本实施例的电子设备可以是包括遥控器、手机和音箱在内的任意一种需要进行音频收集或者识别的设备,其他例示性的电子设备例如可以是录音笔、门禁系统等。其中,当电子设备包括遥控器时,该遥控器可以为可移动平台的遥控终端,可移动平台可以包括但不限于飞行器、车、船等。
为了描述更加简洁,以下通过对遥控器进行详细的介绍以更好的展示本实施例的技术方案,但本领域技术人员应该理解,通过对下述遥控器的结构进行适应性的改变即可将下述涉及到麦克风及其安装支架、以及侧壁的配合结构等应用到其他电子设备中,例如上述手机或者音箱内。
图1为本发明实施例提供的遥控器的下壳体的结构示意图。如图1所示,本实施例的遥控器的外壳可以包括盖合在一起的上壳体和下壳体1,图1中示出了外壳体的下壳体1部分。具体的,下壳体1包括下表面11以及围设在下表面11的外边沿的侧壁13。例如,参见图1,下壳体的侧壁13可以包括相对设置的底壁13a和顶壁(图中未示出),以及位于底壁13a和 顶壁之间的第一侧壁13b和第二侧壁13d。可以理解,在另外一些示例中,图1中围设在下表面11上的侧壁13也可以是围设在上壳体的上表面的外边沿上。在其他一些示例中,也可以是侧壁13的上半部分围设在上壳体的上表面的外边沿,而该侧壁13的下半部分则围设在下壳体1的下表面11的外边沿,从而当上壳体和下壳体1盖合在一起的时候可以形成一个完整的侧壁13。
在外壳上开设有第一声孔,以便与下文将要描述到的麦克风安装支架的第一定位柱相配合。该第一声孔可以安装在外壳的顶面(如上壳体)、底面(如第一壳体1的底部)或者侧壁13上,以下以开设在侧壁13上的侧壁声孔为例对本实施例的方案进行说明,一般来讲,在侧壁13上开设声孔收音效果相对较好。本领域技术人员应该理解,在外壳的顶面上形成的顶面声孔或者在外壳的底面上形成的底面声孔与麦克风支架的配合方式与侧壁13相类似,不再进行赘述。
具体来说,通过在侧壁13上开设有侧壁声孔,以便使得外壳外部的声波能够穿过该侧壁声孔传入到外壳的内部。在外壳内安装有包括一个或者多个麦克风组件21的收音装置2,以便接收从侧壁声孔传入的声波,从而提供给存储器进行存储以备后续播放或者处理。例如,可以将麦克风组件21接收到的声波传输到外壳内安装的处理器进行实时识别,并根据声波中所携带的控制指令使得该遥控器执行相应的操作。
图2为图1中的收音装置2在某个视角下的结构示意图;图3为图2中A位置的局部放大图;图4为图1中的收音装置2在另一个视角下的结构示意图;图5为图4中B位置的局部放大图;图6为图4的爆炸图;图7为图6中C位置的局部放大图。
如图1、图2、图4和图6所示,收音装置2可以包括四个麦克风组件21,这四个麦克风组件21沿着底壁(图1中为左侧)线性延伸。具体来说,在底壁上沿着长度方向开设有四个侧壁声孔,每个侧壁声孔均对应一个安装在外壳内的麦克风组件21,这四个麦克风组件21可以单独安装,或者也可以通过一个连接件连接在一起。例如,可以使用一个沿着底壁延伸的长条形连接板23作为连接件,并将这四个麦克风组件21沿着线性排列的方式安装在该连接板23上。
需要说明的是,虽然图1、图2、图4和图6中示意出了在底壁上沿直线的延伸方向设置四个麦克风组件21的方式。但是,本实施例并不限制安装在侧壁13上的麦克风组件21的数量、排布方式以及其位置。例如,在某些示例中,麦克风组件21可以多于或者少于四个,比如可以是1个、2个、3个、5个、8个等。容易理解,当麦克风组件21为多个时,这些麦克风组件21中的一部分可以沿着侧壁13的一部分线性排列(例如图1、图2、图4和图6中沿着底壁13a线性排列,当然也可以沿着顶壁、第一侧壁13b或者第二侧壁13d线性排列),或 者也可以是沿着侧壁13的一部分呈阵列排布(例如在底壁13a、顶壁、第一侧壁13b或者第二侧壁13d形成一个2×2阵列、3×3等)。当然,也可以在侧壁13的相对两个部分上各设置一个或者多个麦克风组件21(例如在顶壁和底壁13a上各设置至少一个麦克风组件21),或者这些麦克风组件21均匀环绕在侧壁13的内部,从而在侧壁13的内部形成一个环形。
