Abstract: A light-indicating input device has a housing having a plurality of function keys and control keys, with the control keys being divided into a first group of control keys and a second group of control keys, with a first function key controlling the first group of control keys, and a second function key controlling the second group of control keys. The input device also includes a micro controller, and first and second light sources coupled to the micro controller, with the micro controller and the light sources located within the housing. Activation of the first function key causes the micro controller to illuminate the first light source to illuminate only the first group of control keys, and activation of the second function key causes the micro controller to illuminate the second light source to illuminate only the second group of control keys.

Abstract: An angle-adjustable mechanism for a speaker system includes a housing and a plurality of speakers. The housing has an opening for accommodating and pivoting a console within the opening. The housing and the speakers can therefore be rotated to a desired angle relatively to the console. The speaker system may be alternatively coupled, by way of example, to either a computer system or an MP3 player.

Abstract: An input device has a body that includes a plurality of electronic components therein, and a compartment located in the body and isolated from the electronic components. The input device has a main cover mounted on the body, an additional electronic device retained inside the compartment, and a subsidiary cover pivotably coupled to the body and covering the compartment in a closed position.

Abstract: An illuminating computer input device includes a base, a housing and a light source mounted inside the housing, wherein the housing is transparent or translucent. An covering layer is applied on an outer surface or an inner surface of the housing. A patterned-window is further formed in the covering layer by removing a portion of the covering layer from the housing. By such arrangement, light generated by the light source is able to transmit out of the housing via the patterned-window so as to create an illuminating effect.
