Description

扬声器振动系统 技术领域
本实用新型涉及扬声器技术领域，更为具体地，涉及一种扬声器振动系统。
背景技术
现有的扬声器包括外壳、磁路系统和振动系统，其中，振动系统包括音圈和振膜，振膜又分为多种类型，包括金属振膜、纸盆振膜和硅胶振膜等等，对于硅胶振膜，通常在其下侧粘结一个金属环，该金属环对硅胶振膜起到支撑固定的作用，但此种固定方式会存在以下问题：
1、牢固性较差；
2、不利于硅胶振膜的注塑成型；
3、硅胶振膜具有弹性，使得硅胶振膜与金属环的整体高度可变。
实用新型内容
鉴于上述问题，本实用新型的目的是提供一种扬声器振动系统，以解决金属环固定振膜不牢固，以及不利于硅胶振膜注塑成型的问题。
本实用新型提供的扬声器振动系统包括硅胶振膜以及结合于硅胶振膜下侧的金属环；硅胶振膜与金属环注塑结合；其中，金属环包括外部块体以及与外部块体相接的内部块体；内部块体的高度低于外部块体的高度，在内部块体与外部块体相接处形成台阶面；在硅胶振膜与金属环注塑结合时，对应所述台阶面处填充有硅胶；在内部块体上设置有向内凹陷的注胶孔，并且对应注胶孔的位置填充有硅胶。
此外，优选的结构是，外部块体的边缘设置有下凹的缺口，硅胶振膜注塑成型时对应缺口处填充硅胶。
另外，优选的结构是，外部块体为环状结构，包括四个直立边，缺口分别设置于四个直立边上。
此外，优选的结构是，缺口与内部块体连通，缺口的高度低于外 部块体的高度，并且与外部块体的高度相同。
再者，优选的结构是，注胶孔设置于外部块体与内部块体相接的位置。
此外，优选的结构是，注胶孔均匀设置于金属环的角部。
另外，优选的结构是，注胶孔竖向贯穿内部块体。
再者，优选的结构是，在硅胶振膜注塑成型时，外部块体形成挡墙，硅胶振膜的高度为外部块体的高度。
另外，优选的结构是，注胶孔的横截面为弧形。
再者，优选的结构是，金属环为不锈钢材质。
利用上述根据本实用新型的扬声器振动系统能够取得以下有益效果：
1、金属环内部形成的注胶孔能够避免注塑成型的硅胶振膜在水平方向和竖直方向的移动，并且可以勾住成型后硅胶振膜对应的凹陷处，防止硅胶振膜脱出；另外，注胶孔在金属环的角部位置设置，一方面考虑到该位置空间较大，另一方面也满足了产品本身的对称性需求。
2、金属环内、外部块体相接处形成台阶面，对应台阶面的区域填充硅胶形成硅胶振膜，由于外部块体没有进行减薄设置，其高度高于内部块体，且外部块体为不具有弹性的金属材料，硅胶振膜注塑成型时，外部块体形成挡墙，因此可以定位硅胶振膜的；另外，产品装配后该区域恰好被上壳压住，可对硅胶振膜起到一定的固定作用。
3、外部块体设置的缺口可以增加对硅胶振膜的压料面积，能够提高金属环固定硅胶振膜的效果，该缺口还可以均衡注塑模具内的压力，使得注塑后硅胶振膜的厚度趋于均衡。

在所有附图中相同的标号指示相似或相应的特征或功能。
具体实施方式
以下将结合附图对本实用新型的具体实施例进行详细描述。
为了深入地理解金属环在扬声器振动系统中的作用，首先对金属环与振膜的关系作出说明，一方面金属环起到固定振膜的作用，而该振膜为注塑成型的振膜，在下文中涉及到的振膜均以硅胶振膜为例，另一方面金属环起到配合振膜注塑成型的作用，将金属环与振膜模具配合使用，因此，振膜的形状与金属环的形状相同，如果振膜为圆形，金属环同样为圆形。
图1示出了根据本实用新型实施例的扬声器振动系统的结构，图2-图4分别示出了图1沿B-B线、A-A线和C-C线的剖视图；其中，为了清楚地显示金属环的结构，图1中未示出硅胶振膜，图1实际为未注胶时的扬声器金属环的结构，而为了更清楚地说明金属环与硅胶振膜的关系，图2-图4示出了硅胶振膜，图2-图4实际为注胶后的扬声器振动系统的结构。
如图所示，本实施例提供的扬声器振动系统包括振膜和结合于振膜下侧的金属环1；振膜为硅胶振膜7；硅胶振膜7与金属环1注塑结合在一起，两者形状相互配合均为环状，例如圆环状、跑道型等等；金属环1优选为不锈钢材质，但不限于不锈钢材质，其包括两部分区域，分别为靠近金属环1外表面的区域形成外部块体2(在图1中为 左斜线阴影)和靠近金属环1内表面的区域形成内部块体3(在图1中为网格)，外部块体2的高度高于内部块体3的高度形成高度差，使外部块体2与内部块体3相接地位置形成台阶面，从金属环1整体结构的角度考虑，两个区域形成的台阶面为环状空间，由于环状空间与振膜模具(图未示出)连通，通过向环状空间注入硅胶，从而将硅胶填充满振膜模具形成硅胶振膜(图1未示出)，硅胶振膜7成型后的高度与外部块体2的高度相持平；其中，环状空间注入的硅胶形成硅胶振膜7的边缘部分，与金属环1连接在一起，使金属环1固定住硅胶振膜7。
