Description

扬声器及其装配方法和振动机构以及音响装置 技术领域
本发明涉及声音领域，特别涉及一扬声器及其装配方法和振动机构以及音响装置。
背景技术
图1至图3示出了现有技术的一扬声器100P，其包括一框架10P、一磁回系统20P、一鼓纸30P、一悬边40P以及一音圈50P，其中所述磁回系统20P被安装于所述框架10P的低端部11P，其中所述悬边40P的外侧和内侧分别延伸以被连接于所述框架10P的高端部12P和所述鼓纸30P的外侧边缘31P，以保持所述鼓纸30P于所述框架10P的所述高端部12P，其中所述音圈50P的音圈低端51P和所述磁回系统20P互相磁性交流地连接，所述音圈50P的音圈高端52P被连接于所述鼓纸30P的中心位置。所述扬声器100P具有一中心轴线101P，其中所述鼓纸30P的中心轴线、所述悬边40P的中心轴线和所述音圈50P的中心轴线均与所述扬声器100P的所述中心轴线101P重合，也即，所述鼓纸30P以所述扬声器100P的所述中心轴线101P为中心对称轴而呈中心对称，所述悬边40P以所述扬声器100P的所述中心轴线101P为中心对称轴而呈中心对称，所述音圈50P以所述扬声器100P的所述中心轴线101P为中心对称轴而呈中心对称。在所述扬声器响应音频信号的输入时，所述磁回系统20P和所述音圈50P互相作用以带动所述鼓纸30P沿着所述扬声器100P的中心轴线101P做往复运动，如此所述鼓纸30P能够鼓动空气而产生声波，其中所述悬边40P用于限制所述鼓纸30P的冲程而保证所述鼓纸30P的运动方向。
图4和图5示出了现有技术的一音响装置，其包括一箱体200P和被安装于所述箱体200P的所述扬声器100P。在设计现有的所述音响装置时，为了保证所述音响装置的美观性，所述扬声器100P被安装于所述箱体200P的前障板201P的中心线上，这样所述扬声器100P的所述中心轴线101P到所述前障板201P的 两侧边缘的距离完全相等，如此会导致所述音响装置在所述箱体200P的边缘出现绕射现象而影响所述音响装置的音质。为了减少甚至避免绕射问题，现有技术的所述音响装置均采用了对所述箱体200P的形状进行设计的方式，例如将所述箱体200P设计呈非对称状而避免所述扬声器100P的所述中心轴线101P到所述箱体200P的两侧边缘的距离相等，这种方式不仅要求设计师具有专业的声学知识，而且导致所述箱体200P无法被设计成规整的形状。具体地，图6A示出了所述箱体200P的所述前障板201P的左侧边缘反射的左侧反射声波1000P的辐射状态，图6B示出了所述箱体200P的所述前障板201P的右侧边缘反射的右侧反射声波2000P的辐射状态，附图6C示出了所述左侧反射声波1000P和所述右侧反射声波2000P相遇后形成的复合声波3000P的辐射状态，此时，所述左侧辐射声波1000P的波峰出现的时间和所述右侧辐射声波2000P的波峰出现的时间相同，以至于所述复合声波3000P会突然叠加而严重影响所述音响装置的音质。

参考说明书附图之附图7A至图9，依本发明的一较佳实施例的一扬声器100在接下来的描述中被揭露和被阐述，其中所述扬声器100包括一框架10、一磁回系统20、一悬边30、一鼓纸40以及一音圈50。
所述框架10具有一框架低端11和对应于所述框架低端11的一框架高端12。
所述磁回系统20具有一磁隙21和连通于所述磁隙21的一磁隙开口22，其中所述磁回系统20被安装于所述框架10的所述框架低端11，并且所述磁回系统20的所述磁隙开口22朝向所述框架10的所述框架高端12。
所述鼓纸40具有一鼓纸外侧41，所述悬边30具有一悬边内侧31和对应于所述悬边内侧31的一悬边外侧32，其中所述悬边30的所述悬边内侧31向内延伸以被连接于所述鼓纸40的所述鼓纸外侧41，相应地，所述悬边30的所述悬边外侧32向外延伸以被连接于所述框架10的所述框架高端12，以藉由所述悬边30保持所述鼓纸40于所述框架10的所述框架高端12。
