Description

全方位发声式音箱及其制造方法 技术领域
本发明涉及一种音箱,特别涉及一种全方位发声式音箱,其能够均匀地向其周围发出声音。
背景技术
目前市场上的音箱设备的喇叭系统一般设置在音箱箱体的同一侧,其声音从其一侧发出,所以,处于这种音箱设备的不同方位的听众所听到的由这种音箱设备发出的声音也不尽相同,很难达到音效的均一性。在一些场合,例如音乐会场,为了使各个地方的听众都能很好地体验听觉盛宴,通常会将许多个音箱设备布置于会场的周围,以使声音从会场的周围向中心传递。这种设置方式得到了广泛应用且能够达到很好的效果。但是,多个音箱分别布置和安装较为麻烦。另一方面,这些音箱需要连接至同一声音源,不仅需要较多的连接线还需要多这些连接线进行合理布置和安装,耗时、耗力,也不经济。
另外,这种将喇叭系统设置在音箱箱体的同一侧缝音箱设备在输入音频信号后,就会通过振动产生声音。当音箱设备特别是用于播放低音的低音炮的声音开得较大时,音箱自身也会产生强烈的震动,从而导致音箱自身产生跳跃或左右位移。而且这种强烈的震动也可能会带动周围的其他物品震动,从而损坏这些物品。例如,当音箱与电脑放置在一起时,音箱的震动会使电脑主机也跟着一起震动,从而可能损坏电脑内的部件如硬盘,主板等。所以,在对音响效果要求较高的场所,如音乐会现场,迪厅等,都需要用固定架来固定音箱或利用其他的方式来使音箱在运行时保持稳固。而且,为了减少震动所带来的不利影响以及为了得到更高质量的低音效果,用于播放低音的音箱设备通常非常笨重,体积较大,这样也不利于运输和携带。因此,需要一种体积小巧,又能改善音质效果特别是低音效果的音箱。

具体实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的第一个优选实施例只作为举例,本领域技术人员可以想到其他显而易见的变型。在以下描述中界定的本发明的基本原理可以应用于其他实施方案、变形方案、改进方案、等同方案以及没有背离本发明的精神和范围的其他技术方案。
如图1A至图4所示是根据本发明的第一个优选实施例的全方位发声式音箱,其包括一箱体10,以及设置于该箱体10的多个音响模组20,多个该音响模组20响应外部音频信号的输入而产生振动,从而产生预定的音效。该箱体10具有一中心线位置00。以该中心线位置00为轴心,这些音响模组20被环绕该中心线位置00均匀设置,以在该中心线位置00的不同方向产生音效。根据本发明的该第一个优选实施例,该音响模组20的数量为四。本领域技术人员应该能够理解,该音响模组20的数量为四仅仅是对本发明的示例而非限制。根据本发明的其他实施例,多个音响模组20也可以为的数量,例如六个、三个等。只要能够达到本发明的目的,本发明在这方面不受限制。下面将以该第一个优选实施例为例,以该音响模组20的数量为四对本发明进行介绍。
如图所示,以该中心线位置00为中心,该箱体10具有四个均等的模组空间100,以分别被用于设置上述四个音响模组20。如图所示,每一模组空间100具有一90°夹角,从而四个模组空间100平分以该中心线位置00为中心的360°角,从而被设置于四个模组空间100的四个音响模组20被紧密设置在一起,充分利用了空间并且相互起到支撑和固定的作用。以该中心线位置00位中心,每两个相邻音响模组20之间的夹角为90°,也就是说,该四个音响模组20围绕该中心线位置00均匀分布。
根据本发明的该第一个优选实施例,该箱体10包括一含色母的塑料射出面网11和一支架12。该支架12由高尺寸安定性的材料射成。该支架12被设置于该射出面网11,以形成多个与该音响模组20的尺寸、形状和数量相适应的该模组空间100。该模组20被分别插入该模组空间100。如图1A所示,该音响模组20与该支架10相互扣接,以对该音箱模组20进行固定,从而保证其被稳定于预设位置。
如图所示,每一音响模组20进一步包括一模组支架23。该模组支架23被 设置,以被用于安装、固定和保护该主振动单元21和该被动振动单元22。根据本发明的该第一个优选实施例,该模组支架23的形成借助上下两个模具。
如图3B所示,该连接元件50进一步包括一系列连接部件53,其被用于对该音响模组20的该模组支架23的拐角进行连接。值得一提的是,根据本发明的该第一个优选实施例,该连接部件53是通过超声波封合的方式进行连接。
