Description

Actuators and Electronics

technical field

The invention relates to the technical field of vibration devices, in particular to an exciter and electronic equipment using the exciter.

Background technique

Traditional vibrating devices produce the illusion of force "as if facing a certain direction" by continuously creating asymmetrical vibrations. Such vibrations are also called anisotropic vibrations.

There are currently two ways to realize this sense of force: one is to input an asymmetrical signal to a linear resonator and use human senses to generate an illusion. In principle, this method can only produce a continuous sense of directional force, and cannot achieve discrete vibration output. At the same time, the equivalent force felt in this way is small, and asymmetrical signals will also produce redundant vibrations, so it is difficult to obtain a clear sense of direction. The other is to create a strong sense of force by quickly braking the linear resonator. This method can generate vibrations with large asymmetry, and has the characteristics of a small proportion of redundant vibrations and a separate and clear sense of force. However, this method needs to be composed of a vibrating part and a braking part independently, and the vibrating part or the braking part is constantly moved to switch between the energy storage and braking states, which makes it unable to operate continuously at high speed, and the device structure is complicated.

However, this type of device only realizes the vibration in the linear direction, and cannot produce the sense of force in the rotating direction.

The two impact forces coincide with the line connecting the centroids of the first rotating part 22 and the second rotating part 32, so that the casing 1 is subjected to two forces of the same magnitude and opposite directions, thereby achieving the effect of motion shock cancellation. In another state, that is, when the first rotating part 22 and the second rotating part 32 rotate clockwise and collide with the second side wall 13 and the second partition 15, the first rotating part 22 and the second rotating part 32 are opposite to the casing. The impact force of 1 is equal to the parallel force arms, so as to achieve the effect of pure clockwise rotation.

The lines connecting the centroids of the third rotating part 42 and the fourth rotating part 52 coincide, so that the housing 1 is subjected to two forces of the same magnitude and opposite directions, thereby achieving the effect of offsetting motion impact.
