为解决水汽容易从电子设备壳体与扬声器之间的缝隙进入电子设备壳体的内部的技术问题,本申请实施例提供一种电声组件,以解决上述技术问题。该电声组件可以应用于电子设备,该电子设备可以是平板电脑、手机、电子阅读器、智能手表、个人计算机(Personal Computer,PC)、笔记本电脑、车载设备、网络电视、可穿戴设备等具有网络功能 的智能设备。本申请实施例的电子设备以智能手表为例。
请参阅图1和图2,图1是本申请第一实施例中电声组件10的结构示意图,图2是图1实施例中电声组件10的结构拆分示意图,电声组件10包括壳体11、电声器件12、音腔支架13以及固定支架14。其中,电声器件12是可以将音频电信号转换成声音信号的电子器件,例如扬声器、受话器、喇叭等。
可选的,壳体11可以由前壳、中框以及后壳组成;或者,壳体11可以由前壳和中框组成;又或者,壳体11可以由后壳和中框组成;再或者,壳体11可以由中框组成。应理解,本申请实施例对壳体11的具体结构划分不作限定。
具体而言,壳体11开设有支架孔111,音腔支架13至少部分设于支架孔111内并与壳体11配合密封防水,以避免水汽进入壳体11内部。音腔支架13上开设有出音槽131,该出音槽131与支架孔111连通,以在电声器件12发声时将声音发出。音腔支架13上还设有放置槽132,放置槽132的底壁与出音槽131连通,其中,放置槽132用于放置电声器件12,并对电声器件12进行固定。
优选的,电声器件12与音腔支架13的放置槽132粘接连接,例如,可以通过点胶的方式将电声器件12固定于音腔支架13的放置槽132。电声器件12的出音面正对出音槽131,通过点胶的方式使得电声器件12的出音面与音腔支架13的放置槽132形成防水界面,避免水汽进入电声器件12的出音面与放置槽132之间的缝隙,从而进入壳体11内部。
固定支架14设于电声器件12背离音腔支架13的一侧,并与壳体11的内侧壁固定连接,以进一步夹持固定电声器件12以及音腔支架13。例如,可以通过螺丝或者螺栓连接的方式将固定支架14与壳体11固定连接,同时通过固定支架14与壳体11配合夹持固定电声器件12以及音腔支架13。当然,在其他实施方式中,可以在固定支架14、音腔支架13以及壳体11的相应位置分别开设螺孔,并进一步通过螺丝或者螺栓将固定支架14、音腔支架13以及壳体11固定连接。其中,固定支架14与壳体11配合夹持固定音腔支架13,固定支架14与音腔支架13配 合夹持固定电声器件12。
可以理解的,电声器件12本身具有较高的防水级别,不易被外部水汽进入损坏,但水汽容易进入壳体11内部而损坏壳体11内部的电路结构,如电路板与电声器件12之间的电路连接结构。本申请实施例首先在电声器件12的出音面与音腔支架13之间通过点胶连接形成防水界面,避免水汽通过电声器件12的出音面与音腔支架13之间的缝隙进入壳体11内部。
结合参阅图3,图3是图1实施例中电声组件10沿A-A向的部分截面结构示意图,音腔支架13容纳于支架孔111的端部套设有防水圈133,音腔支架13与壳体11配合挤压防水圈133以形成防水界面,可以避免水汽通过音腔支架13与壳体之间的缝隙进入壳体11内部。防水圈133可以采用诸如橡胶圈、硅胶圈等弹性圈,以在音腔支架13与壳体11配合挤压下产生形变,进而起到防水效果。
具体而言,防水圈133套设于音腔支架13靠近壳体11的端部,并在音腔支架13与壳体配合时,防水圈133抵顶于支架孔111的内侧壁,从而在音腔支架13的端部外侧与支架孔111内侧壁之间形成防水界面。换言之,防水圈133套设于出音槽131的外周,即防水圈133设于音腔支架13的端部外侧并环绕于出音槽131,以在音腔支架13与壳体配合时防水圈133抵顶于支架孔111的内侧壁,并产生形变以实现防水效果。
本申请实施例提供的电声组件,通过在电声器件的出音面与音腔支架之间的缝隙设置防水界面,以及在音腔支架与壳体之间的缝隙设置防水界面,多重防水保护,避免水汽进入壳体内部而损坏壳体内部的电路结构。
申请人研究发现,上述第一实施例实现防水效果需要借助于音腔支架,在能实现较好的防水效果的同时可能会提升电声器件的成本。因此,申请人进一步研究发现,如果不借助音腔支架也能实现较好的防水效果,势必会对提升产品的竞争力有较大的提升。
基于此,本申请第二实施例还提供了一种电声组件,以取消第一实施例中的音腔支架,同时本申请第二实施例提供的电声组件能够实现较 好的防水效果。
请参阅图4和图5,图4是本申请第二实施例中电声组件20的结构示意图,图5是图4实施例中电声组件20的结构拆分示意图,电声组件20包括壳体21、电声器件22、防水件23以及固定件24。其中,电声器件22是可以将音频电信号转换成声音信号的电子器件,例如扬声器、受话器、喇叭等。
