Abstract

A force operation sensing device is provided. The device includes an input operation unit comprising a first operating member integrally formed with a housing, a magnetic member disposed inside the input operation unit, and an oscillating circuit comprising a first inductor element and a second inductor element, wherein when a force operation is applied to the first operating member, the oscillating circuit is configured to generate a first variable resonant frequency based on an interaction between the first operating member and the first inductor element, and generate a second variable resonant frequency based on an interaction between the magnetic member and the second inductor element.