如图所示,每一个音响模组20包括一主振动单元21和一被动振动单元22。也就是说,根据本发明的该第一个优选实施例的该全方位发声式音箱包括四个主振动单元21和四个被动振动单元22,共八个振动单元。该四个主振动单元21围绕该中心线位置00均匀分布。以该中心线位置00位中心,每两个主振动单元21之间的夹角为90°。该四个被动振动单元22绕该中心线位置00均匀分布。以该中心线位置00位中心,每两个被动振动单元22之间的夹角为90°。
根据本发明的该第一个优选实施例,该四个主振动单元21和该四个被动振动单元22围绕该中心线位置00均匀、交错分布。具体地,每一主振动单元21的两侧分别相邻设置一被动振动单元22。每一被动振动单元22的两侧分别相邻设置一主振动单元21。以该中心线位置00位中心,每一主振动单元21与相邻的被动振动单元22之间的夹角为45°。同样地,每一被动振动单元22与相邻的主振动单元21之间的夹角为45°。
如上所述,该主振动单元21和该被动振动单元22被围绕该中心线位置00均匀设置,从而八个振动单元21、22在围绕该中心线位置00的八个方向上发声,从而使该全方位发声式音箱在其周围均匀发声,使其声场更为均匀。也就是说,该全方位发声式音箱以该中心线位置00为中心向周围均匀辐射发声。
值得一提的是,如上所述,该音响模组20也可以为其他的数量。根据本发明的其他实施例,当该音响模组20的数量为N时,相应的,该模组空间100的数量为N。每个模组空间100则具有(360/N)°的夹角。相应地,以该中心线位置00位中心,每两个主振动单元21之间的夹角为(360/N)°,每两个被动振动单元22之间的夹角为(360/N)°。相应地,每一主振动单元21与相邻的被动振动单元22之间的夹角为(360/2N)°。N个主振动单元21和N个被动振动单元22被围绕该中心线位置00均匀设置,从而2N个振动单元21、22在围绕该中心线位置00的2N个方向上发声,从而使该全方位发声式音箱在其周围均匀发声,使其声场更为均匀。
值得一提的是,这种均匀的周围设置方式不仅有利于其发声的均匀,而且能够保持该箱体10的稳定。具体地,在该全方位发声式音箱工作过程中,多个主振动单元21同时向外振动。这种均匀环绕的设置方式使这些主振动单元21的振动得以抵消。同样地,在该全方位发声式音箱工作过程中,多个被动振动单元22同时向内振动。这种均匀环绕的设置方式使这些被动振动单元22的振动得以抵消。从而该全方位发声式音箱更加稳定。
值得一提的是,根据本发明的该第一个优选实施例,该主振动单元21以及该被动振动单元22的数量均为四,是偶数。因此通过上述均匀围绕的方式排列的每一主振动单元21的相反方向的对应位置都设置另一个主振动单元21。每一被动振动单元22的相反方向的对应位置都设置另一个被动振动单元22。偶数个主振动单元21在该箱体10上中心对称地设置。偶数个被动振动单元22也在该箱体10上中心对称地设置,更具体地,这些主振动单元21在该箱体10上呈反向中心对称地设置,这些被动振动单元22也在该箱体10上呈反向中心对称地设置。值得一提的是,在本发明的这个第一个优选实施例中,该音箱包括四个主振动单元21以及四个被动振动单元22。该主振动单元21各自连接到外部的音源以响应音频信号的输入而振动产生音效,因此这些主振动单元21互相呈中心对称地设置,从而这些主振动单元21在振动时,各自会朝向相反的方向产生振动。如图所示,在一个振动过程中,四个主振动单元21的振动方向都朝向外部,这使得每一个主振动单元21的相反一侧都有另外一个主振动单元21产生与之产生的振动方向相反的振动。也就是说,每两个相应主振动单元21的振动方向刚好相反,而整个该箱体10相当于没有受到明显偏向于某一个振动方向的作用力,从而得以保持平衡稳定。同样地,在一个振动过程中,四个被动振动单元22的振动方向都朝向外部,这使得每一个被动振动单元22的相反一侧都有另外一个被动振动单元22产生与之产生的振动方向相反的振动。也就是说,每两个相应被动振动单元22的振动方向刚好相反,而整个该箱体10相当于没有受到明显偏向于某一个振动方向的作用力,从而得以保持平衡稳定。
更值得一提的是,在本发明的这个第一个优选实施例中,四个主振动单元21用于带动四个被动振动单元22而使四个被动振动单元22产生振动。也就是说,四个被动振动单元22没有直接连接到外部的音源,其振动效果来源于四个主振动单元21的驱动。更具体地,四个主振动单元21在产生振动时,会相应地挤压该箱体10内的空气,该箱体10内的空气的振动的作用于四个被动振动单元22上,从而使四个被动振动单元22接着产生振动,从而四个被动振动单元22也得以产生音效。
