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

This abstract first appeared for US patent application 18484234 titled 'ACTUATOR MODULE WITH IMPROVED DAMAGE RESISTANCE

Simplified Explanation

The actuator module described in the patent application 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 module also includes a rigid frame attached to the base plate, 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 consists of a base layer, sidewalls, and an inner element with a center magnet.
  • The module has a rigid frame attached to the base plate, with four stubs.
  • A plurality of springs suspend the magnet assembly relative to the frame and base plate.

Potential applications of this technology:

  • Actuator modules like this can be used in various electronic devices that require precise and controlled movements, such as robotics, automation systems, and medical equipment.
  • It can be utilized in audio devices like speakers and headphones to provide accurate and responsive sound reproduction.
  • This technology can be integrated into virtual reality and augmented reality systems to enhance the user experience by providing realistic haptic feedback.

Problems solved by this technology:

  • The actuator module allows for precise and controlled movements, addressing the need for accurate positioning in various applications.
  • The suspension of the magnet assembly using springs helps to minimize vibrations and unwanted noise, improving the overall performance of the device.
  • The design of the magnet assembly and cup structure ensures efficient magnetic coupling and enhances the force generated by the actuator module.

Benefits of this technology:

  • The actuator module provides precise and controlled movements, allowing for accurate positioning and improved performance in various applications.
  • The use of springs to suspend the magnet assembly helps to reduce vibrations and unwanted noise, resulting in a smoother and quieter operation.
  • The efficient magnetic coupling and enhanced force generation contribute to the overall effectiveness and reliability of the actuator module.


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
