Abstract
There is provided a force sensor including a substrate and a polymer material layer. The substrate has a circuit layout that includes a first electrode and a second electrode configured to form a capacitor therebetween. The polymer material layer covers at least on a space between the first electrode and the second electrode, and is used to change capacitance of the capacitor while being pressed. The force sensor is arranged inside a stem of an earphone for detecting the user input.