因为四个被动振动单元22也能产生音效,这样就使该音箱的音质效果得到明显改善,特别是改善了该音箱的低音效果。这样该音箱便不用制成体积庞大,整体非常笨重。因为,本发明的这种全方位发声式音箱并且利用该主振动单元21与该被动振动单元22的搭配,可以产生理想的音质效果,特别是改善了低音的音质效果,从而使该音箱趋于小巧,方便携带和运输。
值得一提的是,一个该主振动单元21可以用于带动一个该被动振动单元22,也就是说它们可以共用一个空气振动腔。在本发明的这个第一个优选实施例中,该箱体10形成一振动腔100,在该振动腔100的周围分别设置有该主振动单元21和该被动振动单元22。也就是说,这些主振动单元21和被动振动单元22具 有相同的空气振动腔。
如图所示,当四个主振动单元21振动方向向外时,受到该振动腔100内的空气的影响,四个被动振动单元22会相应地具有方向向内的振动。也就是说,该振动腔100内的空气相当于受到了来自四周的均衡作用力,从而保持在该振动腔100内,而不是受到明显偏向于某一个方位的作用力,导致作用于该箱体10上而使该箱体10产生位移。也就是说,这些主振动单元21和被动振动单元22鼓动该振动腔100内的空气,而整个该箱体10也不会震动产生杂音,从而使得到的音质更加纯粹。
也就是说,本发明的音箱在工作时,其震动效果在该箱体10自身内部得以抵消从而保持平衡稳定,所以整个该箱体10在工作台面上不会产生较大的震动。
在本第一个优选实施例中,该音箱在该箱体10的八个侧面分别设置有八个安装孔以用于分别安装四个主振动单元21以及四个被动振动单元22。相应地,该安装孔的位置也呈中心对称地设置。
值得一提的是,该音箱10还设置有四个功放单元15。其分别被设置于四个音响模组的顶侧,以用于分别连接至四个主振动单元21,以给四个主振动单元21提供音频信号的输入。
四个主振动单元21可以是各种喇叭或扬声器的结构,其只要能响应音频信号的输入而振动产生音效即可。更具体地,在本发明中,各个该主振动单元21包括一主振动元件,该主振动元件可以是喇叭振膜或鼓纸等,该主振动单元21进一步包括设置在该主振动元件周围的悬边,以及必要的音圈,磁回系统等部件。该主振动单元21还包括一安装框架,以用于安装在该箱体10的安装孔上,从而与该箱体10密封地安装。值得一提的是,该悬边也可以直接安装在该箱体10的安装孔的表面上。
在有音频信号输入时,该音圈在该磁回系统的磁场的作用下来回运动,从而带动该主振动元件振动以产生音效,同时在该振动腔100中受挤压的空气会带动该被动振动单元22振动从而产生辅助音效。
值得一提的是,该磁回系统连接在一固定框上,该固定框与该安装框架组装在一起,从而形成了整个该主振动单元21。该固定框与该安装框架组装方式可以是卡扣连接,或者其他的方式如热压、超音波或者熔接等方法。
每个被动振动单元22包括位于中间的振动块221以及位于该振动块221周围的弹性悬边222,该弹性悬边222可以直接安装在该箱体10的安装孔的内表面上。在本实施例中,该被动振动单元22还包括一定位框架223。该定位框架223安装在该箱体10的安装孔中以与该箱体10密封地安装。
该全方位发声式音箱进一步包括一供能系统40。如图1B所示,根据本发明的该第一个优选实施例,该供能系统40被设置于该音响模组20的底侧,即整个音箱的底侧,具有稳定该音箱的作用。
从而,本发明的该音箱可以与一个外部音源设置如笔记本电脑通过无线连接或有线连接方式进行数据沟通,当使用者需要播放笔记本中的声音文件时,声音信息传送给该音箱,该音箱收到音频信号便可以播放这些声音文件。并且因为本发明的该音箱体积小巧,从而方便携带和使用,因为该主振动单元21和该被动振动单元22的搭配,音质效果又能得到很好的保证。
如图1A所示,该全方位发声式音箱进一步包括一系列连接元件50,其用于将该音箱的各个部件牢固连接,从而使该音箱的结构更为稳定。具体地,该连接元件50包括一系列用于连接相邻音响模组20的连接件51和一系列用于将该音响模组20固定于该箱体10的固定件52。根据本发明的该第一个优选实施例,每一固定件52具体实施为一插销。
值得一提是,参照图5A和图5B,本发明提供了一种音箱的制作工艺。在本发明中,需要制作该主振动单元21以及该被动振动单元22,然后将该主振动单元21以及该被动振动单元22与该箱体10—体地组装。
