Abstract: An electronic device such as a media player is formed from electrical components such as integrated circuits, buttons, and a battery. Electrical input-output port contacts are used to play audio and to convey digital signals. Electrical components for the device are mounted to a substrate. The components are encapsulated in an encapsulant and covered with an optional housing structure. The electrical input-output port contacts and portions of components such as buttons remain uncovered by encapsulant during the encapsulation process. Integrated circuits are entirely encapsulated with encapsulant. The integrated circuits are packaged or unpackaged integrated circuit die. The substrate is a printed circuit board or is an integrated circuit to which components are directly connected without any printed circuit boards interposed between the integrated circuit and the components.

Abstract: Accessories such as headsets for electronic devices are provided. A headset may be provided with a button controller assembly that has user-actuated buttons and a microphone. The microphone may be formed by mounting a microphone transducer on a printed circuit board. A housing may be mounted over the transducer to form a sealed cavity for the transducer. Circuitry may be mounted on portions of the printed circuit board that extend beyond the edges of the microphone housing. The button controller assembly may have dome switches. The dome switches may have a housing that encloses dome switch components and that forms a structural internal part for the button controller. The dome switch housing structure may have tabs or other engagement features that mate with corresponding engagement features in a button member. The button member may be pressed by a user to actuate a desired dome switch.