可以理解,当麦克风组件21包括多个时,这多个麦克风组件也可以在外壳中除侧壁的其它面上进行排列分布,此处不做具体限定。
通过在外壳内设置多个麦克风组件21,这样多个麦克风组件21都可以收集到遥控器外部的声音,但不同位置的麦克风组件21收集到的某个音源的强度是不同的,通过处理器内算法的处理,就可以提高处理器接收到的声音的强度,从而便于提高声音的识别精度以及降噪效果。容易理解,这些麦克风组件21一般比较适宜于设置在侧壁13朝向声源的方向,从而可以进一步提高对于声音的识别精度并降低噪音。以音箱而言,由于其侧壁13一般都会有部分朝向墙壁设置,则这部分侧壁13可以不设置或者尽量少设置麦克风组件21,以避免浪费并降低成本。
下面结合图3、图5和图7对本实施例的麦克风组件21进行介绍。本实施例的麦克风组件21,包括麦克风211、电路板213以及将要在下文中详细描述的麦克风安装支架215。其中,麦克风211安装在电路板213上,该电路板213则和麦克风安装支架215固定在一起,且麦克风211的声孔与形成在麦克风安装支架215内的支架声孔以及上述侧壁声孔同心对齐,以提高声波的传输效果,从而提高麦克风211的识别精度。具体来说,当麦克风211通过麦克风支架215安装到侧壁13上时,侧壁声孔、支架声孔和麦克风的声孔就形成了一个供位于电子设备外部的声源所发出来的声波传输的通道,且这个供声波传输的通道是个同心的孔道,从而避免了声孔错位或者弯折所带来的对声波传输的影响,进而提升了整个麦克风的性能。
在本实施例中,麦克风211可以是顶部拾音麦克风TOP MIC或者是底部拾音麦克风BOTTOM MIC。
在本实施例中,电路板213可以是印制电路板PCB,麦克风211可以固定在PCB上。该PCB可以设计成沿着侧壁13的一部分(例如底壁)延伸的长条形电路板,从而多个麦克风组件21可以沿线性或者呈阵列的方式安装在该长条形电路板上。当然,也可以将多个电路板213安装在上述沿着底壁延伸的连接板23上,一个或者多个麦克风组件21则对应安装在一个电路板213上,以降低制造成本。
在本实施例中,电路板213也可以包括柔性电路板FPC和安装板,该FPC固定在安装板上,例如可以通过胶粘的方式固定在该安装板上,而麦克风211可以通过安装板与FPC固定,如穿过安装板与FPC实现电连接。同样的,该安装板也可以沿着侧壁13的一部分(例如底 壁)延伸以作为用来连接多个麦克风组件21的连接板23,此时,固定在安装板上的FPC可以是沿着安装板延伸的一个长条形的FPC,或者是包括多个尺寸较小的FPC。
麦克风安装支架215可以通过螺栓、销钉等现有的固定方式与电路板213固定,或者也可以如图3、图5和图7所示的在电路板213上开设定位孔2131,并在麦克风安装支架215与电路板213接触的表面上形成定位柱,以便通过将定位柱插入定位孔2131内来将麦克风安装支架215和电路板213固定。在麦克风安装支架215上形成定位柱的方式将在下文进行具体的描述。
可选地,为了提高密封性,从而提高声波的传输效果,在本实施例中,可以在电路板213和麦克风211之间可以设置密封件,包括但不限于是硅胶以及隔音海绵等。同理的,在麦克风211支架与电路板213接触的表面以及电路板213之间也可以设置密封件,该密封件同样包括但不限于是硅胶以及隔音海绵等。
图8为本实施例提供的麦克风安装支架215的结构示意图。下面结合图8具体介绍本实施例的麦克风安装支架215。本实施例的麦克风211支架包括大致为圆角矩形的主体2151。可以理解,在其他一些示例汇总,主体2151也可以是其他形状的部件,例如圆形、椭圆形等。
主体2151包括有相对的上表面(即第一表面)和下表面(即第二表面),在下表面的合适位置(例如下表面11的中心)形成有第一定位柱2153,该第一定位柱2153用于穿设在侧壁声孔内,以实现麦克风安装支架215与侧壁13的定位。在第一定位柱2153和主体2151内形成有贯穿这二者的支架声孔,该支架声孔与侧壁声孔以及麦克风211的声孔同心设置。