制作该主振动单元21的过程可以如下,将主振动元件,如合金材料的振膜或其他钢性材料的振膜,以及该安装框架放在橡胶射出模具中,经由注塑机一起嵌入射出成型,橡胶将该振膜包覆起来形成该主振动元件,同时橡胶也在该安装框架和该主振动元件之间形成该悬边。然后将该音圈连接于该主振动元件,该磁回系统通过U铁、磁铁、极片等经由塑料嵌入射出模具形成一体结构,从而成为含有一个固定框的磁回组件,该磁回组件与该安装框架通过卡扣、热压融合,超音波、热熔或其他方法固定在一起,从而形成了完整的主振动单元21。
类似地,该被动振动单元22的制作过程如下:将振动块221(也可以是钢性材料的振膜)与定位框架223放在橡胶射出模具中,经由注塑机一起嵌入射出成型,橡胶将该振膜包覆起来形成该振动块221,同时橡胶也在该定位框架223和该振动块221之间形成该弹性悬边222。
该箱体10为圆筒形并具有围绕其中心均匀分布的主振动单元安装孔以及均匀分布的被动单元安装孔。该主振动单元21以及该被动振动单元22分别通过必要的安装构件分别安装在这些安装孔中,从而形成整个该音箱。这些振动单元围绕其中心均匀分布,不仅减少甚至消除了整体音箱的震动,增强了低音效果,也更加美观。值得一提的是,如上已经提到过的,该主振动单元21也可以是传统的喇叭或扬声器。
值得一提的是,该主振动单元21的悬边以及该被动振动单元22的弹性悬边222呈褶皱状地分别设置在该主振动元件和该振动块221的周围,使该主振动元件和该振动块221的振动不会强烈地拉扯对应的安装框架和定位框架223而造成损坏。
本发明的音箱的该主振动单元21的该主振动元件,该悬边以及该被动振动单元22的该振动块221以及该弹性悬边222都可以制作成各种形状,在该第一 个优选实施例中,该主振动单元21的该主振动元件,该悬边可以是圆形,以及该被动振动单元22的该振动块221是和弹性悬边222也可以是圆形。当然也可以是其他的形状,例如长方形。也可以是其他多边形或椭圆形等形状。
该音箱的制作过程中还安装有功放系统30,该功放系统30分别与该主振动单元21连接,并且设置有无线网络模块如蓝牙模块、近场通讯模块、WIFI模块,这样该音箱可以通过无线连接的方式与其他的音源设备或音响设备交换数据信息。当音源设备发出指令并传输数据给该音箱时,该音箱便可以根据要求播放声音,值得一提的是,这两个主振动单元21功率相同。
该音箱的功放系统30也可以设置有连接界面元件,用于与其他音源设备或音响设备通过有线连接的方式来交换数据。例如通过有线连接与电脑、手机、个人数字助理、MP3、MP4、MP5和带音源的其他音箱等连接,以应这些音源设备或音箱的要求来播放音乐或其他声音。如图1B所示,该功放系统30被设置于该音响模组20的顶侧,即整个音箱的底侧,以方便与其他设置连接。该功放系统30的周围可以设置硅胶柔性面罩。
图6阐释了根据本发明的上述第一个优选实施例的该全方位发声式音箱的一种可替换实施例。如图所示,根据该可替换实施例的一音响模组20A包括两个主振动单元21A和一个被动振动单元22A。与上述第一个优选实施例中一个主振动单元21带动一个被动振动单元22不同,根据该可替换实施例,两个主振动单元21A带动一个被动振动单元22A。值得一提的是,根据本发明的其它实施例,也可以是多于两个主振动单元21A带动一个被动振动单元22A,或者是一个主振动单元21A带动多个被动振动单元22A。只要能够实现本发明的目的,本发明在这方面不受限制。
由上述描述和说明书附图可以看出,根据本发明的上述第一个优选实施例的该全方位发声式音箱发出的声音围绕一个中心向四周发散而不是像传统音箱中的多个音箱模组朝向同一方向或者相反的两个方向发声。这种向周围均发声的设置使该全方位发生式音箱的音效更好。
图7阐释了根据本发明的上述第一个优选实施例的该全方位发声式音箱的一种可替换实施例。根据该可替换实施例的该全方位发声式音箱包括一组围绕中心均匀设置的音响模组20B。与上述第一个优选实施例不同的是,该音响模组20B相互牢固连接,以形成一正多边形音箱。根据本发明的该可替换实施例,该全方位发声式音箱为八角形。
如图所示,每一音响模组20B包括一主振动单元21、一被动振动单元22和一模组支架23B。该模组支架23B被设置,以被用于安装、固定和保护该主振动单元21和该被动振动单元22。根据本发明的该第一个优选实施例,该模组支架23B的形成借助两个模具M1和M2
