Abstract: A method of removing noise and an electronic device thereof are provided. The electronic device includes a speaker, a first sensor configured to output a first signal by obtaining noise around the electronic device, a second sensor configured to output a second signal by detecting vibrations around the electronic device, and a controller configured to determine whether the second signal satisfies a condition of not exceeding a certain threshold value, and output an acoustic signal to be output through the speaker based on the first signal according to a result of the determination.

Abstract: Disclosed is a vacuum deposition apparatus, which comprises: a chamber mounted with a source for jetting an application material in the gaseous state for deposition onto a substrate; heaters formed to the inner wall of the chamber and internal parts; a pump for aspirating air out of the chamber; and a plurality of cold traps interposed between the chamber and the pump for cooling the air aspirated by the pump to remove the application material from the air. According to the vacuum deposition apparatus, it is possible to prevent direct damage to the internal parts or the inner wall of the chamber by application materials accumulated thereon. Additionally, the plurality of cold traps prevent pollution and stoppage in continuous production which allows substitution to be carried out without stoppage. Therefore, productivity may be improved compared to other equipment with similar specifications.
