下面参考图1-图9描述根据本发明实施例的防尘网组件100。
如图1-图8所示，根据本发明实施例的防尘网组件100，包括：磁铁1、线圈2、刷头3和防尘网4。
具体而言，磁铁1为长方体形状，磁铁1具有第一磁场。线圈2位于磁铁1的一侧(如图5所示的上侧)，线圈2适于产生第二磁场。刷头3设在线圈2内且与线圈2连接，刷头3的端面超出线圈2的端面，例如，如图6和图7所示，刷头3的上端面超出线圈2的上端面。防尘网4位于线圈2的远离磁铁1的一侧，例如，如图5所示，防尘网4位于线圈2的上侧。
其中，当第二磁场的方向与第一磁场的方向相反时，线圈2朝向防尘网4移动，刷头3适于与防尘网4接触，当第二磁场的方向与第一磁场的方向相同时，线圈2朝向磁铁1移动。由此，可以通过改变第二磁场的方向实现刷头3移动，例如，如图5所示的上下方向的移动。当刷头3与防尘网4接触时，刷头3可以实现从下向上清洗防尘网4，可以使刷头3反复上下运动，实现彻底清洗防尘网4的目的，避免堵孔现象的发生，提升电子设备1000的品质，同时避免人工清洗防尘网4，降低售后费用。
需要说明是，线圈2产生的第二磁场可以由线圈2内通入的电流产生，当线圈2内通入电流且电流沿第一方向流动时，第二磁场的方向与第一磁场方向相反；当线圈2内通入电流且电流沿第二方向流动时，其中第一方向与第二方向相反，第二磁场的方向与第一磁场方向相同。当然，本发明不限于此，线圈2中产生的第二磁场可以由其他磁场感应产生。线圈2内是否产生第二磁场以及第二磁场产生的方向可以由控制软件进行控制并定时清理。
根据本发明实施例的防尘网组件100，通过设置磁铁1，且在磁铁1的一侧设置线圈2，并在线圈2内设置与线圈2连接的刷头3，防尘网4设在线圈2的远离磁铁1的一侧，磁铁1具有第一磁场，线圈2适于产生第二磁场，当第二磁场的方向与第一磁场的方向相反时，线圈2朝向防尘网4移动，刷头3适于与防尘网4接触，当第二磁场的方向与第一磁场的方向相同时，线圈2朝向磁铁1移动。由此，可以通过改变第二磁场的方向实现刷头3移动，当刷头3与防尘网4接触时，刷头3可以实现从下向上清洗防尘网4，可以使刷头3反复上 下运动，实现彻底清洗防尘网4的目的，避免堵孔现象的发生，提升电子设备1000的品质，同时避免人工清洗防尘网4，降低售后费用。
根据本发明的一些实施例，线圈2的中心线a与磁铁1的中心线b重合。由此，当第二磁场的方向与第一磁场的方向相反时，可以快速驱动线圈2朝向防尘网4移动，刷头3适于与防尘网4接触以清洗防尘网4，当第二磁场的方向与第一磁场的方向相同时，线圈2朝向磁铁1移动，且线圈2在移动的过程中沿直线延伸，可以使刷头3准确的对准防尘网4并清扫防尘网4。
进一步地，如图5和图8所示，线圈2的横截面的形状与防尘网4的横截面形状相同且面积相等。由此，可以在线圈2内合理设置刷头3，使刷头3可以清扫到防尘网4的每个角落，避免防尘网4的某些地方存在堵孔的现象，从而避免人工进一步地清洗，提升电子设备1000的品质，降低售后费用。
更进一步地，如图1所示，防尘网4的横截面的形状为长圆形。相应地，如图8所示，线圈2的横截面的形状为长圆形。由于现有的电子设备1000趋向轻薄化发展，将防尘网4设置为长圆形，有利于电子设备1000的轻薄化发展，且长圆形的防尘网4相对比较美观，且占用空间小，提高了电子设备1000的美观性。
需要说明的是，“长圆形”可以定义为：选取圆上位于同一直径上的两点或选取圆上关于圆心对称的两段弧线，沿直线或弧线对圆进行拉伸形成的图形。例如，长圆形可以为如图1、图8所示的长圆形，当然，长圆形也可以形成为椭圆形。