可选的,壳体21可以由前壳、中框以及后壳组成;或者,壳体21可以由前壳和中框组成;又或者,壳体21可以由后壳和中框组成;再或者,壳体21可以由中框组成。应理解,本申请实施例对壳体21的具体结构划分不作限定。
在本申请实施例中,以壳体21由中框组成为例进行说明。壳体21开设有出音孔211,该出音孔211贯穿壳体21即中框的内外表面。电声器件22位于壳体21内部,且电声器件22的出音面正对出音孔211设置,以在电声器件22发声时能够通过出音孔211将声音传播到壳体21的外部。防水件23设于壳体21的内侧壁,且环绕于出音孔211。电声器件22设于防水件23背离壳体21的内侧壁的一侧,固定件24与壳体21配合夹持固定电声器件22,以使得电声器件22挤压防水件23产生形变,进而密封壳体21的内侧壁与电声器件22之间的间隙。
具体而言,固定件24与壳体21相互固定连接,并与壳体21配合夹持固定电声器件22。电声器件22被夹持在壳体21的内侧壁(即壳体21开设有出音孔211的内侧壁)和固定件24之间。换言之,壳体21开设有出音孔211的内侧壁与电声器件22之间设有防水件23,且防水件23环绕设置于出音孔211的外周。当固定件24与壳体21固定连接时,电声器件22被夹持固定在壳体21的内侧壁(即壳体21开设有出音孔211的内侧壁)和固定件24之间,进而挤压防水件23使其产生形变,从而密封壳体21的内侧壁与电声器件22之间的间隙,以在壳体21的内侧壁与电声器件22之间形成防水界面。
本申请实施例提供的电声组件,通过在壳体的内侧壁设置防水件,以及通过固定件与壳体配合夹持固定电声器件,以使得电声器件挤压防 水件产生形变,密封壳体的内侧壁与电声器件之间的间隙,进而在壳体的内侧壁与电声器件之间形成防水界面,从而避免水汽进入壳体内部而损坏壳体内部的电路结构。另外,本申请实施例直接通过防水件与电声器件配合形成防水界面,简化电声组件的防水界面,降低防水失效风险。
可以理解的,电声器件22本身具有较高的防水级别,不易被外部水汽进入损坏,但水汽容易进入壳体21内部而损坏壳体21内部的电路结构,如电路板与电声器件22之间的电路连接结构。本申请实施例与第一实施例的区别在于:第一实施例通过在音腔支架的端部***与壳体支架孔的内侧壁之间的缝隙设置防水界面,属于侧压防水;而本申请实施例通过在壳体的内侧壁与电声器件之间形成防水界面,属于正压防水。应理解,在一定程度上,正压防水相较于侧压防水具有一定的优势。
结合参阅图5和图6,图6是图4实施例中电声组件20沿B-B向的部分截面结构示意图,壳体21的内侧壁设有环形凹槽212,该环形凹槽212环绕于出音孔211的***设置,且用于容置防水件23。环形凹槽212沿背离电声器件22的方向凹陷形成,且朝向电声器件22方向的投影位于电声器件22的出音面,以使得电声器件22可以全面挤压防水件23,进而使得防水件23可以完全密封电声器件22与壳体21的内侧壁。
防水件23填充于环形凹槽212,且呈环形状以与环形凹槽212相适配。具体的,防水件23与环形凹槽212的形状相适配,以使得防水件23可以填满环形凹槽212,提升防水密封性。进一步地,防水件23沿朝向电声器件22的方向凸出于环形凹槽212。本申请实施例提供的电声组件20装配完成时,防水件23置入或嵌入环形凹槽212内,环形凹槽212能够对防水件23起到定位的作用,使防水件23不易在壳体21与电声器件22之间发生偏位或脱落,从而进一步提高壳体21内部的防水效果以及电声器件22的装配稳固性。
进一步地,防水件23可以为硅胶圈,防水件23填充于环形凹槽212并凸出于环形凹槽212,电声器件22在装配时挤压防水件23,以使得防水件23产生形变,进而在电声器件22与壳体21的内侧壁之间的缝隙形成防水界面。当然,在其他实施方式中,防水件23也可以为橡胶 圈、塑胶圈等弹性防水胶圈。
在本申请部分实施例中,防水件23与壳体21一体成型。具体而言,可以采用注塑成型的方式一体成型防水件23与壳体。
当然,在其他实施方式中,可以通过点胶的方式在壳体21上形成防水件23。进一步地,通过成型工艺在壳体21的内侧壁形成环形凹槽212,然后通过点胶机将液态防水胶整圈点在环形凹槽212内,待液态防水胶固化后即形成防水件23。可以理解的,液态防水胶可以是UV防水胶、液态硅胶等液态胶体。
进一步地,在壳体21内侧壁形成防水件23后,固定件24与壳体21配合夹持固定电声器件22,以使得电声器件22挤压防水件23使其产生形变,进而形成壳体的内侧壁与电声器件之间的防水界面,即电声器件22的出音面与防水件23过盈配合压紧形成防水界面。
