Abstract: A cyclone dust collecting apparatus for a vacuum cleaner includes a hollow cylindrical cyclone body having an open upper end through which air and contaminants are drawn in and a dust discharge port located proximate a lower end of the cyclone body. The dust discharge port receives contaminants that have been separated from the air by centrifugal force and discharged from the cyclone body. The apparatus further includes a dust receptacle connected to the cyclone body for collecting the contaminants discharged from the cyclone body through the dust discharge port. A base member is connected to and closes the lower end of the cyclone body and the dust receptacle, and a cover is removably connected to the upper end of the cyclone body and the dust receptacle. The cover has an air intake channel for drawing in outside air and contaminants into the cyclone body and an air discharge channel for discharging clean air from the cyclone body.

Abstract: Disclosed are a connection method for a microphone mounted in a mobile radio communication unit and a connection structure thereof, in which the connection of the microphone to a printed circuit board is made using circular conductive contacts formed at a holder made of a rubber material to protect the microphone, thereby being capable of conveniently achieving the connection between the microphone and the printed circuit board without using wires involving a welding process, as in conventional cases, while reducing the assembling time of the product, achieving an improvement in workability, and preventing an interference with peripheral components and a degradation in the connection resulting in a degradation in the reliability of the product. Alternatively, the connection of the microphone to a printed circuit board is made using a connector coated with a conductive adhesive (or a nonconductive adhesive) at both surfaces thereof.
