A lens module includes a case, one and more lens units positioned in the case and having at least one lens, a carrying member, a piezoelectric driving unit, and at least a fixing member. The carrying member is connected to the lens unit such that the lens unit is movable forward and backward. The piezoelectric driving unit is mounted in the case for transferring a driving force to the carrying member so as to carry the lens unit to move. By using this configuration, the front and rear lens units may conduct the auto focus function and the zoom function respectively, thereby reducing a stroke of the lens, and reducing the size of the lens driving unit. Accordingly, the lens module may be manufactured in a small size so that it may be inserted into a cellular phone.

A device for assembling a lens assembly includes a base, a barrel having a bottom, a universal joint disposed between the base and the bottom of the barrel, a push rod, and a resilient member. The universal joint is configured for allowing the barrel to tilt in any direction. The push rod is configured for depressing the lenses received to the barrel to form a lens barrel. The resilient member is disposed between the base and the bottom of the barrel. In process of assembling lenses, when the push rod presses the lenses received in the barrel, the lens assembly can hold the axis of the lenses in coaxial alignment under the cooperation of the universal joint and exert a uniformity force on a surface of the lenses. The lens assembly can eliminate the risk of breakage of the lenses and accurately position the lenses.

A lens holder coupling a lens to an actuator is disclosed. The actuator includes a vibrator and a driving rod coupled to the vibrator along a vibration direction of the vibrator. The lens holder includes a lens carrier, a transmission member, a guiding member, and a fixing member. The lens carrier is configured for accommodating the lens. The transmission member connected to the lens carrier defines a groove having a transmission axis parallel to an optical axis of the lens receiving the driving rod. The guiding member connected to the lens carrier defines a hole receiving a guide rod substantially parallel to the optical axis of the lens. The fixing member includes a main body and an elastic sheet, the main body being fixed to the transmission member, the elastic sheet extending from the main body and covering the groove and configured for elastically contacting the driving rod.