图8是根据本发明的上述第一个优选实施例的该全方位发声式音箱的该音 响模组的一模组支架的制作工艺示意图。如图8所示,为适应该模组支架23B的形状,该模具M1包括一顶模具M11和一对侧模具M12,其中该侧模具M12被设置于该顶模具M11的两侧。该侧模具M12被用于形成安装该主振动单元21和该被动振动单元22的安装孔。如图8所示,退模时,拉起该顶模具M11时会先把侧模具M12拉起来。等侧模具M12被拉起来后,整个模具M1才被拉起来。这是简单的滑块方式。
说明书附图之图9和图10阐释了根据本发明的第二个优选实施例的一全方位发声式音箱。如图9所示,该全方位发声式音箱包括多个均匀环绕设置的音响模组20C。
参考说明书附图之附图11和图12,依根据本发明的该第二个优选实施例,每一音响模组20C包括一主振动单元21C、至少一被动振动单元22C以及一模组支架23C。根据本发明的该第二个优选实施例,该主振动单元21C具体实施为一主振动喇叭。
该主振动单元21C能够响应音频信号的输入而振动发声,该被动振动单元22C能够响应该主振动单元21C的振动而振动,以产生辅助音效,从而增强该音响模组20C的低频音效。
具体地说,参考说明书附图之图11和图12,该被动振动单元22C包括一振动元件221C、一悬边222C以及一框架223C,其中该振动元件221C位于中间,该框架223C被安装于该模组支架23C,其中该悬边222C在该振动元件221C和该框架223C之间延伸,以用于限定该振动元件221C的振动方向。具体地,该悬边222C用于限定该振动元件221C沿着一预设方向往复运动,并避免该振动元件221C在往复运动的过程中出现偏移。
更具体地说,该悬边222C具有一内侧边缘2221C和一外侧边缘2222C,其中该悬边222C的该内侧边缘2221C可以一体地延伸于该振动元件221C的外边缘,或者该悬边222C的该内侧边缘2221C可以通过胶水或者其他的粘着物被粘结于该振动元件221C的外边缘,其中该悬边222C的该外侧边缘2222C可以一体地延伸于该框架223C的内边缘,或者该悬边222C的该外侧边缘2222C可以通过胶水或者其他的粘着物被粘结于该框架223C的内边缘,从而使该悬边222C在该振动元件221C和该框架223C之间延伸。值得一提的是,该悬边222C也可以包裹该振动元件221C的表面。
该悬边222C具有弹性,例如该悬边222C可以由弹性材料制成,例如但不限于橡胶材料,从而当该第一被动振动器21响应该主振动单元21C的振动而振动时,如果该振动元件221C产生沿着该预设方向向上的位移时,该悬边222C沿着该预设方向向下拉动该振动元件221C,以使该振动元件221C具有返回初始状态的趋势和位移,相应地,如果该振动元件221C产生沿着该预设方向向下的位移时,该悬边222C沿着该预设方向向上拉动该振动元件221C,以使该振动元 件221C具有返回初始状态的趋势和位移。
另外,在该振动元件221C沿着该预设方向产生向上或者向下的振动的过程中,该悬边222C用于保证该振动元件221C仅沿着该预设方向产生向上或者向下的位移,从而该悬边222C通过防止该振动元件221C产生偏移的方式保证该音响模组20C的音效。
值得一提的是,尽管在附图11和图12中示出的该被动振动单元22C的该振动元件221C均呈跑道形,在本发明的该音响模组20C的其他示例中,该振动元件221C的形状还可以被实施为但不限于圆形、椭圆形、方形或者其他的多边形。
参考说明书附图之图11和图12,该被动振动单元22C的该悬边222C的截面形状呈拱形,即,该悬边222C具有一凸侧2223C和一凹侧2224C,该悬边222C的该凸侧2223C和该凹侧2224C相互对应,可以理解的是,该悬边222C的该凸侧2223C和该凹侧2224C在该悬边222C形成时一体地形成。
值得一提的是,在附图13A示出的该音响模组20D的第一个可替换实施例中,一被动振动单元22D的一悬边222D的截面形状还可以均呈“W”形。
在附图13B示出的该音响模组20D的第二个可替换实施例中,一被动振动单元22E的该悬边222E的截面形状还可以均呈“M”形。
在附图13C示出的该音响模组20D的第三个可替换实施例中,一被动振动单元22F的该悬边222F的截面形状还可均呈“S”形。
在附图13D示出的该音响模组20D的第四个可替换实施例中,一被动振动单元22G的该悬边222G的截面形状还可均呈倒置的“S”形。
在附图13E示出的该音响模组20D的第五个可替换实施例中,一被动振动单元22H的该悬边222H的截面形状还可均呈波浪形。
