    Abstract: An embedded electronic device includes a movable unit, an electrical assembly unit, a fixing unit, and a pushing unit. The movable unit includes a main body and at least one buffer block. The fixing unit includes a top cover that covers the main body. The top cover has a body through hole that allows the main body and the at least one buffer block to move therethrough for protruding upwardly from or retracting downwardly into the top cover. The pushing unit resiliently biases the movable unit to move upwardly until the movable unit is stopped and positioned by the top cover. The movable unit is movable relative to the top cover along an axis between a hidden position, in which the movable unit retracts into the top cover, and an exposed position, in which the movable unit protrudes from the top cover.
