Abstract: An electronic device (100) having a speaker (30) located in a sealed and separate speaker enclosure is described. The electronic device includes a housing (20) having a cavity (22) receiving the speaker with at least one conductive post (342), a circuit board (70), and a cover (60) with at least one through hole (622). The cover is disposed between the housing and the circuit board. One end of the conductive post passes through the through holes and electronically connects the speaker to the circuit board.

Abstract: A hinge mechanism for interconnecting a cover and a main body of a foldable electronic device, includes a sleeve, a shaft unit, an elastic member and an engaging body. The sleeve has two opposite gaps formed in the interior wall thereof, the shaft unit includes a shaft portion and an end portion formed at an end of the shaft portion, the shaft portion defines a slot therein, the elastic member includes a central wall and two opposite flanges. The shaft unit, the elastic member and the engaging body are mounted into the sleeve, the slot receives the central wall and the two flanges extends into the two gaps correspondingly, the shaft portion is fixed with the engaging body, the elastic member urges the shaft unit return to original position when the shaft unit rotates relative to the sleeve.
