点音源模组扬声器及其制造方法 技术领域
本发明涉及一种扬声器及其制造方法，特别涉及一种点音源模组扬声器及其制造方法。
背景技术
现有的音频信号，通常是人为地将有声音源区分成高音和中低音，然后分别用不同的喇叭或扬声器播放高音和中低音。但是这是一种误解，因为是人的耳朵可以将声音区分为高音和中低音。也就是说现有技术中存在一定的认识盲区，即在现有技术中，声音需要通过机器设备分成高音和中低音不同频段，然后通过不同的设备来将声音还原播放，这样还原以后的声音到达人的耳朵后会使人听到整个高中低音的较佳的音质效果。但是，人的耳朵才是最精密的仪器，不需要将音源用机器设备人为地划分成高音段和中低段，只要音源传达到耳朵，耳朵会自动将这个音源区分成高音段和中低音段，然后使人能得到全音频段的听觉享受。也就说，不需要通过分频器将声音分成几个频段，中高频率段输出到中高频音箱，低频段输出到低音炮，而只需要一个音效设备，同时播放高中低频声音，人的耳朵自动能听到这些不同频段的声音。
发明内容

本发明的另一目的在于提供一种点音源模组扬声器，声音在录制时，高中低 音同时产生于一个音源点，这样声音在录制成音频信号时不需要区分为不同频段，而是直接传送到所述点音源模组扬声器播放，从而声音得以还原，并且人耳能自动将还原的声音区分成与录音现场相同的高中低音，从而能使人能最大程度地得到录音现场的声音效果。
本发明的另一目的在于提供一种点音源模组扬声器，因为声音地传送和播放过程中，不需要分频，从而相当于录音现场至播音现场的音源的点对点无损传送，从而保证了音质效果。

具体实施方式
如图1A至图4所示是根据本发明的一个优选实施例的点音源模组扬声器100的结构示意图。所述点音源模组扬声器100包括至少一主振动喇叭10以及至少一被动振动器20。所述主振动喇叭10响应音频信号的输入而振动产生声音，所述被动振动器20响应所述主振动喇叭10的振动而振动从而产生辅助音效。也就是说，所述被动振动器20不直接连接至音频信号，而是通过所述主振动喇叭的带动而产生振动。所述被动振动器20加强了整个所述喇叭的音质效果，特别是改善了低音效果。
音频信号到达本发明的所述点音源模组扬声器100后，可以同时播放高中低频段的音频信号，从而可以产生全频段的音效，以形成本发明所述的点音源。也就是说，使用本发明的所述点音源模组扬声器，所述音频信号不需要使用分频器将声音分成高音和中低音，然后通过不同的喇叭来播放对应的高音和中低音。而本发明的所述点音源模组扬声器可以同时播放高中低音，也就是所述点音源中包括了高中低音的全频段的音频声音。
当所述点音源模组扬声器100还原并播放声音时，相当于高中低音藉由所述点音源模组扬声器一起播放，从而当产生的声音传递至听者的耳朵时，耳朵会自动识别这些高音和中低音，从而得到全频段的音效体验。也就是说，音源现场录制的声音或其他方式得到的声音源，得以藉由所述点音源模组扬声器100而完整地还原，从而使听者能够享受到原始音源的音质效果。
如图中所示，本发明的这个优选实施例的所述点音源模组扬声器100包括一所述主振动喇叭10以及一所述被动振动器20。所述主振动喇叭10以及所述被动振动器20通过一模组壳体30组装在一起。所述主振动喇叭10以及所述被动振动器20可以分别组装在所述模组壳体30的同一侧面或者不同的侧面。在这个优选实施例中，所述主振动喇叭10以及所述被动振动器20组装在所述点音源模组扬声器100的两相反侧。也就是说，所述主振动喇叭10以及所述被动振动器20可以同轴地位于所述音源模组扬声器的相反两侧。
所述模组壳体30与所述主振动喇叭10以及所述被动振动器20形成一振动腔31，并且所述主振动喇叭10以及所述被动振动器20共用所述振动腔31，从而当所述主振动喇叭10响应音频信号的输入时，会鼓动所述振动腔31内的空气震动，从而产生声音。而当所述振动腔31内的空气振动时，会同时直接作用到所述被动振动器20，从而所述被动振动器20也相应地产生振动从而产生辅助音效。
也就是说，所述点音源模组扬声器100提供了所述振动腔31，而所述主振动喇叭10以及所述被动振动器20同时鼓动所述振动腔31内的空气，从而可以产生纯粹洁净的音效。