其中,固定件24与壳体21固定连接。结合参阅图7,图7是图4实施例中固定件24的结构示意图,固定件24包括顶持部241和固定部242。顶持部241用于与壳体21的内侧壁配合夹持电声器件22,即电声器件22夹持在壳体21的内侧壁与顶持部241之间。固定部242设于顶持部241的外周缘,并与壳体21固定连接。
在部分实施方式中,顶持部241和固定部242一体成型。当然,在其他实施实施方式中,顶持部241和固定部242可以分别单独成型后,固定连接在一起形成固定件24。
可以理解的,固定部242至少设于顶持部241的一端,以用于与壳体21固定连接。例如,固定部242可以设有两个,分别位于顶持部241的相对两端,以与壳体21形成稳定的固定结构。
进一步地,壳体21的内侧壁设有定位槽213,固定部242设有固定孔,固定孔与定位槽213配合固定连接固定件24与壳体21。具体而言,固定孔与定位槽213通过螺丝固定连接。当然,在其他实施方式中,固定部24与壳体21还可以通过诸如卡扣、滑扣等方式固定连接。
结合参阅图8,图8是图4实施例中壳体21的部分结构示意图,在本实施例中,固定部242设有两个,分别位于顶持部241的相对两端。
具体而言,固定部242包括第一固定部2421以及第二固定部2422,第一固定部2421以及第二固定部2422分别位于固定件24的两侧。第一固定部2421上开设有第一固定孔2431,第二固定部2422上开设有第二固定孔2432。壳体21的内侧壁设有分别与第一固定孔2431以及第二固定孔2432对应的第一定位槽2131和第二定位槽2132。其中,第一固定孔2431与第一定位槽2131配合固定连接,第二固定孔2432与第二定位槽2132配合固定连接。
需要说明的是,本申请中的术语“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。
在本申请实施例中,以第一固定孔2431与第一定位槽2131通过第一螺丝251固定连接、第二固定孔2432与第二定位槽2132通过第二螺丝252固定连接为例。
其中,第一固定孔2431的轴心线大体上平行于出音孔211的出音方向(如图7或图8所示的X方向),第二固定孔2432的轴心线大体上垂直于出音孔211的出音方向,即第二固定孔2432的轴心线大体上平行于图7或图8所示的Z方向。换言之,第一固定孔2431的轴心线与第二固定孔2432的轴心线大体上垂直,以在多个方向上对固定件24进行限位固定。
进一步地,第一定位槽2131在壳体21的内侧壁沿背离电声器件22的方向凹陷形成,壳体21的内侧壁朝向电声器件22的方向设置有凸块215,第二定位槽2132形成于凸块215上。第一定位槽2131的轴心线大体上平行于第一固定孔2431的轴心线,第二定位槽2132的轴心线大体上平行于第二固定孔2432的轴心线。
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。
请参阅图9,图9是图4实施例中固定件24与电声器件22配合时的结构示意图,固定件24的顶持部241包括顶持面2411以及设于顶持面2411相对两端的限位面2412。其中,电声器件22背离防水件23的端面顶持于顶持面2411,限位面2412夹持于电声器件22的相对两侧。
具体而言,在出音孔的出音方向上,顶持面2411与电声器件22背离防水件23的端面接触连接,以在固定件24与壳体21固定连接时抵顶于电声器件22以挤压防水件23。
在本申请部分实施例中,还设置有防尘网以阻挡外部的灰尘进入壳体内部。具体而言,请参阅图10,图10是本申请部分实施例中电声组件20的结构示意图,电声组件20还包括防尘网26。其中,防尘网26设于壳体21的内侧壁,且覆盖于壳体21上的出音孔211,以用于防止灰尘从出音孔211进入壳体21内部。
进一步地,防尘网26与壳体21的内侧壁粘接连接。例如,可以通过双面胶将防尘网26粘接于壳体21的内侧壁。
本申请实施例提供的电声组件,通过在壳体的内侧壁设置防水件,以及通过固定件与壳体配合夹持固定电声器件,以使得电声器件挤压防水件产生形变,密封壳体的内侧壁与电声器件之间的间隙,进而在壳体的内侧壁与电声器件之间形成防水界面,从而避免水汽进入壳体内部而损坏壳体内部的电路结构。另外,本申请实施例直接通过防水件与电声器件配合形成防水界面,简化电声组件的防水界面,降低防水失效风险。同时,通过正压防水提高电声器件的防水可靠性,且组装工艺较为简易,降低成本,简化零件设计,从而降低整机的制造成本。
可以理解的,在本申请的第一实施例中,通过在音腔支架的端部***套设防水圈,并与壳体支架孔的内侧壁配合形成侧压防水,对壳体支架孔的尺寸精度有一定的要求。在本申请的第二实施例中,通过在壳体的内侧壁设置防水件以与电声器件配合形成正压防水,对壳体的尺寸精力要求相对较低,易于加工。
