技术领域
本申请属于通信设备技术领域,具体涉及一种电声模组和电子设备。
背景技术
随着技术的进步以及用户需求的提升,在电子设备的使用过程中,为了在较为嘈杂的环境中能够进行较为清楚的通话,用户往往需要将音量调大。在此种情况下,由于用户的耳朵与电子设备之间不可避免地存在缝隙,导致声音自缝隙传出至外界,使得周围的人也会听到用户的通话内容,对应地,为了避免隐私泄露,用户往往不得已将音量调小,这又导致用户自身较难清楚地进行通话,造成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。
发明内容
本申请公开一种电声模组和电子设备,以解决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
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、完整的描述,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在没有作出创造性劳动前提下所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声模组和电子设备进行详细地说明。
如图1至图9所示,本申请实施例公开一种电声模组和电子设备,电声模组包括安装件120、第一发声器件310和第二发声器件320。
其中,安装件120开设有第一安装腔、第二安装腔、第一出音孔125、第二出音孔126和导音通道127。具体地,第一安装腔、第二安装腔、第一出音孔125、第二出音孔126和导音通道127中的至少一者可以在安装件120的成型过程中一并形成,或者,可以在安装件120成型之后,经钻加工等方式形成。第一安装腔、第二安装腔、第一出音孔125、第二出音孔126和导音通道127的具体形状和尺寸等参数,可以根据第一发声器件310和第二发声器件320的实际尺寸等参数对应确定,此处不作限定。
在布设第一安装腔、第二安装腔、第一出音孔125、第二出音孔126和导音通道127的过程中,如图2所示,第一出音孔125设置在安装件120的第一侧,且在电声模组应用至电子设备中的情况下,可以使安装件120的第 一侧朝向电子设备的显示侧,电子设备的显示侧即为电子设备中显示屏140所在的一侧,进而使用户在利用包括前述电声模组的电子设备听取声音信息时,通过使电子设备的显示侧朝向用户的耳部,且使第一出音孔125与用户耳部对准,最大化地保证电声模组产生的声音信号均能够自第一出音孔125传入用户的耳部。具体地,第二出音孔126可以设置在安装件120的前述第一侧,当然,第二出音孔126亦可以设置在安装件120的其他侧面,此处不作限定。第二出音孔126与第一出音孔125各自的面积等参数均可根据所对应的第一发声器件310和第二发声器件320的尺寸确定。
并且,第一发声器件310安装至第一安装腔内,且第一发声器件310将第一安装腔分隔为第一前腔121和第一后腔122,第二发声器件320安装至第二安装腔内,且将第二安装腔分隔为第二前腔123和第二后腔124。如上所述,第一安装腔和第二安装腔的尺寸和形状,均可以根据第一发声器件310和第二发声器件320的具体结构对应确定,以保证第一发声器件310具备隔绝第一前腔121和第一后腔122的能力,且保证第二发声器件320具备隔绝第二前腔123和第二后腔124的能力。第一发声器件310发出的声波能够分别传入第一前腔121和第一后腔122之内,对应地,第二发声器件320发出的声波能够分别传入第二前腔123和第二后腔124之内,通过使第二后腔124为密闭腔,基本可以防止第二发声器件320发出的声波经第二后腔124传出至电声模组之外。
同时,如图6-图8所示,第一前腔121与第一出音孔125连通,第一后腔122通过导音通道127与第二前腔123连通,第二前腔123与第二出音孔126连通。在第一发声器件310工作的情况下,第一前腔121内的声波能够自第一出音孔125传出,以向用户的耳部传入,第一后腔122内的声波能够传播至第二前腔123内,且自第二出音孔126传出,相应地,自第二出音孔126传出的声波能够传出至电声模组之外。继而,利用第一发声器件310通过第二出音孔126发出的第二声波与第一发声器件310通过第一出音孔125 发出的第一声波的相位相异的特点,使相位不同的第一声波和第二声波在相遇后产生抵消作用,增强声波在向电声模组之外传播过程中的衰减效率和程度,防止出现通话声音泄露的情况。
