A directionally focusing tactile feedback interface

Abstract

A directional focusing tactile feedback interface comprises an upper panel, a vibration block and a lower panel, wherein the upper panel is located above the lower panel, the upper panel and the lowerpanel are parallel to each other, a certain distance is kept between the upper panel and the lower panel, and the upper panel and the lower panel are rectangular thin plates; one or more touch areasare distributed on the upper panel, and the thickness of the touch areas is smaller than that of the non-touch areas. Driving elements are arranged on the lower panel, are distributed around the lowerpanel or at specific positions on the upper surface and the lower surface of the lower panel, and vibrate after voltage signals are applied to the driving elements; the upper end surface of the vibration block is connected with the upper panel, and the lower end surface of the vibration block is connected with the lower panel; the number of the vibration blocks below each touch area is one or more. According to the directional focusing tactile feedback interface, the cost problem caused by the fact that each touch area needs a vibration element is solved, the problems of uneven vibration andhigh energy consumption caused by the fact that one or two piezoelectric elements vibrate on the edge of the panel are also solved, and the use effect is good.

Description

Technical field [0001] The invention relates to the technical field of tactile feedback interfaces, in particular to a directional focusing tactile feedback interface. Background technique [0002] There are two main forms of existing tactile feedback cases. One is that a piezoelectric element is placed under each touch area, and the piezoelectric element senses human operation while providing vibration feedback; second, on the interface of tactile feedback Place one or two piezoelectric elements, this piezoelectric element is mainly used to provide vibration feedback, and sensing is provided by capacitive sensors or resistive sensors; [0003] For the interface with multiple tactile feedback areas, the first method requires not only multiple piezoelectric elements, but also multiple voltage drive modules, which results in excessive cost; the second method of feedback has a difference in the vibration amplitude of the entire interface Larger, the tactile feedback provided to the o...
