Sealed button for an electronic device
First Claim
1. An electronic device comprising:
- an enclosure defining an interior;
a button connected to the enclosure, the button comprising;
a button cap defining a user input surface;
a flexible member separating the interior of the enclosure from an external environment and having an interior surface facing the interior of the enclosure and exterior surface facing the external environment, the flexible member being aligned with the button cap and connected thereto; and
a strain sensor connected to the interior surface of the flexible member; and
a processing element in communication with the strain sensor;
wherein when a force is exerted on the button cap, the flexible member bends; and
the strain sensor detects a user input corresponding to the force and provides a signal to the processing element corresponding to the user input.

Abstract
One embodiment of the disclosure includes an electronic device including an enclosure (214), a button (106), and a processing element (not shown). The button is connected to the enclosure and includes a button cap (234) defining a user input surface, a flexible member (238) having an interior surface (270) and exterior surface. The flexible member is aligned with the button cap and is connected thereto. The button further includes a strain sensor (244) connected to the interior surface of the flexible member, the strain sensor is in communication with the processing element. When a force is exerted on the button cap, the flexible member bends and the strain sensor detects a user input corresponding to the force and provides a signal to the processing element corresponding to the user input. In some embodiments, the button may be substantially or completely waterproof.
