Portable electronic device having a haptic button assembly

A haptic button assembly for an electronic device, comprising:

• an input member defining an input surface and configured to translate along a first translation direction that is substantially parallel to the input surface and a second translation direction opposite to the first translation direction;
• a support member coupled to the input member and configured to extend through a hole defined in an enclosure of the electronic device;
• a magnetic component attached to the support member and configured to generate a magnetic flux;
• a first conductive segment configured to pass a first electrical signal through the magnetic flux thereby causing the input member to move in the first translation direction to produce a first component of a haptic output;
• and
• a second conductive segment configured to pass a second electrical signal through the magnetic flux thereby causing the input member to move in the second translation direction to produce a second component of the haptic output.

An electronic device comprising:

• an enclosure comprising a sidewall, the sidewall defining an opening;
• a haptic button assembly comprising:
• an input member positioned within the opening and defining an input surface;
• a contact member coupled to the input member and positioned inward of the input surface;
• a spring member positioned along a side of the contact member;
• and
• a conductive coil positioned along a side of the spring member opposite to the contact member;
• and
• a processing unit configured to:
• cause an electrical current to be applied to the conductive coil, thereby deflecting the spring member away from the contact member;
• and
• cause the electrical current applied to the conductive coil to be reduced, thereby causing the spring member to contact the contact member resulting in a haptic output at the input surface.
