技术领域
本公开涉及电子产品技术领域,具体涉及一种电子设备。
背景技术
在用户使用电子设备进行手持通话的场景下,由于听筒靠近电子设备上方,且耳廓及人的面部不能将电子设备的听筒完全密封,因此,通话过程中,听筒所输出的声音会通过人体反射及绕射现象产生泄露。可见,相关技术中的电子设备在通话场景容易出现声音泄露的问题。
发明内容

所述显示模组开设有第一出音口,且所述显示模组和所述框体之间形成有第一导音通道,所述发声器件通过所述第一导音通道与所述第一出音口连通;
所述壳体和所述框体之间形成有第二导音通道,所述发声器件通过所述第二导音通道与第二出音口连通,所述第二出音口开设于所述框体,或者,所述第二出音口开设于所述壳体;
所述发声器件包括振膜,所述振膜朝向所述壳体设置,所述发声器件的内部具有导音间隙,所述第一导音通道通过所述导音间隙与所述振膜背对所述壳体的一侧连通。
本公开实施例中,由于振膜朝向壳体设置,如此,在发声器件工作过程中,振膜所产生的声波信号,一方面可以进入第二导音通道,另一方面可以通过发声器件内部的导音间隙进入第二导音通道,由于导音间隙在一定程度上可以减小进入第二导音通道中的声波信号的能量大小。因此,通过采用导音间隙连通所述振膜与第一导音通道,从而可以有效的平衡第一导音通道与第二导音通道中的声波能量,进而有利于使第一出音口发出的第一声波信号与第二出音口发出的第二声波信号形成声偶极子,如此,第一声波信号和第二声波 信号在远场可以相互抵消,从而防止电子设备出现声音泄露的问题。

上述第二出音口107可以是开设于所述框体102或壳体103的各种形状的开口,例如,可以是出音孔或出音缝等形式的开口。在本公开一个实施例中,所述第二出音口107可以是所述框体102与所述摄像头220的装饰件119的连接处的缝隙所形成的开口。下文以所述第二出音口107为开设于壳体103的开口为例,对本公开实施例提供的电子设备的结构作进一步的解释说明。此外,上述第一导音通道106和第二导音通道108可以是由所述电子设备内部的各种器件之间的间隙所形成的导音通道。例如,请参见图1至图2,在本公开一个实施例中,所述第一导音通道106由第一密封件114、第三防尘网112、装饰罩111、框体102、屏幕组件等器件之间的间隙共同形成。所述第二导音通道108由第二密封件115、第四防尘网116、用于支撑主板113的主板支架118、密封钢板117、壳体103和装饰件119等器件之间的间隙共同形成。
上述发声器件104可以是电子设备中常见的声学器件,可以理解的是,所述第一导音通道106可以形成所述发声器件104的前腔,即所述发声器件104的振膜1041朝向所述第一导音通道106。相应地,所述第二导音通道108可以形成所述发声器件104的后腔。在所述声学器件处于工作状态下,所述发声器件104发射的声波可以分别传播至第一导音通道106和第二导音通道108,并分别通过第一出音口105和第二出音口107传播至电子设备外。
具体地,由于第一出音口105和第二出音口107分别位于电子设备的前后两端,因此,所述第一出音口105和第二出音口107可以分别形成电子设备上的两个不同声源。请参见图7,在用户在手持电子设备通话场景下,由于第一出音口105通常贴合于用户的耳部,因此,从第一出音口105传播出的第一声波信号一部分进入人耳,另一部分会通过人体反射朝电子设备的背面一侧传播如图7箭头所指示的方向,所述第一声波信号的泄露部分可以与从所述第二出音口107传出的第二声波信号的相位相反,使得所述第一声波信号的泄露部分与所述第二声波信号形成声偶极子,以实现第一声波信号的泄露部分与所述第二声波信号相互抵消,从而防止用户通话过程中出现声音泄露的问题。此外,相对于仅开设第一出音口105而言,本公开实施例通过同时开设第一出音口105和第二出音口107,从而在电子设备的表面形成两个声源,因此,用户所能够听到的声音更为清楚,从而实现近场的声波信号加强的效果。
