Abstract
The present application discloses a portable electronic device. The device includes a case; a camera lens fixed to the case; a sound generator attached to the case for producing sounds; and a central process unit and a circuit system for providing controlling current to the camera lens. The camera lens includes a side wall and a lens holder moveable relative to the side wall. The lens holder is driven to a predetermined position farther away from the case than an initial position, when the sound generator is producing sounds. The present application further provides a method for eliminating noise by applying controlling current to the lens holder to move the lens holder to a position farther away from the case for avoiding collision between the case and the lens holder.
