Vibration actuator with weight for high strength and vibration characteristics
The patent application (Publication Number: US20240009701A1) describes a vibration actuator with a unique design to enhance vibration along a specific axis. The actuator includes a casing with a cylindrical shape, a coil inside the casing, and a mover that vibrates along the axis of the casing. The mover consists of a mover body and a weight fixed to it, with a protrusion on the mover body and a recess on the weight, ensuring secure fixation by inserting the protrusion into the recess.
Furthermore, the patent details additional features such as the inclusion of a pole piece and a magnet in the mover body, a specific design where the diameter of the weight's recess is larger than its central shaft, and the use of a bottomed cylinder structure for the weight. The design also incorporates a pillar integrated with the bottomed cylinder, ribs for structural support, and multiple planes with different inclinations on the rib's side surface. These features collectively contribute to a novel vibration actuator design that aims to improve performance and efficiency in various applications requiring controlled vibration along a specific axis.
