Abstract
A camera module includes an optical package, a camera actuator for moving the optical package, a camera subassembly, and one or more resilient members arranged within the camera subassembly to prevent, reduce, or cushion contact between the optical package and other components of the camera. The resilient members may be mounted on the lens carrier of the optical package and configured to come into resistive contact with components of the camera subassembly and/or mounted on components of the camera subassembly and configured to come into resistive contact with the optical package. In either case, the resistive cushioning provided by the resilient members may reduce or prevent contact (and an associated rattling noise associated with the contact) between the optical package and the hard components of the camera subassembly. The resilient members may be configured to cushion, but also allow hard stop contact. In embodiments bumpers (e.g., elastomeric pads) may be used.
