摘要： A piezoelectric driving module for lens, which defines a photographic optical axis and includes a housing, a driven object (e.g., a lens module), a piezo member, and a rubbing element. The piezo member and the rubbing element are provided in the housing and located on two lateral sides of the driven object respectively. The piezo member drives the driven object by friction so that the driven object can be moved along the photographic optical axis until focused. Meanwhile, a predetermined frictional force is generated between the rubbing element and the driven object to reduce a gravity-induced speed difference between forward and backward movements of the driven object along the photographic optical axis.

摘要： An anti-shake device for use in an optical system comprises a biaxial rotating element and a electromagnetic driving module. The biaxial rotating element is made by grooving a thin resilient plate to form a special multiple-frame structure. The biaxial rotating element, when driven by the electromagnetic driving module, makes limited pivotal movement about two axes so as to provide shake compensation. The electromagnetic driving module, composed of a plurality of permanent magnets and a plurality of coils, is supported and positioned by an inner support frame and an outer support frame, both of which have uniquely designed structures. The resultant anti-shake device is structurally simple, easy to assemble, compact in size, and relatively low-cost.

摘要： An electromagnetic lens driving device includes a casing, a lens module, a positioning structure, and an electromagnetic driving module. The lens module is provided in a receiving space defined in the casing. The positioning structure, which is connected between the lens module and the casing, is configured to limit the lens module within the receiving space and generate a frictional force. The electromagnetic driving module is provided in the receiving space and corresponds in position to the lens module. When supplied with electricity, the electromagnetic driving module generates a magnetic force that drives the lens module to move along a central axis. Once the electricity is cut off, the lens module is fixed in position and prevented from moving freely by the frictional force of the positioning structure; hence, the electromagnetic lens driving features economical use of electricity.

摘要： An axially actuating device having an elastic joining portion is provided, which is used for carrying an object and actuating the object to move axially, and comprises a fixed portion, a moving portion, and a joining member. The joining member is used to combine the fixed portion with the moving portion, such that the fixed portion and the moving portion are axially coupled with each other. Moreover, the fixed portion and the moving portion are respectively a fixed magnet and a coil, such that when a current is applied to the moving portion, the moving portion generates a relative displacement with respect to the fixed portion according to the current, so as to provide an axial displacement. Meanwhile, the moving energy is generated due to the repulsive interaction of the magnetic field, and thus a shock proofing efficacy is also provided.
