下面结合附图和实施例，对本发明作进一步的详细描述。特别指出的是，以下实施例仅用于说明本发明，但不对本发明的范围进行限定。同样的，以下实施例仅为本发明的部分实施例而非全部实施例，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它实施例，都属于本发明保护的范围。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
作为在此使用的“电子设备”(或简称为“终端”)包括，但不限于被设置成经由有线线路连接(如经由公共交换电话网络(PSTN)、数字用户线路(DSL)、数字电缆、直接电缆连接，以及/或另一数据连接/网络)和/或经由(例如，针对蜂窝网络、无线局域网(WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器，以及/或另一通信终端的)无线接口接收/发送通信信号的装置。被设置成通过无线接口通信的通信终端可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括，但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。手机即为配置有蜂窝通信模块的电子设备。
请一并参阅图1至图3，图1是本申请电子设备一实施例的整体结构示意图，图2是图1实施例中电子设备另一视角的结构示意图，图3是图1实施例中电子设备的部分结构拆分示意图。需要说明的是，本申请中的电子设备可以包括手机、平板电脑、笔记本电脑、可穿戴设备等具有扬声器的电子设备。其中，本实施例的图示中仅以手机为例进行说明。该电子设备10包括壳体100以及扬声器200。当然，电子设备还可以包括显示屏、电池、电路板、摄像头等结构，在本领域技术人员的理解范围内，本申请实施例中就不再详述。需要说明的是，本申请实施例中的术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或组件。
具体而言，请一并参阅图4，图4是图1实施例中电子设备在A-A处的结构剖视示意图，可选地，本实施例中的扬声器200为双振膜扬声器，该扬声器200的相背两侧分别设有第一振膜201以及第二振膜202，所述第一振膜201和所述第二振膜202可被驱动发出振动幅度相同且相位相反的声音，进而形成偶极声源。偶极声源是指两个相距很近的声源点S+和S-，它们的振动幅值相同，但是相位相反，由这样的两个点声源构成的合成声源。
请继续参阅图4，本实施例中壳体100的内部设有分别与所述第一振膜201以及所述第二振膜202连通的第一出声通道1100和第二出声通道1200，所述壳体100的表面设有分别与所述第一出声通道1100以及所述第二出声通道1200连通的第一出声孔101以及第二出声孔102。
可选地，请继续参阅图1和图2，本实施例中的壳体100包括第一表面110、第二表面120以及侧面130；所述第一表面110和所述第二表面120相背设置，所述侧面130分别与所述第一表面110以及所述第二表面120连接。其中，侧面130可以是环周面结构。第一表面110上可以设置电子设备的显示屏，而第二表面120则可以是电子设备的后壳。本申请实施例仅以简图为例示意性说明，不限制电子设备其他器件的设计。需要说明的是，本申请实施例中的术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”、“第三”的特征可以明示或者隐含地包括至少一个该特征。本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
请继续参阅图4，本实施例中的第一出声孔101的朝向X1与垂直于所述第一表面110的方向(图4中箭头Z1向)之间的夹角a1小于45度，其中，第一出声孔101可以是设置于第一表面110上或者是第一表面110跟侧面130(顶部侧面)的夹角处(图4中所示)。第一出声孔101的出声主要是服务于通话等需要进行小声等私密性要求高的应用场景。
可选地，本实施例中的第二出声孔102则设于所述侧面(一般为顶部侧面)130，第二出声孔102的朝向不做具体限定。第二出声孔102的出声主要有两种应用场景。在私密性场景中，第二出声孔102的出声与第一出声孔101的出声配合产生振动幅度相同，相位相反的声音，形成偶极声源，以使得在电子设备远场处产生反相位声场叠加，降低声音响度和清晰度，从而使电子设备远场处的其他人无法听清通话声音，实现通话的私密性。在外部功放的应用场景中，第二出声孔102的出声与第一出声孔101的出声产生相位相同的声音，形成同相位声场叠加，增强声音响度，实现电子设备外放效果的提升。