本申请实施例提供一种电声模组和电子设备,其包括安装件120、第一发声器件310和第二发声器件320,第一发声器件310安装在安装件120的第一安装腔内,且将第一安装腔分隔为第一前腔121和第一后腔122,第二发声器件安装在安装件120的第二安装腔内,且将第二安装腔分隔为第二前腔123和第二后腔124,第一前腔121与安装件120的第一出音孔125连通,第一后腔122通过导音通道127与第二前腔123连通,且第二前腔123与第二出音孔126连通,从而使第一发声器件310发出的第一声波能够自第一前腔121经第一出音孔125传出,第一发声器件310发出的第二声波能够自第一后腔122经导音通道127和第二前腔123,且最终从第二出音孔126传出。
在包括上述电声模组的电子设备处于手持通话或听取声音信息时,第一出音孔125和第二出音孔126各自发出的第一声波和第二声波均可以向电子设备之外传播声音信号;并且,利用第一发声器件310经第一出音孔125传出的第一声波与经第二出音孔126传出的第二声波的相位相异的特性,保证第一声波和第二声波在电子设备周围相遇时能够产生相互抵消的效果,从而在第一发声器件310的音量控制得相对较大的情况下,在保证用户能够清楚地进行通话或听取声音的同时,也基本可以防止电子设备传出的声音信息被周围的其他人听到,进而保护用户的隐私,使电子设备兼顾安全性及清楚通话的能力。
在具体的仿真检测过程中,如图9所示,通过仿真结果也能够得以验证,在采用上述技术方案的情况下,通过使第一发声器件310的第一声波和第二声波分别自第一出音孔125和第二出音孔126传出,在200Hz~3000Hz的频段,可以使漏音的音量大小降低5~20dB不等。
另外,在上述实施例提供的电声模组中,第一发声器件310具体可以为 受话器,第二发声器件320具体可以为扬声器,在用户使用包括上述电声模组的电子设备的过程中,受话器可以为用户提供通话或听取语音信息等作用,而在用户需要观看视频或听音乐等活动时,则可以利用扬声器进行声音外放,且使第二发声器件320传出的声音自第二前腔123经第二出音孔126传出,由于第二后腔124为密封腔,从而使得第二发声器件320发出的声音仅会自第二出音孔126传出,第一后腔122和第二后腔124均不会对第二发声器件320的发声效果产生影响,提升用户的视听感受。
更直观地说,第一发声器件310和第二发声器件320均为电子设备中的基本配置器件,本申请实施例利用电子设备的电声模组中的已有部件,通过对电声模组的安装件120进行改进,在基本无需额外增加器件的情况下,实现解决电子设备通话漏音的目的,改进成本相对较低,改进效果相对较好。
进一步地,可以对第一出音孔125和第二出音孔126的位置等参数进行设定,使自第一出音孔125传出的第一声波与自第二出音孔126传出的第二声波在电声模组周围相遇时,第一声波和第二声波的相位相反,以进一步提升第一声波和第二声波的抵消作用效果,从而保证在利用电声模组的第一出音孔125传播声音信息时,电声模组基本不存在向周围漏音的情况,最大化地防止用户的隐私被泄露。
可选地,第一出音孔125为第一安装腔的腔口,且第一出音孔125为第一安装腔的脱模口,对应地,第二出音孔126为第二安装腔的腔口,且第二出音孔126为第二安装腔的脱模口。在采用上述技术方案的情况下,利用分模注塑的方式,使得第一安装腔、第二安装腔、第一出音孔125和第二出音孔126可以经一体成型的方式随安装件120一并形成,从而提升安装件120的加工效率,进而提升整个电声模组的生产效率,还可以提升第一安装腔和第二安装腔的加工精度,进而保证不同批次的电声模组的漏音问题的改善程度均相对较好。另外,在上述技术方案中,导音通道127可以在安装件120加工完成之后,利用钻加工等方式形成,使第一后腔122能够通过导音通道 127与第二前腔123连通。
在上述技术方案中,安装件120成型之后,第一发声器件310可以经第一出音孔125安装至第一安装腔内,第二发声器件320可以经第二出音孔126安装至第二安装腔内,且可以利用密封垫等部件保证第一发声器件310能够将第一安装腔分隔为第一前腔121和第一后腔122,且使第一发声器件310可以通过粘接或卡接等方式固定在第一安装腔的中部。对应地,亦可以利用粘接等固定方式,且辅以密封垫的密封方式,将第二发声器件320安装在第二安装腔内,且使第二发声器件将第二安装腔分隔为第二前腔123和第二后腔124。
