  • Publication number: 20200096782
    Abstract: A damper arrangement may be used in a camera module that includes a first (e.g., stationary) and a second (e.g., dynamic) component. The second component may hold a lens such that the lens moves together with the second component. The damper arrangement may include an interface member that extends from the first or the second component to at least partially into a viscoelastic material within a volumetric space configured in the first component, the second component, or both. The interface member may include a mounting portion having a thickness and a viscoelastic material section, having a different thickness, that interacts with viscoelastic material to dampen motion of the second component, for example, during operation of a lens actuator to move the second component along an optical axis of the lens. The interface member may be a two-piece interface member, such as a pin soldered into a hole in a plate, for example.
