ACTUATOR MODULE WITH IMPROVED DAMAGE RESISTANCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240040320 titled 'ACTUATOR MODULE WITH IMPROVED DAMAGE RESISTANCE

Simplified Explanation

The abstract describes an actuator module that consists of a base plate, a voice coil, and a magnet assembly. The magnet assembly includes a base layer and sidewalls that form a cup, with a center magnet mounted inside. The actuator module also includes a rigid frame with four stubs and a plurality of springs that suspend the magnet assembly relative to the frame and base plate.

  • The actuator module includes a base plate, voice coil, and magnet assembly.
  • The magnet assembly has a cup-shaped structure with a center magnet.
  • The module has a rigid frame with four stubs.
  • Multiple springs suspend the magnet assembly from the frame and base plate.

Potential Applications:

  • This actuator module can be used in various mechanical systems that require precise and controlled movements, such as robotics, automation, and positioning systems.
  • It can be employed in devices that require vibration or motion control, such as speakers, haptic feedback devices, or actuators for virtual reality systems.

Problems Solved:

  • The actuator module provides a stable and controlled movement by suspending the magnet assembly with springs, reducing unwanted vibrations and oscillations.
  • The cup-shaped magnet assembly ensures efficient magnetic coupling with the voice coil, resulting in precise and accurate motion.

Benefits:

  • The actuator module offers improved precision and accuracy in motion control applications.
  • It provides a stable and reliable mechanism for controlled movements, reducing the chances of errors or malfunctions.
  • The cup-shaped magnet assembly enhances the magnetic coupling, resulting in efficient energy transfer and improved performance.



Original Abstract Submitted

an actuator module includes a base plate extending in a plane, a voice coil connected to the base plate, and a magnet assembly that includes a back side facing the base plate and a front side facing away from the base plate. the magnet assembly includes a base layer and sidewalls defining a cup and an inner element including a center magnet mounted within the cup. the sidewalls include a first and second pair of sidewalls. the actuator module includes a rigid frame attached to the base plate, the rigid frame including four stubs. the actuator module also includes a plurality of springs suspending the magnet assembly relative to the frame and base plate, the plurality of springs including a first spring attached to the frame at a first pair of the four stubs and a second spring attached to the frame at a second pair of the four stubs
