Abstract: An air shutter comprises a holder, two compressible elastic members, a plurality of blades, and two cover plates. The holder comprises a central hub, an outer frame and a plurality of connecting pieces, and the outer frame has two annular grooves for receiving the two compressible elastic members. Each of the plurality of blades locates between two adjacent connecting pieces and one end is pivotally connected to the central hub and the other end is pivotally connected to the two compressible elastic members. In a windless state, a gap between two adjacent connecting pieces is closed by one of the blades, and when the windless state changes to a windy state, each blade is rotated by a wind force and area of the gap expands with the increase of the wind force. A radiating fan comprising the air shutter is also provided.

Abstract: An electronic device includes a case, a plug and a locking assembly. The plug is inserted into the socket on the sidewall of the case and the locking assembly includes a locking portion seat and a locking portion. The locking portion seat mounted to the receiving hole of the sidewall of the case includes a base and a hollow locking portion sleeve, the locking portion sleeve extends from the base and is received in the receiving hole of the case. The locking portion includes a securing arm, a loop and a clasp, the securing arm is inserted into the through hole to connect the locking portion and the locking portion seat, a hook at the free end of the loop is latched after the plug is collared in the loop.

Abstract: A communication device includes a circuit board including a plurality of contact pads and a microphone. The microphone includes a cell, a cylindrical cap contoured to define a receiving space receiving the cell, a protecting ring extending along a periphery of a bottom portion of the cylindrical cap, and a plurality of contact posts positioned on the bottom portion and contacting the plurality of contact pads to electrically connecting the circuit board and the microphone. The cylindrical cap, the protecting ring, and the contact posts are integrally formed. A height of the protecting ring is greater than that of each of the contact posts such that the protecting ring surrounds the contact pads and the contact posts to protect the microphone from dust.
