的边缘。
在另一种具体的实施方式中，请参考图3，第一导音通道150和第二导音通道160的轴线可以相同，第一导音通道150和第二导音通道160可以相向延伸。
在本发明实施例中，第一出音孔110、第二出音孔120、第一安装腔130、第二安装腔140、第一导音通道150、第二导音通道160和第三出音孔170的形成方式可以有多种。例如，第一出音孔110、第二出音孔120、第一安装腔130、第二安装腔140、第一导音通道150、第二导音通道160和第三出音孔 170均可以形成于设备主体100的设备壳体上。当然，第一出音孔110、第二出音孔120、第一安装腔130、第二安装腔140、第一导音通道150、第二导音通道160和第三出音孔170中至少部分可以由设备壳体与电子设备的其他功能器件(例如显示屏100c)共同形成。本发明实施例不限制第一出音孔110、第二出音孔120、第一安装腔130、第二安装腔140、第一导音通道150、第二导音通道160和第三出音孔170的具体形成方式。
在通常情况下，设备主体100可以包括设备壳体和显示屏100c，设备壳体可以包括中框100a、后盖100b和前盖。中框100a、后盖100b和前盖通常以可拆卸连接的方式固定相连，例如，中框100a与后盖100b以及前盖与中框100a之间均可以采用卡扣配合。
一种具体的实施方式中，显示屏100c可以设置于前盖，后盖100b连接于中框100a背离前盖的一侧，后盖100b开设有第二出音孔120和第三出音孔170，后盖100b与中框100a围成第一导音通道150和第二导音通道160。
在另一种可选的方案中，显示屏100c可以设置于后盖100b，后盖100b连接于中框100a背离前盖的一侧，前盖开设有第一出音孔110，后盖100b和中框100a围成第一导音通道150和第二导音通道160。
上文列举的两个具体实施方式中，显示屏100c可以设置于前盖，也可以设置于后盖100b，前盖和后盖100b分别连接于中框100a相背的两侧。第一导音通道150和第二导音通道160由后盖100b和中框100a围成，在后盖100b和中框100a装配完成后即可形成第一导音通道150和第二导音通道160，上述结构成型较为简单，同时又不会导致构件的结构过于复杂。
可选地，在显示屏100c设置于前盖的情况下，显示屏100c和前盖中的一者开设有第一出音孔110。为了避免对显示屏100c产生影响，在较为优选的方案中，显示屏100c的顶端与中框100a相对的部位围成第一出音孔110。还可以是：在显示屏100c设置于后盖100b的情况下，显示屏100c和后盖中的一者开设有第二出音孔120和第三出音孔170。本发明实施例不限制第一出音孔110、第二出音孔120和第三出音孔170的具体成型方式。
当然，第一安装腔130和第二安装腔140可以单独形成于设备壳体上，也可以由设备壳体与显示屏100c围成。请再次参考图2，显示屏100c可以与 中框100a和后盖100b围成第一安装腔130和第二安装腔140，上述围成第一安装腔130和第二安装腔140的方式有利于第一发声器件200和第二发声器件300的装配。
如上文所述，第一发声器件200安装于第一安装腔130，第二发声器件300安装于第二安装腔140。为了方便安装，在较为优选的方案中，在显示屏100c设置于前盖的情况下，中框100a可以包括第一限位部100a1，后盖100b可以包括第一支撑部100b1，第一发声器件200可以设置于第一限位部100a1和第一支撑部100b1之间。同理，在显示屏100c设置于前盖的情况下，中框100a可以包括第二限位部，后盖100b可以包括第二支撑部，第二发声器件300可以设置于第二限位部与第二支撑部之间。
在具体的装配过程中，第一发声器件200和第二发声器件300可以随着后盖100b与中框100a之间的组装而被分别固定在第一支撑部100b1与第一限位部100a1以及第二支撑部与第二限位部之间，从而实现夹紧固定。一种可选的方案中，第一支撑部100b1和第二支撑部均可以为支撑凸块，还可以为其他能够起到支撑的结构，例如支撑架。本发明实施例不限制第一支撑部100b1和第二支撑部的具体结构。
本发明实施例公开的电子设备还可以包括摄像模组，摄像模组设置于设备主体100的第二侧，也就是说，摄像模组与第二出音孔120和第三出音孔170均位于同一侧。摄像模组能够实现电子设备的摄像功能。
在较为优选的方案中，第一出音孔110和第二出音孔120均可以设置有防尘装饰网400，防尘装饰网400能够起到防尘的作用，与此同时，防尘装饰网400能够避免第一出音孔110和第二出音孔120以较大的孔径直接外露，进而能够起到一定的装饰作用。具体地，可以通过调节防尘装饰网400的目数、厚度、材质等参数，可以调节第二出音孔120的出音大小，达到更好的抵消作用。
在本发明实施例中，第二出音孔120可以为一个，也可以为至少两个。在第二出音孔120至少为两个的情况下，各第二出音孔120可以间隔设置。在较为优选的方案中，第二出音孔120可以等间距设置，即任意相邻的连个第二出音孔120之间距离均相等，从而能够使得多个不同位置的第二出音孔 120可以连续覆盖不同的声波频段，进而能够同时促进不同频段的声音的衰减，进而增强对漏音的抑制效果。