在附图13F示出的该音响模组20D的第六个可替换实施例中,一被动振动单元22I的该悬边222I的截面形状还可均呈锯齿形。尽管如此,本领域的技术人员可以理解的是,在该音响模组20D的其他示例中,其悬边的界面形状还可以是V”字形、倒置的“V”字形、“U形”、倒置的“U”形。
在附图14和图15示出的该音响模组20D的第七个可替换实施例中,一悬边222J进一步包括一内悬边部分2225J和一外悬边部分2226J,其中该悬边222J的该内悬边部分2225J和该外悬边部分2226J一体地形成,并使该悬边222J的截面形状呈拱形或者其他的形状,其中该悬边222J的该内悬边部分2225J的自由边缘形成该悬边222J的该内侧边缘2221J,该悬边222J的该外悬边部分2226J的自由边缘形成该悬边222J的该外侧边缘2222J。

值得一提的是,每个该内侧弹肋22252J也可以分别从该内悬边主体22251J向下地凸出于该内悬边主体22251J所在的平面,以在该内悬边部分2225J的下侧形成该第一凸起222521J,和在该内悬边部分2225J的上侧形成该第一凹槽222622J。
优选地,相邻两个该内侧弹肋22252J互相间隔地设置,并且多个该内侧弹肋22252J呈辐射状地且均匀地排列在该振动元件221J的周围,以起到将该振动元件221J的振动方向限制在该预设方向的作用。相应地,该悬边222J的该外悬边部分2226J包括一外悬边主体22261J和多个外侧弹肋22262J,其中每个该外侧弹肋22262J相互间隔地沿着环形方向被设置于该外悬边主体22261J,或者每个该外侧弹肋22262J相互间隔地沿着环形方向一体地形成于该外悬边主体22261J,并且每个该外侧弹肋22262J凸出于该外悬边主体22261J的表面,从而该外侧弹肋22262J在该外悬边部分2226J的一侧形成第二凸起222621J,和在该外悬边部分2226J的另一侧形成第二凹槽222622J。也就是说,每个该外侧弹肋22262J在该外悬边部分2226J的一侧凸出于该外悬边主体22261J所在的平面,和在该外悬边部分2226J的另一侧从该外悬边主体22261J所在的平面向内凹。
值得一提的是,每个该外侧弹肋22262J也可以分别从该外悬边主体22261J向下地凸出于该外悬边主体22261J所在的平面,以在该外悬边部分2226J的下侧形成该第二凸起222621J,和在该外悬边部分2226J的上侧形成该第二凹槽222622J。
优选地,相邻两个该外侧弹肋22262J互相间隔地设置,并且多个该外侧弹肋22262J呈辐射状地且均匀地排列在该振动元件221J的周围,以起到将该振动元件221J的振动方向限制在该预设方向的作用。
值得一提的是,每个该内侧弹肋22252J和每个该外侧弹肋22262J可以一一对应地设置。也就是说,该悬边222J的该内悬边部分2225J的每个该内侧弹肋22252J都对应匹配有该外悬边部分2226J的每个该外侧弹肋22262J,这样,该悬边222J可以包括多组弹肋,其中每组该弹肋分别包括该内悬边部分2225J的一个该内侧弹肋22252J和该外悬边部分2226J的一个该外侧弹肋22262J。每组该弹肋沿着环形方向相互间隔地排列。可以理解的是,每组该弹肋的排列形状与该悬边222J的形状一致,例如当该悬边222J呈大致的圆环形时,每组该弹肋可以沿着径向方向排列。
在附图16和图17示出的该音响模组20D的第八个可替换实施例中,该悬 边222K的表面设有多个限位肋2227K,其中每个该限位肋2227K一体地延伸在该振动元件221K和该框架223K之间,以在该振动元件221K和该框架223K之间形成高低起伏的结构。
该悬边222K的该限位肋2227K用于加强该悬边222K的限位作用,以防止该振动元件221K在振动时偏离附该预设方向。具体地说,该振动元件221K在沿着附该预设方向振动时,如果该振动元件221K将要偏离该预设方向而产生偏移时,对应的该限位肋2227K产生反向的拉力,以抵消引起该振动元件221K产生偏移的偏移力。
值得一提的是,该限位肋2227K可以是沿着与对应的该振动元件221K的外周表面和对应的该框架223K的内周表面垂直的方向延伸,如附图16示出的那样。在另外的示例中,该限位肋2227K也可以沿着该振动元件221K的径向方向延伸或者倾斜地延伸,该限位肋2227K的这些排列方式可以产生相应的沿着这些方向的拉力,从而有效地防止该振动元件221K沿着这些方向产生偏移。
