具体实施方式
为更进一步阐述本发明为达到预定目的所采取的技术手段及功效，以下结合附图及较佳实施例，对本发明的具体实施方式详细说明。
请参照图1与图2，本发明实施例提供一种应用于键盘开关的驱动块驱动单臂式导通发声机构，包括一平衡架1、由平衡架1触发动作的一驱动块2、及由驱动块2触发导通与发声的一导通发声组件3，其中，该导通发声组件3包括一弹性体33、及至少一导通部，该弹性体33具有朝导通部上方延伸的一导通发声弹臂331，该导通发声弹臂331由驱动块2触发动作。当平衡架1被向下按压时，由平衡架1带动驱动块2下移，并由下移的驱动块2带动弹性体33的导通发声弹臂331下移，下移一段行程后，导通发声弹臂331与导通部之间产生导通信号，实现导通功能；接着，导通发声弹臂331发生弹动敲击驱动块2和/或其他部件产生声音，实现发声功能。当释放对平衡架1的按压时，平衡架1对驱动块2的作用力消失，则驱动块2对导通发声弹臂331的作用力消失，因此，导通发声弹臂331由自身的弹性恢复 力上移复位，导通信号消失，实现断开功能。
本实施例驱动块驱动单臂式导通发声机构应用于键盘开关中，每次按压在实现开关导通功能的同时，还实现了发声功能，而且各部件动作准确度高，可提高导通与发声灵敏度，寿命长。同时，由弹性体33上的单根导通发声弹臂331即可实现导通与发声功能，使得实现导通与发声功能的整个部件体积减小，则占用空间小，利于实现键盘开关的薄型化。
在本实施例中，导通发声弹臂331与导通部相结合，可以组成多种不同的导通组件，例如：
(1)机械式导通组件；
(2)对光导通组件；
(3)磁导通组件；
(4)霍尔导通组件。
下面以导通发声弹臂331与导通部组成机械式导通组件为例进行详细说明，具体的，如图5所示，所述导通发声组件3包括两个导通部，分别为第一导通部31与第二导通部32，该第一导通部31与弹性体33接触，实现电连接，则弹性体33与第一导通部31相结合相当于动片；该导通发声弹臂331延伸至第二导通部32上方，则第二导通部32相当于静片。
具体的，所述弹性体33为扭簧33'，扭簧33'的材质为铜材质，则在第一导通部31与扭簧33'接触时，实现第一导通部31与扭簧33'两者的电连接。优选的，所述扭簧33'的材质为磷铜，磷铜具有弹性大、通电量大、电阻小、灵敏度高、寿命长的特性，将其作为扭簧33'，可明显提高导通动作与发声动作的灵敏度。
向下按压平衡架1时，平衡架1带动驱动块2下移，并由下移的驱动块2带动导通发声弹臂331与第二导通部32接触，从而由弹性体33(扭簧33')实现第一导通部31与第二导通部32的电性导通，即实现导通功能，如图10所示；当释放对平衡架1的按压时，导通发声弹臂331由自身的弹性恢复力上移复位，导通发声弹臂331与第二导通部32分离，则实现断开功能，如图9所示。
为了便于导通发声弹臂331能够更好的与第二导通部32接触导通，可以在第 二导通部32上设置一静触点321，如图9与图10所示，在导通状态时，导通发声弹臂331与静触点321接触，实现电性导通。
对于导通发声组件3的安装方式，如图3、图4与图6所示，本实施例导通发声组件3安装于一安装座4上，在该安装座4下端面形成有供导通发声弹臂331弹动的一活动槽41，在该活动槽41内向下凸设有供扭簧33'的主体安装的一安装轴42，对扭簧33'的主体进行限位，在该安装座4上开设有供导通发声弹臂331端部露出的一开口43，以便于供驱动块2带动下移。在驱动块2带动导通发声弹臂331下移时，导通发声弹臂331在活动槽41内下移动。
在驱动块2带动导通发声弹臂331下移时，为了使导通发声弹臂331能脱离开驱动块2发生弹动，如图4所示，本实施例在所述活动槽41靠近导通发声弹臂331的内壁上形成有一导引斜面44，在驱动块2带动导通发声弹臂331下移时，同时由导引斜面44导引导通发声弹臂331向一侧移动，使得导通发声弹臂331下移到一段行程后，导通发声弹臂331与第二导通部32接触导通，接着导通发声弹臂331顺利脱离开驱动块2对导通发声弹臂331向下的作用面，从而发生弹动，敲击驱动块2、安装座4或其他部件发出声音。
