DRIVE ACTUATOR AND ELECTRONIC DEVICE

WIPO Patent Application WO/2023/231296

A1

Provided is a drive actuator, comprising a housing, a vibration part and a braking part; the housing is provided with an accommodating cavity; the vibration part comprises an outer housing and a vibration piece, the outer housing is fixed within the accommodating cavity, a vibration cavity is formed within the outer housing, and the vibration piece is arranged within the vibration cavity in a vibrating manner; the braking part comprises a drive piece fixed within the accommodating cavity and a braking assembly connected to an output end of the drive piece; the drive piece drives the braking assembly to be away from or close to the vibration part, so that the braking assembly and the vibration piece are arranged at an interval or the braking assembly and the vibration piece are in elastic abutment. The technical solution of the present application significantly expands the asymmetry of anisotropic vibrations, and discretely exhibits asymmetric vibrations within a short time. Vibrations close to actually generated asymmetric vibration forces are produced, such that a clear force sensation towards a certain direction is discretely exhibited within a short time, the direction of the force sensation depending on the abutment direction of the braking assembly and the vibration piece, so that there is no longer a limitation with respect to the holding manner.
