Title: PRESSURE-SENSING STRUCTURE, AND ELECTRONIC PRODUCT
Abstract:
In a pressure-sensing structure (100), a first mounting surface (10a) of a substrate (10) is provided with a first elastic carrier (20), and the first elastic carrier is provided with an electronic element. Upon distortion of the substrate (10), the elastic carrier is bent and distorted along with the substrate (10), and the substrate (10) amplifies a strain signal. A strain sensing member can detect a bending or distortion amount of the substrate (10), and a signal measurement circuit (40) outputs an identifiable electrical signal. The pressure-sensing structure is a sensor structure having high accuracy, reliability, and sensitivity. By attaching the pressure-sensing structure (100) to a panel (201) or a side bezel (202) of an electronic apparatus, the pressure-sensing member detects bending or distortion upon a press on the panel (201) or the side bezel (202), and the signal measurement circuit (40) outputs an identifiable electrical signal. The electronic product can avoid the condition in which a conventional mechanical button is employed and introduces a seam on an exterior causing difficulties for water-proof and dust-proof functions, a short service-life, and installation difficulties.
