SPEAKER HOLE OPENING/CLOSING DEVICE OF A FOLDER-TYPE MOBILE COMMUNICATION TERMINAL, SPECIALLY IN REFERENCE TO AUTOMATICALLY MOVING A COVER ACCORDING TO A STATE OF A FOLDER AND A LOUD SPEAKER WHEN OPENING/CLOSING A SPEAKER HOLE

摘要

PURPOSE: A speaker hole opening/closing device of a folder-type mobile communication terminal is provided to close speaker holes when a loud speaker is used while a folder is open, by moving a cover having cover holes, and to open the speaker holes if the folder is closed. CONSTITUTION: An earpiece is mounted on an upper end of a folder such that a sound can be produced in inner direction of the folder, while a loud speaker is mounted correspondingly to the earpiece such that the sound can be produced in outer direction of the folder. The sound produced from the loud speaker is transmitted through speaker holes formed on an upper case of the folder. A cover(30) moves along the speaker holes, and closes the speaker holes if the loud speaker is used while the folder is open, then opens the speaker holes if the folder is closed. Cover holes(32) are formed at certain intervals. If the cover holes(32) are faced with the speaker holes, the speaker holes are open while being closed if the cover holes(32) cross the speaker holes.