具体地,由于电子设备整机前部的第一出音口105是常规方案所具备的特征,所以开孔面积往往会比较充裕,相应的前部导音通道的尺寸也往往较为理想。而所述背部的第二出音口107并非常规开孔,往往需要做到比较隐蔽或足够小,而且具体的开孔位置也会受到限制,以避免出现对整机外观效果的影响。所以背部开口往往比较小、距离发声器件 104比较远,因此,所述第一导音通道106的通气性高于所述第二导音通道108的通气性。这样,将导致第一出音口105发出的声波能量中心的能量大小大于第二出音口107发出的反相声波的能量大小,限制了防漏音的效果。
基于此,请参见图1至图2,通过使所述发声器件104的振膜1041朝向所述壳体103,这样,在发声器件104工作过程中,振膜1041所产生的声波信号可以直接进入所述第二导音通道108,相应地,振膜1041所产生的声波信号需要经过发声器件104内部的导音间隙之后,才能进入所述第一导音通道106。即振膜1041所产生的声波信号需要依次通过导音间隙和所述第一导音通道106才能传播至第一出音口105,而振膜1041所产生的声波信号仅需通过第二导音通道108即可传播至第二出音口107。因此,由于导音间隙在一定程度上可以减小进入第二导音通道108中的声波信号的能量大小,从而有利于平衡第一导音通道106与第二导音通道108中的声波能量,进而有利于使第一出音口105发出的第一声波信号与第二出音口107发出的第二声波信号形成声偶极子。
其中,上述导音间隙可以是发声器件104内部的各种部件之间的间隙,例如,请参见图1,所述发声器件104包括磁性线圈221、磁性体222和音圈223,所述磁性体222位于所述磁性线圈221内部,且所述磁性体222与所述磁性线圈221的内壁之间形成环形间隙,所述音圈223的第一端与所述振膜1041连接,所述音圈223的第二端嵌设于所述环形间隙内,其中,所述磁性体222和所述磁性线圈221分别与所述音圈223间隔设置。如此,所述音圈223与所述磁性体222之间形成第一间隙,所述音圈223与所述磁性线圈221之间形成第二间隙,所述导音间隙可以包括所述第一间隙与所述第二间隙中的至少一者。
该实施方式中,由于振膜1041朝向壳体103设置,如此,在发声器件104工作过程中,振膜1041所产生的声波信号,一方面可以进入第二导音通道108,另一方面可以通过发声器件104内部的导音间隙进入第二导音通道108,由于导音间隙在一定程度上可以减小进入第二导音通道108中的声波信号的能量大小。因此,通过采用导音间隙连通所述振膜1041与第一导音通道106,从而可以有效的平衡第一导音通道106与第二导音通道108中的声波能量,进而有利于使第一出音口105发出的第一声波信号与第二出音口107发出的第二声波信号形成声偶极子,如此,第一声波信号和第二声波信号在远场可以相互抵消,从而防止电子设备出现声音泄露的问题。
可选地,所述第一导音通道106的声阻小于所述第二导音通道108的声阻,且所述第一导音通道106的声阻小于所述导音间隙的声阻。
其中,所述第一导音通道106的声阻小于所述第二导音通道108的声阻可以是指:所述第一导音通道106的通气性大于所述第二导音通道108的通气性。相应地,所述第一导音通道106的声阻小于所述导音间隙的声阻可以是指:所述第一导音通道106的通气性大于所述导音间隙的通气性。基于此,通过将所述振膜1041朝向所述壳体103设置,这样,在声波信号进入第一导音通道106之前,需要先经过导音间隙,相当于利用导音间隙间接 减小了第一导音通道106的通气性,从而有利于平衡发声器件104前腔与后腔之间的通气性,进而使得第一出音口105输出的第一声波信号的声波能量与第二出音口107输出的第二声波信号的声波能量相对平衡,如此,可以提高第一声波信号与第二声波信号在远场的抵消效果,从而进一步提高电子设备的防漏音效果。
可选地,所述第二出音口107内设有第一防尘网110。
该实施方式中,通过在所述第二出音口107内设有第一防尘网110,如此,有利于提高所述电子设备整体的防水、防尘性能。此外,也可以在所述第一出音口105处设置第二防尘网,以便于进一步提高所述电子设备整体的防水、防尘性能。且所述第二防尘网可以进一步增大所述第一导音通道106的声阻,从而有利于进一步平衡发声器件104前腔与后腔的通气性。