金属环1的外部块体2和内部块体3实际为一体成型结构，如图2所示，图中阴影部分为阶梯形结构的金属环1，为了方便表述将金属环1分为外部块体2和内部块体3，从图2中还可以看出，内部块体3(在图2中为右斜线阴影)的高度低于外部块体2(在图2中为左斜线阴影)的高度，两个块体的高度形成高度差，从而使外部块体2与内部块体3相接处形成台阶面，金属环1形成台阶面的目的在于为了定位硅胶振膜7(在图2中为网格阴影)的整体高度，具体地，由于对应台阶面形成的环状空间内注胶，注胶后，胶层(相当于振膜的边缘部分)位于内部块体3之上，所以，胶层与内部块体3结合的高度与外部块体2的高度相同，由于外部块体2为金属材质，不具有弹性，因此，在本实用新型示出的扬声器振动系统的结构中，金属环1与硅胶振膜7结合后的整体高度是固定的，不会被模组外壳压缩变形，其中，外部块体3起到定位高度的作用。
另外，在向台阶面形成的空间内注胶时，外部块体2充当挡墙，注胶后形成的硅胶振膜7的高度和内部块体3的高度之和与外部块体2的高度相同。
需要说明的是，现有金属环的外部块体2和内部块体3高度相同，对内部块体3进行冲压处理，从而外部块体2与内部块体3形成台阶面。
还需要说明的是，硅胶注塑后的厚度公差大于金属件的厚度公差，对于具有高度差的金属环结构，由于外部块体2为金属材质，因此， 可以减小振膜与金属环结合后的公差，从而使振膜与金属环能够和扬声器的其它器件更好的配合。
在向台阶面形成的环状空间注胶时，为了使注胶更均匀，在外部块体2的多个边缘位置分别开设下凹的缺口5，优选地，当金属环1为圆环形时，缺口5均匀地开设在外部块体2上，当金属环1为跑道形(包括四个直立边)时，缺口5分别开设在四个直立边上；缺口5既能起到均衡注塑模具内压力的作用，使得注塑后振膜厚度均衡，又能起到增大金属环1与硅胶振膜7的接触面积的作用，提高固定硅胶振膜7的效果。
缺口5的开口深度小于外部块体2的高度，优选地，缺口5的开口深度等于内部块体3与外部块体3形成的高度差，以便将缺口5与内部块体3连通。
根据图1所示，图3剖面的位置在缺口5处，在图3所示的剖面结构中，缺口5的开口深度为内部块体3(在图3中为右斜线阴影)与外部块体2(在图3中为左斜线阴影)形成的高度差，但缺口5的开口深度也可以小于内部块体3与外部块体2形成的高度差；在向高度差形成的区域注胶后，硅胶振膜7(在图3中为网格阴影)的高度与内部块体3的高度之和刚好等于外部块体2的高度。
需要说明的是，对外部块体2的边缘进行冲切工艺处理，从而形成缺口5。
为了使金属环1更牢固地固定住硅胶振膜7，在金属环1上还设置有注胶孔4，图5为图1的局部放大图，放大了注胶孔4的具体结构，从图3中可以看出，当硅胶振膜7注塑成型时，注胶孔4的开口端形成卡料位卡料位6会勾住硅胶振膜7所对应的凹陷处，防止硅胶振膜7脱出，起到固定的作用。换言之，注胶孔4的区域在注塑后会形成硅胶块，注胶孔4会包住硅胶块，避免硅胶振膜7在水平方向的移动。
上述描述了注胶孔4的形状，下面将对注胶孔4开设的位置进行说明，注胶孔4开设的位置分为以下几种情况：
1)所述注胶孔开设的位置设置在内部块体3上；
2)注胶孔4竖向贯穿金属环1，具体为贯穿外部块体2与内部块体3相接的部分。
无论哪种开设方式，注胶孔4均为内凹的结构，且数量为至少一个。
对于情况，注胶孔4的形状可以为具有卡料位6的任意形状，只要是能够包住注胶孔4的形状就可以，例如注胶孔4的横截面为弧形或方形等形状。
需要说明的是，如果金属环1为圆环形，注胶孔4可设置在两个缺口5之间，如果金属环1为跑道型，注胶孔4则设置在四个转角处(也就是四个直立边形成的角部)，而具体位置同上所述。
从图1中可以看出，图4的剖面位置在注胶孔4处，并且，注胶孔4为前述的第一种情况，从图4中可以看出，外部块体2的高度为硅胶振膜7(在图4中为网格阴影)的高度。
图2-图4分别从普通位置、缺口5和注胶孔4处对金属环1进行剖面，从不同的角度清楚地显示出了金属环1与硅胶振膜7的位置关系。
综上所述，本实用新型提供的扬声器振动系统，通过在金属环内部形成内凹的注胶孔，避免硅胶振膜在水平方向和竖直方向的移动；另外，金属环内、外部块体相接处形成台阶面，在对应台阶面的部分填充硅胶形成硅胶振膜，由于外部块体高于内部块体，且外部块体为不具有弹性的金属材料，因此可以定位硅胶振膜和金属环的整体高度；再者，外部块体边缘设置的缺口可以增加硅胶振膜与金属环的接触面积，能够提高金属环固定硅胶振膜的效果，该缺口还作为注胶口，通过在不同的位置设置多个缺口，可以使硅胶填充的更均匀。
以上所述，仅为本实用新型的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本实用新型的保护范围之内。因此，本实用新型的保护范围应所述以权利要求的保护范围为准。