还值得一提的是,每个该限位肋2227K可以均匀地排列在该振动元件221K的周围,并且可以相对于该振动元件221K的中心呈对称地布置。在附图16示出的这个示例中,该限位肋2227K包括一左侧限位肋22271K和一右侧限位肋22272K。当该振动元件221K沿着该预设方向往复振动时,如果该振动元件221K想要向左偏移时,会立即受到该右侧限位肋22272K向右的反向拉力,从而阻止该振动元件221K产生向左的偏移。反之,如果该振动元件221K想要向右偏移时,会立即受到该左侧限位肋22271K向左的反向拉力,从而阻止该振动元件221K产生向右的偏移。这样,该悬边222K能够有效地将该振动元件221K的限位方向限制在沿着附该预设方向。

该悬边222L的每个该波形限位段2228L用于限位作用,以防止该振动元件221L在沿着附该预设方向振动时出现偏移的不良现象。具体地说,当该振动元件221L将要偏离该预设方向而产生向某个方向的偏移时,对应的该波形限位段2228L产生相反方向的拉力,以抵消引起该振动元件221L产生偏移的偏移力。值得一提的是,每个该波形限位段2228L可以均匀地排列在该振动元件221L的周围,并且可以相对于该振动元件221L的中心呈对称地布置。
参考说明书附图之图18,该悬边222L的多个该波形限位段2228L包括一左侧波形限位段22281L和一右侧波形限位段22282L。当该被动振动单元22L响应该主振动单元21的振动而振动时,该振动元件221L沿着附该预设方向往复运动,如果该振动元件221L想要向左偏移时,会立即受到该右侧波形限位段22282L 向右的反向拉力,从而阻止该振动元件221L产生向左的偏移。反之,如果该振动元件221L想要向右偏移时,会立即受到该左侧波形限位段22281L向左的反向拉力,从而阻止该振动元件221L产生向右的偏移。这样,该悬边222L能够有效地将该振动元件221L的限位方向限制在沿着附该预设方向。
另外,该悬边222L的每个该波形限位段2228L分别包括一振动元件连接端22283L和一框架连接端22284L,其中该振动元件连接端22283L在沿着圆周方向的截面上其截面形状可以呈拱形,并与该振动元件221L的外边缘连接,其中该框架连接端22284L被用于和该框架223L相连接。
进一步地,该振动元件连接端22283L具有两下侧连接点222831L、222832L,和一上侧连接点222833L,其中该两下侧连接点222831L、222832L和该上侧连接点222833L之间的连线可以呈三角形。而分别从该两下侧连接点222831L、222832L和该上侧连接点222833L向该框架223L的边缘延伸得到三个连接点222841L、222842L、222843L,其中这三个连接点222841L、222842L、222843L都形成在该框架连接端22284L,而这三个连接点222841L、222842L、222843L之间的连线呈弧形线段。也就是说,在这个实施例中,该波形限位段2228L具有内缘和外缘,其与该振动元件221L的外边缘相连接的内缘呈波形或者呈拱形,其与该框架223L的边缘相连接的外缘呈弧形,并且位于垂直于该振动元件221L的中心轴的同一个平面上。

进一步地,在本发明的该第三个优选实施例中,该振动单元213N的该第一振动元件2131N被连接于该第二振动元件2132N。该第二振动元件2132N的外周边缘被连接于该被动悬边2121N的内边沿,即该第二振动元件2132N的该第一振动主体21321的外周边缘213211N连接于该被动悬边2121N的该被动悬边内缘21211N;该被动悬边2121N的外边沿被连接于该第一框架2111N的内框部,即该被动悬边2121N的该被动悬边外缘21213N被连接于该第一框架主体 21111N的该第一框架内框部211111N;该第一框架2111N的外框部被连接于该第二框架2112N;该第二框架的内框部被连接于该制动悬边2122N的外边沿,即该制动悬边2122N的该制动悬边外缘21223N连接于该第二框架主体21121N的该第二框架内框部211211N;该制动悬边2122N的内边沿被连接于该连接体216N,即该连接体216N的该连接体外延部2163N被连接于该制动悬边2122N的该制动悬边内缘21221N;该连接体216N的顶部边沿被限位于该第二振动元件2132N的该环形连接体限位凹槽213213N内。这样,该第一框架2111N、该被动悬边2121N、该振动单元213N以及该连接体216N形成该支撑腔2000N。
