Abstract

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 corresponding to the speaker holes, and to open the speaker holes if the folder is closed, so that it is easy to transfer sound to the user. The invention is characterized in the cover which 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. The disclosed device has a motor for driving the cover and a controller which can move the cover automatically and open / close the speaker holes according to the state of the cover and the speaker.

Description

technical field [0001] The present invention relates to a speaker of a mobile communication terminal, more specifically, to a speaker opening and closing device for a flip-type mobile communication terminal, which moves a cover with a cover hole corresponding to the speaker hole, and when the speaker is opened in the flip When it is used in the closed state, the speaker hole is blocked, and when the flip cover is closed, the speaker hole is opened, so that it is easy to transmit sound to the user. Background technique [0002] Generally speaking, a mobile communication terminal has a transmitter-microphone and a receiver-earphone. Recently, in addition to the above-mentioned earphone, another loudspeaker has been added, so that a "speakerphone" call can be realized through the mobile communication terminal. [0003] Refer below Figure 5 and Image 6 , a brief description of the usual flip-type mobile communication terminal, Figure 5 It is a perspective view of an open sta...
