Abstract: A portable electronic device includes a main body defining a locking hole therein and an auxiliary body having a latch therein. The latch includes a button, a slider, and a spring member positioned between the button and the auxiliary body. The slider includes a locking portion retractably inserted into the locking hole. The slider is slidably engaged with the button in a manner that when the button is pressed along a first direction, the slider is pushed by the button to slide along a second direction perpendicular to the first direction, thereby retracting the locking portion from the locking hole. The spring member is for elastically loading the button in a third direction opposite to the first direction.

Abstract: A storage medium player includes a base, a printed circuit board mounted in the base, and an indicator device. The base includes an upper body and a lower body. One of the upper body and the lower body includes a first engaging portion and defines a hole. The indicator device includes an indicating lamp and a shield arranged between the indicating lamp and the hole. The indicating lamp is electrically connected with the printed circuit board so as to be supplied with an operating voltage by the printed circuit board. The shield is mounted in the base with one end thereof being engaged with the first engaging portion. The shield includes a main body and a protruding portion extending away from the main body. At least a part of the protruding portion is received in the hole.

Abstract: A portable electronic device with a fastening mechanism includes a main body and a subsidiary casing. The main body comprises a bottom wall and a side wall extending from one edge of the bottom wall. A receptacle is defined in the sidewall thereof. The subsidiary casing is configured for receiving a battery therein. The subsidiary casing comprises a latch formed thereon. The latch is engaged into the receptacle to prevent the subsidiary casing from moving along a first direction, wherein the latch is inserted into the receptacle along a second direction that is perpendicular to the first direction when the subsidiary casing is assembled to the main body.

Abstract: A disc player includes a base, a lid rotatably pivoted to the base, and an opening and closing mechanism secured to the base. The opening and closing mechanism includes a compression spring providing a restoration force and a pushing button for applying a pushing force thereon. The pushing button includes a locking portion for releasing the lid from the base and for clasping the lid to the base, and at least one wedged potion for interfering in one end of the compression spring to fix the compression spring.

Abstract: A lock mechanism for a digital video player includes an elastic component, a switch, a main body, and a lid pivotally connected to the main body. The switch forms a switch button, a catch and a post for supporting the elastic component. The main body includes a cover and a housing. The cover defines a through hole thereon. The housing mounts at least one support for slideably supporting the switch, a stop plate connecting with the elastic component, and a second notch for accommodating the switch button. The lid mounts a hook on the bottom surface thereof corresponding to the through hole and being capable of hooking the catch when the lid is locked.

Abstract: A hinge assembly for a media player having a main body and a cover body, includes a first hinge subassembly. The first hinge subassembly includes a first base plate adapted to be secured to the main body of the media player, a first joint axle secured to the first base plate, a first hinge arm adapted to be secured to the cover of the media player, several resilient bushings surrounding the first joint axle and arranged adjacent the first end of the first hinge arm, and an adjustable fastener coupled to the first joint axle for exerting an adjustable force applied to the first end of the first hinge arm. The first hinge arm has a first end pivotally coupled to the first joint axle. The adjustable fastener is positioned to generate a friction force between the first end of the first hinge arm and the at least one resilient bushing, and the friction force is sufficient to overcome gravitational force acting on the cover of the media player.