可选地,所述电子设备还包括装饰罩111,所述装饰罩111与所述框体102连接,且所述装饰罩111位于所述发声器件104与所述显示模组101之间,所述装饰罩111与所述第一出音口105相对,以减小所述第一出音口105的出音面积。
由上述实施例可知,由于电子设备的结构限制,从而导致第一出音口105发出的声波能量中心的能量大小大于第二出音口107发出的反相声波的能量大小,限制了防漏音的效果。
基于此,请参见图5和图6,本公开实施例中,通过所述装饰罩111与所述第一出音口105相对,以减小所述第一出音口105的出音面积。由于所述第一出音口105的出音面积减小,因此,可以有效的减小电子设备的第一出音口105发出的声波的能量中心的能量大小,从而有利于平衡第一出音口105与第二出音口107发出的声波的能量大小,进而提高防漏音效果。
可选地,所述第一出音口105包括条形缝,所述条形缝包括第一分段和第二分段,所述第一分段与所述第二出音口107之间的距离大于所述第二分段与所述第二出音口107之间的距离;
所述装饰罩111与所述第一分段相对,以遮挡所述条形缝的所述第一分段。
其中,由于装饰罩111遮挡所述条形缝的第一分段,而条形缝的第一分段为电子设备表面的开口,为避免装饰罩111影响电子设备的美观,因此,所述装饰罩111可以采用透明材质的装饰罩111,且所述装饰罩111可以粘贴于所述条形缝的内侧。
具体地,由于第一出音口105与第二出音口107之间的距离越接近时,二者所发出的声波信号的能量中心也越接近,因此,所形成的声偶极子的效果越好。基于此,本公开实施例中,通过遮挡条形缝的第一分段,从而将第一导音通道106中的声波信号引导至第二分段发出。这样,第一导音通道106中的声波信号的能量中心将向第二分段一侧偏移,从而减小第一声波信号的能量中心与第二声波信号的能量中心之间的距离,进而更有利于形成声偶极子。
可选地,所述第一分段与所述发声器件104相对设置,所述第二分段与所述发声器件 104的位置相对错开。
其中,所述第一分段与所述发声器件104之间的距离小于所述第二分段与所述发声器件104之间的距离。
请参见图6,在本公开实施例中,所述第一声波信号需要沿图6中箭头所指示的方向进行传播。即第一声波信号在传播至条形缝的第一分段时并无法向外传播,需要绕过第一分段才能从第二分段的开口处传播至外界,如此,有利于延长第一导音通道106的长度,进而进一步减小从第一出音口105发出的第一声波信号的能量大小,以进一步平衡第一出音口105与第二出音口107发出的声波的能量大小,进而提高防漏音效果。
可选地,所述发声器件104在所述显示模组101中的正投影与所述第一出音口105的位置相对错开。
该实施方式中,通过使所述发声器件104在所述显示模组101中的正投影与所述第一出音口105的位置相对错开,这样,有利于延长第一导音通道106的长度,以进一步平衡第一出音口105与第二出音口107发出的声波的能量大小,进而提高防漏音效果。
可选地,所述电子设备包括拍摄模组,所述壳体103上开设有安装孔,所述拍摄模组穿设于所述安装孔内,所述壳体103与所述拍摄模组之间的间隙形成所述第二出音口107。
该实施方式中,通过使所述壳体103与所述拍摄模组之间的间隙形成所述第二出音口107,如此,由于所述拍摄模组的遮挡,可以使得所述第二出音口107更为隐蔽,有利于提高电子设备整体的美观性。
可选地,所述电子设备还包括主板支架118和密封板,所述主板支架118与所述密封板相对设置,所述主板支架118与所述框体102连接,所述密封板与所述壳体103连接,且所述第二导音通道108形成于所述主板支架118与所述密封板之间。
该实施方式中,所述主板支架118与所述密封板可以分别形成所述第二导音通道108两个相对的内侧壁,如此,可以通过所述主板支架118和密封板将所述第二导音通道108与电子设备中的其他器件进一步隔开,从而有利于进一步提高电子设备整体的防水、防尘性能。
