  • Publication number: 20240106305
    Abstract: A camera module for a portable electronic device includes an actuator assembly with at least one coil segment. The coil segment includes a dielectric substrate with two surfaces. Over each surface is formed a trace that follows a path defining a multi-turn coil. The coils of each side of the dielectric are conductively coupled together to define a single inductor/coil. The two-layer coil segment can be encapsulated as a component suitable for pick-and-place and/or SMT manufacturing. In many constructions, the actuator assembly includes a stack of coil segments, coupled together in series or parallel.

  • Publication number: 20240107166
    Abstract: A camera including a camera enclosure; an optomechanical assembly fixedly coupled to the camera enclosure; a sensor assembly having an image sensor and an electronic component mounted to a substrate that is movably coupled to the camera enclosure; a voice coil motor having a base coupled to the optomechanical assembly and a carrier coupled to the sensor assembly that is operable to cause a displacement of the sensor assembly relative to the optomechanical assembly; and a displacement limiter coupled to the base or the carrier to limit an unintended displacement of the sensor assembly.

  • Publication number: 20240107165
    Abstract: A camera including a camera enclosure; a fixed optics portion having a prism fixedly coupled to the camera enclosure by a voice coil motor base; a moving sensor portion having an image sensor package coupled to the camera enclosure by a voice coil motor carrier that extends around the image sensor package and is operable to cause a displacement of the image sensor package relative to the fixed optics portion; and a damper coupled to the fixed optics portion or the moving sensor portion to absorb an impact between the fixed optics portion and the moving sensor portion.

  • Patent number: 11800209
    Abstract: A camera may include an image sensor attached with a substrate configured to move relative to one or more lenses of the camera in one or more directions. The camera may include one or more actuators to control movement of the image sensor, which may include at least one magnet and at least one corresponding coil. The magnet of the actuators may be attached with the substrate, outside a perimeter of the substrate or on the substrate but close to the perimeter of the substrate. The magnet may cause the adjacent portion of the substrate to become cantilevered with only partial support. The camera may include a frame structure having one or more raised regions towards the magnet to reduce a stress on the cantilevered portion of the substrate, e.g., during a drop or shock event.

  • Publication number: 20230004063
    Abstract: Various embodiments include a camera with a ball bearing suspension arrangement that suspends one or more tiltable structures. In some embodiments, the camera may include an optical element, an image sensor, an actuator arrangement, and the ball bearing suspension arrangement. The actuator arrangement may include a tilt actuator configured to tilt one or more tiltable structures about a tilt axis. The ball bearing arrangement may suspend the tiltable structure(s) from a base structure and allow motion of the tiltable structure(s) enabled by the tilt actuator. In various embodiments, the ball bearing suspension arrangement may include a ball bearing that is positioned at a different height, along the tilt axis, than one or more other ball bearings of the ball bearing suspension arrangement.
