Vibration assembly and touch exciter with same

Abstract

The invention relates to the technical field of tactile feedback, in particular to a vibration assembly and a tactile exciter with the vibration assembly, and the vibration assembly comprises an elastic piece which comprises a middle fixing part, elastic arms which are connected with the middle fixing part along the same straight line direction and extend towards opposite directions, and end fixing parts which are arranged at the free ends of the two elastic arms, the end part fixing part is used for being connected with a shell; the magnetic cover assembly comprises a magnetic cover body, the magnetic cover body is connected with the middle fixing part, and the magnetic cover body is provided with an opening cavity in the direction away from the middle fixing part; the magnetic steel assembly is fixed in the open cavity of the magnetic cover assembly and comprises main magnetic steel arranged in the center of the open cavity; wherein the magnetic cover main body is formed by laminating a plurality of cold-rolled magnetic conductive plates. According to the invention, the magnetic cover assembly is arranged, and the magnetic cover main body is formed by laminating the plurality of cold-rolled magnetic conductive plates, so that the quality of the vibration assembly is improved, the use amount of magnetic steel is small, the manufacturing cost is reduced, and the processing technology is simplified.

Description

technical field [0001] The present invention relates to the technical field of haptic feedback, and in particular, to a vibration component and a haptic exciter having the vibration component. Background technique [0002] The tactile exciter refers to the principle of electromagnetic induction, which generates an alternating magnetic field by passing alternating current in the coil to drive the vibration component in the magnetic field to reciprocate, so as to feedback the vibration to the operator when the operator performs a touch operation; the vibration component Most of them are composed of magnetic steel and shrapnel, and how to adjust the effect of vibration has become a key issue; [0003] In the related art, in order to achieve ultra-low frequency vibration, large-sized magnets and pole pieces are often used to increase the quality of the vibration components, but the magnets are rare earth materials, and the large-sized magnets result in higher cost output; For t...

[0003]In related technologies, in order to achieve ultra-low frequency vibration, large-sized magnets and pole pieces are often used to increase the quality of vibration components, but magnets are rare earth Material, large-size magnetic steel results in higher cost output; for this reason, in the field of tactile actuators, the shape and size of shrapnel are often adjusted to change the frequency, amplitude and acceleration of vibration, resulting in more and more complex structures of shrapnel. The processing technology is also becoming more and more complicated;