所述音圈50具有一音圈低端51和对应于所述音圈低端51的一音圈高端52，其中所述音圈50的所述音圈低端51经所述磁回系统20的所述磁隙开口22延伸至和被可活动地保持于所述磁回系统20的所述磁隙21，并且所述音圈50的所述音圈低端51和所述磁回系统20互相磁性交流地连接，相应地，所述音圈50的所述音圈高端52延伸至和被连接于所述鼓纸40，以界定所述鼓纸40的一被驱动位置42，并且所述鼓纸40的所述被驱动位置42偏离所述扬声器100的中心轴线101，和所述扬声器100的活动轴线102穿过所述鼓纸40的所述被驱动位置42。换言之，所述扬声器100的所述活动轴线102偏离所述中心轴线101。
当所述扬声器100响应音频信号的输入时，所述磁回系统20和所述音圈50的所述音圈低端51互相磁性地交流，以允许所述磁回系统20通过所述音圈50于所述鼓纸40的所述被驱动位置42驱动所述鼓纸40沿着所述扬声器100的所述活动轴线102做往复运动而鼓动空气以向外辐射声波，其中所述悬边30用于限制所述鼓纸40的冲程和保证所述鼓纸40沿着所述扬声器100的所述活动轴线102做往复运动。
优选地，所述扬声器100的所述活动轴线102穿过所述鼓纸40的重心位置，如此当所述音圈50于所述鼓纸40的所述被驱动位置42驱动所述鼓纸40沿着所述扬声器100的所述活动轴线102做往复运动时，所述鼓纸40能够被保持水平而避免出现偏斜，如此能够保证所述扬声器100的音质。
参考附图7A至图9，在本发明的所述扬声器100中，所述鼓纸40具有一近轴位置43和对应于所述近轴位置43的一远轴位置44，其中所述鼓纸40的所述近轴位置43是指所述鼓纸40的所述鼓纸外侧41的边缘的最接近所述扬声器100的所述活动轴线102的位置，相应地，所述鼓纸40的所述远轴位置44是指所述鼓纸40的所述鼓纸外侧41的边缘最远离所述扬声器100的所述活动轴线102的位置。在本发明的所述扬声器100中，所述鼓纸40的厚度尺寸自所述近轴位置43向所述远轴位置44逐渐变薄，以使所述鼓纸40的重心位置靠近所述近轴位置43而远离所述远轴位置44，如此所述扬声器100的所述活动轴线102能够穿过所述鼓纸40的重心位置，从而在所述音圈50驱动所述鼓纸40沿着所述扬声器100的所述活动轴线102做往复运动时，所述鼓纸40能够保持水平而避免出现倾斜，以保证所述扬声器100的音质。
进一步地，参考附图7A至图9，所述框架10包括一低端框架13和被安装于所述低端框架13的一高端框架14，其中所述低端框架13形成所述框架10的所述框架低端11，所述磁回系统20被安装于所述低端框架13而使所述磁回系统20被保持于所述框架低端11，相应地，所述高端框架14形成所述框架10的所述框架高端12，所述悬边30的所述悬边外侧32被连接于所述高端框架14，而使所述鼓纸40被保持于所述框架高端12。
更具体地，参考附图7B和图8，所述低端框架13进一步包括一磁回安装环131、一接合环132以及延伸于所述磁回安装环131和所述接合环132之间的多个互相间隔的连接臂133，其中所述低端框架13的所述磁回安装环131以环绕 于所述磁回系统20的外侧的方式被安装于所述磁回系统20，如此使得所述磁回系统20被安装于所述低端框架13。所述磁回安装环131的中心轴线和所述接合环132的中心轴线互相偏离而不重合，如此使得被安装于所述磁回安装环131的所述磁回系统20的中心轴线和所述接合环132的中心轴线互相偏离而不重合。
相应地，所述高端框架14包括一保持环141和自所述保持环141向下延伸的至少两接合臂142，其中所述悬边30的所述悬边外侧32被连接于所述高端框架14的所述保持环141，以允许所述保持环141环绕于所述鼓纸40的四周。所述高端框架14的所述接合臂142被安装于所述低端框架13的所述接合环132，并且所述高端框架14的所述保持环141的中心轴线和所述低端框架13的所述接合环132的中心轴线重合，如此使得所述磁回系统20的中心轴线和所述保持环141的中心轴线互相偏离而不重合。