所述主振动喇叭10可以是各种传统结构的喇叭。其只要在音频信号输入时，产生振动从而发出声音即可。在本发明的这个优选实施例中，所述主振动喇叭10包括一振动体11，设置在所述振动体11周围的悬边12，连接至所述振动体11的音圈13，与所述音圈13协同作用的磁回系统14，以及其他必要的连接导线，端子等元件。所述主振动喇叭还包括一喇叭面板15，所述悬边12连接于所述喇叭面板15，所述音圈13，以及所述磁回系统14通过必要的连接部件连接到所述喇叭面板15，从而形成一体结构。必要的连接方式可以是卡扣、凹凸件配合、热熔、超音波连接等方式。例如所述磁回系统14连接于一安装框架16，所述安装框架16设置有定位孔161，所述喇叭面板15背面设置有定位柱151，所述定位柱151通过热熔的方式定位于对应的所述定位孔161中，从而使所述喇叭面板15与所述安装框架16连接在一起。值得一提的是，所述喇叭面板15与所述安装框架16安装在一起时，所述定位柱151可以沿着圆周方向互相间隔地设置，从而没有使所述振动体11与所述磁回系统14之间形成密闭的空间，而是留有间隙，这样所述振动体11振动时，可以与所述被动振动器20共同所述振动腔31。
所述被动振动器20包括中间的振动元件21以及位于周围的弹性悬边元件22。所述悬边元件22与所述模组壳体30的外表面一体地连接，或者通过一固定框架23连接到所述模组壳体30。
所述模组壳体30是一腔体，以用于形成所述振动腔31。所述模组壳体30延伸于所述喇叭面板15与所述固定框架23之间，从而在所述模组扬声器中形成一密闭的所述振动腔31。这样所述主振动喇叭10与所述被动振动器20可以纯 粹地鼓动所述振动腔31内的空气。
也就是说，所述振动腔31可以分成三部分腔室。所述主振动喇叭10的所述振动体11与所述磁回系统14之间形成一第一腔室311，所述被动振动器20的所述振动元件21与所述磁回系统14之间形成一第二腔室312，所述模组壳体30与内部组件如所述磁回系统14，所述安装框架16之内形成一第三腔室313。所述第三腔室313将所述第一腔室311与所述第二腔室312相连通。这样，所述第一腔室311内空气气压的变化会藉由所述第三腔室313传递至所述第二腔室312。因为所述第一腔室311，第二腔室312，以及所述第三腔室313的空气的鼓动，使所述主振动喇叭10与所述被动振动器20同时产生振动，以提供高中低全频段的点音源。
当所述主振动喇叭10的所述音圈13中接入音频信号时，所述音圈13在所述磁回系统14的作用下往复振动，从而带动所述振动体11振动，所述悬边12使所述振动体11沿着轴向的方向振动，所述主振动喇叭10的振动鼓动所述振动腔31内的空气振动，从而所述振动腔31内的空气的振动会进一步使所述被动振动器20的所述振动元件21振动，并且所述弹性悬边元件22使所述振动元件21沿着轴向来回往复运动，以使所述被动振动器20产生所述辅助音效。
更具体地，所述主振动喇叭10与所述被动振动器20同轴地产生振动。例如，沿着轴向方向，当所述主振动喇叭10的所述音圈13在所述磁回系统14的作用下向上振动时，与所述音圈13相连接的所述振动体11相应的向上振动，由于所述振动腔31内空气压力的关系，所述被动振动器20的所述振动元件21也相应的向上振动；当所述音圈13在磁回系统14的作用下向下振动时，与所述音圈13相连接的所述振动体11相应的向下振动，所述被动振动器20的所述振动元件21也相应的向下振动。也就是说，所述被动振动器20的振动元件21响应所述主振动喇叭10的所述振动体11的往复振动而对应的产生共轴的往复振动。
所述主振动喇叭10可以包括一连接体17，其由与所述悬边12同样的材料制成，并且所述连接体17一体地从所述悬边12延伸，并且连接到所述振动体11，如可以包覆所述振动体11的一个侧面或多个侧面。所述连接体17可以设置有多个开孔171，从而既节省了材料，又可以增强所述主振动喇叭10的美观效果。
类似地，所述被动振动器20也可以包括一连接元件24，其由与所述弹性悬 边元件22同样的材料制成，并且所述连接元件24一体地从所述弹性悬边元件22延伸，并且连接到所述振动元件24，如可以包覆所述振动元件21的一个侧面或多个侧面。所述连接元件24也可以设置有多个开孔，从而既节省了材料，又可以增强所述被动振动器20的美观效果。
