Abstract
Various embodiments include a damper arrangement that may be used to dampen motions of a dynamic component. In some embodiments, the damper arrangement may be used in a camera module that includes a stationary component and a dynamic component. For instance, the dynamic component may hold a lens such that the lens moves together with the dynamic component. In various examples, the damper arrangement may include an interface member that extends from the stationary component or the dynamic component to at least partially into a viscoelastic material within a pocket configured in the stationary component, the dynamic component, or both. The interface member may be configured to traverse within the viscoelastic material to dampen motion of the dynamic component, for example, during operation of a lens actuator to move the dynamic component along an optical axis of the lens.
