    • The present invention discloses a camera module having an auto-focus apparatus including: a piezoelectric actuator for generating a force for moving a driven member; a rod connected to the piezoelectric actuator and transmitting the force of the piezoelectric actuator to the driven member; a lens barrel having at least one lens; and a connecting member for coupling the rod and the lens barrel together by a magnetic force. The connecting member has a rod guide groove corresponding to the rod and the rod is inserted and coupled to the rod guide groove in a movable manner. Since the lens barrel as a driven member is magnetically coupled to the rod which is adapted to move by the piezoelectric actuator, it is possible to easily assure the tilting performance of lens while securing and maintaining a preload. In addition, the overall size of the camera module can be reduced.
    • 本发明公开了一种具有自动对焦装置的相机模块,包括:压电致动器,用于产生用于移动从动部件的力; 连接到所述压电致动器并将所述压电致动器的力传递到所述从动构件的杆; 具有至少一个透镜的镜筒; 以及用于通过磁力将杆和镜筒联接在一起的连接构件。 连接构件具有对应于杆的杆引导槽,并且杆以可移动的方式插入并联接到杆引导槽。 由于作为从动构件的镜筒被磁耦合到适于由压电致动器移动的杆,所以可以在确保并保持预载的同时容易地确保透镜的倾斜性能。 此外,可以减小相机模块的总体尺寸。

    • A piezoelectric motor for generating an elliptic motion by adding a longitudinal vibration to a bending-direction vibration is provided. The piezoelectric motor includes a piezoelectric member which generates a first vibration mode and a second vibration mode simultaneously by an applied power and a frictional member of which a portion is insertedly attached into a concave portion indentedly formed on one side of the piezoelectric member, wherein the frictional member is in an elliptic motion by the vibration generated by the piezoelectric member, so that an influence of the attachment of the frictional member to a resonance frequency can be minimized. Accordingly, a driving efficiency of the piezoelectric motor can be improved. In addition, attachment strength of the frictional member can be improved.
    • 提供一种用于通过向弯曲方向振动添加纵向振动来产生椭圆运动的压电电动机。 压电电动机包括:压电元件,其通过施加的动力同时产生第一振动模式和第二振动模式;以及摩擦部件,其部分插入地插入到压电元件的一侧上的凹部中,其中, 摩擦构件通过由压电构件产生的振动来进行椭圆运动,从而可以使摩擦构件的附着对谐振频率的影响最小化。 因此,能够提高压电马达的驱动效率。 此外,可以提高摩擦构件的附着强度。