所述主振动喇叭10的所述振动体11，所述悬边12，以及所述连接体17的制作以及所述被动振动器20的制作都可以通过嵌入射出工艺来完成。具体地，以所述被动振动器20的制作工艺为例，将形成所述振动元件21的一加重块，以及固定框架23放入至一制作模具中，然后通过嵌入射出工艺，液体材料如橡胶进入到所述制作模具中，并且到达所述加重块与所述固定框架23之间，以形成所述悬边元件22，并且橡胶材料包覆所述加重块，以形成所述连接元件24，这样就形成了一体结构。
也就是说，在本发明的这个优选实施例中，包括振动单元以及悬边单元的主主振动喇叭以及被动振动器的振动系统实质上可以是同样的结构，其由同样的模具制成，从而形成完全对称的结构。这样，鼓动所述振动腔31内的空气时，相当于是同样的振动系统在两个侧面鼓动空气，从而可以产生纯净的音效。
例如，所述主振动喇叭10的所述振动体11振动并且向外运动时，所述振动腔内的空气跟着朝向所述振动体11的方向运动，而所述被动振动器20的所述振动元件21会因为外界空气的压力而朝向所述振动腔31的内部运动。相反，当所述主振动喇叭10的所述振动体11振动并且向所述振动腔31的内部运动时，所述被动振动器20的所述振动元件21会向外运动。这样，所述振动腔31内的空气会产生和谐的振动，从而使产生的声音更纯粹，没有杂音。
如图17所示，本发明的所述点音源模组扬声器100可以串接在一起，并且安装在一支架40上，从而形成点音源模组扬声器100的组合，以组装成音箱。值得一提的是，所述支架可以制作成各种形状和尺寸，以适应不同环境。所述点音源模组扬声器100的数目也可以根据要求设置，并且所述点音源模组扬声器100中的所述主振动喇叭10和所述被动振动器20的数目也可以根据需要变化。并且在组装到所述支架40上时，本发明的点音源模组扬声器100也可以搭配其它具有与本发明不同结构的喇叭，从而使用者可以根据自己的喜好制作出符合自己要求的音效装置。
本发明还提供一种点音源模组扬声器的制造方法，如图5至图16中所示， 其包括步骤：
(a)将一主振动喇叭10和一被动振动器20同轴地设置；以及
(b)使所述主振动喇叭10与所述被动振动器20共用一振动腔31，当所述主振动喇叭10在响应音频信号的输入而振动产生声音时，所述被动振动器20相应振动产生辅助音效，从而得到全频段的点音源。
所述主振动喇叭10可以是传统结构的喇叭。
在所述步骤(b)中，可以通过一模组壳体30与所述主振动喇叭10和所述被动振动器20组合以形成密封的所述振动腔31。
在本发明中，所述主振动喇叭10可以由以下工艺制得。将U铁141，磁石142以及极片143放入模具中注塑，由注塑形成的连接件144制作成磁回系统14，当然也可以由其他传统方法制得，如传统的压合以及胶水粘接工艺。所述磁回系统14与安装框架16一体地通过注塑成型的方式形成。所述安装框架16上形成有多个定位孔161。然后安装音圈13以使所述音圈13与所述磁回系统14得以电磁感应而协同作用。注塑成型喇叭面板15，所述喇叭面板15形成有安装孔位，并且背面一体地形成有多个定位柱151。然后将形成所述振动体11的振膜以及所述喇叭面板15放入注塑模具中，然后通过嵌入射出工艺，液体材料如橡胶进入到所述注塑模具中，并且到达所述振膜与所述喇叭面板15之间，以形成所述弹性悬边12，并且橡胶材料包覆所述振膜，以形成所述连接体17。然后将所述音圈13与所述振动体11相连接，并且安装必要的导线以及接线端子等元件，将所述安装框架15与所述喇叭面板15通过所述定位柱151热熔于对应的定位孔161中的方式组装在一起，从而形成所述主振动喇叭10。
在本发明中，所述模组壳体30一端与所述喇叭面板连接，另一端连接于所述被动振动器20。所述被动振动器20的制作工艺，如上所述，将形成所述振动元件21的一加重块，模组壳体30放入至一制作模具中，然后通过嵌入射出工艺，液体材料如橡胶进入到所述制作模具中，并且到达所述加重块与所述模组壳体30的外边缘之间，以形成所述悬边元件22，并且橡胶材料包覆所述加重块，以形成所述连接元件24，这样就形成了一体结构。