进一步地,在本发明的该第三个优选实施例中,由于该第二框架2112N被设置于该第三框架主体21131N的顶部,即被设置于该第三框架安装台211311N,从而该第三框架2113N被连接并支撑该第二框架2112N,进而,该第三框架2113N、该制动悬边2133N、该连接体216N以及该第二框架2112N形成该振动腔1000N,该音圈214N和该磁回单元215N被容纳于该振动腔1000N内。
因此,由于设置了平行对扣式的该双悬边单元212N以及该连接体216N,该框架腔3000N被分隔为两个横向分布的重叠式的该支撑腔2000N和该振动腔1000N,从而在保证低音效果的质量同时,显著降低了主振动单元21N整体的厚度。
在降低了主振动单元21N整体的厚度的整体的厚度的同时,由于设置了该连接体216N和该双悬边单元212N,该主振动单元21N的低音效果也得到了提高。当该主振动单元21N被通电之后,由于电磁感应,该音圈214N能够响应音频信号的输入而被驱动进行轴向上的往复运动,例如当该主振动单元21N为附图中竖直放置时,该音圈214N能够被驱动进行纵向的往复运动。由于该音圈214N的上部靠近该振动单元213N,因此,该振动单元213N能够被该音圈214N的往复运动所驱动而产生振动。由于平行对扣式的该双悬边单元212N以及该连接体216N以及该框架组件211N的支撑作用,该振动单元213N能够以均匀的振幅仅在一个方向上往复地运动。进而能够保证音效尤其是低音效果的还原。
值得一提的是,如图26所示,该双悬边单元212N的该被动悬边2121N和该制动悬边2122N为平行对扣地设置,尤其需要指出的是,该被动悬边主体部21212N具有一被动拱形环腔212120N,该制动悬边主体部21222N具有一制动拱形环腔212220N,该被动拱形环腔212120N的深度L1在数值上和该制动拱形环腔212220N的深度L2相等。也就是说,虽然在本发明的该第三个优选实施例中,由于该被动悬边2121N需要鼓动空气而被设计为大直径的,该制动悬边2122N整体的尺寸与该被动悬边2121N相比为小尺寸的,但是该制动悬边2122N的拱形结构和该被动悬边2121N的拱形结构的弧度和凹角等在数值上是固定一样的。当然,本领域的技术人员可以理解的是,只要该制动悬边2122N和该被动悬边2121N的各拱形结构形成的各环形腔体的深度和腔体开口的宽度相同, 该制动悬边2122N和该被动悬边2121N的厚度可以不相同,本发明在这一方面并不受此限制。该制动悬边2122N能够对该被动悬边2121N产生制动效果。
值得一提的是,只要该制动悬边2122N和该被动悬边2121N所形成的凸起的深度在数值上相同,该制动悬边2122N和该被动悬边2121N所形成的凸起的形状可以不受限制,除了可以是本实施例中平行对扣的拱形结构,也可以是凸起方向一致的拱形结构,当然也可以不是拱形凸起结构,例如在其他实施例中,其横截面可以呈弓形、拱形、三角形、四边形、多边形、半圆形、半椭圆形、U形、V形等。
值得一提的是,该双悬边单元212N不仅能够防止该振动单元213N非轴向上的晃动和偏移,而且要能够保证该振动单元213N具有足够大的振幅,即足够大的轴向位移,从而保证该振动单元213N的冲程能够理想地再现低音。
值得一提的是,本发明的该双悬边单元212N是由弹性材料制成。值得一提的是,该双悬边单元212N的该被动悬边2121N和该制动悬边2122N的横截面形状为环形,也就是说该被动悬边主体部和该制动悬边主体部在横向上都是首尾连接一体形成环形状,也就是说,该被动悬边孔21210N和该制动悬边孔21220N都为圆形孔。本领域的技术人员可以理解的是,上述形状仅仅作为举例,本发明并不受此限制,在其他实施例中,该双悬边单元212N的该被动悬边2121N和该制动悬边2122N的横截面形状也可以选自环形、三角形、四边形、多边形等。
值得一提的是根据本发明的全方位发声式音箱可以供投影机客户使用,其可以于投影机分别设置,也可以与投影机相互连接。
本领域的技术人员应理解,上述描述及附图中所示的本发明的实施例只作为举例而并不限制本发明。本发明的目的已经完整并有效地实现。本发明的功能及结构原理已在实施例中展示和说明,在没有背离该原理下,本发明的实施方式可以有任何变形或修改。
