Abstract: An auxiliary mounting device includes a mounting seat mounted with an electronic device thereon and having an upright rear wall formed with a through hole that is aligned with a rear opening unit in a housing of the electronic device. An upright reflecting plate is connected to a rear surface of the rear wall, is disposed adjacent to the through hole, is pivotable about a vertical axis relative to the rear wall, and is operated at a used position, where a desired angle is formed between the reflecting plate and the rear surface of the rear wall such that sound waves of an audio output reproduced by a loudspeaker of the electronic device propagate rearwardly from the electronic device through the through hole in the mounting seat and are then reflected by the reflecting plate so as to propagate sidewardly and frontwardly.

Abstract: The invention provides a holder having a main body, a fixing module and an actuating module. Both the fixing module and the actuating module are positioned on the main body. When the actuating module moves along a first direction, the fixing module is driven from either a release state or a fixed state to another state along a second direction different from the first direction. The invention further provides a holder applied to an electronic apparatus. The holder has a main body and a detachable base. The detachable base is positioned on the main body, and has a base cover and a circuit board. The base cover has a connecting part. The circuit board is covered by the base cover, and has a plurality of pins for connecting to a connecting port of the electronic apparatus.

Abstract: A displaying apparatus frame used for covering an exterior of a display apparatus. The displaying apparatus frame has a main frame and a sliding cover. The main frame has an opening corresponding to a display surface of the display apparatus. The sliding cover is connected to the main frame in a sliding way, and the sliding cover slides along a direction that is not parallel to the display surface.
