VIBRATING ACTUATOR AND ELECTRONIC DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17860006 titled 'VIBRATING ACTUATOR AND ELECTRONIC DEVICE

Simplified Explanation

The abstract describes a vibrating actuator that consists of a contact body and a vibrating body. The vibrating body has an energy conversion element and an elastic body that moves relative to the contact body due to vibration. The contact body includes a base part, a thin plate part, a support part, and a friction member. The friction member, which has a higher density than the thin plate part, is separate from the support part and in contact with the elastic body. The weight ratio of the thin plate part to the total weight of the friction member and the support part is between 0.5 and 1.5.

  • The vibrating actuator includes a contact body and a vibrating body with an energy conversion element.
  • The contact body consists of a base part, a thin plate part, a support part, and a friction member.
  • The thin plate part extends from the base part towards the center axis of the base part.
  • The support part is located at the end of the thin plate part.
  • The friction member, separate from the support part, is in contact with the elastic body.
  • The density of the friction member is higher than the density of the thin plate part.
  • The weight ratio of the thin plate part to the total weight of the friction member and the support part is between 0.5 and 1.5.

Potential Applications

  • Haptic feedback devices in smartphones and gaming controllers.
  • Vibration-based actuators in wearable devices and smartwatches.
  • Tactile feedback systems in virtual reality and augmented reality applications.

Problems Solved

  • Provides a simplified and efficient design for vibrating actuators.
  • Enhances the performance and reliability of haptic feedback systems.
  • Improves the user experience by delivering precise and realistic vibrations.

Benefits

  • Increased durability and longevity of vibrating actuators.
  • Enhanced energy conversion efficiency.
  • Improved accuracy and precision in haptic feedback systems.


Original Abstract Submitted

A vibrating actuator includes a contact body and a vibrating body that vibrates, has an energy conversion element, and has an elastic body in contact with the contact body to move relative to each other from the vibration. The contact body has a base part, a thin plate part, a support part, and a friction member. The thin plate part extends from the base part toward an annular center axis of the base part and the support part is disposed at an end of the thin plate part. The friction member is disposed to the support part as a member separate from the support part and in contact with the elastic body. Density of the friction member is higher than density of the thin plate part. A weight ratio of the thin plate part to a total weight of the friction member and the support part is 0.5 to 1.5.
