下面将在具体实施例中对本实用新型提出的线性振动马达100的具体结 构进行说明，并以线性振动马达100水平放置为例进行介绍：
在本实用新型实施例中，该线性振动马达100包括壳体10、定子组件20、振子组件30以及导磁块40，所述壳体10具有容纳腔10a；所述定子组件20包括铁芯22和绕设于所述铁芯22的线圈21，所述线圈21和所述铁芯22收容于所述容纳腔10a内，并与所述壳体10固定；所述振子组件30通过弹性件悬置于所述容纳腔10a内，所述振子组件30设有磁性件31，所述磁性件31收容于所述容纳腔10a内，并与所述线圈21相对设置，以在所述线圈21的驱使下带动所述振子组件30振动；所述导磁块40收容于所述容纳腔10a内，所述导磁块40以用于所述磁性件31磁性配合，所述导磁块40和所述铁芯22相对设置于所述振子组件30的两侧。
其中，定义振子组件30的振动方向为水平左右方向。线圈21和铁芯22的数量均为两个，一线圈21套设于一铁芯22，该磁性件31包括两个边磁和中心磁铁，两个边磁连接于中心磁铁的左右两侧，两边磁磁极相同，且与中心磁铁磁极相反，两个线圈21相邻两边与中心磁体相对，两个线圈21远离的两边分别与两边磁相对，两线圈21电流方向相反，如此当线圈21通电后，便可向边磁施加水平向左(或向右)的作用力，同时向中心磁铁施加水平向左(或向右)的作用力，从而驱使磁性件31在左右方向上发生振动。
此外，该壳体10包括上壳11、中壳12以及底壳13，该上壳11和底壳13连接于中壳12的相对两侧以围合形成容纳腔10a，以便于进行各个部件的前期组装和后期的维修装配。而该该导磁块40可以为金属材质制成，以与磁性件31具有磁性配合，可以理解的是，当该线圈21和铁芯22固定于底壳13时，而该导磁块40即可以直接固定于上壳11朝向底壳13的表面，也可以借助其他结构连接于振子组件30靠近上壳11的一侧，具体可由本领域技术人员进行选择。
该定子组件20还包括电路板23，线圈21的下端固定在电路板23上，电路板23固定在容纳腔10a的底壁上。也就是说，线圈21是通过电路板23固定在壳体10上的。这样，线圈21便可以预先与电路板23进行配装固定，之后连同电路板23一起装配至容纳腔10a内，实现定子组件20与壳体10的固定。如此，便可以使定子组件20的装配更加简单。并且，由于线圈21是固定在电路板23上的，线圈21与电路板23之间的走线更加方便，可以避免容 纳腔10a内较长走线的出现，避免对其他内部结构的装配和运行造成影响，从而保证内部结构运行的稳定性，提高产品的可靠性。实际应用时，电路板23可以采用柔性电路板23。线圈21与电路板23的固定，可通过例如胶接、焊接等方式实现。电路板23与壳体10的固定，可通过例如胶接、焊接等方式实现。
本实用新型技术方案的线性振动马达100运行时，振子组件30的磁性件31在定子组件20的通电后的线圈21驱使下进行振动，而通过将线圈21绕设于铁芯22进行设置，以减少磁性件31的磁场扩散外漏，使穿过线圈21的有效磁感线更加密集，从而提升定子组件20对振子组件30的驱动能力，同时通过将导磁块40和铁芯22相对设置于振子组件30的两侧，以使导磁块40对磁性件31之间磁性配合的吸附力和铁芯22对磁性件31的磁性吸附力平衡，以使得振子组件30的振动过程中稳定保持悬浮的状态，避免振子组件30在振动的过程中朝向铁芯22的方向晃动，以提高振子组件30的振动时的稳定性，进而使得线性振动马达100具有更高的振动稳定性，提升了线性振动马达100可靠性及使用寿命。
在本申请的一实施例中，所述线性振动马达100还包括支撑架50，所述支撑架50与所述壳体10可拆卸连接，并位于所述磁性件31背对所述铁芯22的一侧，所述导磁块40与所述支撑架50连接。其中，该支撑架50可拆卸连接于壳体10处，以便于支撑架50前期安装和后期维修，同时该支撑架50以用于承载导磁块40，从而以保证导磁块40位于容纳腔10a内的稳定性，进而以保证导磁块40对磁性件31之间的磁性配合，以进一步保证振子组件30的振动时的稳定性。
进一步地，所述支撑架50背离所述磁性件31的一侧凹设形成限位槽511，所述导磁块40嵌设固定于所述限位槽511内。其中，通过在支撑架50形成限位槽511，以便于导磁块40的定位安装，同时对安装后的导磁块40起到了抵接限位的作用，此外，当该导磁块40嵌设于限位槽511内后，该导磁块40可以通过焊接、铆接、粘接等方式固定于限位槽511内，以进一步提高导磁块40安装后的稳定性。
