Abstract: A protective case for protecting an electronic device includes a hollow main body to fit the electronic device therein, a support formed on a back of the case. The support includes a first protrusion, and a second protrusion spaced from the first protrusion. The first protrusion defines a first slot, and the second protrusion defines a second slot aligned with the first slot, the first slot and the second slot is for cooperatively receiving a stylus.

Abstract: A combination signal receiving device includes a printed circuit board, a light source, a light cover, a receiving cover, and at least one signal receiver. The light source is mounted on the printed circuit board. The light cover is lighttight except a light transmissive logo. The light cover covers the light source. The receiving cover surrounds the light cover. The signal receiver is mounted on the printed circuit board beneath the receiving cover, configured for receiving outside signal passing through the receiving cover. Light emitted by the light source is incapable of reaching the signal receiver. The combination signal receiving device does not negatively influence the appearance of an electronic apparatus.