需要说明的是，在本发明的所述扬声器100中，所述高端框架14的所述保持环141的中心轴线和所述低端框架13的所述接合环132的中心轴线决定了所述扬声器100的所述中心轴线101，并且所述扬声器100的所述中心轴线101、所述高端框架14的所述保持环141的中心轴线以及所述低端框架13的所述接合环132的中心轴线互相重合，相应地，所述磁回系统20的中心轴线决定过了所述扬声器100的所述活动轴线102，并且所述扬声器100的所述活动轴线102和所述磁回系统20的中心轴线互相重合。在本发明的所述扬声器100中，所述磁回系统20的中心轴线偏离所述高端框架14的所述保持环141的中心轴线和所述低端框架13的所述接合环132的中心轴线，从而所述扬声器100的所述活动轴线102偏离所述中心轴线101。
在附图7A至图9示出的所述扬声器100的这个较佳示例中，所述鼓纸40可以通过注塑的方式形成，如此能够使得所述鼓纸40的厚度尺寸自所述近轴位置43向所述远轴位置44逐渐变薄。所述悬边30的形成方式在本发明的所述扬声器100中不受限制。例如，在本发明的所述扬声器100的一个具体示例中，所述悬边30被预制，其中所述悬边30的所述悬边内侧31可以通过胶水等黏着物质被粘接于所述鼓纸40的所述鼓纸外侧41，相应地，所述悬边30的所述悬边外侧32可以通过胶水等黏着物质被粘接于所述高端框架14的所述保持环141。在本发明的所述扬声器100的另一个具体示例中，所述悬边30一体地形成于所述鼓纸40和所述高端框架14的所述保持环141之间，从而所述悬边30的所述悬 边内侧31在所述悬边30成型的过程中一体地连接于所述鼓纸40的所述鼓纸外侧41，和所述悬边30的所述悬边外侧32在所述悬边30成型的过程中一体地连接于所述高端框架14的所述保持环141。
继续参考附图7A至图9，所述扬声器100进一步包括一稳轴器60，所述稳轴器60具有一稳轴内侧61和对应于所述稳轴内侧61的一稳轴外侧62，其中所述稳轴器60的所述稳轴内侧61延伸至和被连接于所述音圈50，所述稳轴器60的所述稳轴外侧62延伸至和被连接于所述框架10，其中当所述磁回系统20驱动所述音圈50沿着所述扬声器100的所述活动轴线102做往复运动时，所述音圈50能够带动所述稳轴器60产生形变，以藉由所述稳轴器60限制所述音圈50的往复运动方向而避免所述音圈50的运动方向偏离所述扬声器100的所述活动轴线102。
进一步地，所述低端框架13包括一接合台134，其中所述接合台134自所述接合环132向内延伸，所述稳轴器60的所述稳轴外侧62被连接于所述低端框架13的所述接合台134。
值得一提的是，所述稳轴器60的形状在本发明的所述扬声器100中不受限制，例如在附图7A至图9示出的所述扬声器100的这个具体示例中，所述稳轴器60可以被实施为类似于悬边的形状，即所述稳轴器60的截面形状可以是“U”形，或者所述稳轴器60的截面形状可以是“S”形，或者所述稳轴器60的截面形状可以是波浪形，而在本发明的所述扬声器100的其他具体示例中，所述稳轴器60可以是弹波。
继续参考附图7A至图9，所述扬声器100进一步包括一防尘帽70，其中所述防尘帽70被安装于所述音圈50的所述音圈高端52，以用于封闭所述音圈50的高端开口，从而防止灰尘进入所述音圈50的内部。所述防尘帽70的形状在本发明的所述扬声器100中不受限制，其可以是一个半球体结构，也可以是一个平板结构。
值得一提的是，所述鼓纸40的形状在本发明的所述扬声器100中不受限制，例如在附图7A至图9示出的所述扬声器100的这个具体示例中，所述鼓纸40可以是喇叭状结构，而在附图10和图11示出的所述扬声器100的另一个具体示例中，所述鼓纸40可以是平板状结构。