当然，本发明不限于此，防尘网4的横截面的形状还可以为圆形、椭圆形、多边形(例如矩形)等。相应地，线圈2的横截面的形状为于防尘网4的横截面的形状相适配的形状。由此，可以实现刷头3彻底清扫防尘网4的目的，提高防尘网4的洁净度。
在本发明的一些实施例中，如图2所示，线圈2的中心线a与磁铁1的中心线b之间具有预定距离。也就是说，线圈2的中心线a与磁铁1的中心线b间隔开。例如，在图2所示的示例中，在沿磁铁1的长度方向(如图2所示的左右方向)上，线圈2的中心线a偏离磁铁1的中心线b，且线圈2的中心线a向左偏离磁铁1的中心线b。
线圈2位于初始位置时，线圈2的中心线与磁铁1的中心线之间的连线为直线m，直线m与线圈2的中心线a和磁铁1的中心线b均垂直。当第二磁场的方向与第一磁场的方向相反时，线圈2不仅朝向远离磁铁1的方向移动，即朝向防尘网4移动，线圈2还可以沿直线m的方向移动，线圈2的中心线a从位于磁铁1的中心线b的一侧移动到磁铁1的中心线b的另一侧，然后再从磁铁1的中心线b的另一侧移动到磁铁1的中心线b的一侧，往复移动。相应地，刷头3在防尘网4上可以沿直线m的方向往复移动，由此，便于防尘网4的清洗， 避免防尘网4出现堵孔。
例如，在图1和图2所示的示例中，当第二磁场的方向与第一磁场的方向相反时，线圈2不仅可以向上移动，线圈2还可以向右移动，然后再向左移动，实现线圈2的往复移动。相应地，刷头3沿左右方向往复移动，从而实现刷头3对防尘网4的清洗，避免防尘网4堵孔。
进一步地，如图2和图5所示，线圈2的长度小于防尘网4的长度。由此，当线圈2移动时，可以避免线圈2内部分刷头3移动至防尘网4外侧，位于防尘网4外侧的部分刷头3对防尘网4的清洗不起作用，还增加成本，将线圈2的长度设置为小于防尘网4的长度，可以使线圈2内的刷头3始终可以清刷防尘网4，可以节省材料，降低成本。
进一步地，线圈2的宽度等于防尘网4的宽度。由此，在防尘网4的宽度方向上，线圈2内的刷头3可以清洗防尘网4上的灰尘，避免在防尘网4的宽度方向上存在刷头3清理不到的地方，从而保证防尘网4清洗的洁净度。
在本发明的一些实施例中，如图3和图5所示，防尘网4的边缘处设有朝向线圈2延伸的挡板41，挡板41与防尘网4限定出安装空间42，线圈2位于安装空间42内。一方面，挡板41可以起到固定线圈2的作用，另一方面，挡板41可以起到导向作用，线圈2可沿挡板41的内侧壁移动。
进一步地，如图5所示，挡板41为一个，挡板41沿防尘网4的周向方向延伸。由此，可以简化结构及加工工艺，节约生产周期，降低生产成本。更进一步地，挡板41的横截面为环形。也就是说，在防尘网4的外周沿处均具有朝向线圈2延伸的挡板41，由此可以将线圈2牢固的限定在安装空间42内，且更好地为线圈2起到导向作用。
当然，本发明不限于此，挡板41还可以为多个，多个挡板41沿防尘网4的周向方向间隔开。由此，不但可以对线圈2起到一定的固定作用和导向作用，还可以节省材料，降低成本。
在本发明的一些实施例中，如图3和图5所示，挡板41的自由端(如图5所示的下端)设有安装部43，安装部43与磁铁1连接。由此，可以增加防尘网4与磁铁1之间连接的可靠性，从而可以将线圈2固定在防尘网4和磁铁1之间，便于线圈2内的刷头3对防尘网4进行清洗。例如，在图3和图5所示的示例中，位于所述防尘网4的长边上的挡板41的自由端设有安装部43，安装部43与挡板41垂直，安装部43沿防尘网4的长度方向(如图5所示的左右方向)延伸，安装部43与磁铁1的表面平行，安装部43的与磁铁1相对的表面与磁铁1连接。
