如图6所示，马达还包括电路板5，所述电路板5设置于所述下盖板4与所述电致振动片3之间，所述电路板5与所述电致振动片3电连接，以使所述电致振动片3的第一表面和第二表面被施加电压，使得所述电致振动片3驱动所述质量块2移动。可通过对电致振动片3施加极性交替变换的电压，使得电致振动片3驱动所述质量块2往复移动，从而产生振感。

马达还包括振动片支架，所述振动片支架环设于所述电致振动片3，所述电致振动片3通过所述振动片支架与所述下盖板4固定连接。振动片支架可采用价格低廉的绝缘材料制作，以节省电致振动片3的用量，降低马达的成本。
在本申请一个实施例中，所述电致振动片3为离子传导振动片；
当施加于所述离子传导振动片的电压为第一电压时，所述离子传导振动片驱动所述质量块2沿第一方向移动；
当施加于所述离子传导振动片的电压为第二电压时，所述离子传导振动片驱动所述质量块2沿第二方向移动；
其中，所述第一电压和所述第二电压极性相反，所述第一方向与所述第二方向反向。即所述第一方向与所述第二方向互为反方向，通过向离子传导振动片交替施加极性相反的电压，可使得离子传导振动片驱动所述质量块2沿第一方向和第二方向交替移动，从而产生振感。
如图10所示，所述离子传导振动片包括依次叠设的第一电极层101、离子交换树脂层102以及第二电极层103，所述离子交换树脂层102内具有聚合物电解质。离子传导振动片可采用离子交换聚合金属材料(ion-exchange polymer metal composite，IPMC)制作。IPMC材料是一种新型电致动功能材料，以离子交换树脂层(如氟碳聚合物等)为基体，在基体表面镀贵金属(如铂、银等)，以形成电极层，即第一电极层101和第二电极层103。离子交换树脂层102包括聚合物电解质，聚合物电解质中含有阳离子和阴离子，图10中阳离子和阴离子的位置及数量仅为示意，不代表实际情况。如图11、图12所示，当对IPMC在厚度方向施加电压时，聚合物电解质中的水合阳离子会移动到阴极侧，引起IPMC的阳极面和阴极面溶胀的差异，从而产生变形，向 阳极面弯曲，这样，可通过控制IPMC的通电电压或者电流来控制IPMC弯曲程度，使得IPMC在横向方向上产生位移。
IPMC材料为一种新型驱动材料，具有驱动质轻、产生位移形变大、驱动电压低等优点。采用IPMC的优势明显，例如，IPMC为非磁性材料，不会产生磁干扰；IPMC变形产生的位移和速度与IPMC的厚度成比例地减小，IPMC变形产生的力与IPMC的厚度的立方成比例地增大。因此，可根据实际情况来设置IPMC的厚度，以达到所需的IPMC变形产生的位移、速度和力度。
通过对电致振动片3离子传导振动片施加电压，聚合物电解质中的阳离子移动到阴极侧，引起电致振动片3离子传导振动片正面和背面溶胀的差异，这种差异可使得电致振动片3离子传导振动片发生形变，交替改变施加在电致振动片3离子传导振动片上的电压方向，可使得电致振动片3离子传导振动片的形变方向交替改变，从而带动质量块2交替移动，产生振感。振动幅度可为0.1毫米到10毫米，振动幅度可以通过设置电致振动片3离子传导振动片的厚度和调节通过电致振动片3离子传导振动片的电流大小进行控制。
图7所示为电致振动片3中通过正方向电流时，电致振动片3中阳离子分布示意图，其中，阳离子移动到电致振动片3的阴极侧(即图7中电致振动片3的第二表面32)，电致振动片3向上移动，并带动质量块2向上移动，图7中箭头所示方向为电致振动片3的移动方向。
图8所示为电致振动片3中通过负方向电流时，电致振动片3中阳离子分布示意图，其中，阳离子移动到电致振动片3的阴极侧(即图8中电致振动片3的第一表面31)，电致振动片3向下移动，并带动质量块2向下移动，图8中箭头所示方向为电致振动片3的移动方向。通过对离子传导振动片施加电压，离子传导振动片的聚合物电解质中的阳离子移动到阴极侧，引起正面和背面溶胀的差异，使得离子传导振动片产生形变。当对离子传导振动片施加交流电时，离子传导振动片会带动质量块2往复振动，从而产生振感。
在需要监控电子设备散热的场景下，通过电子设备内的温度传感器对温度进行监控，达到需散热的温度点后，电子设备向电致振动片3输出约为0.05W的低功耗电信号，通电的电致振动片3便可往复振动，从而带动质量块2周边振动而发声，从而提醒用户电子设备的温度较高，需要散热，以避 免设备损坏。
在需要自动散热的场景下，通过电子设备内的温度传感器对温度进行监控，达到需散热的温度点后，电子设备向电致振动片3输出约为0.05W的低功耗电信号，通电的电致振动片3便可往复振动，从而带动质量块2振动，从而带动空气流动进行散热。
进一步的，当施加于所述离子传导振动片的电压为第一电压时，所述离子传导振动片驱动所述质量块2沿第一方向移动第一距离；
当施加于所述离子传导振动片的电压为第三电压时，所述离子传导振动片驱动所述质量块2沿第一方向移动第二距离；
其中，所述第一电压和所述第三电压极性相同，且所述第三电压大于所述第一电压，所述第一距离与所述第二距离不相同。
其中，所述第一电压和所述第三电压极性相同，且所述第三电压大于所述第一电压，所述第一距离与所述第二距离不相同，例如，第二距离可大于第一距离。当需要质量块2移动较大距离时，可通过向离子传导振动片施加较大电压来驱动质量块2移动较大距离；当需要质量块2移动较小距离时，可通过向离子传导振动片施加较大电压来驱动质量块2移动较小距离。施加于离子传导振动片的电压大小与质量块2的移动距离之间具有对应关系，在确定质量块2需要移动的距离的情况下，可根据该对应关系来确定施加于离子传导振动片的电压大小。
进一步的，当施加于所述离子传导振动片的电压为第一电压时，所述离子传导振动片以第一速率驱动所述质量块2沿第一方向移动；
当施加于所述离子传导振动片的电压为第三电压时，所述离子传导振动片以第二速率驱动所述质量块2沿第一方向移动；
其中，所述第一电压和所述第三电压极性相同，且所述第三电压大于所述第一电压，所述第一速率与所述第二速率不相同。例如，第二速率可小于第一速率。当需要质量块2移动速率较大时，可通过向离子传导振动片施加较大电压来驱动质量块2以较大速率进行移动；当需要质量块2移动速率较小时，可通过向离子传导振动片施加较小电压来驱动质量块2以较小速率进行移动。施加于离子传导振动片的电压大小与质量块2的移动速率之间具有 对应关系，在确定质量块2需要移动的速率的情况下，可根据该对应关系来确定施加于离子传导振动片的电压大小。
本申请实施例中，还提供一种电子设备，该电子设备包括上述实施例中的马达。由于上述马达的结构中没有磁钢和线圈，不会对马达周围的电路和器件产生磁场干扰，净化了马达周围的电路和器件的工作环境；同时，上述马达结构简单，便于自动化生产，同时，由于上述马达占用空间小，可更加满足电子设备薄型化的需求。
