An electronic device includes a main body defining an opening, and a key mechanism secured in the opening. The key mechanism includes a fixing mechanism, a circuit board and a key. The fixing mechanism includes a tab and a support. The tab protrudes from a sidewall of the opening. The support includes an elastic supporting rib connected to the tab. The circuit board is fixed on the support and includes a switch. The key is rotatably connected to the fixing mechanism actuates the switch to generate an input signal. The supporting rib applies a restoring force to the key.

An elastic contact includes a first elastic piece and a second elastic piece. The first elastic piece includes a base configured for being soldered to a circuit board and a connection part. The second elastic piece includes a contact part configured for resiliently pressing against an element and a connection part. Two sidewalls of one of the connection part bend to form grooves for receiving the other connection part. Limiting means are formed on either of the connection parts for limiting sliding range of the elastic pieces relative to each other. The first elastic piece of the elastic contact can be soldered to the circuit board by a SMT machine, thus the assembly efficiency is improved.

A media playing device is provided. In an exemplary form, the media playing device includes a housing having a cylindrical end with an opening. The media playing device also includes a hollow turning knob. The knob has two protrusions on its inside surface. The media playing device additionally includes a PCB disposed inside the housing with a micro controller unit (MCU) and a pair of switches. The medial playing device further includes an attachment means for attaching the knob to the cylindrical end of the housing and allowing the knob to rotate with respect to the cylindrical end. When the knob is rotated in clockwise direction or counterclockwise direction, one of the two protrusions moves within the opening and can be moved to a position to contact one of the two switches to activate the switch. The activated switch sends a signal to the MCU and the MCU execute an operation.

An electronic reader includes a cover, a middle frame and a paper clamping mechanism. The cover defines a hollow space and includes a bezel defining an opening. The middle frame is secured within the hollow space and includes a connection portion extending between two edges of the opening. The paper clamping mechanism is used for clamping paper on the electronic reader and includes a clamping member, a pivot, and an elastic element. The clamping member is received in the opening and defines a sliding groove. Two ends of the pivot extend through the sliding groove and are received in the bezel, which movably connects the clamping member to the cover. The elastic element is fixed on the bezel to apply a pushing force to the clamping member. Two ends of the clamping member resist the elastic element and the connection portion respectively.

An electronic device having retractable hanger includes a housing, a display panel, and a hanging mechanism. The display panel is mounted on the housing. The hanging mechanism is arranged in the housing. The hanging mechanism includes a base, a hanger, a movable member, and at least one resilient member. The base is secured in the housing. The hanger slides relative to the base and defines a hanging hole, a groove with corners, and protrusions by each corner. The movable member includes a first end and a second end, wherein the first end is rotatably connected to the base and the second end slides in the groove of the hanger.

A media playing device includes a housing with a cylindrical end and a middle portion, a knob, a PCB, a cover, and an attachment means. The end has a reduced diameter with respect to the middle portion, thus forming a step, and has an opening. The knob has a cylindrical inside surface with two protrusions and is attached to the housing with the two protrusions being located within the opening. The PCB has a micro controller unit (MCU) and at least one switch. The cover is detachably attached to the housing and together with the step limit the axial movement of the knob. The attachment means is used for attaching the cover to the housing. When the knob is rotated to a position where one of the contacting protrusions contacts the switch, the switch is activated and sends a signal to the MCU, the MCU executes an operation in response to the signal.