在本申请的另一实施例中,沿第一出音孔125的轴向,如图6所示,第一发声器件310贴合于第一安装腔中靠近第一出音孔125的内壁,在这种情况下,第一发声器件310发出的声波可以直接经第一前腔121和第一出音孔125传出至安装件120之外,且自第一出音孔125传出至电声模组之外,最大化地减小第一发声器件310自第一出音孔125传出的声波的传播路径的长度,使第一声波的有效传播程度更高。并且,在采用上述技术方案的情况下,如图6所示,由于第一前腔121为安装件120中第一安装腔的腔壁围成,且第一前腔121整体朝向第一发声器件310,从而使得第一声波基本不会在第一前腔121内发生反射,这可以进一步提升第一发声器件310所发出的第一声波的有效性,进一步提升用户的通话体验。
为了降低第一安装腔、第二安装腔、第一出音孔125和第二出音孔126的形成难度,如图4-图6所示,安装件120可以包括安装基体120a和封装部120b,安装基体120a设有第一出音孔125和第二出音孔126,且安装基体120a与封装部120b围成第一安装腔和第二安装腔。在采用前述技术方案的过程中,安装基体120a可以采用分模注塑等方式一体形成,且在第一出音孔125的轴向上,保证第一出音孔125的投影位于第一安装腔的投影之内,第一安装腔的投影的边缘位于第一出音孔125的投影之外,进而使第一安装腔靠近第一 出音孔125的一侧的内壁形成有用以限制第一发声器件310位置的结构。相似地,第二安装腔和第二出音孔126亦是如此,以保证第二安装腔靠近第二出音孔126的一侧内壁形成有用以限制第二发声器件320位置的结构。
对应地,封装部120b具体可以为板状结构件,第一安装腔和第二安装腔沿垂直于封装部120b的轴向的方向分布,封装部120b与第一出音孔125的轴向垂直,以保证安装基体120a能够采用上述分模注塑的方式形成,用于成型的模具至少包括两个,一者可以沿第一出音孔125的轴向向封装部120b所在的一侧取出,另一者可以沿第二出音孔126的轴向向背离第二安装腔的一侧取出。
更具体地,可以使第一出音孔125的尺寸和形状与第一发声器件310中发声区域的尺寸和形状对应相同,继而使第一发声器件310的发声区域与第一出音孔125对应设置,保证第一发声器件310的发声有效性较高。
在上述实施例提供的电声模组中,导音通道127可以设置在第一安装腔和第二安装腔的同一侧,在本申请的另一实施例中,如图8所示,沿第一安装腔和第二安装腔的分布方向,导音通道127位于第一安装腔和第二安装腔之间,这基本可以使导音通道127的长度达到最短,降低第二声波的消耗量。并且,在采用上述技术方案的情况下,可以尽量减少导音通道127的弯折次数,降低声波的消耗量和相位控制难度,提升电声模组的漏音改善幅度。
其中,导音通道127设有第一连通孔和第二连通孔,第一连通孔与第一后腔122连通,第二连通孔与第二前腔123连通。可选地,第一连通孔和第二连通孔的轴向平行,且二者的轴向均与第一后腔和第二前腔的分布方向平行,在这种情况下,导音通道127为一直线状结构。
在本申请的另一实施例中,如图2和图8所示,第一出音孔125设置在安装件120的第一侧,第二出音孔126设置在安装件120的第二侧,第一侧和第二侧分别为安装件120上相邻的两个侧面。在本实施例中,一方面可以使第二声波的有效性相对较高,减少第二声波的损耗量,另一方面还可以防 止第一声波和第二声波之间相对干扰,保证用户的收音效果相对较高。
基于上述实施例,可选地,第一连通孔的轴向平行于第一出音孔125的轴向,第一出音孔125的轴向和第二出音孔126的轴向均垂直于第二连通孔的轴向。在本实施例中,在连通第一后腔122和第二前腔123时,通过为导音通道127设置一弯折处,可以使整个安装件120在第一出音孔125的轴向上的尺寸相对较小;并且,通过使第一连通孔和第二连通孔相互垂直,可以改善安装件120中导音通道127所在处的结构强度,提升安装件120的结构稳定性。