在本实施例中，为了对导通发声弹臂331进行更准确的按压，如图3所示，本实施例在所述驱动块2上形成有作用于导通发声弹臂331端部的一按压块21，在驱动块2下移时，由按压块21直接作用于导通发声弹臂331，实现更准确的按压。
同时，为了使按压块21能够带动导通发声弹臂331一直下移，直到导通发声弹臂331能够与第二导通部32接触导通，如图3所示，本实施例在所述按压块21一侧边上形成有对导通发声弹臂331端部进行限位的一限位钩211。在按压块21下移时，由限位钩211对导通发声弹臂331端部进行限位，使得按压块21能够带动导通发声弹臂331一直下移，直到导通发声弹臂331与第二导通部32接触导通后，再脱离开按压块21发生弹动，实现敲击发声。
为了使导通发声弹臂331脱离开按压块21后能够顺利发生弹动，如图3所示，本实施例在所述按压块21上形成有一倾斜面22，为导通发声弹臂331脱离开按压块21及发生弹动提供让位空间。
在本实施例中，如图7所示，所述第一导通部31与第二导通部32均为导电片，该导电片设置于活动槽41下端且扣合于安装座4上，且该导电片电连接于PCB板上。
对于驱动块2的安装，如图2与图3所示，所述驱动块2围设于安装座4外围，且该驱动块2一端转动设置于安装座4上，所述按压块21设置于驱动块2另一端上。具体的，如图3所示，驱动块2一端形成有两个转动中心孔20，在安装座4上设置有插入转动中心孔20内的两个转轴40。平衡架1作用于驱动块2另一端，使得驱动块2另一端下摆，即以转轴40为中心点向下摆动，使得按压块21随着下移而作用于导通发声弹臂331；在平衡架1受到的作用力消失后，在导通发声弹臂331的弹性恢复力作用下，带动驱动块2另一端上摆，即以转轴40为中心点向上摆动复位。
为了更准确的作用于驱动块2，如图2与图3所示，本实施例在所述驱动块2另一端延伸设置有一按压连动块23，在所述平衡架1上凸设有位于按压连动块23上方的一凸块14，具体的，所述平衡架1包括一平衡杆A 11、一平衡杆B 12、及连接于平衡杆A 11与平衡杆B 12之间的一复位拉簧13，其中，所述凸块14设置于平衡杆A 11或平衡杆B 12上。在平衡架1受力下移时，由凸块14直接作用于驱动块2的按压连动块23，带动驱动块2向下摆动。
当将本实施例驱动块驱动单臂式导通发声机构应用于键盘开关中时，平衡杆A 11与平衡杆B 12转动式安装于基座10上，而且安装座4也设置于基座10上，如图1至图3所示；同时，平衡杆A 11与平衡杆B 12转动式连接于键帽30上，如图8所示。在按压的过程中，平衡架1起到按压平衡作用，利于提高整个键盘开关的平稳性。当然，安装座4还可以直接设置于PCB板上。在向下按压键帽30时，即可带动平衡杆A 11与平衡杆B 12向下摆动。
作为本实施例的另一种实施方式，当导通发声弹臂331与导通部相结合组成对光导通组件时，导通部由光发射管与光接收管组成，并在导通发声弹臂331上设置挡光片。驱动块2带动导通发声弹臂331上的挡光片以导通或阻断光发射管与光接收管之间的光信号通路，来实现开关的导通与断开功能。具体工作原理，可以参照 以下现有技术：申请号201510964805.2，专利名称：模组式光电开关键盘按钮。
作为本实施例的另一种实施方式，当导通发声弹臂331与导通部相结合组成磁导通组件时，导通部为磁感应器，并在导通发声弹臂331上设置磁铁。由驱动块2带动导通发声弹臂331来控制磁铁与磁感应器之间的距离，来实现开关的导通与断开功能。具体工作原理，可以参照以下现有技术：申请号：201510049623.2，专利名称：一种按键及键盘。
作为本实施例的另一种实施方式，当导通发声弹臂331与导通部相结合组成霍尔导通组件时，导通部为霍尔元件，并在导通发声弹臂331上设置磁铁。由驱动块2带动导通发声弹臂331来控制磁铁与霍尔元件之间的距离，来实现开关的导通与断开功能。具体工作原理，可以参照以下现有技术：申请号：201520868417.X，专利名称：一种键盘开关组件。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故采用与本发明上述实施例相同或近似的技术特征，而得到的其他结构，均在本发明的保护范围之内。