然后，所述被动振动器20与所述模组壳体30的组合体，可以通过各种方式与所述主振动喇叭10的所述喇叭面板15组合，从而形成所述点音源模组扬声器。例如通过超声波的方式组装在一起。
值得一提的是，所述被动振动器20与所述模组壳体30的组合体之内也可以放置适量吸音材料如吸音棉50，用于调整所述点音源模组扬声器的音质。
在本发明的这个优选实施例中，所述模组壳体30可以是一中空结构，其包括一主体部32，以及一基底部33。所述基底部33与所述被动振动器20一体地成型并且形成一第二腔室312。所述主体部32环绕于所述主振动喇叭20的磁回系统14，音圈13等元件的外部，以形成一第三腔室313。所述振动体11与所述磁回系统14之间形成一第一腔室311，所述第一腔室311与所述第二腔室313通过所述第三腔室313相连通。
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。
由此可见，本发明之目的已经完整并有效的予以实现。本发明的功能及结构原理已在实施例中予以展示和说明，在不背离所述原理下，实施方式可作任意修改。所以，本发明包括了基于权利要求精神及权利要求范围的所有变形实施方式。

    (b)使所述主振动喇叭与所述被动振动器共用一振动腔，当所述主振动喇叭在响应音频信号的输入而振动产生声音时，所述被动振动器相应振动产生辅助音效，从而得到全频段的点音源。、
  15. 如权利要求14所述的方法，其特征在于，所述主振动喇叭是传统结构的喇叭。
  16. 如权利要求14所述的方法，其特征在于，在所述步骤(b)中，通过一模组壳体与所述主振动喇叭和所述被动振动器组合以形成密封的所述振动腔。
  17. 如权利要求14所述的方法，其特征在于，所述主振动喇叭由以下工艺制得：注塑成型具有安装孔位的喇叭面板，然后将形成振动体的振膜以及所述喇叭面板放入注塑模具中，然后通过嵌入射出工艺，液体材料如橡胶进入到所述注塑模具中形成所述振动体，并且到达所述振膜与所述喇叭面板之间，以形成所述弹性悬边，然后将形成有所述振动体，所述悬边的所述喇叭面板与一音圈以及一磁回系统组装在一起。
  18. 如权利要求17所述的方法，其特征在于，还包括步骤：将U铁，极片以及磁石放入模具中制作成所述磁回系统，所述磁回系统与一安装框架一体地通过注塑成型的方式形成；然后安装音圈以使所述音圈与所述磁回系统得以电磁感应而协同作用，然后所述安装框架与所述喇叭面板通过热熔接，超声波，或卡扣连接方式连接在一起。
  19. 如权利要求17所述的方法，其特征在于，所述安装框架上形成有多个定位孔，所述喇叭面板背面一体地形成有多个定位柱，通过热熔接方式使所述定位柱定位于对应的定位孔，从而使所述安装框架与所述喇叭面板组装在一起。
  20. 如权利要求17所述的方法，其特征在于，在上述振动体注塑过程中，形成所述弹性悬边的橡胶材料同时包覆所述振膜，以形成连接体，用于连接所述振膜与所述弹性悬边。
  21. 如权利要求14至20中任一所述的方法，其特征在于，所述被动振动器的制作工艺包括步骤：将形成振动元件的一加重块，模组壳体放入至一制作模具中，然后通过嵌入射出工艺，橡胶材料进入到所述制作模具中，并且到达所述加重块与所述模组壳体的外边缘之间，以形成所述悬边元件，并且橡胶材料包覆所述加重块，以形成所述连接元件，这样就形成了一体结构。
  22. 如权利要求21所述的方法，其特征在于，所述模组壳体一端与所述喇叭面板连接，另一端连接于所述被动振动器，从而形成所述振动腔。
  23. 如权利要求22所述的方法，其特征在于，所述被动振动器与所述模组壳体的组合体，通过热熔接，超声波，或卡扣与所述主振动喇叭的所述喇叭面板连接，从而形成所述点音源模组扬声器。
  24. 如权利要求23所述的方法，其特征在于，所述模组壳体是一中空结构，其包括一主体部，以及一基底部。所述基底部与所述被动振动器一体地成型并且在所述被动振动器所述振动元件与所述主振动喇叭的所述磁回系统之间形成一第二腔室，所述主体部环绕于所述主振动喇叭的所述磁回系统，所述音圈的外部，以形成一第三腔室，所述振动体与所述磁回系统之间形成一第一腔室，所述第一腔室与所述第二腔室通过所述第三腔室相连通。