本申请实施例公开的电声模组中,导音通道127可以在安装件120的形成之后再通过钻加工等方式形成。在本申请的另一实施例中,可选地,如图5和图8所示,安装件120包括分体设置的安装基体120a和盖板120c,安装基体120a和盖板120c密封连接,且围成导音通道127。在这种情况下,导音通道127的凹陷部分可以随安装基体120a经一体注塑的方式一并形成,这可以降低导音通道127的加工难度,且可以保证不同安装件120上的导音通道127的结构和尺寸的对应一致性,保证每一安装件120的导音效果均基本相同。如上所述,安装基体120a上还可以形成有第一出音孔125和第二出音孔126,基于上述实施例,安装件120可以包括安装基体120a、盖板120c和上述封装部120b,封装部120b和盖板120c分别密封连接在安装基体120a的相背两侧。
可选地,如图8所示,本申请实施例提供的电声模组还可以包括防尘网130,第一连通孔处设有防尘网130,在采用这种技术方案的情况下,第二声波自第一后腔122经导音通道127传播向第二前腔123的过程中,可以利用防尘网130将第一后腔122内的灰尘或杂质阻挡在导音通道127之外,防止灰尘等杂质对导音通道127的导音效果产生不利影响,甚至堵塞导音通道127。防尘网130具体可以采用不锈钢等金属材质制成,以提升防尘网130的结构强度和使用寿命,防尘网130具体可以通过粘接的方式固定在第一连通孔之 外。
基于上述任一实施例公开的电声模组,本申请实施例还提供一种电子设备,电子设备包括壳体和上述任一电声模组。其中,壳体设有容纳腔、第三出音孔111和第四出音孔112,第三出音孔111设置在容纳腔的第一侧,第四出音孔112设置在容纳腔的第二侧,第一侧和第二侧为容纳腔中相邻的两个侧面。安装件120安装于容纳腔,且使第一前腔121能够通过第一出音孔125与第三出音孔111连通,第二前腔123能够通过第二出音孔126与第四出音孔112连通,进而使第一声波能够经第三出音孔111传出,且使第二声波能够自第四出音孔112传出。可选地,电子设备还可以设置有第五出音孔113,第五出音孔113处亦可以对应设置有扬声器等发声器件,第五出音孔113与第四出音孔112分别设置在壳体110中相背的两端,使电子设备具备立体声音效的能力。
进一步地,电子设备还可以包括显示屏140和后壳150等部件,整体上来说,壳体110可以为立方体状结构件,显示屏140安装在壳体110上,显示屏140所在一侧即为电子设备的显示侧,显示屏140可以展示电子设备所需显示的内容,后壳150设置在壳体110中背离显示屏140所在的另一侧,后壳150所在一侧为电子设备的背面。
基于此,第三出音孔111可以整体位于壳体110上或整体位于显示屏140上,或者,第三出音孔111可以设置在壳体110和显示屏140之间,也即,壳体110和显示屏140围成第一出音孔125。第四出音孔112设置在壳体110中相邻于显示侧的另一侧,也即,第四出音孔112设置在第三出音孔111的相邻侧,如上所述,壳体110整体为立方体状结构,以显示侧为电子设备的正面为例,背离显示侧的一侧,即后壳150所在的一侧为电子设备的背面,位于正面和背面之间的环形侧面即为相邻于显示侧的一侧,第四出音孔112设置在壳体110的环形侧面上。在这种情况下,由于第三出音孔111设置在壳体110的显示侧,第四出音孔112设置在壳体110中相邻于显示侧的另一 侧,使得第三出音孔111和第四出音孔112均具备向电子设备周围扩散声波的能力,进而保证第一声波和第二声波具备相遇且互相抵消的条件。
为了最大化地提升电子设备的显示面积,可选地,第三出音孔111位于显示侧靠近壳体110的第一端的边缘,也即,第三出音孔111位于显示侧的边缘处,这可以尽量降低第三出音孔111的存在对电子设备显示面积的影响。举例来说,第三出音孔111可以设置在壳体110中显示侧靠近顶部的边缘位置,顶部即为电子设备处于手持通话状态下,电子设备中壳体110位于最上方的一端。
基于上述情况,第四出音孔112设置在电子设备的第一端的端面,在这种情况下,自第三出音孔111泄露出的声波中的大部分的传播范围均为第一端背离电子设备的一侧空间,基于此,通过使第四出音孔112设置在第一端的端面,可以使第四出音孔112朝向第三出音孔111的主要漏音区域,进而最大化地使第二声波与泄露的第一声波相互叠加抵消,改善电子设备的漏音情况。
可选地,如图6所示,沿第三出音孔111的轴向,第三出音孔111的投影位于第一出音孔125的投影之外,在这种情况下,可以尽量防止电子设备之外的灰尘等杂质经第三出音孔111进入第一出音孔125,从而对第一发声器件310的发声效果产生不利影响。进一步地,可以在第三出音孔111处设置防尘网,以利用防尘网隔绝灰尘等杂质,防止杂质经第三出音孔111进入电子设备之内。