在本发明的一些实施例中，刷头3为一个，刷头3填满线圈2限定出的腔室。也就是说， 刷头3为一个，且刷头3的横截面的形状与线圈2限定出的腔室的形状相同且面积相同。由此，可以增加刷头3对防尘网4的清洁速度，提高刷头3的清洁效率，节省时间。
当然，本发明不限于此，如图5、图6-图8所示，刷头3为多个，多个刷头3间隔开。由此，便于刷头3的设置，便于简化防尘网组件100的结构，有利于节约生产周期，降低生产成本。
在本发明的一些实施例中，如图5-图8所示，防尘网组件100还包括支架5，支架5套设于线圈2外，支架5可以对线圈2起到固定的作用。如图5所示，支架5的横截面为长圆环形，线圈2固定在支架5内。进一步地，支架5为金属支架5。金属支架5便于线圈2的移动。
进一步地，如图5和图6所示，支架5上设有供线圈2的绕线穿过的避让槽51。线圈2的绕线的两端从避让槽51穿出，可以使支架5的下端面(如图6所示的下端面)与与其连接的部件贴合，避免支架5出现固定部可靠情况，从而保证支架5内的线圈2的移动轨迹的正确性，进而提高防尘网4清洁的可靠性。
更进一步地，如图5和图6所示，避让槽51为两个。由此，绕线的两端分别可以从两个避让槽51穿出，便于绕线的设置。再进一步地，如图5和图6所示，两个避让槽51相对设置，由此，进一步地便于绕线的设置。当然，本发明不限于此，避让槽51还可以为一个，线圈2绕线的两端均可以从该避让槽51穿出。
下面参考图1-图9描述根据本发明实施例的电子设备1000的电声组件200。
如图1-图9所示，根据本发明实施例的电子设备1000的电声组件200，包括上述防尘网组件100和振动组件6。
具体而言，振动组件6位于磁铁1和线圈2之间，振动组件6的横截面形状与磁铁1的横截面形状相同且面积相等，振动组件6的朝向线圈2的端面上设有凹槽61。凹槽61的底壁可以为薄膜，薄膜会振动，薄膜连着一个小小的线圈。
当电声组件为话筒组件时，对着薄膜说话，薄膜会震动，薄膜连着一个小线圈，话筒组件里有一块固定的永磁铁，当薄膜振动时，带动线圈振动，线圈和永磁铁的相对位置改变，这使得穿过线圈的磁场发生变化，磁场变化了会在线圈中产生感应电动势，也就产生了电流。特定的声音有特定的振动，特定的振动产生特定形式的电流。所以话筒就把声音“编码”成了电流的形式。
当电声组件为听筒时，听筒的原理大概是话筒的逆过程，结构也几乎一样。听筒里也有一个薄膜，薄膜连接着一个线圈，同样也有一块永磁铁。特定形式的电流(比如话 筒刚刚“编码”完成的电流)流过听筒的线圈，这样就使得线圈产生的磁场发生变化，于是永磁铁和线圈之间的磁力发生变化，于是永磁铁和线圈的距离会发生变化。这样就带动了薄膜振动，发出声音。
需要说明的是，电声组件不限于听筒或话筒，还可以为其他结构，例如扬声器。麦克风等。还需要说明的是，电声组件200的中永磁铁可以为上述磁铁1，也可以为单独设置的永磁铁。
根据本发明实施例的振动组件6构成以及远离对于本领域普通技术人员而言都是已知的，这里不再详细描述。
根据本发明实施例的电子设备1000的电声组件200，通过设置磁铁1，且在磁铁1的一侧设置线圈2，并在线圈2内设置与线圈2连接的刷头3，防尘网4设在线圈2的远离磁铁1的一侧，磁铁1具有第一磁场，线圈2适于产生第二磁场，当第二磁场的方向与第一磁场的方向相反时，线圈2朝向防尘网4移动，刷头3适于与防尘网4接触，当第二磁场的方向与第一磁场的方向相同时，线圈2朝向磁铁1移动。由此，可以通过改变第二磁场的方向实现刷头3移动，当刷头3与防尘网4接触时，刷头3可以实现从内向外清洗防尘网4，可以使刷头3反复上下运动，实现彻底清洗防尘网4的目的，避免堵孔现象的发生，提升电子设备1000的品质，同时避免人工清洗防尘网4，降低售后费用。