同理，第三出音孔170的数量可以为一个，也可以为至少两个。在第三出音孔170至少为两个的情况下，各第三出音孔170可以间隔设置。在较为优选的方案中，第三出音孔170可以等间距设置，即任意相邻的两个第三出音孔170之间的距离均相等，从而能够使得多个不同位置的第三出音孔170可以连续覆盖不同的声波频段，进而能够同时促进不同频段的声音的衰减，进而增强对漏音的抑制效果。
第二出音孔120为至少两个的情况下，能够拓宽第二声波的辐射宽度，从而实现与第一声波发生更好的抵消作用。同理，第三出音孔170为至少两个的情况下，能够扩宽第三声波的辐射宽度，从而能够实现与第一声波发生更好的抵消作用。
在第二出音孔120的数量为至少为两个的情况下，可选地，第一导音通道150可以为条形通道，第一导音通道150的第一端与第二子腔132连通，至少一个第二出音孔120与第一导音通道150的第二端连通。其他的第二出音孔120可以设置于第一导音通道150的第一端与第一导音通道150的第二端之间。上述布设方式更有利于提升声音性能。具体地，各第二出音孔120可以沿第一导音通道150的延伸方向依次排列，如图7所示。
同理，在第三出音孔170的数量为至少两个的情况下，可选地，第二导音通道160均可以为条形通道，具体地，第二导音通道160的第三端与第四子腔连通，至少一个第三出音孔170与第二导音通道160的第四端连通。其他的第三出音孔170可以设置于第二导音通道160的第三端与第二导音通道160的第四端之间。上述布设方式更有利于均衡发声，从而能够提升声音性能。具体地，各第三出音孔170可以沿第二导音通道160的延伸方向依次排列，如图7所示。
在较为优选的方案中，第一出音孔110可以为条形孔，如图1、图3、图4、图5、图6和图7所示，条形孔的延伸方向可以与电子设备的宽度方向相同。此种情况下，第一出音孔110具有较宽的发声范围，有利于提高电子设备的声音性能。
请参考图5和图6，一种可选的方案中，第一导音通道150可以包括第一主导音通道151和第一副导音通道152，第一主导音通道151的第五端连接于第二子腔132，第一主导音通道151的第六端可以向着远离第二子腔132的方向延伸，第一副导音通道152的第七端连接在第一主导音通道151的第五端与第一主导音通道151的第六端之间，且与第一主导音通道151连通，第一副导音通道152的第八端可以向着远离第一主导音通道151的方向延伸。
第一主导音通道151和第一副导音通道152中至少一者与至少一个第二出音孔120连通。例如图5所示，第一主导音通道151与一个第二出音孔120连通，第一副导音通道152与一个第二出音孔120连通。再例如图6所示，第一主导音通道151与两个第二出音孔120连通。上述结构中，由于第一导音通道150包括第一主导音通道151和第一副导音通道152，第一主导音通道151和第一副导音通道152形成的结构更加灵活，进而能够使得第一导音通道150具有更好的调节第二声波的相位的功能。
当然，第一主导音通道151和第一副导音通道152均与至少一个第二出音孔120连通，能够进一步扩宽第二声波的辐射宽度。
请再次参考图5和图6，一种可选的方案中，第二导音通道160可以包括第二主导音通道161和第二副导音通道162，第二主导音通道161的第九端连接于第四子腔，第二主导音通道161的第十端向着远离第四子腔的方向延伸，第二副导音通道162的第十一端连接在第二主导音通道161的第九端与第二主导音通道161的第十端之间，且与第二主导音通道161连通，第二副导音通道162的第十二端向着远离第二主导音通道161的方向延伸。
第二主导音通道161和第二副导音通道162中至少一者与至少一个第三出音孔170连通。例如图5所示，第二主导音通道161与一个第三出音孔170连通，第二副导音通道162与一个第三出音孔170连通。再例如图6所示，第二主导音通道161与两个第三出音孔170连通。上述结构中，由于第二导音通道160包括第二主导音通道161和第二副导音通道162，第二主导音通道161和第二副导音通道162形成的结构更加灵活，进而能够使得第二导音通道160具有更好的调节第三声波的相位的功能。
当然，第二主导音通道161和第二副导音通道162均与至少一个第三出 音孔170连通，能够进一步扩宽第三声波的辐射宽度。
如上文所述，在本发明实施例中，第一导音通道150能够调节第二声波的相位，从而使得第二声波与第一声波的相位不同，第二导音通道160能够调节第三声波的相位，从而使得第三声波与第四声波的相位不同。当然，设备主体100还可以开设有第三导音通道和第四导音通道，第一子腔131可以通过第三导音通道与第一出音孔110连通，第三导音通道能够调节第一声波的相位。在此种情况下，第一导音通道150和第三导音通道均能够使得第二声波与第一声波的相位不同，从而产生声波抵消。具体地，第一导音通道150和第三导音通道的结构不相同。
第三子腔通过第四导音通道与第一出音孔110连通，第四导音通道能够调节第四声波的相位。在此种情况下，第二导音通道160和第四导音通道均能够使得第三声波与第四声波的相同不同，从而产生声波抵消。具体地，第二导音通道160和第四导音通道的结构不相同。