更进一步地，所述壳体10的相对两侧均开设有卡槽121，所述支撑架50包括限位部51和两安装部52，所述限位部51背离所述磁性件31的一侧形成 有所述限位槽511，两所述安装部52连接于所述限位部51的相对两侧，一所述安装部52卡接于一所述卡槽121内，以使所述限位部51悬置于所述磁性件31背对所述铁芯22的一侧。可以理解的是，该限位部51和两安装部52可以为一体结构，如此以保证支撑架50整体的结构强度，当然限位部51和两安装部52也可以通过卡接等方式进行固定，以便于后期的维修更换。而该两安装部52可以通过卡接的方式分别卡接于壳体10的相对两侧的卡槽121处，安装和拆卸较为方便，提高了装配效率。而该限位部51背离磁性件31的一侧凹设形成限位槽511，以便于导磁块40的安装。
在本申请的一实施例中，所述振子组件30还包括质量块32和两阻尼块33，所述质量块32设于所述容纳腔10a内，所述磁性件31与所述质量块32连接，以使所述磁性件31带动所述质量块32于所述容纳腔10a内进行振动；所述支撑架50与所述质量块32在振动方向上的两侧分别夹设形成限位空间，一所述阻尼块33设于一所述限位空间内，以分别与所述支撑架50和所述质量块32弹性抵接。其中，由于配置有质量块32，从而使得振子组件30的整体质量得以增加，从而使振子组件30的振动性能得以提升。同时在支撑架50和质量块32在振动方向上的两侧分别夹设形成限位空间，并且将两阻尼块33设于限位空间内，以分别与振子组件30和支撑架50弹性抵接，如此该阻尼块33在振子组件30的振动过程中与支撑架50发生挤压作用，直接反作用于振子组件30，从而提高对振子组件30的缓冲和支撑，进而使得线性振动马达100具有更高的振动稳定性，提升了线性振动马达100可靠性及使用寿命。可以理解的是，阻尼块33可以为泡棉、硅胶等弹性材质制成。
进一步地，所述质量块32朝设有贯穿的安装腔321，所述磁性件31和两所述阻尼块33均嵌设于所述安装腔321内；所述支撑架50沿振动方向的两端具有抵接面512，一所述阻尼块33支撑在一所述抵接面512和所述质量块32于所述安装腔321的腔壁之间，另一所述阻尼块33支撑在另一所述抵接面512和所述质量块32于所述安装腔321的腔壁之间。其中，该磁性件31可以穿过安装腔321的开口后间隙配合固定于安装腔321内，而两阻尼块33可以穿过安装腔321的开口放置于磁性件31的上方，而支撑架50固定于壳体10后并至少部分位于两阻尼块33之间，如此以使得支撑架50与质量块32的安装腔321的腔壁之间形成限位空间，从而该磁性件31和质量块32水平振动 时，会使阻尼块33朝向支撑架50的方向压制，如此以达到对振子组件30提高缓冲作用的效果。当然，该质量块32朝向定子组件20的表面也可以开设有连通安装腔321的通孔，以使得线圈21和磁性件31之间的磁性配合更加便利高效。此外，该支撑架50的两抵接面512可以呈平面设置，不仅便于支撑架50的压铸成型，有利于降低加工成本，而且还便于对阻尼块33的抵接固定，使的阻尼块33缓冲过程中的稳定性更强，从而保证振子组件30振动时的稳定性，提高线性振动马达100的可靠性。
更进一步地，所述振子组件30还包括导磁板60，所述导磁板60连接于所述质量块32朝向所述支撑架50的表面，并朝向所述安装腔321内凹设形成抵接部61，所述抵接部61开设有限位通孔611，所述抵接部61压制所述磁性件31固定于所述安装腔321内，并使两所述阻尼块33限位于所述限位通孔611内。其中，该导磁板60可以贴设于质量块32朝向支撑架50的表面，即贴设于质量块32开设有安装腔321的表面，并且该导磁板60还朝向安装腔321内凹设形成抵接部61，该抵接部61以用于抵接压制磁性件31固定于安装腔321内，以保证磁性件31固定于安装腔321的稳定性。而该抵接部61开设有限位通孔611，如此当抵接部61***安装腔321内后，两阻尼块33可以部分穿过限位通孔611并限位于限位通孔611，从而以进一步提高对阻尼块33的限位作用，提高阻尼块33安装后的稳定性，进一步提高线性振动马达100的可靠性。此外，该阻尼块33包括第一定位部331分别连接于第一定位部331的相对两侧的第二定位部332，如此通过两个第二定位部332嵌设于避让通孔内，以进一步提高阻尼块33安装后的稳定性，而第一定位部331则可以与支撑架50和质量块32的安装腔321的内壁面弹性抵接，进而保证对振子组件30的抵接缓冲的效果。
在本申请的一实施例中，所述弹性件为两弹片70，两所述弹片70收容于所述容纳腔10a内，并分别支撑于所述质量块32沿振动方向上的两侧和所述壳体10之间。可以理解的是，两弹片70可以对质量块32在左右方向上的振动进行缓冲和支撑，从而提升振子组件30振动过程中的稳定性，提升振子组件30的振动性能。