在本发明的一些实施例中，如图5和图2所示，电声组件200还包括限位件7，限位件7位于凹槽61的开口处且与振动组件6连接。限位件7可以对线圈2起到支撑的作用，防止线圈2落入振动组件6的凹槽61内。
进一步地，如图5和图2所示，限位件7覆盖凹槽61的开口。由此，限位件7可以将凹槽61的开口封堵，避免线圈2落入凹槽61内，提高线圈2工作的可靠性。例如，在图5和图2所示的示例中，限位件7的横截面形状与振动组件6的横截面形状相同且面积相等，限位件7完全覆盖凹槽61的开口，由此，可以避免线圈2落入凹槽61内。
更进一步地，如图5所示，限位件7上设有多个间隔开的通孔71。由此，可以使振动组件6内产生的声音通过通孔71穿出到防尘网4的外侧，增强音量。
下面参考图1-图9描述根据本发明一个具体实施例的电子设备1000的电声组件200，值得理解的是，下述描述只是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。以手机为例对本发明所适用的电子设备1000进行介绍。在本发明实施例中，手机可以包括射频电路、存储器、输入单元、无线保真(WiFi，wireless fidelity)模块、显示单元、传感器、音频电路、处理器、投影单元、拍摄单元、电池等部件。
需要说明的是，手机仅为一种电子设备1000的举例，本发明并未特别限定，本发明可 以应用于手机、平板电脑等电子设备1000，本发明对此不做限定。
具体而言，如图1-图9所示，根据本发明实施例的电子设备1000的电声组件200，包括防尘网组件100和振动组件6，防尘网组件100包括磁铁1、线圈2、刷头3、支架5和防尘网4，振动组件6设在磁铁1和线圈2之间。
如图1-图8所示，磁铁1为长方体形状，磁铁1具有第一磁场，线圈2位于磁铁1的一侧(如图5所示的上侧)，线圈2适于产生第二磁场。刷头3设在线圈2内且与线圈2连接，刷头3的上端面超出线圈2的上端面。防尘网4位于线圈2的远离磁铁1的一侧(如图5所示的上侧)。
当第二磁场的方向与第一磁场的方向相反时，线圈2朝向防尘网4移动，刷头3适于与防尘网4接触，当第二磁场的方向与第一磁场的方向相同时，线圈2朝向磁铁1移动。由此，可以通过改变第二磁场的方向实现刷头3移动，例如，如图5所示的上下方向的移动。当刷头3与防尘网4接触时，刷头3可以实现从下向上清洗防尘网4，可以使刷头3反复上下运动，实现彻底清洗防尘网4的目的，避免堵孔现象的发生，提升电子设备1000的品质，降低售后费用。
需要说明是，线圈2产生的第二磁场可以由第二线圈2内通入的电流产生，当线圈2内通入电流且电流沿第一方向流动时，第二磁场的方向与第一磁场方向相反；当线圈2内通入电流且电流沿第二方向流动时，其中第一方向与第二方向相反，第二磁场的方向与第一磁场方向相同。
如图1和图2所示，线圈2的中心线a与磁铁1的中心线b之间具有预定距离。也就是说，线圈2的中心线a与磁铁1的中心线b间隔开。例如，如图2所示，线圈2的中心线a向左偏离磁铁1的中心线b。当第二磁场的方向与第一磁场的方向相反时，线圈2不仅可以向上移动，线圈2还可以向右移动，然后再向左移动，实现线圈2的往复移动。相应地，刷头3沿左右方向往复移动，从而实现刷头3对防尘网4的清洗，避免防尘网4堵孔。
