AI Technical Summary

Technical Problem

Conventional vibration devices struggle to generate discrete, clear, and well-defined anisotropic vibrations, often requiring continuous and limited frequency stimulation, which limits their practical applications.

Method used

A drive exciter with a bracket, guide structure, vibration unit, damping portion, and locking portion that switches between states to intermittently engage and disengage, allowing for discrete anisotropic vibrations by controlling the frequency and direction of contact between the vibrating and damping parts.

Benefits of technology

The drive exciter enables clear and discrete anisotropic vibrations in a short time, providing a realistic sense of force direction without reliance on gripping methods, and expands the asymmetry of vibration sensations.

Abstract

The present invention discloses a driving exciter and an electronic device including a bracket including a fixture and a guide structure connected to the fixture, a vibrating part movably connected to the guide structure and provided with a vibrator capable of vibrating, a braking part connected to the fixture and provided toward the vibrating part, and a locking part including a driver connected to the fixture and a locking material connected to an output end of the driver. The driving exciter has a first state in which the locking material is in contact with the vibrating part and a second state in which the locking material is detached from the vibrating part. In the second state, the vibrating part moves toward the braking part and is in contact with the braking part. The technical solution of the present application can expand the asymmetry of anisotropic vibration and generate vibration close to the actually generated asymmetric vibration force, so as to discretely present a clear sense of force in a certain direction in a short time. Since the direction of this sense of force depends on the contact direction between the braking part and the vibrator, it is not limited to the gripping method.
