The hard drive (20) is electrically connected to the hub (30). The hub (30) comprises two or more USB interfaces (31) arranged at a side wall of the hard drive enclosure (10). The hard drive storage device integrates together a storage functionality of the hard drive and a data interface expansion functionality of the hub, and is easy to use and carry.

An electronic device which can be installed and removed in an apparatus using only one hand includes a base and a positioning member. A positioning opening is formed on a first side surface of the base, and a channel is formed in the base with one end connected to the positioning opening. The positioning member is located in the channel and has a holding groove exposed from a front surface of the base. The positioning member is movable along the channel between a released position and a compressed (mounted) position. In the released position, a locking portion of the positioning member extends out of the channel via the positioning opening, in the compressed position the locking portion is retracted into the channel.

An event marking device marks the real time at which notable events occur. When a notable event occurs, a user causes the event marking device to generate a trigger signal. The event marking device includes a real-time clock. When the user causes a trigger signal to be generated, a microcontroller of the event marking device reads the real-time clock and writes trigger event data to a memory indicating a real time at which the trigger signal was generated. The event marking device outputs the trigger event data to an external device.

An audio device, comprising a housing, a circuit board, a rotating shell, a contact switch, and a trigger; the circuit board is disposed in the housing; the housing is rotatably connected to the rotating shell; the contact switch is disposed on the circuit board, and the trigger is disposed on the rotating shell; during rotation of the rotating shell relative to the housing, the trigger triggers the contact switch.

A hard disk drive tray for accommodating a hard disk drive is provided. The hard disk drive tray has a front frame. An elastic cantilever plate is extended from each of two ends of the front frames. The couple of elastic cantilever plates are arranged parallel with each other for clamping the hard disk drive between the couple of elastic cantilever plates. A lateral surface of each elastic cantilever plate is covered by a side case and an expansion fastening bolt for fastening the hard disk drive is arranged protruding from the other lateral surface of each elastic cantilever plate. The hard disk drive is clamped by, the elastic cantilever plates, a simplified structure of the hard disk drive tray. The elastic cantilever plate is covered by the side case and thereby reinforced.

The embodied invention is a bendable portable hard drive holder with four foldable arms, an adhering central element, a surface adhering element for attachment to a surface, and bendable metal in the 4 foldable arms. The invention is suited for portable use with a hard drive as the two adhering elements are separable, such as by use of a magnet or hook and loop attachment. The holder remains on the hard drive for improved convenience.

A pull-out aiding device includes a pulling component and a gripping component. The pulling component includes a first pivotal connection portion and a corresponding portion. The corresponding portion abuts against a target. The gripping component includes a second pivotal connection portion and an operating portion. The second pivotal connection portion is pivotally connected to the first pivotal connection portion, such that the gripping component rotates about the second pivotal connection portion.

A mobile device for recording a face to face personal meeting between two or more participants that includes a portable casing that defines a single interior space, a recording means, a microprocessor with a computer program, a memory means, an identification sub-system, and a sensing reader. The microprocessor, the memory means and the identification sub-system are positioned inside the casing and the sensing reader is positioned inside the casing or physically connected to it. The identification sub-system is designed to identify personal keys of the participants of that meeting. The mobile device is designed to make recording of that meeting and to save it in the memory means. The computer program is designed to lock the recording to disable access to it, and to unlock the recording to enable access to it when the sensing reader identifies the personal keys of the participants of that meeting.

The present invention relates to a record player with a cabinet, a speaker, a movement base-plate, and a movement, wherein the cabinet contains a first opening and a second opening, the first opening being positioned on a side surface, a bottom surface or a top surface of the cabinet, and the second opening being positioned on the top surface of the cabinet; the speaker is positioned at the first opening and is electrically connected to the movement; and the movement base-plate is positioned at the second opening and includes a recessed part in which the movement is placed. The record player of the present invention includes a built-in speaker and a good resonance chamber formed therein, therefore the sound quality played by the record player can be effectively improved.
