Force sensing device with common noise reduction and electronic device

A force sensing device disposed in an electronic device having a first force member and a second force member formed on a conductive housing, the force sensing device comprising:

• a substrate disposed inside the housing and spaced apart from inner side surfaces of the first force member and the second force member;
• a first inductor element disposed on a first surface of the substrate and spaced apart from the first force member, the first inductor element having a first inductance, which is variable at a time of force input pressing the first force member;
• a second inductor element disposed on the first surface of the substrate and spaced apart from the second force member, the second inductor element having a second inductance, which variable at a time of force input pressing the second force member;
• and
• a support member comprising a first end contacting the first surface of the substrate at a location between the first inductor element and the second inductor element and a second end contacting an inner side surface of the housing at a location between the first force member and the second force member.