进一步地，如图2和图5所示，线圈2的长度小于防尘网4的长度。由此，当线圈2移动时，可以避免线圈2内部分刷头3移动至防尘网4外侧，位于防尘网4外侧的部分刷头3对防尘网4的清洗不起作用，还增加成本，将线圈2的长度设置为小于防尘网4的长度，可以使线圈2内的刷头3始终可以清刷防尘网4，可以节省材料，降低成本。
进一步地，线圈2的宽度等于防尘网4的宽度。由此，在防尘网4的宽度方向上，线圈2内的刷头3可以清洗防尘网4上的灰尘，避免在防尘网4的宽度方向上存在刷头3清理不到的地方，从而保证防尘网4清洗的洁净度。
如图3和图5所示，防尘网4的边缘处设有朝向线圈2延伸的挡板41，挡板41与防尘 网4限定出安装空间42，线圈2位于安装空间42内。一方面，挡板41可以起到固定线圈2的作用，另一方面，挡板41可以起到导向作用，线圈2可沿挡板41的内侧壁移动。
进一步地，如图5所示，挡板41为一个，挡板41沿防尘网4的周向方向延伸。由此，可以简化结构及加工工艺，节约生产周期，降低生产成本。更进一步地，挡板41的横截面为环形。也就是说，在防尘网4的外周沿处均具有朝向线圈2延伸的挡板41，由此可以将线圈2牢固的限定在安装空间42内，且更好地为线圈2起到导向作用。
如图3和图5所示，位于所述防尘网4的长边上的挡板41的自由端设有安装部43，安装部43与挡板41垂直，安装部43沿防尘网4的长度方向(如图5所示的左右方向)延伸，安装部43与限位件7的表面平行，安装部43的与限位件7相对的表面与限位件连接。
如图5、图6和图8所示，刷头3为多个，多个刷头3间隔开。由此，便于刷头3的设置，便于简化防尘网组件100的结构，有利于节约生产周期，降低生产成本。
如图5-图8所示，支架5套设于线圈2外，支架5可以对线圈2起到固定的作用。如图5所示，支架5的横截面为长圆环形，线圈2固定在支架5内。进一步地，支架5为金属支架5。金属支架5便于线圈2的移动。进一步地，如图5和图6所示，支架5上设有供线圈2的绕线穿过的避让槽51，避让槽51为两个且两个避让槽51相对设置。由此，绕线的两端分别可以从两个避让槽51穿出，便于绕线的设置。
如图1-图8所示，振动组件6的横截面形状与磁铁1的横截面形状相同且面积相等，振动组件6的朝向线圈2的端面上设有凹槽61。凹槽61的底壁可以为薄膜，薄膜会振动，薄膜连着一个小小的线圈。
当电声组件为话筒组件时，对着薄膜说话，薄膜会震动，薄膜连着一个小线圈，话筒组件里有一块固定的永磁铁，当薄膜振动时，带动线圈振动，线圈和永磁铁的相对位置改变，这使得穿过线圈的磁场发生变化，磁场变化了会在线圈中产生感应电动势，也就产生了电流。特定的声音有特定的振动，特定的振动产生特定形式的电流。所以话筒就把声音“编码”成了电流的形式。
当电声组件为听筒时，听筒的原理大概是话筒的逆过程，结构也几乎一样。听筒里也有一个薄膜，薄膜连接着一个线圈，同样也有一块永磁铁。特定形式的电流(比如话筒刚刚“编码”完成的电流)流过听筒的线圈，这样就使得线圈产生的磁场发生变化，于是永磁铁和线圈之间的磁力发生变化，于是永磁铁和线圈的距离会发生变化。这样就带动了薄膜振动，发出声音。
需要说明的是，电声组件不限于听筒或话筒，还可以为其他结构，例如扬声器。麦克风等。还需要说明的是，电声组件200的中永磁铁可以为上述磁铁1，也可以为单独 设置的永磁铁。
如图3和图5所示，电声组件200还包括限位件7，限位件7覆盖凹槽61的开口，限位件7上设有多个间隔开的通孔71。限位件7可以对线圈2起到支撑的作用，防止线圈2落入振动组件6的凹槽61内，振动组件6内产生的声音通过通孔71穿出到防尘网4的外侧，增强音量。
