A lithium ion battery graphite negative electrode material and preparation method thereof. The lithium ion battery graphite negative electrode material is a composite material including graphite substrates, surface coating layers coated on the graphite substrates and carbon nanotubes and/or carbon nanofibers grown in situ on the surface of the surface coating layers. The preparation method thereof includes, in solid phase or liquid phase circumstance, the coated carbon material precursor forms the surface coating layer of amorphous carbon by carbonization, and then carbon nanotubes and/or carbon nanofibers having high conductive performance are formed on the surface of the surface coating layers by vapor deposition. This coating mode of the combination of solid phase with gas phase or of liquid phase and gas phase makes the amorphous carbon formed on the surface of the graphite substrates more uniform and dense. The lithium ion battery graphite negative electrode material has properties of high charging-discharging efficiency at first time and excellent cycle stability at either high or low temperatures. The charging-discharging efficiency at first time is up to more than 95%, and the capacity retention after 528 cycles is more than 92%.

An electronic device housing includes an outer casing, a microphone, and a recess in the outer casing proximate to the microphone. A base of the recess has a first adhesive portion and an adjacent first non-adhesive portion, and a hole is defined in the first non-adhesive portion and the recess. The hole and the recess define an acoustic pathway for sound external to the outer casing to reach the microphone. The first adhesive portion and the first non-adhesive portion have different shapes.

Electronic device housing

A housing includes a base housing and a reinforcing frame fixed with the base housing. The base housing includes a base plate, a peripheral sidewall extending outward from a peripheral edge of the base plate, and an inclined supporting peripheral wall extending inward from a distal end of the peripheral side wall toward a central portion of the base plate. The reinforcing frame is securely mounted on the inclined supporting peripheral wall of the base housing. The reinforcing frame includes a mounting portion having an inclined bottom surface resisting against and fixing with the corresponding inclined supporting peripheral wall of the base housing. An electronic device using the housing is also provided.

Housing and electronic device

A protective housing for an electronic device includes a main body, a protective cover, and a connecting mechanism. The protective cover is rotatably and detachably mounted to the main body by the connecting mechanism. The connecting mechanism includes a first magnetic assembly, a second magnetic assembly, and a mounting base. The first magnetic assembly is assembled within the main body, the second magnetic assembly is assembled within the mounting base. The mounting base is pivotally hinged to the protective cover, and the first magnetic assembly and the second magnetic assembly attract each other, thereby connecting the main body and the protective cover together.

Protective housing for electronic device

A magnetic field measuring device includes a support base, a measuring mechanism, and a displacement sensor. The measuring mechanism is positioned on the support base, and includes a mounting plate, a swing arm, a connecting member, an elastic member, and a measuring magnet. The mounting plate is connected to the support base. The swing arm is rotatably positioned on the mounting plate. The elastic member is positioned between the connecting member and the swing arm. The measuring magnet is connected to the swing arm, opposite to the support base. The displacement sensor is positioned on the support base, opposite to the swing arm.

Magnetic field measuring device

An electronic device includes a housing and an installation assembly. The housing defines an opening. The installation assembly includes a fixing member and a holding member. The fixing member includes a base and a fixing portion protruding from the base. The base defines an entrance corresponding to the opening. The holding member comprising a holding portion and an engaging portion formed on an end of the holding portion. The fixing portion runs through the opening, and the base abuts against an outer surface of the housing with the entrance corresponding to the first opening. The engaging portion is engaged with the fixing portion to fix the holding member to the fixing member in the housing, and the engaging portion abuts against an inner surface of the housing, such that the installation assembly is fixed the housing surrounding the first opening.

Electronic device with clip card installation assembly

A dust cover includes an anti-dust portion and an adhering portion integrally formed for framing the anti-dust portion. The anti-dust portion is a mesh sheet. The adhering portion is integrally formed on the anti-dust portion via a heat pressing process. The anti-dust portion is a coarser mesh, and the adhering portion is a mesh sheet with finer holes. The disclosure further provides a method for making the dust cover and an electronic device using the dust cover.

A shielding mechanism includes a shielding cover, a pivot shaft, a shielding member, and an elastic member. The shielding cover defines an insert hole. The shielding member is rotatably mounted to the shielding cover via the pivot shaft, and covers the corresponding at least one insert hole. The elastic member is sleeved on the pivot shaft and elastically resists against the shielding member. An electronic device using the shielding mechanism is also provided.

Shielding mechanism and electronic device

A housing for a portable electronic device includes a bottom shell and a plurality of protection blocks. The bottom shell has a plurality of corner portions, each corner portion includes an engaging recession recessed from an outer surface of the corner portion. The plurality of protection blocks are respectively assembled within the corresponding engaging recessions of the bottom shell, which provide protection in the form of having a double skin. Each protection block together with one corresponding engaging recession of the corner portion of the bottom shell cooperatively defines a buffering area. The protection blocks have an elastic coefficient great than that of the bottom shell and are located on each corner portion, at the point of the greatest vulnerability to impact damage.
