Problems solved by technology

[0002] At present, most of the analog buttons are realized by means of potentiometer, silicone pad with carbon film, Hall, etc. However, the realization of the above-mentioned analog buttons generally involves complex structures and has high requirements for the applicable environment
For example, the structural design of potentiometers and silica gel pads with carbon film is more complicated, and the error is relatively large (for example, the resistance value of carbon film printing has about 20% error), while the Hall mode analog button requires higher structural accuracy, and High requirements on the surrounding magnetic environment

Abstract

The invention discloses a simulated button, a terminal device and a control method of the simulated button, wherein the simulated button comprises: a base plate; a key cap, which is movably connected to the base plate, to move close to and away from the base plate; one of the substrate and the keycap, and send detection light to the other, and the photoelectric sensing device also receives the reflected light of the detection light; and a signal processing unit, and the photoelectric sensing device It is electrically connected to determine the pressing stroke of the analog key by receiving the reflected light fed back by the photoelectric sensing device, and sends out a corresponding operation signal according to the pressing stroke. The technical scheme of the present invention provides a photoelectric analog key.

Description

technical field [0001] The present invention relates to the technical field of analog buttons, in particular to an analog button, a terminal device and a control method of the analog button. Background technique [0002] At present, most of the analog buttons are realized by potentiometers, silicone pads with carbon films, and Halls, etc. However, the implementation of the above-mentioned analog buttons generally involves complex structures and requires high applicable environments. For example, the structure design of potentiometer and silicone pad plus carbon film is more complicated, and the error is large (for example, the resistance value of carbon film printing has about 20% error), while the Hall-type analog button has higher requirements on structural accuracy, and There are high requirements for the surrounding magnetic environment. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide an analog key, which aims to provide a pho...