附图13示出了所述扬声器100的一个变形示例，与附图7A至图9示出的所 述扬声器100不同的是，在附图12示出的所述扬声器100的这个变形示例中，所述鼓纸40在各个位置的厚度尺寸一致，其中所述悬边30的厚度尺寸自所述悬边30的对应于所述鼓纸40的所述近轴位置43的位置向所述悬边30的对应于所述鼓纸40的所述远轴位置44的位置方向逐渐变薄，如此使得所述悬边30和所述鼓纸40形成的一个振动机构103的重心位置靠近所述鼓纸40的所述近轴位置43而远离所述远轴位置44，如此所述扬声器100的所述活动轴线102能够穿过所述振动机构103的中心位置，从而在所述音圈50驱动所述鼓纸40沿着所述扬声器100的所述活动轴线102做往复运动时，所述鼓纸40能够保持水平而避免倾斜，以保证所述扬声器100的音质。
值得一提的是，在附图12示出的所述扬声器100的这个具体示例中，所述鼓纸40可以是注塑工艺制成的，也可以是将一个平板状结构弯折并粘接自由端部后制成的。
附图13示出了所述扬声器100的另一个变形示例，与附图7A至图9示出的所述扬声器100不同的是，在附图12示出的所述扬声器100的这个变形示例中，所述鼓纸40在各个位置的厚度尺寸一致，其中用于粘接所述悬边30的所述悬边内侧31和所述鼓纸40的向所述鼓纸外侧41的胶水层80的厚度尺寸自所述鼓纸40的所述近轴位置43向所述远轴位置44逐渐变薄，如此使得所述悬边30、所述鼓纸40和所述胶水层80形成的所述振动机构103的重心位置靠近所述鼓纸40的所述近轴位置43而远离所述远轴位置44，如此所述扬声器100的所述活动轴线102能够穿过所述振动机构103的中心位置，从而在所述音圈50驱动所述鼓纸40沿着所述扬声器100的所述活动轴线102做往复运动时，所述鼓纸40能够保持水平而避免倾斜，以保证所述扬声器100的音质。
值得一提的是，在附图13示出的所述扬声器100的这个具体示例中，所述鼓纸40可以是注塑工艺制成的，也可以是将一个平板状结构弯折并粘接自由端部后制成的，所述悬边30需要被预制。
依本发明的另一个方面，本发明进一步提供所述扬声器100的装配方法，其中所述装配方法包括如下步骤：
(a)以所述磁回系统20的中心轴线偏离所述低端框架13的所述接合环132的中心轴线的方式安装所述磁回系统20于所述低端框架13的所述磁回安装环131；
(b)允许所述悬边30的所述悬边内侧31和所述悬边外侧32分别被连接于所述鼓纸40的所述鼓纸外侧41和所述高端框架14的所述保持环141；以及
(c)以所述保持环141的中心轴线和所述接合环132的中心轴线重合的方式安装所述高端框架14于所述低端框架13，以使被连接于所述鼓纸40的所述被驱动位置42的所述音圈50朝向所述磁回系统20方向延伸而与所述磁回系统20磁性交流地连接，并且所述鼓纸40的所述被驱动位置42偏离所述扬声器100的所述中心轴线101，以装配所述扬声器100。
在本发明的所述扬声器100的一个具体示例中，所述步骤(b)进一步包括步骤：
注塑所述鼓纸40，以使所述鼓纸40的厚度尺寸自所述鼓纸40的所述近轴位置43向所述远轴位置44逐渐变薄；和
于所述鼓纸40和所述高端框架14的所述保持环141之间一体地形成所述悬边30。
在本发明的所述扬声器100的另一个具体示例中，所述步骤(b)进一步包括步骤：于所述鼓纸40和所述高端框架14的所述保持环141之间一体地形成所述悬边30，其中所述悬边30的厚度尺寸自所述悬边30的对应于所述鼓纸40的所述近轴位置43的位置向所述悬边30的对应于所述鼓纸40的所述远轴位置44的位置逐渐变薄。

在本发明的所述音响装置中，所述扬声器100的所述鼓纸40的所述被驱动位置42偏离所述扬声器100的中心轴线，如此即便是所述扬声器100被安装于所述箱体200的所述前障板201的中间位置，所述箱体200的位于所述扬声器100的所述活动轴线102两侧的部分也不会出现等距的情况，如此能够有效地减少甚至避免绕射问题而保证所述音响装置的音质。并且，所述音响装置在不需要对所述箱体200进行专门设计的前提下即可减少甚至避免绕射问题，从而使得不熟悉甚至不了解声学专业知识的设计师也能够轻松地设计出具有良好音质的所述音响装置。