请继续参阅图4，为了实现更好的私密性效果，形成可靠有效的偶极声源。可选地，所述第一出声通道1100的体积是所述第二出声通道1200的体积的0.5-2倍。具体可以是第一出声通道1100的体积是所述第二出声通道1200的体积的0.5倍、0.6倍、0.8倍、1倍(相同)、1.5倍以及2倍等，而所述第一出声通道1100的长度可以是所述第二出声通道1200的长度的0.5-2倍。具体可以是第一出声通道1100的长度是所述第二出声通道1200的体积的0.5倍、0.6倍、0.8倍、1倍(相同)、1.5倍以及2倍等。可选地，在一实施例中，具体可以是设计为所述第一出声通道1100和所述第二出声通道1200的体积以及长度均相同。
可选地，所述第一出声孔101的面积是所述第二出声孔102的面积的0.5-2倍，具体可以是第一出声孔101的面积是所述第二出声孔102的面积的0.5倍、0.6倍、0.8倍、1倍(相同)、1.5倍以及2倍等。在一些实施例中可以设计为第一出声孔101的面积和所述第二出声孔102的面积相同。需要说明的是，本申请实施例中所有方向性指示(诸如上、下、左、右、前、后……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
可选地，请继续参阅图4，本实施例中的第一振膜201的面积是第二振膜202的面积的0.5-2倍，具体可以是第一振膜201的面积是第二振膜202的面积的0.5倍、0.6倍、0.8倍、1倍(相同)、1.5倍以及2倍等。在一些实施例中，可以是设计第一振膜201的面积和第二振膜202的面积相同。
可选地，为了使得扬声器200的振膜产生更好的偶极声源效果，可以设计所述第一出声孔101和所述第二出声孔102的中心距离d不大于30mm。在30mm内产生的声音振幅差异小于10％，第一出声孔101和所述第二出声孔102的中心距离d越大，产生的偶极声源效果越差，进而私密性越差。其中，第一出声孔101和所述第二出声孔102的中心距离d的具体数值可以是30mm、28mm、25mm、20mm、15mm以及10mm等数值，此处不做具体限定。
请一并参阅图5，图5是图1实施例中电子设备的局部结构示意图，本实施例中所述的出声孔的中心指的是出声孔的几何中心，并不限于出声孔的具体形状以及数量，譬如，本实施例中的第一出声孔101为条状结构，其中心应该是图中标注101a的位置，而第二出声孔102可以是由多个小孔组成，那么，其中心应该是多个小孔组成的几何中心，也即图中标注102a的位置。即，101a和102a之间的距离为第一出声孔101和所述第二出声孔102的中心距离d(结合参阅图4和图5)。
本申请实施例中的第一出声孔101以及第二出声孔102的形状并不限于图示中所示，还可以是其他结构，譬如由多个小孔矩阵排列形成的出声孔或者是单一的圆孔等，第一出声孔101以及第二出声孔102的具体形状还可以是根据电子设备整体造型ID进行综合考量设计。
本申请实施例提供的电子设备，可以控制双振膜扬声器通过两条独立的出声通道发出振动幅度相同且相位相反的声音，进而形成偶极声源，在电子设备的远场处产生反相位声场叠加，降低声音响度和清晰度，从而使电子设备远场处的其他人无法听清通话声音，实现通话的私密性。在外部功放的应用场景中，两个出声孔发出相位相同的声音，形成同相位声场叠加，增强声音响度，实现电子设备外放效果的提升。
请参阅图6，图6是本申请电子设备另一实施例的局部结构剖视示意图，本实施例中的电子设备10同样可以是包括壳体100以及扬声器200。扬声器200同样为双振膜扬声器，扬声器200的相背两侧分别设有第一振膜201以及第二振膜202，所述第一振膜201和所述第二振膜202可被驱动发出振动幅度相同且相位相反的声音，进而形成偶极声源。
其中，壳体100的内部同样是设有分别与所述第一振膜201以及所述第二振膜202连 通的第一出声通道1100和第二出声通道1200，所述壳体100的表面设有分别与所述第一出声通道1100以及所述第二出声通道1200连通的第一出声孔101以及第二出声孔102。壳体100包括第一表面110、第二表面120以及侧面130；所述第一表面110和所述第二表面120相背设置，所述侧面130分别与所述第一表面110以及所述第二表面120连接。

与前述实施例不同的是，本实施例中的第二出声孔102的朝向X2与垂直于所述第二表面120的方向(图6中箭头Z2向)之间的夹角a2小于45度。其中，第二出声孔102可以是设置于第二表面120上或者是第二表面120跟侧面130(顶部侧面)的夹角处(图6中所示)。其中，第二出声孔102的出声主要有两种应用场景。在私密性场景中，第二出声孔102的出声与第一出声孔101的出声配合产生振动幅度相同，相位相反的声音，形成偶极声源，以使得在电子设备远场处产生反相位声场叠加，降低声音响度和清晰度，从而使电子设备远场处的其他人无法听清通话声音，实现通话的私密性。在外部功放的应用场景中，第二出声孔102的出声与第一出声孔101的出声产生相位相同的声音，形成同相位声场叠加，增强声音响度，实现电子设备外放效果的提升。
