AI Technical Summary

Technical Problem

When detecting the parameters related to the button pressure of electronic equipment, the prior art has problems such as the inability to accurately identify the absolute pressure degree, the difficulty in miniaturizing the structural strain gauge, the slow software recognition and large errors.

Method used

A detection module is provided, including a fixture, a sensing assembly and a conductive member. The sensing assembly consists of electrode parts and inductor parts stacked on each other. The conductive parts are located in the electric field and the magnetic field. When one end of the body is pressed, the other end moves, causing the electric field and the magnetic field to change. The output signal is used to complete the press detection and pressure parameter detection.

Benefits of technology

It realizes accurate identification of the pressure degree and force, is easy to integrate, and the structural design is suitable for consumer electronic equipment without taking up too much space.