具体来说,该第一定位柱2153可以是单独的零部件,通过焊接或者粘接等现有的固定方式固定在主体2151的底面上;或者,也可以将第一定位柱2153与主体2151通过一体成形的方式制成一体件。
可选的,如图8所示,第一定位柱2153可以形成有台阶面2153a,该台阶面2153a用于抵接在侧壁13的内表面上,以便提高麦克风安装支架215与侧壁13的密封性,从而提高声波的传输效果。
又可选地,为了避免外部的灰尘或者异物进入麦克风安装支架215的支架声孔内,还可以在侧壁声孔内设置防尘件,该防尘件抵靠在第一定位柱2153远离下表面11的端部(也即图8中的下端部)。具体来说,可以使用防尘膜或者防尘筛网作为上述防尘件。
本实施例的麦克风安装支架215,通过在主体2151的一个表面形成第一定位柱2153以便与侧壁声孔进行定位,并在主体2151和第一定位柱2153内形成贯穿于这二者的支架声孔,当通过该麦克风安装支架215将麦克风211安装到侧壁13上时,可以保证侧壁声孔、支架声孔以及麦克风211的声孔的同心度,从而提高麦克风211对声音的接收效果。
同时,当电子设备需要安装BOTTOM MIC时,通过设置麦克风安装支架,还可以避免现有技术中某些电子设备在外壳的侧壁13开设声孔时,需要通过折线路径(例如L形路径)来将麦克风声孔和侧壁声孔连通的问题,从而缩短了声音的传输距离,降低了声波的衰减,提高了麦克风211收音的清晰度。
在本实施例中,如图8所示,在下表面11上还可以在第一定位柱2153的外侧形成两个向下方延伸的卡爪2155,用于与侧壁13上所开设的卡口相配合,以便将麦克风安装支架215固定在侧壁13上。这两个卡爪2155可以围绕第一定位柱2153的外边沿均匀设置,或者也可以围设在第一定位柱2153的外边沿的任意合适位置。可以理解,在其他一些示例中,也可以不设置卡爪2155,而通过其他方式实现与侧壁13的固定,例如可以在第一定位柱2153上形成外螺纹、并在侧壁声孔的内表面形成内螺纹,以便将第一定位柱2153和侧壁声孔螺纹连接在一起。当然,在另外一些示例中,也可以在第一定位柱2153的外边沿设置一个或者两个以上的卡爪2155。
具体的,每个卡爪2155均可以包括支臂2155a以及与侧壁13的卡口相配合的卡扣部2155b,其中,支臂2155a的一端与主体2151的第二表面固定,该支臂2155a的另一端则与卡扣部2155b固定,且该卡扣部2155b往第一定位柱2153的方向延伸。当然,在其他一些示例中,卡爪2155也可以为其他的结构,例如卡扣部2155b可以往远离第一定位柱2153的轴线方向延伸。
如图3、图5和图7所示,在两个卡爪2155之间还可以设置用于套设在第一定位柱2153外的密封件217,该密封件217包括但不限于是硅胶以及隔音海绵等。当然,容易理解,当麦克风安装支架215不包括卡爪2155时,则该密封件217仅仅套设在第一定位柱2153外侧而已,并且在其他一些示例中,密封件217也不限于设置在两个卡爪2155之间,卡爪2155也可以穿过该密封件217。
可选地,在卡爪2155和本体之间设置有加强筋2159,以加强卡爪2155与本体的连接,降低其断裂的可能性。
继续参考图8,在本实施例中,还可以在上表面的边缘位置形成有两个第二定位柱2157,这两个定位柱围绕支架声孔的外边沿均匀设置。该第二定位柱2157则用于与开设在电路板213上的定位孔2131配合,当其穿设在电路板213的定位孔2131内时,可以实现麦克风安装支架215与麦克风211的定位。
应当理解,在上表面形成的第二定位柱2157也可以是一个或者两个以上,并且当第二定位柱2157为多个时,其可以围绕支架声孔的外边沿均匀设置,也可以仅仅是围绕支架声孔的外边沿。
最后应说明的是:以上实施方式仅用以说明本发明实施例的技术方案,而非对其进行限制;尽管参照前述实施方式对本发明实施例已经进行了详细的说明,但本领域的普通技术人员应当理解:其依然可以对前述实施方式所记载的技术方案进行修改,或者对其中部分或者全部技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本发明实施方式技术方案的范围。
