Abstract
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.
