Technical Problem
但是，音圈马达在通电过程中会发热，不利于模组温度平衡，导致摄像头模组的散热性能差，此外，通过控制磁场实现镜头的对焦，还会对其他电子元件产生电磁干扰
Benefits of technology
[0039]如上所述，本申请提供的摄像头模组及智能终端，摄像头模组包括镜头组件、推动组件和温度控制件，其中至少部分镜头组件用于活动设于智能终端上，推动组件与镜头组件的镜头本体连接；温度控制件具有发热部，发热部与推动组件接触，推动组件内具有膨胀材料，膨胀材料能够根据发热部的温度膨胀或收缩，以用于通过推动组件带动镜头本体移动。通过设置温度控制件，温度控制件上具有发热部，利用发热部的温度变化，作用于膨胀材料，利用热胀冷缩的物理特性，使膨胀材料膨胀或者收缩，进而带动镜头本体进行对焦。避免使用传统的音圈马达，有助于减少部分零部件的发热，提高摄像头模组的散热性能；此外，通过物理方式（膨胀材料的膨胀或收缩）而非磁场来控制镜头本体的移动，可以显著降低对其他电子元件的电磁干扰，保持智能终端内部其他敏感电子元件的稳定性和性能。
